Answer: $y=\frac{1}{2} x+2$

Step-by-step explanation:

The format for these equations are y=mx+b. Find the slope, which is the change in y over the change in x. When you apply this formula, you get 1/2. To find the y-intercept, just count from the origin to the place the line meets the y-axis, which is 2. Putting it together, you get the equation $y= \frac{1}{2}x+2$

What is the surface area, in square centimeter, of the square pyramid?

AnnZ [28]

Surface area = 56 cm2

Explanation:

Area of square base = Side x Side = 4 x 4 = 16 cm2

Area of triangle = 1/2 x Base x Height = 1/2 x 4 x 5 = 10 cm2
Area of 4 triangles = 10 x 4 = 40 cm2

Surface area of pyramid = 16 + 40 = 56 cm2

(8m-3n)^2 - (4m+3n)^2

natulia [17]

Answer:

$48m^2-72mn$

Step-by-step explanation:

We need to solve $(8m-3n)^2 - (4m+3n)^2$

We know that,

$(a+b)^2=a^2+b^2+2ab\\\\(a-b)^2=a^2+b^2-2ab$

Using the above formula,

$(8m-3n)^2 - (4m+3n)^2=(8m)^2+(3n)^2-2(8m)(3n)-[(4m)^2+(3n)^2+2(4m)(3n)]\\\\=64m^2+9n^2-48mn-(16m^2+9n^2+24mn)\\\\=64m^2+9n^2-48mn-16m^2-9n^2-24mn\\\\=48m^2-48mn-24mn\\\\=48m^2-72mn$

So, the final answer is $48m^2-72mn$ .

The parents’ club has $2,500 to invest in printed shirts to sell at their fundraiser. What is the maximum number of shirts that

VikaD [51]

Total amount to be invested = $2,500.

First given price for a printed shirt = $18.

Number of shirts that they can buy = Total money ÷ Price of each shirt.

a) For unit price $18 number of shirts can buy = 2,500/18 = 138.89, so approximately 138 ( because it's less than 139).

Therefore, with unit price $18 the maximum number of shirts can buy = 138 shirts.

a) For unit price $15 number of shirts can buy = 2,500/15 = 166.67, so approximately 166 ( because it's less than 167).

Therefore, with unit price $15 the maximum number of shirts can buy = 167 shirts.

a) For unit price $11 number of shirts can buy = 2,500/11 = 227.27, so approximately 227 ( because it's less than 228).

Therefore, with unit price $11 the maximum number of shirts can buy =227 shirts.

Therefore, with least unit price $11 , maximum number of shirts could be buy and that is 227 shirts which is over 200.
