Josh will do more push ups than Charis in 2 1/2 minutes. This can be solved by using the concept of multiplication.

Along with addition, subtraction, and division, multiplication is one of the four fundamental mathematical operations. Multiply in mathematics refers to the continual addition of sets of the same size. One of the fundamental mathematical processes is multiplication. The result of multiplying two or more integers together is known as the product. The first number used in a multiplication operation between two numbers is referred to as the multiplicand.

Given that,

Josh did 36 push ups in 30 seconds

Josh did push ups in 2 1/2 minutes:

= (36/30) × 150

= 180 push ups

Chris did 56 push ups in 50 seconds

Chris did push ups in 2 1/2 minutes:

= (56/50)× 150

= 168 push ups

Thus, Josh will do more push ups than Charis in 2 1/2 minutes.

Step-by-step explanation:

Answer:

8x3 + 2x − 5

Step-by-step explanation:

If Elish was required to write a 600 word Literature essay and word count on her computer showed that she had typed 240 words Elish still needs to complete 3/5 of the essay.

To find the fraction of the essay that Elish still needs to complete, we need to determine how many words she has left to write. We can do this by subtracting the number of words she has already written from the total required word count:

Words left to write = Total word count - Words already written

Words left to write = 600 - 240

Words left to write = 360

Now, to find the fraction of the essay that Elish still needs to complete, we can express the remaining words as a fraction of the total word count:

Fraction of essay left to complete = Words left to write / Total word count

Fraction of essay left to complete = 360 / 600

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 120:

Fraction of essay left to complete = (360 ÷ 120) / (600 ÷ 120)

Fraction of essay left to complete = 3 / 5

This means that she has completed 2/5 of the essay so far (which is the equivalent fraction of 240/600).

In order to guide learners to move from the concrete level to the semi-concrete and finally to the abstract level in relation to their understanding of the more than/less than concept, I would use a step-by-step approach.

At the concrete level, I would introduce the concept of more than/less than with a hands-on activity. For example, I would have students compare the number of counters or blocks and have them determine which group has more or less. This would help them develop a fundamental understanding of the concept.At the semi-concrete level, I would introduce the concept of more than/less than with written numerals. I would have students compare numbers on paper, such as 4 and 6, and have them determine which number is more or less. I would also ask them to use concrete objects to represent the numbers, such as using four counters for 4 and six counters for 6.At the abstract level, I would introduce the concept of more than/less than with larger numbers. I would ask students to compare numbers such as 12 and 15, and determine which number is more or less. I would also ask them to use abstract symbols, such as 12 + and 15 -, to represent the numbers.By using this step-by-step approach, students will be able to move from the concrete level to the semi-concrete and finally to the abstract level of understanding the more than/less than concept. This will help them develop a strong foundation of the concept, which will allow them to solve more complex problems in the future.

The snow on the lawn after 5 hours is 14.50 inches.

The snow on the lawn after tt hours is 12 + 0.5tt inches

The equation that represents the amount of snow after a number of hours is a linear equation. A linear equation is an equation that has a single variable that is raised to the power of one.

The form of the equation is:

Total snow = snow on the lawn + (rate at which the snow falls x number of hours)

Snow after 5 hours = 12 + (0.5 x 5)

= 12 + 2.5 = 14.50 inches

Snow after tt hours = 12 + (0.5 x tt)

= 12 + 0.5tt inches

Answer:

v = 21

Step-by-step explanation:

Suppose v varies directly as g, meaning that there is a constant k such that v = kg. If v = 70 when g = 30, then we can use this information to find the value of k:70 = k * 30k = 70 / 30k = 7 / 3Now that we have the value of k, we can use it to find v when g = 9:v = kgv = (7 / 3) * 9v = 21So when g = 9, v = 21.In conclusion, by finding the value of the constant of proportionality k and using the formula v = kg, we determined that when g = 9, v = 21.

Whole Area = (x + 1 + 1) * (y + 1 + 1)

Whole Area = (x + 2) * (y + 2)

Expand

Whole Area = xy + 2x + 2y + 4

So, the mat area is

Mat area = xy + 2x + 2y + 4 - xy

Mat area = 2x + 2y + 4

The cost is

Cost = 0.05 * (2x + 2y + 4)

Step-by-step explanation:

The shaded region comprises of two same trapeziums:

∴Area of shaded region = 2 × (Area of a trapezium)

    = 2 × [tex]\frac{1}{2}[/tex] × (Sum of parallel sides) × (perpendicular height of trapezium)

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

    = 84 square inches

The expression that represents the area of each section is 14.2z - 9.8.

What is area ?

To find the area of each section, we need to divide the total area of the garden plot by the number of sections, which in this case is six.

The expression for the area of each section can be obtained by dividing the expression for the total area by 6:

(area of each section) = (total area of garden plot) / 6

(area of each section) = (85.2z - 58.8) / 6

Simplifying this expression, we can divide both terms by 6:

(area of each section) = 14.2z - 9.8

Therefore, the expression that represents the area of each section is 14.2z - 9.8.

The false statement is (a) P( A^c n B^c)=P(A^c) P(B^c). The probability of the intersection of complements is generally not equal to the product of individual complements.

The misleading assertion including p, and the erratic occasions An and B is (a) P( A^c n B^c)=P(A^c) P(B^c).

This assertion is bogus in light of the fact that by and large, the likelihood of the convergence of the supplements of two occasions, A^c and B^c, isn't equivalent to the result of their singular supplements.

For instance, assume we flip a fair coin. Let A be the occasion of getting heads and B be the occasion of getting tails. Then, P(A) = P(B) = 1/2, so P(A^c) = P(B^c) = 1/2. In any case, A^c and B^c are a similar occasion (getting heads or tails, separately), so P(A^c n B^c) = P(A^c) = 1/2. Then again, P(A^c) P(B^c) = (1/2)(1/2) = 1/4, which isn't equivalent to P(A^c n B^c).

Answer: To determine which vehicle received the greater force, we need to calculate the momentum change for each vehicle during the collision. The force experienced by a vehicle during a collision is equal to the rate of change of its momentum.

First, let's calculate the initial momentum for each vehicle:

The car has a mass of 1,000 kg and a velocity of 30 m/s, so its initial momentum is 1,000 kg * 30 m/s = 30,000 kg m/s.

The truck has a mass of 2,000 kg and a velocity of 20 m/s, so its initial momentum is 2,000 kg * 20 m/s = 40,000 kg m/s.

Next, let's calculate the final momentum for both vehicles after the collision:

The car and truck collide head-on, so their velocities will become zero after the collision. So the final momentum for both vehicles will be zero.

Finally, we can calculate the rate of change of momentum for each vehicle:

The rate of change of momentum for the car is equal to its final momentum minus its initial momentum, or 30,000 kg m/s - 0 kg m/s = 30,000 kg m/s.

The rate of change of momentum for the truck is equal to its final momentum minus its initial momentum, or 0 kg m/s - 40,000 kg m/s = -40,000 kg m/s.

Since the magnitude of the rate of change of momentum for the truck is greater than the magnitude of the rate of change of momentum for the car, the truck has received the greater force.

The solution of the system of equations is (4, 3)

Here we want to solve the system below:

8x+2y=38

2x-4y=-4

If we add 2 times the first equation and the second equation we will get:

2*(8x + 2y) + (2x - 4y) = 2*38 - 4

16x + 4y + 2x - 4y = 72

18x = 72

x = 72/18  = 4

And the vale of y is given by inputing x = 4 in one of the two equations.
