40% of an angle is the complement of 70°.Find the angle step by step
Answer:
Answer:
72°
Step-by-step explanation:
Start by putting the information you’re given into an equation. The angle measure is 4 times the compliment so it has the measure 4x.
Complementary angles are two angels with a sum of 90°.
So our equation will be 4x + x = 90
Add your like terms to get 5x = 90
Divide 90 by 5 to get x by itself.
X = 18
Since the angle we’re trying to find is 4 times the compliment you’re going to multiply 18 by 4 which will give you your answer of 72°
reciprocal of x is 0.25, reciprocal of y is 10. work out value of xy
Answer:
xy = [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Given the reciprocal of x is 0.25, that is [tex]\frac{1}{4}[/tex] then
x = [tex]\frac{1}{\frac{1}{4} }[/tex] = 4
Given the reciprocal of y is 10 then
y = [tex]\frac{1}{10}[/tex]
xy = 4 × [tex]\frac{1}{10}[/tex] = [tex]\frac{4}{10}[/tex] = [tex]\frac{2}{5}[/tex]
Answer:
2/5=0.4
Step-by-step explanation:
[tex]\frac{1}{x}\\[/tex]=0.25 ==> x=4
[tex]\frac{1}{y}\\[/tex]=10 ==> y=1/10
Now multiply both x and y
xy=4(1/10)=2/5=0.4
Given distance = speed x time How far would someone go if they drove 50 miles per hour for 30 minutes?
Answer:
25 miles
Step-by-step explanation:
We need to convert 30 minutes to hours
30 minutes * 1 hour/ 60 minutes = .5 hours
distance = speed x time
distance = 50 mph * .5 hours
= 25 miles

Which number line represents the solution to the inequality 4x +20 <40
Step-by-step explanation:
The solution of the line x<5
Inequalities are used to represent unequal expressions
The solution to the inequality [tex]4x + 20 < 40[/tex] is [tex]x < 5[/tex]
The inequality is given as:
[tex]4x + 20 < 40[/tex]
Subtract 20 from both sides of the inequalities
[tex]4x < 20[/tex]
Divide both sides of the inequalities by 4
[tex]x < 5[/tex]
This means that the solution to the inequality [tex]4x + 20 < 40[/tex] is [tex]x < 5[/tex]

In ΔABC, if m∠CAD = 29°, the m∠DAB is
Answer:
Angle DAB is 29°.
Step-by-step explanation:
The lines in the two angles show that they are equal.
So angle DAB is equal to angle CAD.
m∠DAB is 29°
Given:
m∠CAD = 29°
From the image given showing ΔABC, the two angles, ∠CAD and ∠DAB are congruent to each other. This is indicated in the diagram with each single stroke on each angle.

If [tex]x=1[/tex], then [tex]y=a\cdot1^2+b\cdot1+c=2[/tex], so [tex]a+b+5=2[/tex] or [tex]a+b=-3[/tex].
If [tex]x=2[/tex], then [tex]y=a\cdot2^2+b\cdot2+c=1[/tex], so [tex]4a+2b+5=1[/tex] or [tex]2a+b=-2[/tex].
We have

[tex](2a+b)+(-a-b)=-2+3[/tex]

The school population for a certain school is predicted to increase by 60 students per year for the next 13 years. If the current enrollment is 900 students, what will the enrollment be after 13 years?
Answer:
1,680
Step-by-step explanation:
If the population is increasing by 60 for the next 13 years, we must multiply 60 and 13 to get 780.
Then, we just add 780 to the original population to get 1,680!
The enrollment after 13 years will be 1680.
We have a whose school population is predicted to increase by 60 students per year for the next 13 years. Current enrollment in that school is 900 students.
We have to determine the enrollment be after 13 years.
Starting from x, if the bacteria count rises by 5 every second, then determine the formula to calculate the bacteria count after 30 seconds.Initial count = x
Count increasing per second = 5
Assume that the bacteria count after t seconds is y. Then -
y = x + 5t
for t = 30 ↔ y = 150 + x
According to question, we have -
Initial population P(i) = 900
Assume the population after the n years is P(n).
Number of students enrolled in 'n' years will be = 60n
Therefore, the following equation can be used -
P(n) = P(i) + 60n
For n = 13 years
P(13) = 900 + 60 x 13 = 900 + 780 = 1680
Hence, the enrollment after 13 years will be 1680.

Mary needed capital for her bakery. She borrowed $60 000 for 4 years at a simple interest rate of 8% per year. How much money will Mary pay at the end of 4 years?
Answer:
$ 79600
Step-by-step explanation:
interest=prt (p is the amount borrowed, r is the rate, t is the time)
p=60000 , r=8%=0.08 , t=4 years
interest=60000*0.08*4
A=19600
the amount paid at the end of 4 years: 60000+19600=$79600
Using the graph of f(x) and g(x), where g(x) = f(k⋅x), determine the value of k.
Answer:
[tex]k=4[/tex]
Step-by-step explanation:
So we have the graphs of f(x) and g(x).
And we know that g(x) is defined as f(kx), where k is some constant.
First, from the graph we can note two points:
For g(x), we have the point (1,10) and for f(x), we have the point (4,10).
In other words:
[tex]g(1)=10[/tex]
And since we know the g(x) is f(kx), this means that:
[tex]g(1)=10\\g(1)=10=f(1(k))=10[/tex]
And we know the for f(x) to be 10, the initial value is 4. Therefore:
[tex]f(1(k))=10=f(4)\\1k=4\\k=4[/tex]
Therefore, the value of k is 4.
Answer:
[tex]\huge \boxed{k=4}[/tex]
Step-by-step explanation:
The graph of g(x) crosses the point (1, 10).
The graph of f(x) crosses the point (4, 10).
So, g(1) = 10. The x (input) is 1. The output is 10.
f(4) = 10. The x (input) is 4. The ouput is 10.
g(1) = f(4)
g(x) = f(k ⋅ x)
g(1) = f(k ⋅ 1)
f(k ⋅ 1) = f(4)
k ⋅ 1 = 4
k = 4

Answer: C.) The total number of stamps is 35.
Step-by-step explanation:
Given the table :
No of 45-cent stamp - - - No of 65-cent stamp
- - - - - - - 18 - - - - - - - - - - - - - - 17
- - - - - - - 20 - - - - - - - - - - - - - - - 15
- - - - - - 22 - - - - - - - - - - - - - - 13
- - - - - - 10 - - - - - - - - - - - - - - - - 25
Verifying each option stated :
Total value of stamp:
Each row add up to 35. Example (18 + 17) = 35
(20 + 15) = 35
(22 + 13) =35
(10 + 25) = 35
Total value of stamp:
Using the first row:
45 cent = $0.45 ; 65 cent = $0.65
(10 * 0.45) + (25 * 0.65)
= $4.5 + $16.25 = $20.75
Not all rows add up to $19.15

What is the perimeter of the parallelogram?
Answer: 36
Step-by-step explanation:
The top and bottom of the parallelogram both have lengths of 8.
To determine the length of the parallel diagonal sides, form a right triangle using the left side of the parallelogram as its hypotenuse (in red in my diagram below).
The right triangle has legs of length 6 and 8, so the length of the hypotenuse (c) is:
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10
Thus the two diagonal sides of the parallelogram must both have a length of 10, so the perimeter of the parallelogram is 8 + 10 + 8 + 10 = 36.
