The area is about ____ square inches. ANYONE KNOW THIS!? I need the steps if possible:(

Answer:

To make it easier, lets say Justin = J, Eva = E, and Emma = M. Then, J = E + 7.50 M = J -12 J + E + M = 63 You can substitute for M in the third equation using the second equation, and you get: J + E + J - 12 = 63 Clean it up a little bit and you get: 2J + E = 75 You know J = E + 7.50, so substitute that for J and you get: 2(E + 7.50) + E = 75 2E + 15 + E = 75 3E + 15 = 75 3E = 60 E = 20 ; meaning that Eva has $20. Justin has $7.50 more than Eva, so he has $27.50. Emma has $12 less than Justin, so Emma has $15.50. Double check your answer by making sure they all add up to 63, which they do.

3 in 2:3 is the amount of yellow paint

Figure out how many times to multiply 2 to get 16:

16/2=8

Now, multiply 3 by 8, which would be equal to 24.

Ratio: 16:24

A. 3/12

Step-by-step explanation:

1/4 x 3 for the three different bags and each bag having 1 crayon that's the color green it's 1/4 however due to there being 4 crayons in each bag

the only other answer could be 1/4 when simplified

Answer:

Step-by-step explanation:

1 bag of crayons = 4 crayons = 100% (10/10)

1/4 bag of crayons = 1 crayon = 25% = 1 green crayon per bag

3 bags of crayons = 12 crayons (3 x 4)

if 1 bag has 1 green crayon and there are 3 bags then there are 3 green crayons

A. 3/12

Answer:

It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not. So then the answer is A

Answer:

1:(x-6)²

2:(9-8x)²

Step-by-step explanation:

1: (x-6)(x-6)=(x²-36)

2:(9-8x)(9-8x) = (81 - 64x²)

Answer:

146.96 [tex]m^2[/tex]

Step-by-step explanation:

1. Approach

Divide this figure into two smaller shapes. Calculate the area of these smaller shapes, and then add the results. One can divide this shape into a semi-circle, and a triangle.

2. Area of the triangle

The formula to find the area of a triangle is;

[tex]\frac{base*height}{2}[/tex]

It is given that the base of the triangle is (14m) and the height is (10m). Substitute in these values, and solve for the area,

[tex]\frac{14*10}{2}\\= \frac{140}{2}\\= 70[/tex]

2. Area of the semi-circle

The area of the semi-circle can be found by finding the area of the larger circle, and then divide it by 2, since a semi-circle is half of a circle. The formula for the area of a semi-circle is;

[tex]\frac{(pi)(r^2)}{2}[/tex]

Where (pi) is the constant (3.1415...), (r) represents the radius of the circle, which by definition is half of the diameter. Substitute in the values and solve;

[tex]\frac{(pi)(7)^2}{2}\\= \frac{3.14*49}{2}\\=76.96[/tex]

3. Find the total area;

Now add up the two values for the area of the figures;

Triangle + Semi-circle

= 70 + 76.96

= 146.96

Answer:

r = 4 units

Step-by-step explanation:

Volume of cone = 201.06 cubic units

Height (h) = 12 units

Radius (r) = ?

Thus, formula for volume of cone = ⅓*πr²h

Plug in the values and solve for r

⅓*π*r²*12 = 201.06

r²*4*π = 201.06

r²*12.57 = 201.06

Divide both sides by 12.57

r² = 201.06/12.57

r² = 15.9952267

r = √15.9952267

r ≈ 4 units

Answer:

Area = 139.27 m²

Step-by-step explanation:

Area of the composite figure = area of rectangle + area of semicircle

= (L*W) + ½(πr²)

L = 10 m

W = 10 m

r = ½ of 10 = 5 m

Plug in the values

Area = (10*10) + ½(π*5²)

Area = 100 + 39.27

Area = 139.27 m²

Answer:

40%

Step-by-step explanation:

6/15 = 0.4

0.4x100 = 40%

Answer:

140

Step-by-step explanation:

30% of a number(x) is 105. To find the number(x) we must set up the equation below and solve for x:

0.3=105/x (multiply x)

0.3x=105 (divide by 0.3)

x=350

Solve for 40% of the number by multiplying 0.4 by the number:

350x.4=140
