HElp K 12 test! Will give brainiest PLS HELP!!!!

Salsk061 [2.6K]

Answer:

1. d 2. a 3. d 4. a 5. a

Step-by-step explanation:

For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.

2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.

3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.

4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.

5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

Rauol measured the height of 12 different plants in his garden in April. He measured them again in June. What is the difference

jasenka [17]

The question is incomplete. Here is the complete question.

Raoul measured the ehight of 12 different plants in his garden in April. He measured them again in June.

April Heights (in inches) 12 15 23 11 42 45 44 39 12 19 20 12

June Heights (in inches) 45 45 40 43 11 14 12 13 41 40 45 41

What is the difference between the mean height in April and the mean height in June?

Answer: The difference between means is 8.0

Step-by-step explanation: Mean is the average of a set of numbers.

It is calculated as:

$\mu=\frac{\Sigma x}{n}$

where

x is the numbers in the set

n is how many numbers are there in the set

For heights in April, the mean is:

$\mu_{1}=\frac{12+15+23+11+42+45+44+39+12+19+20+12}{12}$

μ₁ = 24.5

For heights in June, the mean os:

$\mu_{2}=\frac{45+45+40+43+11+14+12+13+41+40+45+41}{12}$

μ₂ = 32.5

The difference between means:

μ₂ - μ₁ = 32.5 - 24.5 = 8.0

The difference between the mean height in April and in June is 8.0 inches.

At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two

Svetlanka [38]

Answer: 290 calories in a cheeseburger and 230 calories in fries.

x = calories in a cheeseburger

y = calories in an order of small fries

Four cheeseburgers and five small fries have 2,310 calories. Therefore

4x + 5y = 2310 (1)

Three cheeseburgers and two small fries have 1,330 calories. Therefore

3x + 2y = 1330 (2)

Equations (1) and (2) model the given situation.

To solve, multiply (1) by 2, and multiply (2) by 5 to obtain

 8x + 10y = 4620 (3)

15x + 10y = 6650 (4)

Subtract (3) from (4).

7x = 2030

x = 290

From (1), obtain

5y = 2310 - 4*290 = 1150

y = 230

 x = 290, y = 23

Hope this helps!
