The time taken is 52.5 seconds to assemble 20 pizza boxes if the fastest pizza box folder can assemble 8 pizza boxes in 21 seconds.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

The fastest pizza box folder can assemble 8 pizza boxes in 21 seconds.

The rate of assemble = 21/8 seconds per pizza

The time is taken to assemble 20 pizza boxes:

= (21/8)x20

= 420/8

= 52.5 seconds

Thus, the time taken is 52.5 seconds to assemble 20 pizza boxes if the fastest pizza box folder can assemble 8 pizza boxes in 21 seconds.

The ladder were too short or too long  is p

If the ladder was too short you wouldn’t be able to get to the place you need the ladder for.

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangle triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.

If the ladder was too long you have a high chance of falling and being too high to reach where you’re trying to go.

Answer:

1. Right: pointing downwards

Left: pointing upwards

2. Right: pointing upwards

Left: pointing upwards

3. Right: pointing downwards

Left: pointing upwards

4a. True

4b. True

Step-by-step explanation:

When the leading coefficient is negative the equation will either open downwards or the y-values will decrease as the x-values increase. The opposite is true for when the leading coefficient is positive. When the degree is odd one end will point downwards while the other points upwards. When the degree is even, both ends point in the same direction.

Step-by-step explanation:

Avery is correct because adding 2 to the graph of a function will shift it upward, while subtracting will shift it downward. Cindy is also correct because the point on the x axis also changes, would mean that every point also changes horizontally.

Answer:

st=pq su=rp and for the other ones angle q is 75 degrees so just add 59 and 75 then subtract it from 180 because that's how many degrees is in a triangle and angle s is 59

[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]

Both triangles are congruent, Hence Angles of both triangle will be equal,

We have got two angles,

LP = 59°, LT = 75°

let the third angle be x

The sum of all angles of a triangle is 180°

So,

59° + 75° + x = 180

x = 46°

a) ST = 8m

b) SU = 7m

c) mLR = 75°

d) mLQ = 46°

e) mLS = 59°

Based on the amount that you bid and its percentage out of what you would pay, the amount that you were willing to pay more was $15

The winning bid of $35 is only 70% of what you would have paid at most.

Your maximum bid would therefore have been:

= 35 / 70%

= $50

The amount that you were then willing to pay more than your bid was:

= Maximum bid - Winning bid

= 50 - 35

= $15

In conclusion, you were willing to pay $15 more.

Step-by-step explanation:

Answer:

3a^2 - 6b + 2ab

Step-by-step explanation:

Put all the like terms together

(4a^2 - a^2) - (7b + b) + 2ab

then simplify

(4a^2 - a^2) = 3a^2

(-7b + b) = -6b

then rewrite

3a^2 - 6b + 2ab

Answer:

3a^2 - 6b + 2ab

Step-by-step explanation:

Add like terms together so shifting the equation a little to make it easier to add:

4a^2 - 7b + 2ab - a^2 + b

4a^2 - a^2 - 7b + b + 2ab

3a^2 - 6b + 2ab

Answer:

After the reflection over the line  y = -x, the image of the point is: (-3,-2)

Step-by-step explanation:

When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.

Let (x,y) be a point on the plane

and

y = -x be a line on the plane

When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated

So (x,y) will become (-y,-x)

Given point is:

(2,3)

After the reflection over the line  y = -x, the image of the point is: (-3,-2)

40*40%= 16

16 is the difference between the 40 and 56.

The percentage increase in the speed of the car from 40 km per hour to 56 km per hour will be 71.43%.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A car is travelling at 40 kilometres per hour.

The car increases its speed to 56 kilometres per hour.

Then the percentage increase in the speed of the car will be

[tex]\rm P = \dfrac{40}{56} \times 100\\\\P = 71.4285\% \approx 71.43\%[/tex]

Answer: 1/6

Step-by-step explanation:

A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.

Odd numbers in a die = 1, 3 and 6

Numbers greater than 4 = 5 and 6

Probability of rolling an odd number = 3/6 = 1/2

Probability of rolling a number greater than 4 = 2/6 = 1/3

We then multiply both values gotten. This will be:

= 1/2 × 1/3

= 1/6

Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.

The probability of rolling an  odd number the first time and a number greater than 4 the second time is 1/6

The sample space of a single die is

[tex]\mathbf{S = \{1,2,3,4,5,6\}}[/tex]

So, the total sample is 6

The odd numbers are

[tex]\mathbf{Odd = \{1,3,5\}}[/tex] --- 3 odd numbers.

So, the probability of selecting an odd number is:

[tex]\mathbf{P(Odd) = \frac 36}[/tex]

Simplify

[tex]\mathbf{P(Odd) = \frac 12}[/tex]

The numbers greater than 4 are

[tex]\mathbf{Greater = \{5,6\}}[/tex] --- 2 numbers greater than 4.

So, the probability of selecting a number greater than 4 is:

[tex]\mathbf{P(Greater) = \frac 26}[/tex]

Simplify

[tex]\mathbf{P(Greater) = \frac 13}[/tex]

The probability of rolling an  odd number the first time and a number greater than 4 the second time is calculated as follows:

[tex]\mathbf{P = P(Odd) \times P(Greater)}[/tex]

So, we have:

[tex]\mathbf{P = \frac 12 \times \frac 13}[/tex]

[tex]\mathbf{P = \frac 16}[/tex]

Hence, the probability is 1/6
