Mathematics

klasskru [66]3 years ago

Answer:

Step-by-step explanation:

We can use to formula of finding the area of a trapezoid in this problem.

<em>Formula: </em>[(<em>b</em>1 + <em>b</em>2)/2] *<em>h,</em> where <em>b</em>1 and <em>b</em>2 are the bases and <em>h</em> is the height.

<em>b</em>1 can be the bottom base, which has a length of 21 units.

<em>b</em>2 can be the top base, which has a length of (21-9-3)+3 = 12 units.

<em>h</em> has a length of 8, since it is the height.

Plugging these into the formula, we can see that the area of the entire figure is (21+12)/2 * 8 = 33/2 * 8 = 33*4 = <u>132</u><em> </em>units².

Hope this helps! :)

Answer:

132 square units

Step-by-step explanation:

First, I would figure out the areas of the right triangles

Left triangle:  1/2(6x8) =24 units²

Right triangle:  1/2(8x3) = 12 units²

entire rectangle between triangles: 12x8 = 96 units²

add all areas together:  24+12+96 = 132 units²

Solve the equation<br><br> c/7=6 1/7
Softa [21]
c/7 = 6 1/7 ⇒ c = 43 ⇒ 43/7 = 6 1/7

Convert mixed fraction into a simple fraction

6 1/7 ⇒ (6 * 7 + 1)/7 = 43/7 

c/7 = 43/7

proportionality: 

a/b = c/d where    ad = bc

a = c 
b = 7 
c = 43
d = 7          

ad = bc ⇒ c7 = 7*43 ⇒ c7 = 301 ⇒ 7c/7 = 301/7 ⇒ c = 43

Margaret wants to cover a footrest in the shape of a rectangular prism with cotton fabric. The footrest is 18 in. 12 in. 10 in.
user100 [1]

Answer:

No, she cannot completely cover the footrest.

Step-by-step explanation:

First of all, we need to find the total surface area of the prism to be covered using the cotton cloth

the total surface area of the prism is

A = 2wl + 2lh + 2hw,

l is the length of the prism = 18 in,

w= width of the prism = 12 in,

h is the height of the prism = 10 in

hence A = 2(12 \times 18 ) + 2(18 \times 10) + 2(10 \times 12)=1032in^{2}

We need to convert the area of the fabric to be in the same unit as that of the prism

Area of cotton fabric = 1 yd^{2}= 1296 in ^{2}

since the surface area of the foot rest is more than the area of fabric she has, she cannot completely cover the footrest

Prove that the value of the expression: 731^2−631^2 is divisible by 100
Ivanshal [37]

Answer:

Step-by-step explanation:

731² - 631² is the difference of squares.

731² - 631² = (731+631)(731-631) = 1362×100

therefore, 731² - 631² is divisible by 100

write an equation in point slope form for the line that has a slope of 9/4 and contains the point (3,-4)
denis-greek [22]

Answer:

y+4 = 9/4(x-3)

Step-by-step explanation:

The point slope form of an equation is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

Substituting in what we know

y--4 = 9/4(x-3)

y+4 = 9/4(x-3)
