Answer:

Volume of pyramid with square base is 1057.54 m³

Step-by-step explanation:

We are given:

Length of base of pyramid = 14.4 m

Height of pyramid = 15.3 m

We need to find:

Volume of pyramid with square base

The formula used is: [tex]Volume=\frac{1}{3}\times a^2 \times h[/tex]

Where a = base of pyramid and h is height

Putting values and finding volume

[tex]Volume=\frac{1}{3}\times a^2 \times h\\Volume=\frac{1}{3}\times (14.4)^2 \times (15.3)\\Volume=\frac{1}{3}\times 207.36 \times 15.3\\Volume=1057.54 \ m^3[/tex]

So, Volume of pyramid with square base is 1057.54 m³

Answer: 2.899494936610

Step-by-step explanation:

-6x-2y=42

x-y=-15

Multiply x-y=-15 by 6 ( eliminate the x first)

6(x-y)=6(-15)

(6)(x)=6x

(6)(-y)=-6y

6(-15)=-90

-6x-2y=42

6x-6y=-90

eliminate x the systems of equations by subtracting

-6x+6x-2y+-6y=42-90

-2y-6y=42-90

-8y=-48

divide both sides by -8 to get y by itself

-8y/-8=-48/8

y=6

Find x by substitution method

use y=6 into one of the system of equations

x-y=-15

x-6=-15

move -6 to the other side

sign changes from -6 to +6

x-6+6=-15+6

x=-15+6

Answer:

y=-2x+5; slope is -2

Step-by-step explanation:

slope is rise/run. we can see it rises 2 and goes left one which would give us rise/run=2/-1=-2. that is our slope.

using y=mx+b to write the equation, m is slope and b is the y-int.. we can see that the y-int. is (0,5). we can plug 5 into b.

plugging b and m in we can get the equation: y=-2x+5

Answer:

the last option of 135°.

Step-by-step explanation:

The total degree of the rectangle is 360°. But it was sliced, so with the remaining measurements, subtract each of them from 360°.

90°+90°+45°+x°=360°

225°+x°=360°                 add all of the values on the left side, then subtract 225 on both sides to solve for the value of x°.

x°=135°

Answer:

2.8

Step-by-step explanation:

From the similarity ratio we can calculate the missing side length for the smaller rectangle

and when we add all side lengths the answer is 2.8

For every hour he works over 40 hours, he is paid an additional $7.50.

Ray’s error when he miscalculated his overtime pay is +$45.

Suppose the actual value and the estimated values after the measurement are obtained. Then we have:

Error = Actual value - Estimated value

His normal pay is $15/h

150%/100 = 1.5

Multiply his normal pay by the rate in decimal form;

$15 X 1.5 = $22.5

His OT pay is $22.5/h.

Additional money = (OT pay) - (Normal pay)

= $22.5 - $15

= $7.5

Or $7.5 = $7.50

Thus, For every hour he works over 40 hours, he is paid an additional $7.50.

Ray actual pay for the week was $100 then from the question he incorrectly calculated it as {$100 + $45} = $145 which is $45 above his actual pay.

Error = measured value - actual value.

Error = $145 -$100 =$45.

Since the value $145 is greater than his actual pay $100, we have to include a positive sign to the error $45.

Therefore, Error = +$45.

Answer: m∠T = 48°

ΔMAT has MA = MT

=> ΔMAT is a isosceles triangle at M

=> ∠A = ∠T = (180° - ∠M)/2

=> x + 20  = (180 - 3x)/2

⇔ 2x + 40 = 180 - 3x

⇔ 5x = 140

⇔ x = 140/5

⇔ x = 28

=> ∠A = ∠T = 28 + 20 = 48°

Answer:

Percent increase from 2000 to 2001 is 12% and from 2001 to 2002 is 12.6%. Thus period of 2001 to 2002 has higher increase percentage.

Solution:

Given that,

Total circulation of local newspaper in 2000 = 3250

Total circulation of local newspaper in 2001 = 3640

Total circulation of local newspaper in 2002 = 4100

Finding percent of increase in the newspaper’s circulation from 2000 to 2001:

Finding percent of increase in the newspaper’s circulation from 2001 to 2002:

As we can see 12% < 12.6%

So period of 2001 to 2002 has higher increase

The distance between the point JM will be 4.81 units.

In science and math, the centroid of a planar figure or firm figure, also known as the point of intersection or center of the figure, is the mean absolute position of all of the other points on the subject's surface.

The centroid of the triangle is given as,

(x, y) = [(x₁ + x₂ + x₃) / 3, (y₁ + y₂ + y₃) / 3]

Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL. Then the centroid for △JKL is at point M is given as,

(x, y) = [(7 + 1 + 5) / 3, (8 + 2 + 2) / 3]

(x, y) = (13/3, 12/3)

(x, y) = (13/3, 4)

Then the distance between the point JM is calculated as,

D² = (13/3 - 7)² + (4 - 8)²

D² = 7.1111 + 16

D² = 23.11

D = √23.11

D = 4.81 units

The distance between the point JM will be 4.81 units.

take the (1/2) and distribute it to the 6x and the 2

(3x-1) - 3(x-1)

next, distribute the 3 to the x and the 1
