Step-by-step explanation:
4p - 3(p + 5) = 3p - 17
Answer:
p=1
Step-by-step explanation:
4p - 3(p + 5) = 3p - 17
Distribute
4p -3p -15 = 3p -17
Combine like terms
p -15 = 3p -17
subtract p from each side
p-p -15 = 3p -17-p
-15 = 2p -17
Add 17 to each side
-15+17 = 2p -17+17
2 = 2p
Divide by 2
2/2 = 2p/2

The wire supporting a 20-foot tall phone pole is attached to the top of the pole, and to the
ground 12 feet from the pole. How long is the wire?
Answer:
22.36 feet
Step-by-step explanation:
This situation forms a right triangle, where the wire is the hypotenuse
Use the pythagorean theorem to find the hypotenuse/wire length:
a² + b² = c²
20² + 12² = c²
400 + 144 = c²
544 = c²
22.36 = c
So, the wire is 22.36 feet long

A hot dog cart charges exactly $0.50 per hot dog. If the equation t=kh represents the total amount a customer is charged, t, for purchasing h hot dogs, what is the value of k?
Answer:
$0.50
Step-by-step explanation:
According to the information given, in the equation t=kh, t is the total amount a customer is charged and h is the amount of hot dogs purchased. So, to be able to get the total amount a customer is charged you have to multiply the amount of goods bought by the price of each good. Because of that, K would be the price per hot dog which is $0.50.
divide 68 into two parts so that the larger number exeed the smaller one by 6
Answer:
31, 37
Step-by-step explanation:
Let the smaller number be x
Therefore, longer number = x + 6
According to the given information:
x + x + 6 = 68
2x + 6 = 68
2x = 68 - 6
2x = 62
x = 62/2
x = 31
x + 6 = 31 + 6 = 37
Thus, the two parts of 68 are 31 and 37.

There are 10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles in a box. If two marbles are drawn at random without replacement, what is the probability that both marbles removed are not blue?
Answer:
7/20
Step-by-step explanation:
10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles = 25 marbles
25-10 = 15
There are 15 not blue marbles
P( not blue ) = not blue marbles / total = 15/25 = 3/5
keep the not blue marble
25-1 = 24 marbles left
15-1 = 14 not blue marbles
P( not blue ) = not blue marbles / total = 14/24 = 7/12
P( not blue, keep, not blue) = 3/5 * 7/12 = 21/60 = 7/20
Answer:
7/20
Step-by-step explanation:
10(blue) + 4(black) + 5(white) + 6(red) = 25(total)
25(total)-10(blue)=15(not blue)
not blue/all = 15/25 = 3/5 = probability that first marble removed are not blue
If we remove 1 marble;
25-1 = 24 (total) , 15-1=14(not blue)
second not blue/all = 14/24 = 7/12 = probability that second marble removed are not blue
probability that both marbles removed are not blue : 3/5. 7/12 = 21/60
21/60 = 7/20

46
O 50
O 200
Answer:
The answer is 46Step-by-step explanation:
f(x) = 4x + 30
g(x) = x - 1
In order to find (fºg)(5) first find ( f • g)(x)
To find ( f • g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g(x)
So we have
( f • g)(x) = 4(x -1) + 30
= 4x - 4 + 30
( f • g)(x) = 4x + 26
To find (fºg)(5) substitute the value of x that's 5 into (f • g)(x)
That's
(fºg)(5) = 4(5) + 26
= 20 + 26
We have the final answer as
(fºg)(5) = 46Hope this helps you

Given the graph below, which of the following statements is true? On a coordinate plane, a graph shows an image with three connected lines. The first line has a negative slope and goes from (negative 5, 6) to (negative 2, 0), the second line has a positive slope and goes from (negative 2, 0) to (2, 2), and the third line has a negative slope going from (2, 2) through (4, negative 2). The graph represents a one-to-one function because every x-value is paired with only one y-value. The graph represents a one-to-one function because it is defined for all x-values. The graph does not represent a one-to-one function because it does not pass through the origin. The graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.
Answer:
The correct option is (D).
Step-by-step explanation:
A one-to-one function can be defined such the every value of x corresponds to exactly one value of y.
That is:
x₁ → y₁
x₂ → y₂
x₃ → y₃
.
.
.
and so on.
Consider the graph.
From the graph it can be seen that for y = 0 and y = 2 there are multiple x coordinates.
So, the graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.
According to the graph it can be concluded that the graph of three lines is not an one one function because the values of 'y' between 0 and 2 are paired with multiple 'x' values.
Given :
On a coordinate plane, a graph shows an image with three connected lines. The first line has a negative slope and goes from (-5, 6) to (-2, 0).The second line has a positive slope and goes from (-2, 0) to (2, 2).The third line has a negative slope going from (2, 2) through (4, -2).Draw the graph of the three lines in order to determine the function is one-one function or not.
The equation of the line passing through (-5,6) and (-2,0) is given by:
[tex]\dfrac{y-6}{x+5}=\dfrac{0-6}{-2+5}[/tex]
[tex]\dfrac{y-6}{x+5}=\dfrac{-6}{3}[/tex]
[tex]y-6=-2(x+5)[/tex]
y + 2x + 4 = 0 --- (1)
The equation of the line passing through (-2,0) and (2,2) is given by:
[tex]\dfrac{y-0}{x+2}=\dfrac{2-0}{2+2}[/tex]
2y = x + 2 ---- (2)
The equation of the line passing through (2,2) and (4,-2) is given by:
[tex]\dfrac{y-2}{x-2}=\dfrac{-2-2}{4-2}[/tex]
y - 2 = -2(x - 2)
y + 2x = 6 ---- (3)
Now, with the help of these three equations, the graph of the three lines can be plotted. The Graph is attached below.
So, according to the graph it can be concluded that the graph of three lines is not an one one function because the values of 'y' between 0 and 2 are paired with multiple 'x' values.
Therefore, the correct option is D).

A cylindrical water bottle with a height of 21 cm and diameter 6.5 cm is fully filled with water. Kelvin wants to pour all the water in the bottle into a cubic container. State thr minimum leght, to the nearest cm, the side of the cube.
Answer:
9 cm
Step-by-step explanation:
First, we need to find the volume of the cylindrical water bottle. The volume of a cylinder is πr²h where r = radius and h = height. In this case, r = diameter / 2 = 6.5 / 2 = 3.25 and h = 21 so the volume is π * 3.25² * 21 = 221.8125π ≈ 696.84. Let's call the length of the cubic container s. The volume of the cube (which is s³) must be at least the volume of the water bottle, therefore:
s³ ≥ 696.84
∛s³ ≥ ∛696.84
s ≥ 8.86566
The smallest integer value that satisfies this is 9 cm.

Express the following in the usual form
(a) 6.25×10-⁵
Answer:
0.0000625
Step-by-step explanation:
[tex]10^{-5}=0.00001[/tex]
[tex]6.25*10^{-5}=6.25*0.00001=0.0000625[/tex]
Answer:
So we need to express [tex]6.25 * 10^{-5}[/tex].
What is being used here is scientific notation, and when the exponent is negative, that means the number is less than 1.
As the exponent is -5, we have to move the coma 5 positions to the left (if it was positive we would have done that put to the right), so:
[tex]6.25 * 10^{-5}=0.0000625[/tex]
If you don't understand what does it mean to move the coma to the left, see this example to understand it:
We move it one time from 6.25 --> 0.625
We move it two times from 6.25 --> 0.0625
We move it three times from 6.25 --> 0.00625
We move it four time from 6.25 --> 0.000625
What we are doing is adding 0 to the left and if the exponent was positive, we would add 0 to teh right.
So now we know that [tex]\boxed{6.25 * 10^{-5}=0.0000625}[/tex]
it is given that 2/3, 8/d and n/39 are equivalent fractions. find the value of d and the value of n
Answer:
d = 12 and n = 26
Step-by-step explanation:
Given that the fractions are equivalent then
[tex]\frac{2}{3}[/tex] = [tex]\frac{8}{d}[/tex] ( cross- multiply )
2d = 24 ( divide both sides by 2 )
d = 12
--------------------------------------
and
[tex]\frac{2}{3}[/tex] = [tex]\frac{n}{39}[/tex] ( cross- multiply )
3n = 78 ( divide both sides by 3 )
n = 26
The fractions represent the same amount or value given that they are
equivalent.
The value of d is 12The value of n is 26Reasons:
Equivalent fractions are fractions that have equal values, therefore;
[tex]\displaystyle \frac{2}{3} = \frac{8}{d} =\frac{n}{39}[/tex]
Which by cross multiplying gives;
2 × d = 8 × 3 = 24
Therefore;
[tex]\displaystyle d = \frac{24}{2} = \mathbf{12}[/tex]
d = 12
Similarly, we have;
[tex]\displaystyle \frac{2}{3} =\frac{n}{39}= \frac{8}{d}[/tex]
Which gives;
2 × 39 = 3 × n
Therefore;
[tex]\displaystyle n = \frac{2 \times 39}{3} = \mathbf{26}[/tex]
n = 26
