Number in square root is a number multiplied by itself. For example, 10*10 would give us a square root of 100.
Step-by-step explanation:
1. Square root of 36 = 6
2. Square root of 100 = 10
3. Square root of 81 = 9
4. Square root of 49 = 7

You were playing fetch with your dog and accidentally
threw the toy and it got stuck on the roof of your house.
You leaned the ladder against your house at a 30° angle
of elevation. The foot of the ladder is 7 feet from the foot
of the house. How long is your ladder?
You leaned the ladder against your house at a 30 degrees angle -> This create a right triangle, with a 30 degree angle and your ladder is the hypotenuse.
The foot of the ladder is 7 feet from the foot of your house -> The opposite side = 7 feet
In a right triangle, the side that is opposite to a 30 degree angle = 1/2 of the hypotenuse
Since your ladder is the hypotenuse, and the opposite side is opposite to the 30 degree angle, your ladder is 7 x 2 = 14 ft long.

Answer:
a. geometric sequence
b. an = 5(2)^n-1
c. an+1 = an x 2
Step-by-step explanation:
The sequence: 5, 10, 20, 40,...
a. The sequence is geometric because the sequence has a common ratio of 2, each number is made by multiplying the previous number with the common ratio (2).
b. The explicit formula for this sequence is an = 5(2)^n-1
The explicit formula for a geometric sequence is
an = a1 (r)^n-1
Substituting that with the values we know, we will get
an = 5(2)^n-1
c. The recursive formula for this sequence is an+1 = an x 2
The recursive formula for a geometric sequence is
an+1 = an x r
Substituting for the values we know, we get
an+1 = an x 2

HELP DUE IN 5 mins The company ordered boxes of concrete nails weighing 3.35 kgs each and a box of 2.5 kgs of screws. The eight construction workers each received a box of nails and each worker used 1.23 kgs of concrete nails yesterday. What is the weight of the concrete nails left in each box? If the concrete nails were put together in a big toolbox, how much would the concrete nails weigh?
Answer: See below
Step-by-step explanation:
Weight of concrete nails - weight of concrete nails used = weight of concrete nails left
3.35 – 1.23 = 2.12
Weight of concrete nails left * number of workers = total weight of concrete nails
2.12 x 8 = 16.96
There are 2.12 kgs of concrete nails left in each of the boxes and there are 16.96 kgs of concrete nails altogether

I need HELP ASAP, this is about Pythagorean theorem. HELP ASAP NOWWWW!!!!1111
Answer:
30
Step-by-step explanation:
The Pythagorean Theorem is c2 (c squared) = a2 (a squared) + b2 (b squared).
The side lengths (24 and 18) can be plugged in for a and b. C is the length of the hypotenuse.
24 Squared + 18 Squared= c squared
Use a calculator to help you.
24 squared is 576
18 squared is 324
So, 576+324=c squared
Simplify
900=c squared
Now use the squre root on both sides to get rid of the c squared. (use a calculator)

Junior bought a work truck for $13,000. The value of his truck will depreciate, or decrease, by 15% each year. Which recursive formula models the value of his truck after each year?
The correct recursive formula which models the value of his truck after each year is,
⇒ 13,000 (0.85)ⁿ
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Junior bought a work truck for $13,000.
And, The value of his truck will depreciate, or decrease, by 15% each year.
Hence, We get;
The correct recursive formula which models the value of his truck after each year is,
⇒ 13,000 (1 - 15/100)ⁿ
⇒ 13,000 (1 - 0.15)ⁿ
⇒ 13,000 (0.85)ⁿ
Thus, The correct recursive formula which models the value of his truck after each year is,
⇒ 13,000 (0.85)ⁿ

Two people (A and B) travel from X and Y along different routes. their journeys each take the same amount of time. a’s route is 90 km, B’s route is 60 km. B travels at an average speed of 40 km/h what is a’s average speed
Answer:
a’s average speed is 60km/h
Step-by-step explanation:
x = a’s average speed
60/40 = 90/x
Cross multiplication:
60x = 40x90
60x=3600
Divide both sides by 60
x= 60
Person A's average speed is 60 km/h.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
We can start by using the formula:
Distance = speed x time
Let's denote A's average speed as "S" and the time taken for both A and B as "T".
For person B, we have:
60 = 40 x T
Solving for T, we get:
T = 1.5 hours
Now we can use the same formula for person A:
90 = S x 1.5
Solving for S, we get:
S = 60 km/h
Therefore,
Person A's average speed is 60 km/h.

Answer:
0.365 kg
Step-by-step explanation:
The first I did was turn the 250mg to grams so the conversion factor would be 1 milligram = 0.0001 gram.Divide the 250mg by 1000g to get 0.25g. Multiply 0.25g by 60 to get 15g.Add 15g to the weight of the empty basket, 350g. You should end up with 365g.The question asked for kilograms so divide 365g by 1000.The final answer is 0.365kg.I hope this explains it and helps :)
