Answer:

52%

Step-by-step explanation:

There are 25 filled in squares in the first image, and 13 filled in squares in the second image.

To find the percentage we can divide the part of the base (a) by the base (b).

a = 13

b = 25

13/25 = 0.52

Move the decimal two places over to the right.

Answer:

Step-by-step explanation:

Let Kayla made number of 2 points shots = x

and the number of 3 points shots = y

Since she made total nine shots so the equation will be

x + y = 9 --------(1)

She scores a total of 22 points so the equation will be

2x + 3y = 22 --------(2)

Now we multiply equation (1) by 2 and subtract it from equation (2)

(2x + 3y) - 2(x + y) = 22 - 18

2x + 3y - 2x - 2y = 4

y = 4

from equation (1)

x + 4 = 9

x = 5

Therefore, number of 2 shots are 5 and number of 3 shots are 4.

Answer:

The area of the circular park is about 1017.88

Step-by-step explanation:

First, we recall the area of a circle.

A=  πr^2

Next, we plug in the radius

A=  π*18^2

A=  π*324

A= 1017.88

To conclude, that is how you find the area of a circular park.

Answer:

2 2/3

Step-by-step explanation:

Since we only know how much milk we have we will disregard the flour. That leaves us with 4 cups of milk total and 1 1/2 cups of milk per serving. Simply divide 4 by 1 1/2 to get your answer of 2 2/3. Now, if they only want full servings, then the answer would be 2.

Answer:

x = 29

Angle C = 93°

Step-by-step explanation:

Since all of the interior angles of a triangle add up to 180° and we are given the values of angle A and angle B, we can find angle C by subtracting A and B from 180.

35 + 52 = 87

180 - 87 = 93

Thus, the measure of angle C is 93°.

Now that we know the measure of angle C, we can determine the value of x.

Set up an equation:

3(x + 2) = 93

3x + 6 = 93

3x = 87

x = 29

Answer:

(a)  x = 29

(b) m∠C = 93°

Step-by-step explanation:

(a)  The sum of the interior angles of a triangle = 180°

⇒ m∠A + m∠B + m∠C = 180

⇒ 35 + 52 + 3(x + 2) = 180

⇒ 87 + 3x + 6 = 180

⇒ 93 + 3x = 180

⇒ 3x = 87

⇒ x = 29

(b) As x = 29

⇒ m∠C = 3(29 + 2)

⇒ m∠C = 3 x 31

⇒ m∠C = 93°

Answer:

-9, -8.2, -4, 6, 1 3/4

Step-by-step explanation:

The larger the number is if it's a negative, the lower it is (if that makes sense). For example, -9 is lower than -7.

1 3/4 = 1.75

Answer: 1

Step-by-step explanation:

tan(15) * cos(15)/sin(15)

Use tan(x) = sin(x)/cos(x) to transform the expression:

= sin(15)/cos(15) * cos(15)/sin(15)

Cancel opposite terms on both sides:

= 1

Answer:

Step-by-step explanation:

Here it's given that a 6m ladder is leaned against a house, and the base of ladder is 2m away from the foot of the house. Here I am assuming x to be the height of the house.

Diagram :-

[tex] \begin{picture}(3,3)\setlength{\unitlength}{1cm} \linethickness{.6mm}\put(0,0){\line(1,0){4}}\put(0.01,0){\line(4,3){4}}\put(4,0){\line(0,1){3}}\put(4.3,1){$\bf x $} \put(2,-0.5){$\bf 2m$}\put(1,1.5){$\bf 6m$}\put(.9,0.2){$\bf\theta $}\put(2,4){$\boxed{\sf - RISH4BH }$}\end{picture} [/tex]

Using, Pythagoras theorem ,

[tex]\longrightarrow h^2=p^2+b^2 [/tex]

Substitute,

[tex]\longrightarrow (6m)^2=x^2+(2m)^2[/tex]

Simplify,

[tex]\longrightarrow 36m^2= x^2+4m^2 [/tex]

Subtracting 4m² on both sides,

[tex]\longrightarrow x^2 = 36m^2 -4m^2=32m^2 [/tex]

Put square root on both sides,

[tex]\longrightarrow x =\sqrt{32m^2}[/tex]

Simplify,

[tex]\longrightarrow \underline{\underline{ x = 5.65\ m}}[/tex]

Again in order to find out the angle of elevation,

[tex]\longrightarrow cos\theta =\dfrac{b}{h} [/tex]

Substitute,

[tex]\longrightarrow cos\theta =\dfrac{2m}{6m}[/tex]

Simplify,

[tex]\longrightarrow cos\theta =\dfrac{1}{3} [/tex]

Take cos inverse both sides,

[tex]\longrightarrow \underline{\underline{\theta =cos^{-1}\bigg(\dfrac{1}{3}\bigg)}}[/tex]

The length of the wall is 5.66m and the angle of elevation is 70.56°

Data;

To calculate the length of the wall or side of the house, we have to use Pythagorean theorem which is given as

[tex]x^2 = y^2 + z^2[/tex]

Let's substitute the values and solve for the length of the wall

[tex]x^2 = y^2 + z^2 \\6^2 = 2^2 + z^2 \\36 = 4 - z^2\\z^2 = 36 - 4\\z^2 = 32\\z = \sqrt{32} \\z = 5.66m[/tex]

The length of the wall is 5.66m.

To calculate the angle of elevation, we can use trigonometric ratio SOHCAHTOA

since we have the value of all the sides, we can decide to use any of the ratios.

I will use sine angle to solve for the angle of elevation.

[tex]sin \theta = \frac{opposite}{hypothenuse} \\sin \theta = \frac{5.66}{6} \\sin \theta = 0.943\\\theta = sin^-^1 (0.943)\\\theta = 70.56^0[/tex]

The angle of elevation is 70.56°

Step-by-step explanation:

The y-intercept for each line is...

y=2x+7 (0, 7)

y=2x-3 (0, -3)

y=mx+b

b represents the y-intercept

Answer:

0.4

Step-by-step explanation:

(0.2+0.3) - (0.6/6)

0.5 - 0.1

Hey there!

0.2 + 0.3 - 0.6 ÷ 6

0.2 + 0.3 = 0.50 = 0.5

= 0.5 - 0.6 ÷ 6

0.6 ÷ 6 = 0.10 = 0.1

= 0.5 - 0.1

= 0.40

= 0.4

Thus, your answer is: 0.4
