Answers

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°

What is the relationship between the figure number in the number of stars in the figure represents the relationship in as many ways as possible.

Answers

Answer:

It is the the figure numbers squared and then +1 added to it.

So Fig. 1 is 1^2 +1 = 2

Fig 2 is 2^2 +1

Fig 3 is 3^2 + 1

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°.

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

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.
