Answer:

The correct option is D.

Step-by-step explanation:

Given information:

Length of the poster = \frac{9}{2} ft

Area of the poster = \frac{45}{4} ft²

We need to find the width of the poster.

The area of a rectangular poster is

A=l\times w

where, l is length and w is width.

Substitute A=\frac{45}{4} and  l=\frac{9}{2} in the above formula.

\frac{45}{4}=\frac{9}{2} \times w

\frac{45}{4}=\frac{9w}{2}

On cross multiplication we get

45\times 2=9w\times 4

90=36w

Divide both sides by 36.

\frac{90}{36}=w

Cancel out common factors.

\frac{5}{2}=w

The width of the poster is 5/2 ft.

Therefore the correct option is D.

a triangle has side lengths of (2.9n-7.8p)(2.9n−7.8p) centimeters, (6.6n-6.4q)(6.6n−6.4q) centimeters, and (2.9q-3.8p)(2.9q−3.8p

The perimeter of the triangle is: (9.5n - 11.6p - 3.5q) cm.

<h3>What is the Perimeter of a Triangle?</h3>

The total length of all the sides of a triangle is equal to the perimeter of the triangle.

Given a triangle has the following lengths:

  • (2.9n-7.8p) centimeters,
  • (6.6n-6.4q) centimeters,
  • (2.9q-3.8p) centimeters.

The perimeter of the triangle = (2.9n-7.8p) + (6.6n-6.4q) + (2.9q-3.8p)

The perimeter of the triangle = 2.9n - 7.8p + 6.6n - 6.4q + 2.9q - 3.8p

Combine like terms together

The perimeter of the triangle = 2.9n + 6.6n - 7.8p - 3.8p - 6.4q + 2.9q

The perimeter of the triangle = 9.5n - 11.6p - 3.5q

Thus, the perimeter of the triangle is: (9.5n - 11.6p - 3.5q) cm.

Kaitlyn saves $6 each week. After correctly carrying out the Solve step of the five-step problem-solving plan, which solution sh
ch4aika [34]

Answer:

1. 10 weeks

Step-by-step explanation:

Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.

... $6 × w = $60

Divide by $6 to get ...

... w = $60/$6 = 10

Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

_____

<em>Comment on the problem statement</em>

The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)

Need help fast right now. Find the surface area of each solid. Round to the nearest tenth of necessary.
Mice21 [21]

Answer:

5)surface =2(lb*bh*hl)

=2(12*4+4*4+4*12)

=2(48+16+48)

=2(96+16)

=2*112

=224inc^2

6)surfacearea=2*pi*r(r+h)

=2*3.14*2(2+1)

=6.28*2*3

=6.28*6

=37.68m^2

What is the rang for the equation y=2x-3​
a_sh-v [17]

Answer:

The range for the equation is all real numbers.

Step-by-step explanation:

The range of an equation is the set of y-values that you can get by plugging in all possible x-values.

Another way to put it is, when you graph the equation, whatever y-values the line produces, is its range.

Graphing y=2x-3, you can see it is a graph with a positive slope that extends from negative infinity y-value to positive infinity x-value.
