Step-by-step explanation:

to find the scale factor, divide 10 by 4.

use the answer and divide it by 25 :)

________

10÷4=2.5

25÷2.5=10

The scale factor is 2.5 and the value of x will be 10.

The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making. The scale factor is the ratio of the scaled size to the original size.

Given that one triangle has the sides x and 4 and another has 25 and 10.

The scale factor will be calculated as below:-

Scale factor = 10 / 4

Scale factor = 2.5

Use the answer and divide it by 25. The value of x will be calculated as below:-

x = 25÷2.5

x = 10

Therefore, the scale factor is 2.5 and the value of x will be 10.

Hey there!

[tex]Answer:\boxed{x=\frac{-1}{2}y+17}\boxed{y=-2x+34}[/tex]

[tex]Explanation:[/tex]

[tex]y=-2x+34[/tex]

flip the equation.

[tex]-2x+34=y[/tex]  flip the equation.

Now add -34 to both sides of the equation.

[tex]-2x+34+-34=y+-34\\-2x=y-34[/tex] add -34 to both sides of the equation.

In our third/last step, we will divide both sides of the equation by -2.

[tex]\frac{-2x}{-2}=\frac{y-34}{-2}[/tex] divide both sides of the equation by -2.

[tex]x=\frac{-1}{2}y+17[/tex] The answer to your equation.

There is nothing to solve for y because the equation was equal to y.

Answer:

87

Step-by-step explanation:

We know Heather recieved grades of 80, 75 and 86.

Let's find her average on those 3 tests.

80 + 75 + 86 = 241   Since there are 3 tests we divide by 3.

241/3 = 80.3333   Is her aveerage on the first 3 tests.

She need to average 82 so we can write an equation with t being the score on her 4th test.

[tex]\frac{80 + 75 + 86 + t}{4} = 82[/tex]

[tex]\frac{241 + t}{4} = 82[/tex]         Multiply each side by 4

([tex]\frac{241+t}{4}[/tex]) * 4 = 82 * 4         4 on the left will cancel

241 + t = 328     Subtract 241 from each side

241 - 241 + t = 328 - 241

t = 328 - 241

t = 87

Heather must get an 87 to have an average score of 82.

Answer:

4 players and 1 instructor

Step-by-step explanation:

If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160    200-160 = 40 The club will have $40 left.

Answer:

24a³

Step-by-step explanation:

Simplify, then,  2.1  2³ divided by 2¹= 2 (³_¹)= 2²

( 3 . 4³ .2.   =24a³.

Simplification of an expression is making it as simple as possible. The simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}\\\\^n\sqrt{a} = a^{1/n}\\(ab)^c = a^c \times b^c[/tex]

For the given case, the expression is simplified by using the given rules as:

[tex][3(2a)^{3/2}]^2 = 3^2 \times (2a)^{\dfrac{3}{2} \times 2} = 9 \times (2a)^3\\[/tex]

[tex][3(2a)^{3/2}]^2 = 9 \times 8 \times a^3 = 72a^3[/tex]

Thus, the simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

Answer:

The answer is that it is a rational number because it is a terminating decimal

Step-by-step explanation:

0.62581 is a rational number.

Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers.

Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.

Now the given number is,

0.62581

Now here we see that the numbers after decimal are terminating and non-repeating.

Also the digit after decimal stops.

Hence the number 0.62581 is rational.

Step-by-step explanation:

[tex]\frac{2}{5}-(-\frac{5}{6})[/tex]

Remember, a number minus the negative of a number would be equal to that first number plus that second number but not negative. In other words:

a - (-b) = a + b

So:

[tex]\frac{2}{5}-(-\frac{5}{6})=\frac{2}{5}+\frac{5}{6}[/tex]

The sum of two positive numbers would be a positive number. Because of this, we can see that the value would be positive.

The Point F is at 10.

We have on a number line -  

C → at → -6

D → at → 24

We have to determine the coordinates of F which is [tex]$\frac{1}{3}[/tex]  of the way from C to D.

A Number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

According to the question, we have -

C → at → -6

D → at → 24

Total distance between C to D = |24| + |- 6| = 24 + 6 = 30

The coordinates of point F will be -

[tex]$\frac{1}{3} \times 30 = 10[/tex]

Hence, the Point F is at 10.

Yes your answer is correct.

Yes, you did it correctly.

We have two opposite quantities.

We have to show that opposite quantities combine to make zero.

Any quantity with both magnitude and direction is called vector quantity.

Two vectors are said to be equal and opposite if they have same magnitude and angle of 180 degrees between them.

According to the question -

Assume a number line and mark a number say  'x'  after 0 and a number  

'-x' before zero. These two numbers represent the quantities with same magnitude. And it can be easily seen that the angle between line from center point 'O' to 'x' and the line from 'O' to '- x' is 180 degrees. Hence, these two equal and opposite quantities which will give a resultant value of = + x + (- x) = + x - x = 0

1. Subtract 9m from both sides.

6m-6-9m=9m+15-9m

-3m-6=15

2. Add 6 to both sides

-3m-6+6=15+6

-3m=21

3. Divide both sides by -3

-3m/3=21/-3

m= -7

Step-by-step explanation:

(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)

Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.

We know that (n - 2) + n + (n + 2) = 78,

so 3n = 78, and n = 78/3 = 26.

Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.
