= 2^2×4

=2^8

evaluated :

2^8 = 2×2×2×2×2×2×2×2 = 256

Answer:

2^8, 256

Step-by-step explanation:

(2^2)^4, 2*4=8, 2^8

2*2*2*2*2*2*2*2=256

The fraction of the cars that are less than 3 years old also get 30 miles to the gallon is 13/30.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Of the cars in a used-car lot, 23 are less than 3 years old and 13 of the cars on the lot are both less than 3 years old and also get at least 30 miles to the gallon.

Therefore, The fraction of cars that are less than 3 years old also get 30 miles to the gallon is simply 13/23.

Answer:

Step-by-step explanation:

let amount of nickels = y

then amount of quarters = 12-y

let amount of dimes = 2y

according to given condition,

Total amount = y+12-y+2y

we will +y and -y because of different signs,(+,- = -).

10.60 = 12+2y

12-10.60 = 2y

2.60=2y

using / as division sign,

y=2.60/2

y = 1.30

amount of quarters = 1.30

amount of nickels = 12-y

                              = 12-1.30

                            = 10.70  

amount of dimes =  2y

                              =2(1.30)

                               =2.60

The measure of the exterior angle to ∠D will be 137°.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In triangle DEF,

m ∠D = (4x + 15)°, m ∠E = (5x + 32)°, and m ∠F = 70°

Now,

Sum of the measure of angle in a triangle is 180°.

So, We can formulate;

⇒ m ∠D + m ∠E + m ∠F  = 180°

Substitute all the values, we get;

⇒ (4x + 15) + (5x + 32) + 70 = 180

⇒ 9x + 117 = 180

⇒ 9x = 180 - 117

⇒ 9x = 63

⇒ x = 7

Thus, We get;

m ∠D = (4x + 15)°

m ∠D = (4 x 7 + 15)°

m ∠D = (28 + 15)°

m ∠D = (43)°

And, m ∠E = (5x + 32)°

m ∠E = (5 x 7 + 32)°

m ∠E = (35 + 32)°

m ∠E = 67°

Since, The measure of the exterior angle to ∠D = m ∠E + m ∠F

                                                                          = 67° + 70°

                                                                          = 137°

Thus, The measure of the exterior angle to ∠D will be 137°.
