Find a
a. 4
b. 6
c. 9

I believe it’s 8 because 24 divided 75% is 32.

To find the total number of fish in a tank where 75% are goldfish and there are 24 goldfish, solve the equation 0.75 × Total Number of Fish = 24, resulting in 32 fish in total.

The question asks about calculating the total number of fish in a tank knowing that 75% of them are goldfish, and there are 24 goldfish. To find the total number of fish in the tank, we set up a proportion based on the given information that 75% (or 0.75 when converted to a decimal) of the total number of fish equals 24 goldfish.

Mathematical equation: 0.75 × Total Number of Fish = 24.

To solve for the Total Number of Fish, we divide both sides of the equation by 0.75:

Total Number of Fish = 24 ÷ 0.75

Total Number of Fish = 32

Therefore, there are 32 fish in the tank in total.

Answer:

Strongly Disagree: 24°

Somewhat Disagree: 16°

Neither Agree nor Disagree: 100°

Somewhat Agree: 350/900 = 140°

Strongly Agree: 200/900 = 80°

Step-by-step explanation:

To find the degrees on a pie chart we need to find the proportion of each category over the total.

The total is: 60 + 40 + 250 + 350 + 200 = 900

The proportions of each category is going to be:

Strongly Disagree: 60/900 = 1/15.

Somewhat Disagree: 40/900 = 2/45.

Neither Agree nor Disagree: 250/900 = 5/18.

Somewhat Agree: 350/900 = 7/18.

Strongly Agree: 200/900 = 8/9.

We find the degrees by multiplying the proportions to 360 degrees as follows:

Strongly Disagree: 24°

Somewhat Disagree: 16°

Neither Agree nor Disagree: 100°

Somewhat Agree: 350/900 = 140°

Strongly Agree: 200/900 = 80°

The total should be 360°. Let's prove it:

24 + 16 + 100 + 140 + 80 = 360°.'

Area of rectangle

A = L * W

W = A/L

W = 80 / 8

W = 10

Answer

10 feet

The Area of the rectangle is the product of length and width. The width of the rectangle is 10 ft.

For a rectangle with length and width L and W units, we get:

Area of the rectangle = (L × W) unit^2

Perimeter of the rectangle = 2(L + W) units

Given the area of the rectangle is 80 ft², while the length of the rectangle is 8 feet. Therefore, the width of the rectangle will be,

Area of the rectangle = Length × width

80 ft² = 8 ft × width

width = 10 ft

Hence, the width of the rectangle is 10 ft.

X axis is the answer to you question because it’s going across not up nor down

The answer is A. The x-axis

Answer:

x = 4

Step-by-step explanation:

When a tangent and a secant are drawn from an external point to a circle.

Then the product of the external part of the secant and the entire secant and the square of the measure of the tangent are equal, hence

x(x + 5) = 6²

x² + 5x = 36 ( subtract 36 from both sides )

x² + 5x - 36 = 0 ← in standard form

(x + 9)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

However, x > 0 ⇒ x = 4

Answer:

20 4/5

Step-by-step explanation

13/5 x 8/1 = 104/5= 20 4/5

The product of [tex]\(1 \frac{3}{5}\)[/tex] and [tex]\(8\)[/tex] is calculated by first converting the mixed number to an improper fraction and then multiplying the two fractions together.

Step 1: Convert [tex]\(1 \frac{3}{5}\)[/tex] to an improper fraction.

To convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fractional part and add the numerator of the fractional part. Then, place the result over the original denominator.

For [tex]\(1 \frac{3}{5}\)[/tex] , the whole number is [tex]\(1\)[/tex], and the fractional part is [tex]\(\frac{3}{5}\)[/tex]. So, we have:

[tex]\[ 1 \times 5 + 3 = 5 + 3 = 8 \][/tex]

Thus, [tex]\(1 \frac{3}{5}\)[/tex]  as an improper fraction is [tex]\(\frac{8}{5}\)[/tex].

Step 2: Multiply the improper fraction by \(8\).

Now, we multiply [tex]\(\frac{8}{5}\)[/tex] by [tex]\(8\)[/tex] . When multiplying fractions, we multiply the numerators together and the denominators together:

[tex]\[ \frac{8}{5} \times 8 = \frac{8 \times 8}{5} \][/tex]

Step 3: Simplify the product.

[tex]\[ \frac{8 \times 8}{5} = \frac{64}{5} \][/tex]

So, the product of [tex]\(1 \frac{3}{5}\)[/tex]  and [tex]\(8\)[/tex] is [tex]\(\frac{64}{5}\)[/tex].

To express this as a mixed number, we divide [tex]\(64\)[/tex] by [tex]\(5\):[/tex]

[tex]\[ 64 \div 5 = 12 \text{ remainder } 4 \][/tex]

Thus, [tex]\(\frac{64}{5}\)[/tex]  as a mixed number is [tex]\(12 \frac{4}{5}\)[/tex].

The final answer is[tex]\(12 \frac{4}{5}\) or \(\frac{64}{5}\).[/tex]

The answer is $55

You multiply 10 by 75 which gives you $750 and subtract the borrowed money by $750 to get $55

Final answer:

Andrew will pay a total of $55 in interest on the $695 loan when he makes 10 monthly payments of $75 each.

Explanation:

The student is asking how much interest Andrew will pay on a $695 loan if he makes 10 monthly payments of $75 each. To find the total interest paid, we need to calculate the total amount Andrew will pay back and then subtract the original loan amount from it.

Total amount paid by Andrew = 10 monthly payments times $75/payment = $750

Original loan amount = $695

Interest paid = Total amount paid - Original loan amount = $750 - $695 = $55

Therefore, Andrew will pay $55 in interest to repay the loan for the new TV.

Answer:

x=1, -3

Step-by-step explanation:

Answer:

The first step would be to add 3 on both sides of the equation.

Step-by-step explanation:

Given a polynomial or a quadratic equation, the first step in completing the square is to take the constant term to the other side of the equation. In the polynomial given the constant term is -3 which implies that we can add 3 on both sides of the equation in order to eliminate this constant term from the left hand side;

x^2 -x -3 +3 = 0 + 3

x^2 - x = 3

Answer:

The first step of Bao yu is to isolate the constant

Step-by-step explanation:

For using completing the square to solve the polynomial equation, the equation should be of the type [tex]a^2 \pm 2ab +b^2[/tex] that can also be written as:[tex](a\pm b)^2[/tex]

so, for the given equation: [tex]x^2 -x -3 =0[/tex]

The first step should be to isolate the constant:

[tex]x^2 -x = 3[/tex]

Then we have to make the middle term according to 2ab where a = 1x and b= (1/2) i.e, -2(1x)(1/2) = 1x

so,by adding (1/2)^2 on both sides of equation, we can complete the formula:

[tex]x^2 -x = 3[/tex]

[tex]x^2 -2(x)(\frac{1}{2}) + (\frac{1}{2})^2 = 3 (\frac{1}{2})^2[/tex]

Solving we get,

[tex](x- (\frac{1}{2}))^2 = 13/4[/tex]

So, the first step is to isolate the constant.

The solution of the equation is 15

Step-by-step explanation:

* Lets explain how to solve the problem

- The equation is 3(2x + 5) = 3x + 4x

- The solution of the equation is the value of x

Lets find the value of x

- The left hand side is 3(2x + 5) lets simplify it

- Multiply the two terms of the bracket by 3

∵ 3(2x+ 5) = 3 × 2x + 3 × 5

∴ 3(2x + 5) = 6x + 15

- The right hand side is 3x + 4x

∵ They are like terms, then we will add them

∴ 3x + 4x = 7x

- Now equate the left hand side and the right hand side

∴ 6x + 15 = 7x

- Subtract 6x from the two sides

∴ 15 = 7x - 6x

∴ x = 15

∵ x is the solution of the equation

∴ The solution of the equation is 15

Answer:

The measure of  angle x is 90°

Step-by-step explanation:

Given the figure in which

∠1=88°, ∠6=89°

we have to find the value of x.

∠5=∠6=89°   (∵ Vertically opposite angles)

∠1+∠4=∠6  ( ∵ By exterior angle property)

88°+∠4=89°

∠4=89°-88°=1°

As AC=CB (both are radii of same circle)

∴ ∠4=∠3=1°

Now, by exterior angle property

x=∠5+∠3=89°+1°=90°

Hence, the measure of  angle x is 90°

Applying the angle of intersecting chords theorem, the value of x in the diagram showing the circle is: C. 90.

According to the angle of intersecting chords theorem, the measure of the angle formed at the point of intersection of two chords inside a circle equals half the sum of the intercepted arcs.

89 = 1/2(88 + x) [based on the angle of intersecting chords theorem]

2(89) = 88 + x

178 = 88 + x

178 - 88 = x

x = 90° (Option C).

Answer:

5/9

Step-by-step explanation:

To have an even number (let's call it E) OR a number greater than 9 (let's call it N), you can have EITHER of them.

So, to calculate the probability, you need to find the probability of having E and then the probability of having N... then ADD them together.

To calculate the probability, just look on the image.

Probability of having an even number: 18 (red circles)

Probability of having a number greater than 9 (that is NOT already counted in the even scenario): 2 (within the blue zone, but not red)

We don't count a same possibility (like 6,4) twice, only once.

Total: 18 + 2 = 20

Out of 36 possibilities

So, probability is 20/36, or 10/18 or 5/9.

Answer:

(- 3, 6)

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y) → (- x, y), hence

(3, 6) → (- 3, 6)

The image of the point (3, 6) reflected across the y-axis is (-3, 6) since only the x-coordinate changes sign.

Reflection of a point across the y-axis in a Cartesian coordinate system involves changing the sign of the x-coordinate of the point while keeping the y-coordinate the same. For point (3, 6), when it is reflected across the y-axis, the x-coordinate becomes the opposite sign, while the y-coordinate remains unchanged. Therefore, the image of the point (3, 6) after reflection across the y-axis is at (-3, 6). This transformation elucidates the geometric effect of y-axis reflection, showcasing how points are mirrored across the axis while maintaining their vertical position, essential in geometry, graphics, and spatial reasoning for analyzing symmetrical patterns and transformations.

The linear velocity at the end of the blade is 13571.7 inches per minute by using the circumference of the circle that the blade makes to calculate the linear velocity at the end of the blade.

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Here, The total distance in 1 minute is 60 times circumference of the circle made by the end of the blade of the lawnmower.

Since, The blade is 36 inches long, it can be taken as radius of that circle.

The circumference is thus calculated as;

⇒ linear velocity = 226.19 × 60

                           = 13571.7 inches per minute

Thus, The linear velocity at the end of the blade is 13571.7 inches per minute.
