Petra jogs 2 miles in 24 mins. at this rate how long would it take her to jog 7 miles?
Wewaii [24]
The answer would be 84 because 2miles is equal to 24 minutes so you would break that in half down to one mile. One mile would be 12 minutes. So you would multiply 12 times 7 which equals 84 which would be your answer.

Given -16 = m over 5 -18; prove m=10
Aleks04 [339]

- 16 =  \frac{m}{5}  - 18 \\  =  >  - 16 =  \frac{m - 18 \times 5}{5}  \\  =  >  -16 \times 5 = m - 90 \\  =  >  - 80 = m - 90 \\  =  >  - 80 + 90 = m \\  =  > 10 = m \\  =  > m = 10
Hence provided

Pi High school ordered 40 science books. The next week, the school ordered 30 algebra books. The bill for the first order was $3
Darina [25.2K]
40s=360+30a
40s+30a=$3960

40s=360+30a
40s/40=360+30a/40
s = 9+3/4a

40(9+3/4a) +30a=$3960
360+30a+30a=$3960
360+60a=$3960
360-360+60a=$3960
60a=$3960
60a/60 = $3960/60
a= $60
The algebra book is $60

Find the smallest zero for the function h(x)=4x^2-8x-60.
ankoles [38]
H(x) = 4x² - 8x - 60
    0 = 4x² - 8x - 60
    0 = 4(x²) - 4(2x) - 4(15)
    0 = 4(x² - 2x - 15)
    4               4
    0 = x² - 2x - 15
    0 = x² - 5x + 3x - 15
    0 = x(x) - x(5) + 3(x) - 3(5)
    0 = x(x - 5) + 3(x - 5)
    0 = (x + 3)(x - 5)
    0 = x + 3    or    0 = x - 5
  - 3        - 3        + 5      + 5
    3 = x       or       5 = x

A circle with radius of 6 cm sits inside a circle with radius of 9 cm.
taurus [48]

Answer:

Equation for the area of a circle- π r²

The 2 radiuses are 6 and 9.

6 squared is 36 and 9 squared is 81.

The smaller one is 36π and the larger one is 81π.

The difference between them is the area of the shaded region.

81π - 36π = 45π

Use 3.14 for π.

45 x 3.14 = 141.3 u²

Hope this helps!
