A math question about proportions, help

The time for 22 leg-press reps is 11.9 seconds.

The lines of best fit is the trend line of the dataset.

The table is given as —

(x) : 12 32 7 26 28 15 1

(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5

To determine the equation of line of best fit, we make use of a regression calculator.

Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)

This means that x = 22.

So, we have:

y = 0.120 * 22 + 9.274

  = 2.640 + 9.274

  = 11.914

(Approximate to the nearest hundredths)

  = 11.9

Hence, the time for 22 leg-press reps is 11.9 seconds.

Hope my answer helps you.

The solution is, The triangle by 170 square inches, so, the triangle has a much larger area.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

A rectangle with sides 12 inches and 15 inches.

A triangle with a base of of 25 inches and a height of 14 inches.

so, we get,

area of rectangle is,

A = length * width

so, area = 12 * 15

area of rectangle = 180

now, we know that,

area of triangle = 1/2 * base * heigth

so, area = 1/2 * 25 * 14

area of triangle = 350

so, we get,

the triangle has a much larger area.

350-180=170

the triangle by 170 square inches

Hence, The solution is, The triangle by 170 square inches, so, the triangle has a much larger area.

Answer:

The correct graph is A.

Step-by-step explanation:

-4x/5-13/5 ≥ -9

Multiply the entire equation by 5:

-4x-13 ≥ -45

Moving the -4x:

-13 ≥ -45+4x

Moving the -45:

32 ≥ 4x or 4x ≤ 32

So:

x ≤ 8

The correct graph is A.

The answer would be graph A that describes the solution set.

Answer:

The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.

Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.

One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

Answer:

The area of a parallelogram is base x height. You multiply the base and height (represented as b and h) to get the area of the parallelogram.

In the first question, the base and height is already given to you so, 2x6=12.

12yd squared is the area for the first one.

Now lets do the second one. The base and height is also given to you so do, 6x4=24.

24m squared is the area of the second one.

Answer:

its the first one

These angles are supplementary, meaning that their sum should be 180.

Write an equation.

5x+110=180

5x+110-110=180-110

5x=70

x=14

To find the angle measure,

multiply 5 by 14.

5 x 14= 70

To check:

70+110=180

Therefore, the variable has a value of 14.

Answer:

Step-by-step explanation:

To think about this logically, lets take a different, more simplified example.

Lets say we have two numbers: 4 and 6

The product of these numbers is 24. If we doubled the product, we would get 48.

Using our original equation, how could we get a result of 48? We could double either 4, or 6. 8 times 6 equals 48, and 12 times 4 equals 48.

So, from this we can take away that in an expression, doubling one number will double the answer. On a side note, you could you use this not only when doubling a number. If you tripled a number in an expression, then the answer to the expression would also triple.

So, the answer to your question is (A) - Double one dimension

Answer:

62

Step-by-step explanation:

Answer:

The median is 62 beause it falls between the 60 and is no where near 20 or 30 70 is higher on your can find the median by looking at the lines the two ones or if the numbers are line up it would be the one one in the middle if there are two number is the middle in would be between those to numbers example 28 and 29 it would 28.5 hope this helpsStep-by-step explanation:

Answer:

[tex] \displaystyle A) -1 \frac{17}{21} [/tex]

Step-by-step explanation:

refer the attachment

the blue line refers the amount of reduction in the first day and the black line refers the amount of reduction in the second day

note that the total amount of depth of the the pool isn't specified therefore we can't assume the total depth of the pool to be 1 and as it says 'decrease' we are dealing with negative numbers

so

[tex] \rm \displaystyle \text{the level of the water in the pool decreases by $1\frac{1}{3}$ inches} \iff \boxed{- 1\frac{1}{3} }[/tex]

likewise

[tex] \rm \displaystyle \text{the level of the water in the pool decreases by $\frac{3}{8}$ inches} \iff \boxed{- \frac{3}{8} }[/tex]

since it wants the total amount of reduction we just need to add them which yields:

[tex] \displaystyle - 1 \frac{1}{3} + \bigg(- \frac{3}{8}\bigg) [/tex]

simplify complex fraction:

[tex] \displaystyle - \frac{4}{3} + \bigg(- \frac{3}{8} \bigg)[/tex]

simplify addition:

[tex] \displaystyle - \frac{41}{21} [/tex]

the option is given in complex fraction thus convert it to complex fraction:

[tex] \displaystyle -1 \frac{17}{21} [/tex]

and we're done!

hence our answer is A

Answer:

[tex]( - 1 \frac{17}{24} \: inches)[/tex]

Step-by-step explanation:

[tex]1 \frac{1}{3} + \frac{3}{8} \\ = \frac{4}{3} + \frac{3}{8} \\ = \frac{32}{24} + \frac{9}{24} \\ = \frac{41}{24} = 1\frac{17}{24} [/tex]

Answer:

16+110=126 m²

Hope it helps :)

Answer:

Area of 1 st rectangle, length = 10m and breath = 15m

So using formula , rectangle = length × breadth

= 10 m × 15 m

=150^{2}

again,

Area of 2 st rectangle, length = 6m and breath = 4m

So using formula , rectangle = length × breadth

= 6 m × 4 m

= 24m^{2}

Now ,

Final area of whole box = 1^{st} area - 2^{nd} area

= 150m^{2} - 24m^{2}

= 126 m^{2} is answer

2.  -1 + -1 + 1 = -1

3. 8x -1 = 55

4.  8x = 55 + 1

5.  8x = 56/8

6.    x = 7

Answer:

Kevin will shoot 3,000 baskets in 60 days.

Explanation:

If Kevin shoots 50 baskets per day, that means the ratio of baskets shot to number of days is 50:1.

When the 1 changes to 60, you have to divide 60/1 to see how many times 1 was multiplied to get 60, then multiply the quotient by the 50.

In this case, 60/1=60. SO, we multiply 50*60 and get 3,000.
