Answer:

Width = 5 ft

Step-by-step explanation:

A=wl

10 = wl

24 inches = 2 ft

10 = [tex]w*2[/tex]

[tex]10/2=w*2/2\\5=w[/tex]

Answer:

x = 20

Step-by-step explanation:

The sum of the two angles is 90 degrees

x+3x+10 = 90

Combine like terms

4x+10 = 90

Subtract 10 from each side

4x+10-10 = 90-10

4x= 80

Divide each side by 4

4x/4 = 80/4

x = 20

Answer:

x = 20

Step-by-step explanation:

x and 3x + 10 form a right angle, then

x + 3x + 10 = 90

4x + 10 = 90 ( subtract 10 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20

-1

Step-by-step explanation:

slope (m)= y2- y1/ x2-x1

Answer:

Number of students who got grade A = [tex]\frac{8y}{x}[/tex]

Step-by-step explanation:

Number of students who got grade B = 8

Ratio of the students that got A to the students who got B = [tex]y:x[/tex]

That is

Number of students who got grade A : Number of students who got grade B =  

[tex]y:x[/tex]

Number of students who got grade A : 8 = [tex]y:x[/tex]

Therefore,

Number of students who got grade A = [tex]\frac{8y}{x}[/tex]

Answer:

angle x = 28 degrees

Step-by-step explanation:

Because of vertical angles, angle IAK and angle BAC are equal, and angle GCJ and angle ACB are also equal due to vertical angles

Since KL is perpendicular to FG, angle ABC is 90 degrees

ABC is a right triangle and acute angles in a right triangle are equal to 90 degrees

This means that angle BAC + angle ACB = 90 degrees

angle BAC = 62 degrees and angle ACB = x degrees

62 + x = 90

x = 28 degrees

Step-by-step explanation:

Answer:

The equation that models the amount of money she could raise is written as:

t = 25c

Step-by-step explanation:

Rachel is selling gift cards to raise money for her swim team. Each gift card costs $25.00. If c represents the number of gift cards she sells, , which equation models the amount of money she could raise?

Let t represent the total amount collected

Each gift card costs $25.00.

If c represents the number of gift cards she sells

The equation that models the amount of money she could raise is written as:

t = $25 × c

t = 25c

Answer:

sin(A) = 16*Cos(A)/63

Step-by-step explanation:

You didn't state what quadrant it was in.

The sine of angle A is 16 / 65

In a right-angled triangle, the sine of an angle is equal to the ratio of the side opposite to the angle (also called perpendicular) and hypotenuse.

Give that, cot A = 63/16 and that angle A is in Quadrant, (refer to the figure attached)

Since, we know that, cotangent of an angle is ratio of adjacent side to opposite side.

Using Pythagoras theorem, we get,

63²+16² = 4255

√4225 = 65

Therefore, the hypotenuse = 65

sine of an angle = opposite side / hypotenuse

sinA = 16 / 65

Hence, the sine of angle A is 16 / 65

Answer:

x=15

Step-by-step explanation:

If one side is 45, other side has to be 45 as well.

3x = 45

x = 45/3

x = 15

Answer:

90

Step-by-step explanation:

Partition the figure by extending the sides of the ``middle'' square as shown at the right. Each original square contains four $3 \times 3$ small squares. The shaded figure consists of ten $3 \times 3$ squares, so its area is $10 \times 9 = \boxed{90\text{ square

units}}$.

In this exercise we have to use the knowledge of areas to calculate the area of ​​the square in gray, so we have that:

[tex]A=90[/tex]

First it is informed that one side of the square is 6, so every square has exactly:

[tex]l^2=6^2=36[/tex]

Adding that we have 3 squares with the same value of sides:

[tex]36*3=108[/tex]

However, there are areas that are being calculated twice in the central square, these areas are smaller squares that have side values ​​equal to 3, so:

[tex]l^2=3^2=9\\9*2=18\\108-18=90[/tex]

Answer:

15 students at school

Step-by-step explanation:

So there is 50 students in total

First subtract that much with how much students have the flu

1/10 = 5/50

So 5 students have the flu

That leaves 45 students

Then subtract that much with the amount of students that are remaining are on the field trip

45 divided by 3 = 15

so 2/3 = 30/45 (they can both be multiplied and divided by 15)

so 30 of the 45 students are on the field trip

45 - 30 = 15

That means there are 15 students left over at school
