Answer 1

Step-by-step explanation:

9. x°=90°-30°=60°

10. x°=180°-(40°+65°)=180°-105°=75°

11. x°=180°-(35°+45°)=180°-80°=100°

12. x°=180°-(25°+x°+65°)

x°=180°-90°-x°

2x°=90°

x°=45°; (x+65)°=110°

13. x°=180°-(48°+x°-44°)

x°=180°-4°-x°

2x°=176°

x°=88°; (x-44)°=44°

14. x°=180°-(73°+x°-11°)

x°=180°-62°-x°

2x°=118°

x°=59°; (x-11)°=48°

A bakery has 72 half gallons of milk.
It takes 1 2/3 cups of milk to make a cake. Note that 1 cup = 1/8 half gallon = 0.125 half gallon. How many cakes can the bakery make? Say 1,2,3,4 in your answer so that I know which option to choose. There’s no 346 option (a lot of people have been saying that answer.)

Answers

Answer:

345 :)

Step-by-step explanation:

Bakery can make 576 cakes.
Explanation:
Amount of milk in bakery = 72 half gallon
Amount of milk needed to make cake =
1 2/3 = 1*3+2/3 = 5/3 cups.
1 cup = 1/8 half gallon = 0.125 half gallon.
Amount of milk need to make cake=
0.125* 5/3 = 0.208
half gallon.
Total cake made in bakery = 72/0.208 =
346 cakes.
So bakery can make 346 cakes.

Answers

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

Answers

The answer to the question would be 10 because 23-13=10 and they wanting to know how many will also be 30 miles too.

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

What is a fraction?

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.

In triangle DEF, m∠D = (4x + 15)°, m∠E = (5x + 32)°, and m∠F = 70°. Determine the degree measure of the exterior angle to ∠D.

137°
113°
67°
43°

Answers

D) 67° is the answer

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°.
