Dennis uses a soft-sided foot locker to store his sports equipment in his bedroom. The foot locker is 38 inches long and 12 inches wide and has a volume of
7,752 cubic inches. What is the height (in inches) of the foot locker?
A. 204
B. 17
Answer:
So.. I believe the answer is 17
Step-by-step explanation:
In order to get your answer, you would first multiply 38*12 which is 456
Then you would get that number (456) and divide it by 7,752
So 7,752/456 is 17

Answer:
4x10⁷is more than 4x10¹⁰
Someone explain to me if this is correct?
Answer:
Yes, that is correct.
Step-by-step explanation:
W = x
L = ?
A = x^2 + 12x
(x^2 + 12x)/x = x + 12
L = x + 12
Subbing in 10 for each X, we get:
Perimeter: 64
2(10) + 2(10 + 12) = 20 + 44 = 64
Area: 220
10 * 22 = 220
Part A looks perfect. You've shown that x^2+12x factors into x(x+12) indicating that x is the width and x+12 is the length. Convention usually has the length be longer than the width, but to be honest, the order doesn't really matter (since we can multiply in any order we want).
----------------
Part B is a bit hazy. You show that 10 * 22 = 220 is the area, so you imply that the rectangle has width 10 and length 22. However, you don't directly mention the dimensions of the rectangle.
You can pick either x^2+12x or x(x+12). I prefer x(x+12) as its easier in my opinion. You don't need to do both.
All you really need to do is say that if x is the width and x = 10, then the width is 10. Furthermore, if x+12 is the length then x+12 = 10+12 = 22 is the length.
How did the temperature change if: At first it increased by 25% and then decreased by 40%
Answer:
24.6 % decrease
Step-by-step explanation:
Let x be the original temperature
Increase by 25%
x + .25x
1.25x
Decrease by 40%
The amount decreased is
(1.25x) *.40
.496x
Subtract that from 1.25x
1.25x - .496x
.754x
We need to find the percent decrease
1 - .754 = .246
24.6 % decrease
Answer:
Temperature decreased by 25%
Step-by-step explanation:
Let initial temperature be t
Step 1
Increase by 25%:
t + 25% = t + 0.25 t = 1.25 tStep 2
Decrease by 40%:
1.25 t - 40% = 1.25 t - 0.4 * 1.25 t= 1.25 t - 0.5 t = 0.75 tTemperature changed from t to 0.75 t
The difference in %:
0.75 t - t = -0.25 t = 25% decreaseTemperature decreased by 25%
you move right 3 units and left 4 units. you end at (-3,-1). where did you start?
Answer:
(-2,-1) is where u start
Step-by-step explanation:
Answer:
(-2,-1)
Step-by-step explanation:
The point we ended at is (-3,-1)
We have moved 4 units left so we will add 4 to -3
● -3+4 = 1
We have moved 3 unirs right so we will substract 3 from 1
● 1-3 = -2
So the initial point was (-2,-1)

Sam can paint the house in 7 days by himself, while Betty can paint the same house in 42 days. How long would it take Sam and Betty to paint the same house together?
Answer:
It would take 6 days for Sam and Betty to paint the same house together.
Step-by-step explanation:
Let x represent the time it takes ( in days ) to complete painting the house working together. Our approach here is to add the rates of the two people, equal to the total rate, or 1 / 7.
Sam's rate = 1 / 7 ( 7 days to paint 1 house ),
Betty's rate = 1 / 42 ( 42 days to paint 1 house )
1 / 7 + 1 / 42 = 1 / x - now let us solve for x, our solution
1 / 7 + 1 / 42 = 1 / x ( multiply either side by 42x )
7x = 42,
x = 42 / 7 = 6 days

Given: ΔABC, AC = BC, AB = 3 CD⊥ AB, CD = 3 Find: AC
3.35 (3 sig.fig)
Given:Triangle ABC
AC = BC, AB = 3, CD perpendicular to AB, CD =3
Find:AC (Hypotenuse)
Step-by-step solution:AC = BC shows that Triangle ABC is an isosceles triangle.
As CD is perpendicular to AB, and, both sides
(AC & BC) have equal angles and length, making the line CD cut right across the triangle.
(Point D is in the middle of Line AB)
Resulting in 2 EQUAL triangles in Triangle ABC.
To find one of the 2 triangles:
1. Take Line AB and divide it in half as both sides are equal.
Line AD = 3 / 2
= 1.5
2. Use the Pythagoras Theorem to find Line AC (Hypotenuse). [c^2 = a^2 + b^2]
a : Line AD = 1.5
b : Line CD = 3
c^2 = 1.5^2 + 3^2
c^2 = 2.25 + 9
c^2 = 11.25
c = (Square Root) 11.25
c = 3.35 (3 significant figure)
Therefore, the answer is:
3.35

The segments shown below could form a triangle.
A. True
B. False
Answer:
A True
Step-by-step explanation:
B vertices would be the top of an isosceles
As any equal sides can form an isosceles, the measure of the base could be any size and isnt relevant to the triangle unless we are looking for a calculation for its height, which does not determine shape only equation.
Therefore with sides of triangles if they are equal we cna make the shape consist of any length base as long as it measures less than double than either side length.
Therefore a 1cm base does apply and can form a triangle of two equal sides 7cm and 7cm as the diagram asks.

Each half-inch of a ruler is divided evenly into eight divisions. What is the level of accuracy of this measurement tool?
Answer:
The level of accuracy of the measurement ruler measurement tool is 1/16 of an inch
Step-by-step explanation:
The accuracy of a measurement tool is determined by the ability of the tool measure the accurate value of the actual or standard measurement. The accuracy of a measurement tool depends on its ability to take small measurements
The parameter given includes;
The number of divisions on each 1/2 inch of the ruler = 8
Therefore, the smallest divisions on the ruler = (1/2) inch ÷ 8 = 1/16 inch
Therefore, the level of accuracy of the measurement ruler measurement tool = 1/16 of an inch.

Randomly pick 6 points from a square of side = 1. Show that you can always find 2 points from these 6 that their distance is less or equal to [tex]\frac{\sqrt{2} }{2} }[/tex]
Randomly pick 5 points from a sphere. Show that you can always find a closed semi-sphere ( half a sphere and boundary) that contains 4 points.
Problem 1.
My thinking is that the furthest you can get is have two points at each opposite corner, so the distance between them is sqrt(2). If we have two other points with this property, then all four corners are filled up. It is possible to pick two points where the distance is 1 unit.
Then a fifth point can be placed at the center such that the distance from it to any of the corners is sqrt(2)/2. We placed the fifth point at the center to try to get as far away as possible from the other four points.
Basically we're trying to find the worst case scenario (leading to the largest distance possible) and seeing how we can fill up the square. This establishes the upper bound. Any other kind of scenario will have a distance less than the upper bound.
===================================================
Problem 2.
For this one, I'm not sure what to make of it. The terminology is a bit strange so I'm not going to be fairly helpful here. Sorry about that.
If I had to guess, I'd assume it has something to do with the fact that a plane is uniquely defined by 3 points. That fourth point is not coplanar with the other three, which helps define the semi-spherical portion. The fifth point is just extra. The points can't be all collinear or else a plane won't form. Though to be honest, I'm still not sure about problem 2. I'd get a second opinion.

Using the function f(x)=-x^2+8x-13 find f(4)
Answer:
f(4) = 3
Step-by-step explanation:
f(x) = -[tex]x^{2}[/tex] + 8x - 13
To find f(4), substitute 4 for all instances of x:
f(4) = -(4[tex])^{2}[/tex] + 8(4) - 13
Simplify the exponent:
f(4) = -16 + 8(4) - 13
Multiply:
f(4) = -16 + 32 - 13
Combine terms:
f(4) = 3
Answer:
3
Step-by-step explanation:
You plug in 4.
f(4)= -(4)^2+8(4)-13
f(4)= -16+32-13
f(4)= 16-13
f(4)=3
In a certain freshman class, the number of girls is 83 less than twice the number of boys(b). The total number of students in that freshman class is 259. How many boys and girls are in that class.
Answer:
Boys = 114
Girls = 145
Step-by-step explanation:
Boys = b
Girls = 2b-83
b+2b-83=259
3b=259+83
3b=342
b=114
Boys = b = 114
Girls = 2b-83=228-83=145
The number of boys is 114 and the number of girls is 145
The given expression in algebraic form is written as:
let the number of boys = b
then, the number of girls, g = 2b - 83
given total number of students, t = 259
To find:
the number of boys and girls in the class.Set the following equations to find the number of boys and girls:
number of boys + number of girls = total number of students
[tex]b + g = 259\\\\b + 2b -83 = 259\\\\3b = 259+83\\\\3b = 342\\\\b = \frac{342}{3} \\\\b = 114\\\\The \ number \ of \ girls = 2(114) - 83 = 145[/tex]
Thus, the number of boys is 114 and the number of girls is 145

can the side lengths
form a triangle ?
Answer: No
Step-by-step explanation:
Because 4^2=16
5^2=25
25+16=41
41 squared =6.4031.....
6.4031 does not = 20
Answer: No, a triangle is not possible
The two smaller sides add to 4+5 = 9 which is not larger than 20. For a triangle to be possible, we need to be able to add 2 sides to make them longer than the third side. This is an application of the triangle inequality theorem.
