Answer:

31.5x; 56.25%

Step-by-step explanation:

For the first question:

We can write 35% as 0.35; this is because 35% = 35/100 = 0.35. Taking a percentage of a quantity means we multiply; this gives us

0.35(90x) = 31.5x

For the second question:

To find the percentage the second quantity is of the first one, we divide:

9x/16x = 0.5625

This is the same as 56.25%.

Which equation is represented by the intersection of the graphs below? Image is above.

zaharov [31]

Option B:

sin x = 1 is the equation represented by the intersection of the graph.

Solution:

The graph lies between -1 and 1 in y-axis.

x-axis of the graph is all real numbers.

The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.

That is the domain of the graph is all real numbers.

The range of the graph is [-1, 1].

It clearly shows that, it is the graph of sinx = 1.

Hence sin x = 1 is the equation represented by the intersection of the graph.

Option B is the correct answer.

The ratio of the number of cups of yellow paint to the number of cups of blue paint that Greg mixed to make a shade of green pai

ziro4ka [17]

Answer:

Part A: A ratio of 2:1 means that he uses 2 cups of yellow paint for each cup of blue paint.

-------------------------------------------------------------------------------------------------

Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:

2/1 = 1/x

x = (1*1) / 2

x = 1/2

For each cup of yellow paint, Greg should add 1/2 cup of blue paint.

-------------------------------------------------------------------------------------------------

Part C: 6 cups cost $54, then 1 cup cost:

54 / 6 = 9

The price per cup of yellow paint is $9.

Find x (7x-11) (2x-3) (5x-2)

Tomtit [17]

Answer:

x = 14

Step-by-step explanation:

Total angle measure of a triangle - 180°

Add all the angles together and make them equal to 180.

Solve for x.

7x - 11 + 5x - 2 + 2x - 3 = 180

14x - 16 = 180

14x - 16 + 16 = 180 + 16

14x = 196

$\frac{14x}{14} = \frac{196}{14}$

x = 14
