Find the value of x.

Answers

Answer:

x = 30°

Step-by-step explanation:

< A = 90° {Being vertically opposite angles }

Now

x + 90° + 2x = 180° (Being linear pair)

3x = 180° - 90°

3x = 90°

x = 90° / 3

x = 30°

$725
$1,050
$1,375
75
H. p = 13c + 75
100
J. c = 13p + 75

Answers

Answer:

The answer is j

Step-by-step explanation:

The equations shows the relationship between c and p is p= 13c + 75.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have table which shows amount that a catering company charges based on the number of people at an event.

So, the equation that can framed from the table as

(y- 400)= (725- 400) / (50-25) . (x-25)

y- 400 = (325/ 25) (x-25)

y-400 = 13(x-25)

y-400 = 13x - 325

y = 13x - 325 + 400

y= 13x + 75

or p = 13c+ 75

In a polling station, there were 900 registered voters. During an election 10% of the registered voters did not cast their votes. The rest cast their votes to Ahmed, Babu and Chambuko in the ratio 3:2:1.If 30 votes were spoilt,how many votes did Ahmed get?

Answers

Answer:

Ahmed got 390 votes

Step-by-step explanation:

Here, we want to know the number of votes obtained by Ahmed

from the question, there were 900 registered voters

10% did not cast their votes

The number that didn’t cast their votes will be;

10% of 900

= 10/100 * 900 = 90

So the rest 90% casted and this value will be 900-90 = 810

810 people casted their votes

30 votes were spoilt;

The number of valid votes is thus;

810 - 30 = 780

Ahmed got a ratio of 3 in 3:2:1

The total value here is 3 + 2 + 1 = 6

So what Ahmed got will be;

3/6 * 780

= 780/2 = 390

Jackson bought a jar of 240 marbles. The percent bar graph shows the percentage of each color marble in the jar.

How many of the marbles are yellow?

Answer: 14/33

Step-by-step explanation:

Since 2/9 of the umbrella are blue, the fraction for red umbrellas will be:

= 1 - 2/9

= 7/9

Since 5/11 of the red umbrellas have plastic covers. The fraction for those without plastic covers will be:

= 1 - 5/11

= 6/11

Therefore, the fraction of Michelle's red umbrellas that do not have plastic covers will be:

= 6/11 × 7/9

= 42/99

= 14/33
