Mathematics

Helga [31]4 years ago
3 0

Answer:

88

Step-by-step explanation:

Let's see - if there are 3/5 girls, there must be 2/5 boys. Assuming everyone in the class is binary, of course.

So 2/5 of 220 is the number of boys. When you see "of," always think multiplication!

2/5 of 220

2/5 * 220 = 88 boys in 7th grade

In Triangle ABC, AC is extended through C to D. If
DENIUS [597]

Answer:

X  = 5 unit

Step-by-step explanation:

Given as , ABC is a Triangle ,

AC extended to through C to D

∠BAC = 6x + 10

∠ABC = 6x - 10

∠BCD = ∠ 8x + 20

When c extended to D then , ∠BCD is an external angle

∵ <u>External angle = Sum of opposite internal angles</u>

Or ,∠BCD = ∠BAC + ∠ABC

Or, ∠ 8x + 20 = 6x + 10 + 6x - 10

Or, ∠ 8x + 20 = 12x

Or, 12x - 8x = 20

∴ 4x = 20

So, x = \frac{20}{4} = 5

Hence the value of X = 5  unit  Answer

Denise wants to burn at least 5000 calories a week through running. Based on her running speed, she estimates that she can burn
Firdavs [7]

Answer:

She will not meet her goal.

Step-by-step explanation:

There are 5 weekdays, so she will run for 0.5 * 5 = 2.5 hours over the weekdays

There are 2 weekends, so she will run for 2 * 1 = 2 hours over the weekend.

In total, this means she will run for 4.5 hours.

4.5 hours * 550 calories per hour = 2475 calories.

She will not meet her goal.
