The formula of pyramid:
Where v is the volume, a is the base area and h is the height.
We can then put the given information into the formula:
176 = (1/3)(3x × x)(11)
(176 × 3) / 11 = 3x^2
3x^2 = 48
x^2 = 48/3
x = _/16
x = 4
Answer:
D) ½
Step-by-step explanation:
∛(x√x) = xᵇ
Cube both sides.
x√x = x³ᵇ
Square both sides.
x² x = x⁶ᵇ
x³ = x⁶ᵇ
Equate the exponents.
3 = 6b
b = ½
Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
Answer:
The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit.
Step-by-step explanation:
3a + 2c = 275 .... t-shirt costs $3 per adult and $2 per child and <span>total money collected was $275
</span>
a + c = 100 ... the total number of adults (a) and children (c) who bought shirts was 100
so
3a + 2c = 275
a + c = 100 so a = 100 - c
substitute a = 100 - c into 3a + 2c = 275
3a + 2c = 275
3(100 - c) + 2c = 275
300 - 3c + 2c = 275
-c = - 25
c = 25
a = 100 -c = 100 - 25 = 75
so a = 75 (adults) and c = 25 (children)
answer
<span>Equation 1: a + c = 100
Equation 2: 3a + 2c = 275
25 children and 75 adults</span>
