Answer:

It is $17.

Step-by-step explanation:

Answer:

n = 8, w = 3 and perimeter = 122.83 units.

Step-by-step explanation:

Let the angle M is the angle between the equal sides of isosceles JAM.

So, JM = MA

⇒ 35 = 4n + 3

⇒ 4n = 32

⇒ n = 8 (Answer)

Now, if ∠ J = 14w - 1 and ∠ M = 98°, then

2(14w - 1) + 98 = 180

⇒ 2(14w - 1) = 82

⇒ 14w - 1 = 41

⇒ w = 3 (Answer)

Now, draw a perpendicular bisector on JA from vertex M and it meets JA at P say.

So, Δ MPJ will be a right triangle with ∠ J = (14w - 1) = 41° {Since w = 3}

Hence, [tex]\cos 41 = \frac{JP}{JM} = \frac{JP}{35}[/tex]

⇒ JP = 35 cos 41 = 26.415

So, JA = 2 × JP = 52.83  

So, the perimeter of Δ JAM is = 35 × 2 + 52.83 = 122.83 units (Answer)

Answer:

x = (y/4) - (3/2)

Step-by-step explanation:

y=4x+6  (subtract 6 from both sides)

y - 6 = 4x (divide both sides by 4 and rearrange)

x = (y-6) / 4

x = (y/4) - (6/4)

x = (y/4) - (3/2)

Answer:

The quantity of currency  in the pockets does Stephanie has is 45 nickles and 10 dims  .

Step-by-step explanation:

Given as :

The total amount of money does Stephanie have = $ 3.25

The total money is in the form of nickels and dimes

Let the number of nickels = n

And The number of dims = d

∵ we know that 20 nickles makes 1 dollar

And 10 dimes makes 1 dollar

So , in total of 3.25 dollar the number of dime and nickles be

∵ 20 nickles makes 1 dollar

∴ 45 nickles will makes [tex]\frac{1}{20}[/tex] × 45 dollar

I.e 45 nickles will makes 2.25 dollar

Now, ∵ 10 dimes will make 1 dollar

So, The total number of nickles and dimes satisfying equation

45 nickles + 10 dimes = 2.25 dollar + 1 dollar = 3.25 dollar

Hence The quantity of currency  in the pockets does Stephanie has is 45 nickles and 10 dims  . Answer

Answer:

5 meters/second

Step-by-step explanation:

100meters/20 seconds gives the average of 5 m/s

Final answer:

The runner's speed in the hundred meter race completed in 20 seconds is 5 meters per second. To calculate this, divide the total distance (100 meters) by the total time (20 seconds).

Explanation:

To calculate the speed of the runner in meters per second, we divide the distance travelled by the time it took to complete that distance. In this case, the runner completed a 100 meter race in 20 seconds. Using the formula speed = distance/time, we find that the speed is 100 meters / 20 seconds = 5 meters per second.

If the sprinter accelerates for the first 20 meters and then maintains that speed for the remainder of the 100-meter dash, we must first calculate the acceleration period's average speed. As it takes 20 seconds to run 100 meters, the speed over those 20 meters is also 5 meters per second. Once the sprinter reaches this speed at 20 meters, he will continue at this constant speed for the remaining 80 meters. Thus, the time to complete the race is the time taken to accelerate for 20 meters plus the time taken to run the remaining 80 meters at 5 m/s.

Bryan has enough to buy skateboard as it will cost $44.94

Step-by-step explanation:

Original price = $70.00

Discount = 40%

Amount of discount = 40% of original price

Amount of discount = [tex]\frac{40}{100}*70[/tex]

Amount of discount = [tex]\frac{2800}{100}[/tex]

Amount of discount = $28

Price after discount = Original price - amount of discount

[tex]Price\ after\ discount=70-28 = $42\\[/tex]

Sales tax = 7% = [tex]\frac{7}{100} = 0.07[/tex]

Sales tax amount = Price after discount (0.07)

[tex]Sales\ tax\ amount= 42(0.07) = $2.94\\[/tex]

Price of skateboard = Price after discount + sales tax

Price of skateboard = 42+2.94 = $44.94

Bryan has enough to buy skateboard as it will cost $44.94

Answer:

3.6875

Step-by-step explanation:

Answer:

3.6875

Step-by-step explanation:

First, let's leave 3 alone since its a whole number. So now we're dividing the actual fraction. Remember that the top dog goes under, which means that the place where the numerator goes is where the dividend should be, and the denominator is where the divisor should be. Add a decimal point and then after that a few zeros to the 11. Divide like a decimal. You should get 0.6875. Now take that 3 that we left alone before and add it, so you should get 3.6875.

Given equation:  p - -3 7/9 = 5/6

When you subtract a negative number you automatically change it to adding a positive number.

p - -3 7/9 = 5/6 → p + 3 7/9 = 5/6

To isolate p in this equation we need to subtract 3 7/9 to both sides.

p + 3 7/9 - 3 7/9 = 5/6 - 3 7/9

p = -161/18

A total of 750 students responded yes.

As it is given in the tree diagram that is lower there was a total of 450 students who responded yes.

Now, in upper there were a total of 400 students of which 100 students responded no which means (400-100), students responded yes i.e., a total of 300 students responded yes.

So,  upper+lower responses of yes will be total responses of students as yes.

So, a total of 300+450=750  students responded yes.

Hence, 750 students responded yes.

Therefore, option C is the correct answer.

Answer:

The correct graph is attached below.

Step-by-step explanation:

Given:

Initial temperature is 0°.

Decrease in temperature per hour is 12°.

Since, the initial temperature is 0°, the line must pass through the origin as temperature is plotted along the y-axis.

Also, decrease in temperature per hour is 12°. So, this represents the slope of the line. So, the slope should be -12 as there is decrease in temperature with increasing time.

So, the correct graph will be a line passing through origin and the slope of the line must be -12. Also, the temperatures will be along the negative y-axis as the values are decreasing with time.

Hence, the third graph is the correct one and is shown below.

The measure of the angle 1 for the given figure is 61 degree.

Hence the correct option is (A).

From the given figure we have two parallel lines and a transversal which intersects them.

The 119 degree angle and the angle above the angle 1 are corresponding angles, so they are equal.

And the angle above angle numbered 1 and the angle numbered 1 are straight line angles, so the sum of them is 180 degrees.

119 + angle 1 = 180

angle 1 = 180 - 119

angle 1 = 61

Hence the measure of the angle 1 for the given figure is 61 degree.

Hence the correct option is (A).

B) 16x+11/4 =4x+5-2

Step-by-step explanation:

the equation that has no solution is B)[tex]\( \frac{16x + 11}{4} = 4x + 5 \).[/tex]

The correct option is (B).

To find out which equation has no solution, let's solve each equation and see if any leads to a contradiction.

A)[tex]\( \frac{10x + 5}{2} = 3x + 6 \)[/tex]

  Multiply both sides by 2 to eliminate the fraction:

[tex]\( 10x + 5 = 6x + 12 \)[/tex]

  Subtract (6x) from both sides:

[tex]\( 4x + 5 = 12 \)[/tex]

  Subtract 5 from both sides:

  ( 4x = 7 )

  Divide both sides by 4:

[tex]\( x = \frac{7}{4} \)[/tex]

B) [tex]\( \frac{16x + 11}{4} = 4x + 5 \)[/tex]

  Multiply both sides by 4:

[tex]\( 16x + 11 = 16x + 20 \)[/tex]

  Subtract (16x) from both sides:

  ( 11 = 20 ) - Contradiction

C) [tex]\( \frac{8 - 6x}{4} = 4 + 2x \)[/tex]

  Multiply both sides by 4:

  [tex]\( 8 - 6x = 16 + 8x \)[/tex]

  Subtract 8 from both sides:

[tex]\( -6x = 8x + 8 \)[/tex]

[tex]\( -6x = 8x + 8 \)[/tex]

[tex]\( 0 = 14x + 8 \)[/tex] - Contradiction

D)[tex]\( \frac{18x - 10}{2} = 9x - 5 \)[/tex]

  Multiply both sides by 2:

 [tex]\( 18x - 10 = 18x - 10 \)[/tex] - No contradiction, the equation holds true for all ( x ).

So, the equation that has no solution is B)[tex]\( \frac{16x + 11}{4} = 4x + 5 \).[/tex]

Answer:

C = 35 + 45h

In the equation above $35 is the initial value which interprets the cost for motor parts and $45/hour is the rate of charge of the mechanic per hour.

Step-by-step explanation:

Charges for parts and $45 per hour for  labor that takes a mechanic for maintenance of a car.

It costs $125 as Terri spent 2 hours for car maintenance.

Since the function is linear, so we can write  

125 = 45 × 2 + x {Where x is the charges for parts}

⇒ x = 35

Therefore, the equation that models the situation is given by  

C = 35 + 45h ......... (1)

where C is the total cost and h is the number of hours.

Here, in equation (1) $35 is the initial value that interprets the cost for parts and $45/hour is the rate of charge of the mechanic per hour. (Answer)

Answer: Damien has 21 red pieces

Step-by-step explanation:

First, 7/8 of the rectangle is coloured red.

Then, the 7/8 was cut into a size 1/24 of the rectangle each.

That consequently means that 24 of those pieces will form the whole shape.

Since red covers 7/8 of the rectangle, the number of red pieces invariably becomes

⅞ × 24 pieces, which is equal to 21 pieces

Therefore, Damien has cut the red part of the rectangle into 21 pieces

Final answer:

Damien has 21 red pieces after dividing the red part of the rectangle, which is 7/8, into pieces that are each 1/24 of the whole rectangle.

Explanation:

To find the number of red pieces Damien has, we first determine the fraction of the rectangle that is colored red, which is 7/8. Then, we find the size of each piece that Damien cuts, which is 1/24 of the whole rectangle.

Since each piece is 1/24, and Damien is cutting up only the red part which is 7/8 of the whole, we calculate the number of pieces by dividing the red part by the size of each piece: number of red pieces = (7/8) / (1/24).

To do this division, we multiply by the reciprocal of the divisor: (7/8) * (24/1) = 21. Therefore, Damien has 21 red pieces.
