An 8-ounce cup of gourmet coffee costs $4.50. If the unit price remains the same, how much would 3 quarts of coffee cost?

Answers

Answer 1

Answer: Since there are 32 fluid ounces in 1 quart and we need 3 quarts we multiply 32 and 3 and get the result of which is 96 we need to divide that by eight to get the correct number to multiply 4.50 by so we get the result of 12 now it is 12 times 4.50 which is 54 so it costs 54 dollars. I hope this was helpful.

Answer 2

Answer: 1 quart = 32 fl oz.
This means that if there are 3 quarts, and each quart contains 32 ounces, 3 quarts have 96 ounces.
3 quarts * 32 oz = 96 oz

Now, set up a proportion.
8 oz is to $4.50 as 96 oz is to "x"

8 oz = $4.50
96 oz = x

Cross multiply to solve.

4.50 * 96 = 8x
432 = 8x
Divide both sides by 8:
x = 54

3 quarts of coffee would cost $54.
This doesn't make sense in a real life situation, but I'm confident that it is correct.

Choose the kind or kinds of symmetry the following figure

Answers

Answer:

i) Line

ii) point

Step-by-step explanation:

Given is a number 3. We have to find the kind or kinds of symmetry

On seeing 3, we find that no vertical line can divide 3 into exactly two symmetrical figures.

But if we draw a horizontal line in the middle of 3, we get two symmetrical figures up and down the line.

Hence i) symmetric about a line

Next is imaging the middle of 3 end point.

At that point we find that the figure is symmetrical on all sides of the point

Hence there is also a point symmetry

Kinds of symmetry are

i) Line

ii) point

Which represents a quadratic function? f(x) = 2x3 + 2x2 – 4 f(x) = –7x2 – x + 2 f(x) = –3x + 2 f(x) = 0x2 + 3x – 3

Answers

Answer:

Second option: $f(x) =-7x^2 -x + 2$

Step-by-step explanation:

A quadratic function has the form:

$f(x)=ax^2+bx+c$

(Where $a\neq0$ )

You can observe that the highest exponent of a quadratic function is 2.

Then, let's check which of the options shows a quadratic function:

1) $f(x) = 2x^3 + 2x^2 - 4$

Its highest exponent is 3, then this is not a quadratic function.

2) $f(x) =-7x^2 -x + 2$

Its highest exponent is 2 and $a\neq0$ , then this is a quadratic function.

3) $f(x) = -3x + 2$

Its highest exponent is 1, then this is not a quadratic function.

4) $f(x) =0x^2+3x-3$

You can observe that $a=0$ , then this is not a quadratic function.

Answer:

B. f(x) = –7x2 – x + 2

Mrs.Williams is knitting a blanket for her new bork granddaughter.The blanket is 2.25 meters long and 1.8 meters wide. what is the area of the blanket? Write the answer in centimeters.

Answers

The blanket is 2.25 meters long and 1.8 meters wide

Blanket will be in the shape of rectangle

Area of rectangle formula is Length * width

Given : Length = 2.25 meters

width = 1.8 meter

Area = Length * width

= 2.25 * 1.8 = 4.05

so the area of the blanket = 4.05 square meters

We need to convert the answer in centimeters

1 meter = 100 cm

4.05 meters = 4.05 * 100 = 405 square cm

the area of the blanket = 405 square cm

The blanket's area is 40,500 cm²

Further Explanation

The blanket length is 2.25 m

width is 1.8 m

The blanket usually in rectangular shape, so to calculate the area of the blanket would be:

$\boxed {AREA = length * width }\n \boxed {=2.25 *1.8 }\n \boxed {=4.05 }$

so the blanket's area is 4.05 m²

Here is how to do decimal numbers multiplication:

2.25 ⇒ 2 decimal place

1.8 x ⇒ 1 decimal place

1800

235 +

4.050 ⇒ 3 decimal place

to multiply decimal numbers, it is the same process as multiply the whole numbers, except the decimal place position. In the calculation above:

the first factor has 2 decimal place

the second factor has 1 decimal place

so the result will have 3 decimal place (2+1)

Back to the question, after we find out the blanket's area in meters, let's convert it to centimeters

$\boxed {1 m = 100 cm }\n \boxed {(1m)^(2) = (100cm) ^(2) }\n \boxed {1m^(2) = 10000 cm^(2) }$

so $\boxed {4.05m^(2) = 4.05 * 10000 cm^(2) }\n \boxed {=40500cm^(2) }$

The blanket's area is 40,500 cm²

What percent of 60 is 15

Answers

25%.

15 = 25%
30 = 50%
45 = 75%
60 = 100%

15/60 = 1/4 or 25 %

or
n% x 60 = 15 (the statement you wrote above changed into math)

.60n = 15 What allows me to move the decimal back two places? Normally you can change a percent to a decimal by moving it back two places. But if you don't know what the % is, you can move the number you are multiplying by back two places instead.
For example: 37 x .45 = .37 x 45 both = 16.65 - this shows that it doesn't matter which number is moved back two places - the answer will be the same. You can't move n% back two places (because you can't move a number you don't know back two places) so just move the number you are multiplying by, namely 60, back two place - that is how I got .60

.60n=15
.60 .60 divide both sides by .60

n= 25%
