Susan drove 571 miles and the trip took 14 hours of driving time she wants to shorten her driving time by 1/2 hour what average
Allushta [10]

Answer: The answer is 80 mph.


Step-by-step explanation: 1. Divide 14 from 571.

2. You'll get the answer 40. So it's 40 mph.

3. If she's trying to shorten by 1/2 then she should drive 80 mph because if you drive 80 mph it will take 7 hours instead of 14 hours. (She'll go 7 hours because you divide 14 hours by 2. Then you have to multiply 2 to 40.)

Meg dilated triangle W by a factor less than 1. Then she performed other transformations that were not dilations to create simil
ankoles [38]

Answer:

A. <em>X</em>(–2, 2), <em>Y</em>(–10, 2), <em>Z</em>(–6, 10)

Step-by-step explanation:

This looks a bit tough, but knowing that scale factors less than 1 are ½, ¼, etcetera, I come to this answer, also knowing that in the end, they must have an unproportional relationship.

I hope this is correct, and as always, I am joyous to assist anyone at anytime.

The sum of angles 7 and 8 is 180, so to find angle 8 you would subtract angle 7 from 180. So:

180 - 92 = 88  

The answer is B, 88 degrees.

The height of a triangle is 7 ft more than its base. If the area of the triangle is 30 ft2, what is the length of the base?
SSSSS [86.1K]

Answer:

see below

Step-by-step explanation:  5 27  7  16

area = 1/2 bh

height of a triangle is 7 ft more than its base

base = b

height = b + 7

area = 30

area = 1/2 b(h)

30 = 1/2 b(b + 7)

30 = 0.5(b²+ 7b)

30 = 1/2 b²+ 3.5b           solve for b

1/2 b²+ 3.5b = 30        

1/2 b²+ 3.5b - 30 = 0        

b²+ 7b - 60 = 0            factor

   (b +12)(b - 5) = 0    when b = -12 or 5     base length can't be negative

b = base = 5

area = 1/2 bh     1/2×2(9)     = 9

area = 1/2 bh     1/2×5(12)     = 60

area = 1/2 bh     1/2×9(16)     = 56

area = 1/2 bh     1/2×12(19)     = 114

For a given function f(x), the domain is (-[infinity],-2] and the range is (5,[infinity]). What is the correct domain and range
Serga [27]

Answer:

Domain of the inverse is (5, infinity)

Range of the inverse is (-infinity , -2)

Step-by-step explanation:

To find the domain of the inverse function, we have that;

The range of the function becomes the domain of the inverse

The domain of the function becomes the range of its inverse

so the domain is (5, infinity)

range is (-infinity, -2)
