Answer:

On the first page: The two trapezoids on the left are similar.

On the second page: The two rectangles on the right are similar.

Step-by-step explanation:

Similar shapes have corresponding sides in a constant proportion.

The trapezoids on the left of the first page have a scale factor of 2.5 between the smaller and larger trapezoid between all corresponding sides, therefore are similar.

The rectangles on the right of the second page have a scale factor of 1.6 between the smaller and larger rectangle between all corresponding sides, therefore are similar.

What is the perimeter of the triangle? Round to the nearest tenth.

Cerrena [4.2K]

Answer: 19.8 Units

Step-by-step explanation:

The triangle is shown in the attached figure, and have three vertices: $AB$ , $AC$ and $BC$ .

Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.

In this sense, the modulus $m$ is calculated as shown:

$m=\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}$

Hence, for each vector:

$AB=\sqrt{(-2-3)^{2} + (3-0)^{2}}=\sqrt{34}$

$AC=\sqrt{(-2-(4))^{2} + (3-(-3))^{2}}=\sqrt{40}$

$BC=\sqrt{(-4-3)^{2} + (-3-0)^{2}}=\sqrt{58}$

Now, the perimeter of a triangle is the sum of its three sides:

$AB+AC+BC=\sqrt{34} + \sqrt{40} + \sqrt{58}$

Finally:

$AB+AC+BC=19.77 \approx 19.8$

The perimeter of a rectangular closet is 24 feet. The closet is 3 feet wide. How long is it?

Dima020 [189]

Answer:

9 feet

Step-by-step explanation:

The perimeter of a rectangle is 2(l + w) = p, where l = length, w = width, and p = perimeter.

In this case, we're given the values of the width and perimeter: 2(l + 3) = 24

We can solve this equation algebraically!

Step 1: Distributive the 2 to the terms inside the parentheses.

$(2)(l) + (2)(3) = 24$
$2l + 6 = 24$

Step 2: Subtract 6 from both sides.

$2l + 6 - 6 = 24 - 6$
$2l = 18$

Step 3: Divide both sides by 2.

$2l/2 = 18/2$
$l = 9$

Therefore, the length is 9 feet.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

If an object is dropped from a height of 178 feet, the function h(t)=-16t^2+178 gives the height of the object after t seconds.

svp [43]

Answer:

B. 3.34s

Step-by-step explanation:

Find t when the object hit the ground, h(t)=0.

h(t)=-16t²+178

0=-16t²+178

16t²=178

t²=11.125

t=√11.125=3.33541601603s
