The height of a building is
480 feet. on a drawing of the building,
1/2 inch represents 24 feet, what is the
height of
building on the drawing?
Answer:
10 feet
Step-by-step explanation:
This is a problem of scale
where scale is
actual height of any object/ height of that object on drawing
given
actual height = 24 feet
this is represented 1/2 inch on drawing
thus
scale = actual height/ height on drawing = 24 feet/1/2 inch = 24*2 feet/ 1 inch
scale = 48 feet / 1 inch
given actual height of a building = 480 feet
let the height on drawing be x inch
thus
48 feet / 1 inch = 480 feet/ x inch
=> x inch/ 1 inch = 480 feet / 48 feet
=> x = 10 feet
Thus, the height of building on the drawing is 10 feet
At Rhonda’s diner, 5 loaded baked potatoes and 4 cheeseburgers provide 4830 calories. 1 loaded baked potato and 4 cheeseburgers provide 2630 calories. Find the calorie content of each item.
Answer:
Potato: 550 calories
Cheeseburger: 520 calories
Step-by-step explanation:
Equation:
5p + 4c = 4830
p + 4c = 2630
5p + 4c = 4830
p + 4c = 2630 ----------> p = -4c + 2630
5(-4c+2630) + 4c = 4830
-20c + 13150 + 4c = 4830
-16c + 13150 = 4830
-16c = -8320
C = 520
Cheeseburger = 520 calories
p + 4(520) = 2630
p + 2080 = 2630
p = 550
Potato = 550 calories

Alonzo works as a car detailer. He charges $165 per car. He is planning to move out of his parents' house and rent his first apartment. He will need to pay $105 for application fees, $895 for security deposit, and first and last months' rent at $1,120 per month. He has $1,919 in savings. How many cars must he detail to have enough money to rent the apartment?
Answer:
2 cars
Step-by-step explanation:
105 + 895 + 1120 = 2120
He has to pay 2120 of downpayment
2120 - 1919 = 201
Subtract what he already has
He needs 201 more dollars to rent his first apartment
He needs to do 1.21818182 cars...
You cant do 1/5 of a car so he has to do 2 cars
what is the base 8 representation of the number 11100111^2
Answer:
150161 in base 8.
= 347^2 base 8.
Step-by-step explanation:
11100111^2
the last 4 digits of this binary number = 7 in base 10.
The number 11100000 in base 10 = 1*2^5 + 1*2^6 + 1*2^7
= 224 base 10
So 11100111 = 231 base 10.
231^2 = 53361.
Now convert this to base 8:
We divide by 8
8 | 53361
8 | 6670 remainder 1
8 | 833 rem 6
8 | 104 rem 1
8 | 13 rem 0
8 | 1 rem 5
| 0 rem 1
So the answer is 150161

The average speed of a car during 5 hours is 50 miles per hour. What is the total distance traveled by the car?
Answer:
250 miles
Step-by-step explanation:
So we know that the time (t) equals 5 hours and that the rate (r) equals 50 mph. So knowing that, we can use the formula t*r=distance. We plug in the numbers and we get 250 miles.
Another way to think about this is, since we go 5 hours and 50 miles per hour, every hour we go 50 miles and we do that for 5 hours, so we go 50, 100, 150, 200, 250.
Find the value of h(-67) for the function below. h(x) = -49x − 125 A. 3,283 B. -3,408 C. 3,158 D. -1.18
Answer:
The answer is option CStep-by-step explanation:
[tex]h(x) = - 49x - 125[/tex]
To find h(-67) , substitute the value of x that's - 67 into h(x). That is for every x in h(x) , replace it with - 67
We have
[tex]h( - 67) = - 49( - 67) + 125 \\ = 3283 - 125[/tex]
We have the final answer as
h( - 67) = 3158Hope this helps you
Bobby's measuring cup holds 27 in3 of flour. He has enough flour to fill this measuring cup exactly 120 times. If his bread recipe calls for 36 oz of flour per loaf, and we know that 1 in.3 of flour weighs 0.4 oz, how many loaves of bread can Bobby make?
Answer:
Bobby can make 36 loaves of bread.
Step-by-step explanation:
The measuring cup holds 27in³ of flour
Since he has enough flour to fill this measuring cup exactly 120 times,
Therefore, he has 3,240in³ (27in³ * 120) of flour.
Given that 1in³ of flour weighs 0.4 oz,
This implies that there are 1,296 oz (3,240in³ * 0.4 oz) of flour
And since the bread recipe per loaf consumes 36 oz of flour,
Therefore, the number of loaves Bobby can make is: 36 (1,296 oz / 36 oz)
Answer:
36 loaves of bread!

four investors lost 24percent their combined investment in a company on average how much did each investor lose
Answer:
each investor lost 6 %
Step-by-step explanation:
24/4 = 6 %
The required average loss by an individual investor is 6%.
Given that,
four investors lost 24% of their combined investment in a company on average how much did each investor lose is to be determined.
Average of the values is the ratio of the total sum of values to the number of values.
What is simplification?The operation and interpretation of a mathematical function to make it simpler or easier to grasp is called simplification, and the process is known as simplification.
Here,
Total lost = 24%
Total investors = 4
Average = total lost / total investors
Average = 24 / 4 = 6%
Thus, the required average loss by an individual investor is 6%.

A very large bag contains more coins than you are willing to count. Instead, you draw a random sample of coins from the bag and record the following numbers of each type of coin in the sample before returning the sampled coins to the bag. If you randomly draw a single coin out of the bag, what is the probability that you will obtain either a nickel or a penny? Enter a fraction or round your answer to 4
4
decimal places, if necessary.
Answer:
0.15890.35510.5140Step-by-step explanation:
Number of coins are as per table below
Quarters ≡ Dimes ≡ Nickels ≡ Pennies 23 ≡ 29 ≡ 17 ≡ 38Total number of coins
23+29+17+38 = 107Probability = favorable outcomes / total outcomes
P(nickel) = 17/107 = 0.1589 roundedP(penny) = 38/107 = 0.3551 roundedP(nickel or penny) = (17+38)/107 = 0.5140 roundedAccording to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267 . Suppose you sit on a bench in a mall and observe people's habits as they sneeze. (a) What is the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing? (b) What is the probability that among 12 randomly observed individuals fewer than 6 do not cover their mouth when sneezing? (c) Would you be surprised if, after observing 12 individuals, fewer than half covered their mouth when sneezing? Why?
Answer: kindly check explanation
Step-by-step explanation:
Probability of not covering mouth = p(success) = 0.267
Hence, p(covering mouth) = 1 - 0.267 = 0.733
a) What is the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing?
Number of samples (n) = 12
P(X = 8)
Using binomial distribution :
P(x) = nCx * p^x * (1-p)^(n-x)
P(x =8) = 12C8 * 0.267^8 * 0.733^(12-8)
P(x =8) = 12C8 * 0.267^8 * 0.733^4
= 0.00369
b) What is the probability that among 12 randomly observed individuals fewer than 6 do not cover their mouth when sneezing?
P(X < 6) = p(5) + p(4) + p(3) + p(2) + p(1) + p(0)
To save computation time, we can use an online binomial probability calculator :
P(X < 6) = 0.9275
C.) Yes, I will be surprised, because from the binomial probability obtained above, there is a high probability (0.9275) that fewer than half do not cover their mouth.

a ladder 10cm rest on a vertical wall of 8cm what is the distance of the vertical Wall from the Foot of the ladder
Hi there!
[tex]\huge\boxed{6cm}[/tex]
We can use the Pythagorean Theorem to solve:
Use the formula a² + b² = c² where:
"a" and "b" are the legs
"c" = Hypotenuse
The diagonal side, or the length of the ladder is 10cm, and one of the legs of the triangle is 8cm, therefore:
(8)² + b² = 10²
64 + b² = 100
Subtract 64 from both sides:
b² = 36
Take the square root of both sides:
√b² = √36
b = 6 cm. This is the distance of the wall from the foot of the letter.
Edit: Typo.
Answer:
6 cm.
Step-by-step explanation:
When you imagine the sentence, it is a right angled triangle. In this case, it's a Pythagoras Theorem. The formula for it is:
a²(opposite) + b²(adjacent) = c²(hypotenuse)
The vertical wall is the opposite, the distance between the foot of the ladder and the wall is the adjacent, while the ladder is the hypotenuse.
We have the measurements except for the adjacent. So it will be:
c² - a² = b²
10² - 8² = b²
100 - 64 = b²
36 = b²
√36 = b
b = 6 cm
The answer is 6 cm.
