I’m not sure about this question. Please help thanks!

The answer will be 1.53 after dividing and rounding to the nearest tenth 3.5 divided by 2.29.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

= 3.5/2.29

After dividing we will get:

= 1.528

Rounding to the nearest tenth:

= 1.53

Thus, the answer will be 1.53 after dividing and rounding to the nearest tenth 3.5 divided by 2.29.

The question in English is

Calculate the circumference of the circle entered in a square 8 cm long

we know that

The circumference of a circle is equal to

[tex]C=\pi D[/tex]

where

D is the diameter of the circle

In this problem we have that

the diameter of the circle is equal to the length of the square

so

[tex]D=8\ cm[/tex]

Find the circumference

[tex]C=8\pi\ cm=25.13\ cm [/tex]

therefore

the answer is

The circumference of a circle is equal to [tex]8\pi\ cm\ or\ 25.13\ cm[/tex]

To find the new coordinates of point B after a dilation with a scale factor of 0.25, we multiply its original coordinates by the scale factor. The coordinates of B after dilation are (-0.5, 1).

Finding Coordinates after Dilation

To find the new coordinates of point B after a dilation with a scale factor of 0.25 and a center at the origin, we need to apply the dilation transformation to the original coordinates of B(-2, 4).

Dilation is performed by multiplying both the x and y coordinates by the scale factor. The formula for dilation centered at the origin (0,0) is:

Given the scale factor (k) is 0.25:

Which simplifies to:

Therefore, the coordinates of B in the dilated image are B'(-0.5, 1).

Final answer:

To find the area of a soccer field with a length of 100 yards and a width of 60 yards, the equation used is Area = 100 yards × 60 yards, resulting in an area of 6000 square yards.

Explanation:

To calculate the area of a soccer field with a length of 100 yards and a width of 60 yards, we can use the formula for the area of a rectangle, which is Area = length × width. In this case, we would calculate the area as follows:

Step 1: Identify the Formula

Area = length × width

Step 2: Plug in the Measurements

Area = 100 yards × 60 yards

Step 3: Calculate the Area

Area = 6000 square yards

Therefore, the equation to find the area of the soccer field is Area = 100 yards × 60 yards, giving us an area of 6000 square yards.

Answer:

Distance CD = 6

Step-by-step explanation:

In a rectangle ABCD coordinates of A(-4, 3), B(2, 3) and C(2, -1) are given.

We have to find the distance between points C and D when D is the fourth vertex of the rectangle.

Since in a rectangle length of opposite sides are equal, so AB = CD

distance between A(-4, 3) and B(2,3) = distance between points C and D

√(2+4)²+ (3-3)² = CD

CD = √6² = 6

Therefore CD = 6 is the answer.

Distributive Property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

In numerical form we have:

[tex] a(b+c) =a*b +a*c [/tex]

Now let us use this property for our question:

(-2.5)(3-8y)

Here we have ,

a=(-2.5) , b=3 and c=-8y

So using distributive property here,

[tex] (-2.5)(3-8y) =(-2.5)*(3) +(-2.5)*(-8y) [/tex]

=-7.5 +20y

So answer is -7.5 +20y

By defining the variable 'L' for the number of baseball cards Leo has, we solve for 'L' and determine that Ginny has 210 baseball cards using the equations derived from the given information.

The student has asked a question that involves algebraic expressions and solving equations which is a typical middle school mathematics problem. First, let's define a variable for the number of baseball cards Leo has. Let's call this number 'L'. According to the problem, Alex has 4 less than twice the number of baseball cards as Leo, which can be expressed as 2L - 4. We know that Alex has 128 baseball cards, so we can set up the equation 2L - 4 = 128.

Now, let's solve for L:

Now we know Leo has 66 baseball cards. We can use this information to find out how many baseball cards Ginny has. The problem states that Ginny has 12 more than three times the number of baseball cards that Leo has. This can be expressed as 3L + 12. Since L is 66, we substitute and calculate Ginny's baseball cards:

Ginny's baseball cards: 3(66) + 12 = 198 + 12 = 210

Answer:

6

Step-by-step explanation:

Common difference of an arithmetic progression is the difference between the preceding term and the succeeding term of the sequence.

Given the arithmetic sequence 4,10,16,22...

To calculate the common difference, first, we say let the first term be T1, second term be T2, third term be T3 and the fourth term be T4.

Taking the difference of the terms to know the common difference can be gotten as thus;

T2-T1 = T3-T2 = T4-T3 = k

The value of k must be the same for all the difference. This will give;

10-4 = 16-10 = 22-16 = 6

Since their difference gave the same value, therefore the common difference of the sequence is 6

In this problem, you are asked to write a number in scientific notation. In figures, 78 million would look like this:

78,000,000

To write this to scientific notation, you have to move the decimal point to the left until you will get a number between 1 and 10.

Here, you will have to move the decimal point 7 times to get 7.8

The exponent of the scientific notation is the number of times you moved your decimal point. Since the movement of decimal point is going to the left, you will have a positive exponent.

The scientific notation would look like this:

7.8 x 10^7
