If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?
Answer:
The answer for the first part would be 3.89 minutes for the eight graders. There are 60 seconds in one minute so you’d have to take away 29 and add it to the full 4 minutes, which makes the 8th graders best time for the race 4.29 minutes. That’s more than 4 minutes, so the seventh graders would earn the points instead.
Step-by-step explanation:
The seventh graders would earn the points instead and awarded 40 points.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We are given that If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points.
If not, the seventh graders earn 40 points.
There are 60 seconds in one minute so, we have to take away 29 and add it to the full 4 minutes, which makes the 8th graders best time for the race 4.29 minutes.
That’s more than 4 minutes, therefore, the seventh graders would earn the points instead.

Help will give braniest answer to person who is correct find the degree measure of each angle in the triangle
Answer:
Angle I = 90 degrees
Angle J = 61 degrees
Angle K = 29 degrees
Step-by-step explanation:
Angle I is given
We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:
(5x+26) + (2x+15) = 90
Solve for X:
7x + 41 = 90
7x = 49
x = 7
Angle J = (5x + 26) = (5(7) + 26) = 61
Angle K = (2x + 15) = (2(7) + 15) = 29
Checking your work: 61 + 29 = 90
Answer:
[tex] m\angle I = 90\degree [/tex]
[tex] m\angle J= 61\degree [/tex]
[tex] m\angle K = 29\degree [/tex]
Step-by-step explanation:
(5x + 26)° + (2x + 15)° = 90°
(5x + 26 + 2x + 15)° = 90°
(7x + 41)° = 90°
7x + 41 = 90
7x = 90 - 41
7x = 49
x = 49/7
x = 7
[tex]m \angle \: I= 90 \degree \\ \\ m \angle \: J=(5x + 26) \degree = (5 \times 7 + 26) \degree \\ \\ m \angle \: J = (35+ 26) \degree \\ \\ m \angle \: J= 61\degree\\ \\ m \angle \: K=(2x + 15) \degree = (2 \times 7 + 15) \degree \\ \\ m \angle \: K = (14+ 15) \degree \\ \\ m \angle \: K = 29\degree[/tex]

Five members of the Varsity Math team are running late for a big
competition and hurrying toward the arena - but they forgot that they would
have to cross the stream that cuts through campus. When they reach the
stream, there's a small boat tied up on their side that they can "borrow” to get
to the other side.
The boat will hold one, two or three of the students, but not more.
Fortunately, two of the team members are also on the crew team, and when
the boat contains only one or both of them, they can make it across the stream
in one minute. Unfortunately, the other three teammates are very
inexperienced with boats, and when any of them is aboard, there is so much
awkwardness and flailing that the crossing will take four minutes, regardless
of whether one of the crew teammates is on board.
Answer: What is the question?
find the measure of BEK
Step-by-step explanation:
Angles BEC and KEC are labelled as congruent.
Therefore (6x + 24)° = 10x°, 4x = 24, x = 6.
Hence Angle BEK = (6x + 20)° + 10x°
= (16x + 24)° = 16(6) + 24 = 120°. (C)
The value of ∠BEK will be 120° so option (C) will be correct.
What is congruence?
If two figures are exactly the same in sense of their length side all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
In other meaning, if you can copy a figure then that copy and the original figure will be congruent.
Given figure has two triangles ΔCBE and ΔCKE.
The angle of (6x + 24)° is the same as (10x)° ( given congruency of angle by double line)
So,
6x + 24 = 10x
10x - 6x = 24
4x = 24
x = 6°
So,
Angle ∠BEK
∠BEK = (6x + 24) + (10x)
∠BEK = 6(6) + 24 + 10(6)
∠BEK = 120°.
Hence "The value of ∠BEK will be 120° ".

Write the equation of the line in slope-intercept form that goes through the points: (2,4) and (7,-1)
Answer:
y= -x+8
Step-by-step explanation:
slope int. form: y=mx+b
first, we need to find the slope (m)
the two points are (2,4) and (7,-1).
to find the slope we do (y2-y1)/(x2-x1)
doing this we get -5/5=-1
now we can plug in point (2,4) and the slope into y=mx+b
doing this we get:
4=-1(2)+b
4=-2+b
b=8
now we have the equation:
y= -x+8

The price of a share of stock in JZMobile was $74 two weeks ago.
Seven weeks ago, the price was $59 a share.
To find:
The linear equation to find the price p of a share of JZMobile w weeks from now.
Solution:
Let, p be the price of a share of JZMobile w weeks from now.
The price of a share of stock in JZMobile was $74 two weeks ago. It means, the graph of linear equation passes through (2,74).
Seven weeks ago, the price was $59 a share. It means, the graph of linear equation passes through (7,59).
The graph of linear equation passes through two points (2,74) and (7,59). So, the linear equation is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-74=\dfrac{59-74}{7-2}(x-2)[/tex]
[tex]y-74=\dfrac{-15}{5}(x-2)[/tex]
[tex]y-74=-3(x-2)[/tex]
[tex]y-74=-3x+6[/tex]
Adding 74 on both sides, we get
[tex]y=-3x+6+74[/tex]
[tex]y=-3x+80[/tex]
[tex]y=80-3x[/tex]
Therefore, the correct option is C.

Problem 22 is not fully visible with missing detailsProblem 25 is solved onlyDiameter = 20 cm → radius = 10 cm
Each triangle has its side equal to radius = 10 cm
Each shaded region is the difference of area of the sector and triangle
Each sector is 60° as triangles are equilateral
Area of circle is:
πr² = 100πArea of each triangle is:
√3/4a² = √3/4r²= 100×√3/4So the shaded area is:
3(πr²/6 - √3/4a²) = 3(π×10²/6 - √3/4×10²) =100(π/2 - 3√3/4) = 100π(1/2 - 3√3/4π)Since 100π is the area of circle, the shaded area is:
1/2 - 3√3/4π part of area of circle if we divide the shaded area by the area of circle.Correct choice is D

You work delivering food for a local farmer. You sell eggs from the farm at a price of 3 for $2.00, 6 for $3.50, 12 for $6.00, and 24 for $13.00. What is the best deal for buying eggs?
A.
3 eggs for $2
B.
6 eggs for $3.50
C.
12 eggs for $6.00
D.
24 eggs for $13.00
Answer:
The 12 egg offer.
Step-by-step explanation:
Find the unit price for each. Then make them common denominators. Like 3 eggs for 2 dollars is for 1 egg, 2/3 dollars. After getting the unit price for all of them, get the common denominators of 24. Then we see which numerator is the lowerst, since we want the lowerst price. We find 12/24, or the 12 egg offer.

The current price is Tk. 3750
Step-by-step explanation:
Given:
[tex]\%\ Increase = 20\%[/tex]
[tex]New\ Price = Tk.\ 4500[/tex]
Required
Determine the current price
Percentage increment is calculated using the following formula:
[tex]\%\ Increase = \frac{New - Old}{Old}[/tex]
In this case, we have:
[tex]\%\ Increase = \frac{New\ Price - Old\ Price}{Old\ Price}[/tex]
Substitute values for % increase and New Price
[tex]20\% = \frac{4500 - Old\ Price}{Old\ Price}[/tex]
Cross Multiply
[tex]20\% *Old\ Price= 4500 - Old\ Price[/tex]
Convert percentage to decimal
[tex]0.20*Old\ Price= 4500 - Old\ Price[/tex]
Collect Like Terms
[tex]Old\ Price+0.20*Old\ Price= 4500[/tex]
Factorize:
[tex]Old\ Price(1+0.20)= 4500[/tex]
[tex]Old\ Price(1.20)= 4500[/tex]
Solve for Old Price
[tex]Old\ Price= \frac{4500}{1.20}[/tex]

19. Brian bought a new jacket at a discount of 30%. If the original price was $65, how
much did Brian pay for the jacket?
Answer: Brain paid $ 45.5 for the jacket.
Step-by-step explanation:
Given: Original price of jacket = $ 65
Discount -= 30%
Price after discount = Original price - 30% of Original price
= 65 - 30% of 65
= 65 - (0.3) x 65 [30% = 0.3]
= (65) (1-0.3 ) [Taking 65 common]
= (65)(0.7)
= $ 45.5
Hence, Brain paid $ 45.5 for the jacket.
