Find two numbers whose sum is 21 and their product is 104.
( Make sure you explain how you got the two numbers.
Show both equations as well )

Answers

Answer 1

Answer:

13x8=104     13+8=21    

Step-by-step explanation:

Hope this helps!

Answer 2
13•8=104. 13+8=21. To be honest I just used process of elimination. You can do this by listing the factors of 104, which are 1 & 104, 2 &52, 4 & 26, and 8 & 13. Then you add the pairs. 104+1=105, 105 does not equal 21. 52+2=54, 54 does not equal 21. 26+4=30, 30 does not equal 21. This means the answer has to be 13 & 8 because 13+8=21, and 21 is equal to 21.

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

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.

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.

please help me out with this problem, i'd really appreciate it

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

What is the greatest common factor of 52 and 78? Explain the method you used to find it.

Answers

The GCF of 52 and 78 is 26. To calculate the GCF of 52 and 78, we need to factor each number (factors of 52 = 1, 2, 4, 13, 26, 52; factors of 78 = 1, 2, 3, 6, 13, 26, 39, 78) and choose the greatest factor that exactly divides both 52 and 78
The greatest common factor is 26
