80% of 120 is what value? 20 40 96 108

Answers

To calculate 80% of 120, you simply multiply 120 by 0.80 (which is the decimal representation of 80%).

80% of 120 = 0.80 * 120 = 96.

So, the correct answer is 96.

Ordered pairs in which of these formats would always represent a function?A.(number of months since birth,age in years)
B.(height,age)
C.(age,weight)
D.(age,grade in school)

Answers

basically, the same first number repeats with a differnet second number

A. number of months always changes so it will never repeat, ths is a function
B. you can grow shorter somehow so heights could be repeated or you could never grow
C. age always goes up, but you could be different weights in the same age so this isnt' a function
D. same as last, you could change grades in the same year



A is ansre

Answer:

C. (age, weight)

My answer isn't verified or anything, but I do believe it to be correct.

A dartboard consists of two concentric circles. The probability of hitting the inner circle is64%. If the outer circle has a diameter of 20 inches, what is the radius of the inner circle?

2 inches
4 inches
8 inches
16 inch

Answers

Given:
Diameter of outer circle = 20 inches.

We need to find the Area of the outer circle to get the radius of the inner circle.

Area = πr²

Outer circle Area = 3.14 * (10in)² = 314 in²

314 in² * 64% probability = 200.96 in² Area of the inner circle.

200.96 in² = 3.14 * r²
200.96 in² / 3.14 = r²
64 in² = r²
√64 in² = √r²
8 in = r

radius of inner circle is 8 inches.

X + 1.5x - 0.75 = 73

what is the value of x?

Answers

x + 1.5x - 0.75 = 73
2.5x - 0.75 = 73
2.5x = 73 + 0.75
2.5x = 73.75
x = 29.5

The answer is: x = 29.5.

Use integers to calculate and represent the balloons total change in altitude. Math symbols Relations Geometry Groups Trigonometry Statistics Greek Previous Next

Answers

The total change in altitude= 960ft.

Step-by-step explanation:

Rate at which balloon descend = 320 ft per minute

Time = 3 mins

Total height descended = 320 x 3

= 960 ft.

The total change in altitude= 960ft.

Whats 1/5 divided by 5

Answers

1/5 ÷ 5 
when a fraction is being divided by a number you multiply the first number by the reciprocal of the second number. A reciprocal is basically a number that can be multiplied by the first number to make 1
So in this case the reciprocal of 5 is 1/5
now just multiply and get 1/25
So the answer is 1/25
First, we have to make sure both numbers are fractions.
The first number is already a fraction; make the second whole number into a fraction.

5 as a fraction is (5)/(1).

Now follow these steps:
Rewrite equation.
Switch division sign to multiplication.
Find reciprocal of the second fraction, which means to flip the fraction around.
Cross multiply.
Simplify if needed.

Now let's put that into this equation.

(1)/(5)/ (5)/(1)\n \n(1)/(5) * (5)/(1) \n \n (1)/(5) * \frac {1}{5} \n \n 1*1=1\n4*5=25 \n \n (1)/(25)
