Susan pays for the items and receives $0.80 in change. What amount of money does Susan use to pay for the items?

Answers

Answer: $30

Step-by-step explanation:

Your question isn't well written. Here's the complete question:

Susan buys the item listed below at a grocery store. 2 packages of chicken priced at $12.36 per package. 1/2 pound of broccoli priced at $1.98 per pound. 1gallon of milk priced at $3.49 per gallon. There is no sales tax on the food she buys. Susan pays for the items and recevies $0.80 in change. What amount of money does Susan use to pay for the items?

2 packages of chicken priced at $12.36 per package will cost:

= 2 × $12.36

= $24.72

1/2 pound of broccoli priced at $1.98 per pound will cost:

= 1/2 × $1.98

= $0.99

1 gallon of milk priced at per $3.49 per gallon will be:

= 1 × $3.49

= $3.49

We are then told that Susan pays for the items and receives $0.80 in change. The amount of money does Susan use to pay for the item will be:

= $24.72 + $0.99 + $3.49 + $0.80

= $30

y = x - 2
y = 3 x - 3

Answers

Answer:

[tex]y=2x-2[/tex] is the required equation.

Therefore, the second option is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation of a linear function is given by

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)[/tex]

[tex]m=\frac{0-\left(-2\right)}{1-0}[/tex]

[tex]m=2[/tex]

substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.

[tex]y=mx+b[/tex]

[tex]-2 = 2(0)+b[/tex]

[tex]-2=0+b[/tex]

[tex]b=-2[/tex]

Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function

[tex]y=mx+b[/tex]

[tex]y=2x+(-2)[/tex]

[tex]y=2x-2[/tex]

Thus, [tex]y=2x-2[/tex] is the required equation.

Therefore, the second option is true.

On Saturday, Kylee’s volleyball team will be having a family picnic. Hot dogs are sold at the local store with 15 hot dogs in a package. Hot dog buns, however, are only sold in packages of 6 hot dog buns. Kylee’s team wants to buy the exact same number of packages for hot dogs as hot dog buns.


What is the least number of packages of hot dogs and hot dog buns that Kylee’s team should buy to have exactly the same number of hot dogs as hot dog buns? If a package of hot dogs cost $2.98 and a package of hot dog buns cost $2.16, what was the total expense?

Answers

Answer:

Kylee's family need at least 2 packages of hot dogs and 5 packages of hot dog buns to have exactly the same number of hot dogs and hot dog buns.

Total expense is $16.76

Step-by-step explanation:

The lowest common multiple of 6 and 15 is 30.

Two packages of hot dogs contain 30 hotdogs.

Five packages of hot dog buns contain 30 hotdog buns.

If one package of hotdog costs $2.98, two packages would cost $2.98 × 2 = $5.96

If one package of hot dog buns costs $2.16, five packages would cost $2.16 × 5 = $10.8

$5.96 + $10.8 = $16.76

Find the surface area of the square pyramid

Answers

Answer:

The surface area of the square pyramid is 40 units².

Step-by-step explanation:

As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:

[tex]A=2bs+b^2[/tex]

From the figure, it is clear that

length of its base = 'b' = 4slant height = 's' = 3

substituting the values in the formula

[tex]A=2bs+b^2[/tex]

[tex]A=2\left(4\right)\left(3\right)+\left(4\right)^2[/tex]

    [tex]=2\left(4\right)\left(3\right)+16[/tex]

    [tex]=40[/tex]

Therefore, the surface area of the square pyramid is 40 units².

Answers

Answer: -53, 53

Step-by-step explanation:

It’s asking for the slope first, so let’s find it:

First, let’s determine our coordinates.

We have (1, 930) and (6, 655).

The slope equation is [tex]\frac{y_1 - y_2}{x_1 - x_2}[/tex], so let our (1, 930) be our x_1 and y_1, and (6, 655) be our x_2 and y_2.

So, we have,

= [tex]\frac{655-930}{6-1}[/tex]

This simplifies to

= [tex]\frac{-265}{5}[/tex]

which is -53.

Therefore, the slope is -53, so the balance decrease by $53 each month.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, An expression  18.1 - 1.1(7.4 - 9.6 + 0.5).

let us multiply each term of the expression to remove the decimal.

∴ 181 - 11(74 - 96 + 5).

= 181 - 11(-17).

= 181 + 187.

= 368 but the actual answer is 36.8 as we have to divide by 10.

Answer: x = 38

Step-by-step explanation:

1) Add 3x - 16 and x + 6 and x together. You get 5x - 10.

2) All sides of a triangle equals 180 degrees, so that means 5x - 10 = 180.

3) Add 10 to both sides, 5x = 190.

4) 190/5 = 38

Step 2: Solve for x

Subtract 4x on both sides:                    x - 7 > 8Add 7 on both sides:                             x > 15

Write an equivalent expression

-3 + 2/3y - 4 - 1/3y

Answers

Answer:

join the y-related together and the others together

ie -7+1/3y

thats the shortest form one can drill down to, so that should be the answer

Step-by-step explanation:

To write an equivalent expression, we need to simplify the given expression by combining like terms. Like terms are terms that have the same variable and exponent. We can use the distributive property to remove parentheses or other grouping signs to then combine like terms.

The given expression is -3 + 2/3y - 4 - 1/3y. We can see that there are no parentheses or grouping signs, so we can skip that step. We can also see that there are two like terms: 2/3y and -1/3y. We can combine them by adding their coefficients: 2/3 + (-1/3) = 1/3. So, we get:

-3 + 2/3y - 4 - 1/3y = -3 - 4 + (2/3 - 1/3)y = -7 + (1/3)y

This is the simplified expression that is equivalent to the given expression.
