Answer:
1. 36 days, 2. $8,680
Step-by-step explanation:
1. We know that 12 men can do the work in 72 days, so if you add double the men, it will take half the time. Half of 72 is 36, so our answer is 36 days.
2. If $7,000 is borrowed, that person owes $7,000 so far, but they keep it for 4 years with an annual interest rate of 6%. To solve this, we need to find 6% of 7,000. To do this, we multiply 7,000 by .06. That gets us 420. Now, we multiply 420 by 4. That gets us 1,680. Now, we add 1,680 and 7,000. That gets us 8,680. That means the final amount owed is $8,680.
find the value of x in the figure
Answer:
Option (4)
Step-by-step explanation:
By applying triangle sum theorem in ΔABC,
m∠A + m∠B + m∠C = 180°
80° + 40° + m∠C = 180°
m∠C = 180° - 120°
m∠C = 60°
Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]
m∠DCE = m∠ACB = 60°
Now by applying triangle sum theorem in ΔCDE,
m∠DCE + m∠CED + m∠CED = 180°
60° + 70° + x° = 180°
x = 180 - 130
x = 50°
Therefore, Option (4) will be the answer.

at school, the maximum number of students that can be in a class room is 22. if there are 25 students signed up for the geometry class, how many more students can join the class?
Answer:
At school, the maximum number of students that can be in a class room is 22. There are 25 students signed up for the geometry class.
Therefore, there are (25-22)=3 extra students.
Hence, no more students can join the class.
One solution to a quadratic function, h, is given.
-4 + 7i
Which statement is true?
A. Function h has no other solutions.
B. The other solution to function h is -4 − 7i.
C. The other solution to function h is 4 − 7i.
D. The other solution to function h is 4 + 7i.
The answer isn't A. Function h has no other solutions.
I hope this helps.
Answer:
B. The other solution to function [tex]h[/tex] is [tex]-4-i\,7[/tex].
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form [tex]a\cdot x^{2}+b\cdot x + c[/tex] has solutions of the form:
[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], where both are complex if and only if [tex]\sqrt{b^{2}-4\cdot a \cdot c}< 0[/tex].
Hence, if one solution of the quadratic function is [tex]-4+i\,7[/tex], then the other solution is [tex]-4-i\,7[/tex]. The correct answer is B.
Answer: it’s B

Find the solutions of the quadratic equation -9c² +2 +3 = 0.
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Here, a = -9, b = 2 and c =3
Put the values,
[tex]c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69[/tex]
So, the solution are -0.47 and 0.69.

What is 3/11 of 22/39?
Answer:
0.1538
Step-by-step explanation:
first convert 3/11 into a percentage
3÷11=0.272727272727273
0.272727272727273 × 100
27.272727272727/100
27.272727272727%
≈27.27%
27.27% of 22/39
change 22/39 into a decimal
22÷39=0.5641025641》0.564
27.27% of 0.564
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 27.27% * 0.564
Converting percent to decimal:
p = 27.27%/100 = 0.2727
Y = 0.2727 * 0.564
Y = 0.1538

Write an equation of the line that
passes through (-1,2) with a slope of 4
Step-by-step explanation:
Hey there!
Given;
The points is; (-1 , 2) and slope is 4.
Note: Use one-point formula.
[tex](y - y1) = m(x - x1)[/tex]
~ Put all values.
[tex](y - 2) = 4(x + 1)[/tex]
~ Simplify it.
[tex](y - 2) = 4x + 4[/tex]
[tex]4x - y + 6 = 0[/tex]
Therefore, the required equation is; 4x-y+6=0.

Figure ABCD is transformed to figure A′B′C′D′:
a. Angle D prime A prime B prime.
b. Angle A prime B prime C prime.
c. Angle B prime C prime D prime.
d. Angle C prime D prime A prime.
Answer:
D. <C'D'A'
Step-by-step explanation:
Given that figure ABCD is transformed to figure A′B′C′D′, therefore the angles of ABCD would be congruent to the corresponding angles of A′B′C′D′.
<CDA corresponds to <C'D'A'. Therefore:
<CDA = <C'D'A'
Which graph represents an exponential function?
Answer:
A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.

a math student is standing 40 feet from the base of a water tower. the angle of elevation from her horizontal line of sight is 72 degrees. If her "eye height" is 5 feet, how tall is the water tower? Round to the nearest foot.
9514 1404 393
Answer:
128 ft
Step-by-step explanation:
The height of the tower above eye-height is related to the angle by ...
Tan = Opposite/Adjacent
tan(72°) = (tower height above eye height)/(40 ft)
tower height above eye height = (40 ft)×tan(72°) = 123 ft
Since eye height is 5 ft, the total height of the tower from the ground is ...
tower height = eye height + height above eye height
tower height = 5 ft + 123 ft
tower height = 128 ft
