of the problems on her homework before dinner. She finishes
another 3/10
of the problems on her homework after dinner. What fraction of the
problems on her homework does Jessie still have left to do?
Answer: Jessie still has 3/10 left.
Step-by-step explanation:
Convert 2/5 into tenths by multiplying by 2.
2/5 x 2 = 4/10
3/10 + 4/10 = 7/10

Answer: Choice A
Explanation:
The number [tex]\sqrt{8}[/tex] is irrational. We cannot write it as a ratio or fraction of two integers. This is because 8 isn't a perfect square.
Multiplying any irrational number with a rational one leads to an irrational product.

Answer:
The given quadratic has two solutions.
Step-by-step explanation:
The discriminant of a quadratic equation is [(b^2) - (4 * a * c)]
We're given the quadratic x^2 - 8x - 84 = 0
We can find a, b, and c by analyzing the quadratic.
So,
a = 1 because x^2 has no coeffiecient
b = -8 ( coefficient of 8 * the - )
c = -84 the raw y-intercept value of this function
Now we can plug these numbers into the discriminant expression:
(-8)^2 - ( 4 * 1 * -84 ) =
64 - ( - 336 ) =
64 + 336 =
400
Now that we know the value of the discriminant, we have to anazlyze it.
If the discriminant of a quadratic is positive, the quadratic has 2 solutions.
If the discriminant is negative, the quadratic has no solutions.
If the discriminant is equal to zero, the quadratic only has 1 solution.
In conclusion, because the discriminant = 400, and 400 > 0, the given quadratic equation has two solutions.

Answer:
g(x) = 10(x +1)² +5
Step-by-step explanation:
When a point is translated 3 units down, its y-value is 3 less than it was. The graph of f(x) is translated 3 units down by subtracting 3 from the value of f(x).
g(x) = f(x) -3 . . . . . translates f(x) 3 units down
__
For f(x) = 10(x +1)² +8, we want ...
g(x) = f(x) -3 = (10(x +1)² +8) -3
g(x) = 10(x +1)² +5
Translation of 3units down means change in y axis
y is decreased by 3
Hence new equation
g(x)=10(x+1)²+8-3g(x)=10(x+1)²+5What of the following functions is graphed below?
Answer:
Your answer is D. y = |x + 3| - 4
Step-by-step explanation:
Looking at the graph there seems to be only translations shift. There is no vertical stretch/shrink or Horizontal stretch/shrink
Absolute formula: y = |x - h| + k
Your (h,k) = (-3, -4) plug them into the absolute formula.
y = |x - (-3)| + (-4)
y = |x + 3| - 4

Explanation:
The Great Divide commonly refers to the continental divide of North America. The watersheds of the Pacific Ocean are separated from the Atlantic Ocean by the Great Divide. Green River watershed is located to the west of the endorheic basin, and it is drained to the Gulf of California/Pacific Ocean.
The water flowing to the Pacific Ocean is separated from the water flowing to the Southern and Indian Oceans. Various
water sheds can be efficiently fed through Great Divide.
The water is gathered and depleted into water bodies like waterway, lake or stream correct answer is option C i.e. They flow into the same drainage basin.

The front of the stage, side C, is 50 feet long. A 40-foot rope runs along the side of square B. A 30-foot rope runs along the side of square A. Is the roped off area, triangle ABC, a right triangle? Explain. (2 points)
e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning. (2 points)
Answer:
ΔABC is a right triangle
length of the concession stand = 42.4 ft (nearest tenth)
Step-by-step explanation:
Given:
Side length of square A = 30 ftSide length of square B = 40 ftSide length of square C = 50 ftWe can use Pythagoras' Theorem to prove if ΔABC is a right triangle.
Pythagoras' Theorem: a² + b² = c² (where a and b are the legs, and c is the hypotenuse of a right triangle)
Given:
a = side length of square A = 30b = side length of square B = 40c = side length of square C = 50⇒ a² + b² = c²
⇒ 30² + 40² = 50²
⇒ 900 + 1600 = 2500
⇒ 2500 = 2500
Therefore, ΔABC is a right triangle
To find the diagonal of square A, use Pythagoras' Theorem:
Given:
a = side length of square A = 30b = side length of square A = 30c = diagonal of square A⇒ a² + b² = c²
⇒ 30² + 30² = c²
⇒ 900 + 900 = c²
⇒ c² = 1800
⇒ c = √(1800)
⇒ c = 42.42640687
Therefore, the length of the concession stand (diagonal of square A) is 42.4 ft (nearest tenth)

Students at a school will sell hats to raise money. There are some hats left over from last year, and 20 boxes of hats will be ordered this year. When the order arrives, the total number of hats the student will have can be determined using the function f(x) = 48x + 37, where x represents the number of boxes ordered. If the number of hats per box changes so that the situation is modeled by the function h(x) = 24x + 37, then how many fewer hats will the students have available to sell if they still order 20 boxes?
A)517
B)480
C)997
D)365
Answer: A) 480
Step-by-step explanation:
x=20 substitute in the two equations
48(20)+37
24(20)+37
since the question said fewer , then you should subtract
48(20)+37 - 24(20)+37 = (960+37) - (480+37)
=923 - 443= 480
Students will have 517 hats to sell, that is 480 fewer than determined.
The correct option is B.
What is linear equation?A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line.
Given,
Total hats = Left hats of last year + 20 boxes of hats newly ordered
Total hats
f(x) = 48x + 37
where x is number of boxes
But number of hats per box changes,
h(x) = 24x + 37
fewer no. of hats than determined
f(x) - h(x) = 48x + 37 - 24x - 37
f(x) - h(x) = 24x
No. of boxes = 20
No. of hats fewer than determined = 24 × 20 = 480
And no. of hats available
h(20) = 480 + 37
h(20) = 517
No. of hats available to sell = 517
Hence, 517 hats are available to sell that is 480 fewer hats than determined

The average of the test scores of a
group of x students is 76 and the average of the test scores of a group of y students is 90. When the scores of the two groups of students are combined, the average test score is 85. What is the value of x/y
Answer:
x/y = 5/9
Step-by-step explanation:
sum = count * mean
for the group of x students:
sum = x * 76
let's say this sum is a
a = 76x
for the group of y students:
sum = y * 90
let's say this sum is b
b = 90y
total sum = total count * total mean
total sum = total sum from both groups = a + b
total count = total count from both groups = x + y
a + b = (x+y) * 85
expand
a + b = 85x + 85y
a = 76x
b = 90y
replace a with 76x and b with 90y in the first equation. this limits the equation to x and y, which we want because we want to find x/y
76x + 90y = 85x + 85y
subtract 76x and 85y from both sides to limit the amount of numbers
5y = 9x
divide both sides by 9 to isolate the x
(5/9)y = x
divide both sides by y to get x/y
x/y = 5/9

It is said that once a Chinese emperor decided to divide a number of horses among his generals such that
(a) if they are divided equally among 3 of his generals, 2 horses will remain;
(b) if they are divided equally among 5 of his generals, 1 horse will remain;
(c) and if they are divided equally among 7 of his generals, 6 horses will remain.
I. Find the smallest number of horses that satisfies this condition.
II. Write an explicit rule for each of part (a), (b) and (c).
III. Write an explicit rule for the number of horses that can be divided in such a way.
IV. Write a recursive rule for the explicit rule found in part III.
Using the three conditions, the smallest number of horses that can be shared among the generals is 41
The smallest number of horsesThe conditions are given as:
A remainder of 2, if divided among 3 generalsA remainder of 1, if divided among 5 generalsA remainder of 6, if divided among 7 generalsThe numbers that can divide 5 and leave a remainder of 1 are:
