Keri's total score in her last gymnastics which had three different types of acts is 17.25.

A decimal separates the whole part and the integer part of a given number. Decimal can also be written as fractions.

Keri in her last gymnastics competition scored a 5.65 on the floor exercise, 5.85 on the vault, and 5.57 on balance.

∴ Her total score will be the sum of all the scores she obtained in all those three performances which are,

= ( 5.65 + 5.85 + 5.75).

= 17.25.

The center of the circle is (3, -1) and the radius  of the circle is 4

The equation of the circle is given as

x^2 + y^2 - 6x + 2y = 6

The above equation is the standard equation of a circle

Start by converting the above standard equation of a circle to a form other than the standard equation

Using a graphing calculator, we have the following form

(x - 3)^2 + (y + 1)^2 = 4^2

The equation of a circle is represented as

(x - h)^2 + (y - k)^2 = r^2

Where the center is

Center = (h, k)

So, we have

(h, k) = (3, -1)

This means that

Center = (3, -1)

Hence, the center of the circle is (3, -1)

Answer:

Step-by-step explanation:

Given square TUVW, you want the perimeter and area of square T'U'V'W' after it has been dilated by a factor of 5/2 and translated by (0, -8).

Counting grid squares, or reading coordinates, we find the length of a side of square TUVW to be 8 units. Then the perimeter is ...

  P = 4s = 4·8 = 32 . . . . units

After dilation, the perimeter of the square is the preimage value multiplied by the dilation factor.

 perimeter of T'U'V'W' = (5/2)(perimeter of TUVW) = (5/2)(32 units)

  perimeter of T'U'V'W' = 80 units.

The area is the square of the side length. The side length of T'U'V'W' is ...

  s' = (5/2)(8) = 20 . . . . units

Then the area is

  A' = (s')² = (20 units)² = 400 units²

area of T'U'V'W' is 400 units².

__

Additional comment

Translation is a rigid transformation. It does not change the dimensions, so does not change the perimeter or area of the dilated square.

The smallest interior angle of a triangle, produces largest exterior angle. Hence, measurement of the exterior largest angle is 359.47°

An angle is the figure formed by the two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by the two rays lie in the plane that contains the rays. Angles are also formed by the intersection of the two planes. These are called the dihedral angles. Two intersecting curves may also define an angle, which is the angle of rays lying tangent to the respective curves at their point of intersection.

Angle is also used to designate the measure of an angle or of rotation. This measure is the ratio of length of a circular arc to its radius. In the case of a geometric angle, arc is centered at the vertex and delimited by the sides. In case of a rotation, the arc is centered at the center of the rotation and delimited by any other point and its image by the rotation.

We know that sum of all the angles of a triangle is equal to 180°

s°+(1/7s+3)°+(1/7s+30)°= 180°

[tex]s+\frac{22}{7}s+\frac{22}{7}s[/tex]= 180°

[tex]\frac{51}{7} s[/tex]=180°

s= 24.7°

both the similar angles =0.53°

Therefore, the largest external angle is:

360°-0.53° = 359.47°

The equation 4y = -4x + 2³​ is a linear function

A linear function can be explained as an algebraic equation, whose every  term is either a constant or the product of a constant and a variable (raised to the first power only).

The equation 4y = -4x + 2³​ is a linear function since both variables x and y meet the criteria, and both constants a and b do comply with rules as well

The exponent of x is 1, that is, it is raised to the first power only and the equation follows the definition of a function: for each input (x) there is only one output (y). The graph of any linear function in one variable  is always  a straight line.

The girls ran 8 laps in one hour, for the boys it is 48:6

Step-by-step explanation:

The girls ran 4 laps in 30 minutes so per hour is was be 8 laps because 4x2. So on the paper it would be 4x2=8

For the boys it would be 8x6 which is 48 dollars in one hour and 6 laps per hour so it would be 48:6 so just put 8x6=48 and it should work.

Width of the box is 8 inches and length is 11 inches.

Height of the box is 9 inches given

Length of the box is 3 inches more than the width.

Let the width be x then length = x+3

Volume of the box is = 792 (given)

Volume is the amount of space occupied by the any three dimensional figure. To find the volume of a box we simply multiply length width and height

Volume = length * width * height

792 = (x+3)*x*9

[tex](x^2+3x)*9=792\\9x^2+27x=792\\9x^2+27x-792=0[/tex]

Divide the above equation by 9 as 9 is the common factor

we get

[tex]x^2+3x-88=0[/tex]

now solve this equation by splitting the middle term we get,

[tex]x^2+11x-8x-88=0\\x(x+11)-8(x+11)=0\\(x+11)(x-8)=0\\x=-11,8[/tex]

width is always positive so we consider x = 8

Length = x+3 = 8+3 =11

Answer:

5:2

Step-by-step explanation:

A ratio is basically a fraction but horizontally for eg. this: 5:8! This question is asking us to find the ratio of the emails that Jamie received to the emails that she answered.

According to the question, Jamie got 20 emails and responds to 8 of them. The ratio would look like this: 20:8 (because a ratio is just a fraction but horizontal, doesn't mean that there will be mixed numbers!) but not this 8:20. Ratios have a specific order that they have to be in and that will vary depending on the question. If the question says to find the ratio of emails that Jamie responded to to the emails that she received, then in this case 8:20 would be correct.

For now, the answer is 20:8. However, we still need to simplify it by finding its lowest common factor (unless the question asks you to not simplify it, it's better to simplify the answer like a fraction). The lowest common factor would be 4 for 20 and 8. 4 goes in 20 5 times sand 4 goes into 8 2 times.

Your final answer should be: 5:2

The required measure of the line DE segment is 29.

What does a line in mathematics mean?

(9) Given ,

               DF = 42

Here,

DF = DE + EF

From the given put the values of  DF = 42, DE = 7x +1 and EF = 4x - 3

42 = 7x + 1 + 4x - 3

42 = 11x - 2

11x = 44

x = 4

DE = 7x + 1

Put the value of x in above equation,

DE = 7 * 4  + 1

DE = 28 + 1

DE = 29

Thus, the required measure of the DE segment is 29.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Madison and Cindy have a combined age of 65 Cindy is 20 less than four times Madison's age. The age will be calculated by using the information.

C + M = 65

C = 4M - 20

4M - 20 + M = 65

5M = 65 + 20

Hence:
