Answer: 77 : 144 or 77/144
Step-by-step explanation:
First find the total number of people for each school.
Wood Middle School : 136 + 172 = 308
Parker Middle School: 312 + 264 = 576
The ratio of students at Wood school to students at Parker Middle School is
308 : 576 = 77 : 144 or 77/144
Answer:
Step-by-step explanation:
Area if a traiangle =1/2 × base × height
5 1/10 = 1/2 ×3 2/5 ×h
Change mixed fractions to improper fractions
51/10= 1/2 ×17/5 ×h
51/10 = 17/10×h
Divide 51/10 by the coefficient of h
51/10÷17/5 = h
51/10 ×5/17 = h
3/2 = h
h =1 1/2 inchea
The height of the triangle 1 1/2 inches
Answer:
x = 5
Step-by-step explanation:
9/15 = 3/x
x = 5
Answer:
y = 2x
Step-by-step explanation:
Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:
1 present wrapped -> 2 centimeters of tape
x presents wrapped -> y centimeters of tape
1/x = 2/y
x = y/2 -> y = 2x
From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.
The slope is y=3x-2, or if you had to rewrite it, 3x-2 is the slope. The y intercept could be found using the previous formula, y=3x-2. If x were to be equal to 5 for example, you would have to multiply that by 3, then subtract it by 2, and you get your y intercept, which would equal 13 (THIS IS AN EXAMPLE).
