Answer:

68.6

Step-by-step explanation:

Given the initial ratio of 24 points out of 35 possible points, you can set up a proportion (equivalent ratios) to find the expected number of points math students would ear on a test of 100 possible points:

\frac{earned}{possible}=\frac{24}{35}=\frac{x}{100}

Where 'x' is the number of points earned on the 100 point test.

Cross-multiply: 35x = 24(100) or 35x = 2400

Divide both sides by 35: 35x/35 = 2400/35

Solve for x:  x = 68.6

The surface area of a rectangular prism is 208 cm2. Two of the dimensions are 2cm and 10cm. Find the measure of the other dimens
aliina [53]

Answer:

7 cm

Step-by-step explanation:

SA = 208 cm^2

SA= 2*a*b + 2*a*c + 2*b*c

where:

a= first dimension = 2 cm

b= second dimension = 10 cm

c= third dimension

so we have:

208= 2*2*10 + 2*2*c + 2*10*c

208= 40 + 4c + 20c

208-40= 24c

168=24c

c =168/24

c = 7cm = third dimension
