Answer:
So actually #1 is answer. Thats because if we see last one it doesn't have a right angle but the original does. In the next one the angles dont match. The 23 and 67 degree angles are not in the original figure. We can see that the last one has those angles and the sides are switched and just multiplied by 2.

#1 is the answerPLEASE HELP IM DESPERATE IVE BENN WORKING ON THIS FOR THE PAST 48 HOURS I AM MARING BRAINIEST!: A constructor is measuring the perimeter of a plot for a building. 31% of the way around the perimeter, the constructor has measured 14 meters. How far around is the entire perimeter? Round your answer to the nearest hundredth.
Answer:
P = 45.16 meters
Step-by-step explanation:
Let the perimeter by P
31% of P is 14 meters
P*31% = 14 meters
Change to decimal form
P*.31 = 14
Divide each side by .31
P*.31/.31 = 14/.31
P =45.16129032
Rounding to the nearest hundredth
P = 45.16 meters
Suppose students are independent from one another. 63% of students are using Mr. Martin's new social media app, Mar-tin-stagram. 2 students are randomly selected. What is the probability that both of them use it?
Answer:
Probability that both of them use it = 0.3945
Step-by-step explanation:
Given:
Student use app = 63%
Number of chosen student = 2
Computation:
Assume total number of student = 100%
So, probability that both of them use it.
⁶³C₂ / ¹⁰⁰C₂

Answer:
The data table is attached below.
Step-by-step explanation:
The average of a set of data is the value that is a representative of the entire data set.
The formula to compute averages is:
[tex]\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}[/tex]
Compute the average for drop 1 as follows:
[tex]\bar x_{1}=\frac{1}{3}\times[10+11+9]=10[/tex]
Compute the average for drop 2 as follows:
[tex]\bar x_{2}=\frac{1}{3}\times[29+31+30]=30[/tex]
Compute the average for drop 3 as follows:
[tex]\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33[/tex]
Compute the average for drop 4 as follows:
[tex]\bar x_{4}=\frac{1}{3}\times[102+100+98]=100[/tex]
Compute the average for drop 5 as follows:
[tex]\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67[/tex]
The data table is attached below.
The average of the numbers in the data table will be 10, 30, 59.33, 100, and 124.67.
How to explain the data table?The average for drop 1 will be:
= 1/3 × (10 + 11 + 9)
= 10
The average for drop 2 will be:
= 1/3 × (29 + 31 + 30)
= 30
The average for drop 3 will be:
= 1/3 × (59 + 58 + 61)
= 59.33
The average for drop 4 will be:
= 1/3 × (102 + 100 + 98)
= 100
The average for drop 5 will be:
= 1/3 × (122 + 125 + 127)
= 124.67

Drag vertices B and C of the triangle. Then, conjecture about the relationship between angle measures and side lengths in a triangle.
If the angle measure is the largest of the triangle, what do you know about the side opposite?
It is the length.
If a side is the shortest of the triangle, what do you know about the angle opposite that side?
It is the degree measure
Answer:
1. longest
2. smallest
For the triangle mentioned here, the following is what will be obtainable based on the conjecture about relationship between sides and angle measures of a triangle:
You will know that for the largest angle measure, the side opposite the angle will be the longest side.You will know that for the shortest side in the triangle, the angle opposite it will be the smallest angle measure.Recall the conjecture about the relationship between the sides and angles of a triangle:

The arithmetic sequence a; is defined by the formula:
a1=4
ai = ai-1 + 11
Find the sum of the first 650 terms in the sequence.
Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775
The FDA regulates that fresh Albacore tuna fish contains at most 0.82 ppm of mercury. A scientist at the FDA believes the mean amount of mercury in tuna fish for a new company exceeds the ppm of mercury. The hypotheses are: H0:µ = 0.82 H1:µ > 0.82 What is a type II error in the context of this problem? A. The fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury. B. The fish is accepted by the FDA when in fact it had less than 0.82 ppm of mercury. C. The fish is rejected by the FDA when in fact it had less than 0.82 ppm of mercury. D. The fish is rejected by the FDA when in fact it had more than 0.82 ppm of mercury.
Answer:
Option A
Step-by-step explanation:
A type II error occurs when the researcher fails to reject the bull hypothesis when it is false.
In this study, the
null hypothesis is H0:µ = 0.82 while the alternative hypothesis is H1:µ > 0.82
Thus, the type II error will be that the fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury.

Answer:
I think the answer is C. 324 but i'm not sure. lemme know if i'm wrong and what the correct answer is
Step-by-step explanation:
The area of the given Circle C is; 324π
What is the area of the circle?
From the attached diagram, we see that;
WX is the radius of circle X and is equal to 8 units
Similarly, ZY is radius of circle Y and is equal to 10 units.
Thus, diameter of circle X = 8 * 2 = 16 units
Diameter of circle Y = 10 * 2 = 20 units
Thus;
Diameter of circle C = 20 + 16 = 36 units
Area of Circle C = π * 36²/4

Step-by-step explanation:
how many cylindrical glasses 6cmin diameter and 10cm deep can be filled from cylindrical jug 10cm in diameter and 18cm deep
Answer:
Step-by-step explanation:
So we need to divide the volume of the cylindrical glasses by the cylindrical jugs to see how many we can fill.
The equation to find the volume of a cylinder is Height*Area of Circle
To find the area of a circle is: [tex]\pi r^{2}[/tex]
In this senario "r" (radius) is 3 (d/2)
Volume for cylindrical glass:
hx[tex]\pi r^{2}[/tex]
= 10x 3.14x 3^2
= 10x3.14x 9
= 282.6[tex]cm^{3}[/tex]
Now for the cylindrical jug: r= 5 and h=18
hx[tex]\pi r^{2}[/tex]
= 18x3.14x5^2
= 18x3.14x25
= 1413[tex]cm^{3}[/tex]
Now finally we divide them:
1413/282.6
= 5
So they can fill 5 cylindrical glasses :)

If x represents the length of the first piece, find the lengths of all three pieces. what is the length of the first piece, the second piece, and third piece?
Answer:
Step-by-step explanation:
let length of first piece = x in
length of second piece = 2x
length of third piece = 5x
x+2x+5x= 16
8x =16
x =16/8
x=2
length of :
first piece =2 inches
second piece = 4 inches
third piece = 10 inches..
please mark me as the brainliest..
Answer:
2, 4, 10 in
Step-by-step explanation:
The first piece is x thus the second piece is 2x ( twice as long as first ) and
the third piece is 5x ( five times as long as the first )
Add the 3 together and equate to 16
x + 2x + 5x = 16, that is
8x = 16 ( divide both sides by 2 )
x = 2
Thus
first piece = x = 2 in
second piece = 2x = 2 × 2 = 4 in
third piece = 5x = 5 × 2 = 10 in
which equation be used to find the surface area of the cylinder
