im having trouble with this one

Answer:

Step-by-step explanation:

A sales tax is never applied until money actually changes hands.

So you need to start by taking 50% off.

50% 0f 80 dollars = 50/100 * 80 = 4000/100 = 40

So the cost of the painting = 80 - 40 = 40

Now apply the sales tax

10% of 40 dollars = 10/100 * 40 = 400/100 = 4

The total cost = 40 + 4 = 44 dollars

Answer:

1 1/2

Step-by-step explanation:

To solve this problem, we need to find how many miles Terry walks in one day. Then, we can multiply by 3 to find how far she walks in three days.

One day |

We need to add how much she walks in both the morning and afternoon. 1/4 + 2/4 = 3/4 miles.

Three days |

Now that we know how much Terry walks in one day, we need to find how much she walks in three days. Multiple by 3 to solve this.

3/4 * 3 = 6/4 = 3/2

You can write 3/2 as an improper fraction: 1 1/2.

I hope this was helpful! Have a good day!

Step-by-step explanation:

as the first 2 lines show us : there is a linear relationship between minutes and words.

1 minute correlates to 250 words.

2 minutes correlate to 500 = 2×250 words.

so, we see, every minute represents 250 words.

therefore, 3 minutes (A) correlate to 3×250 = 750 words.

and 5 minutes (B) correlate to 5×250 = 1250 words.

The value of x for the given circle will be going to be 50°.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In another meaning, a circle is a geometrical figure whose shape is just like round wheel.

In our daily life, we always see circle objects for example our bike wheel.

Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

Angles of Intersecting Chords Theorem;

When two chords cross inside of a circle, the resulting angle's measure is equal to the product of the lengths of the arcs it intercepts and its vertical angle, divided by two.

So angle x = (60° + 40°)/2  = 50° hence it will be correct answer.

Step-by-step explanation: the distance is the time spent times 60 miles per hour.

The product of expressions is gotten by multiplying the expressions

The expression that give the same product as 5 * 3/7 is 3 * 5/7

The product expression is given as:

5 * 3/7

Evaluate the product

5 * 3/7 = 15/7

Express 15 as the product of 3 and 5.

So, we have:

5 * 3/7 = 3 * 5/7

Hence, the expression that give the same product as 5 * 3/7 is 3 * 5/7

Answer:

238 square feet

Step-by-step explanation:

Answer:

245 square feet.

Step-by-step explanation:

7 times 7 is 49

49 times 5 because there is 5 feet

= 245

1 hour = 60 minutes

45 min = (45 min)/(60 min) = 45/60 = 3/4 of an hour.

To go from 45/60 to 3/4, I divided both top and bottom by the GCF 15.

Answer:

45 minutes equal to 3/4 of an hour because, if you convert the one hour into minutes (60 minutes) it is divisible by 15 four times.

3 · 15 = 45.
