50. If angles are complementary, what’s value of x?

Answer:

B

Step-by-step explanation: i took the test on docs/forms

Okay, we see that there are 10 pieces in the circle - thus, it is our denominator. Next, we see that 9 out of them are coloured in. Therefore, the fraction is 9/10. To express our answer as a percent, we need to divide 9 and 10 to get 0.9. Then, we multiply 0.9 by 100 to get 90%. As a result, your answer is 90%.

The percentage of the shape that is purple is approximately 90%.

To find the percentage of the shape that is purple, we need to calculate the proportion of purple pieces out of the total number of pieces and express it as a percentage.

Given that there are 10 pieces in total and 9 of them are colored in, we can calculate the percentage as follows:

Percentage of purple pieces = (Number of purple pieces / Total number of pieces) × 100

Percentage of purple pieces = (9 / 10) × 100

Percentage of purple pieces = 0.9 × 100

Percentage of purple pieces = 90%

Therefore, the percentage of the shape that is purple is approximately 90%.

22-18=4  18-18=/

18x1=18

22=18(1)+4

22-18(1)=4

Answer:

22=18x + 4

Step-by-step explanation:

collect like terms 22 and +4

+4 crosses equality sign and turns to -4

you get 22-4=18x

therefore 18x=18

cancel 18 in both sides x = 1

Step-by-step explanation:

Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.

We have 180° - 360°/n = 160°.

=> 360°/n = 20°, n = 18.

Therefore it is a 18-sided regular polygon.

Answer:

4 : 1

Step-by-step explanation:

(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.

1 day = 24 hours, 3 days = (3 × 24) hours

3 days = 72 hours

Now both the units are same, so we can easily simplify now.

72 hours : 18 hours

36 : 9 = 12 : 3

= 4 : 1 ( Answer)

Answer:

9.67 feet

Step-by-step explanation:

The length of the chord is approximately 8.16 feet. The correct option is 4.

A line segment connecting two points on a circle is referred to as a circle's chord in geometry. The circle's center is traversed by the longest segment that can be drawn between any two points on the circle.

To get the chord's length, we can utilize the formula for a circle's chord length. The equation is:

Length of chord = 2r sin(θ/2)

where r is the circle's radius, is its radian central angle, and sin is the sine function.

First, we need to convert the central angle from degrees to radians:

θ = 65° = (65/180)π = 1.14 radians

Now we can plug in the values:

Length of chord = 2(9 feet) sin(1.14/2) ≈ 8.16 feet

Therefore, the length of the chord is approximately 8.16 feet.

Answer:

£152

Step-by-step explanation:

Solution:

Find out how much is 1/3 of 255 coins:

255 x 1/3 = 85

Since you know how many 50p and £1 coins there are, the remaining of the coins after the 50p and £1 get deducted from the total coins.

255 - 85 - 110 = 60

There are 60 20p coins, 85 £1 coins and 110 50p coins.

Find out the total value by calculating them all altogether.

60 x 20p = 1200

85 x 100p which is £1 = 8500

110 x 50p = 5500

I did them separately so that it wouldn't be so confusing.

Convert them into £, then after that add them up.

£12 + £85 + £55 = £152

Answer:

4years

Step-by-step explanation:

Let the present age of Mark be x

Let the present age of Max be y

Five years ago

Mark = x-5

Max = y - 5

If mark was twice as old as Max, then;

x - 5 = 2(y-5)

x-5 = 2y - 10

x-2y = -10+5

x - 2y = -5 ... 1

In three years,

mark = x+3

Max = y+3

Now if Max's age will be 2/3 that of Mark, then;

x+3 = 2/3(y+3)

3(x+3) = 2(y+3)

3x + 9 = 2y+6

3x-2y = -3 .... 2

Solve 1 and 2 simultaneously

x - 2y = -5 ... 1

3x-2y = -3 .... 2

From 1: x = -5 + 2y

Substitute into 2:

3(-5+2y) - 2y = -3

-15 + 6y - 2y = -3

-15 + 4y = -3

4y = -3 + 15

4y = 12

y = 3

Recall thet x = -5+2y

x = -5+2(3)

x = -5 + 6

x = 1

The sum of their ages will be x+y

x+y = 1+3

x+y = 4

Hence the sum of their ages now is 4years

Answer:

0.67 feet

Step-by-step explanation:

This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%

So, we have:

[tex]T_n = ar^{n-1}[/tex]

In this case:

[tex]r - 80\% = 0.8[/tex]

[tex]n = 11[/tex]

So, we have:

[tex]T_{11} = 6.25 * 0.8^{11-1}[/tex]

[tex]T_{11} = 6.25 * 0.8^{10}[/tex]

[tex]T_{11} = 6.25 * 0.1073741824[/tex]

[tex]T_{11} = 0.67ft[/tex]

Hence, the height of rebound at the 11th time is approximately 0.67

Answer:

Step-by-step explanation:

1/3 times9=3

Step-by-step explanation:

Equations:

68.75 = 0.5c + 1.25m

c + m = 100

First, let's get rid of one of the variables. Let's start with the simplest equation first. Let's move a variable, so that only one variable is equal to the rest of the equation.

c + m = 100 to c = -m + 100

(it doesn't matter which variable)

Next, since we have what variable c is equal to, we will now incorporate it into our more complex equation.

68.75 = 0.5(-m + 100) + 1.25 m

Now, to get rid of the parentheses, and just have a regular addition equation with the only variable being m.

68.75 = -0.5m + 50 + 1.25m

Next, we need to make it so that there is only one version of the variables. Just combine the variables together so that the form one cohesive unit.

68.75 = 0.75m + 50

Now, we are going to do the same thing that we did in our first equation (with a mix of the last step we just did), but instead of variables, we are going to do it with the whole numbers instead, and converge them onto one side of the equal sign. Keep in mind that at this step in the process, the variable with it's cohesive unit should be isolated on one side of the equal sign and the other being taken up solely by whole numbers.

118.75 = 0.75m

Now, we just need to make the variable equal to 1 (or just m). So we must either multiply or divide. In this case we will be multiplying both sides by 0.75.

118.75 x 0.75 = 0.75m

So, after this step, you should have an answer of;

89.0625

However, you can't just sell a 0.0625% portion of something to somebody (especially muffins, like come on). Also, the amount of cookies and muffins must be equal to 100 and each variable is in whole numbers (usually).

*Always make sure that when you are done with a problem that you double check it. Usually, with equations like this, you just plug in the variables into the equations, and if they fit both equations, you've done well.

From this point forward, I'm leaving you to your own devices. It's 2:38 a.m. and I need to get up at 7:15. I hope this helps!
