The square root is 5 units.
Step-by-step explanation:
It is given that:
Square area is 25 units square.
We have to find the square root.
Square root = [tex]\sqrt{25}[/tex]
Square root = [tex]\sqrt{5*5}[/tex]
Square root = 5 units
Therefore,
The square root is 5 units.

The ratio of males to females in a cycling club is 5:3.
1/3 of the males are under 18
2/9 of the females are under 18
What fraction of the club members are under 18? Give your answer in its simplest form.
Answer:
3/2
Step-by-step explanation:
The ratio of males to females in a cycling club is 5:3.
1/3 of the males are under 18
2/9 of the females are under 18
The fraction of the club members that are under 18 is calculated as:
Male: Female = Male/Female
We are told in the above question:
1/3 of the males are under 18
2/9 of the females are under 18
Hence:
1/3 / 2/9
= 1/3 ÷ 2/9
= 1/3 × 9/2
= 3/2
The fraction of the club members that are under 18 is 3/2

What is the slope of the line that passes through the points (3, –1) and (–2, –5)?
Show Work
write the equation of the line in y=mx+b that passes through the points (5,10) and (6,12)
Write your answer as a simplified fraction.
Answer:
y = 2x + 0 or y = 2x
Step-by-step explanation:
use slope-intercept form [tex]\frac{y2 - y1}{x2 - x1}[/tex]
12 - 10 = 2
6 - 5 = 1
m value = 2/1 = 2
y=2x+b
to find b plug one of the points in for x and y
Example: 10 = 2(5) + b
solve equation
10 = 10 + b
subtract 10 from both sides
0 = b
Equation of line equals y=2x+0 or simply just y=2x
What is (6x+4) - (4x+2)
Answer:
x = -1
Step-by-step explanation:
1. Simplifying
6x + 4 = 4x + 2
2. Reorder the terms
4 + 6x = 4x + 2 to 4 + 6x = 2 + 4x
3. Solving
4 + 6x = 2 + 4x
4. Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right. Then add '-4x' to each side of the equation.
4 + 6x + -4x = 2 + 4x + -4x
5. Combine like terms: 6x + -4x = 2x
4 + 2x = 2 + 4x + -4x
6. Combine like terms: 4x + -4x = 0
4 + 2x = 2 + 0
4 + 2x = 2
7. Add '-4' to each side of the equation.
4 + -4 + 2x = 2 + -4
8. Combine like terms: 4 + -4 = 0
0 + 2x = 2 + -4
2x = 2 + -4
9. Combine like terms: 2 + -4 = -2
2x = -2
10. Divide each side by '2'.
x = -1
11. Simplifying
x = -1
TJ makes a salary of $400 a week. He also
makes a commission of 15% off of
everything he sells for the week. If his total
sales are $15,000, what is his total pay for
the week?
Answer:
Step-by-step explanation:
If TJ made 15,000 dollars in a week, with the 15% commission,
15,000*15/100=2,250 in commission
2250+400=2650 salary for that week
If 6x – 10y
9 is a true equation, what would be the value of -18x + 30y?
Answer:
The value of -18x + 30y is -27
Step-by-step explanation:
Algebraic Expressions
It's given that:
6x - 10y = 9
We are required to find the value of
-18x + 30y
The easiest way to solve the problem is to visualize that:
-18x = -3(6x)
30y = -3(-10y)
This means that the second expression is equal to the first expression multiplied by -3, thus:
-18x + 30y = -3(6x - 10y) = -3*9 = -27
The value of -18x + 30y is -27

Answer:
Smallest surface area is of Cuboid B i.e 440 cm²
So, The company will choose cuboid B
Step-by-step explanation:
We need to find the surface area of all cuboids.
Surface Area of Cuboid A:
Length = 6
Breadth = 25
Height = 4
The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]
Putting values and finding surface area:
[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2((6 \times 25)+(25 \times 4)+(6 \times 4))\\Surface \ Area \ of \ Cuboid=2(150+100+24)\\Surface \ Area \ of \ Cuboid=2(274)\\Surface \ Area \ of \ Cuboid=548\: cm^2[/tex]
So, Surface Area of Cuboid A = 548 cm²
Surface Area of Cuboid B:
Length = 10
Breadth = 6
Height = 10
The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]
Putting values and finding surface area:
[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2(10 \times 6)+(6 \times 10)+(10 \times 10))\\Surface \ Area \ of \ Cuboid=2(60+60+100)\\Surface \ Area \ of \ Cuboid=2(220)\\Surface \ Area \ of \ Cuboid=440\: cm^2[/tex]
So, Surface Area of Cuboid B = 440 cm²
Surface Area of Cuboid C:
Length = 2
Breadth = 20
Height = 15
The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]
Putting values and finding surface area:
[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2((2 \times 20)+(20 \times 15)+(2 \times 15))\\Surface \ Area \ of \ Cuboid=2(40+300+30)\\Surface \ Area \ of \ Cuboid=2(370)\\Surface \ Area \ of \ Cuboid=740\: cm^2[/tex]
So, Surface Area of Cuboid C = 740 cm²
So, We get:
Surface Area of Cuboid A = 548 cm²
Surface Area of Cuboid B = 440 cm²
Surface Area of Cuboid C = 740 cm²
The company wants to choose the design having smallest surface area.
So, smallest surface area is of Cuboid B i.e 440 cm²
So, The company will choose cuboid B

A skier is on the top of a 350 meter tall mountain looking down at a tree. The direct path from the tree to the skier is 505 meters. What is the angle of depression from where the skier is standing to the base of the tree
Answer:
[tex]43.87^{\circ}[/tex]
Step-by-step explanation:
We are given that
Height of mountain=350 m
Distance from the tree to the skier=505 m
We have to find the angle of depression from where the skier is standing to the base of the tree.
In triangle ABC
[tex]\frac{AB}{AC}=sin\theta[/tex]
By using the formula
[tex]\frac{Perpendicular\;side}{Hypotenuse}=sin\theta[/tex]
[tex]\frac{350}{505}=sin\theta[/tex]
[tex]sin^{-1}(\frac{350}{505})=\theta[/tex]
[tex]\theta=43.87^{\circ}[/tex]
Hence, the angle of depression from where the skier is standing to the base of the tree=[tex]43.87^{\circ}[/tex]

HELP ASAP Name an angle supplementary to angle5
Answer:
Angle 1
Step-by-step explanation:
The angle supplementary to 5 is 1 because two angles are supplementary when they add up to 180 degrees.
So therefore, on the other/opposite side of angle 5 is angle 1.
The supplementary angle to ∠5 is D. ∠6 as the sum of this two angles is 180°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know two angles are supplementary if the sum of their measure is 180°.
Now, From the given diagram we can conclude that a straight line is forming with ∠5 and ∠6, So the sum of these angles must be 180° hence supplementary.
Therefore, The angle supplementary to ∠5 is ∠6.
