A 90° counterclockwise rotation about the origin, and then a reflection across the x-axis performed on shape I proves that shape II is congruent to shape I. Which other sequences of transformations on shape I can also be used to prove congruence to shape II? a reflection across the y-axis and a 90° clockwise rotation about the origin a 90° counterclockwise rotation about the origin and a reflection across the y-axis a reflection across the y-axis and a 90° counterclockwise rotation about the origin a 90° clockwise rotation about the origin and a reflection across the x-axis a reflection across the x-axis and a 90° clockwise rotation about the origin select ALL the correct answers ↑
Answer:
a 90° clockwise rotation about the origin and a reflection across the x-axis
Step-by-step explanation:
A 90° counterclockwise rotation about the origin means a right angle about the origin in opposite direction the needle would point to (9=45 mins)the reflection of it would mean the needle is at 3 = 15 min
Yes shape I is congruent to shape II because on both shape the needle lies on the x- axis.
a reflection across the y-axis and a 90° clockwise rotation about the origin
No because at one end the needle is at 3 and at the other the needle is at 9 giving a difference of negative and positive quadrantsa 90° counterclockwise rotation about the origin and a reflection across the y-axis
No because at one end the needle is at 9 and at the other the needle is at 3 giving a difference of negative and positive quadrantsa 90° counterclockwise rotation about the origin
It shows 3/4 of the spherea 90° clockwise rotation about the origin and a reflection across the x-axis
Yes because the needle lies on the x- axis at both endsa 90° clockwise rotation about the origin
It shows 1/4 of the sphere.Answer:
answer is C and E

A grocery store sells a store-made brand of raisin bran in bulk (by the pound). The store sells this mixture for $3.14 per pound. When the store mixes its raisin bran, the employees use raisins that are $4.50 per pound and bran flakes that are $2.80 per pound. If the store makes 50 pounds of raisin bran, how many pounds or raisins and bran flakes does the store need?
Answer: quantity of raisins = 10 pounds, quantity of bran flakes = 40pounds.
Step-by-step explanation:
Let r= quantity of raisins, b = quantity of bran flakes.
As per given,
r+b=50 (i)
4.50r + 2.80b= 3.14(50)
⇒4.50r + 2.80b=157 (ii)
Multiply (i) by 2.80, we get
2.80r+2.80b=140 (iii)
Now, subtract (iii) from (ii), we get
1.7r = 17
⇒ r= 10
Put this in (1), we get
[tex]10+b=50\Rightarrow\ b= 40[/tex]
Hence, quantity of raisins = 10 pounds, quantity of bran flakes = 40pounds.
When f(x)= -2x + 6, what is f(-x + 3)?
A. 2x + 1
B. 2x
C. 2x + 9
D. 2x2^2 -6x + 6
Answer:
B. 2x
Step-by-step explanation:
f(x) = -2x + 6
f(-x + 3)
f(-x + 3) = -2(-x+3) + 6
f(-x + 3) = 2x - 6 + 6
f(-x + 3) = 2x

A police car drives at a constant speed of 108 km/h. How long will it take to travel a distance of
378 kilometers?
Answer:
3 hours 50 minutes
Step-by-step explanation:
since speed equals distance multiplied by the time taken, using the same formula time taken will be the distance divided by the speed. so 378kilometres divided by the 108 kmper hour you get the answer 3 hours 50 minutes
Find the distance you travelled if rate=12mph and time 4hours
Answer:
48 miles
Step-by-step explanation:
Answer:
48 miles
Step-by-step explanation:
Distance = Speed × Time
In this case the speed is 12 miles per hour and time is 4 hours
So:
Distance = 12 × 4
Distance = 48 miles

Answer:
x = 16, y = 10
Step-by-step explanation:
(8x - 14) and (5x + 34) are alternate exterior angles and congruent, thus
8x - 14 = 5x + 34 ( subtract 5x from both sides )
3x - 14 = 34 ( add 14 to both sides )
3x = 48 ( divide both sides by 3 )
x = 16
Then
8x - 14 = 8(16) - 14 = 128 - 14 = 114
(5y + 16) and (8x - 14) are adjacent angles and supplementary, thus
5y + 16 + 114 = 180 , that is
5y + 130 = 180 ( subtract 130 from both sides )
5y = 50 ( divide both sides by 5 )
y = 10
Write two rational numbers a/b and c/d, where a, b, c, and d are the digits 2, 3, 4, or 5, such that no digit can be used more than once and that the two rational numbers are the greatest distance apart on the number line. Explain how you got this answer.
Answer:
Following are the solution to this question:
Step-by-step explanation:
Let [tex]\frac{a}{b} \ \ and \ \ \frac{c}{d}[/tex] both are the rationalnumbers and for both numbers there is not a greatest distance. so, the value [tex]\frac{c}{d}[/tex] must have greatest for the value [tex]\frac{c}{d}[/tex] and the c is maximum and d is minimum.
if c= 5 and d=2
[tex]\to \frac{c}{d} = \frac{5}{2}=2.5[/tex]
Similarly:
[tex]\to \frac{a}{b}[/tex]
a=3 and b=4
[tex]\to \frac{a}{b}=\frac{3}{4} = 0.75[/tex]
so, the [tex]\frac{a}{b} \ \ and \ \ \frac{c}{d}[/tex] is at the great distance.

a deli charges 5 for a sandwich and 2 for a drink in one day the deli made 230 selling a total 55 sandwiches and drinks . how many drinks were sold at the deli that day
Answer: 15
Step-by-step explanation:
Let the number of sandwich sold be a
Let the number of drinks sold be b
The following can be formed as.an equation from the question:
5a + 2b = 230 ....... i
a + b = 55 ....... ii
Multiply equation i by 1
Multiply equation ii by 5
5a + 2b = 230 ........ iii
5a + 5b = 275 ........ iv
Subtract iv from iii
-3b = -45
b = 45/3
b = 15
The number of drinks sold were 15

Step-by-step explanation:
We are going to solve the system by subtracting one equation from another in this case the second from the first.
Now we are going to divide 30 by 6 which will give you the value of x.
Now we will substitute x into one of the equations to solve for y.
Now we multiplied 6 by 5.
Now we will subtract 30 from 60 giving you the value of 2y.
Now you divide 30 by 2 giving you the value of y.
Now check you answers by inserting the values you got for x and y into one of the original .

Body shape, like a circle for each grey hippo instead a pumpkin shape for the blue-gray one
Answer:
1: A because the proportions are off
2: yes, since the second and third hippos are both 4 feet tall, however one of them looks different. we know that the first and last hippos are not distorted because their proportions are equal, but the second one is much wider with a very different body shape, and looking at the original, we can easily tell that the ratio is incorrect. also, the color is very different from the original.

Hector solves and equation by subtracting 8 from both sides of the equation. Then he multiples both sides of the equation by 3. The result is m=15. What was the original equation? How do you know?
Given:
The result is [tex]m=15[/tex].
To find:
The original equation.
Solution:
We need to apply the opposite operations from bottom to top in the resultant equation to get the original equation.
It means opposite operation of last operation will be applied first.
We have,
[tex]m=15[/tex]
Divide both sides by 3.
[tex]\dfrac{m}{3}=5[/tex]
Add 8 on both sides.
[tex]\dfrac{m}{3}+8=5+8[/tex]
[tex]\dfrac{m}{3}+8=13[/tex]
Therefore, the original equation is [tex]\dfrac{m}{3}+8=13[/tex].

Find the measures of the numbered angles in the following rectangle.
The measures of Angle 1 is 29 degrees, Angle 2 is 61 degrees, Angle 3 is 90 degrees, Angle 4 is 29 degrees, Angle 5 is 90 degrees.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
In the given figure there are two right angle triangles.
By angle sum property, the sum of three angles is 180 degrees.
Now let us find angle 4
61+angle 4=90
Angle 4=90-61
Angle 4 =29 degrees
Now let us find angle 1
Angle 5 is 90 degrees.
61+90+Angle 1= 180
151 + Angle 1=180
subtract 151 from both sides
Angle 1=180-151
Angle 1 is 29 degrees.
Now let us find angle 2
Angle 1+ Angle 2 =90
29+ Angle 2=90
Angle 2=90-29
Angle 2 is 61 degrees.
Angle 3 is 90 degrees.
Hence, the measures of Angle 1 is 29 degrees, Angle 2 is 61 degrees, Angle 3 is 90 degrees, Angle 4 is 29 degrees, Angle 5 is 90 degrees.

What is the equation in the slope-point form of the line that passes through the points (-5,-9) and (7,9) A. y - 9=1.5(x - 5) B. y + 9=1.5(x - 7) C. y - 5=1.5(x + 9) D. y - 9=1.5(x - 7)
Answer:
D. y - 9 = 1.5(x-7)
Step-by-step explanation:
First find the slope using this formula. y2-y1/x2-x1
Plug in with (-5, -9) & (7, 9)
9-(-9)/7-(-5) = 18/12 (simplify)
18/12 ÷ 3 = 6/4 ÷ 2 = 3/2
The slope is 3/2 or 1.5
To find the y-intercept plug in one of the points (7, 9)
9 = 3/2(7) + b (b represents the y-intercept)
9 = 10.5 + b
-1.5 = b
The equation is y = 1.5x - 1.5
A. y = 1.5x + 1.5
B. y = 1.5x - 19.5
I'll just skip C the answer is D I'll show the work
y - 9 = 1.5(x-7) (distribute 1.5 to x and -7)
y - 9 = 1.5x - 10.5 (add 9 on both sides)
y = 1.5x - 1.5
