Answers

Answer:

97

Step-by-step explanation:

Angle on a straight line = 180

106 + ∠st = 180

∠st = 180 - 106 = 74

x = ∠st + 23

= 74 + 23

= 97

Answer:

51 degrees

Step-by-step explanation:

This is a scalene triangle. Which means it sums up to 180 degrees. Therefore, you have to add up all the degrees to 180. 106+23 is 129, and 180 - 129 is 51.

Which size bottle of ketchup is the best deal with the lowest unit price?

Prices for Different Sizes of Bottles of Ketchup
Size Bottle
Price
10 oz.
$2.50
14 oz.
$2.80
16 oz.
$4.00
18 oz.
$5.40

Answers

Answer:

14oz for $2.80

Step-by-step explanation:

Well to determine the unit prices you must divide the price by whatever the weight is. As so:

10oz:  2.5/10=0.25

14oz:  2.8/14=0.20

16oz:  4/16=0.25

18oz:  5.4/18=0.30

So your answer is 14oz for $2.80

Answer: I’m pretty sure ur answer would be 14 oz. :)

Write the equation 7x - 4y = -12 in slope-intercept form

Answers

Hello,

The correct answer is: y = 7/4x + 3.

Step-by-step:

Move variables to the right side

-4y = -12 - 7x

Change the signs

4y + 12 + 7x

Divide both sides

y = 3 + 7/4x

Reorder the terms

y = 7/4x + 3

Answer: y = 7/4x + 3

Hope this helps!

I think it might be 6.75x - 19.25 = 80

Step-by-step explanation:

6.75x−19.25=80

Step 1: Add 19.25 to both sides.

6.75x−19.25+19.25=80+19.25

6.75x=99.25

Step 2: Divide both sides by 6.75.

6.75x/6.75 = 99.25/6.75

• If the point A(2,7) was dilated by a factor of 2 with a center at the origin and then translated
by three units left and four units down, its image would be located at which of the following?

A: (1,10)
B:(1,5)
C:(7, 18)
D:(10, 3)

Pleaseee help!!

Answers

Answer:

Answer option A:  (1, 10)

Step-by-step explanation:

With the dilation by a factor of "2" via the origin, the point A goes from:

(2, 7) --> (4, 14)

Then with a shift of three units left it goes:

(4, 14) --> (4 - 3, 14) = ( 1, 14)

Then when shifting it four units down, it goes:

(1, 14) --> (1, 14 - 4) = ( 1, 10)

Gas prices are expected to rise 5% each week for the next six weeks. Kevin spent $52.50 to fill his tank this week.
Which of the following represents the total amount Kevin can expect to spend to fill his tank over the next three
weeks, if he fills his tank once a week?
$52.50 + $55.13 + $57.76
$52.50 - $55.13 + $57.88
$55.13 + $57.76 - $60.39
$55.13 - $57.88 + $60.78

Answers

Answer:

D. $55.13 - $57.88 + $60.78

Step-by-step explanation:

52.50 x 1.05= 55.125 = 55.13

55.13 x 1.05= 57.88125 = 57.88

You can already eliminate a, b, and c because they don't match, so the answer is D.

The total amount is 55.13+57.88+60.78. Therefore, option D is the correct answer.

Given that, gas prices are expected to rise 5% each week for the next six weeks. Kevin spent $52.50 to fill his tank this week.

What is the percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100.

Now, in the first week 105% of 52.50

52.50 x 1.05= 55.125 = 55.13

In the second week 105% of 55.13

55.13 x 1.05= 57.88125 = 57.88

In the third week 105% of 57.88

57.88x 1.05= 60.775=60.78

So the total amount=55.13+57.88+60.78

Therefore, option D is the correct answer.

Answer:

6 movies = 1st plan

7 movies = 1st plan

8 movies = Either is fine. (They're the same price)

9 movies = 2nd plan

10 movies = 2nd plan

Step-by-step explanation:

6 movies (1st plan) = 20 + 5 × 6

                               = 50 (less than 60 so it is cheaper)

7 movies (1st plan) = 20 + 5 × 7

                               = 55 (less than 60 so it is cheaper)

8 movies (1st plan) = 20 + 5 × 8

                               = 60 (same as 2nd plan so either is fine)

9 movies (1st plan) = 20 + 5 × 9

                               = 65 (more than 60 so 2nd plan is better)

10 movies (1st plan) = 20 + 5 × 10

                               = 70 (more than 60 so 2nd plan is better)

To find the fraction just count the number of figures total. This is the denominator of your fraction

NExt just count how many spaces are shaded and that number is your numerator

For example in A we see that there is 4 triangles total

Therefore our fraction currently is x/4

NeXT we see that there are 2 shaded in

This makes our fraction 2/4 which if simplified is 1/2

Step-by-step explanation: To find the cost of the jacket after the discount just do 30 X .1 to get 3. Then take 3 and subtract it from 30. The mistake the clerk made was he probably just saw 10% and did 30-10=20. The clerk might have brain damage because this is like 5th grade math.

How to calculate the nth term of an arithmetic sequence?

The nth term of an arithmetic sequence is expressed according to the formula as shown:

Tn = a + (n -1)d

where:

a is the first term = 2

d is the common difference = 3.8 -2 = 1.8

Required

Fourth term (n = 4)

Substitute

T4 = 2 + (4 -1)(1.8)
T4 = 2+3(1.8)
T4 = 7.4

Hence the missing term of the arithmetic sequence is 7.4
