7/8 of a rectangle is colored red. Damien cuts this red part into a number of pieces so that each piece is 1/24 of the whole rectangle. Find the number of red pieces Damien has.
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.
The length of a rectangle is 7 yd more than double the width, and the area of the rectangle is 99 yd^2. find the dimensions of the rectangle.
Answer:
w(2w+7) = 99
2w^2 + 7w - 99 = 0
( 2w - 11 )(w + 9 ) = 0
w+9=0 results in negative measures
2w-11 = 0
2w = 11
w = 11/2 = 5.5
L = 2w + 7 = 18
To perform car maintenance, a mechanic
charges for parts and $45 an hour for
labor. The total cost that Terri spent for
2 hour of car maintenance is $125.
Assume the relationship is linear. Find
and interpret the rate of change and the
initial value
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)

how do you find x in y=4x+6
Answer:
impossible!
Step-by-step explanation:
There is no solution! 0=0
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:
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]

3. (First picture answer options are the 4 graphs after it.)
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.
Isosceles JAM has convex angle M. JM=35,MA=4n+3, angle J=14w-1, and angle m=98 Find n. Find w. Find the perimeter of JAM
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)

What operation must be done to both sides of the equation to solve for p- -3 7/9 = 5/6?
A) add 5/6. B) subtract 3 7/9. C) subtract 5/6. D) add 3 7/9
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 runner finished the hundred meter race in 20 seconds. What was his speed in meters per second?
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.

two families bought tickets for a game. one family paid $71 for 6 adults and 2 children. another family paid $56.50 for 4 children and 3 adults. how much do the tickets cost.
Answer:
Adult Ticket cost $9.50 and Children Ticket cost $7.00
Step-by-step explanation:
Let single adult tickets cost "a" and single children ticket cost "c"
6 adult and 2 children ticket is $71, we can write:
6a + 2c = 71
Also,
3 adult and 4 children tickets cost $56.50, so we can write:
3a + 4c = 56.5
We multiply 2nd equation by "-2", to get:
-2 * (3a + 4c = 56.5) = -6a -8c = -113
Now we add this equation with 1st and eliminate a and solve for c:
6a + 2c = 71
-6a -8c = -113
-------------------
-6c = -42
c = -42/-6
c = 7
To find a, we can plug this into 1st equation and then get our answer.
6a + 2c = 71
6a + 2(7) = 71
6a + 14 = 71
6a = 57
a = 57/6
a = 9.5
Hence,
Adult Ticket cost $9.50 and Children Ticket cost $7.00

Bryan wants to purchase a skateboard. He has $50 to spend. he finds one that regularly sells for $70.00 and is on sale for 40% off. Sales tax is 7%. Bryan says he has enough money to buy the skateboard. is he correct?
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
