The two ways of forming isosceles triangle by bending the metal strip using length by length by base are

A triangle that have the two sides equal is referred to as an isosceles triangle.

Using a strip of 20 inches long to construct an isosceles triangle means that the perimeter of the triangle is 20 inches

the perimeter is equal to base + length + length

bending 6 inches already means one of the dimensions is gotten then fo the other is based on if

if the 6 is base then minus the 6 from 20 and divide the rest for the length

20 - 6 = 14

the two lengths is 14 one length is 7. so we have 6 + 7 + 7 = 20

If the 6 is length then get another 6 and the rest is base

20 - 6 = 14

14 - 6 = 8

therefore we have 6 + 6 +8 = 20 inches

The meaning of the c-value when T=65 is:  The number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

The correct answer is an option (D)

In this question, we have been given a linear relationship.

For a certain type of cricket, this relationship can be expressed using the formula T=34+0.3c,

where T represents the temperature in degrees Fahrenheit and

c represents the number of times the cricket chirps in one minute.

We need to interpret the value of c when T = 65.

T = 34 + 0.3c

65 = 34 + 0.3c

c = 103.33

c = 103.33 represents the number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

Therefore, the meaning of the c-value when T=65 is:  The number of times the cricket could be expected to chirp in one minute if it's 65 degrees F

S= 0.0625t² is the composition of a function to represent the area of the puddle as a function of time.

The defined region represents the extent of the area on a plane or curved surface. The area of ​​a planar region refers to the area of ​​a shape or planar layer, while surface area refers to the area of ​​an open surface or boundary of a three-dimensional object. Area can be defined as the amount of material of a certain thickness required to model the mold, or the amount of paint required to cover the surface in a single layer. This is a two-dimensional equivalent of the length of a curve or the volume of a solid..

We obtain the data from the equation.

The radius is increased by 0.25 Cm for each t min.

Assume that the puddle's area is S.

We all know that.

Circle area =  πr²

So, S= πr²

S= π(0.25t)²

Answer:

12.5 72

Step-by-step explanation:

Because shows that the basketball player wear size 11.5 73 inches tall so basically the answer would be 12.5 72

The equation of the regression line is y = 0.77x + 61.95. The residual is 2.2 inches. The residual means that the gap between the estimated and anticipated values is 2.2 inches.

A regression line shows a linear connection between the y-dependent axis's variables and the x-independent axis's variables. The connection is determined by examining the data pattern created by the variables.

From the table, the points are given as follows:

(7, 64.5), (10, 70), (12.5, 72), (8.5, 71), (9, 69), (10, 70), (11, 75), (12.5, 69), (13, 71), (10.5, 68).

Inserting these points into the linear regression calculator, the equation is given as follows:

y = 0.77x + 61.95 ...(i)

For a shoe size of 11.5 inches, the predicted height is given as below:

y = 0.77(11.5) + 61.95 = 70.8 inches.

The residual is the gap between the estimated and anticipated values, hence:

Residual = 73 inches - 70.8 inches = 2.2 inches.

Answer:

The 5 consecutive odd integers are 11 , 13 , 15 , 17 , 19

Step-by-step explanation:

The Difference between any odd Integer and its consecutive Integer = 2

So let the 3rd Odd Integer be x

Then the 1st Odd Integer is x - 2

and the 2nd Odd Integer is x - 4

and the 4th Odd Integer is x + 2

and the 5th Odd Integer is x + 4

Since the Sum of the 1st three integers is 3 more than the sum of the last two

Then 1st + 2nd + 3rd = 4th +5th +3

Then (x) + (x - 2) + (x - 4) = (x + 2) + ( x + 4) +3

Then 3x - 6 = 2x + 9

subtract 2x from both sides

3x - 2x -6 = 9

x - 6 = 9

Add 6 for both sides

Then x = 9 + 6 = 15

So the 3rd odd Integer is 15

So the five consecutive odd integers are 11 , 13 , 15 , 17 , 19

Step-by-step explanation:

the expression is

45 × 12 + 45 × 32

this is the same as

45 × (12 + 32)

you can extract a common factor from a sum and make it the central factor for the sum.

it is the opposite operation of simplifying this central multiplication, where you have to multiply every part of the left factor with every part of the right factor and sin things up according to the resulting signs.

so, the 4th answer is correct.

The inequality that compares the given numbers -4;-1 is -4 < -1.

Inequalities are created through the connection of two expressions.

It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.

In this case, it should be noted -4 is less than -1. Therefore, the inequality will be -4 < -1.

It may include one or more groupings, as well as some, all, or neither of the items found inside those groups. It is helpful to initially identify various groups and components that you believe to be connected in some way before establishing Rules of Visibility.

Because of the differences in the relative percentages of the column-wise frequencies, there is a link between the variables. The animal mascot in the first column has 74% victories and 26% defeats.

Here in the rhombus ABCD the value of y is 7.5.

A rhombus is a unique kind of quadrilateral with four equal sides and perpendicular diagonals that cut the angles and one another in half.

So here 4x+15 = 7x+2 and

12y = 90.

To find the remaining values by first solving for each variable, then substituting as necessary.

4x+15=7x+2

15=3x+2

13=3x

13/3 = x

BC is 4x+15

= 4(13/3)+15

= 52/3 + 45/3

= 97/3

CD is 7x+2

= 7(13/3)+2

= 91/3 + 6/3 = 97/3

Then, find 12y=90 and y=7.5.

AFB is a 90° angle (12(7.5)).

BCF is a 4y-1 = 4(7.5)-1 = 29 angle.

Because the diagonal cuts the angle in half, angle BCD is equal to 58. Angle ABC thus becomes 180-58 = 122.

Therefore the value  of  y  is 7.5 .
