Answer:

Step-by-step explanation:

Angles in a triangle add up to equal 180

So 65 + 57 + ? must equal 180

Solve for ?

65 + 57 + ? = 180

Combine like terms

122 + ? = 180

Subtract 122 from both sides

122 - 122 + ? = 180 - 122

? = 58

Answer:

The cost of the candy is

$5 for strawberry taffy and

$4 for banana taffy

Step-by-step explanation:

Here we have

Let the strawberry taffy be = S and

the banana taffy = B

The system of equation becomes

4·S + 6·B = $44......................(1)

2·S + 5·B =$30.......................(2)

To solve the equations, we multiply equation (2) by 2 to get

2×(2·S + 5·B) =$30. × 2

4·S +10·B = $60.......................(3)

We subtract equation (1) from equation (3) to get

(4·S +10·B)-(4·S + 6·B) = $60 - $44

4·B = $16 or B = $16/4 = $4

Therefore, from equation (2) we have

2·S + 5×$4 =$30 or

2·S = $30 - $20 = $10

S = $10/2 = $5

The candy costs

Strawberry taffy = $5 and

Banana taffy = $4

Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was

Marizza181 [45]

Answer:

The raw score for his exam grade is 99.69.

Step-by-step explanation:

Given : The professor announced that the mean for the class final exam was 88 with a standard deviation of 7. Given Daniel's z score of 1.67.

To find : What is the raw score for his exam grade?

Solution :

The formula use to find the z-score is

$z=\dfrac{x-\mu}{\sigma}$

Where, z=1.67 is the z-score

$\mu=88$ is the means

$\sigma=7$ is the standard deviation

x is the raw score for his exam grade

Substitute the values,

$1.67=\dfrac{x-88}{7}$

$1.67\times 7=x-88$

$11.69=x-88$

$x=88+11.69$

$x=99.69$

Therefore, the raw score for his exam grade is 99.69.

How do you solve for a missing component x ? 180:x::12:24

VMariaS [17]

So, what it is saying in words is 180 is to x as 12 is to 24. So, determine what relates the second half of the problem, which would be 12 is half of 24. Therefore, 12 times 2 is 24. So, x is 360 because 180 times two is 360.
