is 5(1/5^3) = 5(5^3)

Answers

Answer:

5(1/5^3) ≠ 5(5^3)

Step-by-step explanation:

5(1/5^3) = 5(5^3)

5/27 = 625

5(1/5^3) ≠ 5(5^3)

The sides aren't equal, so this equation is FALSE.

Answer:

Step-by-step explanation:

Short answer: No they are not the same.

5 * 1/5^3 = 1/5^2. One of the 5s in the denominator cancels out.

5^1 * 5^3 = 5^(1 + 3) = 5^4. Nothing cancels here. The powers add.

Hooke’s Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?

Answers

Answer:

7.5m

Step-by-step explanation:

Set up a proportion and cross multiply to find the unknown

Hope this helps

The elongation of spring by 170 newtons force maintaining the given ratio is 7.5 cm.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given question,

Elongation of spring in 180 newtons = 5 cm

The ratio of elongation to force applied = 5/180

The force the second time is 270 newtons.

Let's say the elongation at this time is x cm.

The ratio of elongation to force applied = x/270

Both ratios must be the same.

Therefore,  x/270 = 5/180

x = 270/36 = 7.5 cm

Hence "The elongation of spring by 170 newtons force maintaining the given ratio is 7.5 cm".

Answer:34,587

Step-by-step explanation:

A cyclist rides her bike at a rate of 30 miles per hour. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 5 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

Answers

Answer:

48240

Step-by-step explanation:

Part one

1 mile per hour = 1.60 kilometers per hour

30 miles per hour = ?

Step 1: Set up a fraction.

The units must be on the same level. And the rate in KM (kilometer) per hour will be a variable, "[tex]k[/tex]". It does not matter whether they are top or bottom.

[tex]\frac{1.60}{1} = \frac{k}{30}[/tex]

As you can see, 1 mile per hour and 30 miles per hour are at the same level, leaving the rest on the same level, as well.

Step 2: Solve

[tex]\frac{1.60}{1} = \frac{k}{30}[/tex]

Cross multiply

1.60 × 30 = 48

1 × k = 1

Therefore, the rate is 48 kilometers per hour.

Part 2

This part is mainly the same as the first part. Fractions. However, since we've already found out the answer for part one, it will be simple.

Step 1: Multiply the result to 5.

48 × 5 = 240

Therefore, the cyclist will travel 240 kilometers in 5 hours.

240km

Step-by-step explanation:

First, to make everything more clear, rewrite it like this-

1 mile = 1.6km

So we have to multiply 30 (miles) by 1.6 (km)

30 x 1.6 + 48

So it is 48km per hour, now we have to calculate how many km does she ride in 5 hours.

We have to multiply 48 by 5 which equals 240

So the answer is 240km

What is the answer for x?

Answers

The value of x is 5 by using external angle

Answer:

Step-by-step explanation:

The triangle’s angles add up to 180 degrees

so 40 + (16x + 2) + ∠C = 180

The straight angle is 180°

so ∠C = 180 - (23x + 7)  

∠C = 180 - 23x -7

∠C = 173 - 23x

and then 40 + (16x + 2) +(173 - 23x) = 180

40 + 16x + 2 + 173 - 23x = 180

215 - 7x = 180

-7x = 180 - 215

-7x = -35

x = 5

what is the answer? ​

Answers

Answer:

(write this in the format your curriculum suggests, most are different)

Since BC is longer than AB, this means m<bcd is smaller than m<bad.

A way to prove it mathematically is to look at the triangle on the left. Since It's an isosceles triangle, m<cda and m<dac are equal. However, the triangle on the right does not have two proven congruent sides. All we know is BC is larger than the other side lengths. In a figure like that, the obtuse angle that meets the longest side would be the largest angle.

56 = 3x+9
Subtracting on both sides,
56-9 = 3x+9-9
47 = 3x
Dividing on both sides,
47/3 = 3x/3
