Omar made $299 for 13 hours of work.
At the same rate, how many hours would he have to work to make $253?
Answer:
The answer is (11 hours)
Step-by-step explanation:
I first divided 299 by 13 hours to find the rate.
I got the dividend of 23.
All you do now is add $23 per hour.
Once you add 11 hours of this rate. You'll get the sum of $253.
Solving for the amount of hours by cross multiplication
money/hours=money/hours
$299/13hours=$253/x hours
[tex]\frac{299}{13} =\frac{253}{x} \\\\23=\frac{253}{x} \\\\23x=253\\\\x=253/23\\\\x=11[/tex]

The perimeter of the triangular park on the right is 16x-6. What is the missing length? The bottom side length is 5x+4 and the right most side is 2x-5
Answer:
[tex](9x-5)\ units[/tex]
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The perimeter of a triangle is the sum of the length of their three sides
so
[tex]P=a+b+c[/tex]
where
a,b,c are the length sides of the triangle
In this problem we have
[tex]P=(16x-6)\ units\\a=(2x-5)\ units\\b=(5x+4)\ units[/tex]
substitute and solve for the missing length
[tex](16x-6)=(2x-5)+(5x+4)+c\\c=(16x-6)-(2x-5)-(5x+4)\\c=(9x-5)\ units[/tex]

Subtract. 1.2 – (–7.8) 6.6 –6.6 9 –9
Option c : 9 is the answer.
Explanation:
The expression is [tex]1.2-(-7.8)[/tex]
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means [tex](-) *(-) = +[/tex]
Thus, the expression can be written as
[tex]1.2+7.8[/tex]
Adding the two numbers, we get,
[tex]1.2+7.8=9[/tex]
Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
I'm solving for x, but I'm not confident with my work. I feel like x should be smaller than the other side (121) but I got a result much larger than it. Can someone help?
You have the ratios set up but you need to cross multiply everything:
(5x + 10) x 11 = 121 x 10
55x + 110 = 1210
Subtract 110 from both sides:
55x = 1100
Divide both sides by 55:
X = 1100 / 55
X = 20

Turn both to percentages. Move the decimal point over two spots to the right, making 2%. Multiply the fraction by 2 to get 2/100. PerCENT. A dollar is 100 cents. The fraction as a percentage is 2%. They are equal.
Yes, 0.02 is greater than [tex]\( \frac{1}{50} \)[/tex].
Explanation:
0.02 can be represented as [tex]\( \frac{2}{100} \)[/tex], which simplifies to [tex]\( \frac{1}{50} \)[/tex].
Since [tex]\( \frac{2}{100} \)[/tex] is greater than [tex]\( \frac{1}{50} \)[/tex], it follows that 0.02 is greater than [tex]\( \frac{1}{50} \)[/tex].
Step-by-step explanation:
1. Convert 0.02 to a fraction: [tex]\( 0.02 = \frac{2}{100} \)[/tex].
2. Compare [tex]\( \frac{2}{100} \)[/tex] with [tex]\( \frac{1}{50} \)[/tex].
3. Simplify [tex]\( \frac{2}{100} \) to \( \frac{1}{50} \)[/tex].
4. Since [tex]\( \frac{1}{50} \)[/tex] is smaller than [tex]\( \frac{1}{50} \)[/tex], we conclude that 0.02 is greater than [tex]\( \frac{1}{50} \)[/tex].

for every 4 cups of red paint,___ cups of blue paint are needed
For every 1 cup of blue paint, [tex]\frac{10}{4}[/tex] cups of red paint are needed
For every 1 cup of red paint, [tex]\frac{4}{10}[/tex] cup of blue paint is needed
For every 4 cups of red paint, [tex]\frac{16}{10}[/tex] cups of blue paint are needed
Solution:
Given that, there are 3 1/3 red cups of paint for every 1 1/3 cups of blue paint
Therefore, ratio is
[tex]Red : blue = 3\frac{1}{3} : 1\frac{1}{3}\\\\Red : blue = \frac{10}{3} : \frac{4}{3}[/tex]
For every 1 cup of blue paint, ___ cups of red paint are neededLet "x" be the cups of red paint needed
Then we get,
[tex]\frac{10}{3} : \frac{4}{3}\\\\x : 1[/tex]
This forms a proportion
[tex]1 \times \frac{10}{3} = \frac{4}{3} \times x\\\\x = \frac{10}{4}[/tex]
Therefore, 10/4 cups of red are needed for 1 cup of blue
For every 1 cup of red paint, ___ cup of blue paint is neededLet "x" be the cups of blue paint needed
Then, we get
[tex]\frac{10}{3} : \frac{4}{3}\\\\1 : x[/tex]
This forms a proportion
[tex]\frac{10}{3} \times x = \frac{4}{3} \times 1\\\\x = \frac{4}{10}[/tex]
Thus, 4/10 cups of blue are needed for 1 cup of red paint
For every 4 cups of red paint,___ cups of blue paint are neededLet "x" be the cups of blue paint needed
Then, we get
[tex]\frac{10}{3} : \frac{4}{3}\\\\4 : x[/tex]
This forms a proportion
[tex]\frac{10}{3} \times x = \frac{4}{3} \times 4\\\\x = \frac{16}{10}[/tex]
Thus 16/10 cups of blue paint are needed for every 4 cups of red paint
The ratio of red paint to blue paint is 5:2. Therefore, for every 1 cup of blue paint, 2.5 cups of red paint are needed, for every 1 cup of red paint, 0.4 cup of blue paint is needed and for every 4 cups of red paint, 1.6 cups of blue paint are needed.
Explanation:The initial statement tells us that the ratio of red paint to blue paint needed is 3 1/3:1 1/3. Converting these mixed numbers into improper fractions, that ratio transforms to 10/3:4/3, which simplifies further to 5:2.
So, if you reduce it down:
For every 1 cup of blue paint, 5/2 or 2.5 cups of red paint are needed.For every 1 cup of red paint, 2/5 or 0.4 cup of blue paint is needed.For every 4 cups of red paint, 4*(2/5) or 1.6 cups of blue paint are needed.Learn more about Ratios here:https://brainly.com/question/32531170

What is the solution to this polynomial equation? x3 + 2x2 - 4x - 8 = 0
Final answer:
The solution to the polynomial equation x³ + 2x² - 4x - 8 = 0 can be found by factoring, which yields the solutions x = -2 and x = 2.
Explanation:
The solution to the polynomial equation x³ + 2x² - 4x - 8 = 0 can be found by factoring, using synthetic division, or by using numerical methods such as graphing or using a calculator. Let's use factoring to find the solution.
We can begin by factoring out the greatest common factor, which is 1:
x³ + 2x² - 4x - 8 = (x + 2)(x² - 4)
We can further factor the quadratic term using the difference of squares:
(x + 2)(x + 2)(x - 2) = 0
So, the solutions to the equation are x = -2 and x = 2.
