Answer:

200 in^2

Step-by-step explanation:

If it only asking the area in yellow, then it is consisted of two squares, for each square, it is 10in * 10 in for area, so for two squares, the area will be 2*10*10 = 200 in^2.

1.Let x = 6.

spayn [35]

Answer:

1: 6

2: 1,2,3

3: 4m-1>5m-4

4: Not enough data

5: n = 11

6: The ceiling is lower than 3m

7: G = 7

8: C = 18

9: p + 18 = 41; p = 23

10: D = 100t

Step-by-step explanation:

Question 1:

5*2+x/2-7

5*2+6/2-7

10+6/2-7

10+3-7

13-7

Question 2:

4*2<16

8<16 True

4*1<16

4<16 True

4*3<16

12<16 True

4*4<16

16<16 False

Question 3:

Let's plug in 1 for m

4*1-1____5*1-4

4-1_____5-4

3_____1

3>1

Question 4:

You did not give an equation, so I cannot answer.

Question 5:

2*11 + 5 =27

22 + 5 = 27

27 = 27

So n = 11

Question 6:

x<3

The ceiling is lower than 3m because x<3

Question 7:

5.1g = 35.7

5.1g/5.1=35.7/5.1

g = 7

Check: 5.1 * 7 = 35.7

Question 8:

36 + c = 54

36 + c -36 = 54 - 36

c = 18

Check: 36 + 18 = 54

Question 9:

p + 18 = 41; p = 23 is correct because the number of paperback books plus the number of hardcover books would equal the total number of books sold. Check: 23 + 18 = 41

Question 10:

d=100t is correct because each time t goes up one it goes up 100. Example: if it is at one hour, than it is 100, if it is at 3 hours, than d = 100*3 = 300, which is the same pattern as the table.

Hope this helps!

A candy manufacturer is interested in the distribution of colors in each of its packages of candy sold. The manufacturer randoml

Otrada [13]

Answer:

Option B

Step-by-step explanation:

Given that a candy manufacturer is interested in the distribution of colors in each of its packages of candy sold. The manufacturer randomly sample packages from multiple batches at one factory.

Because he resorts to only one factory, there may be bias in the sample. Other factories may have different processes of the settings and also if a diversified sample is taken then it is likely to represent the whole population, and hence results would be more accurate

Option A is incorrect since only one factory was done

C and D are not selected because one factory result cannot be generalised to all other factors in the same country or outside.

So answer would be

B) No, because the other factories may have different processes or the settings

Two radar stations 5.5 miles apart are tracking an airplane. The straight line distance

Vesnalui [34]

Answer:

19°

Step-by-step explanation:

I have attached an image showing this elevation.

From the image, let's first find the angle A by using cosine rule.

Thus;

8.1² = 5.5² + 13.1² - 2(5.5 × 13.1)cos A

65.61 = 30.25 + 171.61 - 144.1cos A

144.1cos A = 171.61 + 30.25 - 65.61

144.1cosA = 136.25

cosA = 136.25/144.1

cosA = 0.9455

A = cos^(-1) 0.9455

A = 19°

Find all integers $n$ such that the quadratic $7x^2 + nx - 11$ can be expressed as the product of two linear factors with intege

disa [49]

Answer:

The all integer values of n are -76, -4, 4, 76

Step-by-step explanation:

∵ The factors of 7 are 1 and 7

∵ The factors of 11 are 1 and 11

- The last term of the quadratic is negative, that means the two

linear factors have different middle sign

∴ The factors are (7x ± 1)(x ± 11) OR (7x ± 11)(x ± 1)

Let us take one by one

The middle term of the quadratic is the sum of the product of nears and ext-reams

In (7x + 1)(x - 11)

∵ The product of ext-reams is 7x × -11 = -77x

∵ The product of nears is 1 × x = x

∵ Their sum is -77x + x = -76x

∴ n = -76

In (7x - 1)(x + 11)

∵ The product of ext-reams is 7x × 11 = 77x

∵ The product of nears is -1 × x = -x

∵ Their sum is 77x + -x = 76x

∴ n = 76

In (7x + 11)(x - 1)

∵ The product of ext-reams is 7x × -1 = -7x

∵ The product of nears is 11 × x = 11x

∵ Their sum is -7x + 11x = 4x

∴ n = 4

In (7x - 11)(x + 1)

∵ The product of ext-reams is 7x × 1 = 7x

∵ The product of nears is -11 × x = -11x

∵ Their sum is 7x + -11x = -4x

∴ n = -4

The all integer values of n are -76, -4, 4, 76
