A rectangle has length 3x^2-5x+1 and width x^2-4. Which expression represents the perimeter of the rectangle? Image shows the options.

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.

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.

Hence, 3.89 minutes for the eight graders.

The seventh graders would earn the points instead and awarded 40 points.

Explanation:

Angle 3 and the 100 degree angle are corresponding angles. They are both in the southeast quadrant of their four-corner angle configuration. Assuming the lines that look horizontal are parallel, this would mean angle 3 is 100 degrees. Recall that corresponding angles are congruent when we have parallel lines.

Once we know that angle 3 = 100, we will use this to find angle 4.

Angles 3 and 4 add to 180. They form a straight angle or straight line.

(angle3)+(angle4) = 180

(100) + (angle4) = 180

angle4 = 180-100

angle4 = 80 degrees

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.

Answer:

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]

[tex]Old\ Price= 3750[/tex]

Hence, the current price is Tk. 3750

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

Step-by-step explanation:

Diameter = 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:

Area of each triangle is:

So the shaded area is:

Since 100π is the area of circle, the shaded area is:

Correct choice is D

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]

Step-by-step explanation:

Given:

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.

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.
