thats what I see im so sorry if im wrong

Answer:

someone pls correct me if im wrong but your supposed to do L x W x H

Step-by-step explanation:

so you would do 5x6x8

not sure if that is right or not that what we did in class hope that helps =)

Answer:240

Step-by-step explanation:

5*6*8=240

Step-by-step explanation:

try the option shown in the attachment.

Finally,

[tex]A(-2-\sqrt{3};0);[/tex]

[tex]B(-1-\sqrt{7};3-2\sqrt{7});[/tex]

[tex]C(-2+\sqrt{3};0);[/tex]

[tex]D(-1+\sqrt{7};3+2\sqrt{7});[/tex]

[tex]E(0;5);[/tex]

[tex]F(-\frac{5}{2};0);[/tex]

[tex]G(-2;-5).[/tex]

in order to calculate the points E & F it is needed to solve the equations y=2*0+5 and 2x+5=0;

in order to calculate the vertex G it is needed to find x-coordinate:

x=(-4)/(2*1)=-2 and to substitute x=-2 into y=x²+4x-1 (y=-5).

Angle 1 is 105 degree

Angle 2 is 75 degree

Answer:

a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?

Step-by-step explanation:

Cost minus the charge which is 8 dollars minus 5.50 is the difference in which you divide 80 by it. 8-5.50= 2.5.     80 divided by 25 = 32. Hope this is the answer you're looking for.

Answer/Step-by-step explanation:

Perimeter of a right triangle : 3 units , 5 units, 4 units

Perimeter = 3 + 4 + 5 = 12

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Surfaces of a three-dimensional figure: 5ft, 7 ft, 3 ft

Surfaces area: 2(7*3)+2(7*5)+2(3*5)

= 142 square feet

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Volume of a three-dimensional figure: 4m , 10 m , 3 m

Volume = 10 * 4 * 3 = 120 cubic meter

~Lenvy~

Answer:

Step-by-step explanation:

Perimeter of a triangle = sum of 3 sides

= 3 + 4 + 5

= 12 units

Surfaces of a three-dimensional figure = sum of 3 pairs of surfaces

= 5*7*2 + 7*3*2 + 3*5*2

= 70 + 42 + 30

= 142 square fts

Volume of a three-dimensional figure = length*width*height

= 4*10*3

= 120 m^3

The total amount accrued, principal plus interest, with compound interest on a principal of $4,000.00 at a rate of 2.48% per year compounded 4 times per year over 1 years is $4,100.13.

Given Data

A = P + I where

P (principal) = $4,000.00

I (interest) = $100.13

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.48/100

r = 0.0248 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 4,000.00(1 + 0.0248/4)^(4)(1)

A = 4,000.00(1 + 0.0062)^(4)

A = $4,100.13

Answer:We are asked to evaluate Marlena's solution in solving the expression below: 2x+5 = -10 -x

The first step is to re-write the expression and transpose same terms in the left side while all numbers are transferred to the right side such as shown below:

Step 0: 2x+5 = -10 -x

Step 1: 2x + x = -10 -5

Step 2: 3x = -15

Step 3: x =-15/3

The answer is x=-5.

Answer:

  x = -8

Step-by-step explanation:

The sum of arcs of a semicircle is 180°. That means the arc whose measure is -11x+12 has a measure of 180° -80° = 100°.

  -11x +12 = 100

  -11x = 88 . . . . . . subtract 12

  x = -8 . . . . . . . divide by -11

Answer:

753.98224

Step-by-step explanation:

v=pie r^2 h/3=piex6^2x20/3=753.98224

Step-by-step explanation:

Hey there!

3x + (4x+5)° = 180° {sum of co-interior angle 180°}

7x= 180°-5°

7x= 175°

[tex]x = \frac{175}{7} [/tex]

Therefore, X= 25°.

Answer:

56.6 ft

Step-by-step explanation:

→ Perimeter = All sides added together

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

Answer:

56.6

Step-by-step explanation:

Perimeter is just adding all the outer value of an shape

So we add all the answers

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

but there is easier way

5.2 x 2 = 10.4

7.7 x 6 = 46.2

10.4 + 46.2 = 56.6

at the end don't forget to add "ft"

Answer = 56.6 ft

Answer:

452.16 m²

Step-by-step explanation:

Given :-

Radius = 12 m

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 12 x 12

= 3.14 x 144

= 452.16 m²

Solution :-

452.16 m²

Answer:

144

Step-by-step explanation:

A=πr^2

Where:

A

is the Area of the Circle: what we are solving for in this problem.

r

is the Radius of the Circle: 12 meters for this problem

Substituting and calculating

A

gives:

A=π(12)^2m^2

A=π144m^2

A= 144m^2

This circle would have an area of 144 square meters.
