ABF= 28 degrees
BCD= 28  degrees since vertical angle are congruent
ABC= 180 -28 = 152 degrees

X is 21 because vertical angles are congruent to each other so 4x=84. X=21 when you divide by 4 on each side.
KMH is 96 because a line is 180. 180-84=96
CBE is 118 because a line is 180. DBE is 90 so ABE also has to be 90. To find ABF it's 90-62 which is 28. CBD is also 28 because that's the vertical angle from ABF and that's congruent. so 90+28= 118. Hope this helps!
Happy Studying!

The bells are adding a new room to their house. The room will be a cube with volume 8,000 ft^3. They are going to put in hardwoo
Mandarinka [93]

Answer:

$4000

Step-by-step explanation:

Given that :

Volume of cube = 8000 ft³

Charge per ft² = $10

Recall, volume of a cube = a³

Where a = edge

Hence,

a³ = 8000

Take the cube root of both sides

a = 20

Hence,

Volume = 20 * 20 * 20

The Area of the floor will be :

20 * 20 = 400 ft²

If charge per ft² = $10

400 ft² = ($10 * 400) = $4000

\bf \qquad \qquad \qquad \qquad \textit{function transformations}

\begin{array}{rllll}

f(x)=&{{  A}}({{  B}}x+{{  C}})+{{  D}}
\\ \quad \\

now... with that template in mind, let's see yours

A is twice as large as in f(x), thus the graph shrinks twice as much in g(x)

Nora's paper airplane flew 9 1/6 feet. That was 2 3/4 feet farther than Max's plane flew. Write and solve an equation to show ho
stepan [7]

Answer:

Max's paper airplane flew \frac{77}{12} feet or 6\frac{5}{12} feet.

Step-by-step explanation:

As Nora's paper airplane flew 9 1/6 feet

i.e.

9\frac{1}{6}=\frac{55}{6}

Nora's paper was farther than Max's plane flew by = 2 3/4 feet

i.e.

2\frac{3}{4}=\frac{11}{4}

Thus the equation to show how far Max's paper airplane flew is:

\:\:9\frac{1}{6}-2\frac{3}{4}

=\frac{55}{6}-\frac{11}{4}

\mathrm{Least\:Common\:Multiplier\:of\:}6,\:4:\quad 12

\mathrm{Adjust\:Fractions\:based\:on\:the\:LCM}

=\frac{110}{12}-\frac{33}{12}

\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}

=\frac{110-33}{12}

\mathrm{Subtract\:the\:numbers:}\:110-33=77

=\frac{77}{12}

=6\frac{5}{12}

Therefore, Max's paper airplane flew \frac{77}{12} feet or 6\frac{5}{12} feet.
