Therefore, - 18 is the answer of the given equation.

Answer:

-18

Step-by-step explanation:

the parentheses mean to multiply, so 9 times 2 is 18, but since it is a negative and a positive that you're multiplying, then it would be negative 18

a line containing the points (4, y) and (-3, 2) has a slope of 3/2.

Answers

Answer:

y=14.5

Step-by-step explanation:

A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.

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

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?

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".

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

To Label or Not to Label: California Prepares to Vote on Genetically Engineered Foodsby Richard Dahl (excerpt)Although campaigns for and against GE labeling [for genetically engineered foods] in California are focusing heavily on economic impacts, the real debate revolves around a scientific question: Are these foods truly safe or not?I think its fair to say that most scientists think the techniques that are used [to create GE plants] are not inherently dangerous, says Peggy Lemaux, a cooperative extension specialist in the Plant and Microbial Biology Department at the University of California, Berkeley. In fact, in 2010 the European Commission released an analysis of 50 studies conducted on GE foods over the last 25 years and concluded that GE technologies posed no greater risks than conventional breeding technologies....The reason I dont worry about GMOs [genetically modified foods] is not because someone has convinced me with a big study that theyre safe, says Michael Eisen, an associate professor of genetics, genomics, and development at the University of California, Berkeley, and an investigator at the Howard Hughes Medical Institute. Its because when I look at the technology, I understand what this technology is doing. Theyre introducing proteins that have been very well characterized into plants, and I dont see any reason at all to suspect that these are harmful. . . .Some scientists, however, believe questions about the safety of GE foods are far from answered. Doug Gurian-Sherman, senior scientist with the Food and Environment Program at the Union of Concerned Scientists, says the question is not whether theres risk involved in GE foods, but whether its greater than risks posed by conventional foods. Because of the greater capacity to bring unknown quantities into the food supply, Im of the school that says it has somewhat higher potential for risk, he says. Other scientists say no. But I dont think its a settled debate.Hansen responds to claims that theres no evidence of harm from GE foods by saying, Thats just not true. I can show you all kinds of studies in the scientific literature that have . . . raised red flags that need to be followed up on. In one such study, investigators reviewed 19 studies of mammals fed GE soybeans and maize. They found that several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects, with the kidneys more affected in males and the liver more affected in females. The authors, noting the limitations of the 28- and 90-day assays they reviewed, pointed out that chronic toxicity testing is not required for GE foods, but that it should be.3Select the correct answer.Which description provides the best objective summary of the article in the passage?A.
