Answer:

Area cover by solar panel to face = 9,600 feet²

Step-by-step explanation:

Given:

Length of Solar panels = 240 feet

Width of Solar panels = 40 feet

Find:

Area cover by solar panel to face

Computation:

Area of rectangle = Length × Width

Area cover by solar panel to face = Length of Solar panels × Width of Solar panels

Area cover by solar panel to face = 240 × 40

Area cover by solar panel to face = 9,600 feet²

Answer:

Area cover by solar panel to face = 9,600 feet², The panels are about 340 feet Long, and 40 feet Wide. The area of this rectangle is a Length x Width.

Answer:

Angle 4 equals to 120 degrees

Step-by-step explanation:

120 degrees is an obtuse angle

Answer:

∠ 4 = 123°

Step-by-step explanation:

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

sum the 3 angles and equate to 180

9x - 6 + 6x - 1 + 82 = 180

15x + 75 = 180 ( subtract 75 from both sides )

15x = 105 ( divide both sides by 15 )

x = 7

Then

9x - 6 = 9(7) - 6 = 63 - 6 = 57

∠ 4 and 9x - 7 are adjacent angles and sum to 180°, then

∠ 4 + 57° = 180° ( subtract 57° from both sides )

∠ 4 = 123°

Answer:i think it would be 75 cents

Step-by-step explanation:

125 divided by 5 and you get 25, then you fo 25 times 3

Answer:

75 cents

Step-by-step explanation:

x= 5 kilometers

y= 3 cents

y/x= rate of change

3/5= 0.6

125 kilometers is the x variable so y= 0.6(125)

y= 75

Answer:

Mid point:

[tex] = ( \frac{3 + - 5}{2} , \: \frac{1 + 8}{2} ) \\ = ( - 1, \: 4.5)[/tex]

distance:

[tex] = \sqrt{ {( - 5 - 3)}^{2} + {(1 - 8)}^{2} } \\ = \sqrt{64 + 49} \\ = \sqrt{113} \\ = 10.6 \: units[/tex]

slope:

[tex] = \frac{1 - 8}{ - 5 - 3} \\ = \frac{ - 7}{ - 8} \\ = \frac{7}{8} [/tex]

Answer:

89 boys to 71 girls, 89:71, or 89/71

Step-by-step explanation:

x+x+36=320

2x+36=320

2x=284

x=142

This means that there are 142 girls.

142+36=178 boys

Simplify the fraction by dividing both numbers by two.

Answer:

GH 5000

Step-by-step explanation:

Given data

Cost price=  GH 2000.00

Percent profit= 60%

Sales price =???

The sale price can be found  as

% profit= sale-cost/sale*100

60= sale-2000/sale*100

60= 100*sale-200000//sale

60*sale= 100sale-200000

1000sale-60sale= 200000

40sale= 200000

sale= 200000/40

sale= 5000

Hence the sales price = GH 5000

Step-by-step explanation:

the center is (0,8)

(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))

the radius is 7 (or √49)

Answer:

7.193 ft

Step-by-step explanation:

    |\

    |   \

    |      \

    |         \

h  |            \      10 ft

    |               \

    |                  \

    |            46°   \

    ---------------------

For the 46° angle, h is the opposite leg. The hypotenuse is 10 ft. The sine is the trig ratio that relates the opposite leg to the hypotenuse.

sin A = opp/hyp

sin 46° = h/10

h = 10 sin 46°

h = 7.193

Answer: 7.193 ft

Answer:

153.86in^2

Step-by-step explanation:

Area of a circle = πr²

Where : = π = pi = 3.14

R = radius = 14/2 = 7

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

7² x 3.14 = 153.86

A radius is half of the diameter

Answer:

see explanation

Step-by-step explanation:

The nth term ( explicit formula) of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{\frac{4}{3} }{-2}[/tex] = - [tex]\frac{2}{3}[/tex] , then

[tex]a_{n}[/tex] = - 2 [tex](-\frac{2}{3}) ^{n-1}[/tex] ← explicit formula

Answer:

Step-by-step explanation:

The formula for an explicit geometric formula (as opposed to a recursive one) is

[tex]a_n=a_1(r)^{n-1}[/tex] where a(n) is representative of the position of a number in the sequence, a(1) is the first number in the sequence, and r is the common ratio. The common ratio is the same number that must be either multiplied in or divided out to get to the next number in the term. Notice that the top numbers in our sequence are doubling which implies we are multiplying the top numbers by -2, and the bottom numbers are going up by multiples of 3. So our common ratio is -2/3. Try it and see:

[tex]-2(-\frac{2}{3})=\frac{4}{3}[/tex]  and

[tex]\frac{4}{3}(-\frac{2}{3})=-\frac{8}{9}[/tex] etc.

Therefore, the explicit geometric formula for this sequence is

[tex]a_n=-2(-\frac{2}{3})^{n-1[/tex]

You can use this formula to find any number in the sequence; for example, if you wanted to know the 100th number in this sequence, simply replace n with 100 and do the math. That's what an explicit formula is used for.

Answer

a. The volume is multiplied by 4

b. The volume is doubled

Explanation

a. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the radius is doubled, the new volume will be [tex]\pi (2r)^2h/3[/tex], which is equal to [tex]4\pi r^2h/3[/tex]. This means that the volume is multiplied by 4.

b. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the height is doubled, the new volume will be [tex]\pi r^2(2h)/3[/tex], which is equal to [tex]2\pi r^2 h/3[/tex]. This means that the volume is multiplied by 2.

Step-by-step explanation:

Let us assume the cost of the video game be x

There should be two chances

The first one is

that the cost of the video game should be equivalent to the amount given

SO

The return is $0

The second one is

When the cost of the video game is less than the amount you pay

SO, the return change is

= $50 - x

Answer:

The scale “1 inch to 6 feet” is equivalent to the scale “1 to 72,” because there are 72 inches in 6 feet. The scale “1 to 100” would make a scale drawing that is smaller than the scale “1 to 72,” because each inch on the new drawing would represent more actual length.
