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
The answer of 4.38 x 10^4 in ordinary notation is

simplify the variable expression: g-16/4
Answer:
im not sure if this is what ur looking for but id k hopefully yes
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).

Quadrilateral ABCD is similar to quadrilateral EFGH. Find the measure of side EF
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.
Mrs. Golden wants to cover her bulletin board that is 6.5 feet long and 4 feet tall. if she using 1
foot squares to cover the board, how many squares will she need?
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

use division to rename each fraction given below 12/20
Answer:
[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]

Jules owns a square plot of land that measures 30 yards on each side. He plans to divide the land in half by building a fence as shown by the dotted line below. how many yards of fencing does Jules need
A 15yd
B 30 yd
C 30/2yd
D30/2yd
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

i need help now, The rectangle and the trapezoid have the same area. What is the length l of the rectangle?
Answer:
The I is 12.
Step-by-step explanation:
You dont count the slang when you are finding the area, im not good at explaining but its basically just 12x9. 12x9=x. X is the area- aka 108. Divide 108 by the 9 in the rectangle. IM BAD AT EXPLAINING SORRY
Answer:
36
Step-by-step explanation:
(figure out length of triangle)24-12=12
(find full length of base which is equal to L of rectangle)24+12=36
Battery life for a hand-held computer is normally distrituted and has a population standard deviation of 7 hours. Suppose you need to estimate a confidence interval estimate at the 95% level of confidence for the mean life of these batteries. Determine the sample size required to have a margin of error of 0.585 hours. Round up to the nearest whole number.
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.

The weight of a soccer ball is normally distributed with a mean of 0.43 kg and a standard deviation of 0.01 kg. Suppose 800 different soccer balls are in a warehouse. About how many soccer balls weigh more than 0.45 kg?
A. 12
B. 20
C. 24
D. 40
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
How many trucks carried only late variety?
How many carried only extra late?
How many carries only one type of peach?
How many trucks(in all) went out during the week?
9514 1404 393
Answer:
late only: 15extra-late only: 24one type: 43total trucks: 105Step-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

The sum of the interior angle measures of a convex polygon is 2520° . How many sides does it have?
Answer:
16
Step-by-step explanation:
number of sides = (sum of interior angles / 180) + 2
(2520 / 180) + 2 = 16 sides

A cylindrical soup can has a radius of 1.1 in. and is 5.4 in. tall. Find the volume of the can and round to the nearest tenths if necessary
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].
A population of 65 foxes in a wildlife preserve triples in size every 12 years. The function y = 65.3*, where x is the number of 12-year periods, models the population growth. How
many foxes will there be after 36 years?
After 36 years there will be foxes. (Type a whole number.)
Answer:
585 foxes
Step-by-step explanation:
36/12 = 3
That means there are 3 fifteen-year periods in 36 years.
So after 3 fifteen-year periods, there will be 65 × 3³ foxes
That is 75(27) foxes
585 foxes
ein rechteckiger Bauplatz ist 39,5 m lang und 32,5 m breit . wie teuer ist der Grund ,wenn ein Quadratmeter Bauland 185,50 euro kostet???
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!
