A. y=x+1
B. y=-x
C. y=4x
D.y=x+4

Answer:

x=3

Step-by-step explanation:

Answer:

la respuesta es x=3

Step-by-step explanation:

2x−8+7x=19

2x+−8+7x=19

(2x+7x)+(−8)=19

9x+−8=19

9x−8=19

9x−8+8=19+8

9x=27

Step 3: Divide both sides by 9.

9x9=279

x=3

Answer:

375.2887 ft is the answer

Answer:

375.3 ft

Step-by-step explanation:

What we need to do first is divide 175 by the sine of 25°.

175/sin(25°)

175/0.422618

175/1 * 500000/211309

25/1 * 500000/30187

12500000/30187

414.085534 = length of hypotenuse.

Now, find the square root of the difference between c² & a².

b = √414.09² - 175²

b = √171470.528 - 30625

b = √140845.528

b = 375.293922

b ≈ 375.3

The horizontal distance between the technician and the base of the telephone pole is 375.3 ft.

Answer: rate of interest (r) = 6.25

Step-by-step explanation:

Simple interest formula is S.I = PxTxR/100

From the question ;

S.I = (3/8) principal

3/8p = px6xr/100

Eliminate p on both sides of the equation

r = (3x100) / (8 x 6)

r = 300 / 48

r = 6.25

Answer: 3x-5

Step-by-step explanation:

9x-5(-6x)

9x-5-6x

3x-5

Answer:

15x - 5

Step-by-step explanation:

We have the equation 9x - 5 - (-6x) and are asked to solve it.

We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :

9x - 5 - (-6x)

Two negatives make a positive, therefore :

9x - 5 + 6x

Since 9x and 6x have the same variable ending, we can combine them, do as followed :

9x - 5 + 6x

9x + 6x

15x - 5

Answer:

About 16 days.

Step-by-step explanation:

The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

Step-by-step explanation:

X - 1 is greater than or equal to 6

+1. +1

x is greater than or equal to 7.

7 can work as

7 - 1 is greater than or equal to 6

6 is greater than or equal to 6

10 also works because if you put it in the equation the answer is still more than 6.

Answer:

Step-by-step explanation:

Well you have to solve for X to find Y simplified.

Since both equations equal Y you can plug them together

3x+3=x-1

-x          -x

2x+3=-1

-3         -3

2x=-4

Divide -4 by 2 and you get X = -2 then plug X into both equations and boom

Answer:

volume of a cone = [tex]\pi[/tex] [tex]r^{2}[/tex] h/3

                          [tex]\pi[/tex]  = 22/7 or 3.14

              r (radius) = 8 ft

             h (height) = 16 ft

∴ volume = 22/7 * 8 * 8 * 16/3

                =  3.14 * 64 * 16/3

                = 1072.76190476 [tex]ft^{3}[/tex]

hope this answer helps you.....

please mark as brainliest ..... thank you....

Answer:

1072 ft³

Step-by-step explanation:

Formula we use,

→ V = πr²(h/3)

Now the volume of cone is,

→ πr²(h/3)

→ 3.14 × (8)² × (16/3)

→ 3.14 × 64 × 5.333

→ 200.96 × 5.333

→ 1072.33

→ ≈ 1072 ft³

Hence, volume is 1072 ft³.

Answer: 48 ft

Step-by-step explanation:

Given

Height of street light h=12 ft

length of shadow x=18 ft

Shadow length of building x'=72 ft

suppose the height of the building is y

from the figure, we can write

[tex]\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft[/tex]

Answer:

A

Step-by-step explanation:

Answer:

Step-by-step explanation:

24n + 32w = (3n + w)

We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.

Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that

24n + 32w = 8(3n + 4w)

Answer:

y = 4

Step-by-step explanation:

(2/3 + 4) + (-3/2y + 1/3y) = 0

(-3/2y + 1/3y) = -4 2/3

-9/6y + 2/6y = -14/3

-7/6y = -14/3

cross-multiply:

-21y = -84

y = 4

Answer:

y = 4

Step-by-step explanation:

Please use parentheses for clarity, remembering what big differences they make in expression values.

I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0​" actually means

2/3 - (3/2)y + (1/3)y + 4 = 0​

The LCD here is 6, which is the product of the denominators 2 and 3.

Then your "2/3 - 3/2y + 1/3y + 4 = 0​" becomes:

                     4  - 9y    + 2y + 24 = 0, which simplifies to:

                     28 - 7y = 0.  Solving this, we get y = 4

Answer:

Orange

Step-by-step explanation:

just took the test

The color which contributes most to the chi-square test statistic for the bag of candy is orange color.

Chi-square test is the statistical test, which is used to examine, the difference between the expected frequency and the observed frequency.

[tex]x^2=\dfrac{(o_i-E_i)^2}{E_i}[/tex]

A bag of candy contains 5 different types of colored candies; red, green, blue, yellow, and orange. Students in a statistics class decided to use a chi-square procedure to test the manufacturer’s claim.

They opened a bag of candy and recorded the number of candies of each color.  The results are shown in the following table-

Red  Green  Blue  Yellow  Orange

 17      24       20       25         14

The average of the all the values is 20.

Now, according to the manufacturer, bags should contain an equal number of each color. Thus, the expected value for the bag of candy are,

Red  Green  Blue  Yellow  Orange

 20     20       20       20         20

Form, the above formula the color which has less values of observed, and more value of expected, contributes most to the chi-square test statistic.  

Here, the orange color has the less value of observed frequency. Therefore, the color which contributes most to the chi-square test statistic for the bag of candy is orange color.
