Answer:
-5/2
Step-by-step explanation:
for perpendicularity;
[tex]m1 = \frac{ - 1}{m2} [/tex]
where m1 is first slope
and m2 is second slope
so here, let m1 be green line slope
and m2 be red line slope
thus,
[tex]m2 = \frac{ - 1}{m1} [/tex]
[tex]m2 = \frac{ - 1}{ \frac{2}{5} } = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} = \frac{ - 5}{2} [/tex]
40x divided by 10=28
Answer:
x = 7
Step-by-step explanation:
40x ÷ 10 = 28
40x ÷ 10 × 10 = 28 × 10
40x = 280
40x ÷ 40 = 280 ÷ 40
x = 7
Answer:
x=7
Step-by-step explanation:
40x/10 = 28
40x/10 * 10 = 28 *10
40x= 280
40x/40 = 280/40
x = 7

Which of the following transformations will always produce a congruent figure?
A. reflection
B. dilation
C. expansion
D. contraction
Which of the following transformations will produce a similar, but not congruent figure?
A. dilation
B. translation
C. reflection
D. rotation
Answer:
A, d
Step-by-step explanation:
A) reflection, A) dilation
Step-by-step explanation:
To produce a congruent figure, the angle measures of the image and the side lengths of the image must be the same as the angle measures and side lengths of the pre-image. This means we cannot shrink, expand, or contract the figure; by definition, those transformations change the size. This leaves reflection.
To produce a similar, but no congruent figure, we must change the side lengths while keeping the angle measures preserved. Translations, reflections and rotations will move a figure but do not change the side lengths; dilation is the only choice that will change the side lengths.

Gianah lives in Milton. She bought a bus ticket to travel to her cousin's house in Orlando. She gets on the bus in Mobile. The distance between the two cities is 300 kilometers and the bus drives 70 kilometers per hour. If the bus is 30 kilometers away from Orlando.
Answer: A. 300 - 70h = 30
Step-by-step explanation:
Rest of the question is:
Which of these following equations represents the hours, h, the bus has travelled.
The driver is going at 70 kilometers per hour meaning that for every hour that passes, 70km has been traveled. Expression to find the distance travelled given hours is:
= 70h
There are 300km between the two cities and 30km are left in the journey. Expression is therefore:
300 - 70h = 30
This shows that when you find the distance travelled so far and deduct it from 300, you will get 30km.
The equation that can represent the distance for which the bus has travelled is 300-70h=30.
What is Speed?The speed can be defined as the rate of change of position of an object with respect to time. It is given by the formula,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
The distance travelled by bus is 270 kilometers (300-30), because the distance left between the bus and Orlando is 30 kilometers. while the speed of the bus is 70 kmph.
Let the time for which the bus travelled be h, therefore, the equation that can represent the hours for which the bus has travelled is,
Total distance - distance covered in h hours = distance left between bus and Orlando
[tex]300-70h=30[/tex]
Thus, the equation that can represent the distance for which the bus has travelled is 300-70h=30.

Answer:
number 5:4/12
#6: 25/45
#7: 26/44
#8: 52/30
Step-by-step explanation:
Answer:
5) 1/3=x/12
12=3x
3x=12 (divide both sides)
12 divided by 3 = 4
therefore, x = 4
6) 5/9=25/y (cross multiply the numbers)
after cross multiplying you should get: 5y=225
divide both sides to get 45
therefore, y = 45
7) 26/z = 13/22 (cross multiply numbers)
after cross multiplying, you should get: 572=13z (swap the numbers)
after swapping the number, you should get: 13z=572 (divide both sides)
after dividing you should get 44
therefore, z = 44
8) b/30 = 2.6/1.5 (simplify expression)
after simplifying you should get: b/30=26/15 (cross multiply after)
after cross multiplying you should get: 15b = 780 (divide both sides)
after dividing both sides, you should get: 52
therefore, b = 52
Hope this helps:)!

Answer:
B
Step-by-step explanation:
The numbers in each of the circle halves are all in the blue side therefore all numbers on the red side would be eliminated. Leaving you with the options of B or C.
Now the Blue side for every pair is facing each other. So C would be eliminated because the red side is facing the start of the second pair ( A.K.A the third circle)
Leaving us with B.
