Answer:
20
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
21^2 + b^2 = 29^2
441 + b^2 = 841
Subtract 441 on both sides to get b^2 = 400
Take the square root of both sides to get b = 20

Find the value of x explain how you got your answer
Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.
step 2: x+50+4x=90
x+4x=50
5x=50
x=10
then you solve the equation, x is 10
Find the areas of a circle whose diameter is 21 cm
Answer:
Your answer is 346.36059
Step-by-step explanation:
A = pi*r²
A = pi * 10.5²
A = pi * 110.25
A = 346.36059
We can write the the area of the circle as 110.25π square centimeter.
What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is a circle whose diameter is 21 cm.
It is asked to find the area of a circle whose diameter is 21 cm.
It is given that the diameter of the circle is -
d = 21 cm
r = d/2 = 21/2
r = 10.5 cm
We know that the area of the circle as -
Area = πr²
Area = π x 10.5 x 10.5
Area = 110.25π
So, it can be concluded that the area of the circle is 110.25π square centimeter.
Therefore, we can write the the area of the circle as 110.25π square centimeter.

Please help with number 12
Answer:
61
Step-by-step explanation:
Answer:
Step-by-step explanation:
12)
we are told that ∠ABD = 61°
then we also know that ∠ADB = 61° b/c there are the equal legs of an isosceles triangle.
and we know by inspection that the ΔBCD is identical to ΔABD so it also has 61° angles so
∠ABC = 61 + 61 =122°

C. 700 units.
The formula for the surface area of a rectangular prism is: 2 ((Width × Length) + (Height × Length) + (Height × Width))
(14 × 12) + (7 × 12) + (7 × 14)
168 + 84 + 98 = 350

simon will deposit $250 into two savings accounts. account 1 earns 1.6% interest compounded annually. account 2 earns 1.6% simple annual interest. if simon makes no additional deposit or withdrawals, which account is closest to the difference in the interest that the account will have earned at the end of 10 years. A. $253.01 B.$43.01 C.$83.01 D.$3.01
The difference in the interest that the account will have earned at the end of 10 years is of:
D. $3.01.
What is the account 1 interest earned?The amount of interest earned, in compound interest, after t years, is given by:
[tex]I(t) = P\left(1 + \frac{r}{n}\right)^{nt} - P[/tex]
In which the variables are listed as follows:
P is the principal.r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.In the context of this problem, these parameters are given as follows:
P = 250, r = 0.016, n = 12, t = 10.
Hence the interest earned by account 1 is:
[tex]I(10) = 250\left(1 + \frac{0.016}{12}\right)^{12 \times 10} - 250 = 43.35[/tex]
What is the account 2 interest earned?For simple interest, the amount of interest earned is:
I(t) = Prt.
Hence:
I(10) = 250 x 0.016 x 10 = 40.
Hence the difference is:
43.35 - 40 = $3.35.
Which is closest to option D.
