... what is the value of x , ...
... x + 7 = 11 .. ​

The area of the triangle is x + 1 cm², while the area of the rectangle is x cm². Therefore, there is no value of x that makes the areas of both figure equal, because there is no solution to the equation.

A triangle's area = 1/2(base)(height)

A rectangle's area = length × width.

Area of the green triangle = 1/2(x + 1)(2)

Area of the green triangle = x + 1 cm²

Area of the rectangle = x × 1

Area of the rectangle = x cm²

Setting both areas equal, we have:

x + 1 = x

x - x = -1

0 = -1 [not true]

There's no solution or the values of x.

Therefore, we can conclude that there are no values of x for which the areas of both shapes are equal, because there is no solution to the equation.

Answer:

2 lengths and 3 widths

444 = 2*L + 3*w --> L = (444 - 3w)/2 = 222 - (3/2)w

Area = length x width

Area (w) == (222 - (3/2)w ) w

The max occurs at the average of the zeros.

The zeros are 222 - (3/2)w = 0 or w=0

222 = (3/2)w or w=0

w = 444/3=148 or w=0

The average is (444/3 +0)/2 = 222/3=74

width is 74 and length is 222 - (3/2)(74) = 222 - 111 = 111

The max area is 74 * 111 = 8214

Answer:

Step-by-step explanation:

To find this, we must set up a proportionality formula.

6                   8

-        =          -

40                 x

Our goal is to find x.

First we cross multiply and get:

6x=320

Now we can divide each side by 6 to get x by itself.

x=53.33,

however, because you cannot have less than a whole orange in a box, each box contained 53.

When Z=6 and Y=64 the given proportionality value of x = 1/2.

What is proportionality?

  The concept of proportionality in mathematics denotes the linear relationship between two quantities or variables. The size of one item increases by twofold, whereas the size of the other quantity decreases by one-tenth of the earlier amount. Two integers that each represent a component of a whole are compared to determine their proportion. In essence, a percentage declares that two fractions are the same even if the amounts are different. For instance, half of 10 marbles is equal to half of 50 marbles in terms of proportion.

Here Z varies jointly as the square root of the product of X and Y.

Then,

=> Z∝[tex]\sqrt{XY}[/tex]

=>Z=k[tex]\sqrt{XY}[/tex]

Where k is constant . Now put X=3 , Y = 12, Z=3.

=> 3=k*[tex]\sqrt{12*3}[/tex]

=> k = 6/3 = 2 .

Then the equation is ,

=> Z==3[tex]\sqrt{XY}[/tex]

Now put Z=6 and Y=64

=> 6 = 3[tex]\sqrt{x*64}[/tex]

=> 2/8 =[tex]\sqrt{x}[/tex]

=>[tex]\sqrt{x}[/tex] = 1/4

=> x = 1/2.

Hence the value of x is 1/2.

The line is:

y = 400*x + 2000

And the statements are:

The original purchase price of the computer is given by the y-intercept, which is $2,000

The change in the price of the computer is the slope, which is 400.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

slope = (y2 - y1)/(x2 - x1)

Using the graph we can identify two points like:

(1, 1600) and (5, 0)

Then the slope is:

a = (0 - 1,600)/(5 - 1) = 400

Answer:

mAngle5 = 52° by

Alternate Interior angles

Step-by-step explanation:

When you have a pair of parallel lines and a transversal (the line that crosses them both)

this set up makes 8 angles....ALL the angles are either the same measure or they add up to 180°. Literally, if you know the measure of ONE angle, you can find the measure of all 8 angles. Its only two different numbers for all 8.

So, for your problem the two angles are in between the parallel lines (interior) and on different sides of the tranversal (alternate). By the Alternate Interior Angle Theorem they are congruent. One of them is 52° so the other one is also 52°

The rectangle has its width to be 8 cm

From the question, we have the following parameters that can be used in our computation:

The length of a rectangle is four more than twice its width

The perimeter of the rectangle is 56 cm.

The above parameters imply that

L = 2W + 4

P = 2(L + W)

Where L represents the Length and W represents the width

The perimeter is given as 56

So, we have

2(L + W) = 56

So, we have

L + W = 28

Substitute L = 2W + 4 in L + W = 28

2W + 4 + W = 28

Evaluate

3W = 24

Divide by 3

W = 8

Answer:

82

Step-by-step explanation:

1.) Recognize that this is the Pythagorean Triple 9, 40, 41, just multiplied by two (9*2 = 18, 40*2 = 80).

2.) Now, to find the third number, we just multiply 41 by 2 to get 82.

Answer:

The hypotenuse is equal to 82 centimeters.

Step-by-step explanation:

Using the Pythagorean theorem (a^2 + b^2 = c^2), which states that the legs of a right triangle (a and b) squared, equal the hypotenuse squared, we can plug in the values of the legs of the right triangle into spots a and b.  This gets us the equation 80^2 + 18^2 = c^2. We can then square the values to get 6400 + 324 = c^2. We then get 6724 = c^2, and then take the square root of both sides to get the value of c, the hypotenuse. This gets us c = 82, so the hypotenuse is equal to 82 centimeters.

The linear function y = -12x + 360, representing Amir's height at a time of x minutes, is graphed at the end of the answer.

The slope-intercept representation of a linear function is given by the rule shown as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

From the test, his rate is of -12 m/s, hence the slope of the function is given as follows:

m = -12.

When x = 30, y = 0, hence the intercept b of the linear function can be obtained as follows:

0 = -12(30) + b

b = 30 x 12

b = 360.

Thus the equation is:

y = -12x + 360.

Step-by-step explanation:

The amount of time spent on bicycle by Jim =6.5 hours

The amount of time spent on walking by Jim =2.5 hours

To calculate speed, divide the distance travelled by the time it took to complete the voyage, so speed = distance divided by time. These equations can be reduced as s=d/t, where s represents speed, d represents distance, and t represents time.

Distance divided by time equals speed. Distance = time * speed

To solve for speed or rate, utilize the speed formula, s = d/t, which implies speed equals distance divided by time. To solve for time, utilize the time formula, t = d/s, which implies time equals distance divided by speed.

Given,

Distance=270miles

Time=9 hours

Speed by walk=4 miles/hour

Speed by cycle=40 miles/ hour

t= time for riding a bicycle

9-t= time for walking

Distance= Speed ×Time

270=40t+4(9-t)

40t+36-4t=270

36t=234

t=6.5

Time spent on bicycle = 6.5 hours

Time spent on walking = 9-6.5

The slope-point equation of a line is given as:

y-y1 = m(x−x1)

where m is the slope of the line, and slope (m) = y2−y1 / x2−x1

Given: the points (-3, -13) and (11, 9)

x1 = -3, y1 = -13 and x2 = 11, y2 = 9

slope(m) = 9-(-13) / 11-(-3) = 22/14 = 11/7

Using y-y1 = m(x−x1), put m = 11/7 and make y the subject:

y-y1 = m(x−x1)

y-(-13) = 11/7(x-(-3))

y + 13 = 11/7(x+3)

y + 13 = 11/7(x) + 33/7

y = 11/7(x) + 33/7 - 13
