Answer:

[tex]\sqrt{2}[/tex] and 4[tex]\sqrt{11}[/tex]

Step-by-step explanation:

To simplify like surds, add/ subtract the coefficients.

(a)

[tex]\sqrt{2}[/tex] (6 - 5)

= [tex]\sqrt{2}[/tex] (1)

= [tex]\sqrt{2}[/tex]

(b)

[tex]\sqrt{11}[/tex] ( 1 + 3)

= [tex]\sqrt{11}[/tex] (4)

= 4[tex]\sqrt{11}[/tex]

Answer:

170

Step-by-step explanation:

Let x be the original price

x* .20 is the decrease

x - .20x = new price

.80x = new price

.8x = 136

Divide each side by .8

.8x/.8 = 136/.8

x =170

Step-by-step explanation:

the rate of change is constant in y (adding 3) and x (adding 2)

Answer:

y = - x + 4

Step-by-step explanation:

The first step is to find the slope-intercept form, which is:

y=x-6.

Then, y=x+6

y=-x+4 should be the answer since it passes through the point (-1, 5)

Answer:

y=x+6

Answer: 16 yards would be your answer

The  scale factor of ABCD to QRST is 1:2

The perimeter of rectangles ABCD and QRST are 56 yards and 112 yards respectively.

Rectangle ABCD has a width of 8 yards and a length of 20 yards.

Rectangle QRST is similar to rectangle ABCD.

Rectangle QRST has a length of 40 yards.

Therefore, the scale factor of ABCD to QRST can be calculated as follows:

let

x = width of rectangle QRST

8 / x = 20 / 40

8 / x = 1 / 2

x = 16

The scale factor of  ABCD to QRST is 1:2

perimeter ABCD = 2(8 + 20) = 56 yards

perimeter QRST = 2(16 + 40) = 112 yards.

Answer:

x = 70/9

Step-by-step explanation:

9x - 81 = -11

move it to the right

9x = -11 +81

calculate

9x = 70

divide both sides

x = 70/9

Answer:

16

Answer:

3 carrots, 4 crackers, and 6 grapes.

Step-by-step explanation:

The greatest common factor of 9, 12, and 18 is 3, so we know that we can make at most 3 identical lunchboxes. Now we have to divide each number by 3 to figure out how much of each item is in each lunchbox. 9/3=3, 12/3=4, and 18/3=6 so there will be 3 carrots, 4 crackers, and 6 grapes in each lunchbox.

Step-by-step explanation:

Answer:

-6 is the missing value.....

Answer:

(-6, 8); the missing value is -6

Step-by-step explanation:

First, you need to solve the given equation for x

1: 2x + 3y = 12 (Given)

2: 2x = -3y + 12 (Subtract 3y from both sides to isolate x)

3: x = -1.5y + 6 (Divide both sides by 2)

Now, you can solve for the missing x in the solution set (x, 8):

where x = -1.5y + 6 and y = 8,

x = -1.5(8) + 6

x = -12 + 6

x = -6

So, the missing value is -6

Answer:

Step-by-step explanation:

Answer:

C. 2/3

Step-by-step explanation:

To solve this, we should come up with a common denominator first.

The least common denominator (LCD) of the four fractions would be 120.

So, first multiply each fraction's denominator to get 120, and multiply the numerator by the same amount.

ex. 3/4

4 x 30 = 120

3 x 30 = 90

We get 90/120.

After doing this with each fraction, we get;

13/15 = 104/120

7/8 = 105/120

2/3 = 80/120

3/4 = 90/120

Now, it is easier to see which fraction has the least value (or the one that is the smallest. Your answer is 2/3, since 80/120 is the smallest out of the four.

Answer:

y = x-3 is the equation

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

The general equation form of a straight line is;

y = mx + b

Fro the equation;

y = -1x + 2

The slope is -1

So the equation of the perpendicular line is as follows;

-1 * m = -1

m = 1

so we can use the point-slope equation form

That would be:

y-y1 = m(x-x1)

y-3 = 1(x-6)

y-3 = x-6

y = x-6+3

y = x-3

Answer:

C

Step-by-step explanation:

Since a triangle's area is half as much as a rectangle or square, considering that they have the same width and length, you can basically eliminate choices a and b.

Choice d doesn't make sense because it's a square, now you are left with choice c.

Answer:

I think it might be d.

Answer:

The runner’s time is 3.18 minutes

Step-by-step explanation:

Mathematically;

z-score = (x-mean)/SD

In this question, we have the z-score but we want to calculate x

From the question

z-score = -1.76

mean = 4.5 minutes

SD = 0.75 minutes

x = ?

Substituting these values, we have that

-1.76 = (x-4.5)/0.75

0.75(-1.76) = x - 4.5

-1.32 = x - 4.5

x = 4.5 -1.32

x = 3.18

Answer:

3.18
