Answer: 2t + 10

Step-by-step explanation:

2t represents the number of triangles and 10 bookends the sides of the triangle(s). Notice in the picture each triangle base has a value of two, no matter how many triangles are grouped together. Now notice that no matter how many triangles are grouped together, 5 will always be on the left and right of the final picture.

Answer:

[tex]x^{15/3} =x^{5}[/tex]

Step-by-step explanation:

Answer:

=x⁵

Step-by-step explanation:

It is a rule of indices that [tex]{x^{\frac{a}{b} } }=\sqrt[b]{x^{a} }[/tex]

Therefore:

[tex]\sqrt[3]{x^{15} }[/tex]

= [tex]x^{\frac{15}{3} }[/tex]

=x⁵

Answer:

Haeather ran at a speed of 5 miles per hour.

Step-by-step explanation:

Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:

48/4 = 12

Thus, Haeather ran 1 mile every 12 minutes.

60/12 = 5

1 x 5 = 5

Therefore, Haeather ran at a speed of 5 miles per hour.

Answer:

The scale factor is 1/2

Step-by-step explanation:

If the larger one is the original and one angle is 6 but then it gets dilated to 3. It would be 1/2 because 3 is a half of 6.

Answer:

0.25

Step-by-step explanation:

Answer:

288

Step-by-step explanation:

If you didnt know a triangle has the area of a square/2

so basically what im saying is the area of that square/2 equals the area of the triangle

to find the area of the square you take 24 and square it

24^2=576

finally we divide that by 2

576/2=288

so the area of the triangle is 288

have a great day :D

Answer:

answer is in the picture.

Answer: D

Step-by-step explanation:

Answer:

D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.

Step-by-step explanation:

Got it right on unit test review

The probability of it occurring by chance alone is not unlikely.

We have given that,

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31.

repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random.

The sample was completed in under an hour.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317.

D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.

Answer:

The kite is about 44.1 feet high.

Step-by-step explanation

Since you are trying to find the height, you would draw a triangle to diagram which sides you need to use. The 123 ft of string would be the hypotenuse of the triangle while the 21 degrees is the theta. You are trying to find the height and from the theta that would be the opposite side so you would use sine because you are using opposite and hypotenuse.

sin21=x/123

You have sin of 21 because that is the angle measure, then opposite over hypotenuse which is x/123.

You then multiply both sides by 123 to get the variable of x alone on one side.

123sin21=x

Then just plug this into your calculator and round to the nearest tenth and you get 44.1 feet.

Hope this helped explain how to do these problems, I had trouble doing them awhile back in Algebra 2 so hope this helped out a little.

Answer:

yes

Step-by-step explanation:

if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser

say we did 3.13 as our first number

3.13 - 3.12 = 0.01

this means that 3.13 is greater by 0.01, if we switch the two numbers however...

3.12 - 3.13 = -0.01

then that means that 3.12 is lesser by 0.01

i hope this makes sence, working with decimals may get tricky sometimes lol

Yes, 3.13 is greater than 3.12.

A decimal number is a number in which whole number part is separated from a decimal.

We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.

In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.

Hence 3.13 is greater than 3.12.
