Answer:
98%
Step-by-step explanation:
Test 1 - 83%
Test 2 - 91%
Test 3 - 88%
Test 4 - ?
If we use x to represent Test 4, we can create the following equation:
1/4 (83 + 91 + 88 + x) = 90
We find the average here by adding up the four test scores and dividing by 4.
Proceed to solve it:
1/4 (262 + x) = 90
262 + x = 360
x = 98
Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

There are 2 questions please answer them both
Answer:
Concept: Graph Analysis
Take a look at the first graph. Notice it goes through (0,-2) and the slope is 5/2 so the answer is A.Next to find the equation we look at the y-intercept and determine that its -2 and the slope is -5/2. Hence the answer is CStep-by-step explanation:
Problem 1.
Start at (0, -2). Go up 5 and right 2. That is a slope of 5/2.
First choice.
Problem 2.
The y-intercept is (0, -2), so b = -2.
Start at (0, -2). Go down 5 and right 2. That is a slope of -5/2.
y = mx + b
y = -5/2 x - 2
Third choice

A tepee is designed to have a diameter of 10 feet and a volume of 366 feet at what h Igor should the support poles cross to assemble the tepee (round ur answer to the nearest foot)
Answer:
A. 14ft
Step-by-step explanation:
First get the cones volume formula v=(3.14*r^2*h)/3
Second find the radius which is 1/2 the diameter.
Third plug in given and solve 366= (3.14*5^2*h)/3
366*3=3*(3.14*25*h)/3
1098=78.5h
1098/78.5=78.5h/78.5
13.987=h

GIVING BRAINLIEST !!!!!!
Answer:
A.
Step-by-step explanation:
If we assume that the population of the town is proportional to the random people selected to take the survey, then we can say that the answer is A, People at least 50 years old are the largest age group in town. Since the survey is random and the percentage of the 50-year old population group is higher when individually compared to the other groups, we can assume that the town's population consists of a high number of people who are 50-years old or older.
And although it is not a given answer choice, it would actually make more sense to say that out of the number of people that took the survey, those who were 50 years old or older consisted of the largest age group.

Answer:
For the first one
x= About 32.02
y= About 27.58

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!
Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year. How old are Mary and Beth?
The age of Mary and the age of Beth will be 10 years and 4 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.
Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.
3x + y = 34 ...1
x/2 - y = 1 ...2
From equations 1 and 2, then we have
3(2y + 2) + y = 34
6y + 6 + y = 34
7y = 34 - 6
7y = 28
y = 4
Then the value of the variable 'x' is given as,
3x + 4 = 34
3x = 30
x = 10
The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

Answer:
35 carrots & 63 cucumbers
Step-by-step explanation:
Add both of the numbers in the ratio (5 + 9 = 14) Then take that sum and divide 98 by that sum (98/14). Whatever the quotient is, multiply each number in the ratio by that. (98/14 = 7) (5 x 7 and 9 x 7)
