pleas help with the khan academy question
Answer:
1. 10
2. 4
3. 8
Step-by-step explanation:
You have to fill in the given values for y and undo in reverse order to find x.
1. y = 6
6 = x - 4
6 (+ 4) = x - 4 (+ 4)
10 = x
2. y = 0
0 = x - 4
0 (+ 4 ) = x - 4 (+ 4)
4 = x
3. y = 4
4 = x - 4
4 (+ 4) = x - 4 (+ 4)
8 = x

Find the area of the shaded polygons. Pls help! Person will get brainlist.
Answer:
Triangle - 17.5
Trapezoid - 64
Step-by-step explanation:
Triangle - This is because the triangle formula is h x b/2 and H is 7 and B is 5 so 5 x 7 is 35 divided by 2 is 17.5.
Trapezoid - a + b/2 times h and A is 6, B is 10 and H is 8 so 6+10 = 16 and 16/2 equals 8 and 8 x 8 =64.
If the population of Alaska in 2000
was 622,000 and 733,000 in 2020,
assuming exponential growth, what
would the population be in 2050?
[ ? ] people
The number of people by the year 2050 is obtained as 927915 people.
What is the population in 2050?We know that population is an exponential growth problem in this case. We have to apply the formula;
P = Poe^rt
P = population at time t
Po = Initial population
r = population growth rate
t = time taken
Now;
We have to use the relation to find the growth rate as follows;
733,000 = 622,000 e^20r
733,000/622,000 = e^20r
1.178 = e^20r
ln(1.178) = 20r
r = ln(1.178)/20
r = 0.008
Now;
In the year 2050, we would have;
P = 622,000 e^50 * 0.008
P = 927915 people

Alex surveyed twenty boys from his class. He asked their height in centimeters and their shoe size. Alex wanted to know if these two variables were related. He graphed the results on the coordinate plane. Each graph below shows Alex’s data.
Which of the graphs shows the best linear fit for the data?
The graph that has a linear fit that is best for the data that Alex collected is the graph attached.
Which graph shows the data best?A linear fit that would be best for Alex's data is one that tries to get an equal number of shoe sizes on both sides of the line.
The shoe sizes should also be a roughly equal distance to the line and the line should be drawn in the middle of the data. The line that does this best is shown attached.

The number of hot dogs sold: ?
At a basketball game, a vendor sold a combined total of 197 sodas and hot dogs. The number of hot dogs sold was 41 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold .
Given : -Total of sodas and hot dog sold = 197No. of hot dogs sold = 41 less than the no. of sodas soldTo Find : -No. of soda soldNo. of hot dog soldConcept : -We have to solve this question by making equation and after creating equations we have to solve them properly to get the final answer .
To Assume : -Let the no. of soda sold be x .Let the no. of hot dogs sold be x - 41 ( Because they are 41 less than sodas )So Starting Solution : -According to question we know that combined total of sodas and hot dogs is :
x + ( x - 41 ) = 197x + x - 41 = 1972x - 41 = 1972x = 197 + 412x = 238x = 238/2x = 119Therefore , No. of sodas sold is 119 .
Now , Hot dogs :
x - 41 119 - 41 78Therefore , No. of hot dogs sold is 78 .
Verifying :We know that their combined sum is equal to 197 . So ,
Sodas + Hot Dogs = 197119 + 78 = 197197 = 197L.H.S = R.H.STherefore , our answer is valid .

If a single card is drawn from a standard 52-card deck, what is the probability it is a diamond or a face card (Jack, Queen, or King)?
A. 11/26
B. 2/7
C. 1/4
D. 2/52
Using it's concept, it is found that the probability that the card is a diamond or a face card is given by:
D. 25/52
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
A standard deck has 52 cards, of which 13 are diamond and 12 are face, hence:
p = (13 + 12)/52 = 25/52.
Which means that option D(25/52) is correct.

Answer:
5.946 cm
Step-by-step explanation:
Using the Pythagorean Theorem, we know that in a right angle triangle to find the longest side we must use the equation a^2 = b^2 + c^2
A is the longest side while b and c are the other two sides
To find one side we must use
b^2 = a^2 - c^2
a squared = 6.9 squared - 3.5 squared
a^2 = 35.36
square root 35.36 to get a
a = 5.946427499

Answer:
100.32
Step-by-step explanation:
First, we have to find 14% of 88
14% of 88 is = 88 x 14/100
= 12.32
Now we have to increase the number 88 by 14%, which means we have to add 14% of 88 (12.32) to the given number (88)
88 + (14% of 88)
= 88 + 12.32
=100.32

Answer:
Answer is equation C
Step-by-step explanation:
They are converting Celsius temperature to Fahrenheit temperature.
F = 1.8C + 32
F = 1.8(0) + 32 = 32 Fahrenheit
F = 1.8(30) + 32 = 86 Fahrenheit
F = 1.8(100) + 32 = 212 Fahrenheit
Answer:
C) F = 1.8C + 32
Step-by-step explanation:
Hello! The easiest way to do this is to substitute the numbers from your table into your possible answer choices until you find numbers that make a true/correct statement.
For A:
F = 32C + 1.8 <== substitute any number for F and C from your table
32 = 32(0) + 1.8 <== multiply
32 = 0 + 1.8 <== add
32 = 1.8
This statement is false/incorrect
For B:
C = 1.8F + 32 <== substitute any number for F and C from your table
0 = 1.8(32) + 32 <== multiply
0 = 57.6 + 32
0 = 89.6
This statement is false/incorrect
For C:
F = 1.8C + 32 <== substitute any number for F and C from your table
32 = 1.8(0) + 32 <== multiply
32 = 0 + 32 <== add
32 = 32
This statement is true/correct
For D:
C = 32F + 1.8 <== substitute any number for F and C from your table
0 = 32(32) + 1.8 <== multiply
0 = 1024 + 1.8 <== add
0 = 1025.8
This statement is false/incorrect
As we can see, the only equation that makes a true statement is C.
Therefore, the correct answer is C.
Hope this helps!
