Select all the ways the rectangle could have been rotated to get from Frame 1 to Frame 2. 40 degrees clockwise 40 degrees counterclockwise 90 degrees clockwise 90 degrees counterclockwise 140 degrees clockwise 140 degrees counterclockwise Lesson 3
Answer:
40 degrees clockwise
140 degrees counterclockwise
Step-by-step explanation:
The rectangle is rotated in Figure B. The angle of rotation is 40 degrees. If we rotate a rectangle at an angle of 40 degrees clockwise then wit will be at the position as shown in figure B. The 90 degrees angle is perpendicular angle. Rectangle will not reach the desired position. If we rotate the rectangle at 140 degrees counterclockwise this will be the figure B representation. The rotation to 90 degree counterclockwise is either not suitable for the desired rectangle position.
Find the equation of the line below.
Answer:
y = 2x
Step-by-step explanation:
The equation of a line is y = mx + b
We can plug in values for x and y,:
x = 1, y = 2
2 = m + b <- equation 1
x = 4 y = 8
8 = 4m + b <- equation 2
We can multiply equation 1 by 4, getting 8 = 4m + 4b.
We can them subtract equation 1 by equation 2, getting 3b = 0.
Therefore, b = 0.
We can use the equation 2 = m + b and find m:
Since b = 0, m = 2.
The equation is then y = 2x.
A restaurant chef made 1 1/4 pints of mushroom soup. Each bowl of soup holds 5/8 of a pint.
How many bowls of soup will the chef be able to fill?
Answer:
2 bowls of soup
Step-by-step explanation:
1. Make 1 1/4 an improper fraction
1 1/4 = 5/4
2. Then divide 5/4 by 5/8 (KCF - Keep the 5/4 - Change the division sign to multiplication - 'Flip' 5/8 to 8/5)
5/4 x 8/5 = 40/20
3. Simplify the fraction (divide the numerator and denominator by 20)
40/20 = 2
4. Final answer:
2 (bowls of soup)

what is the standard deviation for 54, 36, 30, 28, 27
Answer:
11.18
Step-by-step explanation:
Step 1: average : (54+36+30+28+27) / 5 = 35
Step 2: variance:
sum of the squares of (each number - average value) divided by (n-1)
[ (54-35)^2 + (36-35)^2 + (30-35)^2 + (28-35)^2 + (27-35)^2 ] / (5-1) = 125
Step 3: standard deviation = √(variance) = √125 = 5√5 (about 11.18)
The population of algae in an
experiment has been increasing by 40% each day. If there were 20 algae at the beginning of the experiment, predict the number of algae in 7 days.
First, complete the equation:
Future Amount = [?](1+[]0
The equation is y = 20(1.40)^x
where x is the number of days and y is the future amount after x days go by
The 1.40 is from the fact that 1+r = 1+0.40 = 1.40, where r is the decimal form of 40%, so r = 0.40
-----------------------------
Plug in x = 7 to get
y = 20(1.40)^x
y = 20(1.40)^7
y = 210.827008
y = 211
We round to the nearest whole number since it doesn't make much sense to have a fractional portion of an algae. After 7 days, there are about 211 algae.
you are installing a support wire for an electrical pole. the pole is 25 feet and the ground connection is 10 feet from the base of the pole. the wire is sold per whole feet. how many feet of support why should you purchase

divide 10kg in the ratio of 13 : 7
Answer:
6.5 : 3.5
Step-by-step explanation:
So to do this sum;
First, add both 13 and 7 which is 20
Then, 13/20 *10 = 6.5
and 7/20 *10 = 3.5
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Equal quotients correspond to equal ratios.
Taking the square root of a number is the *blank * Of squaring a number
Answer:
Opposite
Step-by-step explanation:
They are complete opposites:
When you take the square root of a number, you are taking the number to the 1/2 power. For example, the square root of 9 is 3.
When you square a number, you multiply it by itself. For example, 3 squared is 9.
So, these are opposites because when doing these operations to the same number, the products will be "opposites" of each other, like the examples above.

[tex] \boxed{ \bold{ \huge {\boxed{ \sf{ \frac{25}{2} }}}}}[/tex]
Step-by-step explanation:
[tex] \sf{5 \div \frac{2}{5} }[/tex]
When any number of fraction is divided by a fraction , we multiply the dividend by reciprocal of the divisor.
We can obtain the reciprocal of any fraction by interchanging the position of numerator and denominator.
⇒[tex] \sf{5 \times \frac{5}{2} }[/tex]
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator.
⇒[tex] \sf{ \frac{5 \times 5}{2} }[/tex]
Multiply the numbers : 5 and 5
⇒[tex] \sf{ \frac{25}{2} }[/tex]

=> 9x = 2
=> x = 2/9
Solve the system of linear equations in two variables by elimination or substitution.
2x + 4y = 4
2x - y=1
Answer:
x = 0.8 y = 0.6
Step-by-step explanation:
Solve one of the equations for a single variable, I chose the 2nd equation and solved for the variable y and I got y = 2x -1.
Next plug in the value for y into the 1st equation, I got :
2x + 4 ( 2x - 1) = 4
Next solve for x by first distributing the 4 to the (2x-1), this becomes (8x -4) then add like terms and move the -4 to the other side of the equation by addition. I got 10x =8 then I divided 8/10 to solve for x and I got 0.8.
Now plug the value 0.8 in for x in the 2nd equation : 2*(0.8) - y = 1
Then solve for y by subtracting 2*(0.8) or 1.6 from 1 and I got -0.6, lastly divide by -1 to solve for y.
I don't get this at all can you pls help me?

The are of a rectangle is 50m^2 , the length is 100m . Calculate the width
w = 0.5 m
Step-by-step explanation:A = l × w
50m² = 100m × w
w = 50m²/100m
w = 0.5 m
Answer:
The answer is 0.5 m i.e Width = 0.5 m
Step-by-step explanation:
Given,
Area (A) = [tex]50m^{2}[/tex]
length (l) =100 m
width ( b ) = ?
Now,
A = l * b
or, 50 = 100 * b
or, [tex]\frac{50}{100}[/tex]= b
or, b = 0.5 m

What is the solution to the equation 3x – 8 = -2?
O A. -3 1/3
O B. 3 1/3
C. 2
D. -2
Answer:
option (c) 2
Step-by-step explanation:
We have the linear equation :-
→ 3x - 8 = -2
add 8 both sides
→ 3x - 8 + 8 = -2 + 8
→ 3x = 6
→ x = 6 ÷ 3
→ x = 2
A store sells three varieties of cheese cheddar, Gouda, and Swiss. Each variety of cheese is available in two different styles shredded or sliced. How many possible outcomes for the variety and style of cheese are there?
Answer:
6 possible outcomes
Step-by-step explanation:
To solve this problem, we have to make use of the Fundamental Counting Principle formula.
The formula counting principle states that when we are given two or more distinct events, in order to get the total number of possible outcomes, we multiply such events together.
In the above question, we are given two events.
Event 1
3 varieties of cheese: Cheddar, Gouda, and Swiss.
Event 2
2 styles of cheese: Shredded and Sliced
The possible outcomes for the variety and style of cheese = Event 1 × Event 2
= 3 × 2
6 possible outcomes.
These 6 Possible outcomes are listed below:
1) Cheddar cheese , Shredded
2) Cheddar cheese , Sliced
3) Gouda cheese , Shredded
4) Gouda cheese , Sliced
5) Swiss cheese , Shredded
6) Swiss cheese , Sliced

Step-by-step explanation:
the presence of a segment bisected will result in what type of segments?
A: noncoplanar segments
B. parallel segments
C. congruent segments
D. perpendicular segments
first person to get it right will get brainliest
Answer:
Option C → Congruent segments
Step-by-step explanation:
The meaning of segment bisector is a segment which divides another segment into two equal parts.It is not necessary that the segement which is bisecting the another segment are perpendicular with one another.
So, when a segment is bisected the two segments are equal.
Equal means the two segments are congruent.
Most appropriate statement
Answer:
Congruent.
Step-by-step explanation:
Bisecting will give 2 segments of equal length.
