HELP PLEASE THANK YOU SO MUCH

Answer:

7g+3t+x

Step-by-step explanation:

You really don't have to do anything to this equation because each number in this equation has a variable, but since 1x is just x you can remove the 1 and you new equation becomes:

7g+3t+x

Answer:

7g+x+3t

Step-by-step explanation:

All you do is remove the 1 because x and 1 are the same

Answer:

volume = 798.58 cm³ (nearest hundredth)

surface area = 678.31 cm³ (nearest hundredth)

Step-by-step explanation:

Volume of a cylinder:   [tex]V=\pi r^2h[/tex]

Surface area of a cylinder:   [tex]SA=2\pi r^2+2\pi rh[/tex]

Circumference:  [tex]C=2\pi r[/tex]

(where r is the radius and h is the height)

Given circumference = 56

⇒ [tex]56 = 2\pi r[/tex]

⇒ [tex]r=\dfrac{56}{2\pi }=\dfrac{28}{\pi }[/tex]

[tex]V=\pi \left(\dfrac{28}{\pi}\right)^2 \times3.2=\dfrac{2508.8}{\pi}=798.58 \textsf{ cm}^3 \textsf{ (nearest hundredth)}[/tex]

[tex]SA=2\pi \left(\dfrac{28}{\pi}\right)^2+56 \times3.2=\dfrac{1568}{\pi}+179.2=678.31 \textsf{ cm}^3 \textsf{ (nearest hundredth)}[/tex]

Step-by-step explanation:

because 25% of 40 is 10

Sorry if wrong :,D

The equation that's been computed shows that the number of cell phones that his family can have will be 2.

From the question, it was stated that the cell phone company charges $50 plus $40 per line each month and that Luke must spend under $170 on his family's cell phone bill each month.

Let the number of cell phones that can be bought be represented by x.

The equation to solve the question will be:

50 + 40(x) < 170

50 + 40x < 170

Collect like terms

40x < 170 - 50

40x < 120

x < 120/40

x < 3

Therefore, the number of cell phones has to be less than 3. Hence, this will be 2.

Answer:

In explanation

Step-by-step explanation:

272 for part A because say you took a test out of 850 and you got a total of 272 of them right then you would of gotten a 32%

200 for 2 because if 75% of them liked pop music and 150 teenagers what the number of teenagers surveyed then that means 200 of them were surveyed because 150 out of 200 is 75%

I don't know the last one because if you had anything there only could get a 100%(im sorry for this one it's a little confusing.

Hope this helps have a great afternoon:)

Answer:

450 - 120 - 80

=250

2/5 × 250 = 100. A

3/5 × 250 = 120 B

Answer:

Grade A   2:9

Grade B   1:3

Grade C  4:15

Step-by-step explanation:

Students in grade A:

[tex]450-(120+80)=450-200=250[/tex]

if the ratio is 2:3 then

[tex]A=(250/5)(2)=(50)(2)=100[/tex] students

The ratio of students with grade A:

[tex]\frac{100}{450}=\frac{10}{45} =\frac{2}{9}[/tex]

= [tex]2:9[/tex]

Students with grade B.

[tex]B=250-100=150[/tex]

The ratio of B:

[tex]\frac{150}{450} =\frac{15}{45} =\frac{1}{3}[/tex]

[tex]= 1:3[/tex]

Ratio of students with grade C:

[tex]=\frac{120}{450} =\frac{12}{45} =\frac{4}{15}[/tex]

[tex]=4:15[/tex]

Answer:

[tex]x=\sqrt{40}, y=\sqrt{104}[/tex]

Step-by-step explanation:

Note the triangle formed by x, y, and 8 is similar to the largest triangle

so x : c = 8 : y = y : 13, where c is the rightmost vertical length, c² = x² + 5²

From 8 : y = y : 13, we get
y² = 13*8 = 104, so

[tex]y=\sqrt{104}[/tex]

From x : c = 8 : y, we have xy = 8c

x²y² = 64c²

104x² = 64(25 + x²)

104x² = 1600 + 64x²

40x² = 1600

x² = 40

[tex]x=\sqrt{40}[/tex]

Answer:

Answer:

what're we ok with me if it's ok to you zoo lights and d and d and how old are you and

(a) True. Suppose A is a not a square matrix, with m rows and n columns. Then A² is not defined, because you can't multiply an m×n matrix by another m×n matrix.

(b) False. As an example, consider the matrices

[tex]A_{3\times2} = \begin{bmatrix}1&0\\0&1\\0&0\end{bmatrix}[/tex]

[tex]B_{2\times3} = \begin{bmatrix}-1&0&1\\0&0&1\end{bmatrix}[/tex]

Then both AB and BA are defined, with

[tex]AB_{3\times3} = \begin{bmatrix}-1&0&1\\0&0&1\\0&0&0\end{bmatrix}[/tex]

[tex]BA_{2\times2} = \begin{bmatrix}-1&0\\0&0\end{bmatrix}[/tex]

In general, you can multiply any m×n by any n×m matrix.

(c) True. Multiplying a m×n matrix by a n×m matrix always yields a m×m matrix, and multiplying a n×m matrix by a m×n matrix always yields a n×n matrix.

Answer:

x=+46

Step-by-step explanation:

2x+4=4x-88

We move all terms to the left:

2x+4-(4x-88)=0

We get rid of parentheses

2x-4x+88+4=0

We add all the numbers together, and all the variables

-2x+92=0

We move all terms containing x to the left, all other terms to the right

-2x=-92

x=-92/-2

x=+46

Answer:

No

Step-by-step explanation:

to change the denomiator from 5 to 30 you have to multiply by 6

if you multiply the denominater by 6, you also have to multiply the numerator by 6

Answer:

Step-by-step explanation:

Let's say :

|1|2|3|4|

|a|b|c|d|

so it would be:

1.b) 2.d) 3.c) 4.a)

[tex]2\sqrt{3x^{2} y}[/tex] = [tex]x\sqrt{12y}[/tex],  [tex]2x\sqrt{6xy^{2} }[/tex] =  [tex]y\sqrt{24x^{3} }[/tex],  [tex]2y\sqrt{2x^{4} }[/tex] =  [tex]x^{2} \sqrt{8y^{2} }[/tex],  [tex]3x^{2} \sqrt{2y^{4} }[/tex] =  [tex]xy\sqrt{18x^{2} y^{2} }[/tex]

An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.

Given expression

(i) [tex]2\sqrt{3x^{2} y}[/tex]

= [tex]2x\sqrt{3y}[/tex]

= [tex]x\sqrt{12y}[/tex]

(ii) [tex]2x\sqrt{6xy^{2} }[/tex]

=  [tex]2xy\sqrt{6x}[/tex]

= [tex]y\sqrt{24x^{3} }[/tex]

(iii) [tex]2y\sqrt{2x^{4} }[/tex]

= [tex]2x^{2} y\sqrt{2}[/tex]

= [tex]x^{2} \sqrt{8y^{2} }[/tex]

(iv) [tex]3x^{2} \sqrt{2y^{4} }[/tex]

= [tex]3x^{2}y^{2} \sqrt{2}[/tex]

= [tex]xy\sqrt{18x^{2} y^{2} }[/tex]

Hence, [tex]2\sqrt{3x^{2} y}[/tex] = [tex]x\sqrt{12y}[/tex],  [tex]2x\sqrt{6xy^{2} }[/tex] =  [tex]y\sqrt{24x^{3} }[/tex],  [tex]2y\sqrt{2x^{4} }[/tex] =  [tex]x^{2} \sqrt{8y^{2} }[/tex],  [tex]3x^{2} \sqrt{2y^{4} }[/tex] =  [tex]xy\sqrt{18x^{2} y^{2} }[/tex]
