A rectangular prism has a lenght of 8 inches and a width of 7 inches. The lateral area is 150 square inches . What is the height of the prism?
Answers
If a rectangular prism has a lenght of 8 inches and a width of 7 inches. The lateral area is 150 square inches then the height of the rectangular prism is 5 inches.
To find the height of the rectangular prism, we'll first find the formula for the lateral area of a rectangular prism and then solve for the height using the given lateral area.
The lateral area of a rectangular prism is given by the formula:
[tex]\[ \text{Lateral Area} = 2 \times (\text{Length} \times \text{Height} + \text{Width} \times \text{Height}) \][/tex]
Given that the length is 8 inches, the width is 7 inches, and the lateral area is 150 square inches, we can substitute these values into the formula and solve for the height:
[tex]\[ 150 = 2 \times (8 \times \text{Height} + 7 \times \text{Height}) \][/tex]
[tex]\[ 150 = 2 \times (8\text{Height} + 7\text{Height}) \][/tex]
[tex]\[ 150 = 2 \times 15\text{Height} \][/tex]
Divide both sides by 2:
[tex]\[ 75 = 15\text{Height} \][/tex]
Now, solve for the height:
[tex]\[ \text{Height} = \frac{75}{15} \][/tex]
[tex]\[ \text{Height} = 5 \text{ inches} \][/tex]
So, the height of the rectangular prism is 5 inches.

16(x-8)(x-7)
x1=8/1= 8
x2= 7/1= 7
The answer would be A) x = 7 or x = 8
Answer:
The correct answer is A).
Step-by-step explanation:
He have the quadratic functions f(x) = 16x²-240x+896. The first step should be to check if the coefficients 240 and 896 are divisible by 16, which is true. Then, extracting 16 as common factor we have
f(x) = 16(x²-15x+56).
Now we can use directly the formula to find the roots of a quadratic equation, or a more efficient way in terms of calculations. We must find to numbers such that their product is +56 and their addition or subtraction is -15. It is not difficult to check that -7 and -8 fulfill those conditions. Hence,
f(x) = 16(x²-15x+56)= 16(x-7)(x-8).
Therefore, the solutions are x=8 and x=7.
3. Janet is flying a kite on a string that is 75m long. The kite is 62m above the ground. Estimate the distance between Janet and the spot on the ground directly beneath the kite.
(a) Draw a diagram showing Janet and the kite.
(b) What is the length of the string of the kite?
Answer:
Answers
For this, you will need to draw your own diagram, but I think you can do this if I explain it. It should look like a triangle. Where the string is a vertex, and the kite is an upper vertex. The bottom is the distance. Look at the example. You can label the distances on it if you want to.
c= length of the string (75m)
b= height of the kite (62m)
a will equal the distance between Janet and the spot on the ground beneath the kite.
Now, we plug it into the Pythagorean theorem.
a^2+b^2= c^2
a^2+ 62^2= 75^2
Square the numbers.
a^2+3844= 5625
Subtract 3844 on both sides.
a^2= 1781
Find the square root.
√1781= 42.2 or 42.

Robin earned $4,320 in 9 weeks and worked 40 hours in each week. How much did he earn per hour? $ per hour
Answers
Answer:
$12 per hour
Step-by-step explanation:
To solve how much did Robin earned per hour you just have to do a simple equation, we know that he worked 9 weeks, and that each week he worked 40 hours, so you equation would look like this:
[tex]Income=(wageperhour)*(hours worked)[/tex]
The hours worked is just a math done by multiplying the weeks worked by the hours worked per week that would be:
[tex]Hours worked=Hours worked per week*weeks\\Hours worked=(40 hours)*(9 weeks)\\Hours worked=360 hours[/tex]
So now we just put the data into our equation
[tex]Income=(wageperhour)*(hours worked)\\$4320=(wageperhour)*(360)\\wage per hour=4320/360\\ Wage per hour= 12[/tex]
Dominic is building a bench with a seat in the shape of a trapezoid. One base is 5 feet. The other base is 4 feet. The perpendicular distance between the bases is 2.5 feet. what is the area of the seat
Answers
A = [(b1 + b2) x h] / 2
Where,
b1: Base 1
b2: Base 2
h: height, or distance between bases.
Substituting we have:
A = ((5 + 4) * (2.5)) / 2
A = 11.25 feet ^ 2
Answer:
the area of the seat is:
A = 11.25 feet ^ 2
The area of Dominic's trapezoid-shaped bench seat is 11.25 square feet. This is calculated using the trapezoid area formula with given bases of 5 and 4 feet and a height of 2.5 feet.
To find the area of the seat of Dominic's bench, which is in the shape of a trapezoid, we use the formula for the area of a trapezoid:
Area = 1/2 × (Base1 + Base2) × Height
In this case:
Base1 (b1) = 5 feetBase2 (b2) = 4 feetHeight (h) = 2.5 feetSubstitute these values into the formula:
Area = 1/2 × (5 + 4) × 2.5
Area = 1/2 × 9 × 2.5
Area = 4.5 × 2.5
Area = 11.25 square feet
Thus, the area of the trapezoid-shaped seat is 11.25 square feet.

Step-by-step explanation:
Luis skates 2/3 mile from his home to school. Isabella skates 2/4 mile to get to school. Who skates father?
Answers
The least common denominator of 3 and 4 is 12. This means that we have to change both fractions into equal fractions with denominators of 12.
To figure this out, we must set up a proportion.
2/3 = x/12
To solve this proportion, we must cross-multiply the fractions. We get:
24 = 3x
If we divide both sides by the coefficient of x which is 3, to get the variable x alone, we get:
x = 8
Therefore, 2/3 = 8/12, so Luis skates 8/12 mile from his home to school.
If we do the same process for the 2/4 mile to get to school for Isabella, we get 6/12, because both fractions are equal to 1/2.
Therefore, we know that Luis skates 8/12 mile to school and Isabella skates 6/12 mile to get to school. Because they have the same denominator, we can just compare the numerators. We know that 8 is greater than 6, thus Luis skates farther to get to school.
Final answer:
Luis skates further to school than Isabella, as 2/3 mile is greater than Isabella's distance of 1/2 mile after simplification.
Explanation:
The question revolves around figuring out who skates further to school, Luis or Isabella. Luis skates 2/3 mile from his home to school whereas Isabella skates 2/4 mile (which can be simplified to 1/2 mile) to get to school. To determine who skates further, we look at the fraction representing the distance each person skates.
Luis's distance is 2/3 mile, and Isabella's distance, after simplification, is 1/2 mile. Since 2/3 is greater than 1/2, Luis skates further to get to school than Isabella.

175/42, 234/42.
Here are the steps to follow:
Find the Least Common Multiple of the denominators (which is called the Least Common Denominator).Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator
Then add (or subtract) the fractions, as we wish!
Hoped I helped!
The LCD of [tex]\( \frac{4}{6} \)[/tex] and [tex]\( \frac{5}{7} \)[/tex] is [tex]42[/tex]. This is because [tex]42[/tex] is the smallest number that both [tex]6[/tex] and [tex]7[/tex] divide into evenly, ensuring that [tex]\( \frac{25}{6} \)[/tex] and [tex]\( \frac{39}{7} \)[/tex] can be expressed with a common denominator of [tex]42.[/tex]
1. Convert [tex]\( 4 \frac{1}{6}[/tex] to an improper fraction:
[tex]\[ 4 \frac{1}{6} = \frac{4 \times 6 + 1}{6} = \frac{24 + 1}{6} = \frac{25}{6} \][/tex]
2. Convert [tex]\( 5 \frac{4}{7} \)[/tex] to an improper fraction:
[tex]\[ 5 \frac{4}{7} = \frac{5 \times 7 + 4}{7} = \frac{35 + 4}{7} = \frac{39}{7} \][/tex]
Now, the fractions [tex]\( \frac{25}{6} \)[/tex] and [tex]\( \frac{39}{7} \)[/tex] need to have a common denominator to find the LCD.
Finding the Least Common Denominator (LCD)
To find the LCD, we need to determine the least common multiple (LCM) of the denominators [tex]6[/tex] and [tex]7[/tex]
The prime factorization of [tex]6[/tex] is [tex]\( 2 \times 3 \).[/tex]
The prime factorization of [tex]7[/tex] is [tex]\( 7 \).[/tex]
The LCM of [tex]6[/tex] and [tex]7[/tex] is [tex]\( 6 \times 7 = 42 \).[/tex]
Verify and Convert to Common Denominator:
Convert both fractions to have a denominator of [tex]42[/tex]
[tex]\[ \frac{25}{6} \times \frac{7}{7} = \frac{175}{42} \][/tex]
[tex]\[ \frac{39}{7} \times \frac{6}{6} = \frac{234}{42} \][/tex]
Now, [tex]\( \frac{25}{6} \) converts to \( \frac{175}{42} \) and \( \frac{39}{7} \) converts to \( \frac{234}{42} \).[/tex]

If r=4 units and x = 8 units then what is the volume of the cylinder shown above use 3.14 for TT and round your answer to the nearest hundredth
Answers
Note: It does not say that x is the height, but this is the only piece of information missing without an obvious label, so I am using it as the height.
Final answer:
The volume of a cylinder with a radius of 4 units and a height of 8 units is 401.92 cubic units, calculated using the formula V = πr²h and rounding to the nearest hundredth.
Explanation:
Calculating the Volume of a Cylinder
To find the volume of a cylinder, we can use the formula V = πr²h, where 'V' represents the volume, 'r' is the radius, and 'h' is the height of the cylinder. Since you have provided that the radius (r) is 4 units and the height (x) is 8 units, we can substitute these values into the formula as follows:
V = 3.14 × (4 units)² × 8 units
First, we calculate the radius squared (4 units)²:
(4 units)² = 16 units²
Now we multiply this by the height and π as given:
V = 3.14 × 16 units² × 8 units
V = 3.14 × 128 units³
V = 401.92 units³
Therefore, the volume of the cylinder is 401.92 cubic units, rounded to the nearest hundredth.

Answers
The Putri turned 36 degrees to her left should she turn before walking home if Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
The total distance between cave to home AC = 3.72 km
The distance she walks AB = 2.60 km
The angle of turn = 58°
As we can see in the triangle ABC we can apply the sin law:
[tex]\rm \frac{AB}{sinx} = \frac{AC}{sin58\°}[/tex]
[tex]\rm \frac{2.6}{sinx} = \frac{3.72}{sin58\°}[/tex]
sinx = 0.5927
x = 36.35 ≈ 36°
Thus, the Putri turned 36 degrees to her left should she turn before walking home if Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.

Putri should turn 122 degrees to her left when facing the big rock to head back to her home. This direction aligns her with the original path she took to reach the cave.
To determine the number of degrees to her left Putri should turn, we need to analyze her movements using the angles involved.
Putri starts by walking 2.60 kilometers in a straight line.She spots the cave after climbing the rock and turns 58 degrees to the right of her original path.This new path takes her directly to the cave, which is a straight-line distance of 3.72 kilometers from her home.When Putri is in the cave facing the large rock, to get back to her home, she needs to turn in the opposite direction of her initial right turn:
Initially, she turned 58 degrees to the right.Facing the rock, she must turn 180 degrees - 58 degrees = 122 degrees to her left to be aligned with her starting path towards home.Putri should turn 122 degrees to her left when facing the big rock to head back to her home.

A number cube has six faces, numbered 1 to 6. John tossed two number cubes several times and added the numbers each time
Answers
John adds the outcomes of rolling two dice each showing numbers 1-6. In total, there are 36 possible outcomes when rolling two dice. The totals of the outcomes range from 2 to 12, with varying probabilities of each total.
Explanation:John's activity involves the mathematical operation of adding the outcomes of two number cubes, also known as six-sided dice. Each die has six faces, numbered from 1 to 6. When you roll two dice, there are 36 possible outcomes (6 options from the first die multiplied by 6 options from the second die).
For example, the dice could both show a 1, both show a 2, and so on up to 6. Alternatively, they could show different numbers, like 1 and 2, 1 and 3, up until 5 and 6. If you list all 36 possibilities and add up the numbers shown on the dice for each possibility, you'll get every total from 2 to 12.
Each total has a certain probability of occurring, based on how many of the 36 possibilities will result in that total.
For example, there's only one way to get a total of 2 (both dice showing 1), but there are several ways to get a total of 7 (1 and 6, 2 and 5, 3 and 4, 4 and 3, 5 and 2, 6 and 1).Learn more about Probability here:https://brainly.com/question/22962752
