Solve each equation below.
у
a.) 5% + 8 = 53 b.)-bw-12=51 c.) + 12 = -2

Answer:

4a²(a² - 5)​

Step-by-step explanation:

4a⁴ – 20a² =

4a²× a² - 4a²×5 =              ⇒ common factor is 4a²

4a²(a² - 5)​                         ⇒ factorized

Answer:

-4

Step-by-step explanation:

Answer:

A=7

Step-by-step explanation:

2a-6a+24=-4

simplify

-4a+24=-4

subtract 24 from both sides

-4a=-28

divide both sides by -4

a = 28/4

simplify 28/4 to 7

a=7

Answer:

Just multiply with 1000

You get 2961

So 2961

Answer:

x = ± [tex]\frac{6}{11}[/tex]

Step-by-step explanation:

Given

x² = [tex]\frac{36}{121}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{36}{121} }[/tex] = ± [tex]\frac{\sqrt{36} }{\sqrt{121} }[/tex] = ± [tex]\frac{6}{11}[/tex]

Answer: y=4x-2

Step-by-step explanation:

Slope-intercept form: y=ax+b, where a is the slope and b is the y-intercept.

Given: slope is 4, and y-intercept is -3

y=ax+b

y=4x+(-3)

y=4x-3

Hope this helps!! :)

Please let me know if you have any question

Answer:

1.) Yes

2.) Yes

Step-by-step explanation:

Given that

n = k(k + 7)

If k is a positive integer and n = k(k + 7), is n divisible by 6 ?

(1) k is odd. Yes.

Let assume that k = 3

Then, n = 3(3 + 7)

n = 3 × 10

n = 30.

30 is divisible by 6.

(2) When k is divided by 3, the remainder is 2. That is,

Let k = 5

Then,

5/3 = 1 remainder 2

Substitute k into the equation

n = k(k + 7)

n = 5(5 + 7)

n = 5 × 12

n = 60

And 60 is divisible by 6.

Therefore, the answer to both questions is Yes.

25°C

C = 5/9(F - 32)

= 5(77 - 32)/9

= 5×45/9

= 5×5

= 25° C

Answer: The answer is 25°C.

  I hope this helped and please please mark me as brainlest.

=================================================

Explanation:

r = correlation coefficient

If r is close to -1, then the points are close to (or some fall on) the same straight line that has a negative slope. We consider this be a strong negative linear correlation.

If r is close to +1 or just 1, then the points are close to the same straight line that has a positive slope. These points would be considered to have strong positive linear correlation.

By "same straight line", I mean the regression line or line of best fit.

Answer:

20, 40, 60

Step-by-step explanation:

We can find the LCM by making a list which is my favorite way.

Cell phone number 1: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

Cell phone number 2: 5, 10, 15, 20, 25, 30, 35 40, 45, 50, 55, 60

Answer:

The first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.

Step-by-step explanation:

Let the first cell phone be A, that is, A beeps every 4 minutes

and let the other cell phone be B, that is, B beeps every 5 minutes.

Cell phone A will be at the 4th, 8th, 12th, 16th and 20th minutes while cell phone B will beep at the 5th, 10th, 15th and 20th minutes. Hence, the first time the cell phones will beep together is the 20th minute.

Cell phone A will then beep at the 24th, 28th, 32nd, 36th and 40th minutes while cell phone B will beep at the 25th, 30th, 35th and 40th minutes. The second time the cell phones will beep together is the 40th minute.

Cell phone A will beep at the 44th, 48th, 52nd, 56th and 60th minutes while cell phone B will beep at the 45th, 50th, 55th and 60th minutes. The third time the cell phones will beep together is the 60th minute.  

Hence, the first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.

Answer:

0.29 rounded to the nearest ones is 0.

0.29 rounded to the nearest tenths is 0.3

0.29 rounded to the nearest hundredths is 0.29

Step-by-step explanation:

Note that when rounding, you always look at the place value directly next to the one you are rounding. Note that if the digit is 5 or greater, round up; If 4 or less, round down.

Round to the nearest ones:

Look at the place value directly next to the ones (tenths place value). It is a 2. Because 2 is less than 5, round down:

0.29 rounded to the nearest ones is 0.

Round to the nearest tenths:

Look at the place value directly next to the tenths (hundredth place value). It is a 9. Because 9 is greater than 5, round up:

0.29 rounded to the nearest tenths is 0.3

Round to the nearest hundredths:

Look at the place value directly next to the hundredths (thousandths place value). Because there is no number, it is typically signified by a 0 (place holder).

0.29 rounded to the nearest hundredths is 0.29

Answer:

Step-by-step explanation:

So if the delivery person weights 160 lbs than we’re going to subtract 670-160=510 next we divide 40 into 510 which is 12.75. Which means that he can bring 12 boxes.

Answer:

12

Step-by-step explanation:

max cap 670lb- delivery person 160lb  weight left 510lb

weight 510lb/each box 40lb number of boxes 12.75lb

each box 40lb times number of boxes 12lb  480lb+160lb 640lb

so your still have 30 lb before max weight of elevator

Answer: x=16

Step-by-step explanation:

For this problem, we can set a proportion to find the side length of the smaller rectangle.

[tex]\frac{15}{24}=\frac{10}{x}[/tex]                                     [cross multiply]

[tex]15x=240[/tex]                                 [divide both sides by 15]

x=16

Answer:

Answer:

07:43: 12 AM

Step-by-step explanation:

Given that:

Traffic lights change after every 48, 72 and 108 seconds.

They changed simultaneously at 7:00 AM.

To find:

At what time, they will change simultaneously again ?

Solution:

For this, we need to find LCM(Least Common Multiple) of the three numbers and then add it to 7:00 AM to find the time they will change together again.

Because LCM of 3 numbers is the least number which is divisible by all 3 numbers.

Let us factorize the numbers and underline the common part:

[tex]48 = \underline{12}\times 4\\72 = \underline{12}\times 6\\108 = \underline{12}\times 9[/tex]

Common part is taken only once and the remaining part is multiplied to it to find the LCM.

So, LCM = [tex]12 \times 4\times 6 \times 9 = 2592[/tex]

In 2592 seconds, they will change together again.

Changing 2592 seconds in minutes:

Let us divide it by 60:

We get 43 minutes 12 seconds.

Let us add it to 7:00AM, we get the following:

So, the time at which they will change simultaneously = 07:43: 12 AM

Answer:

EA, EB, EC and ED are opposites rays.

Step-by-step explanation:

Given that,

Line AB and line CD intersect at point E.

According to figure,

We need to find opposite rays

Using diagram

We draw a first line AB and second line CD which is intersect of AB at point E.

Now, EA and EB is called opposite ray of first line AB.

Similarly,

EC and ED is called opposite ray of first line CD.

Hence, EA, EB, EC and ED are opposites rays.

Answer:

[tex]\frac{5}{18}[/tex]

Step-by-step explanation:

When dividing fractions, the formula is simple: Keep Flip Change (KFC)

So keep [tex]\frac{1}{4}[/tex] change your division sign to a multiplication sign, and flip [tex]\frac{9}{10}[/tex] so it becomes [tex]\frac{10}{9}[/tex].

[tex]\frac{1}{4}[/tex]·[tex]\frac{10}{9}[/tex]=[tex]\frac{10}{36}[/tex]

Then you need to reduce your fraction to simplest form.

Answer:

25.08

Step-by-step explanation:

-12n - 2 = -303

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, n. Do the opposite of PEMDAS.

First, add 2 to both sides:

-12n - 2 (+2) = -303 (+2)

-12n = -303 + 2

-12n = -301

Next, divide -12 from both sides:

(-12n)/-12 = (-301)/-12

n = -301/-12 = 301/12

n = 25.08 (rounded).
