Answer:

The answer is A. $4.50 for 9 cans

Step-by-step explanation:

Divide 2.50 by 5 and you get $0.50 a can

Multiply $0.50 by each of your answers

A. 0.50 times 9 = 4.50

B. 0.50 times 1 = 0.50

C. 0.50 times 7 = 3.50

D. 0.50 times = 1.50

As you can see A. is the only one that matches

I hope this helps

Answer: from top to bottom: 115, 45, 115, 110, 115

Step-by-step explanation: 115 because the remain angle in that triangle is 65. 180-65 is 115. 45 because vertical angles are equal. 115 because 180-65 is 115. 110 because vertical angles are equal. 115 because vertical angles are equal.

Answer:

A. 2,100

Step-by-step explanation:

1 m = 100 cm

so, 21 m = 21×100

=2100cm.

Answer:

Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Round 4.275 to the hundredths, which equals 4.27

Answer: $4.28

Step-by-step explanation:

Answer:

y = 0.5x + 1

Step-by-step explanation:

Answer:

add

(a+10)+2a+44=180

Subtract 44 first so now our equation is

a+10+2a=136

3a+10=136

3a=126

a=42

plug it into 2a since this is our exterior angle

2(42)

=84 degrees

Answer: a

Step-by-step explanation:

Answer: Is the second

Step-by-step explanation:

I took the result of the tables of values ​​with the calculator and it gave me the result I regret not being able to give you an explanation

The exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]

An exponential function is represented as:

[tex]y = ab^x[/tex]

Where:

From the table we have the following ordered pair

(x,y) = {(0,18) (1,21.6)}

So, we have:

[tex]y = ab^x[/tex]

[tex]18 = a \times b^0[/tex]

[tex]a= 18[/tex]

Also, we have:

[tex]y = ab^x[/tex]

[tex]21.6 = a \times b^1[/tex]

[tex]21.6 = 18 \times b[/tex]

Divide both sides by 18

[tex]b = 1.2[/tex]

So, we have:

[tex]y =18 \times 1.2^x[/tex]

Rewrite as:

[tex]y =18 (\frac 65)^x[/tex]

Hence, the exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]

Answer:

A: 6c=75 If there were 6 movies then 6 times the cost of each movie would equal 75.

B:$12.50 We divide 75 by 6.

C: d+75=100 the cost left on the card plus 75 will equal 100.

D: $25 We subtract 75 from 100

Hope this helps :)

-ilovejiminssi♡

Answer:

6m = 75

Step-by-step explanation:

To find the cost per movie, we can divide. We can show this by using the equation 6m = 75.

6m/6 = 75/6

m = 12.5 per movie

Answer:

Brooke

Step-by-step explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner

Answer:

The answer would be B) 1,466.25

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or:

I= P x r x t

Where:

P is the principal amount, $1275.00.

r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1275 × 0.03 × 5 to get that:

The interest is: $191.25

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 1275.00 + 191.25 = 1466.25.
