A lawn had an area of 35 square feet. If it was 7 feet width, how long was it?

Answers

It would be 245. You multiply length x width. 35x 7= 245

When, a lawn had an area of 35 square feet. If it was 7 feet width. Then, the length of the lawn will be 5 feet.

We, can use the area formula for a rectangle, which is area = length x width.

Given the area of the lawn is 35 square feet and the width is 7 feet, we can set up the equation:

Area = Length x Width

35 sq ft = Length x 7 ft

To find the length, you would divide the area by the width:

Length = Area \ Width = 35 sq ft / 7 ft = 5 ft

Therefore, the length of the lawn is 5 feet.

the circumference of a clock is 22 inches . What is the radius of the clock?

Answers

The formula for finding radius is r=c/2π where r is radius, c is circumference and π is pi, c is 22 inches, π is 22/7
r=22/ (2*22/7)=22/ 44/7=7/2=3.5 inches
Therefore the radius is 3.5 inches

Answer: Radius of the clock is 3.5 inches.

Step-by-step explanation:

Since we have given that

Circumference of a clock = 22 inches

We need to find the radius of the clock.

As we know the formula for "Circumference":

[tex]C=2\pi r\\\\22=2\times \frac{22}{7}\times r\\\\\frac{7}{2}=r\\\\r=3.5\ inches[/tex]

Hence, radius of the clock is 3.5 inches.

expression is equivalent to −4.6+(−0.4)+(−7.2)−4.6+(−0.4)+(−7.2) ?

Answers

Final answer:

The expression −4.6+(−0.4)+(−7.2)−4.6+(−0.4)+(−7.2) combines all the like terms for a result of −24.4. You simply add and subtract the negative numbers in pairs and then combine the results.

Explanation:

The mathematical expression in question is −4.6+(−0.4)+(−7.2) −4.6+(−0.4)+(−7.2). This appears to be a straightforward question of addition and subtraction involving negative numbers.

To find the equivalent expression, we can group the like terms and add or subtract them accordingly.

Let's first simplify the expression

−4.6 + (−4.6) = −9.2,−0.4 + (−0.4) = −0.8,(−7.2) + (−7.2) = −14.4.

Now, summing up these results gives us:

−9.2 + (−0.8) + (−14.4) = −9.2 −0.8 −14.4 = −24.4.

The equivalent expression for −4.6+(−0.4)+(−7.2)−4.6+(−0.4)+(−7.2) is simply −24.4.

Explain the proof
------------------------------------
Please help I will mark as the brainleist answer!!!! Thanks for 14 points

Answers

1:8 is the correct answer because 24 divided by 3 is 8.
Final answer:

The ratio of cereal boxes with prizes to without prizes in this scenario is 1:7, which is option A. This is calculated by dividing the number of boxes with and without prizes by the smallest number (3), resulting in the simplified ratio.

Explanation:

The subject of this question is about understanding mathematical ratios, specifically in the context of a cereal box prize scenario. Here, we are asked to find the ratio of boxes with prizes to boxes without prizes. If 3 out of 24 boxes contain a prize, that means 21 boxes are without a prize.

To find the ratio of boxes with prizes to boxes without prizes, we divide both numbers by the smallest one, which is 3, the number of boxes with prizes. Hence, the ratio is 3:21, which simplifies to 1:7 (since both numbers are divisible by 3). Therefore, the answer to this question is Option A, 1:7.
