d = 250

Answer:

Step-by-step explanation:

[tex]a_{n}=a_{1}+(n-1) d\\n=9\\12=0+(9-1)d\\8d=12\\d=\frac{12}{8}=\frac{3}{2}\\again\\27=0+(n-1)*\frac{3}{2}\\n-1=27*\frac{2}{3}=18\\n=18+1=19[/tex]

Answer: 1/2 times 6x equals 3x  and then you do 1/2 times 4 and that equals 2 then multiply the 3 and 4 in the parenthesis and that is 12 then add 12 to the 3 and 2 and your answer is 17.

Answer:

Dora has to paint a total ol 60m

Step-by-step explanation:

4x5x3

4x5= 20

20x3=60

We can find the slope using any two points on the line. Readily identifiable are the points (2, 0) and (0, 3), from which we can find the slope:

[tex]\text{slope} = m=\frac{y_2-y_1}{x_2-x_1} \\ m = \frac{3-0}{0-2} = -\frac{3}{2}.[/tex]

The y-intercept is the y value when x = 0, which we already know is 3. So, the slope-intercept equation of this line is:

[tex]y=-\frac{3}{2}x+3.[/tex]

Answer:

5

Step-by-step explanation:

Answer:

$1,440

Step-by-step explanation:

1,200 / 10 = 120. 120 is 10%. So this means that 5% is $60. 60 x 4 = 240.

1,200 + 240 = 1,440

Answer:

-3/4

Step-by-step explanation:

The slope is -3/4

The line goes down three and four left.  

Answer: (5,18); (-5,38)

Step-by-step explanation:

x^2-2x+3=-2x+28

x^2-25=0

(x-5)(x+5)= 0

-2(5)+28= 18

-2(-5)+28=38

(5,18)(-5,38)

Ok it might take a long time but I'll get it done for you lol

Step-by-step explanation:

Answer:

The base angles are 64. The top angle is 52

Step-by-step explanation:

Since this is an icoseles triangle, the base angles are equal so:

8x - 16 = 6x + 4

8x - 6x = 4 + 16

2x = 20

x = 10

8x - 16

8(10) - 16

80 - 16

64

The top angle (x)

x + 64 + 64 = 180

x + 128 = 180

x = 52

Answer:

d. y = -⁷/6x - 7

Step-by-step explanation:

✔️First, find the slope (m) using two points on the line, (-6, 0) and (0, -7):

Slope (m) = change in y/change in x

Slope (m) = (-7 - 0)/(0 - (-6))

Slope (m) = -7/6

✔️Determine the y-intercept (b):

The line intercepts the y-axis at -7. Therefore,

b = -7.

✅To write the equation, substitute m = -⁷/6 and b = -7 into y = mx + b

Thus:

y = -⁷/6x + (-7)

y = -⁷/6x - 7

Step-by-step explanation:

In a pyramid, there is only one base that touches the ground.

However, in a prism, there are two bases, two of the same ends.

The front of the name of the shape also hints:

If it's an octagonal prism, there are two octagon bases.

If it's a hexagonal pyramid, there is one hexagon base.

Answer: 1725 ft^2

Step-by-step explanation:

Rectangle part is 30*50 or l*w = 1500

Triangle is 15*30/2=225

Add the two to get area

1500+225=1725

Answer:

37

Step-by-step explanation:

Because 180 is a straight line.

Subtract 143 from 180 amd get 37.

Answer:

Depth is 4 feet.

Step-by-step explanation:

Given:

Length of an aquarium is 2.3 feet

Width of an aquarium is 1.2 feet

Volume of an an aquarium is 11.04 cubic feet

To find: depth of an aquarium is 2.3 feet

Solution:

If [tex]l,b,h[/tex] denote length, width and height of a cuboid then volume (V) of a cuboid is equal to [tex]lbh[/tex]

[tex]l=2.3[/tex] feet

[tex]b=1.2[/tex] feet

[tex]V=11.04[/tex] cubic feet

[tex]11.04=2.3(1.2)h\\h=\frac{11.04}{2.3(1.2)}\\h=\frac{11.04}{2.76}[/tex]

[tex]h=4[/tex] feet

Therefore,

depth is 4 feet.

Answer: 480 in.

Step-by-step explanation:

Given

The width of the sandbox is 48 in.

The length of the sandbox is four times the width

[tex]\therefore L=4\times 48=192\ in.[/tex]

Perimeter is the sum of the sides of the shape

The perimeter of the box is

[tex]P=2[48+192]=480\ in.[/tex]

Answer:

the  perimeter of the sandbox is 480 inches

Step-by-step explanation:

The computation of the perimeter of the sandbox is shown below:

Since the width is 48 inches

And, the length would be four times the width i.e.

= 4 × 48

= 192 inches

Now the perimeter of the sandbox is

= 2( length + width)

= 2 (192 inches + 48 inches)

= 480 inches

Hence, the  perimeter of the sandbox is 480 inches
