Answer:
x = 0.8
Step-by-step explanation:
7 1/4x + x - 2 11/12x + 1 2/3x = 5 3/5
Combine like terms;
- convert the fractions to improper fractions
29/4x + x - 35/12x + 5/3x = 28/5
-Convert to a like denominator
87/12x + x - 35/12x + 20/12x = 28/5
-simplify
84/12x = 28/5
7x=28/5
Divide both sides by 7
x = 4/5
x = 0.8

Step-by-step explanation:
If $18,000 is invested at 9% for 15 years. Find the future value if the interest is compounded semi-annually. Please round the answer to the nearest cent (two decimal places) . Enter only the number without $ sign.
Answer:
$67415.73
Step-by-step explanation:
we know that
FV = P(1+r/n)^nt
where FV = future value
P= Present values =$18000
r= rate of interest =9%
n= year. = 15 year
here , the interest is compounded semi-annually
this means n= 30 , r= 4.5%
plugging the value we have
FV = 18000(1.045)^30= $67415.7264= $67415.73
The three angles of a triangle have
measures of 56°, (2x + 4)º, and xº
What are the measures of the three
angles of the triangle? (TEK 8.8D)
A. 56°, 80°, 44°
B. 56°, 90°, 34°
C. 56°, 84°, 40°
D. 56°, 60°, 64°
Answer:
56°, 84°, 40°
Step-by-step explanation:
The three angles of triangles have measures of 56°, (2x + 4)º, and xº.
We need to find the measures of the three angles of the triangle.
We know that, the sum of angles of triangle is equal to 180º. Using this property we get :
56°+ (2x + 4)º + xº =180º
Solving for x.
60 + 3x = 180
3x = 120
x = 40º
Other angle, = 2x+4
= 2(40)+4
= 80+4
= 84º
So, the measures of the three angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).
What is the volume of a sphere with a diameter of 4 meters? (Use 3.14 for π.) 18.84 m 3 100.48 m 3 33.49 m 3 25.12 m 3
Answer:
Step-by-step explanation:
the formula for Volume of the sphere is
V=4/3 * π*r^3
diameter =4, r=2
V=4/3 * 3.14 * 8=33.49
What is the y-intercept of the line?
It crosses the y axis at 4... it is 4 :)
Answer:
a. (0, 4)
General Formulas and Concepts:
Algebra I
The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
According to the graph, the line crosses the y-axis at y = 4. Therefore, our y-intercept is 4. Writing it in coordinate point would be (0, 4), as definition of the y-int.

what is the solution of sqaure root -4x = 100
Answer:
I’m pretty sure it’s -2500
Step-by-step explanation:
Answer:
I think it would be x = -2500
Step-by-step explanation:
You square both sides to get rid of the square root and get -4x = 10000 then divide 10000 by -4 to get -2500
What is the slope of the line that passes through the points (-3, -9)(−3,−9) and (22, -4) ?(22,−4)? Write your answer in simplest form.
Answer:
1/5
Step-by-step explanation:
Equation: [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Points: (-3, -9) and (22, -4)
[tex]y_{2}[/tex] is the second y point that shows up on the question, basically go by order. So it's -4
[tex]y_{1}[/tex] is -9, because again, in order of which coordinates pop-up first in the question
[tex]x_{2}[/tex] is 22, [tex]x_{1}[/tex] is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] = [tex]y_{2} - y_{1}[/tex] and [tex]x_{2} - x_{1}[/tex], we'll put them back in a fraction later
[tex]y_{2} - y_{1}[/tex] = -4 - (-9) = -4 + 9 = 5
[tex]x_{2} - x_{1}[/tex] = 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5

Matt was babysitting for friend's parents Saturday morning and was paid $10 per
hour for 3 hours. Later that evening, he was babysitting for another couple that paid
him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the
day?
Answer:
Matt was paid an average of $10 per hour of babysitting for the day.
Step-by-step explanation:
He babysat in the morning for 3 hours being paid $10 per hour. He later babysat in the evening for 5 hours being paid $20 per hour. Since he was being paid two different amounts throughout the day, the average would be $10. He was being paid atleast $10 per hour for babysitting because even though he was being paid $20 in the evening, the lowest amount of money that he was paid, was $10 making that the average.

If the radius is 21 cm and the angle at
center of circle is 140° then the length of
the arc is ?
Step-by-step explanation:
Given: Radius , r =21 cm
The angle at the center of the circle, n° =140°
Length of an arc =?
W.K.T Formula, Length of an arc = 2πr( n°÷360°) units
= 2*(22/7)*21*(140°/360°)
= 154/3
= 51.33cm
Answer:
2*(22/7)*21*(140°/360°)
= 154/3
= 51.33cm

Which of the graphs below represents the soltuion set for d - 4 > -3?
Answer:
Answer choice "C".
Step-by-step explanation:
In this question, we have to find the graph that fits the inequality.
First, we need to simplify the inequality.
Solve:
d - 4 > -3
Add 4 to both sides.
d > 1
Now, we can find which graph fits the inequality.
We know that the graph has to start at 1, so we can already eliminate answer choices A, B, and D.
General rule of them is that the direction of the arrow is the opposite direction of the inequality sign.
If the inequality is ">", the arrow on the graph should be pointed rightward (→)
If the inequality is "<", the arrow on the graph should be pointed leftward (←)
Since out inequality sign is ">", the arrow has to be pointing rightward, therefore making answer choice "C" the right answer.
