Answer 1

Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

-7 -7

2x = 8

divide by 2 to isolate x

x = 4

2nd pic) y - 3 <= 6

y - 3 <= 6

+3 +3

y <= 9

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

-0.5 -0.5

x = x + 5.5

NO SOLUTION

4th pic) 5m + 10 <= 130

5m + 10 <= 130

-10 -10

5m <= 120

divide by 5 to isolate the m

m <= 24

5th pic) 2c - 8 > 0

2c - 8 > 0

+8 +8

2c > 8

divide by 2 to isolate the c

c > 4

Tanya is training a turtle for a turtle race. For every 1/2 of an hour that the turtle is crawling, he can travel 2/23 of a mile. At what rate is the turtle crawling in miles per hour?

Answers

Answer:

To determine at what unit rate the turtle is crawling, divide 3/20 mile by 1/6 hour.

Therefore, the unit rate is 9/10 of a mile per hour

Step-by-step explanation:

The rate of turtle crawling is 4/23 miles per hour.

Given that, the time taken by turtle to crawl = 1/2 hour and number miles crawled by turtle = 2/23 mile

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Now, Speed = Distance/Time

= 2/23 ÷ 1/2

= 2/23 × 2/1

= 4/23 miles per hour

Hence, the rate of turtle crawling is 4/23 miles per hour.

If a radius of a sphere is divided by 2, will the surface area be divided by 2?

Answers

If r is the radius of a sphere its surface area = 4(pi)r^2.

If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.

So the surface area becomes 4-fold or the increase in surface area is 300%.

Answer:

Step-by-step explanation:

So our equation is:

First remove parenthesis:

7x+5+5x+3+12x-20=276

Combine like terms:

Add 12 on both sides:

24x = 288

Dakota earned $15.75 in interest in Account A and $28.00 in Account B after 21 months. If the simple interest rate is 3.0 for Account A 4.0% for Account B, which account had the greater principal? Explain

Answers

Answer: account B had the greater capital.
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount deposited.
P represents the principal or amount deposited
R represents interest rate
T represents the duration in years.
Considering account A,
I = $15.75
T = 21 months = 21/12 = 1.75 years
R = 3%
Therefore,
15.75 = (P × 3 × 1.75)/100
15.75 = 0.0525P
P = 15.75/0.0525
P = 300
Considering account B,
I = $28
T = 21 months = 21/12 = 1.75 years
R = 4%
Therefore,
28 = (P × 4 × 1.75)/100
28 = 0.07P
P = 28/0.07
P = $400
Therefore, account B had the greater capital.

account b had greater

Explanation:

Mae Ling earns a weekly salary of $310 plus a 7.5% commission on sales at a gift shop. How much would she make in a work week if she sold $4,700 worth of merchandise?

someone please answer ASAP i'll give brainlist to the best answer <3

Answers

Answer: 662.50 dollars

==========================================================

Explanation:

If she doesn't sell a single thing, she still earns the base weekly salary of $310. This is the smallest amount she can earn per week.

If she does make sales, then she'll earn an additional 0.075x dollars where x is the amount of sales made (the total value of the merchandise). The 0.075 is the decimal form of 7.5%

In total, she makes 0.075x+310 dollars per week. In this case, she sold x = 4700 dollars worth of goods, which means,

0.075x+310 = 0.075*4700+310 = 662.50

She earned 662.50 dollars for that week.

It’s $345.25 bc you have to multiply commission and the money sold which is .075 x 4,700 which equals 34.25 and then you add the weekly salary which is 310 and you get $345.25

A restaurant serves a 24-fluid ounce glass of soda that is 40% ice. How many fluid ounces of soda are served
Need help its a test!!!!

Answers

Answer:

14.4 fl ounces

Step-by-step explanation:

60% of 24 is 14.4

The percentage is calculated by dividing the required value by the total value and multiply it by 100.

100% = 24 fluid ounce

60% = 14.4 fluid ounce

The amount of soda in the glass of soda is 14.4 fluid ounces.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiply it by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

A glass of soda = 24 fluid ounce

A glass of soda = Soda + Ice

The percentage amount of ice in the glass of soda = 40%

The percentage amount of soda in the glass of soda.

= 100% - 40%

= 60%

A glass of soda = 24 fluid ounce

This can be written as,

100% = 24 fluid ounce

Multiply 60/100 on both sides.

60/100 x 100% = 60/100 x 24 fluid ounce

60% = 14.4 fluid ounce

Thus,

The amount of soda in the glass of soda is 14.4 fluid ounces.
