Answer:(d)

Step-by-step explanation:

Given

AB=AC

[tex]\therefore[/tex] We can write

[tex]\angle ABC=\angle ACB\ \quad \text{[angles corresponding to equal sides are equal]}[/tex]

[tex]\angle ABC=\angle BCA=\angle ACB=65^{\circ}[/tex]

Answer:

J

Step-by-step explanation:

check by multiplying each x value by 4

Answer:

D (J)

Step-by-step explanation:

y=4x is basically multiplying the x value by 4; 10*4 is 40, 20*4 is 80, and so on.

Answer:

12.75feet (12¾)

Step-by-step explanation:

7t+1+5t+8=162feet

12t+9=162feet

12t=162-9

=153

t = 153÷9

=12.75feet (12¾feet)

Answer:

350

Step-by-step explanation:

so the first step is to find the values of each of them

7x10^6=7000000

2x10^4=20000

then we divide 7000000 by 20000

7000000/20000=350

so the answer is 350

hope this helps :)

Answer:

I believe its a triangular prism

Answer:

Triangular Prism

Step-by-step explanation:

Fold the shape at the dotted lines and you will see what shape it is. It's hard to explain but look up Triangular Prism and it will make sense.  

Answer:

(n + 1) (5m + 4)

Step-by-step explanation:

⇒ (n + 1) (5m + 4)

⇒ 5mn + 4n + 5m + 4

⇒ 5mn + 5m + 4n + 4

Answer:

(n + 1)(5m + 4)

Step-by-step explanation:

Given

5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )

= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term

= (n + 1)(5m + 4)

Answer:

if its a parabola on a grahp grab two points x and y and divide y/x and the answer that you get is the slope if you dont know what x and y are it is basically X is a number from the line that goes straight across on a line you can memorize it by running and y is the one that is upwards you can memoriza that by jumping im triying my best to explain sorry if doesnt make sense

Step-by-step explanation:

[tex]\frac{2}{3}[/tex]

When graphed, the equation 2x - 3y = -3 forms a linear function. The slope of that line is 2/3.

Answer: Yes

Step-by-step explanation:

Answer:

The maintance cost and the value will be the same in 9 years.

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

[tex]y(t) = y(0)(1 + r)^t[/tex]

In which r is the rate of change.

The value starts at $20,000 and decreases by 15% each year.

This means that [tex]V(0) = 20000, r = -0.15[/tex]

So

[tex]V(t) = V(0)(1 + r)^t[/tex]

[tex]V(t) = 20000(1 - 0.15)^t[/tex]

[tex]V(t) = 20000(0.85)^t[/tex]

The maintance cost is $500 the first year and increases by 28% per year.

This means that [tex]M(0) = 500, r = 0.28[/tex]. So

[tex]M(t) = M(0)(1 + r)^t[/tex]

[tex]M(t) = 500(1 + 0.28)^t[/tex]

[tex]M(t) = 500(1.28)^t[/tex]

When will the maintenance cost and the value be the same.

This is t for which:

[tex]V(t) = M(t)[/tex]

So

[tex]20000(0.85)^t = 500(1.28)^t[/tex]

[tex]\frac{(1.28)^t}{(0.85)^t} = \frac{20000}{500}[/tex]

[tex](\frac{1.28}{0.85})^t = 40[/tex]

[tex]\log{(\frac{1.28}{0.85})^t} = \log{40}[/tex]

[tex]t\log{(\frac{1.28}{0.85})} = \log{40}[/tex]

[tex]t = \frac{\log{40}}{\log{(\frac{1.28}{0.85})}}[/tex]

[tex]t = 9[/tex]

The maintance cost and the value will be the same in 9 years.

Answer:

[tex]\frac{20}{13}[/tex] + [tex]\frac{5}{13}[/tex] [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5}{4-\sqrt{3} }[/tex]

To rationalise the denominator, multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of 4 - [tex]\sqrt{3}[/tex] is 4 + [tex]\sqrt{3}[/tex]

= [tex]\frac{5(4+\sqrt{3}) }{(4-\sqrt{3})(4+\sqrt{3}) }[/tex]

= [tex]\frac{20+5\sqrt{3} }{16-3}[/tex]

= [tex]\frac{20+5\sqrt{3} }{13}[/tex]

= [tex]\frac{20}{13}[/tex] + [tex]\frac{5}{13}[/tex] [tex]\sqrt{3}[/tex]

Answer:

1. Just do 36-9=27 so 36-27=9. The answer would be 27

Step-by-step explanation:

Answer:

4)

Plug it in and Just subtract 36 with 9.

You get 27.

So, 36 - 27 = 9

Answer:

C

Step-by-step explanation:

Answer:

y=67.7 Degrees

Step-by-step explanation:

You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:

Tan(y)= 100/41

We then inverse tan to isolate y

y=tan^-1 100/41

y=67.7 Degrees

Note: Use a calculate to find the final answer

Answer:

-2.1f-18

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

"6 times as many birds..." in other words 6 x 2

The number of turtles that was sold by the pet store given the number of birds sold is 12.

Multiplication is a mathematical operation that involves determining the product of two or more numbers. The sign used to represent multiplication is x.

Number of turtles were sold = 2 x 6 = 12

Answer:A he is correct because the inner circle is a dilation of the outer circle

Step-by-step explanation: just did the test

The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.

The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.

Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.

Troy is accurate if he claims the two circles are similar.

Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Answer:

55m²

Step-by-step explanation:

So for the two small triangles, I did 10x3 =30  and divided by 2 to get 15

For the two big triangles, did 10x8 and got 80/2 =40

To find area of a triangle, it's: base x height, then divided by 2.
