1/2
5 1/2
1 1/2

Answer: 118%

Step-by-step explanation:

Cora's kitten weighed in the last visit to the veterinarian's office=550 grams

Right now, Cora's kitten weighs =1200 grams

Increase in the kitten's weight=[tex]1200-550=650\text{ grams}[/tex]

Percent increase in weight=[tex]\frac{650}{550}\times100[/tex]

[tex]=118.18\%\approx118\%[/tex]

Hence, there is 118% increase in kitten's weight.

Answer:

-144ft

Step-by-step explanation:

To create a line of 123 ³/₄ inches with straws each measuring 4 ¹/₈ inches, 30 straws are needed. The cost to make these straws is $0.45.

To determine how many straws are in the line that extends 123 ³/₄ inches using straws that are each 4 ¹/₈ inches long, you would divide the total length of the line by the length of one straw. Converting to improper fractions for ease of calculation, we get:

Dividing the total length by the length of one straw:

Next, to find the total cost of the straws:

Therefore, 30 straws are used to create the line and the total cost for these straws is $0.45.

The height of the rectangular prism chest is approximately  34.93 units, calculated using the volume and base area formulas for rectangular prisms.

To find the height of the rectangular prism chest, we can use the formula for the volume of a rectangular prism, which is given by the product of its length, width, and height. Let's denote the height of the chest as h the length as l , and the width as w.

Given that the volume of the chest is 524 cubic units and the base area (length times width) is 15  square units, we have two equations:

1. [tex]\( l \times w \) (base area) \( = 15 \)[/tex] square units,

2. [tex]\( l \times w \times h \) (volume) \( = 524[/tex]) cubic units.

From the first equation, we can solve for one variable in terms of the other. Let's solve for l  in terms of w :

[tex]\[ l = \frac{15}{w} \][/tex]

Now substitute this expression for l into the second equation:

[tex]\[ \frac{15}{w} \times w \times h = 524 \][/tex]

Simplify:

15h = 524

Solve for h:

[tex]\[ h = \frac{524}{15} \][/tex]

h ≈ 34.93

So, the height of the chest is approximately  34.93  units.

Final answer:

The best estimate of the solution to the system of equations is (1, 5).

Explanation:

In order to find the best estimate of the solution to the system of equations graphed on a coordinate plane, we need to look for the point where the two lines intersect. This point represents the solution to the system of equations.

The coordinates (1, 5) are the best estimate of the solution to the system of equations.

Answer:

82.125 million tons

Step-by-step explanation:

The U.S. produces 36.5 million tons of fruit each year.

To calculate the amount of fruits It produces in 2.25 years we multiply the production of 1 year to 2.25 years.

It produces fruits in 2.25 years = 36.5 × 2.25

                                                   = 82.125 million tons

The U.S. produces 82.125 million tons of fruit in 2.25 years.

Answer:

Brown rice

Step-by-step explanation:

We must determined how much you pay per oz. for each type of rice to determine the best buy.

For brown rice:

[tex]79/16=4.93[/tex]

You pay approximately 5 cent per oz. of brown rice.

For white rice:

[tex]3.49/32=0.109=0.11[/tex]

You pay 11 cents per oz. of white rice.

White rice is twice the price of brown rice per oz.

∴ brown rice

Using division and a visual method, it is calculated that Gina has 71 quarters, given she has a total of $17.75.

Gina has $17.75 and since each quarter is worth $0.25, we need to find out how many quarters make up this amount. First, using division we have 17.75 ÷ 0.25 = 71. Therefore, Gina has 71 quarters.

The second method is a more visual and explanatory one. Since each quarter is 25 cents, four quarters make up a dollar. Therefore, if we have $17, that directly translates to 17 x 4 = 68 quarters. We also have 75 cents left which correspond to another 3 quarters (75 ÷ 25 = 3). Adding these together gives us 68 + 3 = 71 quarters. So, either way, Gina has 71 quarters.

To show what part of an hour has passed using 3 equivalent fractions, we use the position of the hour hand relative to the clock's 12-hour cycle. For instance, if the hour hand is at 3, 1/4 of an hour has passed, which can be shown as 1/4, 2/8, or 3/12.

To label each clock with at least 3 equivalent fractions to show what part of an hour has passed, we would typically look at how much of the 12-hour cycle of the clock has been covered. For example, if the hour hand is pointing at the 3, a quarter of the cycle has passed, because 3 out of 12 hours have elapsed. Therefore, the equivalent fractions representing this time segment could be 1/4, 2/8, and 3/12. The idea here is that each fraction must have a numerator and denominator, which, when simplified, would result in 1/4.

More examples include if the hour hand points at 6, half of the clock or an hour has passed, hence equivalent fractions could be 1/2, 4/8, and 6/12. If it's at the 9, three-fourths of the clock has passed, so equivalent fractions could be 3/4, 6/8, and 9/12. Understanding time conversion between words and numbers and basic fractions is crucial to identifying these equivalent fractions on an analog clock.

The correct option is c.

The volume of a cylinder with a radius of 6 units and a height of 8 units is approximately 904.32 cubic units when using π as 3.14 in the formula, and is exactly 864 cubic units when using π as 3 in the formula.

The given question is based on the formula to calculate the volume of a cylinder. The formula is V = πr²h where V is the volume, r is the radius of the base, h is the height of the cylinder, and π (Pi) is approximately equal to 3.14.

In this case, r = 6 units and h = 8 units. Now, substituting these values into the formula:

V = π * (6 units)² * 8 units = 3.14 * 36 sq.units * 8 units = 904.32 cubic units

The available options don't include this value, but keep in mind that π is typically approximated in school-level problems, which might account for a slight variance in the final answer.

If π is approximated to 3 (instead of 3.14), the volume would be 3 * 36 * 8 = 864 cubic units.

Final answer:

To find the necessary increase in wind speed for Tropical Storm Hamm to reach hurricane status, set up the inequality 42 + x >= 74, resulting in x >= 32. Hence, the wind speed must increase by at least 32 miles per hour.

Explanation:

To determine how much the wind speed must increase for Tropical Storm Hamm to become a hurricane, we use an inequality. We know that a storm becomes a hurricane when the wind speeds reach at least 74 miles per hour.

Currently, Tropical Storm Hamm has wind speeds of 42 miles per hour. Let's define the variable x as the increase in wind speed needed for the storm to reach hurricane status.

The inequality that represents this situation is:
42 + x ≥ 74

Now, we solve for x:

Subtract 42 from both sides of the inequality: x ≥ 74 - 42

Simplify: x ≥ 32

Therefore, the wind speed must increase by at least 32 miles per hour for Tropical Storm Hamm to become a hurricane.
