Answer 1

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14

Answer:

14. She deposited $15.50 into her bank.

15. The width would be 900.

Step-by-step explanation:

14. 245.60 + x = 261.10

x = 15.50

245.60 + 15.50 = 261.10.

She deposited $15.50 into her bank and resulted in her new bank balance appearing as $261.10.

15. Width is 900 cm

Length is 12 cm.

A = L X W = 108

A = L * 3/4L

108 = 3/4L2

Divide both sides by 3/4: multiply both sides by the inverse of 3/4 or 4/3.  

(4/3)*108 = L2

144 = L2

√144 = L

12 = L

W = 3/4*12

W = 9

Before we finish:

 

A = 108 = 9 x 12 = 108

W/L = 3/4 = 9/12 = 3/4

The width of the rectangle would be 3/4.

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio ​

Answers

Answer:

6:2

Step-by-step explanation:

X share from old ratio is 1/2

Y share from old ratio is 1/3

Z share from old ratio is 1/6

Now, we are told Y retires and that X and Z purchase his shares.

Thus;

Amount X took from Y = 1/2 × 1/3 = 1/6

Amount Z took from Y = 1/6 × 1/3 = 1/18

Thus, new share of X is now; 1/6 + 1/2 = 2/3

New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9

Ratio is now X:Z = 2/3 : 2/9 = 6:2

slope and y-intercept of the graph of 25x -20y =100

Answers

Step-by-step explanation:

First, we need to put this standard form into slope-intercept form

To do this you need to move the "y" to all by itself

-25x+25x-20y=100-25x

-20y=100-25x

y=5/4x-5

Answer:

y=5/4x-5

The slope is-5/4 and the -intercept is (0,5)

How to find the slop?

Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.

25x−20y=100

20y = 100 + 25x

20y=100+25x

y = [tex]5 + \frac{5}{4}[/tex]

She concluded that the slope is   [tex]\frac{5}{4}[/tex]

​and the y-intercept is (0,5).

y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.

The slope is-5/4 and the -intercept is (0,5)

Finding the value of y at x=0 will allow you to locate the y-intercept on a graph. The graph's intersection with the y-axis occurs here.

m=3 and through (2, -1) in slope-intercept

Answers

Answer:

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3, then

y = 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = 3x - 7 ← equation of line

Work out the size of obtuse angle DOF, giving a reason for your answer.

Answers

Answer:

104

This is because angle at the center is twice the angle at the circumference

Step-by-step explanation:

104 is the size of obtuse angle DOF because the angle at the center is twice the angle at the circumference.

What is an obtuse angle?

An obtuse angle is any angle greater than 90 °: Straight angle is a measurement angle equal to 180 °: Zero angles is a measurement angle equal to 0 °: Complementary angle is the angle at which the sum of the measurements is 90 °: Complementary angles are the following angles: The total dimensions are 180 °.

Now we know that angles below 180 degrees and above 90 degrees are obtuse. Examples of bluntness include 110 °, 135 °, 150 °, 179 °, 91 °. Therefore, all angles in the range of 90 ° to 180 ° are obtuse.
