Pls help nobody had the question i was looking for. Divide 0.8 62 answer needs to be in decimal form. 20 points

Answer:

x = 8

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

Step 2: Add 2 to both sides.

Step 3: Divide both sides by 2.

Step 4: Check if solution is correct.

Therefore, x = 8.

Answer:

x=8

Step-by-step explanation:

7x-2=5x+14

collect like terms (remember when taking a value across the equality sign name sure the sign of the value changes)

7x-5x=14+2

2x=16

divides both sides by the value of x

x=16/2

x=8

Answer:

A = 197 tons

B = 84 tons

Step-by-step explanation:

Given Equations: A + B = 281     A - B = 113

A = 113 + B

113 + B + B = 281

2B = 281 - 113

2B = 168

B = 84

A = 113 + 84

A = 197

Step-by-step explanation:

Well I can't really draw the square, but.
If the the squares perimeter is 20, and all sides on a square are the same, and there are 4 sides.
Do 20/4 which = 5 inches.
Then area is length x width,
So 5x5 which equals 25 inches.

Step-by-step explanation:

Each grid is divided into units by the dark vertical lines, and into fractions of the last unit by the lighter vertical lines. The left-side figure, for example, shows 3 units, the last of which is divided into fourths (1/4s).

The lighter horizontal lines divide the vertical space into fractions. The left side figure has horizontal lines dividing the vertical space into tenths (1/10s).

Overall, each grid represents multiplication of a mixed number by a fraction.

__

The left-side figure has coloring horizontally covering two full units and 3/4 of the last unit. The coloring vertically occupies 3 of the 10 spaces, Overall, the figure represents multiplication of 2 3/4 by 3/10. That matches the solution required for the question about July rainfall (bottom word problem).

__

The top right figure has coloring horizontally that covers two full units and 2/3 of the last unit. The coloring vertically occupies 2 of the 3 spaces. Overall, the figure represents multiplication of 2 2/3 by 2/3. That matches the solution required for the question about mat area (top word problem).

__

The bottom right figure has coloring horizontally that covers three full units and 1/5 of the last unit. The coloring vertically occupies 1 of the 4 spaces. Overall, the figure represents multiplication of 3 1/5 by 1/4. That matches the solution required for the question about the weight of carrots (middle word problem).

_____

Additional comment

Perhaps the confusing part is that the answer to the question, as represented by the shaded area, is not easy to determine from the figure.

The left-side figure, for example, has a blue shaded area that totals 6/10, and an orange shaded area that totals 9/40. The answer to the question posed is then 6/10 +9/40. The diagram offers no help in figuring the value of that sum, hence the answer to the question.

The numbers of large bowl sold at the fair is 20

Data;

To solve this problem, we need to write system of equations for this.

Let x represent the numbers of small ceramic bowl

let y represent the numbers of large ceramic bowl

[tex]x+y=32...eq (i)\\18x + 35y = 916 ...eq(ii)[/tex]

From equation (i), let's make x the subject of formula

[tex]x + y = 32\\x = 32 - y...eq(iii)[/tex]

Let's substitute equation (iii) into equation (ii)

[tex]18x+35y = 916\\x = 32 - y\\18(32 -y) + 35y = 916\\576- 18y + 35y = 916\\17y = 916 - 576\\17y = 340\\\frac{17y}{17} = \frac{340}{17}\\ y = 20[/tex]

Answer:

x² + (y - 2)² = 41

Step-by-step explanation:

the equation of a circle in standard form is

(x - h )² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

The distance from the centre to a point on the circle is the radius r

calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (5, - 2 )

r = [tex]\sqrt{(5-0)^2+(-2-2)^2}[/tex]

  = [tex]\sqrt{5^2+(-4)^2}[/tex]

  = [tex]\sqrt{25+16}[/tex]

  = [tex]\sqrt{41}[/tex] , then r² = ([tex]\sqrt{41}[/tex] )² = 41

then

(x - 0)² + (y - 2)² = 41 , that is

x² + (y - 2)² = 41 ← equation of circle

Answer:

10.) y = [tex]\frac{-1}{4}[/tex]x + [tex]\frac{17}{4}[/tex]  11.) y = 3x + 7

Step-by-step explanation:

10.) when given, slope, and a point you can use the equation y=mx+b to solve for "b" as your unknown. so, you substitute everything that you do know y = 4. x = 1. m = -1/4.

y=mx+b becomes 4 = [tex]\frac{-1}{4}[/tex](1) + b

4 = -1/4 +b

add the 1/4th to both sides to isolate b.

you end up with an answer of, 4[tex]\frac{1}{4}[/tex] which equals [tex]\frac{17}{4}[/tex]

so you end up with b =  [tex]\frac{17}{4}[/tex]

-------------------------------------------------------------------------------

11.) Do the same thing with the other problem.

you know m = 3. x = -1 and y = -4

substitute what you know now.

y = mx+b becomes -4 = 3(-1) + b

add -3 to both sides to isolate b

then you end up with an answer of

b = 7

The required confidence interval for the population mean is; B: CI = (66.58%, 71.35%)

We are given;

Sample size; n = 1450

Sample number; x = 1000

Thus,sample proportion is;

p^ = x/n = 1000/1450

p^ = 0.69

We are not given the population proportion but we will assume; p = 0.5

Formula for confidence interval is;

CI = p^ ± z√(p(1 - p)/n)

Where z for CL of 95% is; z = 1.96

Thus;

CI = 0.69 ± 1.96√(0.5(1 - 0.5)/1450)

CI = 0.69 ± 0.026

CI = (66.58%, 71.35%)

Answer:

100%

Step-by-step explanation:

Assume the fraction is X/Y.

Increase the numerator by 60%:  1.6X

Decrease the denominator by 20%:  0.8Y

New value:  1.6X/0.8Y

That is equal to 2(X/Y)

The fraction increases by 100%  [X/Y to s(X/Y)]

Answer:

The radius is approx. 7.5

Let me know if it helps or if I got anything wrong!

Step-by-step explanation:

To find the circumference, you need to multiply the diameter by pi (3.14)

And for vice versa, just divide.

Since we don't know the diameter nor radius, we need to divide the Circumference (C) by pi (3.14)

47/3.14=14.968

Which is rounded up to 15.

We have now found the diameter.

We also know that the radius is half of the diameter

Step-by-step explanation:

One side;

7 x 8 = 56, the side parallel to it is also 56 as well, so 56(2).

Second(bottom) side;

8 x 4 = 32, the side parallel to it(the side above) is also 32 as well, so 32(2).

Third(front) side;

4 x 7 = 28, the side parallel to it(backside) is also 28 as well, so 28(2).

You add all those products to get the surface area:

Answer:

x = 29

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

3(x + 2) + 52 + 35 = 180 , that is

3(x + 2) + 87 = 180 ( subtract 87 from both sides )

3(x + 2) = 93 ( divide both sides by 3 )

x + 2 = 31 ( subtract 2 from both sides )

x = 29
