The distance between him and school is 1.59 miles. Of course this distance is linear to make this problem simple. He walks with a speed of 3 miles per hour or 0.00083 mile per second.
To calculate time from distance and speed we use this formula: 
seconds. To convert minutes we divide number of second by 60. 
.
It will take him approximately 60 minutes to get to school.
Answer : B
Step by step: make it into two shapes by drawing a line through the shape which would be a square and a triangle. Area of square is bxh so 8x10=80
Area of triangle is 1/2(bxh) so 1/2(4x5)=10
80+10=90
Answer:
His goal wasn't mean't because percentage of grams from whole grains is 25% which is less than 30%
Step-by-step explanation:
Total grams of carbonhydrate = 220 grams
grams from whole grains = 55 grams
percentage amount of carbonhydrate from whole grains = 55/220 × 100 = 25%
Hence his goal wasn't mean't because percentage of grams from whole grains is less than 30%
Answer:
y=8.1
Step-by-step explanation:
F(x)......ur output = 19
19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0
2x + 7 = 0
2x = -7
x = -7/2
x - 2 = 0
x = 2
I believe there is 2 possible answers......x (ur input value) = -7/2 or 2
