What temperature is 10 degrees higher than minus 7 degrees

Answers

Answer 1

Answer: This could be done in two ways:
Using a sum
It would be:
-7 + 10
which equals 3

Using a numberline
See the attached numberline. Find -7, and count 10 along to the right to find the answer (3)

Answer 2

Answer: $-7^o+10^o=\boxed{3^o}$

62% of 150 is what number

Answers

First put the percent into decimal form. This is .62.
Then multiply .62 by 150. This is 93. 93 is 62% of 150.

Put 62/100 = x/150. If you simplify you should be able to get your answer.

Steve has a steel barrel with a diameter of 4 feet that can be filled to a depth of 4.3 feet with oil. What is the volume of the barrel?Use = 3.14

A.
54.008 cubic feet

B.
51.6 cubic feet

C.
78.128 cubic feet

D.
17.708 cubic feet

Answers

Answer:

Option A. 54.008 cubic feet

Step-by-step explanation:

we know that

The volume of the barrel is equal to

$V=\pi r^(2)h$ ----> volume of the cylinder

we have

$r=4/2=2\ ft$ ----> the radius is half the diameter

$h=4.3\ ft$ ---> is the depth

$\pi =3.14$

substitute

$V=(3.14)(2)^(2)(4.3)$

$V=54.008\ ft^(3)$

Answer:Concept Development: We have learned why scientific notation is indispensable in science. This means that we have to

learn how to compute and compare numbers in scientific notation. We have already done some computations, so we

are ready to take a closer look at comparing the size of different numbers.

Step-by-step explanation:There is a general principle that underlies the comparison of two numbers in scientific notation: Reduce everything

to whole numbers if possible. To this end, we recall two basic facts.

1. Inequality (A): Let and be numbers and let > . Then < if and only if < .

2. Comparison of whole numbers:

a. If two whole numbers have different numbers of digits, then the one with more digits is greater.

b. Suppose two whole numbers and have the same number of digits and, moreover, they agree digitby-digit (starting from the left) until the

th place. If the digit of in the ( + )

th place is greater than

the corresponding digit in , then > .

The opposite of the original statement. These statements are also called the inverse of a conditional statement.

Answer:

Negation is the correct answer to the given question

Step-by-step explanation:

The main objective of Negation is to evaluated the inverse of a specified computational statement or the conditional statement. If the conditional statement is true then the negating statement is false or if the conditional statement is false then the negating statement is True .The negation is represented by the symbol ~ .

For example :

F: Number is 5.

~F: Number is not 5.

Conditional statement Negation(~)

True False

False True

All the other option are not determine the inverse of the conditional statement so these are incorrect option .

Nagaraj has a party-length sandwich that is 55 inches long and is to be cut into three pieces. The middle piece will be 4 inches longer than the shortest piece, and the shortest piece will be 9 inches shorter than the longest piece. How long will the pieces be?

Answers

Answer:

S = 14 inches

M = 18 inches

L = 23 inches

Step-by-step explanation:

Let's being by defining our variables:

Shortest piece = S

Middle piece = M

Longest piece = L

So now we need to write down what formulas we're given:

"Nagaraj has a party-length sandwich that is 55 inches long and is to be cut into three pieces"

so we can start by knowing the S + M + L = 55

"The middle piece will be 4 inches longer than the shortest piece"

This means that M - 4 = S

"the shortest piece will be 9 inches shorter than the longest piece"

Finally, this means that S + 9 = L

What we need to do now is turn all of these things into the form of one letter. We can see that S is in all three of these equations, so lets solve everything in terms of S.

M = S + 4

L = S + 9

Now we can plug in both of those things into our first equation to get:

S + S + 4 + S + 9 = 55

and now we solve :)

3S = 42

S = 14

So now given this we can use this to solve the other three lengths

M = 14 + 4 = 18

L = 14 + 9 = 23
