Answer:
r=4.998
Step-by-step explanation:
The equation for volume of a sphere is [tex]V = \frac{4}{3} \pi r^3[/tex].
We can subsatute 523 in for V and then solve for r by multiplying both sides by 3 and then dividing both sides by 4pi. Then, take the cube root of each side and you will get r.

Of all the apartments in an apartment building, 20 percent are single bedroom apartments and 30 percent of the single bedroom apartments have balconies. If 28 single-bedroom apartments do not have balconies how many apartments are there in this apartment building?
Answer:
200
Step-by-step explanation:
Of the apartments in the building, 20% are singles and 70% of those do not have balconies.
That is, (0.20 × 0.70) = 0.14 of the building's apartments are singles without balconies. That is 28 apartments. If A is the number of apartments in the building, this means
0.14A = 28
A = 200 . . . . . divide by 0.14
There are 200 apartments in the building.
A bag of flour weighs 2.5 kilograms.
About how much does the bag weigh in pounds ?
Round to the nearest tenth
I'll give you 55 points
Answer:
5.5 pounds
Explanation:
weight in kg = 2.5 kilograms
conversion:
1 kg ↔ 2.205 pounds
solve:
2.5 kilograms = (2.5 * 2.205)2.5 kilograms = 5.511557 pounds2.5 kilograms = 5.5 pounds ( rounded to nearest tenth )Answer:
5.5 pounds (nearest tenth)
Step-by-step explanation:
1 kilogram = 2.20462262 pounds
To determine how many pounds are in 2.5 kg, multiply by 2.5:
⇒ 2.5 kilograms = 2.20462262 × 2.5
= 5.5 pounds (nearest tenth)

Answer:
The answer is a = 99
Step-by-step explanation:
We can solve this using ratios
First we set up the equation:
[tex]\frac{a}{90}= \frac{110}{100}[/tex]
Then cross-multiply:
[tex]100 * a = 90 * 110[/tex]

The wheel of a bicycle has a diameter of 70cm and makes 2revolutions per second.calculate to one decimal place the speed of the bicycle in km/h
Answer:
Step-by-step explanation:
Number of reveloutions made in 1 second = 2
Number of revolutions made in 60 seconds ( 1 minute) = 2*60 = 120
Number of revolutions made in (60 minutes) 1 hour = 120 *60 = 7200
Circumference of circle = πd
[tex]= \dfrac{22}{7}*70\\\\\\= 22*10\\\\= 220 cm[/tex]
The distance traveled in 1 revoultion = the circumference of the cirlcle
= 220 cm
The distance travelled in 7200 revoultion = 7200 * 220
=1584000 cm
= 1584000 ÷ 100000
= 15.84 km
= 15.8 km
Speed = 15.8 km/h

The equation 3c = 4s gives the relationship between c, the weight of clay, and s, the weight of sand in a mixture. There are 6.25 pounds of clay in the mixture. What is the weight of the sand?
A. 4.69 pounds
B. 8.88 pounds
C. 18.75 pounds
D. 75.00 pounds
The weight of sand in the mixture when the weight of the clay in the mixture is 6.25 pounds is 4.69 pounds.
The equation can be represented as follows:
3c = 4s
How to find the variable in an equation?3c = 4s
where
c = weight of the clay in the mixtures = weight of sand in the mixtureHence,
3c = 4s
4s = 3c
let's make s the subject of the formula, since, we want to find s when c = 6.25 pounds
s = 3 / 4 c
s = 3 / 4 × 6.25
s = 18.75 / 4

What is the answer?
Step-by-step explanation:
120° + 20° + x = 180° ( sum of interior angle. of triangle is 180°)
140° + x = 180°
x = 180° - 140°
x = 40°
Now
y + x = 180° ( supplementary angle)
y + 40° = 180°
y = 180° - 40°
y = 140°
The angle measure of y is 140°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
The three angles of a triangle are 120°, 20° and x.
And we know,
the sum of the interior angle of the triangle is 180°.
120° + 20° + x = 180°
140° + x = 180°
x = 180° - 140°
angle measure of x = 40°
Now:
Here, x and y are supplementary angles.
Supplementary angles are two angles whose measures add up to 180°
y + x = 180°
y + 40° = 180°
y = 180° - 40°
y = 140°
Therefore, the value of y is 140°.

Answer:

Step-by-step explanation:
EDGE 2022
If product of two consecutive positive integers is 812 then the value of lesser integer is 28.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let's represent the lesser integer by x.
The next consecutive integer would be x + 1.
According to the problem, the product of these two integers is 812. So we can set up the equation:
x(x + 1) = 812
Expanding the left side and simplifying, we get:
x² + x = 812
Rearranging and factoring the left side, we get:
x² + x - 812 = 0
(x - 28)(x + 29) = 0
we can eliminate the negative value.
Therefore, the value of the lesser integer is 28. option B is correct.
