3. What method can be use to prove the triangles below are congruent?

options:
congruent by sss
congruent by hl
congruent by sas
not congruent

Answer:

110888

Step-by-step explanation:

v=surface area *radius

v=528*21=110888cm3

Answer: the height is 4

I think you make mistakes

but that is the height

Step-by-step explanation:

h =height=?cm

R=radius=21cm

A =surface area 528cm

Answer:

Step-by-step explanation:

They are both C3H8

There are

3 carbons

8 hydrogens

Or put in the form that the table is written

Element          # of atoms  

Hydrogen           8

Carbon                3

Answer:

You are going to take the shape and flip if across the x Axis, reversing it essentially. then you will move it up 4, so of it is a square with one corner at (2,3) it will go to (5, 7) and all the other point will move together if I remember right. I last did this 3 years ago, I hope I help, next time show the whole graph with the number and I would have put a visual to show you the answer. Good luck

Answer:  -10; -2; 0

Step-by-step explanation:

≥ means greater or equal than.

-10 is equal -10, true.

-14 is less than -10, so false.

-2 is greater than -10, true

0 is greater than -10, true

so the answer is -10, -2 and 0 can make this inequality true.

Answer:45

Step-by-step explanation:

Well just take the sim of the two given angles then subtract them from the total measure of the triangle which is 180

Answer:

When x=2

Step-by-step explanation:

Well in the first one it tells you that 2x is 90.

In the second it's y=40x+10

So you plug 2 in as the x.

y=40(2)+10

y=80+10

y=90

Hope this helps

i hope it help u

Step-by-step explanation:

x=180-(85+63)

x=180-148

x=32

Answer:

y=5.4

Step-by-step explanation:

So first we cross multiple.

2*112=35*(y+1)

224=35y+35

-35 on both sides

189=35y

÷35 on both sides

5.4=y

Answer:

the last one is the answer I thin

Answer:

D

Step-by-step explanation:

Hey There!

Remember in order for the relation to be a function none of the x values can repeat

For the first one the x value 0 repeats therefore it is not a function

for the second one the x value -7 repeats thus meaning that its not a function

for the third one the x value 6 repeats hence, it is not a function

for the last one each input has a different output therefore it is a function

Answer:

Step-by-step explanation:

a=1

r=-6/1=-6

[tex]S_{7}=a\frac{1-r^n}{1-r} =1\frac{1-(-6)^7}{1-(-6)} \\=\frac{1+6^7}{1+6} \\=\frac{1+279936}{7} \\=\frac{279937}{7} \\=39991[/tex]

Answer:

I think it's c

Step-by-step explanation:

Answer:

De acuerdo a la información proporcionada, dado que se van a repartir 5 barritas entre 8 niños, se tiene que dividir las barritas entre el número de niños y a partir de aquí, se construye la fracción 5/8. Esto lo que indica es que cada barrita se divide en ocho pedazos y cada niño recibiría 1/8 de cada barrita y para las 5 barritas sería:

1/8*5=5/8

Given:

A coordinate pair was dilated from (-3, 2) to (-6, 4).

To find:

The scale factor.

Solution:

We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.

The value of scale factor is:

[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]

[tex]k=\dfrac{-6}{-3}[/tex]

[tex]k=2[/tex]

Therefore, the scale factor is 2.

Answer:

I believe its B, sorry if im wrong

Step-by-step explanation:

Answer:

-48 ; - 16

Step-by-step explanation:

Given the expression :

X /4 = - 12

Multiply both sides by 4

X/4 * 4 = - 12 * 4

X = - 48

For the second :

X/2 = - 8

Multiply both sides by 2

X/2 * 2 = - 8 * 2

X = - 16

Answer:

60 were left with Ken, and that is 75%

Step-by-step explanation:

80-10 = 70

70-10 = 60

60/80 = x/100, simplify & cross multiply

6/8 = x/100

600 = 8x

x = 75

Answer:

x=28

Step-by-step explanation:

I am assuming the mean is arithmetic mean. So we first add up the numbers:

6+10+12+18+16+x

=22+10+30+x

=22+40+x

=62+x

Then since there's 6 numbers in total, we have an equation:

[tex]\frac{62+x}{6}=15\\62+x=90\\x=28[/tex]

The answer is 28!

Have a nice day! :)

Complete question :

Laura and Martin obtain a 30-year, $180,000 conventional mortgage at 10.0% on a house selling for $210,000. Their monthly mortgage payment, including principal and interest, is $1566.00. Determine the total amount they will pay for their house. How much of the cost will be interest? How much of the first payment on the mortgage is applied to the principal?

Answer:

$563760 ; $383760 ; $66

Step-by-step explanation:

Given that:

Monthly mortgage payment = $1566

Period = 30 years

Number of months in period = (30 * 12) = 360

Principal = $180,000

1.)

Total amount paid :

Monthly payment * period

$1566 * 360 = $563760

2.)

Total amount paid = Principal + Interest

Interest = Total amount paid - principal

Interest = $563760 - $180000

Interest = $383760

3)

First payment = 1566

Interest rate = 10% per annum = 0.1 / 12 = 0.0083333

monthly interest: 180,000 * 0.0083333 = 1500

Principal = 1566 - 1500 = $66

umm whichever grade this is I don't know

4,368 please I hope it is correct I used a calculator

Answer:

M= ([-1],[1/2])

The number in the green box is -1

Step-by-step explanation:

M= ([x1+x2/2], [y1+y2/2])

M= ([2+(-4)/2], [5+1/2])

M= ([-2/2, 6/2])

M= ([-1, 3])

Answer:

False

Step-by-step explanation:

Based on what is stated in the question :

Expressing the worded equation Mathematically,

(5x - 7) / 2 = y

If y = 28

(5x - 7) / 2 = 28

Cross multiply

5x - 7 = 28 * 2

5x - 7 = 56

5x = 56 + 7

5x = 63

x = 63 / 5

x = 12.6

Hence, x ≠ 9

Answer:

its correct don't sweat
