Answer:
x = 39
Step-by-step explanation:
The angle between a tangent and the radius of a circle at the point of contact is 90° , then
x = 180 - (90 + 51) = 180 - 141 ← angle sum of triangle
x = 180 - 141 = 39
x + 51 = 90
x = 90 - 51
x = 39°

The a question is attached below
Answer:
22.2m
Step-by-step explanation:
vol of a sphere = 4/3 x pi x r^3
vol of a hemisphere is 1/2 the vol of a sphere, so vol of a hemisphere= 2/3 x pi x r^3
2/3pi x r^3 = 257
Divide both sides by 2/3pi
r^3 = 122.708
Cube root both sides.
r = 11.077
Diameter is twice the radius, so diameter = 22.154m
To the nearest 10th of a meter this is 22.2m.

Lea,Paul and Tynos invest in a business in the ratio 2:3:5.if the profit from the business is $450 000.how much does each person get?
Answer:
see explanation
Step-by-step explanation:
Sum the parts of the ratio, 2 + 3 + 5 = 10 parts
Divide the profit by 10 to find the value of one part of the ratio.
$450 000 ÷ 10 = $45 000 ← value of 1 part of the ratio, then
2 parts = 2 × $45 000 = $90 000 ← Lea's share
3 parts = 3 × $45 000 = $135 000 ← Paul's share
5 parts = 5 × $45 000 = $225 000 ← Tynos' share

Answer:
You know that the Pythagorean Theorem is:
a²+b²=c²
,
Where:
a
is the length of one of the legs,
b
is the length of the other leg, and
c
is the length of the hypotenuse.
You know the lengths of the two legs are
7 and 11
, so we'll say that
a is 7 , and b is 11
Knowing that, we can plug those into our equation and simplify like so:
7²+11²=c²
49+121=c²
170=c²
√170=c
c=13.0384
Answer:
√72Step-by-step explanation:
Use Pythagorean:
h² + (14/2)² = 11²h² + 49 = 121h² = 121 - 49h² = 72h = √72 inWhat decimal is equivalent to 13/20?

what is the equation of the trend line in the scatter plot ? HELP ME HURRY ILL MARK BRAINLIEST
Answer:
[tex] y = \frac{3}{7} x + 3 [/tex]
Step-by-step explanation:
Line is passing through the points (0, 3) and (7, 6)
So, y-intercept (b) = 3
Slope of the line (m) = (6 - 3)/(7 - 0) = 3/7
Equation of line in slope-intercept form is given as :
y = mx + b
Plugging the values of m and b in the above equation, we find:
[tex]y = \frac{3}{7} x + 3 \\ [/tex]

Take milk to to be M and snack bars to be S.
Use algebra, so
2m + 3s = 64 and also
4m + 2s = 72
Multiply the top equation by 2 so both have 4m, so
4m + 6s = 128 and also
4m + 2s = 72
Then minus the numbers form the top equation by the bottom equation, so
4m + 6s = 128
- - -
4m + 2s = 72
This gives you 4s=56 so divide by 4 so s=14
No put 14 into the equation for s and rearrange to solve for m, so
2m+3s=64 So
2m+3x14=64
2m+42=64
Then minus 42
2m=22
m=11
Derrick wants to calculate the interest he would earn from investing $400 into an account that earns 5.5% annual compound interest for 60 months. Which of the following formulas is set up correctly to help him do this?
Answer:
c
Step-by-step explanation:
The formula that should be set up correctly to help him do this should be considered as the [tex]400(1 + 5.5\%)^{60}[/tex]
Calculation of the formula:Since
the invested amount is $400
The annual compound interest is 5.5%
And, the number of months should be 60
So here the formula that should be used should be [tex]400(1 + 5.5\%)^{60}[/tex]

-22 - 49 = -71
Answer:
23
-71
Step-by-step explanation:
11 - (-12) = ?
-22 - 49 = ?
11 - ( -12) = 11 + 12 = 23
-22 - 49
subtracting a negative from a negative is like adding a positive to a positive it has the same affect just a different sign
-22 - 49 = -(22 + 49)
22 + 49 = 71
-(71) = -71

Find the output, ddd, when the input, ttt, is 111111. d =-20+11td=−20+11td, equals, minus, 20, plus, 11, t d=d=d, equals
Answer:
d=101
Step-by-step explanation:
If 11 is being multiplied by t, and t is 11, we multiply 11 by 11, we get 121.
After adding that to our equation, we get -20 + 121, which equals 101.
Therefore d=101
The value of d, when t = 11 is equal to 141.
What is a function?
An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -
f(x) = 4x + 6
Given is the following equation -
d = - 20 + 11t
We have -
d = - 20 + 11t
for t = 11, we get -
d = 20 + 11 x 11
d = 20 + 121
d = 141
Therefore, the value of d, when t = 11 is equal to 141.

it takes eight blocks with side links of a quarter m to fill a rectangle or prism the rectangular prism has a volume of what in Cubic meters
Answer:
1/8 m³
Step-by-step explanation:
Given that:
Side length of block, s = 1/4
Volume of block, V
V = s³
Volume of block = (1/4)³ = 1/4 * 1/4 * 1/4 = 1 /64
The rectangular prism takes 8 of this blocks :
Hence, the volume of the rectangular prism is :
Number of blocks * Volume per block
8 * 1 /64
8 /64
= 1/8 m³
