(-5)+(+7)=( ___

Please help. I don't understand how to do these problems.

Answer:

11a. m <1 = 131 12a. m <1 = 42

11b. m <2 = 49 12b. m <3 = 75

11c. m <3 = 131 12c. m <4 = 42

11d. m <4 = 49 12d. m <5 = 63

11e. m <5 = 131 12e. m <6 = 75

11f. m <6 = 49 12f. m <7 = 105

11g. m <8 = 49 12g. m <8 = 75

11h. m <9 = 92 12h. m <10 = 75

11i. m <10 = 88 12i. m <11 = 42

11j. m <11 = 92 12j. m <12 = 138

11k. m <12 = 88 12k. m <13 = 42

11l. m <13 = 92 12l. m <14 = 138

11m. m <14 = 88

11n. m <15 = 92

Step-by-step explanation:

When lines are parallel to each other than:

Corresponding Angles are equal.

Alternate Interior Angles are equal.

Alternate Exterior Angles are equal.

Consecutive Interior Angles add up to 180 degrees.

You can check some math websites for definitions of these angle relationships.

A storage closet holds twelve boxes stacked upon each other, with each box being 10 inches high. How many feet are there between

Vikentia [17]

Answer:5

Step-by-step explanation:there are 6 boxes between the top of the 3rd box and the bottom of the 10th box.

Since each box is 10 inches tall, the length of the 6 boxes sum up to 60 inches.

and since 12 inches =1 feet,

Then 60 inches = 5 feet

How to solve

Let "y" = the unknown number of feet's

12 inches = 1 feet

60 inches = y

Cross multiply

> 12×y =60×1

> 12y =60

Divide both sides by 12 since you want the value of "y".

> 12y÷12=60÷12

So 12 cancels out leaving the final answer to be:

> y=5

Will mark brainli if you give explanation

dmitriy555 [2]

Answer:

960 ft²

Since you are doing volume, your multiplication sentence would look like

Length * Width * Height

Now, if you multiply 10 * 8 * 12, your answer will be 960 ft²

What is the radical form of each of the given expressions? 4 1/7 AND 4 7/2 AND 7 1/4 AND 7 1/2 I WILL UPVOTE

PilotLPTM [1.2K]

Assuming these are 4^(1/7), 4^(7/2), 7^(1/4) and 7^(1/2), the conversion process is pretty quick. the denominator, or bottom, of your fraction exponent becomes the "index" of your radical -- in ∛, "3" is your index, just for reference. the numerator, aka the top of the fraction exponent, becomes a power inside the radical.

4^(1/7) would become ⁷√4 .... the bottom of the fraction becomes the small number included in the radical and the 4 goes beneath the radical
in cases such as this one, where 1 is on top of the fraction radical, that number does technically go with the 4 beneath the radical--however, 4¹ = 4 itself, so there is no need to write the implied exponent.

4^(7/2) would become √(4⁷) ... the 7th power goes with the number under your radical and the "2" becomes a square root

7^(1/4) would become ⁴√7 ... like the first answer, the bottom of the fraction exponent becomes the index of the radical and 7 goes beneath the radical. again, the 1 exponent goes with the 7 beneath the radical, but 7¹ = 7

7^(1/2) would become, simply, √7
