Answers

Answer:

1: 58

2: 140

Step-by-step explanation:

For blank 1:

arc SU is 180, this is because its the angle of the diameter.

arc TU is 122, because its the double of angle S, so 61 times 2 is 122.

- We know that a circle is 360 degrees, so 180 + 122 is 302

-Therefore 360-302=58.

For question 5:

Arc CA is 180, because it's the angle of the perimeter

Arc BC is 40, because its the double of angle A, so 20 times 2 is 40.

-  We know that a circle is 360 degrees, so 180 + 40 is 220.

- Therefore 360-220=140

Answers

Answer:

y=-3/4+9

Step-by-step explanation:

First off we know that they are parallel, so they have to have the same slope.

y=-3/4

that is all we have for now, so we have to find b, the y intercept

we know that Street F passes through the point (4,6), so we graph that.

now we look at the graph and we can see that it look like we can translate it up 7 units.

this will give us the equation

y=-3/4+9

Answers

Answer:

11 1/4 teaspoons

Step-by-step explanation:

So 3/4 + 1 1/2 teaspoons are in one pot, which means 5(3/4 + 1 1/2) teaspoons are in 5 pots.

5(3/4 + 1 1/2)

5(2 1/4)

10 5/4

11 1/4

Total pepper and salt combined are needed in order to make 5 pots of spaghetti sauce is, 45 / 4

We have to given that,

A chef added 3/4 teaspoon of pepper and 1 1/2 teaspoons of salt to each pot of spaghetti sauce.

Here, Total amount of pepper and salt for each pot of spaghetti sauce is,

3/4 + 1 1/2

3/4 + 3/2

Make denominator same by taking LCM of 4,2 which is 4.

3/4 + 6/4

(3 + 6) / 4

Therefore, Total pepper and salt combined are needed in order to make 5 pots of spaghetti sauce is,

5 x 9/4

3/12 x 6 with explanation!

Answers

Answer:

24 is the ans...................

Answer:

1 1/2

Step-by-step explanation:

3/12 * 6

6 is simply 6/1 so

3/12*6/1

multiply from side to side so

3*6=18

and

12*1=12

18/12

simplify to a mixed number

18 goes in 12 once with a remainder of 6, or 18-12=6 so

1 6/12

6/12 can both be simplified by 6 so you divide both by 6

6/6=1 and 12/6=2

1/2

add it back to the whole number

A local hamburger shop sold a combined total of 375 hamburgers and cheeseburgers on Friday. There were 75 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday? hurry please lol

Answers

Answer: 225 hamburgers were sold on friday

Step-by-step explanation:

Let x represent number of hamburgers

and x-75 represent cheeseburgers

such that total hamburgers and cheeseburgers sold on Friday equaling 375 can be represented as

x + (x-75) =375

2x-75=375

2x=375+75

2x =450

x=450/2=225

Hamburgers =225

cheeseburgers= x-75=225-75=150

F k = -2
G k = -3
H K = 3
J K = 7

Answers

Answer:

H. k = 3

Explanation:

3k - 5 = 0.8k + 3( 2 - k ) + 4.6

30k - 50 = 8k + 30( 2 - k ) + 46

30k - 50 = -22k + 106

Mr. Juarez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest. What is the total amount that Mr. Juarez will have in his account at the end of 3 years?

Answers

Answer:

$576.80

Step-by-step explanation:

We have been given that Mr. Juárez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest.

We are asked to find the total amount that Mr. Juárez will have in his account at the end of 3 years.

We will use simple interest formula to solve our given problem.

[tex]A=P (1+rt)[/tex]

A = Final amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Let us convert 1% into decimal form,

1%=1/100=0.01

P=$560 and t=3

A=$560 (1+0.01(3))

A=$560 (1+0.03)

A= $560 (1.03)

A= $576.80

Therefore, Mr. Juárez will have $576. 80 in his account at the end of 3 years. Hope this helps!
