what is -9/10 • -2/3 ?

Answers

Answer 1

Multiplying two fractions together corresponds to multiplying together their components, so multiplying -9/10 · -2/3 looks like:

[tex] \frac{-9}{10} \cdot \frac{-2}{3}= \frac{(-9)(-2)}{(10)(3)} [/tex]

If we rearrange the fractions, we can perform some simplification:

[tex] \frac{(-9)(-2)}{(3)(10)} = \frac{-9}{3} \cdot \frac{-2}{10} =-3\cdot \frac{-1}{5} [/tex]

When gets us:

[tex] \frac{(-3)(-1)}{5}= \frac{3}{5} [/tex]

The sum of the measures of two angles is 180°.
One angle measures 3a and the other angle measures 2a - 25 Find a. Then find the measure of each angle.

Answers

A should be here :https://brainly.com/question/2121320

so first make an equation

180 = 3a + 2a - 25
combine like terms
180 = 5a - 25
add 25 to both sides
205 = 5a
divide both sides by 5
41 = a

now substitute 41 into the two angles
3(41) = 123
2(41) - 25 = 82 - 25 = 57

so one angle is 123 degrees
the other angle is 57 degrees

to check it, just add 123 + 57 = 180
yep! its correct

how do you know on a right triangle which leg is a or b (Pythagorean Theorem)

Answers

The real answer is: it doesn’t matter! a and b are just labels we give to the legs; it doesn’t matter how you pick them, especially since addition is *commutative* (order doesn’t matter). An equality valid way of writing the equation would be:

(leg 1)^2 + (leg 2)^2 = (hypotenuse)^2

But it saves time to just write it as a^2 + b^2 = c^2, where a and b are the lengths of the legs and c is the length of the hypotenuse.

How many solutions does this equation have? 7v = 7v + 10

Answers

7v = 7v + 10

Subtract 7v from both sides.

0 = 10

Since 0 = 10 is a false statement this equation has no solution.

How many solutions does this equation have?
Answer: none.

So your variable is v. Let's solve for v.

7v = 7v + 10. subtract 7v from both sides
0 = 10

NO SOLUTION

As you can see, 0 does not in fact equal 10.

Anytime you get a false equation like this which usually results when the variable disappears like it did here, there is no solution.

A truck can be rented from Company A for $120 a day plus $0.50 per mile. Company B charges $30 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

120 + 0.5x = 30 + 0.8x

90 = 0.3x

x = 300

The charges of both companies will be same if truck is driven 300 miles per day.

It is required to find the number of miles in a day.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

Let the truck is driven X miles per day

Charges of company A will be = $120 + $0.50x

Charges of company B will be = $30 + $0.80

Let us find out value of X when charges of both companies are same

Now the following equation should be made

$120 + $0.50x = $30 + $0.80

$120 - $30 = $0.80x - $0.50x

$90 = $0.30x

x = 300 miles.

Therefore, the charges of both companies will be same if truck is driven 300 miles per day.

how much larger is the LCM than the gcf of 18 and 27?

Explain for points

Answers

To start, to answer this question you would first need to find the LCM and the GCF of the numbers, 18 and 27.

The least common multiple, or LCM of 18 and 27 would be 54, in which you find by listing the multiples of both numbers to find the multiple that occurs first and matches with both numbers: 18, 36, 54 27, 54

Now, you have to find the GCF, or the greatest common factor, which is the greatest factor of both numbers that you can take out from both numbers without needing to simplify further. This number would be 9. One way to do this would be listing the factors of both numbers.
18: 1 and 18, 2 and 9, 3 and 6
27: 1 and 27, 3 and 9

Now, to answer the question, you find the difference of the LCM and the GCF. This would be 54-9 which is 45.

Answer: 45

when 18 is subtracted from six times a certain number,the result is -42. what is the number?

Answers

Let x be the number.

Then;

6x-18=-42 (solve for x now)
6x=-42+18
6x=-24
x=-4

Therefore, this number would be -4.

Hope I helped :)

To start off, you want to create an equation. 18 subtracted six times from a certain number (let's use a variable 'x') would look like: 6x - 18.
6x - 18 = -42

Next, isolate the variable by adding 18 to both sides.
6x - 18 = -42
+ 18 + 18
6x = -24

Lastly, solve for x.
6x/6 = -24/6
x = -4

Answers

The answer is C. because 1.5 is the height while x is next to it to show the multiplication of years to height

it grows 1.5 feet per year so multiply that by number of years (x)

1.5x

so you would have 1.5x +2 ≥14

Answer is C. 1.5x + 2 ≥ 14

Eight times 8 1/2 inches comes out to 8(8 1/2 inches) = 8(17/2) = 68 inches.

Answer: The length of row of bricks is 68 inches.

Step-by-step explanation:

Since we have given that

Number of bricks = 8

Length of bricks = [tex]8\dfrac{1}{2}=\dfrac{17}{2}[/tex]

So, Length of the row of bricks is given by

Number of bricks × length of brick

[tex]8\times \dfrac{17}{2}\\\\=4\times 17\\\\=68\ inches[/tex]

Hence, the length of row of bricks is 68 inches.

a lawn mower uses a mixture of gas and oil. for each ounce of oil the mixture contains 10 ounces of gasoline. if the tank holds 99 ounces of the mixture , how many ounces each of oil and gasoline are required to fill the tank completely?

Answers

Final answer:

To fill a 99-ounce tank with a 1:10 oil to gasoline ratio, you need 9 ounces of oil and 90 ounces of gasoline.

Explanation:

A lawn mower uses a mixture of gas and oil, with a ratio of 10 ounces of gasoline to every 1 ounce of oil. To find out how many ounces of oil and gasoline are required to fill a 99-ounce tank, we set up a proportion.

Let's denote the amount of oil needed as x ounces. Since the ratio is 1:10, then the amount of gasoline needed will be 10x ounces. The sum of oil and gasoline should equal the tank's capacity:

x ounces (oil) + 10x ounces (gasoline) = 99 ounces (total mixture)

Combining like terms gives us:

11x = 99

Dividing both sides by 11 yields:

x = 9

Therefore, there would be 9 ounces of oil and 90 ounces of gasoline (since 10 * 9 = 90) required to fill the 99-ounce tank completely.

Final answer:

A 99-ounce tank requires 9 ounces of oil and 90 ounces of gasoline to be filled completely, keeping the ratio of 1 ounce of oil to 10 ounces of gasoline.

Explanation:

The question is about determining the correct ratio of oil to gasoline needed to fill a lawn mower's tank, which holds a mixture of the two. Specifically, for every ounce of oil, the mixture requires 10 ounces of gasoline. To find out how many ounces of oil and gasoline are needed for a 99-ounce tank, we can set up a simple proportion. Let's denote the amount of oil as 'o' in ounces, and since for each ounce of oil we need 10 ounces of gasoline, we thus need '10o' ounces of gasoline.

The total mixture is given as 99 ounces, which is the sum of oil and gasoline, so we have the equation: o + 10o = 99.Solving for 'o' gives us o = 9. This represents the ounces of oil needed.To find the amount of gasoline, we multiply the amount of oil by 10, giving us 10*9 = 90 ounces of gasoline.

Therefore, to fill a 99-ounce tank, we would need 9 ounces of oil and 90 ounces of gasoline.

In mathematics, multiples are the results of multiplying an integer by a given number.

Manifold is the fundamental definition of multiplicity. A multiple in mathematics refers to the outcome of multiplying two numbers together.

For example, multiples of 5 are: 10, 15, 20, 25, 30…etc. Multiples of 7 are: 14, 21, 28, 35, 42, 49…etc.

Given:

A spider has 8 legs.

An ant has 6 legs.

So, multiples of 8= 8, 16, 24, 32, 40, 48

and, multiples of 6= 6, 12, 18, 24, 30, 36, 42, 48

So, least number of spiders because= 8 x 6= 48

and, least number of ants = 6 x 8 = 48

Augmentation is an activity that addresses the fundamental thought of rehashed expansion of a similar number. The numbers that are multiplied are referred to as the factors, and the result that is produced when two or more numbers are multiplied together is referred to as the product of those numbers. Repeated addition of the same number can be made easier by using multiplication.

Given Ferris wheel can accommodate 54 people in 24 minutes

number of people can ride in 1 minute = 54/24

number of minute in 2 hours is 2 x 60 = 120 minutes
