Answer:

Step-by-step explanation:

14x3x2=84

(12x10x2)/2=12x10=120

120+84=204

Answer:

SA=724 mm^2

Step-by-step explanation:

14*13==182,*2=364

14*10=140

10*12=120, *1/2=60, *2=120

364+140+120=724

SA=724 mm^2

Answer:

Step-by-step explanation:

Answer:

2x(x+y)(x-y)

Step-by-step explanation:

Given the expression;

(x+y)² + 2(x+ y)(x- y) + (x– y)²

Factorize

(x+y)² + (x+ y)(x- y) +   (x+ y)(x- y) + (x– y)²

= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]

= (x+y)(x-y)(x+y+(x-y))

= (x+y)(x-y)(x+y+x-y)

= (x+y)(x-y)(2x)

hence the expanded form is 2x(x+y)(x-y)

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:

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

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.

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:

yes

Step-by-step explanation:

like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

Answer:

If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay

Answer:

I think it's 12..?

Step-by-step explanation:

Since they're supposed to be congruent and x lines up with the side on the other triangle that is 12. I think that means that x would also have to equal 12 for them to be congruent.

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:

A = 28.3 cubic inches; P = 20.1 inches

Step-by-step explanation:

Looks like 3/4 of a full circle

The area of a circle is calculated with the formula: [tex]\pi r^{2}[/tex]

Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.

The radius is given as 3 inches

Area = [tex]3.14*3^{2} = 3.14*9 = 28.26[/tex] cubic inches = 28.3 cubic inches

------------------------

Perimeter is calculated with [tex]2\pi r[/tex].

But this is 3/4 of a circle with an additional two 3-inch sides

Perimeter = [tex]\frac{3}{4}*2\pi r[/tex] + 2(3) = 14.1 + 6 = 20.1 inches

Answer:

Step-by-step explanation:

Answer:

x = 3 n, y = -2 n, n element Z

Step-by-step explanation:

Answer:

x = 82

y = 98

z = 87

Step-by-step explanation:

By inscribed angle theorem:

[tex] x\degree =\frac{1}{2} (58\degree + 106\degree) [/tex]

[tex] x\degree =\frac{1}{2}\times 164\degree [/tex]

[tex] x\degree =82\degree [/tex]

[tex] x =82[/tex]

x° and y° are the measures of the opposite angles of a cyclic quadrilateral.

Opposite angles of a parallelogram are supplementary.

Therefore,

x° + y° = 180°

82° + y° = 180°

y° = 180° - 82°

y° = 98°

y = 98

Similarly,

93° + z° = 180°

z° = 180° - 93°

z° = 87°

z = 87

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:

2y - x - 3xy

Step-by-step explanation:

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.
