Answer:
1990
Step-by-step explanation:
Since the mother was 50 years old in 2000, she was 50 - (2000-1974) = 50 - 26 = 24 years old in 1974.
Hence, the daughter was 24/6 = 4 years old in 1974.
In "x" years after 1974, the daughter will be 4+x years old, while the mother will be 24+x years old.
We need to find "x" from the equation
2(4 + x) = 24+x.
8 + 2x = 24 + x,
x = 24 - 8 = 16.
1974 + 16 = 1990.
Answer In 1990 the mother doubles her daughter's age
Check In 1990 mother's age is/was 24 + 16 = 40 years.
In 1990 the daughter's age is/was 4 + 16 = 20 years.

In a bag full of small marbles, 1/4 of the marbles are green 1/8 of the marbles are blue and 1/12 of the marbles are
yellow The remaining 26 marbles are white How many marbles are blue?
blue marbles
Step-by-step explanation:
white=26
1/4+1/8+1/12=6/24+3/24+2/24=11/24=(green,blue and yellow marbles)
24-11=13/24=white
26/13=2=1/24
blue=3/24

Write equation of the line with the given slope and Y intercept.
Slope = 1/2.
Y-intercept = 7.
Answer:
y = 1/2x + 7
Step-by-step explanation:
The equation is y = mx + b where m is the slope and b is the y-intercept. So you simply plug in 1/2 for m and 7 for b and you get y = 1/2 +7

A 17-ft ladder leans against a building so that the angle between the ground and the ladder is 71°. How high does the ladder reach on the building? (Round your answer to the nearest foot.)
Answer:
there is 16.08 foot high does the ladder reach on the building
Step-by-step explanation:
The computation of the high does the ladder reach on the building is shown below:
Given that
length of the ladder = 17 ft
angle -between the ground and the ladder = 75 degrees
Based on the above information
Here we used the trig-ratio to calculate the same
[tex]Sin \theta = \frac{oppo}{hyp} \\\\Sin 71^{\circ} = \frac{h}{17}[/tex]
0.946 × 17 = h
The height is 16.08 foot
Hence, there is 16.08 foot high does the ladder reach on the building
∣x−10015∣∣≤23
where x is a person’s IQ. Solve the inequality to find the IQ scores for the middle 50% of the population.
Answer:
9992≤x 10038Step-by-step explanation:
Given the expression
∣x−10015∣∣≤23, we are to find the range of values of x
since the function is in a modulus sign, it can be expressed as a negative and positive function.
If the function is positive;
x - 10015 ≤23
x ≤23 + 10015
x ≤ 10038
If the function is negative;
-(x-10015)≤23
-x+10015≤23
-x≤23-10015
-x≤-9992
multiply through by -1
x ≥ 9992 (note the inequality sign change)
9992≤x
Combine both inequalities
9992≤x and x ≤ 10038
On combining;
9992≤x 10038
Hence the inequality to find the IQ scores for the middle 50% of the population is expressed as 9992≤x 10038
We want to solve an inequality to find the range of IQ scores for half of the population.
We will find that the range is:
77.15 ≤ x ≤ 123.15
The inequality we need to solve is:
|x - 100.15| ≤ 23
To solve it, we write two inequalities.
x - 100.15 ≤ 23
x - 100.15 ≥ -23
Solving these two, we will get the maximum and minimum of the range.
The maximum is given by:
x - 100.15 ≤ 23
x ≤ 23 + 100.15 = 123.15
The minimum is given by:
x - 100.15 ≥ -23
x ≥ -23 + 100.15 = 77.15
Then the range is:
77.15 ≤ x ≤ 123.15

The numbers are
Answer:
1/2, 1/4
Step-by-step explanation:
Let the numbers be x and y.
Given, x=2y
1/x + 1/y = 6
plug in x=2y ,
1/2y+1/y = 6
Taking common denominator ,
(1+2)/2y = 6
2y = 3/6 = 1/2 => y=1/4
x = 2y = 2* 1/4 = 1/2
So, the numbers are 1/2 and 1/4

#1: what percent of 78 is 16?
#2: what is 79% of 55?
Answer:
1. 487.5%
2. 43.45
Step-by-step explanation:
Remember the formula for a proportion: ((part)/(whole)) = ((percent)/(100))
1.
The part is given, 78, and the whole is given, 16.
Set up a porportion:
78/16 = percent/ 100
Simplify:
39/8 = percent /100
Cross products
39/8 = percent/100
8percent = 3900
Inverse operations
8percent = 3900
/8 /8
percent = 487.5
487.5%
2.
The percent is given, and the whole is given.
Set up a proportion:
part/55 = 79/100
Cross products
part/55 = 79/100
100part = 4345
Inverse operations
100part = 4345
/100 /100
part = 43.45
43.45

The cost in dollars, y, of a large pizza with x toppings from Pat's Pizzeria can be modeled by a linear function. A large pizza with no toppings costs $14.00. A large pizza with toppings costs $17.50.
Given :
A large pizza with no toppings costs $14.00. A large pizza with toppings costs $17.50 .
To Find :
The cost in dollars y, of a large pizza with x toppings from Pat's Pizzeria.
Solution :
Let, equation is :
y = mx + c ....1)
Case 1 : With no toppings.
y = 14 = m(0) + c
c = 14
Case 2 : With 1 toppings i.e x = 1 .
y = 17.50 = m( 1 ) + c
17.50 = m + 14
m = 3.5
Putting value of c and m in equation 1, we get :
y = 3.5x + 14
Hence, this is the required solution.
