me pueden explicar las sumas y restas con punto decimal por favor

Answer:

I think it's J

Step-by-step explanation:

Because the ratio is 5:3:2

There are 150 raisins

And since 2 is one less than 3 my estimate would be subtracting 50 from 150 making there be 100 chocolate chips. Then if the unit is 50, 50 x 5 ( 5 in the ratio) would be 250.

I hope this helps, have a good day.

answer:35 grams

explication: because if he need 350 grams of sugar to make 100 cookies , we have to divide 350 by 100 so it gives 35

The number of grams of sugar would he need to bake 10 cookies will be 35 grams.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

To bake 100 of his favorite cookies, Mr.Wallis needs 350 grams of sugar.

Let x be the amount of sugar for 10 cookies.

The number of grams of sugar would he need to bake 10 cookies will be

x / 10 = 350 / 100

x / 10 = 3.5

x = 35 grams

The number of grams of sugar would he need to bake 10 cookies will be 35 grams.

Answer: 2.5

Step-by-step explanation:

Answer:

2 1/2

Step-by-step explanation:

Do keep change flip. Make 2 an improper fraction by making it 2/1. Change the division symbol to a multiplication symbol. Flip 4/5 to 5/4. The equation you should have is 2/1x5/4.  2x5=10 1x4=4. the fraction you should have is 10/4. 10 divided by 4 =2.5. the fraction you should have now is 2 2/4. Simplify 2 2/4 to 2 1/2.

Answer:

y + 2 = 6(x - 3)

Step-by-step explanation:

Point-Slope Form: y + y₁ = m(x + x₁)

Simply plug in your known variables into the point-slope form to find your equation:

y₁ = 2

x₁ = -3

m = 6

y + 2 = 6(x - 3)

168

Step-by-step explanation:

Answer:

168

Step-by-step explanation:

24*7=168

14*12=168

x₁ = 5

x₂ = - 2

Hi there !

x² - 3x - 10 = 0

x² + 2x - 5x - 10 = 0

x(x + 2) - 5(x + 2) = 0

(x - 5)(x + 2) = 0

x - 5 = 0 => x₁ = 5

x + 2 = 0 => x₂ = - 2

Answer:

b = $4000

Step-by-step explanation:

Let b represent the bonus amount.

Then the bonus, b, less the three deductions, is represented by

b - 0.30b - 0.30b - 025b, and this comes to $600.  Find the value of b.

b - 0.85b = $600, or

0.15b = $600

Then b = $4000

Answer:

f(-9)= -189

Step-by-step explanation:

f(-9)= -3(-9)^2-6(-9)

f(-9)= -3(-9)^2 +54

f(-9)= -3(81) +54

f(-9)= -243 + 54

f(-9)= -189

[tex]f(-9)[/tex]  is [tex]-189[/tex]

What is function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

According to question, we have the function [tex]f(x)=-3x^2-6x[/tex]

We have to find [tex]f(-9)[/tex]

So,  [tex]f(-9)=-3[/tex]×[tex](-9)^{2}[/tex][tex]-6(-9)[/tex]

                [tex]=-243+54[/tex]

                [tex]=-189[/tex]

Hence, we can conclude that   [tex]f(-9)[/tex] is [tex]-189[/tex]

Answer:

4.11

Step-by-step explanation:

Margin of error equals critical value times standard error.

MoE = CV × SE

For 90% confidence and n > 30, the critical value is z = 1.645.

The standard error is SE = σ/√n = 15/√36 = 2.5.

Therefore, the margin of error is:

MoE = (1.645) (2.5)

MoE = 4.11

The margin of error of a 90% confidence interval for the mean IQ score of all students with the disorder is 4.1125 and this can be determined by using the formula of margin of error.

Given :

According to the given data, the confidence is 90% and n > 30, so the critical value is z = 1.645.

Now, to determine the standard error using the below formula:

[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]

[tex]\rm SE = \dfrac{15}{\sqrt{36} }=\dfrac{15}{6}[/tex]

SE = 2.5

Now, the formula of margin of error is given by:

[tex]\rm MOE = z\times SE[/tex]

MOE = (1.645) [tex]\times[/tex] (2.5)

MOE = 4.1125

So, the margin of error is 4.1125.

Step-by-step explanation:

Answer:

Line segments J'K' and M'N' do not intersect and are the same distance apart as JK and MN.

Step-by-step explanation:

If the line segments are translated 2 units to the left, then JK will start at (1, -1) and go to (5, -1), and MN will start at (1, -2) and to to (5, -2).  So the line segments remain parallel and the same distance apart.
