To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.

Answers

Answer 1
1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.
Answer 2

Step-by-step explanation:

To obtain score of 80% on entire exam means the student have to answer

(80/100)×80 = 64 correct answers

Student have already answered 75% of the first 60 questions correctly meaning

(75/100)×60=45 correct answers from first 60 questions

Remaining correct answers s/he have to answer

64-45=19

So from remaining 20 questions s/he have to answer 19 correct questions that is

20 × (x/100) = 19

x = 19 ×(100/20)

x = 95%

Carina is borrowing $27,000 to buy a new car. If she borrows the money at 4.15% interest compounded annually for 5 years, how much interest will she pay on her car loan?
$33,087.21
$6,087.21
$1,120.50
$5,602.50

Answers

She will have to pay $6,087.21 in interest

Answer:

NO, the these three border pieces will not make a right triangle

Step-by-step explanation:

Use the compound amount formula A = P(1 + r)^t:

Here A = ($27,000)(1 + 0.0415)^5

         A = ($27,000)(1.0415)^5 = $33,087.21

Subtracting the principal amount, $27,000, leaves the compound interest amount:  $33,087.21 - $27,000 = $6087.21

She will pay $6,087.21 interest on this loan.

The volume of the cereal box is [tex]\rm 228\dfrac{3}{4}[/tex]cubic inches.

What is the volume of rectangular prism?

The volume of rectangular prism is given by :-

[tex]\rm Volume = Length \times Width \times Height[/tex]

Demarcus has a cereal box shaped like a rectangular prism. It measures 7 5/8 inches long, 2 1/2 inches wide, and 12 inches high.

The volume of the cereal box is determined in the following steps given below.

[tex]\rm Volume = Length \times Width \times Height\\\\\rm Volume = 7\dfrac{5}{8}\times 2\dfrac{1}{2} \times 12\\\\\rm Volume = \dfrac{7\times 8+5}{8} \times \dfrac{2\times 2+1}{2} \times 12\\\\\rm Volume = \dfrac{61}{8} \times \dfrac{5}{2} \times 12\\\\Volume =\dfrac{3660}{16}\\\\Volume=228\dfrac{3}{4}[/tex]

**WILL GIVE BRAINLIEST IF 4 OR MORE ARE CORRECT**

Answers

Answer:

-(x-120)

x-(-12)

-(x-(-12))

0

x / 3

-(x/3)

0

Step-by-step explanation:

1. || x-120||, if x<-120.

If x is less than -120, then x - 120 will be a negative number.

Since absolute value will make a negative number positive, the answer will be  -(x-120).

2. ||x-(-12)||, if x > -12.

Basically x -(-12) = x + 12. If x is greater than -12, then ||x+12|| will be positive. The answer is x-(-12).

3. ||x-(-12)||, if x < -12.

Again, x-(-12) = x + 12. If x is less than -12, ||x+12|| will be negative.

Absolute value makes a negative number positive. The answer is -(x-(-12)).

4. ||x-(-12)||, if x = -12.

So we can substitute x with -12. ||-12-(-12)|| = ||-12+12||, which equals ||0||, which is also just 0. (Answer is 0.)

5. ||x / 3||, if x > 0.

Any positive number divided by another positive number will be positive, meaning you can just take out the absolute value sign. Answer is x /3.

6. ||x / 3||, if x < 0.

Any number less than 0 is negative, and any negative number divided by a positive number will be negative. If we take out the absolute value, we'll have to reverse it with a -. Answer: -(x/3).

7. ||x / 3||, if x = 0.

||0/3|| = ||0||, which is still 0.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118

A cylindrical shaped swimming pool has a diameter of 30 feet and a water height of 4.5 feet. How many cubic feet of water is contained in the pool? Use 3.14 for pi. Round your answer to the nearest cubic foot.

Answers

Answer:  A

Step-by-step explanation:

The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.

Next, the volume of a cylinder is V= πr²h

R is the radius

h is the height

π= 3.14 (in this question).

We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.

R= 15

H= 4.5

Pi= 3.14

Now we can plug into the formula:

Using pemdas, do exponents first. Then multiply from left to right.

V= πr²h

V= 3.14x15²x4.5

V= 3.14x225x4.5

V= 706.5x4.5

V= 3,179.25

3,179.25  rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A

How do you convert mass to volume without density?

Answers

Answer:

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
