Answer:
8 years
Step-by-step explanation:
Shaniquas age is given as 36. This age is going to help us to find the rest.
Pablo is said to 1/3 of Shaniquas age
= 1/3 of 36 = 36/3 = 12
Pablo is 12
Danny is younger than pablo by 1
12 - 1 = 11
Danny is 11
Terrell is younger than danny by 3
11-3 = 8
Terrell is 8 years old
Answer:
[8, 44]
Step-by-step explanation:
The average of equally-weighted values is their sum divided by their number.
<h3>Setup</h3>
For some fourth test score x, Paul wants an average between 70 and 79. This gives rise to the inequality ...
70 ≤ (91 +88 +93 +x)/4 ≤ 79
<h3>Solution</h3>
Multiplying by 4, we have ...
280 ≤ 272 +x ≤ 316
8 ≤ x ≤ 44 . . . . . . . . . . subtract 272
Paul will get a C if his fourth test score is in the interval [8, 44].
Answer:
3cm/s
Step-by-step explanation:
Area of a square is expressed as:
A = L²
Rate of change of area is expressed as:
dA/dt = dA/dL•dL/dt
Given that
dA/dt = 24cm²/s
L = 4cm
Required
dL/dt
Since dA/dl = 2L
dA/dl = 2(4)
dA/dl = 8cm
Subatitute the given values into the formula
24 = 8 dL/dt
dL/dt = 24/8
dL/dt = 3cm/s
Answer:
16.8
Step-by-step explanation:
Assuming the triangles are similar, write a proportion to find x.
Cross multiply the numerator and denominator of each fraction.
20x=30(28-x)
20x = 840 - 30x
50x = 840
x = 16.8
