∠C and ∠D are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55. What is m∠D ?
Vertical angles are the same,
Set the two equations to equal each other to solve for x:
5x-7 = 8x-55
Subtract 5x from both sides:
-7 = 3x -55
Add 55 to both sides:
3x = 48
Divide both sides by 3:
x = 48 /3
x = 16
Now you have a value for x, solve angle D:
8x -55 = 8(16) - 55 = 128 - 55 = 73 degrees.
Answer:
The answer is m∠D is 73.
Step-by-step explanation:
In order to determine the answer, we have to know about vertical angles.
Vertical Angles are the angles opposite each other when two lines cross. These angles share the same vertex. I have attached an image that shows vertical angles.
So, according to the definition:
m∠C=m∠D
m∠C=5x-7
m∠D=8x-55
[tex]5x-7=8x-55\\5x-8x=-55+7\\-3x=-48\\x=\frac{-48}{-3}\\ \\x=16[/tex]
m∠D=8*16-55=73
Finally, the angle m∠D is 73.

What is a proportion? Give an example with your description
y = f(x) = -5X
Find f(x) when x = 0.
The value of the function f(x) = -5x when x = 0 is 0. This point also represents the y-intercept of a declining straight line graph.
To find the value of the function f(x) when x equals 0, we simply substitute 0 for x in the given function. The function provided is f(x) = -5x, which implies a linear relationship between y and x. Therefore:
f(0) = -5(0) = 0
The value of f(x) at x = 0 is 0, which also represents the y-intercept of the graph. Since the coefficient of x is negative, we know the graph is a declining straight line. However, at the point where x = 0, the graph will intersect the y-axis.

Yanni threw his paper airplane 15 1/2 feet. Adrian threw his paper airplane 3/4 of yanni's distance. What is the distance Adrian paper airplane? Explain how you found your answer
Answer:
19.125
Step-by-step explanation:
multiply 15.5 by 3 and then divide the answer by 4
Final answer:
To find the distance Adrian's paper airplane traveled, convert Yanni's distance to an improper fraction, calculate 3/4 of that, and then convert back to a mixed number. Adrian's paper airplane flew 11 5/8 feet.
Explanation:
The question asks us to calculate the distance Adrian's paper airplane traveled, given that it is 3/4 of the distance Yanni's airplane traveled, which was 15 1/2 feet. First, we need to convert Yanni's distance to an improper fraction. This gives us 31/2 feet. To find 3/4 of this distance, we multiply 31/2 feet by 3/4:
(31/2) × (3/4) = (31 × 3) / (2 × 4) = 93/8 feet.
Now, we convert the improper fraction back to a mixed number to find the distance. This gives us 11 5/8 feet (since 93 divided by 8 is 11 with a remainder of 5).
Therefore, Adrian's paper airplane traveled a distance of 11 5/8 feet.

A. Howie is wrong because he implied that the answer could be negative. B. The correct answer is x = 3.
When Howie attempted to solve the equation [tex]\(x^3 = 27\)[/tex], he mistakenly concluded that x = -3 was a solution.
However, [tex]\((-3)^3\)[/tex] is equal to -27, not 27. Therefore, -3 is not a valid solution to the equation.
Howie's answer was incorrect because he mistakenly included x = -3 as a solution, which does not satisfy the equation [tex]\(x^3 = 27\).[/tex]
The revised answer should only include the correct solution x = 3. The equation [tex]\(x^3 = 27\)[/tex] has only one real solution, which is:

Matthew invested $3,000 into two accounts. One account paid 3% interest and the other paid 8% interest. He earned 4% interest on the total investment. How much money did he put in each account?
Answer:
Mathew invested $600 and $2400 in each account.
Solution:
From question, the total amount invested by Mathew is $3000. Let p = $3000.
Mathew has invested the total amount $3000 in two accounts. Let us consider the amount invested in first account as ‘P’
So, the amount invested in second account = 3000 – P
Step 1:
Given that Mathew has paid 3% interest in first account .Let us calculate the simple interest [tex](I_1)[/tex] earned in first account for one year,
[tex]\text {simple interest}=\frac{\text {pnr}}{100}[/tex]
Where
p = amount invested in first account
n = number of years
r = rate of interest
hence, by using above equation we get [tex](I_1)[/tex] as,
[tex]I_{1}=\frac{P \times 1 \times 3}{100}[/tex] ----- eqn 1
Step 2:
Mathew has paid 8% interest in second account. Let us calculate the simple interest [tex](I_2)[/tex] earned in second account,
[tex]I_{2} = \frac{(3000-P) \times 1 \times 8}{100} \text { ------ eqn } 2[/tex]
Step 3:
Mathew has earned 4% interest on total investment of $3000. Let us calculate the total simple interest (I)
[tex]I = \frac{3000 \times 1 \times 4}{100} ----- eqn 3[/tex]
Step 4:
Total simple interest = simple interest on first account + simple interest on second account.
Hence we get,
[tex]I = I_1+ I_2 ---- eqn 4[/tex]
By substituting eqn 1 , 2, 3 in eqn 4
[tex]\frac{3000 \times 1 \times 4}{100} = \frac{P \times 1 \times 3}{100} + \frac{(3000-P) \times 1 \times 8}{100}[/tex]
[tex]\frac{12000}{100} = \frac{3 P}{100} + \frac{(24000-8 P)}{100}[/tex]
12000=3P + 24000 - 8P
5P = 12000
P = 2400
Thus, the value of the variable ‘P’ is 2400
Hence, the amount invested in first account = p = 2400
The amount invested in second account = 3000 – p = 3000 – 2400 = 600
Hence, Mathew invested $600 and $2400 in each account.

What is the acute angle?An angle that is measuring much less than ninety degrees is called an acute angle. This perspective is smaller than the proper angle (that is equal to 90 stages). For an instance, ∠30°, ∠forty-five°, ∠60°
What is called right angle?Any shape that could be a rectangular or a rectangle, will have its corners equal to ninety tiers or right angle. A proper attitude is therefore referred to as a ninety-diploma perspective. In geometry, the figure formed through two rays, referred to as the perimeters of the angle, sharing a common endpoint, known as the vertex of the angle is referred to as an attitude.

Answer:
The house increases by $23,580 and he current value of the house is $285,580
Step-by-step explanation:
A house on the market was valued at $262,000. After several years, the value increased by 9%.
The first part of the question is to find by how much the house's value increase in dollars, to calculate this, we will simply find;
9% of $262,000
= [tex]\frac{9}{100}[/tex] × $262 000
= [tex]\frac{2358000}{100}[/tex]
=$23580
Therefore, the house's value increase by $23580
The second part of the question is to fin the current value of the house. Hence;
Current value of the house = $262,000 + $23580=$285,589
Therefore the current value of the house is $285,589

The ratio of girls to boys in the school orchestra is 15 to 10. Which ratio is equivalent to 15 to 10?
The equivalent ratio of girls to boys in the school orchestra is 3 to 2 or 3:2.
Solving equivalent ratios
Equivalent ratios are similar ratios in mathematics, that has different terms but the same solution after being solved. The ratio of two numbers usually compares the size of two numbers together.
To find equivalent ratio of a given number. we need to either multiply or divide the original value.
Here, we are to find the equivalent ratio of girls to boys in the school orchestra is 15 to 10.
Girls to boys = 15: 10
i.e.
[tex]\dfrac{15}{10}[/tex]
In its lowest terms, we can divide both the numerator and the denominator by 5, by doing so we get an equivalent ratio.
[tex]= \dfrac{15 \div 5}{10 \div 5}[/tex]

The temperature in Tampa, Florida is 15 degrees warmer than twice the temperature in Chicago, Illinois. The temperature in Tampa is 75 degrees. Write an equation to determine the temperature in Chicago.
Answer:
75=15+2x
30 degrees in Chicago
Step-by-step explanation:
x will be Chicago's temperature.
75=15+2x
Because 75 is the total temperature in Tampa, and you get that total temperature by adding 15 and 2 times the temperature of Chicago.
Subtract 15 from both sides.
60=2x
Divide 2 from both sides.
30=x
So it's 30 degrees in Chicago.
Answer: [tex]75=2C+15[/tex]
Step-by-step explanation:
Given : The temperature in Tampa, Florida is 15 degrees warmer than twice the temperature in Chicago, Illinois.
Let the temperature in Chicago is denoted as 'C in degrees'.
Since , The temperature in Tampa is 75 degrees.
Then, we have the following equation
[tex]75=2C+15[/tex]
Hence, an equation to determine the temperature in Chicago will be [tex]75=2C+15[/tex]
Without multiplying, tell whether the product 0.644 x 0.25 will be greater than 1 or less than 1? Explain how you know.
Answer:
Less than 1
Step-by-step explanation:
As 0.644 and 0.25 are less than 1, then
[tex]0.644=\frac{1}{p}[/tex]
[tex]0.25=\frac{1}{q}[/tex]
where p and q are greater than 1
then
[tex]0.644\times0.24=\frac{1}{p.q}[/tex]
But p.q is greater than 1, so 1/(p.q) is smaller than 1
Answer:
Less than 1
Step-by-step explanation:
Both the number are less than 1, i.e 0.64 and 0.25.
Hence, the result will always be less than 1 and will be in zeros.
If you write both numbers in fraction, the denominator will be greater than the numerator, hence the resulting fraction will be less than 1.
Hope this helps.
