#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
One number is 2 times another. The sum of their reciprocals is 6. Find the numbers.
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
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

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

A rectangular prism has dimensions of 2 cm by 2 cm by 5 cm. What is its surface area?
∣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

Ilona is at a friend's home that is several miles from her home. She starts walking at a constant rate in a straight line toward her home. The expression -2t+10 gives the distance in miles that Ilona is from her home after t hours
Complete question is;
Ilona is at a friends home that is several miles from her home. She starts walking at a constant rate in a straight line toward her home.
The expression -2t + 10 gives the distance, in miles, that Ilona is from her home after t hours. Select True or False for each of the following.
1. The friends home is 10 miles from Ilonas home
2. The distance Ilona has walked away from her friends home after t hours is given by the absolute value of -2t
3.The negative sign in the term indicates that Ilona is walking toward her home
4. Ilona is walking at a rate of 10 miles per hour
Answer:
Statements 1 & 2 are correct.
Step-by-step explanation:
We are told that the expression -2t + 10 gives the distance, in miles, that Ilona is from her home after t hours.
Now, we know that distance = speed x time
Now, from the expression -2t + 10
It's clear that 2t is a distance value.
This means that the speed used in going home is 2 miles/hr
This means that at t hours, she has walked 2t miles from her friends home.
Thus, statement 2 is true because an absolute value of -2t will be 2t.
Since 2t is subtracted from 10 in the expression and 2t is the distance she has walked from her friends house at Time, t. It means that 10 miles is the distance from her friends house to her house.
Thus, statement 1 is also true

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

Consider the rational number 3/11 a. What are the value of a and b in a divide by b when you use division to find the decimal form b. What is the decimal form for 3/11
Answer:
The decimal form of this rational number is [tex]0.\overline {27}[/tex].
Step-by-step explanation:
a) Let [tex]\frac{a}{b}[/tex] a rational number. From statement we understand that [tex]a[/tex] represents the numerator, while [tex]b[/tex] corresponds with the denominator of the rational number. Hence, [tex]a[/tex] is 3 and [tex]b[/tex] is 11.
b) The decimal form is obtained by dividing [tex]a[/tex] by [tex]b[/tex], we presented the step needed to determine the decimal form:
i) Multiply the numerator by 10:
Dividend: 30/Divisor: 11/Known result: 0. /Residue: N/A
ii) Multiply the divisor by 2 and subtract from the dividend:
Known result: 0.2 /Residue: 8
iii) Multiply the residue by 10:
Known result: 0.2 /Residue: 80
iv) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.27 /Residue: 3
v) Multiply the residue by 10:
Known result: 0.27 /Residue: 30
vi) Multiply the divisor by 2 and subtract from the residue:
Known result: 0.272/Residue: 8
vii) Multiply the residue by 10:
Known result: 0.272 /Residue: 80
viii) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.2727/Residue: 3
We have notice that the decimal form of [tex]\frac{3}{11}[/tex] is a periodical decimal number. Hence, we conclude that decimal form of this rational number is [tex]0.\overline {27}[/tex].

Answer:
C) 25
Step-by-step explanation:
The exponents are only even numbers, which are divisible by 2.
If the last number is 50, divide it by 2.
1 to whatever power will always be 1 and there are 25 numbers, so 25.
Answer:
C) 25
Step-by-step explanation:
1 to the power of anything will always be 1, so we can eliminate the exponents. Now, we're left with 1 + 1 + 1 + ... + 1. The question is, how many 1s are in this list? We can refer back to the original problem to figure this out. Notice that the exponents are every other number from 1 to 50, so the number of 1s in the list is 50 / 2 = 25. Therefore, the answer is 25 * 1 = 25. Hope this helps!

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
