their ages will be 2:3.Find their present ages. with explanation please

Answer:

we have, 1953125=5⁹, so it cannot be a perfect square. If the last digit of a given number is 5, then the last three digits must be perfect squares, 025 or 225 or 625. Otherwise, that number cannot be a perfect square. And as 125 is not a perfect square, so no number ending with 125 can be a perfect square

Answer:

Larger # is X and smaller is y

X = 16 and y = 6

Step-by-step explanation:

X = 4 + 2y

X + Y = 22

4 + 2y + Y = 22

3y = 18

y = 6

X = 4 + 2(6)

X = 16

Step-by-step explanation:

Answer:

Kevin's is 56/88 or 7/11.   Rick's is 32/88 or 4/11.

Hope this helps!

Step-by-step explanation:

First, you need to figure out total points so 56+32 = 88. Now you can figure out the percentage that Kevin's team scored and the percentage Rick's team scored.

K:   56/88    

56/88 = 0.6363636363636...

So Kevin's percentage of total points is 63.363...%

R:   32/88

32/88 = 0.3636363636...

So Rick's percentage of total points is 36.3636...%

The expression [tex]2.4 \times 7[/tex] can be estimated by [tex]2 \times 7[/tex], so the answer would be roughly 14 here. I'm not sure where you got that '1' from.

Directly below that problem, we have the expression [tex]63.2 \times 0.78[/tex] which can be estimated by computing [tex]63 \times 1[/tex] which simplifies to 63. The '1' is from rounding to the nearest whole number.

Other than that, everything else looks correct on your worksheet.

Answer:

c. 3/4

Step-by-step explanation:

The result is 3/4 = 0.75 = three quarters.

Find the least common denominator or LCM of the two denominators:

LCM of 12 and 3 is 12

For the 1st fraction, since 12 × 1 = 12,

Likewise, for the 2nd fraction, since 3 × 4 = 12,

Add the two like fractions:

1/ 12  +  8 /12  =  1 + 8=  9/ 12

9/12 simplified = 3/4

Answer:

Step-by-step explanation:

no repeating x values

Answer:

Yes, because x is rasied to the power of 3

Step-by-step explanation:

Linear algebra is the branch of mathematics concerning linear equations such as:

{\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}=b,}{\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}=b,}

linear maps such as:

{\displaystyle (x_{1},\ldots ,x_{n})\mapsto a_{1}x_{1}+\cdots +a_{n}x_{n},}{\displaystyle (x_{1},\ldots ,x_{n})\mapsto a_{1}x_{1}+\cdots +a_{n}x_{n},}

and their representations in vector spaces and through matrices.[1][2][3]

Linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such as lines, planes and rotations. Also, functional analysis, a branch of mathematical analysis, may be viewed as the application of linear algebra to spaces of functions.

Linear algebra is also used in most sciences and fields of engineering, because it allows modeling many natural phenomena, and computing efficiently with such models. For nonlinear systems, which cannot be modeled with linear algebra, it is often used for dealing with first-order approximations, using the fact that the differential of a multivariate function at a point is the linear map that best approximates the function near that point.

Answer:

6.666  or 6 2/3   and  9. 333  or 9 1/3

Step-by-step explanation:

5+7 = 12 so 1 part is 1

16/12 = 1.333.. = 1 1/3   1 part is changed when the total is higher

5 x 1  1/3 = 6.666  6 2/3

7 x 1  1/3 = 9. 333  = 9 1/3

Answer:

Step-by-step explanation:

Let A and B stand for the two numbers.

A + B = 16

A/B = 5/7

Rearrange the first and substitute:

A = 16-B

(16-B)/B = 5/7

(16-B) = 5B/7

5B/7 = (16-B)

5B = 7(16-B)

5B = 112 - 7B

12B = 112

B = 9.3333 or 9 1/3

A = (16 - 9.333) or (16 - 9 1/3)

A = 6.6667 or 6 2/3

A + B = 16?

9 1/3 + 6 2/3 = 16  YES

A/B = 5/7 ?

(6 2/3)/(9 1/3) = (20/3)/(28/3) = (20/3)*(3/28)

= (20/28) = 5/7  YES

[tex]1. \frac{13}{15} \times \frac{2}{3} \\ = \frac{26}{45} \\ 2. \frac{4}{5} \times \frac{8}{16} \\ = \frac{4}{5} \times \frac{1}{2} \\ = \frac{2}{5} [/tex]

[tex]3. \frac{4}{24} \times \frac{2}{6} \\ = \frac{1}{6} \times \frac{1}{3} \\ = \frac{1}{18} [/tex]

[tex]4. \frac{1}{2} \times \frac{1}{5} = \frac{1}{10} \\ 5.1 \frac{1}{3} \times 4 \frac{4}{5} \\ = \frac{4}{3} \times \frac{24}{5} \\ = 4 \times \frac{8}{5} \\ = \frac{32}{5} \\ = 6 \frac{2}{5} [/tex]

Answer:

The bottom graph

Step-by-step explanation:

The reason for this is, it is the only graph with the slope of 1/3

You figure this out by starting from the origin and counting up until the next place where the line connects with two lines of the grid, then you count across to that cross point

It's known as counting the rise over run

Answer:

It's the 4th graph, to the bottom right corner.

Step-by-step explanation:

Since x is greater than 2, we are looking at everything shaded to the right of 2. The line is also important, if it's a greater than sign or a less than sign, the line will always be dotted. While a greater than or equal to sign, or a less than or equal to sign will always be solid.

Hopes this makes sense :)

6 (3x + 4) = 42

18x + 24 = 42

18x = 42 - 24

18x = 18

18x / 18 = 18 /18

x = 1

Answer: x = 1

Use the Distributive property:

6(3x+4)=42

18x+24=42

18x=42-24

18x=18

x=1

Hope this helps!

Answer:

y = 2/3x - 7

Step-by-step explanation:

Answer: The vector relies on how the objects of where the magnitude and directions should lay on.

Step-by-step explanation:

So, I’ll help you with these 4 problems. So, for the vector 2/4, it would 2 units up and 4 units to the right. The second would be 5 units down and 6 units to the right. The third one would be 3 units up and 1 unit to the left. The last one would be 10 units downs and 12 units to the left. A simplified way of thinking of this is to just look at the signs of the number and see where the vector’s magnitude and directions would go in that point of view when you visual the graph or count it in your head.
