Answer:
24
Step-by-step explanation:
h(x) = [tex]\frac{1}{2}[/tex]x - 5, x < 0 This formula would be used for h(-30). Since -30 is less than 0.
h(x) = [tex]\frac{1}{2}[/tex]x - 5, x < 0 ← You can now ignore the x<0.
h(-30) = [tex]\frac{1}{2}[/tex](-30) - 5 Input the -30 as x.
h(-30) = [tex]\frac{-30}{2}[/tex] - 5 Simplify
h(-30) = -15 - 5 Simplify further
h(-30) = -20
Next
h(x) = [tex]\frac{1}{5}[/tex]x - 2, x < 0 This formula would be used for h(30). Since 30 is greater than 0.
h(x) = [tex]\frac{1}{5}[/tex]x - 2, x ≥ 0 ← You can ignore the x≥0.
h(30) = [tex]\frac{1}{5}[/tex](30) - 2 Input the 30 as x.
h(30) = [tex]\frac{30}{5}[/tex] - 2 Simplify
h(30) = 6 - 2 Simplify further
h(30) = 4
Finally the problem is asking for h(30) - h(-30) = ?
h(30) - h(-30)
(4) - (-20) Substitute the value of h(30) and the value of h(-30).
4 + 20 You distribute the - sign into the parentheses. A negative times a
24 negative is a positive. That is how the equation had become 4 + 20 towards the end. Which is equal to 24.
So the answer is 24.

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every
morning. His goal is to run at least 6 miles by the end of the week.
Which inequality represents the least number of days after Monday that Joseph needs to run
to reach his goal? *
Answers
Answer:
2 + 1 1/3x ≥ 6
x ≥ 3 days
Step-by-step explanation:
Monday = 2 miles
Other days = 1 1/3 miles
x = least number of days after Monday that Joseph needs to run
to reach his goal
Total miles = 6 miles
The inequality is
2 + 1 1/3x ≥ 6
1 1/3x ≥ 6 - 2
1 1/3x ≥ 4
4/3x ≥ 4
Divide both sides by 4/3
4/3x ÷ 4/3 ≥ 4 ÷ 4/3
x ≥ 4 × 3/4
x ≥ 3 days
(b) Give the equation of a line which is parallel to line y=2x and
passes through (0,3).
Answers
All lines parallel to y=2x-3 will have the same slope as y=2x-3. So how do you find the slope of y=2x-3? Very simple! When written in slope-intercept form you simply look at the coefficient of the ‘x’ term. In this instance the coefficient is 2. Therefore any equation that has a slope of 2 will be parallel to y=2x-3. In general we can say that the family of equations parallel to y=2x-3 is y=2x+b where b is the y-intercept.

Answer:
[tex]\text{b. }\sin \theta =\frac{3}{5}[/tex]
Step-by-step explanation:
In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\tan \theta =\frac{3}{4}[/tex] as given in the problem, then the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].
The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse. Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h).

Step-by-step explanation:
Given
[tex]Base\ Area = 200cm^2[/tex]
[tex]Volume = 3000cm^3[/tex]
Required
The height
Volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
Make Height the subject
[tex]Height = \frac{Volume}{Base\ Area}[/tex]
This gives

What is the total area, in square feet, of the house and backyard? A) 200 B) 400 C) 4,000 D) 5,200
Answers
Answer:
Area = 5200 ft²
Step-by-step explanation:
First let us find the area of the house.
Area = l × w
Area = 30 ft × 40 ft
Area = 1200 ft²
Now let us find the area of the backyard.
Area = l × w
Area = 80 ft × 50 ft
Area = 4000 ft²
Now that we have found the area of the house and the backyard, it asks us to find the total area of house and the backyard. To find the answer, you will both, the area of house and the area of the backyard.
Area of house + Area of backyard
1200 ft² + 4000 ft²
5200 ft²

Jamal's friends toss 12 balls to him at the same time. Three balls are red, 3 are green, 3 are blue, and 3 are white. Jamal manages to catch 5 of the balls.
What is the probability that he catches 2 red balls and 1 ball of each of the other colors?
Answers
Answer:
81/792 or 9/88 or 10.2%
Step-by-step explanation:
Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3
3 * 3 * 3 * 3 = 81
81/792 simplified is 9/88 percentage is 10.22%
The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lies in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total numbers of balls are 12.
Each color has 3 balls.
If total 12 balls are tossed, the number of ways of catching 5 of them is,
¹²C₅ = 792
The number of ways of catching 2 red balls out of 3 is ³C₂ = 3
The number of ways of catching 1 green ball out of 3 is ³C₁ = 3
The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3
The number of ways of catching 1 white ball out of 3 is ³C₁ = 3
Thus, the probability as per the question is given as follows,
(3 × 3 × 3 × 3)/792
= 81/792
= 0.1025
Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.
