Area of figure = area of trapezoid + area of rectangle

A(rectangle) = 18 x 5 = 90 cm2
A(trapezoid) = (10+18) x (13-5) : 2 = 112 cm2

A(figure) = 112 + 90 = 202 cm2

Answer:

p = 23

q = 18

Step-by-step explanation:

The four interior angles of a square are all 90° each

 4p - 2 = 90

⇒ 4p = 92

⇒ p = 92 ÷ 4

⇒ p = 23

 5q = 90

⇒ q = 90 ÷ 5

⇒ q = 18

Answer:

p=23; q=18.

Step-by-step explanation:

1) m∠(XWZ)=90, then 4p-2=90 and p=23°;

2) m∠(WZY)=90, then 5q=90 and q=18°.

Answer:

(√3 - x)(√3 + x)

Step-by-step explanation:

Use difference of two square formula:

a² - b² = (a - b)(a + b)

So a² = 3  ⇒  a = √3

and  b² = x²  ⇒  b = x

Therefore, 3 - x² = (√3 - x)(√3 + x)

Answer:

[tex]y=\dfrac{2xz}{(z-x)}[/tex]

Step-by-step explanation:

Given:

[tex]\dfrac{1}{x}=\dfrac{2}{y}+\dfrac{1}{z}[/tex]

[tex]\implies \dfrac{2}{y}=\dfrac{1}{x}-\dfrac{1}{z}[/tex]

[tex]\implies \dfrac{2}{y}=\dfrac{z-x}{xz}[/tex]

[tex]\implies 2xz=y(z-x)[/tex]

[tex]\implies y=\dfrac{2xz}{(z-x)}[/tex]

When x = 5 and z = 10:

[tex]\implies y=\dfrac{2(5)(10)}{(10-5)}[/tex]

[tex]\implies y=\dfrac{100}{5}[/tex]

[tex]\implies y=20[/tex]

Answer: 12

Step-by-step explanation:

to find this, divide 4 by 1/3:

4/(1/3) = 4x3 = 12

there are 12 1/3 cup servings in 4 cups

Answer:

Hey there!

Contains 4 cups of trail mix

He wants 1/3 go cup servings

=> 4 ÷ 1/3

=> 4×3/1

=> 12

Therefore, there are 12 of 1/3 in 4 cups

Answer:

9c^2 - 30cd + 25d^2

Step-by-step explanation:

(3c - 5d)^2

= (3c - 5d) (3c - 5d)

= [3c * 3c] + [3c * -5d] + [-5d * 3c] + [-5d * -5d]

= 9c^2 - 30cd + 25d^2

Summing all the ingredients to get the total sample size, we applied the formula for obtaining the probability which is

Pr(3) = 0.5

Given Data

Sample Space

Total Sample size = 6

Probability of identifying 3 ingredient used is

Pr(3) = 3/6

Pr(3) = 1/2

Hence the Probability is 0.5

The total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.  

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

She keeps some in a display case and the rest on the wall. 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Let x be the total number of toy cars in Enola's collection:

69% of x = x - 155

0.69x = x - 155

0.31x = 155

x = 500

Thus, the total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Answer:

15x^3y+6x^2y^2+9xy^3

Step-by-step explanation:

3xy ( 5x^2 +2xy +3y^2)

Distribute the 3xy to all terms in the parentheses

3xy*5x^2+3xy*2xy+3xy*3y^2

15x^3y+6x^2y^2+9xy^3

Answer:

15[tex]x^{3}[/tex]y + 6[tex]x^{2}[/tex][tex]y^{2}[/tex] + 9x[tex]y^{3}[/tex]

Step-by-step explanation:

multiple everything in the brackets by 3xy

3xy x 5[tex]x^{2}[/tex] = 15[tex]x^{3}[/tex]y

3xy x 2xy = 6[tex]x^{2}[/tex][tex]y^{2}[/tex]

3xy x 3[tex]y^{2}[/tex] = 9x[tex]y^{3}[/tex]

15[tex]x^{3}[/tex]y + 6[tex]x^{2}[/tex][tex]y^{2}[/tex] + 9x[tex]y^{3}[/tex]

Step-by-step explanation:

All we have to do is apply the Pythagorean theorem which states that a²+b²=c²

where c is the hypotenuse of the triangle or the side facing the 90° angle.

Moreover a & b are the other two sides of the triangle.

[tex]11 {}^{2} = {9}^{2} + h {}^{2} [/tex]

where h is the height from the ground

[tex]121 = 81 + {h}^{2} [/tex]

[tex]h {}^{2} = 121 - 81[/tex]

[tex]h {}^{2} = 40[/tex]

[tex]h = \sqrt{40} = 6.324[/tex]

Rounding to the nearest tenth,

[tex]h = 6.3[/tex]

[tex]\begin{cases} x=-5\implies &x+5=0\\ x=3\implies &x-3=0 \end{cases}\qquad \implies \underline{a(x+5)(x-3)~~ = ~~\stackrel{0}{y}} \\\\\\ \stackrel{\textit{we also know that}}{P(0)=-30}\implies \begin{cases} x=0\\ y=-30 \end{cases}\implies a(0+5)(0-3)~~ = ~~-30 \\\\\\ a(5)(-3)=-30\implies -15a=-30\implies a=\cfrac{-30}{-15}\implies \boxed{a=2} \\\\[-0.35em] ~\dotfill\\\\ 2(x+5)(x-3)=y\implies 2(\stackrel{F~O~I~L}{x^2+2x-15})=y\implies \underline{2x^2+4x-30=y}[/tex]
