Whats 4*5+10(2+9) First Person To Answer Gets Brainliest :)

Answer:

1,050 years

Step-by-step explanation:

A comet passes Earth every 70 years.

Another comet passes Earth

every 75 years

If both comets pass Earth this year, how many years

will it be before they both pass Earth on the same year again?

Find the lowest common multiple of 70 years and 75 years

70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,

75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350

Lowest common multiple of 70 years and 75 years is 1,050 years

Therefore,

If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

Answer:

x=10

Step-by-step explanation:

Hope this is helpful! God bless youuu

Add 9 to both sides.

x=1+9

Then, Simplify  1+9  to  10.

x=10

Answer:

This illustrates a right triangle.

Given:

a(height) = 2457 ft.

∠A = 22°23' ; which is the elevation and reflects the a(height)

Find:

b(base)

Solution:

Using the law of cosine, specifically tan∠ = opposite side÷adjacent side

By analysis, tan∠A = a÷b

Since we are finding b, the formula will be derived into:

b = a÷tan∠A

Find b(base):

b = 2457 ft. ÷ tan22°23' ; substituting the numbers

b ≈ 5,966.05 ft. ; Final Answer

Step-by-step explanation:

Answer:

13/15

Step-by-step explanation:

2 1/6= 13/6

2 1/2= 5/2

13/6 divided by 5/2 = 13/6 times 2/5= 26/30

simplify 26/30 = 13/15

Step-by-step explanation:

13/15 it's pretty easy beacause I told my dad a math teacher what's the answer LOL

Answer:

Step-by-step explanation:

Let the cost of one soft taco = s

Let the cost of one burrito  = b

So  we have this system

3s  + 3b  = 11.25  

4s +  2b   = 10.00   (1)

Divide  the first equation through by 3   and we have that

s +  b  =  3.75         subtract  b from both sides

s   =  3.75 - b   (2)

Sub  (2) into (1)  and we have

4 (3.75 - b)  +  2b  =  10.00      simplify

15 - 4b  + 2b   = 10.00

-2b + 15  =10.00      subtract 15 from both sides

-2b  =  - 5.00         divide both sides by -2

b  = 2.50

And using (2)

s  =  3.75 - 2.50   =   1.50

So...  a soft taco  1.50 and a burrito is  2.50

Step-by-step explanation:

The way to solve the problem would be just add the two number as 11+4 =15.

This would avoid the tedious process first drawing the number line and then counting each number to reach the same answer, which could be easily reached by just adding the two numbers.

Answer:

150 miles

Step-by-step explanation:

Let

x = number of miles

Plan A: 0.60x

Plan B: 75 + 0.10x

How many miles would Susan need to drive for the two plans to cost the same?

0.60x =75 + 0.10x

0.60x - 0.10x = 75

0.50x =75

x = 75/0.50

x = 150 miles

Susan needs to drive for 150 miles for the two plans to cost the same

Answer:

2144.66 cubic inches

Step-by-step explanation:

The fishbowl is shaped like a sphere the fishbowl has a diameter of 16.

What is the closest value of water in the Fishbowl in cubic inches?

From the any question, we were told to find the closest value of the water in the fishbowl in cubic inches.

This means we are to find the volume.

The volume of a sphere is given as:

4/3πr³

We are given Diameter of the fish bowl = 16 inches

Radius = Diameter/2 = 16 inches/2

= 8 inches

Hence,

Volume of the sphere (Volume of water) = 4/3 × π × 8³

= 2144.66 cubic inches

Answer:

He missed 3 questions (which is a score of 22/25 that equals 88%)

Step-by-step explanation:

This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.

So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.

Hope it helps.

Answer:

2 pairs of opposite parallel sides is parallelogram

Answer:

I think its 5.6%

if its multiple choice that would help but that's my best guess

Answer:

Step-by-step explanation:

2y + 14.6m + 3.8 - 34.8m - 15.6 -2y

-20.2m -11.8

Answer:

33,398

Step-by-step explanation:

So first you have to do 750x42 and that gets you 31,500 but then you have to pay the down payment so then it is 31,500+1,898 which gets you 33,398.

"The number of boys is 45 the number of girls,"

or to say,

"The ratio of the number of boys to the number of girls is 45:1."

This second interpretation reflects the fact that 45 is the unit rate (which is a number) for the ratio 4:5.

Answer:

Option A wilk be the correct answer.

Answer:

a. acute, equilateral

Step-by-step explanation:

From the picture the lines on the triangle mean that the sides are equivalent to one another so from that you can eliminate option c. There are not right angles within the triangle so you can eliminate option b. The angles are less than 90 degrees as they arent even cloe to being a right angle so they arent obtuse so you can eliminate option d. Now you are only left with option a.
