Betty is three times as old as her son now. In 12 years, Betty's age will be three years less than twice her son's age. How old is Betty's son now?
Answer:
Betty is 27. Her son is 9.
Step-by-step explanation:
We will use b to represent Betty's age. We will use s to represent her son's age.
This year:
b = 3s
In 12 years' time:
b + 12 = 2(s + 12) - 3
b + 12 = 2s + 24 - 3
b + 12 = 2s + 21
b = 2s + 9
We know that b = 3s, so we can substitute this value into our equation.
3s = 2s + 9
s = 9
b = 3 x 9
b = 27

Answer:
D m<A = 49.4 deg
Step-by-step explanation:
Since the lines are perpendicular, the sum of the measures of angles A and B is 90 deg.
m<A + m<B = 90
3x - 7 + 2x + 3 = 90
5x - 4 = 90
5x = 94
x = 18.8
m<A = 3x - 7 = 3(18.8) - 7 = 56.4 - 7 = 49.4
Answer: D m<A = 49.4 deg

Island Bank is advertising a special 1.55% APR for long term CDs. Manny takes out a one-year CD for $40,000. The interest is compounded daily. Find the annual percentage yield for Manny's account to the nearest hundredth of a percent. Fill in the blank 1
Answer: 1.55%
Step-by-step explanation:
p = Principal = $40000
r = Interest rate = 1.55% = 0.0155
n = Number of periods = 365
APY = [1 + (r/n)^n - 1]
= [1 + (0.0155/365)^365 - 1]
= [1 + 0.000042)^365 - 1]
= [1.000042]^365 - 1
= 1.015448 - 1
= 1.55%

30 men repair a road in 56 days by working 6 hours daily. In how many days 45 men will repair the same road by working 7 hours daily?
Step-by-step explanation:
(30 men, 56 days, 6 hours daily)
=> (30 men, 48 days, 7 hours daily)
=> (45 men, 32 days, 7 hours daily)

Taylor earned the following amount each day.
• one dollar of the first day
• three dollars on the second day
• nine dollars on the third day
• twenty-seven dollars on the fourth day
Which function represents Taylor's daily earnings as a function of the number of days, t?
A f(x) = 3+1
B f(x) = 3
f(x) = 3t
D f(x) = 3-1
Answer:
f(t) = 3^(t - 1)Step-by-step explanation:
one dollar of the first day = 3^0three dollars on the second day = 3^1 nine dollars on the third day = 3^2twenty-seven dollars on the fourth day = 3^3Numbers increase 3 times a day, it is an exponential function, powers of 3
The function is going to be:
f(t) = 3^(t - 1)Options are not clear, it seems to be D

Answer:
y= Ix-3I (that says absolute value btw)
Step-by-step explanation:
This is the result of starting with y = |x|, then shifting it three units to the right. Replacing x with x-3 moves the xy axis three units to the left, giving the illusion the V shaped curve moved 3 spots to the right.
We don't shift up or down since the vertex is on the x axis.
We also don't vertically compress or stretch the graph either.
Side note: the vertex for this graph is (3,0) which is the lowest point of the curve.

A new car would cost 400$
If 140$ is 35% of the price of a new car then all we need to do is find how much 1% of that new car is
35%:140$
divide by 35 on each side
1%:4$
If 1% is 4$ then 100% is 400$

Step-by-step explanation:
What type of triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°?
A.) acute scalene triangle
B.) right isosceles triangle
C.) equiangular equilateral triangle
D.) obtuse scalene triangle
Answer:
D.) obtuse scalene triangle
Step-by-step explanation:
acute triangle: 3 acute angles
right triangle: 1 right angle, 2 acute angles
obtuse triangle: 1 obtuse angle, 2 acute angles
scalene triangle: no congruent sides
isosceles triangle: 2 congruent sides
equilateral triangle: 3 congruent sides
The question is:
"What type of triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°?"
That means scalene and obtuse.
Answer: D.) obtuse scalene triangle
The triangle is an obtuse scalene triangle, the correct option is D.
What is a Triangle?A triangle is a polygon with three sides, angles and vertices.
The triangle is classified into various types on the basis of the angle and on the basis of the equality of the length of the sides,
When the measure of all the angles of a triangle is less than 90 degree, it is an acute angle triangle.
When the measure of one of the angle of a triangle is equal to 90 degree, it is a right angled triangle.
When the measure of one of the angle of a triangle is greater than 90 degree, it is called an obtuse angle triangle.
When the measure of all side is different, it is a scalene triangle.
When the two side of a triangle is equal, it is an isosceles triangle.
When all the sides of a triangle is equal, it is an equilateral triangle.
The condition given in the question is triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°, it is an obtuse scalene triangle.

Solve -x > 8 or -x < 4.
{x | -12 < x < -6}
{x | x < -12 or x > -6}
{x | x > -12 or x < -6}
Answer:
-4 < x < -8
Step-by-step explanation:
Given solve -x > 8 or -x < 4.
Solve each inequality first
-x > 8
Divide both sides by -1
-x/-1 > 8/-1
x < -8
Also if -x < 4
Divide both sides by -1
-x/-1 < 4/-1
x > -4
Combine both inequality x < -8 and x > -4
-4 < x < -8
Hence the solution set is -4 < x < -8

At your birthday, 38 of the 24 guests were relatives. How many of the guests were NOT relatives?
Answer:
15 guests were not relative.
Step-by-step explanation:
It is given that,
At your birthday, 3/8 of the 24 guests were relatives.
No of relatives,
[tex]=\dfrac{3}{8}\times 24\\\\=9[/tex]
So, there are 9 relative at the party.
No of guests that are not relative,
= 24 - 9
= 15
Hence, 15 guests were not relative.
how can you tell that the inequality 3x - 1 > 3x +2 has no solution just by looking at the terms in the inequality
Answer:
same variable term on both sides
Step-by-step explanation:
Given
3x - 1 > 3x + 2 ( add 1 to both sides )
3x > 3x + 3 ( subtract 3x from both sides )
0 > - 3 ← not true, thus no solution
Because the variable term was the same on both sides then it is eliminated
