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:

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]

|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]

Answer:

There are 2.54 centimeters in an inch. There are 63,360 inches in a mile. So, there are 160,934 centimeters in a mile. There are 3600 seconds in an hour.

36 cm/sec is 36 times 3600 cm/hour = 129,600 cm/hour. Therefore, there are 129,600/160,934 miles per hour = 0.80529 mph

Step-by-step explanation:

The speed from centimeters per second to miles per hour will be 0.805 miles per hour.

Unit modification is the process of converting the size of a given amount between different units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.

The speed is given below.

Speed = 36 cm per second

We know that in 1 centimeter, there are 1 / 160934 miles. And in one second, there are 1/3600 hours.

Then convert the speed from centimeters per second to miles per hour. Then we have

Speed = 36 x (1/160934) ÷ (1/3600)

Speed = 36 x 3600 / 160934

Speed = 129600 / 160934

Speed = 0.805 miles per hour

The speed from centimeters per second to miles per hour will be 0.805 miles per hour.

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

To represent this problem we must take into account the data they provide us. Once we see this data, we can infer that the best way to represent it is a bar graph that allows us to compare the data of each project leader with respect to each client.

This graph allows us to draw conclusions about what would be the most efficient way to assign the leaders with the clients. Therefore, the best distribution would be:

Sorry if wrong :,D

(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.
