The school administration decided that four grade levels of students (K–3) will share donated funds according to the proportion of students that are in each grade. There are twice as many students in third grade as there are in second grade. There are 5 more students in first grade than there are in second grade. The number of students in kindergarten is 15 more than in first grade. There are 365 students in the K–3 grades at the school.

(A) How many students are in each grade?

(B) What fraction of the money should each grade get?

Answers

Answer 1

Answer:

kindergarten = 88

first = 73

second = 68

third = 88

Step-by-step explanation:

365=k+f+s+t

2s=t

s+5=f

f+15=k

USE SUBSTITUTION

365=((s+5)+15) + (s+5) + s + (2s)

365=5s+25

-25     -25

340=5s

/5      /5

68=s

PLUG IN

t=2(68)=136

f=(68)+5=73

k=(73)+15=88

CHECK

68+136+73+88=365

To get ready for the move you made two trips to the local hardware store. You purchased packages of lightbulbs and packages of batteries so that you would not run out. Each package of lightbulbs was the same. Each package of batteries was the same; however, the price of the lightbulbs is different from the price of the batteries.
On your first trip, you spent $109.78 and purchased 4 packages of lightbulbs and 5 packages of batteries.
On your second trip, you spent $171.72 and purchased 6 packages of lightbulbs and 8 packages of batteries.

What could be shown about the diagonals of parallelogram PQRS to compare the proof that diagonals of a parallelogram bisect each other?

Answers

Answer:

C. PR and SQ have the same midpoing

Step-by-step explanation:

The theorems that could be shown hat the diagonals of parallelogram PQRS bisect each other are explained below.

Let the point where the diagonals intersect be called Point T.

Now, looking at the parallelogram, we can say that;

∠QPT = ∠SRT (This is because the alternate angles between 2 parallel lines are always equal)

Secondly, ∠PQT= ∠RST.

This is This is because the alternate angles between 2 parallel lines are always equal.

Thirdly; ∠PTQ=∠RTS

This is because they are vertically opposite angles.

Now, from AAA congruence theorem, we can say that;

△PTQ is congruent to △RTS.

Thus, we can say that;

PT = RT and QT = ST

This proves that they bisect each other.

How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.

Answers

Answer:

40 minutes

Step-by-step explanation:

What the person above/below me is saying, is you have to divide 360 and 9, to find x! X=40, 360/9=40! That's what they mean. I hope this helped you understand their answer!

It will take 40 minutes for me to make the 360 wraps that I need.

9x ≥ 360 ⇒ x ≥ 40

Step-by-step explanation:

I have to make at least 360 wraps for a party.

I can make 9 wraps per minute.

So, it will take minutes for me to make the 360 wraps that I need.

If I work for x minutes to make wraps, then I will be able to make 9x wraps.

So, the inequality that models the given condition is

9x ≥ 360

⇒ x ≥ 40 {Dividing both sides by 9}

Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

You measure 22 watermelons' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 6.9 ounces. Based on this, construct a 95% confidence interval for the true population mean watermelon weight. Give your answers as decimals, to two places

Answers

Answer:

Step-by-step explanation:

Confidence interval formula is expressed as;

CI = xbar ±(z*s/√n)

xbar is the mean = 36

z is the z score at 95% CI = 1.96

s is the standard deviation = 6.9

n is the sample size = 22

Substitute

CI = 36  ±(1.96*6.9/√22)

CI = 36  ±(1.96*6.9/4.6904)

CI = 36  ±(1.96*1.4711)

CI = 36  ± 2.8833

CI = (36 - 2.8833, 36 + 2.8833)

CI = (33.1167, 38.8833)

Hence the 95% CI for the true population mean is 33.12<x<38.88

Looks like the given curve is

Differentiate both sides with respect to x :

5y + 4z³xz/∂x + z⁴ - 3yz/∂x = 0

Solve for ∂z/∂x :

(4z³x - 3y) ∂z/∂x = - (5y + z⁴)

z/∂x = - (5y + z⁴) / (4z³x - 3y)

We are given the equation:

√(4x - 2) + 3 = 5

Subtracting by 3 on both sides

√(4x - 2) = 2

Squaring both sides

4x - 2 = 4

Adding 2 on both sides

4x = 6

x = 3/2

Step-by-step explanation:

Hey there!

Given;

[tex] \sqrt{4x - 2} + 3 = 5[/tex]

Shift "3" on right side.

[tex] \sqrt{4x - 2} = 5 - 3[/tex]

[tex] \sqrt{4x - 2} = 2[/tex]

Squaring on both sides.

[tex] {( \sqrt{4x - 2} )}^{2} = {2}^{2} [/tex]

Simplify it.

[tex]4x - 2 = 4[/tex]

[tex]4x = 4 + 2[/tex]

[tex]x = \frac{6}{4} [/tex]

[tex]x = \frac{3}{2} [/tex]

Therefore, X = 3/2.
