Answer:
The answer is 6x² - 21x.
Step-by-step explanation:
You have to substitute the expressions inro the formula :
[tex]A = length \times width[/tex]
[tex]let \: l = 2x - 7,w = 3x[/tex]
[tex]A = (2x - 7) \times 3x[/tex]
[tex]A = 3x(2x - 7)[/tex]
[tex]A = 6 {x}^{2} - 21x[/tex]
The area of the rectangular garden is 6x² - 21x.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know, The area of a rectangle is (length×width).
Given, The rectangular garden has a length of (2x - 7) and a width of 3x.
Therefore, The area of the garden is,
= (2x - 7)×3x.
= 6x² - 21x.
= x(6x - 21).

Gary had 30 dollars to spend on 3 gifts. He spent 9 1 4 dollars on gift A and 6 4 5 dollars on gift B. How much money did he have left for gift C?
Answer:
$13.95
Step-by-step explanation:
Total Amount to spend on gifts = $30
Number of gifts to purchase = 3
Amount spent on gift A = $9 1/4
Amount spent on gift B = $6 4/5
Amount left to spend on gift C:
Total amount - (gift A + gift B)
$30 - ($9 1/4 + 6 4/5)
$30 - (37/4 + 34/5)
$30 - (185 - 136) / 20
$30 - 321 / 20
30 - 16.05
$13.95

Answer:
-42
Step-by-step explanation:
Since she is handing them equally to her four nieces, then she has to do 10.50 x 4
= 42 since they are asking how much checks were cashed, the answer will be negative so therefore the answer is $-42

One pipe can fill a tank in four hours; another pipe can fill the same tank in three hours. How long would it take to fill the tank if both pipes filled it at the same time? [?] hours Enter the number that belongs in the green box. Enter
9514 1404 393
Answer:
[tex]\dfrac{12}{7}[/tex]
Step-by-step explanation:
The first pipe fills 1/4 of the tank in 1 hour. The second pipe fills 1/3 of the tank in 1 hour. So, in 1 hour, the amount of the tank that is filled is ...
[tex]\dfrac{1}{4}+\dfrac{1}{3}=\dfrac{3}{12}+\dfrac{4}{12}=\dfrac{7}{12}\quad\text{of the tank in 1 hour}[/tex]
This number is the fill rate in tanks per hour. We want the reciprocal of that, the fill time in hours per tank. The reciprocal of 7/12 is 12/7.
It will take 12/7 hours to fill the tank.

It looks like you may be asked to fill two "green boxes" to provide the complete answer. The box shown as green in this question is the numerator of the fraction, so should be filled with 12. (We expect that the denominator entry will be made available as soon as you enter the numerator. Your experience with this web site will tell you if that is true.)
a candy shop contains a total of 300 items there are 125 chocolates 97 cookies and T number of truffles write an equation that represents the situation
Given:
A candy shop contains a total of 300 items.
There are 125 chocolates 97 cookies and T number of truffles.
To find:
The equation for the given situation.
Solution:
We have,
Number of chocolates = 125
Number of cookies = 97
Number of truffles = T
Total items = [tex]125+97+T[/tex]
A candy shop contains a total of 300 items. So,
[tex]125+97+T=300[/tex]
Therefore, the required equation for the given situation is [tex]125+97+T=300[/tex].
Maria and her friends ordered a pizza that cost $14.70. She paid $2.94 for her part. What percent of the total bill did she pay?
Answer:
14.70-2.94 = 11.76
11.76/14.70 = 0.8
0.8 X 100 = 80
100 - 80 = 20%

A roller coaster has 3 trains with 7 rows per train. Riders stand in rows of 6, for a total of 42 riders per train. The operators of the coaster recorded the number of riders on each train during a run. On the first train, the operators reported that 6 rows were filled. On the second train, all 7 rows were filled. On the third train, 4 rows were filled. How many rows were empty on the first train? How many additional riders would it take to fill those empty rows?
Answer:
a. 1 row
b. 6 people
Step-by-step explanation:
a. Each train has 7 rows yet the first train only had 6 rows filled up. This means that:
= 7 - 6
= 1 row was empty
b. Riders stand in rows of 6 which means that one row has 6 people. With only 1 row empty, the number of people needed will be:
= 6 people

Carrie is making a temporary ramp from the ground to the top of his patio so that he can roll a cart up to it to move furniture in. The surface of the patio is 3‘9“ above the ground and Gary wants the ramp to have a slope of no more than 0.375. What is the shortest horizontal distance he can have from the base of the patio to the base of the ramp
9514 1404 393
Answer:
10 ft
Step-by-step explanation:
The slope is rise/run. Using Gary's numbers, we have ...
m = rise/run
0.375 ≥ (3.75 ft)/run
run ≥ (3.75 ft)/0.375
run ≥ 10 ft
The shortest horizontal distance to the base of the ramp is 10 feet.

A rectangular picture frame has side lengths of 12 in by 9.5 in what is the length of the diagonal of the picture
Answer:
Length of diagonal of picture = 15.30 inches
Step-by-step explanation:
Given that:
Side lengths of picture frame = 12 inches by 9.5 inches
As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.
Using Pythagorean theorem;
a²+b²=c²
Putting the values in the theorem
[tex](12)^2 + (9.5)^2 = c^2 \\144+90.25=c^2\\c^2 = 234.25[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{234.25}\\c=15.30[/tex]
Hence,
Length of diagonal of picture = 15.30 inches
Factor the quadratic expression completely.

A small forest has 30 rabbits and grows continuously
at a rate of 60%. How many rabbits do you expect to
see in this forest after 5 years? Round your answer to
the nearest whole rabbit.
PLZZZZZZZZ HELP ASAP ND THANK YOU
========================================================
Work Shown:
P = 30 = initial populatione = 2.71828 = a constant (similar to pi = 3.14)r = 0.60 = growth rate in decimal formt = 5 = number of yearsApplying those values gets us the following
A = P*e^(r*t)
A = 30*2.71828^(0.60*5)
A = 602.56489
A = 603
After five years, there are approximately 603 rabbits in that forest.
