State whether or not each of the triangles are similar (use either AA, SSS, or SAS)
Answer:
ΔABC and HGF are similar.
Step-by-step explanation:
In the given triangles ABC and HGF,
If both the triangles are similar,
Their corresponding sides will be proportional.
[tex]\frac{AB}{GH}=\frac{BC}{FG}= \frac{AB}{HF}[/tex]
[tex]\frac{72}{12}=\frac{48}{8}= \frac{84}{14}[/tex]
6 = 6 = 6
True.
Therefore, ΔABC and HGF are similar.

The angle of elevation of the top of the building at a distance of 50 m from its foot on a horizontal plane is found to be 60°. Find the height of the building.
Please show your work
Answer:
[tex] \huge \boxed{ \boxed{ 50 \sqrt{3} \: or \: 86.6}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:trigonometryPEMDASlet's solve:to find the height we need to use tan function because we are given adjacent and angle and we need to figure out opposite (height) [tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]
let opposite be AC
let adjacent be BC
according to the question:
[tex] \quad \: \tan( {60}^{ \circ} ) = \dfrac{AC}{BC} [/tex]
now we need a little bit algebra to figure out AC (height)
[tex] \sf \: substitute \: the \: given\: value \: of \: BC : \\ \tan( {60}^{ \circ} ) = \frac{AC}{50} [/tex][tex] \sf sustitute \: the \: value \: of \: \tan( {60}^{ \circ} ) \: i.e \: \sqrt{3} : \\ \sqrt{3 } = \frac{AC }{50} [/tex][tex] \sf cross \: multiplication: \\ 50 \sqrt{3} = AC[/tex][tex] \sf swap \: sides \: (your \: wil) : \\ AC = 50 \sqrt{3} \\AC = 86.6 \: ( \sf \: decimal \: if\: needed)[/tex][tex]\text{we are done!}[/tex]

Step-by-step explanation:
Deon invests $15,000 in a savings account that pays 3% simple interest. How much will be in the account after 4 years if Deon makes no withdrawals or deposits to the account?
Answer:
$16,800
Step-by-step explanation:
The amount that would be in the account = amount deposited + interest earned on deposit
interest earned on deposit can be determined by determining the simple interest
Simple interest = principal x time x interest rate
principal = the amount deposited = $15,000
Time = the duration of the deposit = 4 years
interest rate = the percentage on deposit that would be earned = 3%
15,000 x 0.03 x 4 = $1,800
The amount that would be in the account = $15,000 + $1800 = $16,800

Answer:
x = 3
Step-by-step explanation:
Hi there,
We know that the value of ∠ABD and ∠DBC are the same because BD bisects it. Therefore, we can set both of the angle values equal to each other to find the value of x.
9x = (8x + 3)
x = 3
Hope this answer helps. Feel free to ask questions. Cheers.

Answer:
She made $1230 more on printed shirts than plain shirts in 25 weeks.
Step-by-step explanation:
Hi,
Okay, I have to admit, this is pretty complicated. But, it's not impossible :) First things first, we know that the equation in the table is the number of shirts sold after W number of weeks. We know that we need to, first, find the total number of shirts sold in 25 weeks.
The equation for the plain shirts is 5w -4. Let's start with that.
Plugin 25 for w to find the total number of plain shirts sold after 25 weeks.
5w - 4
5(25) - 4
= 121
She sold 121 plain shirts after 25 weeks. But we're not done yet, we still have to see how much money she made after selling 121 plain shirts. To do this, we have to multiply the total number of plains shirts sold by 15. (we know that each plain short costs $15, that's why we're multiplying it by 121)
When you do this...
121 x 15
You get...
$1815
She got $1815 after 25 weeks just for selling plain shirts.
Now, let's find the total cost of printed shirts after 25 weeks.
The equation for the printed shirts if 8w + 3.
8w + 3
8(25) + 3
= 203
She sold 203 printed shirts in 25 weeks. Let's find the cost. Each printed shirt costs $15 so we need to multiply 203 by 15.
203 x 15
You get...
$3045
She made $3045 by selling printed shirts in 25 weeks.
Now, we have to subtract $3045 by $1815 to find how much more she made. You get...
3045 - 1815
= $1230
She made $1230 more on printed shirts than plain shirts in 25 weeks.
I really hope this helps :)

Solve w+ 13 = 11w - 7. w =
Answer:
5w+13
Step-by-step explanation:
w+13=11w-7w
=w+13+11w+-7w
=(w+11w+-7w)+(13)
=5w+13
Answer:
w=2
Step-by-step explanation:
Let's solve your equation step-by-step.
w+13=11w−7
Step 1: Subtract 11w from both sides.
w+13−11w=11w−7−11w
−10w+13=−7
Step 2: Subtract 13 from both sides.
−10w+13−13=−7−13
−10w=−20
Step 3: Divide both sides by -10.
−10w/−10 =−20/−10
Answer:
w=2
