You need to factor the radicals into products of radicals, and when factoring you should keep in mind you want to obtain perfect square roots. So √125 = √5*√25 and squareroot 25 has a definite answer of 5, so ∛125=∛5×∛25=5×√5. You want to follow the general pattern of factoring perfect squares to obtain a number outside the radical which can be multiplied by the current coefficient

This is a 30-60-90 triangle.<br> a<br> What is the measure of x?<br> Х<br> 43<br> X=<br> = [ ?
kherson [118]

Answer:

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day!

We can solve this problem in two steps; solving and theory.

I'll go and start off with the theory part!

Theory

We know that in geometry there are many types of triangles that have various different angles. With that, there are a few special triangles that people have made formulas for, one being a 30, 60, and 90 degree triangle.

The theorem states that the hypotenuse is 2x, the side opposite to 60 degrees is x\sqrt{3}, and the bottom is x.

Solving

We can solve this problem in a step, we just need to know what the theorem said and implement it here, since we know the values of the sides of the triangle, we can solve it by finding out the opposite side and applying the theorem rules.

If we look at the graph, we can see that the x part of the side opp. of 60 degrees is 4, that means that x would be double of 4, which is 8.

Therefore your answer would be: x=8

Cheers!

erika estimates that she is 200 to 300 miles away from her destination. if her car travels 25 miles per gallon of gas and each g
DedPeter [7]

Answer:

32$ < x < 48$

Step-by-step explanation:

Erika estimates that her destination is between 200 and 300 miles away.

When we divide 200 with 25 miles we get 200/25 = 8 gallons

When we divide 300 with 25 miles we get 300/25 = 12 gallons

When we multiply 8 · 4 = 32$ we get amount of money for destination

200 miles  x = 32$

When we multiply 12 · 4 = 48$ we get amount of money for destination

300 miles  x = 32$

Since that the estimate destination is between 200 miles and 300 miles

then the best estimate for the amount of money is between

32$ < x < 48$

God with you!!!

Answer:

The first term of the sequence is -120.

Step-by-step explanation:

The formula for the "nth" term of a geometric sequence is shown below:

an = a0*r^(n-1)

Where an is the nth term, r is the ratio and n is the position of the term on the sequence. For this problem we want to find what is the initial term, a0, so we will isolate it in the formula as shown below:

a0*r^(n-1) = an

a0 = an/[r^(n-1)]

We then apply the data given to us

a0 = 31.45728/[-0.8^(7-1)]

a0 = 31.45728/[-0.8^6] =31.45728 /-0.262144= -120

The first term of the sequence is -120.

Elenas bed measures 3‘ x 6‘ on the scale drawing what are the actual measurements of her bed
Sonbull [250]

Using proportions, supposing a scale of 1 inch = 3 feet, the actual measurements of her bed are given by: 9 ft x 18 ft.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations such as multiplication or division, from the relations built in the problem.

One example of application of proportions is for scale problems, as the actual scale and the drawing length are compared to find the actual length of the object drawn.

In the context of this problem, the scale is given by:

1 inch = 3 feet.

The drawn length of the bed is given by:

3 inches x 6 inches.

Hence the actual length is given by:

9 feet x 18 feet.

As:

  • 3 x 3 = 9.
  • 6 x 3 = 18.

<h3>What is the missing information?</h3>

The scale of the drawing is missing, hence we are going to suppose that it is 1 inch = 3 feet.
