Answer:8 ft.
Step-by-step explanation:
Given: right Δ
it's 8 because you know the triangle is a right triangle which means that you can use the Pythagorean Theorem. which would be
x²= 10²- 6²
x²= 100-36
x²=64
x=8
or you can use the Egyptian triangle which is a right triangle that's sides are equal to 3,4,5. This triangle is just double the Egyptian triangle which means everything is times 2. So knowing that and that two sides of this triangle is double two sides of the other triangle, you'll find that the third side is 8, because:
6÷3=2
10÷5=2
so now proving its double you can multiply by four by two since the answer of the previous problems is two
4×2=8

Rearrange to make x the subject
a = 7x/k -r
Help me pls
Answers
Final answer:
To make x the subject of the equation a = 7x/k - r, add r to both sides, multiply by k, and then divide by 7, resulting in x = k(a + r)/7.
Explanation:
To rearrange the equation a = 7x/k - r to make x the subject, we need to perform a series of algebraic manipulations. Firstly, we add r to both sides of the equation, giving us a + r = 7x/k. Following this, we multiply both sides by k to get rid of the denominator, which results in k(a + r) = 7x. Finally, we divide both sides by 7 to solve for x, which gives us x = k(a + r)/7. This rearrangement shows x as the subject of the original equation.

The function g(x) increases at a faster rate. The function g(x) has a greater initial value. The function g(x) decreases at a faster rate.
Answers
The functions f(x) = √16^x and g(x) = ∛64^x increase at the same rate as x increases.
Explanation:The functions f(x) = √16ˣ and g(x) = ∛64ˣ are related in the way they grow or decrease as x increases. Let's analyze each function:
For the function f(x) = √16ˣ, as x increases, the value of f(x) also increases. This is because when x increases, 16^x becomes larger, and taking the square root of a larger number results in a larger value for f(x).
For the function g(x) = ∛64ˣ, the same logic applies. As x increases, the value of g(x) also increases. This is because when x increases, 64ˣ becomes larger, and taking the cube root of a larger number results in a larger value for g(x).
Therefore, both functions f(x) and g(x) increase at the same rate as x increases. None of the given options accurately describe the relationship between the graphs of f(x) and g(x).

Answers
Answer:
It's the second choice.
Step-by-step explanation:
x + (x + 1) + (x + 2) = 30.
Solving for x will give you the smallest digit.
The equation x+(x+1)+(x+2) = 30 is used to find x.
The integers are 9, 10 & 11.
What is the required equation ?
If a, b, c are integers, then the sum of three integers is a+b+c
Let, x be a integer.
Then other two consecutive integers are, x+1 & x+2
Sum of this three integers is x+(x+1)+(x+2)
According to the question,
Sum of this three integers is 30
So, the equation becomes, x+(x+1)+(x+2) = 30
Now, solving, x+x+1+x+2 = 30
⇒ 3x+3 = 30
⇒ 3x = 27
⇒ x = 27/3 = 9
So, (x+1) = 9+1 = 10 & (x+2) = 9+2 = 11

A mason will lay rows of bricks to build a wall. The mason will spread 3/8

inches less than 4 feet high. Answer parts a and b below.
The mason wants to lay the bricks so that the shortest edge of each brick is vertical. How many rows of bricks are needed? Show your work.
Let b equal the number of rows of bricks. The total height of the bricks in inches is equal to _______ times _______
The total height of the mortar is equal to ______ times ______
Their sum is equal to the height of the wall or ______ inches.
If I write this as an equation and solve for b, then the result is ______ of bricks
Answers
Answer:
a) 18 rows of bricks are needed
b) 2.25 times b
0.375 times (b - 1)
46.875 inches
18 rows
Step-by-step explanation:
* Lets explain how to solve the problem
a)
- The height of each brick is the shortest edge
- The shortest age is 2 1/4 inch ⇒ (2.25 inches)
- If b is the number of the rows of bricks
∴ The height of the bricks = 2.35 × b
- The height of the mortar is 3/8 inches ⇒ (0.375 inch)
- All rows of bricks covered by mortar on top except the last row
- The height of mortar = 0.375 × (b - 1)
- The height of the wall is 1 1/8 (1.125) inches less than 4 feet
∵ 1 foot = 12 inches
∵ 4 feet = 12 × 4 = 48 inches
∴ The height of the wall = 48 - 1.125 = 46.875 inches
- The sum of the total height of bricks and the total height of mortar
is equal to the height of the wall
∴ 2.25 b + 0.375(b - 1) = 46.875
- By simplify it
∴ 2.25 b + 0.375 b - 0.375 = 46.875
∴ 2.625 b - 0.375 = 46.875
- Add 0.375 for both sides
∴ 2.625 b = 47.25
- Divide both sides by 2.625
∴ b = 18
∴ 18 rows of bricks are needed
b)
* Lets complete the missing
- The total height of the bricks in inches is equal to 2.25 times b
- The total height of the mortar is equal to 0.375 times (b - 1)
- Their sum is equal to the height of the wall or 46.875 inches
- If I write this as an equation and solve for b, then the result is
18 rows of bricks
To find the number of rows of bricks needed for a wall, we can set up an equation to solve for that number. The equation will involve the heights of the bricks and mortar layers, as well as the height of the wall. Solving the equation will give us the number of rows of bricks needed.
Explanation:To find the number of rows of bricks needed, we need to determine the total height of the bricks and the total height of the mortar. Let b be the number of rows of bricks. The total height of the bricks in inches is equal to the height of each brick multiplied by the number of rows (b). The total height of the mortar is equal to the height of the mortar layer multiplied by the number of rows minus 1 (b-1). The sum of the heights of the bricks and mortar is equal to the height of the wall, which is 4 feet minus 1/8 inches.
Writing this information as an equation, we have:
(height of the bricks x b) + (height of the mortar x (b-1)) = 4 feet - 1/8 inches
Solving this equation for b will give us the number of rows of bricks needed.

How much wrapping paper will Xan need?

Answers
Final answer:
To find the wrapping paper needed for a box with given dimensions and one largest face uncovered, calculate the total surface area, subtract the area of the largest face, resulting in 592 square cm of wrapping paper required.
Explanation:
The question concerns calculating the amount of wrapping paper required to cover a box while leaving one of the largest faces uncovered. Given the dimensions of the box are 12 cm, 10 cm, and 11 cm, we can calculate the surface area of each face and sum them up, excluding one of the largest face, which is one with dimensions 12 cm x 11 cm.
First, calculate the surface area of all the faces: 2(12cm x 10cm) + 2(12cm x 11cm) + 2(10cm x 11cm) = 240cm² + 264cm² + 220cm² = 724cm².Next, subtract the area of the largest face (which will not be covered): 12cm x 11cm = 132cm².Finally, subtract this area from the total surface area calculated: 724cm² - 132cm² = 592cm².Therefore, Xan will need 592 square cm of wrapping paper to cover the box while leaving one of the largest faces uncovered.

The sum of four consecutive integers is 342. What is the third term in the sequence
Answers
Answer:
x + x + 1 + x + 2 + x + 3 = 4x + 6 = 342
4x = 336
x = 84
The third term is 84 + 2 = 86.
To find the third term in the sequence, we need to determine the first term and the common difference. By setting up and solving equations, we find that the first term is 84 and the common difference is 1. Therefore, the third term in the sequence is 86.
Explanation:To find the third term in the sequence, we need to determine the first term and the common difference.
Let's assume the first term is 'x' and the common difference is 'd'.
The four consecutive integers can be represented as x, x + d, x + 2d, and x + 3d.
Since the sum of these four integers is 342, we have the equation:
x + (x + d) + (x + 2d) + (x + 3d) = 342
Simplifying this equation, we get:
4x + 6d = 342
Now, we have two variables and one equation, so we need another equation to solve for x and d.
We can use the fact that the integers are consecutive, so the common difference is always 1.
Plugging in the value of d = 1 in the previous equation, we get:
4x + 6(1) = 342
Simplifying further, we get:
4x + 6 = 342
4x = 336
x = 84
Therefore, the third term in the sequence is x + 2d = 84 + 2(1) = 86.
