Answer:
48
Step-by-step explanation:
One nice, reliable thing about triangles is that their interior angles will ALWAYS add up to 180 degrees. So, if one angle is 43 degrees and the other angle is 48 degrees, we can see that
180 - 43 - 48 = 89
Now, the tricky part: how to determine which type of triangle this is.
An acute triangle is one in which all interior angles are less than 90 degrees. An isoceles triangle is one in which two of the interior angles are the same, while the third is different. An obtuse triangle is one in which one of the interior angles is greater than 90 degrees. A right triangle is one in which one of the interior angles is equal to 90 degrees.
We distinguish between these different types because they each have useful, but different, properties.
By these definitions, it is clear that the triangle in question is acute.

Step-by-step explanation:
The Athens-Clarke Country Wildlife Resource Center wanted to encourage wildlife preservation efforts among students in its summer camp. In the past, it would run a particular curriculum, then gauge students' interest in wildlife preservation in a test at the end of the camp. Historically, the average on this final test to gauge preservation interest was 35.3 (out of 100).
Last summer, the resource Center created a new curriculum focusing on campers interacting directly with wildlife to promote preservation efforts. This included efforts in species dentrication handling of wild animals, and directoration of animals in habitat The Resource Center considers the collection of 40 to be a random samping from the population of campers they will encounter They need your help to determine whether this new curriculum Improves impressions about witte preservation. For their 40 scores at the end of lut summer, they found a sample mean of 26.58 and a standard deviation of 3.18.

What are the null and alternative trypotheses?
Answer:
H0 : u ≤ 0.353
Ha: u > 0.353
Step-by-step explanation:
The null and alternate hypotheses are formulated by the given claim. The claim is mostly set as the alternate hypothesis and the opposite of the alternate hypothesis is the null hypothesis.
In this question the given statement is the average on this final test to gauge preservation interest was 35.3 (out of 100). This can be used as the null hypothesis.
H0 : u ≤ 0.353
The claim is also given which is To test whether the new curriculum Improves impressions about witte preservation.
against the claim Ha: u > 0.353
Therefore it will be a one tailed test.
Kathy bought 5 pencils for the price of $6.30. Which equation represents r, the cost, in dollars, of each pencil?
A.r=6.30+5
B.r = 6.30÷5
C.r=6.30×5
D.r=6.30−5
9514 1404 393
Answer:
B. r = 6.30÷5
Step-by-step explanation:
The cost per pencil is found by dividing the cost by the number of pencils.
Here, the cost is $6.30 and the number of pencils is 5. Then the cost per pencil (r) is ...
r = 6.30 ÷ 5

Find the area of the composite figure
Rearrange
C=d+2/3
to make d the subject.
Answer:
d = C - 2/3
Step-by-step explanation:
Subtract 2/3 from both sides of the equation:
C = d + 2/3
-2/3 -2/3
-----------------
C - 2/3 = d
After rearranging the expression and taking the subject d is d = C - 2/3 or d = (3C-2)/3.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
C=d + 2/3
C - 2/3 = d (subtract both side by 2/3)
or
d = C - 2/3 or
d = (3C-2)/3
Thus, after rearranging the expression and taking the subject d is d = C - 2/3 or d = (3C-2)/3.

Answer:
7)Bagel costs $3.5 and muffin cost $1.25
8) Ticket is $9 while snacks are $2
9) Correct because left hand side is zero
10) Correct because they both have same slope and same y-intercept
Step-by-step explanation:
7) Let bagel be x and muffin be y.
Thus;
For Aaron;
x + 3y = 7.25 - - - (1)
For bee;
x + 2y = 6 - - - (2)
Subtract eq 2 from eq 1 to get;
y = 1.25
Put 1.25 for y in eq 2;
x + 2(1.25) = 6
x + 2.5 = 6
x = 6 - 2.5
x = 3.5
Bagel costs $3.5 and muffin cost $1.25
8) Let movie ticket be x and snacks be y.
Thus;
2x + 3y = 24 - - - (1)
3x + 4y = 35 - - - (2)
Multiply eq(1) by 3 and eq(2) by 2 to get;
6x + 9y = 72 - - - (3)
6x + 8y = 70 - - - (4)
Subtract eq 4 from eq 3 to get;
y = 2
Put 2 for y in eq 3;
6x + 9(2) = 72
6x + 18 = 72
6x = 72 - 18
6x = 54
x = 54/6
x = 9
Ticket is $9 while snacks are $2
9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.
Thus, no solution exists because we can't isolate the variable to get an answer.
10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.
In this case, their y-intercept which is when x is 0 is;
3(0) + y = 9
y = 9
Their slope is also the same equal to 3.

A rocket is launched from atop a 74-foot cliff with an initial velocity of 113 ft/s. The height of the rocket above the ground at time t is given by h=16t^2+113t+74. When will the rocket hit the ground after it is launched? Round to the nearest tenth of a second.
9514 1404 393
Answer:
7.7 seconds
Step-by-step explanation:
The solution is given by the quadratic formula.
For ax² +bx +c = 0, the roots are ...
x = (-b±√(b²-4ac))/(2a)
We want the positive root, so ...
x = (-113 -√(113² -4(-16)(74)))/(2(-16)) = (113 +√17505)/32 ≈ 7.6658
The rocket will hit the ground about 7.7 seconds after it is launched.

m2 = 165
X is a discrete random variable. The graph below defines a probability distribution for X.
What is the expected value of X?
Answer: 1.1
Step-by-step explanation:
Expected value is the weighted average of the various possibilities and their probability of occurring.
The probabilities represented are:
0.35, 0.35, 0.15 and 0.15.
They add up to:
= 0.35 +0.35 + 0.15 + 0.15
= 1
The possibilities are; 0, 1, 2 and 3.
Expected value = (0.35 * 0) + (0.35 * 1) + (0.15 *2) + ( 0.15 * 3)
= 1.1

Which is bigger? 92^7 or 3^81? Hint: can you write 9^27 as an exponential expression with a base of 3?
Answer:
[tex] {3}^{81}[/tex] is bigger.
Step-by-step explanation:
[tex] {9}^{27} = ( {3}^{2} )^{27} = {3}^{2 \times 27} = {3}^{54} \\ [/tex]
If we compare the exponents of [tex] {3}^{54}[/tex] and [tex] {3}^{81}[/tex] it can be concluded that:
[tex] {3}^{81}[/tex] > [tex] {3}^{54}[/tex]
