Answer: 1/3.(√3/4)×40×40 ×5√(5
Step-by-step explanation:
Answer:
200 m^3
Step-by-step explanation:
1) find the side of the base
side = 40 : 4 = 10 m
2) find the base area
base area = side^2 = 10^2 = 100 m^2
3) find the Volume
V = (base area x height)/3 = (100 x 6)/3 = 200m^3

Answer:
A) $157,555
Step-by-step explanation:
The sum of assets is ...
house + 2 cars = $280,000 +5,200 +15,600 = $300,800
The sum of liabilities is ...
mortgage +car loan +credit card +wedding
= $113,545 +9,200 +2,300 +18,200 = $143,245
The family's net worth is the difference between assets and liabilities:
$300,800 -143,245 = $157,555

A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100. You scored a 625. Calculate your z-score to the nearest hundredth (i.e. 2 decimal places).
z=
Answers
Answer: The required z-score = 1.25
Step-by-step explanation:
Let x be a random variable that denotes the scores in the exam.
The formula for z-score = [tex]\dfrac{X-\text{mean}}{\text{standard deviation}}[/tex]
As per given, we have
X= 625, mean=500, standard deviation = 100
Z-score = [tex]\dfrac{625-500}{100}[/tex]
i.e. Z-score = [tex]\dfrac{125}{100}[/tex]
i.e. Z-score =1.25
Hence, the required z-score = 1.25
Which of the following are mathematical sentences? Check all that applu
A. 4- d= 12
B. 4-V> 2
C. 3 + 2
D. 59
E. 6 + a = 13
F. 12x
Answers
Answer:
The correct options are:
A, B, and E.
Step-by-step explanation:
A mathematical sentence (or a mathematical statement) is a sentence that can be true or false.
This is the only criteria we need to check, now let's analyze each option.
A: 4 - d = 12
This can be true or false, for example, if d = 0 the sentence is false because:
4 - 0 = 12
4 = 12 is false.
and if d = -8 the sentence is true, because:
4 - (-8) = 12
4 + 8 = 12
12 = 12
is true.
B: 4 - V > 2
This sentence can be true or false, same reasoning as before, we can find values of V such that this is true or false.
C: 3 + 2
Now, here we can't say if this is true or false, so this is not a mathematical sentence.
D: 59
Same as before, this is just a number.
E: 6 + a = 13
This can be true or false, depending on the value of a, then this is a mathematical sentence.
F: 12*x
Here we can not say if this is true or false, so this is not a mathematical sentence.
The correct options are:
A, B, and E.

Compound interest is the interest generated on a sum of money invested. The amount of money that you will have in your account after 25 years is $122,653
How to calculate the compound interest?Compound interest is the interest generated on a sum of money invested. The formula for calculating compound interest is expressed as:
A = P(1+r/n)^nt
Given the following parameters
Principal P = $3600 (a year)
rate r = 0.03
Time t = 25 years
n = 12 (time of compounding)
Substitute
A = 3600(1 + 0.03/12)^12(25)
A = 3600 (1.0025)^300
A = 3600(2.1150)
A = $122,653
Hence the amount of money that you will have in your account after 25 years is $122,653

Option 4
Step-by-step explanation:
Area of shaded region = Area of the circle - Area of the shaded triangles
Area of the circle = πr²
r = Radius of the circle
Therefore, area of the circle = π(4)²
= 16π
Area of the given triangles = [tex]2[\frac{1}{2}(\text{Base})(\text{Height})][/tex]
= Base × Height
= (4 × 4)
= 16

Line t is tangent to the circle . Find AB (click photo)
Answers
Answer:
mAB=130°
Step-by-step explanation:
The tangent-chord theorem tells us that the angle the tangent makes with the curve (65°) is half the measure of the arc (mAB):
mAB=2(65)=130°
The value of measure of arc AB is,
⇒ m AB = 130°
What is mean by Angle?
An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Line t is tangent to the circle.
Now, We know that;
The tangent-chord theorem tells us that the angle the tangent makes with the curve is half the measure of the arc.
Hence, We can formulate;
⇒ m AB = 2 × 65°
= 130°
Thus, The value of measure of arc AB is,
⇒ m AB = 130°

On rainy weekend days, the probability that Karen bakes bread is
90%. On the weekend, the probability of rain is 50%. There is a 29%
chance that today is a weekend day. What is the probability that today
is a rainy weekend day in which Karen is baking bread?
Answers
9514 1404 393
Answer:
13%
Step-by-step explanation:
The probability is the product of the individual probabilities.
p(baking | rainy weekend) = 0.90
p(rainy weekend) = p(rain | weekend) × p(weekend) = 0.50×0.29 = 0.145
Then ...
p(baking) = p(baking | rainy weekend) × p(rainy weekend) =
0.90 × 0.145 = 0.1305 ≈ 13%
