308 cubic yards of sand will be needed for 280 square yards of surface.

If 1.1 cubic yards of sand are needed for every 100 square yards of surface, we can find the amount of sand needed for 280 square yards of surface using the proportion:

1.1 cu yd / 100 sq yd = x cu yd / 280 sq yd

To find the value of x, we can cross-multiply and solve for x:

1.1 cu yd * 280 sq yd = x cu yd * 100 sq yd

x = 1.1 cu yd * 280 sq yd / 100 sq yd

x = 308 cu yd

So, 308 cubic yards of sand will be needed for 280 square yards of surface.

Step-by-step explanation:

Answer:

96

Step-by-step explanation:

The following equations are equivalent:

2 + x = 5

x + 1 = 4

Negative 5 + x = negative 2

This is because, in each equation, x is the same variable, and it has the same value on both sides of the equation.

In the first equation, x is equal to 3.

In the second equation, x is equal to 3

In the third equation, x is equal to -3

Note that the equation 9 + x = 6 and x + (negative 4) = 7 are not equivalent as these equations have different values for x.

540 yards should be purchased to enclose the deck and option B is correct.

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides.

A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.

Pools dimension = 1:3

Length = 60 × 3

= 180

Breadth= 30 × 4

= 90

Perimeter of rectangle = 2(l+b) = 2(90+180)

Step-by-step explanation:

Y-intercept linear 12 shows that the total cost will be $12.00 when the taxi travels 0 miles.

the connection between two variables that, when plotted on the coordinate plane, forms a straight line. The term "linear expression" refers to both the linear equation and the expression that depicts a linear relationship.

(2, 15), (5, 19.50), (7, 22.50), and (10, 27) are the coordinates (15, 34.50)

We will obtain a straight line if we plot the points on the XY coordinate system. The line crosses the Y axis at 12.00, as can be seen. As a result, the y-intercept is 12.00, and its coordinate is (0,12)

The y-intercept in this case is 12, which indicates that the total cost will be $12.00 even if the taxi travels 0 miles.

The solution for the given decimal multiplication is 0.025.

To multiply two decimal numbers, first multiply the values without the decimal points.

The digits in the factors that follow the decimal point should now be added together.

Following that, the dot should be placed in the product so that it has the same number of digits as the total number of factors.

If there are more decimal places than digits in the number, place zeroes immediately after the dot.

If there are more decimal places present compared to digits in the product, fill the decimal places with zeroes immediately after the dot.

For the given question, multiply -5 * -5 = 25

Now the total digits after the decimal point in factors are 3.

The equation of line segment AB, whose endpoints are A(x, y) = (2, 1) and B(x, y) = (1, - 1.5), is P(x, y) = (1 - k) · (2, 1) + k · (1, - 1.5), for 0 ≤ k ≤ 1.

In this problem we need to determine the equation that described the line segment AB, whose endpoints are points within other two line segments. The location of a point can be found by means of the following formula:

P''(x, y) = P(x, y) + k · [P'(x, y) - P(x, y)], 0 ≤ k ≤ 1

Where:

First, determine the locations of endpoints A and B:

A(x, y) = (- 2, 3) + 0.5 · [(6, - 1) - (- 2, 3)]

A(x, y) = (- 2, 3) + 0.5 · (8, - 4)

A(x, y) = (- 2, 3) + (4, - 2)

A(x, y) = (2, 1)

B(x, y) = (4, 3) + 0.75 · [(0, - 3) - (4, 3)]

B(x, y) = (4, 3) + 0.75 · (- 4, - 6)

B(x, y) = (4, 3) + (- 3, - 4.5)

B(x, y) = (1, - 1.5)

Second, derive the equation of line segment AB:

P(x, y) = A(x, y) + k · [B(x, y) - A(x, y)]

P(x, y) = (2, 1) + k · [(1, - 1.5) - (2, 1)]

Answer:

m∠B = 83°

EF = 10

Step-by-step explanation:

Two triangles are similar if their corresponding angles are the same size.

Therefore if ΔABC ~ ΔDEF then:

Interior angles of a triangle sum to 180°:

⇒ m∠A + m∠B + m∠C = 180°

⇒ 24° + m∠B + 73° = 180°

⇒ m∠B + 97° = 180°

⇒ m∠B = 83°

In similar triangles, corresponding sides are always in the same ratio.

Therefore if ΔABC ~ ΔDEF then:

⇒ AB : DE = BC : EF = CA : FD

⇒ 12 : DE = 8 : EF = 16 : 20

Therefore, to find the length of EF:

[tex]\implies \sf 8 : EF = 16 : 20[/tex]

[tex]\implies \sf \dfrac{8}{EF} = \dfrac{16}{20}[/tex]

[tex]\implies \sf 8 \cdot 20= 16 \cdot EF[/tex]

[tex]\implies \sf160= 16 \cdot EF[/tex]

[tex]\implies \sf EF=\dfrac{160}{16}[/tex]

y = (-4/11)x + 5.27 is the equation that passes through each pair of points (9,2) (-2,6).

A group of numbers and variables without an equal sign are known as a numerical expression. A set of numbers and variables with an equal sign is referred to as an equation.

Once you are familiar with these terms, you will realise that an equation is just two expressions joined by an equal sign. You can also write expressions, equations, and simplify equations.

To find an equation of the line that passes through each pair of points (9,2) (-2,6) we need to find slope and convert it to y-intercept form

Slope formula = y - y₁ = m(x - x₁)

Putting the values in the formula we get

2 - 6 = m(9 - (-2))

-4 = m(11)

m = -4/11

As we have found slope, we can find the slope intercept form i.e.

y - 2 = -4/11(x -9)

y = (-4/11)x + 3.27 + 2

y =  (-4/11)x + 5.27

Thus, y = (-4/11)x + 5.27 is the equation that passes through each pair of points (9,2) (-2,6)

Perimeter is a measure of the distance around the outside of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape. The formula for perimeter depends on the shape.

Answer: The interest rate is 0.16 or 16% ✅

Step-by-step explanation:

The interest rate is the percentage of the principal (the initial amount of money) that is paid as interest over a certain period of time. To find the interest rate in this scenario, we can use the formula:

Interest = Principal x Interest Rate x Time

In this case:

Interest = $12,800

Principal = $40,000

Time = 4 years

So we can set up the equation:

12800 = 40000 x Interest Rate x 4

To find the interest rate, we can divide both sides of the equation by 40000 x 4, which gives us:

12800 / (40000 x 4) = Interest Rate

We can simplify this fraction:

0.16 = Interest Rate

So the interest rate is 0.16 or 16%.

When Todd made $12,800 in interest by placing $40,000 in a savings account with simple interest for 4 years, the interest rate was 7.5%.

Simple interest is a formula for calculating the amount of interest that will be charged on a sum of money at a specific rate and during a specific time frame.

In contrast to compound interest, where the interest of one year's principal is added to the principal of the following year to calculate the interest, the principal sum in the case of simple interest stays the same.

Simple Interest = [tex]$ \frac{ \text P \times \text R \times \text T}{100}[/tex]

where,

P = Principal,

R = Rate of Interest in % per annum, and

T = Time, in years

Here given that,

Todd made $12,800 in interest, i.e. Simple Interest = 12,800

By placing $40,000 in a savings account, i.e. Principal = 40,000

with simple interest for 4 years, i.e. Time = 4 years

To find, interest rate

Substitute the data into the simple interest formula

[tex]$ \Rightarrow 12,800 = \frac{40,000 \times \text R \times 4}{100}[/tex]

[tex]$ \Rightarrow \text R = \frac{ 12,000 \times 100}{40,000 \times 4}[/tex]

[tex]$ \Rightarrow \text R = \frac{1,200,000}{160,000}[/tex]

⇒ R = 7.5%

Thus, the interest rate was 7.5%.

The annual interest rate that yields $31 from $600 in 10 months is 6.2%

An interest is the amount earned by placing a sum of money in a savings account or in an investment.

The principal amount you put in the account, P = $600

The amount (interest) earned in 6 months, I = $31

The duration over which the interest of $31 is earned, T = 10 months

The annual interest rate is found as follows;

The annual interest rate is the interest rate per year

The number of months in a year = 12 months

The formula for the simple interest, I, is presented as follows;

I = P·R·T

Where;

I = The simple interest earned

P = The principal amount saved in the account

R = The annual interest rate

T = The time duration the amount was saved in years

12 months = 1 year

Therefore; 10 months = (1/12) × 10 year = (5/6) year

The time, T, of 10 months = (5/6) year

31 = 600 × R × (5/6)

R = 31/(600 × (5/6)) = 0.062

0.062 in percentage is 0.062 × 100 = 6.2%
