Answers

Answer:

D.) 200ft²

Step-by-step explanation:

The formula for the area of a trapezoid:

[tex]A=\frac{1}{2} (b_{1}+b_{2})h[/tex]

where:

[tex]b_{1}[/tex] and [tex]b_{2}[/tex] are the basesh is the height

Insert the given values:

[tex]A=\frac{1}{2}(16+24)*10[/tex]

Simplify the equation using PEMDAS. Simplify parentheses:

[tex]A=\frac{1}{2}*40*10[/tex]

Simplify multiplication:

[tex]A=\frac{1}{2}* 400[/tex]

Simplify multiplication. Use the rule [tex]\frac{a}{b}*c=\frac{ac}{b}[/tex] :

C.
Find the length of the height. Do not round to a decimal.

Answers

Answer:

Area: T = 18

a.  The triangle area using Heron's formula: T=  sqrt(s(s−a)(s−b)(s−c) )

​b. 2[tex]\sqrt{10}[/tex]  

c. h = 5.69

d. T = 18

 

Step-by-step explanation:

a. T=  sqrt(s(s−a)(s−b)(s−c) )

T=sqrt( 11.16(11.16−10)(11.16−6)(11.16−6.32) )

​T=  sqrt(324 )

​T =18

So if I’m thinking correctly we subtract 180 from 217 which gives us 37. We then add that to 104 and subtract the sum from 180 which gives us b. So,

180-104+37
180-141=39

So b should equal 39 degrees, to check we add all the respective angles up,

104+39+37=180

Answers

-33.33333333333333 %A change from 27 to 18 represents a negative change (decrease) of -33.33333333333333%

Use the formula found below on this webpage to find the percent changeby replacing the given values:Percent change = New - Old|Old|  100%Percent change = 18 - 27|27|  x 100 = -927  x 100 = -33.33333333333333decrease)

Where: 27 is the old value and 18 is the new value. In this case we have a negative change (decrease) of -33.33333333333333 percent because the new value is smaller than the old value.

The Answer is: -33.33333333333333% or 33.3

Find the solution to the system of the equations shown below: y = -4x + 11
y=1/2x+2​

Answers

Hello!

[tex]\large\boxed{x = 2}[/tex]

Set the two equations equal to each other to solve:

y = -4x + 11

y = 1/2x + 2

-4x + 11 = 1/2x + 2

Add 4x to both sides:

-4x + 4x + 11 = 1/2x + 2 **Convert 4x into 8/2x***

11 = 9/2x + 2

Subtract 2 from both sides:

11 - 2 = 9/2x + 2 - 2

9 = 9/2x

Divide both sides by 9/2:

9 * (2/9) = 9/2x * (2/9)

x = 2.

The sum of two complementary angles is 90 degrees.

Angle A  +  Angle B = 90

Let Angle B = X

5x + 2 + x = 90

Combine like terms:

6x +2 = 90

Subtract 2 from both sides:

6x = 88

Divide both sides by 6:

x = 88/6

x = 14.67

Angle B = 14.67 degrees ( rounded to the nearest hundredth)

The swimming team has 84 members. The number of boys on the team is six more than twice the number of girls. How many boys and girls are on the team?

Answers

Answer:

the number of boys and girls on a team is 58 and 26 respectively

Step-by-step explanation:

Given that

Total members in swimming team is 84

Let us assume the number of girls be x

so, the number of boys would be

y = 2x + 6

Now the equation is

x + y = 84

x + 2x + 6 = 84

3x = 78

x = 26

And, y = 2 × 26 + 6

= 52 + 6

= 58

Hence, the number of boys and girls on a team is 58 and 26 respectively
