PLEASE HELP!! ALL STARS!! <33

Answers

Answer:

58.69 gallons is the maximum she can get.

Step-by-step explanation:

165 + 2.3g ≤ 300

subtract 165 from both sides

2.3g ≤ 135

divide by 2.3 on both sides

g ≤ 58.6956521739

During a film festival, the first film ticket is priced at $16, and each additional ticket is $11. If Rico spends $71, then how many tickets did he purchase?

Answers

Answer:

Step-by-step explanation:

16 + 11x = 71

16 + -16 + 11x = 71 + -16

16 + -16 = 0

0 + 11x = 71 + -16

11x = 71 + -16

11x = 55

x = 5

Cathy is playing a game with a set of 24 cards equally divided into 4 colors (red, green, blue, and yellow). Find the probability of her randomly selecting a red card, not replacing it, and then selecting another red card.

Answers

Answer: 0.054

Step-by-step explanation:

Cathy is playing a game with a set of 24 cards equally divided into 4 colors. This means that each card has 24/4 = 6 colors.

The probability of selecting the first red card will be 6/24. The probability of selecting the second one will be 5/23 without replacement.

Therefore, probability of her randomly selecting a red card, not replacing it, and then selecting another red card will be:

= 6/24 × 5/23

= 30/552

= 0.054

Jessica school bus stop is 60 yards from her house.For a normal school week, how many feet will Jessica walk to and from the bus stop?

A 300 feet

B 600 feet

C 900 feet

D 1,800 feet

winner gets 100 points

Answers

Answer:

Step-by-step explanation:

school is only 5 days a week and if she walks 60 yards to the bus stop and 60 yards back from the bus stop than she walks a total of 120 yards a day

120 x 5 =600 the answers are in feet so we need to convert to feet and to do that we need to multiply by 3

600x3=1800

so she walks 1800 feet in a normal school week

C. K'(0, 2), L'(2, 27), M'(12, 2)
D. K'(0, 6), L'(6, 27), M'(12, 6)

Answers

Answer: Choice D

K'(0, 6), L'(6, 27), M'(12, 6)

=============================================

Explanation:

Point K is located at (0,2)

If we multiply each coordinate by 3, then K moves to a location that is 3 times further away in relation to the origin. It moves to K'(0,6)

We apply this same scale factor (3) to each coordinate of the other 2 points

L(2,9) moves to L'(6,27) after multiplying both parts by 3

M(4,2) moves to M'(12,6) after multiplying both parts by 3

Triangle KLM is similar to triangle K'L'M', but the two triangles are not congruent (since K'L'M' is larger in size).

Write 60/8 as a mixed number. Give your answer in its simplest form.

Answers

Answer:

60 above the division line is called the numerator and 8 below the divison line is called the denominator.

We call the line that separates 60 and 8 the division line. It is also known as the fraction bar or vinculum.

60/8 is an improper fraction because the numerator is greater than the denominator.

A mixed number is an integer (whole number) and a proper fraction.

Step-by-step explanation:

Answer: 7/ 1/2

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

60/8= 7.5 = 7

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (7) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:

60 - (8 x 7) = 4

Step 3: Our mixed fraction

We've now simplified 60/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

Step 4: Simplifying our fraction

In this case, our fraction (4/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 4 and 8 is 4.

We can now divide both the new numerator and the denominator by 4 to simplify this fraction down to its lowest terms.

4/4 = 1

8/4 = 2

When we put that together, we can see that our complete answer is:

Write the equation of the line that passes through point (-10, -5) and is parallel to the line represented by the equation y = -2x + 7 in slope-intercept form.

Answers

Answer:

y = 2x + 15

Step-by-step explanation:

y = 2x + 7 (-10,-5)

find your b/ y-intercept

y = mx+b 2= slope

plug in your (x,y) points

-5 = 2(-10) + b

-5 = -20 + b

15 = b

y=2x + 15
