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

Si ella da dos vueltas alrededor de este, ¿qué distancia en metros recorre? Selecciona la opción correspondiente: a) 160 metros b) 330 metros c) 166 metros d) 332 metros
Answer:
1) c) 96 cm
2) c) 17,15 m
3) c) 294 m
4) d) 332 metros
Step-by-step explanation:
1)
La fórmula para el perímetro de un rectángulo = 2L + 2W
= 2 (largo + ancho)
L = longitud
W = ancho
Se nos dice en la pregunta que:
La longitud de un rectángulo es tres veces su ancho. Si el ancho es de 12 cm
Por lo tanto,
L = 3 W
L = 3 × 12
Largo = 36cm
Por lo tanto, el perímetro =
2 (largo + ancho) cm
= 2 (36 + 12) cm
= 2 (48) cm
= 96 cm
2)
La fórmula para el perímetro de un heptágono regular = 7a
Donde a = longitud de un lado
De la pregunta,
a = 2,45 m laterales
Por lo tanto, el perímetro de un Heptágono regular = 7 (2,45 m)
= 17,15 m
3)
La fórmula para el perímetro de un rectángulo = 2L + 2W
= 2 (largo + ancho)
L = longitud
W = ancho
Se nos dice en la pregunta que:
Si un campo de fútbol tiene 98 m de largo y su ancho es igual a la mitad de esta medida,
Por lo tanto,
L = 98 m
W = 1/2 de longitud
Ancho = 1/2 (98)
= 49
Por lo tanto, el perímetro =
2 (largo + ancho) m
= 2 (98 + 49) m
= 2 (147) m
= 294 m
4)
El parque es de forma rectangular.
Longitud = 45 m
Ancho = 38.000 mm
Convertir mm en m
1 milímetro = 0,001 metro
38.000 milímetro =
38.000 × 0,001 metros
= 38 metros (38 m)
La distancia alrededor del parque = perímetro del parque
Perímetro = 2 (L + W)
= 2 (45 + 38)
= 2 (83)
= 166 m
Distancia alrededor del parque una vez = 166 m
Pero nos dijeron que dio la vuelta al parque 2 veces, por lo tanto, la distancia que recorrió = 166 m × 2
= 332m
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.

hi can you please help me
Answer:
x = 25
y = 21
Step-by-step explanation:
4x + 10 + 3x - 5 = 180° because these two angles makes a straight line
7x + 5 = 180° subtract 5 from both sides
7x = 175° divide by 7
x = 25
2y + 28 + 4y + 26 = 180° because the sum of these angles is equal to a straight line's measure
6y + 54 = 180° subtract 54 from both sides
6y = 126 divide both sides by 6
y = 21

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!

30 degrees
Step-by-step explanation:
∠BAC= ∠DAE (vert. opp. ∠s)
(x +10)°= (2x -10)°
x +10= 2x -10
Bring constants to 1 side, x terms to the other:
2x -x= 10 +10
x= 20 (simplify)
∠BAC= (x +10)°
∠BAC= (20 +10)° (substitute x=20)
∠BAC= 30°
Answer:

Step-by-step explanation:
<bac=<ead (being vertically oppoaite angles)
(x+10)=(2x-10)
10+10= 2x-x
20°=x
now
<bac=(x+10)°

Find the mean of the integers -45 -20 -35 -25 -40
Answer:
-33
The mean of the data set -45, -20, -35, -25, and -40 is -33.
Hope it helps.
The mean of given integers is -35.

According 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.

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 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.
