In ΔSTU, s = 3.8 inches, t = 9.8 inches and u=9.6 inches. Find the measure of ∠U to the nearest 10th of a degree.

Answers

Answer 1

Answer:

m∠U = 75.7°

Step-by-step explanation:

use Law of Cosines:

9.6² = 3.8² + 9.8² - 2(3.8)(9.8)·cos U

92.16 = 14.44 + 96.04 - 74.48·cos U

92.16 = 110.48 - 74.48·cosU

-18.32 = -74.48·cosU

cos U = -18.32/-74.48

cos U = 0.24597

arccos U = 75.7

Answer 2

Answer:

m∠U = 75.7°

Step-by-step explanation:

its on delta and if you use a calculator then its m∠U = 75.7°

Answer:

C. 35 sq. units

Step-by-step explanation:

in order to find the area of a triangle you have to use the formula

1/2 b h

b as in base

h as in height

so if we use the measurements on the triangle and we plug that in we will get

1/2 x 14 (the base) x 5 (the height)

therefore giving us 35 sq. units.

Answer: 1/14, 2/28.

Step-by-step explanation:

2/7 x 0.25 =

Convert 0.25 into a fraction.

0.25 = 1/4.

Multiply the numerators together and then multiply the denominators with each other.

1/4 x 2/7 = 2/28.

Therefore, the answer is 2/28, but it can also be simplified to 1/14. So the answer is the first one, or 1/14.

Answer:

1/14 or A

Step-by-step explanation:

0.25 as a fraction is 1/4

1/4 x 2/7 = 2/28, simplify to become 1/14, and there is your answer

Answers

Answer:

x = - 8/23

y = 40/23

Step-by-step explanation:

-5x- y = 0

and

-8x+3y = 8

The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.

-5x-y = 0

-y = 5x

y = - 5x

Now you can take this y value and plug it into the section equation.

-8x + 3(-5x) = 8

-8x - 15x = 8

-23x = 8

x = - (8/23)

Once you get the x value you can plug it back into equation one to get y's value

-5*-(8/23)  - y = 0

40/23 - y = 0

y = 40/23

Step-by-step explanation:

[tex] \tt{30.16 = 17.56 + 5x} [/tex]

Swap the sides of the equation :

⤑ [tex] \tt{17.56 + 5x = 30.16}[/tex]

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ [tex] \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}[/tex]

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ [tex] \tt{5x = 12.6}[/tex]

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ [tex] \tt{ \frac{5x}{5} = \frac{12.6}{5}} [/tex]

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

[tex] \pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}[/tex]

the grocery store sells 4 pints of strawberries for 13.80 how much does it cost per pint

Answers

Answer:

3.45

Step-by-step explanation:

if 4 pints are 13.80 you would have to divided 13.80 by 4 and 4 by 4 to get 1 over blank. The denominator would be 3.45 which would be the amount 1 pint cost. If you don't want to do it as fractions you can simply divide 13.80 by 4.

3.45 the reason is because all you have to do is divide 4 by 13.80 and that gives you the original cost.

From 1970 to 1980, the number of pounds of glass per person per day decreased by 0.002 per year.
c.
From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.
b.
From 1970 to 1980, the number of pounds of glass per person per day decreased by 0.11 per year.
d.
From 1970 to 1980, the number of pounds of glass per person per day increased by 0.11 per year.

Answers

The correct option regarding the average rate of change for glass is given by:

c. From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.

What is the average rate of change of a function?

It is given by the change in the output divided by the change in the input.

Looking at the table, in the 10 years from 1970 to 1980, the amount of glass changed from 0.34 pounds to 0.36 pounds, hence the rate is given by:

r = (0.36 - 0.34)/10 = 0.02/10 = 0.002.

Which means that option c is correct.

Models are smaller than the real thing.

So if a house is 22 meters long, a model (like a Lego version) would be how long? The scale they give says 1cm (model length) = 4 meters (real length).

How many measures of 4 meters are in 22?

22/4 = 5 1/2, so the model would be 5.5 or 5 1/2 cm long.
