If one acute angle of a right triangle measures 17°, what is the measure of the other acute angle?
A 67
B 77
C 73
C 63
Answer:
C. 73
Step-by-step explanation:
Triangles add up to 180 degrees.
180-90(right angle)-17 = 73 degrees
73<90 so it is acute.
Juan and Franco collect baseball cards. Juan has baseball cards. Franco has 18 fewer baseball cards than Juan. Together they have 150 baseball cards. How many baseball cards does Franco have?
Answer:
Franco has 66 baseball cards.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of baseball cards that Franco has.
y is the number of baseball cards that Juan has.
Franco has 18 fewer baseball cards than Juan.
This means that:
[tex]x = y - 18[/tex]
Also:
[tex]y = x + 18[/tex]
Together they have 150 baseball cards.
This means that:
[tex]x + y = 150[/tex]
Since [tex]y = x + 18[/tex]
[tex]x + x + 18 = 150[/tex]
[tex]2x = 132[/tex]
[tex]x = \frac{132}{2}[/tex]
[tex]x = 66[/tex]
Franco has 66 baseball cards.
11. John is building a wall. When he uses 750 bricks, the wall is 6 metres long and 1.25m high.
John wants the finished wall to be 10 metres long and 1.25 metres high.
How many more bricks does John need to finish the wall?
(Total 3 marks)
Answer:
750 blocks = 6m long
x blocks = 10m long
750×10 = 6x
7500 = 6x
divide both sides by 6
7500/6 = 6x/6
1250 = x
x = 1250
.
. . 1250 blocks are needed to finish the wall of 10m long
What is 106% of = $7.95
Answer:
8.427
Step-by-step explanation:
7.95/x=100/106
(7.95/x)*x=(100/106)*x
7.95=0.94339622641509*x
(0.94339622641509) to get x
7.95/0.94339622641509=x
8.427=x
x=8.427
106% of 7.95=8.427

Answer:
A) 0

Step-by-step explanation:
A) −10 − 13 − 17 − (−40) [B.E.D.M.A.S rule] (First bracket)
= - 10 - 13 - 17 + 40
= 40 - 10 - 13 - 17. (Then subtraction)

= 0 (Ans)
B) 111 − (31 + 78) − 7 + 14 [B.E.D.M.A.S rule] (First bracket)
= 111 − 109 − 7 + 14. (Then addition)
= 111 + 14 - 109 - 7
= 125 - 116. (At last subtraction)
= 9 (Ans)

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 2,5,8,... ?
Answer:
Arithmetic sequence with common difference of 3.
Step-by-step explanation:
Arithmetic sequence:
The difference between consecutive terms is always the same, and this difference is called common difference.
Geometric sequence:
The quotient between consecutive terms is always the same, and this quotient is called common ratio.
In this question:
5 - 2 = 8 - 5 = 3
5/2 = 2.5 different of 8/5 = 1.6
This means that it is an arithmetic sequence with common difference of 3.

Find the slope of the line
Slope - m
Enter your answer as an integer or as a reduced fraction in the form A/B,
Check Answer
Answer:
m=-5/2
Step-by-step explanation:
Two points on the line are (-2, 1) and (0, -4).
So, we have to use the expression Δy/Δx to find the slope.
So, (1-(-4))/(-2-0)=5/-2=-5/2.
The slope of the line is -5/2
Here,
In the graph,
Two points on the line are (-2, 1) and (0, -4).
We have to find the slope of graph.
What is Slope?
A measure of its steepness is called the slope.
Now,
Two points on the line are (-2, 1) and (0, -4).
So, we have to use the formula of slope to find the slope.
Hence,
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
So, [tex]m = \frac{-4-1}{0-(-2)} = \frac{-5}{2}[/tex]
Therefore, The slope of the line is -5/2.

Write an equation in slope-intercept form
for a line that goes through the points
(-4, 6) and (3,9).
S CAR
Answer:
y = 3/7x + 54/7
Step-by-step explanation:
(not sure what S CAR is)
(-4, 6) & (3, 9)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(9 - 6) / (3 - (-4))
Simplify the parentheses.
= (3) / (3 + 4)
= (3) / (7)
Simplify the fraction.
= 3/7
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 3/7x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 3/7(3) + b
To find b, multiply the slope and the input of x(3)
9 = 9/7 + b
Now, subtract 9/7 from both sides to isolate b.
9 - 9/7 = b
[convert 9 to have a denominator of 7]
63/7 - 9/7 = b
54/7 = b
Plug this into your standard equation.
y = 3/7x + 54/7
This is your equation.
Check this by plugging in the other point you have not checked yet (-4, 6).
y = 3/7x + 54/7
6 = 3/7(-4) + 54/7
6 = -12/7 + 54/7
6 = 42/7
6 = 6
Your equation is correct.

A university health services physician is concerned about how much sleep freshmen are getting. She asks a simple random sample of 50 students if they got at least 8 hours of sleep the previous night. Then she constructs a 95% confidence interval for the true proportion of all freshman college students who got at least 8 hours of sleep the previous night
Answer:
c
Step-by-step explanation:
If the level of confidence falls to 90%, the length will likewise fall.
What is a Confidence interval?A confidence interval (CI) is a range of values that, with a particular level of certainty, is likely to encompass a population value. A population means that sits between an upper and lower interval is frequently stated as a percentage.
Let p be the proportion of students who gets at least 8 hours of sleep the previous night.
here, Sample size = n = 50
the 95% confidence interval for true proportion is,
P ± Zₐ/₂ * [tex]\sqrt{P{\frac{1-P}{n} }[/tex]
P ± 1.96 * [tex]\sqrt{P{\frac{1-P}{50} }[/tex]
95% confidence length = 2 *P ± Zₐ/₂ * [tex]\sqrt{P{\frac{1-P}{n} }[/tex]
= 2 * 1.96 * [tex]\sqrt{P{\frac{1-P}{50} }[/tex] = 3.92 * [tex]\sqrt{P{\frac{1-P}{50} }[/tex]
For 90% confidence length = 2 *P ± Zₐ/₂ * [tex]\sqrt{P{\frac{1-P}{n} }[/tex]
= 2 * 1.645 * [tex]\sqrt{P{\frac{1-P}{50} }[/tex] = 3.29 * [tex]\sqrt{P{\frac{1-P}{50} }[/tex]
Therefore, if the confidence level decreases to 90% then the length will also decrease.
