C. 30.4 feet

D. 38 feet

Answer: You answer is going to be C. 30.4

Answer: 7.6 / 1

x / 4

x = 7.6 * 4

x = 30.4

Therefore the answer is C I believe.

x / 4

x = 7.6 * 4

x = 30.4

Therefore the answer is C I believe.

It cost $.06 per local call and $0.15 per international call you are charged $69.84 and your calls add up to 852 minutes write and solve a system of linear equations

Answer: the number of minutes of local calls that you made is 644

the number of minutes of international calls that you made is 208

Step-by-step explanation:

Let x represent the number of minutes of local calls that you made.

Let y represent the number of minutes of international calls that you made.

It cost $.06 per local call and $0.15 per international call you are charged $69.84. This means that

0.06x + 0.15y = 69.84 - - - - - - - - 1

The total number of calls add up to 852 minutes. This means that

x + y = 852

Substituting x = 852 - y into equation 1, it becomes

0.06(852 - y) + 0.15y = 69.84

51.12 - 0.06y + 0.15y = 69.84

- 0.06y + 0.15y = 69.84 - 51.12

0.09y = 18.72

y = 18.72/0.09 = 208

x = 852 - y = 852 - 208

x = 644

What is the answer of 2/3 time 1

The answer will still be 2/3 because you * it by 1

The answer would still be 2/3 because anything multiplied by 1 equals that number

What is 86 divided by 34 , and what is 96x34

86/34=2.52 and 96x34=3264. :)

86 divided by 34=2.529

96×34=3264 :))

96×34=3264 :))

Two angles are supplementary. If one of these angles measures 50 degrees more than the other, find the measure of the smaller angle.

X= small angle x+50= larger angle supplementary angles=180 degrees x+x+50= 180 combine like terms 2x+50=180 subtract 50 2x= 130 divide by 2 x= 65 degrees for the smaller angle 115 degrees for the larger hope this helps

Which equation correctly applies the distributiveWhich equation correctly applies the distributive property? 1 . (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) 2.−1.2⋅0.57⋅0.5=−1.2⋅0.5⋅0.57 3. 50+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005) 4. −2.5⋅(4⋅1.045)=(−2.5⋅4)⋅1.045 property?

Number 4 because distributive property has parentheses

Through slow on land the leather back turtle holds the record for the fastest water speed of any reptile. The largest leather back yet discovered could swim at a speed of 9. 78 m/s. If it's KE was 60, 800. 0J, what's the mass

Answer: 1271.32 kg

Step-by-step explanation:

Given: The speed of turtle with largest leather back= 9.78 m/s

It's Kinetic energy = 60800 joules

We know that with mass 'm' and speed 'v', the formula kinetic energy is given by

Hence, the mass of turtle= 1271.32 kg
