Answer:

175 dimes and 75 quarters

Step-by-step explanation:

Make a system of equations, where d is the number of dimes and q is the number of quarters:

d + q = 250

0.1d + 0.25q = 36.25

Solve by elimination by multiplying the top equation by -0.1:

-0.1d - 0.1q = -25

0.1d + 0.25q = 36.25

0.15q = 11.25

q = 75

Then, plug in 75 as q into one of the equations to solve for d:

d + q = 250

d + 75 = 250

d = 175

So, there are 175 dimes and 75 quarters

students were grouped into 4 classrooms with an average of 33.5 students per classroom. if the students were regrouped into 5 cl
erma4kov [3.2K]

Answer:

26.8

Step-by-step explanation:

Because 33.5 was the average of how many students were in a classroom (if there were 4 classrooms), then 33.5 is can somewhat be the average of how many students were in one classroom; 1/4 of the classrooms can hold an average of 33.5.

Total students that were divided into 4 classrooms :

33.5 × 4 = 134

So if there is 134 students that will be grouped into 5 different classrooms, divide 134 by 5 to find the average amount of students that will be grouped.

134 ÷ 5 = 26.8

So, the average amount of students that will be grouped if they were divided into 5 classrooms would be 26.8 .

Hope this helped !

(-1,-6) and (-3,-8) y=Mx+b
denpristay [2]

Answer:

m = 1, b = -5         y = x -5

Step-by-step explanation:

first find the slope or m

slope is change in y over change in x

-8 - (-6) = -2

-3 - (-1) = -2

-2/-2 = 1

m = 1

y = x + b

use one of the points and solve for b

QUICK <br><br> PLZ HELP ME UNDERSTNSD
alex41 [277]

Answer: 37.05m^2

Step-by-step explanation:

Area of shaded region = Area of rectangle - non shaded region (the middle shapes)

Rectangle = 13.7 x 14.4 = 197.28m^2

Left half circle: 3.14 x 6.3^2 = 124.6266m^2

Right half circle: 3.14 x 2.8^2 = 24.6176m^2

Square: 3.3^2 = 10.98 m^2

197.28 - ( 124.63 + 24.62 +10.98 ) = 37.05 m^2
