I got 98 for first and 31 for second(ik i'm probably wrong-_-)
Answer:
9. 149 degrees
10. 2 units
Step-by-step explanation:
9. These two triangles are congruent, which means their corresponding side lengths and angles are are equal.
Here, the angle on the bottom triangle marked x actually corresponds to the angle in the top triangle that is unlabelled. That means if we find the unlabelled angle in the top triangle, we've found x.
All angles of a triangle add up to 180, so we can write: x + 17 + 14 = 180
Solve for x: x = 180 - 17 - 14 = 149 degrees
10. Similar triangles have their corresponding angles the same and their corresponding sides in the same ratio, not the same length this time.
Notice that RP is the long leg of triangle PQR and that AC is the long leg of triangle ABC, which means that they correspond to each other and we can write the ratio: RP / AC = 16 / x.
Notice that QP is the short leg of triangle PQR and that AB is the short leg of triangle ABC, which means that they correspond to each other and we can write the ratio: QP / AB = 8 / 1.
Now we can set these two ratios equal and solve for x:
16/x = 8/1
8x = 16
x = 2 units
Answer:
9. 149°
10. 2
Step-by-step explanation:
Congruent figures have the same angles and lengths
x = 180 - 17 - 14
x = 149°
Similar figures have sides in the same ratio
1/8 = x/16
x = 16/8
x = 2

population of each insect species in millions, and y represent the elapsed time in years. Which equation can be used to

what is 0.006772 rounded to 1 significant figure?
and whats the method to doing it?
Answer:
0.007
Step-by-step explanation:
( 0.006) 6 is the first significant number.
The number next to it is seven. (0.0067) in which 7 is greater than 5.
therefore, add 1 .
the final answer is 0.007
0.006772 rounded to 1 significant figure is 0.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, 0.006772 and we'll round this to 1 significant figure means only one digit it will have after the decimal place.
So, 0.006772
= 0.006770
= 0.00677
= 0.00680
= 0.00700
= 0.007
= 0.010
= 0.01
= 0.00
= 0.

Step-by-step explanation:
Volume of a shape
Jacob’s dad gave him a soda can to use. He was able to cut off the top to have a full opening. The can is 5 inches tall and the opening has a diameter of 3 inches.
Jacob’s little sister ate her ice cream, but didn’t want to eat the cone. Jacob decided to use the cone to scoop sand and build his castle. The cone is 5 inches long and has an opening diameter of 3 inches
Answer:
The can's volume is 35.34 inches
the cone's volume is 11.78 inches
hope it helps you!!
The question asks for the volume of a cylinder and a cone, both with a height of 5 inches and a diameter of 3 inches. The volume of the cylinder is calculated as approximately 35.34 inches³, and the volume of the cone is about 11.78 inches³.
The question involves finding the volume of two different 3-dimensional shapes: a cylinder (soda can) and a cone (ice cream cone). To calculate the volume of the cylinder, we use the formula V = π r² h, where r is the radius of the circular base, and h is the height of the cylinder.
Since the diameter of the soda can is given as 3 inches, the radius (which is half of the diameter) would be 1.5 inches. For the cone, the formula for volume is V = {1}/{3} π r² h, using the same measurements for r and h as the soda can. The calculations then proceed as follows:
Cylinder: V = π (1.5)² × 5 = π × 2.25 × 5
Cone: V = {1}/{3} π (1.5)² × 5 = {1}/{3} π × 2.25 × 5
The volume of the cylinder would be approximately 35.34 inches³ and the volume of the cone would be about 11.78 inches³, assuming π is approximately 3.14159.

what percent of 3,201= 2,750
Answer:
86%
Step-by-step explanation:
1) divide 2750 by 3201 to get a part/whole ratio for a percent
2) divide and get 85.91%
Answer:
x = 85.9%
Step-by-step explanation:
Step 1: Make an equation
[tex]3201 * x = 2750[/tex]
[tex]3201x = 2750[/tex]
Step 2: Divide both sides by 3201
[tex]3201x / 3201 = 2750 / 3201[/tex]
[tex]x = 0.859...[/tex]
Step 3: Convert to percentage
[tex]x = 0.859... * 100[/tex]
x = 85.9%
Answer: x = 85.9%
How many ways can a committee of 4 people be chosen from a group of 8 people if the members are selected in no particular order?
Answer:
70
Step-by-step explanation:
There are 8 choices for the first member, 7 for the second, 6 for the third, and 5 choices for the fourth member (because once you pick someone as a member, they cannot be picked again)
So you have:
8*7*6*5 = 1680
However, we realize that in this particular problem, order DOES NOT matter. (for example, ABCD is the same as DCBA.)
So we divide 1680 by 4! (4*3*2*1) to end up with 70.
You do this because because there are 4! ways to arrange 4 people in a line, and since order doesn't matter, only one of those arrangements counts.

PLEASE HELP!! The mean absolute deviation for each pizzeria is approximately 10. Approximately how many times the mean absolute deviation is the difference between the means of the data sets?
The required mean absolute deviation is 2.1 times the difference between the means of the data sets.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
To find the means of the two data sets, we need to convert the double stem-and-leaf plots into regular frequency distributions.
To calculate the mean of this data set, we can use the formula:
Mean of Giavano's = (sum of values) / (number of values)
Mean = [31+32+33+36+42+44+46+52+63+68+]/10
Mean= 44.7
Mean of brick oven = (sum of values) / (number of values)
Mean = 38+57+58*2+66+69+74+77+78+79 / 10 = 65.5
Difference of the mean = 65.5-44.7
MAD = 10
According to the question, a ratio of the difference of mean to MAD,
= 65.5 - 44.7 / 10 = 2.1
Thus, the required mean absolute deviation is 2.1 times the difference between the means of the data sets.

is the area of its base? (Round to the nearest tenth)
Answer:
1) The height of the prism is 8 units.
2) The area of its base is 27 square cm.
Step-by-step explanation:
The formula of a rectangular prism is
[tex]\text{Volume}=\text{Area of base}\times \text{Height}[/tex]
1) Given : The area of the base of a rectangular prism is 225 units square If the volume is 1800 cubic units.
To find : What is the height of the prism?
Solution :
Volume = 1800 cubic units
Area of base = 225 units square
Substitute the value,
