Answer:
D) 35 sq ft
Step-by-step explanation:
The options are:
A) 24 sq ft B) 70 sq ft C) 12 sq ft D) 35 sq ft
So, when calculating the area of a regular rectangle or square, you need to multiply the base by the height (area=base*height)
So it is as simple as 7 multiplied by 5 which is 35 (7*5=35), so the answer is D) 35 square feet.

Víctor has 2 times as many trophies as Dean. Together ,víctor and Dean have 27 trophies does víctor have?
Answer:
Victor has 18 trophies
Step-by-step explanation:
Let's set up "let statements"
Let d = Dean's trophies
Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...
Let 2d = Victor's trophies
Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...
2d + d = 27
Combine like terms...(2d and d)
3d = 27
Divide 3 on both sides to isolate the variable "d"
3d ÷ 3 = d
27 ÷ 3 = 9
So...
d = 9
That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...
2 · 9 = 18
Therefore, Victor has 18 trophies!
Hope this helps :)
A side of a square is 10 cm longer than the side of an equilateral triangle. The perimeter of the square is 3 times the perimeter of the triangle. Select the equation that represents the scenario when x represents the side of the triangle.
Here's the solution :
Side of the equilateral triangle = x Side of square = x + 10perimeter of equilateral triangle = 3 × x = 3x
perimeter of square = 4 × (x + 10)
now, according to above statement :
permission (square) = 3 × perimeter (triangle)
that is :
[tex]4(x + 10) = 3 \times 3x[/tex][tex]4x + 40 = 9x[/tex][tex]9x - 4x = 40[/tex][tex]5x = 40[/tex][tex]x = 8[/tex]therefore, side of triangle = 8 cm
perimeter (triangle) = 8 × 3 = 24 cmside of square = 8 + 10 = 18 cmperimeter of square= 18 × 4 = 72 xmAnswer:
Let the side of the equilateral triangle = x
so the side of the square = x+10
The perimeter of the triangle = 3x
and the perimeter of the square = 4(x+10)
condition : the perimeter of the square is 3 times the perimeter of the triangle.
so, 4(x+10) = 3*(3x)

Eric is hiring a company to install carpeting in his house. The company charges a one-time installation fee plus a certain amount per square yard of carpeting. The graph below shows the relationship between the number of square yards of carpeting and the total cost, in dollars.
A. Slope of the graph
B. Y-intercept of the graph
C. Domain of the function
D. Range of the function
Answer:
As axjames said, it is A. Slope of the graph.
Step-by-step explanation:
A slope in a graph can mean a increase or a decrease in whatever. For example a decrease in miles per hour (mph), business sales, and more. Also don't forget slopes with decrease are negative slopes and slopes with increase are positive slopes. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right. It's important to note that we work from left to right when dealing with slope.
The graph of a linear equation is a straight line.
The quantity that represents the cost per square yard of carpeting is the (a) slope of the graph.
The slope of the graph is the rate of change of the total cost over the change in square yard.
This means that:
The slope of the graph is the cost per square yard of the carpet.
Hence, the required quantity is (a)

Answer:
Area: [tex]5x[/tex], Perimeter: [tex]2x+10[/tex]
Step-by-step explanation:
a)
We know that for any rectangle the area is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the area is [tex]x*5[/tex] or [tex]5x[/tex].
b)
We know that for any rectangle the perimeter is [tex]2(l+w)=l+w+l+w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the perimeter is [tex]2(x+5)=2x+10[/tex].
So, the answers are [tex]Area:5x,~Perimeter:2x+10[/tex]

Write a two-column proof.
Given m<4 =35, m<1= m<2 + m<4.
Prove m<3 = 70
Answer:
given m<4 = 35° and m<1 = m<2 + m<4
prove m<3 = 70°
Statements Reasons
m<4 = 35° given
m<1 = m<2 + m<4 given
m<2 = m<4 by the vertical angles theorem
35° = 35° substitution property of equality
m<2 + m<4 = m<1 angle addition postulate
35° + 35° = 70° substitution property of equality
m<3 = m<1 by the vertical angles theorem
m<3 = 70° substitution property of equality
The two column proof for the given set of angles are:
m∠2 = m∠4 by the vertical angles theorem
m∠3 = m∠1 by the vertical angles theorem
Given data:
The measure of angle
The measure of angle m∠4 =35,
The measure of angle m∠1= m∠2 + m∠4.
Now, Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Therefore, m∠2 = m∠4 by the vertical angles theorem
m∠3 = m∠1 by the vertical angles theorem
35° + 35° = 70° substitution property of equality
Hence, the measure of angle m∠3 = 70°

You can use the method of calculating the percentage of an amount to find out the discount amount.
The discount price for the given condition was $205.2
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]
How to find the discount price?First we will find the marked price since the discount price was calculated on the marked price.
Since marked price was 150% of the cost price $456, thus,
[tex]\text{Marked price} = \dfrac{456}{100} \times 150 = \$684[/tex]
Thus, the marked price of the furniture was $684
Now, since the discount offered on the price was 30%, thus,
[tex]Discount = \dfrac{\text{Marked price}}{100} \times \text{Discount percent} =\dfrac{684}{100} \times 30\\\\Discount = \$205.2[/tex]
Thus,
The discount price for the given condition was $205.2

Options D and E are out because it clearly says " bags can only carry up to 480 pound" and those are saying it can hold more than 480
Options B and C have a dashed line. If it has a dashed line that means that it is < or > and it is not because it says "up to" up to means it CAN hold exactly 480
