I need some help answering this math question

Answer:

The cost of one cricket bat is $370, while the cost of one cricket ball is $185.

Step-by-step explanation:

Let's identify what we already know:

1) Mr. Lenny paid a TOTAL of $1480.00 for 4 cricket balls, and two cricket bats.

2) The cost of one cricket bat is twice as much as a cricket ball.

We can create an initial equation:

(4 times x) + (2 times y) = $1480.00

x is the price of one cricket ball, while y is the price of one cricket bat. Considering how the problem is set up, I know the 4 balls should add up to the same price as two bats.

So, the four balls should equal half of $1480, which is $740, and the two bats should also equal $740.

Calculate it out, and you'll find that one cricket bat equals $370, while one ball equals $185.

The question can be solved by representing the cost of a ball as x and bat as 2x, forming the equation 4x + 2(2x) = 1480. Solving this equation finds the cost of the individual cricket ball and bat.

In this question, we know that the cost of one cricket bat is twice the cost of a cricket ball, and that Mr. Lenny bought 4 cricket balls and 2 cricket bats for $1480.00. To solve for the individual price of each item, we can use the method of substitution in algebra.

Let's represent the cost of a ball as x and a bat as 2x. This becomes an equation of 4x (cost of 4 balls) + 2(2x) (cost of 2 bats) = 1480.

Solving for x will give us the cost of one cricket ball, and multiplying the value of x by 2 will offer the cost of a single cricket bat.

Answer:

9 x⁶y⁴

Step-by-step explanation:

for a rectangle

area = length x width, (rearranging)

width = area / length

given area = 54x⁹y⁸ and length = 6x³y⁴

width = 54x⁹y⁸ / 6x³y⁴

= (54/6) ( x⁹y⁸ / x³y⁴)

= 9 ( x⁹y⁸ / x³y⁴)

= 9 ( x⁹⁻³y⁸⁻⁴ )

= 9 ( x⁶y⁴ )

= 9 x⁶y⁴

The expression represents the width of the rectangle in yards is 9 x⁶y⁴.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

For a rectangle

width = area / length

The given area = 54x⁹y⁸ and length = 6x³y⁴

width = 54x⁹y⁸ / 6x³y⁴

= (54/6) ( x⁹y⁸ / x³y⁴)

= 9 ( x⁹y⁸ / x³y⁴)

= 9 ( x⁹⁻³y⁸⁻⁴ )

= 9 ( x⁶y⁴ )

= 9 x⁶y⁴

Hence, the expression represents the width of the rectangle in yards is 9 x⁶y⁴.

Answer:

She will have 252 seeds left.

Step-by-step explanation:

12 x 42 = 504

504 ÷ 2 = 252

So, she will have planted 252 seeds and she will have 252 seeds left to plant.

Final answer:

Julia has 252 seeds left after planting half of the seeds.

Explanation:

To find out how many seeds Julia has left, we first need to determine the total number of seeds she has. Julia bought 12 bags of cucumber seeds, and each bag contains 42 seeds. So the total number of seeds she has is 12 bags × 42 seeds per bag = 504 seeds.

If Julia plants one-half of the seeds, she would be planting 504 seeds × 1/2 = 252 seeds.

To find out how many seeds she has left, we subtract the number of seeds she planted from the total number of seeds she initially had. 504 seeds - 252 seeds = 252 seeds left.

Answer:

False

Step-by-step explanation:

According to the The Triangle Inequality Theorem, the sum of any two sides of a triangle must be greater then the measure of the third side. So use this theorem to solve:

6+12=18 and 18>5

so far it is following the theorem but we need to make sure all of the sides follow it so lets continue.

6+5= 11 and 11<12

This does not follow the theorem, so the sides 5,6, and 12 cannot form a triangle.

The associations that best describe the scatter plot are: C. Negative association A. linear association

On a scatter plot, if one variable increases or decreases as the other increases or decreases, it shows a positive association.

On the other hand, if one variable increases as the other decreases, it is a negative association.

Also, if the points are along a straight line, the association is linear.

Thus, in the scatter plot given, as time increases, distance decreases.

Therefore, the associations that best describe the scatter plot are: C. negative association A. linear association

percentage, a relative value indicating hundredth parts of any quantity.

Given that a  basketball player made 17 out of 20 free throws at practice

We need to find the percent of the free throws did the player miss.

We find this by finding the product of x/100 with 20 which is equal to 17.

x/100 × 20=17

Now we have to find the value of x which is the percentage.

2x/10=17

0.2x=17

Divide both sides by 0.2

x=17/0.2

x=85%

Hence, if a basketball player made 17 out of 20 free throws at practice then 85% of the  free throws did the player miss.

The absolute value function y = 6 |x - 3| can be written as a piecewise function. For x < 3, y = 6 * (3 - x) and for x >= 3, y = 6 * (x - 3). This takes into account the always-positive relationship of the absolute value function.

The absolute value function y = 6 |x - 3| can be written as a piecewise function as follows:

This is because the absolute value function defines a relationship where distance is always positive. For values of x less than 3, the expression within the absolute value brackets is negative, so we have to change the sign. For values of x greater than or equal to 3, the expression is already positive, so it stays as it is.
