a certain triangle has a 30 angle and a 60 angle which must be a true statement about the triangle
Answer:
the other side has an 90° angle , it must be an acute triangle
Step-by-step explanation:
a triangle has a total angle of 180°
So if one side has an angle of 60° and the other has an angle of 30°, the other side must be the substraction of both angles to the 180° sum
180° - 60° - 30° = 90°
Answer: The longest side is twice as long as the shortest side.
Select the correct answer for how you would rationalize the denominator for 1/√3?
You would multiply top and bottom by [tex]\sqrt{3}[/tex] to go from [tex]\frac{1}{\sqrt{3}}[/tex] to [tex]\frac{\sqrt{3}}{3}[/tex]
Multiplying a square root by itself is the same as squaring the value.
So, [tex]\sqrt{x}*\sqrt{x} = (\sqrt{x})^2 = x, \ \ \text{ when } x \ge 0[/tex]
Which is why we're able to get rid of the square root in the denominator. The square root and squaring operation effectively cancel each other out.

SHOW WORK: Evaluate f(-2) with f(x)=3x+1 *
Answer:
f(2) = 7
Step-by-step explanation:
Solve for f(-2) in f(x) = 3x + 1
x = -2
Plug in -2 for x in the equation:
f(2) = 3(2) + 1
Remember to follow PEMDAS. First, solve the multiplication, then add:
3 * 2 = 6
6 + 1 = 7
f(2) = 7 is your answer.

A university is proposing a new procedure for professors to gain tenure. To gauge sentiment about the proposal, the university intends to randomly sample five professors, five assistant professors, five associate professors, five adjunct professors, and five visiting professors. This is an example of what type of sampling design
Answer:
The correct answer is:
stratified sampling
Step-by-step explanation:
Stratified sampling is a type of sampling method where the population to be sampled is divided into subgroups or strata and then random selection is made, and these strata are formed based on some shared common characteristics. In this example, the population to be sampled is a population of professors, but the researcher went further to divide this group into professors, assistant professors, associate professors, adjunct professors, and visiting profesors.

The length of a rectangle is 4 more than twice the width. If this rectangle’s perimeter is 50,
what are its dimensions?
Answer:
width: 7 length: 18
Step-by-step explanation:
they tell us the length is 2 times the width plus 4 more so the equation for one of the lengths is
2x + 4, where 'x' is the value of one width. but, because there are two sides for each the length and the width, the final equation will be:
2(2x + 4) + 2(x) = 50
then simplify and solve for 'x'

Step-by-step explanation:
Arbaz's mom reminds him that he also needs to purchase car insurance. Arbaz finds a
car insurance policy that will cost him $150 a month for the first 12 months. The cost
is expected to decrease by 3.2% each year he has his license. How much is Arbaz
expected to pay, monthly, after one year? Show your work and explain your answer.
Answer:
Arbaz is expected to pay $145.2 every moth after one year.
Step-by-step explanation:
We know that 150 dollars is owed every month. And after every 12 months the cost he has to pay a month decreases by 3.2% meaning we have to find what 3.2% is of 150. So we convert 3.2 into a decimal getting us 0.032
150 x 0.032 = 4.8
Now we know what 3.2% is of 150 so we subtract 4.8 from 250 and get 145.2
150 - 4.8 = 145.2

1 9/10 + 3/4 plz need help I’m tired and can’t do math I also need it simplified
Answer:
4
Step-by-step explanation:
take 1 9/10 change it to 19/10 + 3/4. You will need to have a common denominator for any addition or subtraction with fractions. We multiply 19/10 by 4 to get 76/40. Multiply 3/4 by 10 to get 30/40. Now we have a common denominator.
Add across 76 + 30 = 106/40. Now simplify. How many times does 40 go into 106?
4 times. No remainder.

shoppers enter hamilton place mall at an average of 120 per hour what is the probability that at least 20 shoppers
This question is incomplete, the complete question is;
Shoppers enter Hamilton place mall at an average of 120 per hour
what is the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m.?
Answer:
the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m
is 4.20787 × 10⁻⁸ ≈ 0.0000000420787
Step-by-step explanation:
the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m;
interval between noon and 12:30 is 30min
now the shoppers enter an average of [(120 × 30) / 60] = 60 per 30min
so
P( 20 ≤ X ≥ 23 ) = P( X=20 ) + P( X=21 ) + P( X=22 ) + P( X=23 )
= [(e⁻⁶⁰(60)²⁰) / 20!] + [(e⁻⁶⁰(60)²¹) / 21!] + [(e⁻⁶⁰(60)²²) / 22!] + [(e⁻⁶⁰(60)²³) / 23!]
= [1.3159 × 10⁻⁹] + [3.7598 × 10⁻⁹] + [1.0254 × 10⁻⁸] + [2.6749 × 10⁻⁸]
= 4.20787 × 10⁻⁸ ≈ 0.0000000420787
therefore the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m is 4.20787 × 10⁻⁸ ≈ 0.0000000420787

Answer:
x = 75° and y = 105°
Step-by-step explanation:
In the given figure
There are two parallel lines intersected by another line which called a transversalThere are two corresponding angles formed from this situation∵ The angle of measure (180 - x) and the angle of measure y are
corresponding angles
∵ Corresponding angles are equal in measures
→ Equate their measures
∴ 180 - x = y ⇒ (1)
The down line and the transversal formed a pair of linear angles at the point of intersection∵ The angle of measure y and the angle of measure 75° are linear angles
∵ The sum of the measures of the linear angles is 180°
→ Add their measures and equate the sum by 180°
∴ y + 75 = 180
→ Subtract 75 from both sides to find y
∵ y + 75 - 75 = 180 - 75
∴ y = 105°
→ Substitute the value of y in (1)
∵ 180 - x = 105
→ Subtract 180 from both sides
∵ 180 - 180 - x = 105 - 180
∴ - x = - 75
∵ Divide both sides by -1 to find x
∴ x = 75°
