I really need your help please ​

Answer:

b

Step-by-step explanation:

Answer:

Y = 2x. it is given

now , 2x + 2y = 30

now putting y = 2x ,. in ( 2x + 2y) = 30

hence ,.2x + 4x = 30

6x = 30

x= 5

now ,y= 2x

y = 10

Answer:

increase

Step-by-step explanation:

11.61 was added to 27

Answer:

[tex]x = 11[/tex]

Step-by-step explanation:

Given

The attached parallelogram

[tex]JW = 17[/tex]

[tex]YW = 3x + 1[/tex]

Required

Find x

JW is the midpoint of YW. So:

[tex]YW = 2 * JW[/tex]

This gives

[tex]3x + 1 = 2 * 17[/tex]

[tex]3x + 1 = 34[/tex]

Subtract 1 from both sides

[tex]3x = 33[/tex]

Divide through by 2

[tex]x = 11[/tex]

Step-by-step explanation:

n = 52

x bar = 122.31

standard deviation sd = 38.75

1. the hypothesis:

null hypothesis

h0: μ ≤ 35

alternative hypothesis

h1: μ > 35

2.

we have been given the sd of the sample but not that of the population. so what we are supposed to use here is the t test and not the z test. the following conditions have to be met.

3.

= [tex]\frac{122.31-35}{38.75/\sqrt{52} }[/tex]

= 87.31/5.37

= 16.26

using the T distribution function in excel, the p value was calculated and found to be approximately equal to 0.

TDIST(16.26, 51, 1)

since p value is very small we reject the null and accept the alternate hypothesis.

4. from the result above the answer to this question is yes

Answer:

you plowed more of the field on day 2 than on day one because minus equals

Step-by-step explanation:

Answer:

1,200 meters.

Step-by-step explanation:

Given that the farmer has a field of 300 meters and he wants to fence it with 4 rounded barbed wire, to determine what is the total length of wire he requires, the following calculation must be performed:

300 x 4 = X

1,200 = X

Thus, the farmer needs 1,200 meters of barbed wire to be able to fence his entire field.

Answer:

$1 for 60

Step-by-step explanation:

60$ is a better deal.

Answer:

9\sqrt{2}

Step-by-step explanation:

this is a 30-60-90 triangle so

the side opposite of 30 is x and the opposite side of 60 is x[tex]\sqrt{2}[/tex]. then the side opposite 90 is 2x.

so if 9=x then a=x\sqrt{2}

9\sqrt{2} is the side length of a

Answer:

Amount = $22000

Step-by-step explanation:

Amount = Principal + Interest

Get the interest

Interest = PRT/100

Interest = 20,000*12*10/12*100

Interest = 200 * 10

Interest = $2000

Amount  = $20,000 + $2000

Amount = $22000

Answer:

Step-by-step explanation:

One of the sides in each part is a variable. For the small triangle, it is x. For the irregular quadulatural, it is y. X is the longest of the 3 sides of the triangle. Y is the longest side of the quadulatural. Does this answer your question?

Answer:

Step-by-step explanation:

the equation for the line is y = 4

Answer:

The third term is 25/3

Explanation:

According to the given proportion,

→ First term : second term : : third term : fourth

→ 6 : 18 : : third term : 25

→ 6/18 = third term/25

→ 6*25/18 = third term [multiplying both sides by 25]

→ 1*25/3 = third term

→ 25/3 = third term.

It would take 31 Months for oil to get the same price as diesel.

Answer:

let no be x

by the question

2x-5=9

2x=9+5

x=14/2=7

the secret no is 7.

Answer:

The answer would be 6º

Step-by-step explanation:

first we know that a straight lin is always 180º

so since we know that the angle outside of the triangle is 110º we can do 180º -110º

then we get the measuerment for angle C :70º

since we dont know the measurements of the other angles but know that a full triangle is equal to 180º we make this equation

2+6x+12x+70=180

then we solve

72+18x=180

-72         -72

18x=108

/18    /18

x=6

then we plug in the x value to find the angle measurement

2+6(6)

2+36

38º

your answer is m<CAB is 38º

Answer:

A. 1,177.58 cm³

Step-by-step explanation:

Volume of hemisphere = ⅔πr³

Radius (r) = 16.51 ÷ 2 = 8.255

π = 3.14

Plug in the values

Volume of the hemisphere-shaped cup = ⅔ × 3.14 × 8.255³

= 1,177.57783 ≈ 1,177.58 cm³

Answer:

6?

Step-by-step explanation:

I guessed dont trust the answer

Answer: I (5 + 2/3) oz - xI ≤ 2/5 oz.

Step-by-step explanation:

If we have a mean M, and a measurement error e, then the absolute value inequality that represents the possible values of x, the variable, is:

IM - xI ≤ e

This means that x can be, at maximum, at a "distance" e from M.

In this case, we know that the mean weight is (5 + 2/3) oz, and the error is +- 2/5 oz, then the absolute value inequality that represents this situation is:

I (5 + 2/3) oz - xI ≤ 2/5 oz.
