Answer:
m<ADC = 107
Step-by-step explanation:
You need to know three things to solve this problem.
1) Opposite angles of an inscribed quadrilateral are supplementary.
2) The measure of an inscribed angle is half the measure of its subtended arc.
3) The sum of the measures of all the arcs of a circle is 360 deg.
From 1) we get:
m<A + m<C = 180
72 + m<C = 180
m<C = 108
From 2) we get:
m<C = (1/2)m(arc)BAD
108 = (1/2)[m(arc)AB + m(arc)AD]
216 = m(arc)AB + 122
m(arc)AB = 94
From 3) we get:
m(arc)AB + m(arc)BC + m(arc)CD + m(arc)DA = 360
94 + 120 + m(arc)CD + 122 = 360
m(arc)CD = 24
From 2) we get:
m<ADC = (1/2)m(arc)ABC
m<ADC = (1/2)[m(arc)AB + m(arc)BC]
m<ADC = (1/2)[94 + 120]
m<ADC = 107

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.

Karla has spent $39 on food. She bought milk, cheese, and meat. The milk cost half as much as the cheese and the meat cost four times as much as the cheese. Which equation would help you find the cost of the cheese?
Let c = the amount spent on cheese
Click on the correct answer:
1)C+ 4c/5c=39
2)C+2c + 4c = 39

and round to the nearest hundredth
Answer:
Volume = 1659.84Surface area = 1205.36Step-by-step explanation:
Volume for triangular prism = 1/2 * b * l * h
we are given the length and the height but not the base.
since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2
13.3^2 + b^2 = 20.5^2
176.89 + b^2 = 420.25
b^2 = 243.36
b = [tex]\sqrt{243.36}[/tex] = 15.6
1/2 (15.6)(13.3)(16) = 1659.84
Front: 15.6 x 13.3 = 207.48
Back: 15.6 x 13.3 = 207.48
Left: 15.6 x 16 = 249.6
Right: 13.3 x 16 = 212.8
Bottom: 20.5 x 16 = 328
207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36

Which of the following is a continuous random variable?
A. X= number of incoming flights at the local airport
B. T=winning time in the man's 100 meter dash at the 2016 Olympics
C. P=number of points scored by Stephen curry in a game
D.H=The number of hats sold on Tuesday
Answer:
option A
Step-by-step explanation:
because it is not limited to anything while option b is limited to the men's hundred meter dash and 2016, and to the Olympics
C is limited to one game and stephen curry
D is limited to tuesday
since option a isn't confined to one day, person, or specific event there can be endless numbers assigned to the variable
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:

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

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

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

-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
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.
