The two ways of rewritting the fraction are.

6/10 = 60/100

6/10 = 0.6

Here we know that of the trees in a park 6/10 have red leaves. And we want to write that fraction with a 100 as the denominator (the second number of the fraction)

To do so, we can multiply our fraction by 10/10

Notice that the quotient is equal to 1 so it does not change the value of our fraction, then we will get:

(6/10)*(10/10) = 60/100

And the fraction written as a decimal is:

6/10 = 0.6

Chase has to jump 2.67 feet to touch the rim.

The rim of the basketball hoop is 10 feet high, which is equal to 120 inches .

Chase's hand can reach 88 inches high.

To find out how many feet Chase has to jump to touch the rim, we need to subtract his reach from the height of the rim:

120 inches (height of rim) - 88 inches (Chase's reach) = 32 inches

So Chase has to jump 32 inches to touch the rim. To convert this to feet, we can divide by the number of inches in a foot:

32 inches ÷ 12 inches/foot = 2.67 feet

Therefore, Chase has to jump  2.67 feet to touch the rim.

Option B is the actual length of the playground, which is 27 feet.

First, find the scale factor from the drawing to the actual playground. Since the width of the drawing is 2 inches and the actual width is 6 feet, the scale factor is:

6 feet / 2 inches = 3 feet/inch

Next, use this scale factor to find the actual length of the playground. The length in the drawing is 9 inches, so the actual length is:

9 inches x 3 feet/inch = 27 feet

The bond yield is approximately 5.0% to the nearest tenth of a percent.

We have,

To find the total cost of the 10 State Farm bonds, we can multiply the price per bond by the number of bonds:

10 bonds x $99.40 per bond = $994.00

So, we paid $994.00 for the 10 State Farm bonds.

To calculate the amount of interest we will receive each year from the bonds, we can use the following formula:

Interest = Principal x Rate

where:

The principal is the amount invested in the bonds

Rate is the interest rate

In this case, our principal is $994.00 and our rate is 5%, or 0.05 as a decimal.

So, the annual interest we will receive from the bonds is:

Interest = $994.00 x 0.05 = $49.70

So,

We will receive $49.70 in interest each year from the bonds.

To calculate the bond yield, we need to use the following formula:

Bond yield = (Annual interest / Total cost) x 100%

In this case, the annual interest is $49.70 and the total cost is $994.00, so we can plug these values into the formula:

Bond yield = ($49.70 / $994.00) x 100% ≈ 5.0%

Therefore,

The bond yield is approximately 5.0% to the nearest tenth of a percent.

For any matrices A and B, where A is a m x n matrix and B is a n x p matrix, the inequality rank(AB) ≤ min rank(A), rank(B) holds.

To see why this is so, examine the rank of a matrix, which is defined as the matrix's greatest number of linearly independent rows or columns.

In other words, it is the dimension of the vector space covered by the matrix's rows or columns.

When we multiply matrices A and B to obtain AB, we get a matrix with m rows and p columns.

The dot product of a row from A and a column from B yields each element in the matrix.

Because the rows and columns of AB are linear combinations of the rows and columns of A and B, the rank of AB is at most the minimum of the rank of A and the rank of B.

If either A or B has a lower rank than the other, there will be some linear dependency between the rows or columns of one of the matrices, which will carry over to AB. This indicates that AB's rank will be strictly less than the bigger matrix's rank.

The ratio of Student Ambassadors to total Students in Mr. Thompson's class is 1:4.

Ratios and proportions are two fundamental concepts in mathematics that are used to compare quantities and express relationships between them.

A ratio is a comparison of two quantities that are expressed in the same units. Ratios are typically written in the form of "a:b" or "a to b", where a and b are two quantities being compared. For example, the ratio of the number of boys to the number of girls in a class of 20 students might be 3:2, indicating that there are 3 boys for every 2 girls.

A proportion is a statement that two ratios are equal. Proportions are used to solve problems involving ratios by setting up an equation that equates two ratios.

The total number of students in Mr. Thompson's class is 6 + 18 = 24.

The ratio of Student Ambassadors to total Students is 6:24, which can be simplified by dividing both the numerator and denominator by 6 to get 1:4.

Answer:

The equation that shows how the cost of the baby shower, y, depends on the number of guests, x is:

y = 9x + 43

In this equation, x represents the number of guests and y represents the cost of the baby shower. The term 9x represents the cost of food for each guest, multiplied by the number of guests. The term 43 represents the cost of decorations that has already been spent. Therefore, the total cost of the baby shower can be calculated by multiplying the number of guests by the cost of food per guest and adding the cost of decorations that have already been spent.

Answer: y = 9x + 43

Step-by-step explanation: y =  cost of the baby shower

To find the probability that the drug will wear off in less than 200 minutes:

The z-score is (200-240)/40 = -1.

Using a standard normal distribution table or calculator, P(z < -1) = 0.1587. Therefore, the requested probability is P(x < 200) = 0.1587.

To find the probability that the drug will wear off after 220 minutes:
