Answer:

Cans for food drive

Step-by-step explanation:

Answer:

Cans for food drive

Step-by-step explanation:

The header should encapsulate all aspects of the table.

Cans of food are brought by the teachers to be donated to the food drive. Hence the answer should be cans for food drive.

Cans recycled are out of context as the cans of food are for donation as seen in the table, not for recycling.

Favourite food and favourite teacher cannot be measured by the data provided which is which teacher bringing how many cans of food for donation. Hence, these 2 are not the answer as well.

Answer:

20%

Step-by-step explanation:

Let x represent the initial value of the stock at the beginning of 2006. And y the value at the end of 2006.

When it went up by 25% in 2006;

y = x + 25% of x = x + 0.25x = 1.25x

For the value to go back to the original price, it has to decrease from y to x;

y = 1.25x

The percentage decrease from y to x is;

= (y-x)/y × 100%

Substituting the values;

= (1.25x -x)/1.25x × 100%

= 0.25x/1.25x × 100%

= 0.2 × 100%

= 20%

Therefore, it will have to go down 20%

Answer:

Denote the two numbers: a and b

Two numbers are in the ratio 7:5

=> a/b = 7/5

=> a = (7/5) x b     (1)

When 10 is subtracted from each term , the ratio becomes 3:2

=> (a - 10)/(b - 10) = 3/2

=> 2 x (a - 10) = 3 x ( b - 10)

=> 3 x b - 2 x a = 10

From (1) => 3 x b - 2 x (7/5) x b = 10

             => (1/5) x b = 10

             => b = 50

             => a = (7/5) x b = (7/5) x 50 = 70

Hope this helps!

Step-by-step explanation:

Given the two linear equation

–4x – 7 = y ...1

x² – 2x – 6 = y ...2

Equating the left hand side of both equations since they are equal to the same variable  y will give;

[tex]-4x-7=x^{2} -2x-6\\collecting\ the\ like\ terms\\x^{2} -2x+4x-6+7 = 0\\x^{2} +2x+1 = 0\\x^{2} +x+x+1 = 0\\x(x+1)+1(x+1)=0\\(x+1)^{2}=0\\ taking\ square\ root\ of\ both\ sides\\x+1 = 0\\x = -1\\[/tex]  

Substituting x=1 into equation 1 we have;

[tex]y=-4(-1)-7\\y=4-7\\y = -3[/tex]

This means there is only one unique real number solution at (-1, -3)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the length of a rectangle = 3x+10

Width of the rectangle = x+12

Perimeter of the rectangle = 76ft

For us to get the area of the rectangle we need to get the value of its length and width.

Given the perimeter of a rectangle P = 2(L+W) where;

L is the length and W is the width, on substitution

76 = 2(3x+10+x+12)

76 = 2(4x+22)

76 = 8x+44

8x = 76-44

8x = 32

x = 32/8

x = 4

Substituting x = 4 into the function of the length and width we have;

Length = 3(4)+10

Length = 22feet

Width = 4+12

width = 16feet

Area of the rectangle = Length * Width

Area of the rectangle = 22feet * 16feet

Area of the rectangle = 352ft²

Answer:

the real answer is (8,-4)

Step-by-step explanation:

If the midpoint of the AB is (5.5, 0) then the coordinate of the B will be given as (8, -4).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A is at (3, 4) and point M is at (5.5,0).

Point M is the midpoint of points A and B.

Then the point of B is given as

[tex]\rm (x_1,y_1) = (2x-x_2, 2y-y_2)\\\\(x_1,y_1) = (2\times 5.5 - 3, 2\times 0-4)\\\\(x_1,y_1) = (8, -4)[/tex]

An equivalent expression in scientific notation is,

⇒ 6.45 × 10³

Option C is true.

Scientific notation is a way of writing a very large or very small numbers. For example; 230,000,000 can be written in scientific notation as 2.3 x 10⁸.

Given that;

The expression is,

⇒ (4.5×10²) + (6.0×10³)

Now, We can simplify the expression as;

⇒ (4.5×10²) + (6.0×10³)

⇒ (4.5×10²) + (60×10²)

⇒ (4.5 + 60) × 10²

⇒ 64.5 × 10²

Answer:

You need to add 12 pint of yellow.

Step-by-step explanation:

This is the method I used:

There is 4 pint of Yellow (Y) and 4 pint of Blue (B)

because they said is in equal amounts, so they are 50% each.

We need 80% Y and 20% B

so 4:20 = x=80   (4 pints is 20% as "how many pints" is 80%)

So x = 16

We already have 4 pint of Yellow, so we need more 12.

6.4 pint of yellow paint we need to add to the mixture.

"A percentage is a number or ratio that can be expressed as a fraction of 100."

"It is a statement which consists of equal symbol between two mathematical expressions."

For given example,

8 pint mixture of paint that is made up of equal amounts of yellow paint and blue paint.

Let we need 'x' amount of yellow paint.

To create a certain shade of green, you need a paint mixture that is 80% yellow.

So, we get an equation [tex]\frac{x}{8}\times 100 =80[/tex]

We solve above equation.

[tex]\Rightarrow \frac{x}{8}\times 100 =80\\\\\Rightarrow \frac{x}{8} = \frac{80}{100}\\\\ \Rightarrow x = 0.8\times 8\\\\\Rightarrow x = 6.4~~pints[/tex]

Therefore, 6.4 pint of yellow paint we need to add to the mixture.

9( ×12 +a{6}) is 108

Answer:

( - 6 , 26 )

Step-by-step explanation:

You can solve this in a number of ways, you can graph it, you can substitute the value of x into the first equation, or you can do it the elimination method.

So lets just do the substitution method because i can't do the others on here, i can't write :/.

so substitute x = -6 into the equation y = -3x + 8

y = -3(-6) + 8

y = 18 + 8

y = 26

Answer: 0.0625

Step-by-step explanation:

From the question, Steven rolled a 1-6 number cube four times. This means the 1-6 number cube has numbers 1, 2, 3, 4, 5 and 6. There are 3 odd numbers which are 1, 3 and 5. If the 1-6 number cube is rolled once, the probability will be:

3/6 = 1/2

Since Steven rolled the 1-6 number cube four times, the probability of getting an odd number on all four rolls of the die will be:

= 1/2 × 1/2 × 1/2 × 1/2

= 1/16

= 0.0625

Answer:

In a right triangle, as the angle increases, the value of the sine increases.

Step-by-step explanation:

Think of the unit circle, a circle with radius 1 unit centered at the origin which is the point with coordinates (0, 0). Draw a radius of the circle from the center, to point (1, 0) on the positive x-axis. The angle formed by this radius and the positive x-axis is 0 degrees. This is an angle in standard position. The endpoint of the radius on the circle has a y-coordinate. The y-coordinate is the sine of the angle. As you choose points on the circle going up from the positive x-axis, the angle formed by the radius connected to the point on the circle and the positive x-axis increases in measure until it coincides with the positive y-axis, where it has a measure of 90 degrees. The sine of the angle is always the y-coordinate of the point on the circle. As the angle increases from 0 to 90 degrees, the y-coordinate increases from 0 to 1. The acute angles of a right triangle can have measures of only between 0 and 90 degrees.

Answer: In a right triangle, as the angle increases, the value of the sine increases.

Answer: 18.75%

Step-by-step explanation:

Here is the complete question:

Last month, a cafe had 3200 customers. 600 of them ordered gluten-free meals. What percentage of the customers ordered gluten-free meals?

To find the percentage of the customers who ordered gluten-free meals, we will divide the number of people who ordered glutton free meal by the total number of customers and then multiply by 100. This will be:

= 600/3200 × 100

= 0.1875 × 100

= 18.75%

Step-by-step explanation:

To find how many students don't prefer soccer, we have to take 90% of 50. This is because 10% of the 50 students like soccer, so the percentage that don't like it is 100-10=90%. 90% of 50 = 0.9*50 = 45 students.
