Answer:

14

Step-by-step explanation:

The internal angle sum of a 4 sided polygon is 360 so set it equal to 360. 5x+110+110+70=360

5x+290=360

5x=70

x= 14

Answer:

150

Step-by-step explanation:

Area of A:

A = bh

A = 10(10)

A = 100

Area of B:

A = 1/2bh

A = 1/2(10)(10)

A = 5(10)

A = 50

Combined:

100 + 50

150

Answer:

EF = 6.6

Step-by-step explanation:

Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.

Answer:

BD = 30√2 yd

Step-by-step explanation:

The shape of the land is a square with 30 yd side length on each side.

The fence to he built is the diagonal of the square BD.

Apply pythagorean theorem to find the number of yards of fencing (BD) he needs.

Thus:

BD² = BC² + CD²

BD² ° 30² + 30²

BD² = 1800

BD = √1800

BD = √(900*2)

BD = 30√2 yd

Answer:

C) 84 cm²

Step-by-step explanation:

The question is asking for the surface area of the square pyramid. So we need to get the area of all the surfaces, then add them together.

6 cm × 6 cm = 36 cm²

1/2(6 cm × 4 cm) = 12 cm² (There are 4 of these sides)

12 cm² + 12 cm² + 12 cm² + 12 cm² + 36 cm² = 84 cm²

So first you need to find the area of the building site which is:

length x width

39.5m x 32.5m

= 1283.75[tex]m^{2}[/tex]

We know that one square meter costs 185.50 euros.

1[tex]m^{2}[/tex] = 185.50 euros

1283.75[tex]m^{2}[/tex] = 238135.625 euros

I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are 238134.86 and 238135.86.

sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!

Answer:

A sample size of 551 is required.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Population standard deviation of 7 hours.

This means that [tex]\sigma = 7[/tex]

Determine the sample size required to have a margin of error of 0.585 hours.

This is n for which M = 0.585. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.585 = 1.96\frac{7}{\sqrt{n}}[/tex]

[tex]0.585\sqrt{n} = 1.96*7[/tex]

[tex]\sqrt{n} = \frac{1.96*7}{0.585}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*7}{0.585})^2[/tex]

[tex]n = 550.04[/tex]

Rounding up(as for a sample of 550 the margir of error will be a bit above the desired target):

A sample size of 551 is required.

Answer:

3c + 43 >_ 100

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the expression for calculating the sum of an AP as:

Tn = Sn - Sn-1

When n = 10

T10 = S10 - S9

Given that;

Sn = n²-3n

S10 = 10²-3(10)

S10 = 100 - 30

S10 = 70

S9 = 9² - 3(9)

S9 = 81 - 27

S9 = 54

Substitute the given values

T10 = S10 - S9

T10 = 70 - 54

T10 = 16

Hence the 10th term of the sequence is 16

Answer:

Answer is b) 20.

Step-by-step explanation:

Mean is 0.43 kg.

0.43+0.1+0.1= 0.45

0.45 is two standard deviation above.

All that are below mean is 50%,

Two standard deviation above is 95%/2=47.5%

50%+47.5% =97.7% are  balls that are less than 0.45 kg.

100%-97.7%=2.5% balls that are more than 0.45 kg

2.3%=0.025

800*0.025 = 20 soccer balls weigh more than 0.45 kg

Answer:

[tex]V=20.52\ in^3[/tex]

Step-by-step explanation:

Given that,

The radius and the height of the cylindrical soup can are 1.1 inch and 5.4 inch.

We need to find the volume of the can.

The formula for the volume of the can is given by :

[tex]V=\pi r^2 h\\\\V=\pi \times (1.1)^2 \times 5.4\\\\V=20.52\ in^3[/tex]

So, the volume of the can is equal to [tex]20.52\ in^3[/tex].

Answer:  26

Step-by-step explanation:

6.5 feet long and 1-foot square means 6.5 (6 and 1 half) squares in length

4 feet tall, 6.5 times 4 (length times width) to equal 26 feet

if it's 26 feet, that means it will use 26 of the 1-foot squares

Step-by-step explanation:

-16/4=-4

g-4

The solution after simplifying the variable expression by evaluating its numerical part is (g - 4).

Given that,

The expression is,

[tex]g - \dfrac{16}{4}[/tex]

Used the concept of expression by combining the like terms.

Now, simplify each term as,

[tex]g - \dfrac{16}{4}[/tex]

Here, [tex]\dfrac{16}{4} = 4[/tex]

So, we get;

[tex]= g - 4[/tex]

Therefore, the solution is (g - 4).

[tex]Fraction = \frac{3}{5}[/tex]

Step-by-step explanation:

Given

[tex]Fraction = \frac{12}{20}[/tex]

Required

Rename using division

This simply means that we reduce the fraction

So, we have:

[tex]Fraction = \frac{12}{20}[/tex]

Divide by 4/4

[tex]Fraction = \frac{12/4}{20/4}[/tex]

[tex]Fraction = \frac{3}{5}[/tex]

Answer:

Step-by-step explanation:

It works well when making a Venn diagram to start in the middle (6 carried all three), then work out.

For example, if 10 carried early and extra-late, then only 10-6 = 4 of those trucks carried just early and extra-late.

Similarly, if 30 carried early and late, and 4 more carried only early and extra-late, then 38-30-4 = 4 carried only early. In the attached, the "only" numbers for a single type are circled, to differentiate them from the "total" numbers for that type.

__

a) 15 trucks carried only late

b) 24 trucks carried only extra late

c) 4+15+24 = 43 trucks carried only one type

d) 38+67+56 -30-28-10 +6 +6 = 105 trucks in all went out
