Directions: Find the surface area of each figure.
1.
20.7 in
4
11 in
11 in
Answer:
576.4 in²
Step-by-step explanation:
Surface area of square pyramid = Base Area + ½(perimeter of base)(slant height)
Base area = s² = 11² = 121 in.²
Perimeter of base = 4(11) = 44 in.
Slant height = 20.7 in.
Plug in the values
Surface area = 121 + ½(44)(20.7)
= 576.4 in²
The length of rectangular garden is 6 feet longer than the width. If the area of the garden is 16 square feet, find the length and width of the garden.
The length is __________ ft
The width is ___________ ft
Answer:
The length is 8 ft.
The width is 2 ft.
Step-by-step explanation:
A = l*w
l = w + 6
16 = w(w + 6)
16 = w^2 + 6w
w^2 + 6w - 16 = 0
(w + 8)(w - 2) = 0
w = -8ft or 2ft
Since lengths cannot be negative in reality, w = 2ft.
l*2 = 16
l = 8ft

7. Mrs. Paulson is constructing a 90% confidence interval for the difference of means based on independent
simple random samples from two populations. The sample sizes are n, = 6 and n, =14. She draws dotplots
of the sample data to check one of the conditions for using two-sample i procedures. Which of the following
descriptions of those dotplots would suggest that it is safe to perform inference?
(a) Both dotplots are roughly symmetric. There are no outliers in either dotplot.
(b) Both dotplots are roughly symmetric. The dotplot of sample 2 has an outlier.
(c) Both dotplots are strongly skewed to the right. There are no outliers in either dotplot.
(d) Both dotplots are roughly symmetric. Both dotplots have one upper outlier
(e) i procedures are not recommended in any of these cases.
The description that will show that it is safe to perform inference is that (a) Both dotplots are roughly symmetric. There are no outliers in either dotplot.
What description would make it possible to make inferences?In order to use the two-sample t procedure to make inferences, certain conditions need to be met such as the sample being random and independent.
The variances for the groups in the data need to be equal which is why the presence of no outliers in either dotplot would present an safe opportunity to be able to perform inferences on the data.
In conclusion, option A is correct.

Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
y=-16x^2+161x+108
y=−16x
2
+161x+108
Answer:
5.03secs
Step-by-step explanation:
Given the height reached by the rocket expressed as;
y = -16x^2 + 161x + 108
The rocket reaches it max height when its velocity is zero
Velocity is expressed as;
V(x) = dy/dx = 0
dy/dx = -32x + 161
0 = -32x + 161
32x = 161
x = 161/32
x = 5.03
Hence it will take 5.03secs for the rocket to reach its maximum height

Answer:
10 and 2
Step-by-step explanation:
Essentially, you're being asked to find factors of 20 that have difference of 8. 20 can be factored as ...
20 = 20×1 = 10×2 = 5×4
The factors 10 and 2 have a difference of 8.

Estimate the radius of the object
Answer:
r = 1.41 mm
Step-by-step explanation:
Given that,
The circumference of the flower, C = 8.9 mm
We need to find its radius. We know that,
Circumference, [tex]C=2\pi r[/tex]
Where
r is the radius of the object
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{8.9}{2\pi}\\\\r=1.41\ mm[/tex]
So, the radius of the object is equal to 1.41 mm.

a number line is divided into 8 equal parts to show eighths. A point is labeled 1/2. Name the equivalent fraction for the labeled point.
Answer:
4/8.
Step-by-step explanation:
4/8 is the correct answer for this question. This is why. If you take 8 and divide it in half, your answer will be 4. Also because fractions are division so the fraction 8/2 equals 4. This means the 1/2 mark is equal to 4.
An airliner travels 95 miles in 12 minutes. What is its speed in miles per hour?
Answer:
475 miles per hour
Step-by-step explanation:
the plane traveled 95 miles in 12 minutes. the first thing we need to do is determine how many 12 minutes go into 1 hour. 12 minutes is repeated 5 times in order to get a total of 60 minutes and 60 minutes is 1 hour. the final thing we need to do is multiply 95 by 5 to get the total number of miles per hour traveled. the total of that is 475 miles per hour which is the answer
written math;
60/12=5
95*5=475
answer= 475 miles per hour

The radius of the smaller circle is 6, and the longer segment adds up to 12 since 6 + 6 = 12. the area of the whole bigger circle would be 452.389, by using the formula of the area of a circle "πr²". This is what i can tell and the only part I'm confused in how to find the area of JUST the shaded part. I hope this helped a bit!

The area of the rectangle is 135/32 or 4 whole number 7/32 whose side measures are 2 whole 1/4 and 1 whole 7/8.
What is the area of the rectangle?It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.
The formula for finding the area of a rectangle is given by:
Area of rectangle = length × width
We have side measures of the rectangle:
[tex]\rm a = 2\frac{1}{4} \\\\\rm b = 1\frac{7}{8}[/tex]
The area of the rectangle A is given by:
[tex]\rm A = (2\frac{1}{4} )\times(1\frac{7}{8} )[/tex]
[tex]\rm A = (\frac{9}{4} )\times(\frac{15}{8} )[/tex]
[tex]\rm A = \frac{135}{32}[/tex] or
[tex]\rm A =4 \frac{7}{32}[/tex]
Thus, the area of the rectangle is 135/32 or 4 whole number 7/32 whose side measures are 2 whole 1/4 and 1 whole 7/8.
