Answer:

Step-by-step explanation:

Given:

ToFind:

Solution:

ATQ,

As we know that,

[tex]\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}[/tex]

[tex]\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}[/tex]

[tex]\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}[/tex]

[tex]\implies\:\:\red{x = \dfrac{5a - b}{5}}[/tex]

Similarly,

[tex]\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]

[tex]\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}[/tex]

[tex]\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}[/tex]

[tex]\implies\:\:\red{y = \dfrac{5a+b}{5}}[/tex]

Hence,

Coordinate of 0 is [tex]\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}[/tex]

Answer:

12/25

Step-by-step explanation:

so he walked 12 days so that would be 12 and there was 25 days of feburary so its 25.

Answer - 12/25

Answer:

They are complementary angles.

Step-by-step explanation:

62° + 28°

= 90°

i love these kind of questions :D

okay so lets write our problem down 1st:

(-3÷2)x-9=27

okay so you take one of your answers lets do A 1st and put is as x like this:

(-3÷2)-24x(-9)=27 now solve:

(think of PEMDAS)

P = perenthesis

E = exponents (which you dont have in this problem)

M = multiply

D = divide

A = add

S = subtract

do perenthesis 1st which would be (-3÷2)

(-1.5)-24x(-9)

now multiply 24x(-9)

(-1.5)-216 = (-214.5) does it equal -24 (which was what you plugged in for x)

no it doesnt so A cant be your answer. now do it for the rest of your answers :D

Answer:

The calories you will consume are 1134 calories

Step-by-step explanation:

Let us solve the problem

∵ A recipe for blueberry muffins states that it yields 12 muffins, with 270

  calories per muffin

→ Find the total calories of the 12 muffins

∴ The total calories of them = 12 × 270

∴ The total calories of them = 3240 calories

∵ You instead decide to make mini-muffins, and the recipe yields 20

   mini-muffins

→ That means the same amount of calories are in 20 mini-muffins, to find

   the calories of each one divide the total amount of calories by 20

∵ The calories per mini-muffin = 3240 ÷ 20

∴ The calories per mini-muffin = 162 calories

∵ You will eat 7 mini-muffins

∴ The calories you consume = 7 × 162

∴ The calories you will consume = 1134 calories

Answer: P = 1/12 = 0.083

Step-by-step explanation:

Out of the 12 girls, there will be only one that is the lead-off batter.

we can assume that this is the first being selected at random, then the probability that you will be the lead-off batter, is equal to the quotient between 1 (the outcome where you are selected) and 12 (the total number of outcomes)

Then the probability is:

P = 1/12 = 0.083

The fact that there will be an arrange of only 9 girls does not affect the probability of you getting the position of the lead-off batter.

Step-by-step explanation:

Answer:

x^3 + 10x^2 + 21x - 12

Step-by-step explanation:

(x + 4)(x^2 + 6x - 3)

you can separate to make it easier for u

x(x^2 + 6x - 3) + 4(x^2 + 6x - 3), this is optional u don't have to do this part

x^3 + 6x^2 - 3x + 4x^2 + 24x - 12

add like terms together

x^3 + 10x^2 + 21x - 12

Answer:

b and d

Step-by-step explanation:

Answer:

B and D are the correct answers.

Step-by-step explanation:

A and C are both wrong because we are not dividing 12 by 13, we are dividing 13 by 12.

B and D are corect because we are dividing 13 by 12, not 12 by 13.

Answer:

228

Step-by-step explanation:

substitute 0 for x

Answer:

you can set up a proportion

16.0/130  = x/2150

by cross multiplying you get

130x = 34400

divide by 130 and get

x-264.62

Answer:

[tex]\frac{4}{7}[/tex]

Step-by-step explanation:

The greatest common factor of 36 and 63 is 9.

Thus, [tex]\frac{36}{63}[/tex] = [tex]\frac{4}{7}[/tex] since (36 ÷ 9 = 4) and (63 ÷ 9 = 7).

Answer:

4/ 7

Step-by-step explanation:

you list the factors of each number  so  factors of 36 are 1 2 3 4 6 9 12 18 36 and factors of 63 are 1 , 3 , 7 , 9 , 21 and 63  as the highest common factor in each number is 9 you do 36 ÷ 9 = 4 which will be the numerator and 63÷ 9 = 7 which will be the denominator so the simplest form of 36/63 is 4/7

Answer:

= 1   1/45

Step-by-step explanation:

3 5/6   /   3 3/4

23 /  15

6       4

23 x 4   =  92

6     15  =   90

=  46

   45

= 1   1/45

The answer is 5. Because all you have to do is just divide -45 by -9.

Answer: 894

Step-by-step explanation:

Answer:

y= -(1/3)x -r

Step-by-step explanation:

a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.

In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.

The problem states the line has the same y-intercept so it has to still be -r.

So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

Answer: 3/7

The slope is the same.

Answer:

-9

Step-by-step explanation:

Answer:

markup price = $2.25

Step-by-step explanation:

markup = 45% of $5

markup = 45/100 x 5

markup = $2.25

selling price = $5 + $2.25

selling price = $ 7.25

Answer:

$2.25
