Hi!
Your answers should be : 1. Obtuse | 2. Acute | 3. Obtuse
Here's a little tip for you to remember if you cant get an answer off of brainly: if its 90ft (or degrees or what ever you want to call it) then its right, if its over 90ft its Obtuse, and if its under 90ft its Acute.
Hope this helps!
Let me know if you need anymore help!

~~~PicklePoppers~~~A new amusement-park ride that lasts 1 minute can have up to 1200 riders per hour. How many riders can ride per minute?
Answer:
20 riders can ride per minute.
Step-by-step explanation:
The picture says to divide to find the number of riders. If we apply this here, we can see that 1200 ÷ 60 is 20.
The reasoning behind this is:
There are 60 minutes in an hour.
If the park ride lasts a minute, then the ride can have 60 rides per hour.
The question states that the ride can have up to 1200 riders per hour, so you need to divide 1200 by 60.
1200 ÷ 60 = 20.

the sum of three numbers is 78. the third number is 2 times the second. the first number is 6 less than the second. what are the numbers
Solving Inequalities
-6x+2>20
Answer:
first you subtract 2 from both sides
-6x>18
then you divide
-6 by 18 which is -3 and since you divided with a decimal that flips your sign so your answer is X<-3
Answer:
x<-3
Step-by-step explanation:
First, write the equation and subtract 2 on both sides.
-6x+2>20
-2 -2
-6x>18
Divide both sides by -6.
-6x>18
/-6 /-6
x<-3
(Remember, we have to flip the sign when multiplying or diving by a negative.)

1) The Boateng family has a sickening house whose layout is shown
above. They would like to renovate just bedrooms #2 and 3. Because you
are a contractor, you receive 20% off from Home Depot whenever you
make any purchases. If Home Depot sells your client's ideal wool carpet
for $8.99 per square foot, how much will it cost to carpet both
bedrooms? (Keep in mind that 10'8" would be written as a decimal
approximation of 10.67 ft. Think about why this is.)
a) How many total square feet of carpeting will you need?
Answer:
The cost will be $1662.136
The total square ft of carpeting will be 231.1122ft^2
Step-by-step explanation:
For the bedrooms, the dimension from the image is shown as(see attahced)
Bedroom #2= 10"8' x10"4'
Bedroom #3= 10"8' x11"4'
let us convert all dimension to feet and solve for the area of the bedrooms
Bedroom #2= 10"8' x10"4'
Bedroom #2=10.67x10.33feet
Area of Bedroom #2= 110.2211ft^2
Bedroom #3 = 10"8' x11"4'
Bedroom #3 =10.67x11.33feet
Area of Bedroom #3= 120.8911ft^2
The total area of both rooms is
Total area=110.2211+120.8911
Total area=231.1122ft^2
now the cost of one square floor s $8.99
hence the cost of 231.1122ft^2 will be
Cost of carpet = 231.1122*8.99
Cost of carpet = $2,077.67
Given that, because you are a contractor, you will receive 20% off
therefore it will cost
= (20/100)*2,077.67
=0.2*2,077.67
=$415.534
The cost will now be $2,077.67-$415.534
= $1662.136

Answer:
Sam's thinking was incorrect.
On number first we have to move 10 units from 0 in positive direction after that negative sign means move in left direction.
But we have 2 negative signs so we need to move 6 units more on positive or right direct as shown below.

Does anyone know the differences and similarities between theorems and conjectures?
I searched on google but I didn’t understand! So in easy words please.. I’m sorry I’m dumb (;´༎ຶٹ༎ຶ`)
The difference between a theorem and a conjecture :-
Theorem :- Something which is true and can be proved .
I am giving a very simple example here .
Angle sum theorem :- sum of all angles in a triangle will be equal to 180° .
This is a theorem because every interior angle of a triangle will add up to 180° . It cannot change .
So , something that is definitely true and can be proved is a theorem .
Conjecture :- Something that is supposed to be true , but still hasn't been proved to be true .
Example :-
1a = 10
2a = 20
3a = 30
With this you can guess that 4a must be equal to 40 , but it can't be proved without using algebra .
Therefore , something which is likely to be true is a conjecture ( in maths ) .
What is 3/4 times 1/8=
Answer:
The answer should be 3/22.
Step-by-step explanation:
To multiply the fractions, multiply the numerators and denominators separately.
3 times 1 over 4 times 8,
Multiply straight across,
Answer should be 3/22
The 3/4 times 1/8 equals 3/32.
To calculate the product of fractions, you multiply the numerators together to get the numerator of the result, and multiply the denominators together to get the denominator of the result.
For 3/4 times 1/8:
Numerator: 3 × 1 = 3
Denominator: 4 × 8 = 32

Problem 4:
The hypotenuse of a right angled triangle is 20 cm. The difference between its other two sides is 4 cm. Find the length of the sides.
Answer:
12cm and 16cm
Step-by-step explanation:
The hypotenuse of the right angle triangle = 20cm
let the other two sides be x and y;
The difference;
x = y - 4
Problem:
Find x and y;
Solution:
According to the pythagoras theorem;
x² + y² = 20² ------ i
x² + y² = 400 ----- i
and x - y = 4 ---- ii
So; x = 4 + y
Now input the value into equation (i);
(y + 4)² + y² = 400
(y+4)(y+4) + y² = 400
y² + y² + 4y + 4y + 16 = 400
2y² + 8y + 16 = 400
2y² + 8y + 16 -400 = 0
2y² + 8y - 384 = 0;
y² + 4y - 192 = 0
Factorize the equation;
y² + 16y - 12y - 192 = 0
y(y + 16) - 12(y + 16) = 0
(y-12)(y + 16) = 0
y -12 = 0 or y+ 16 = 0
y = 12 or -16
It is not realistic for the length of a body to be a negative value, so y= 12;
since;
x - y = 4,
x = 4 + 12
x = 16

The formula for the density of a bacteria population is \dfrac NA A N start fraction, N, divided by, A, end fraction where there's an average of NNN bacteria in an area size AAA. Guang and Orion are doing an experiment in school for which they need to measure the density of a bacteria population after a certain solution has been introduced. Guang reports a density of 450045004500 bacteria per square centimeter and Orion reports a density of 505050 bacteria per square millimeter. Which one reports a higher density? Choose 1 answer:
Answer:
Guang reports a higher density of 4.5 × 10⁷ bacteria/m²
Step-by-step explanation:
Since Guang reports a density of 4500 bacteria per square centimeter and Orion reports a density of 50 bacteria per square millimeter, we convert both densities into bacteria per square meter to compare their values.
So, for Guang 4500 bacteria/cm² = 4500 bacteria/cm² × 10⁴ cm²/1 m² = 4500 × 10⁴ bacteria/m² = 4.5 × 10⁷ bacteria/m²
For Orion 50 bacteria/cm² = 50 bacteria/cm² × 10⁴ cm²/1 m² = 50 × 10⁴ bacteria/m² = 5 × 10⁵ bacteria/m²
Since 4.5 × 10⁷ bacteria/m² > 5 × 10⁵ bacteria/m², Guang reports a higher density of 4.5 × 10⁷ bacteria/m²
Answer:
B.) orion reports a higher desity than guang
Step-by-step explanation:
We found that Guang's reported density is 45 bacteria/ millimeter^2, while orion's reported density is 50 bacteria/ millimeter^2.
Calculate Social Security taxes, Medicare taxes, and FIT for Jordon Barrett. He earns a monthly salary of $13,400. He is single and claims 1 deduction. Before this payroll, Barrett’s cumulative earnings were $128,120. (Social Security maximum is 6.2% on $128,400 and Medicare is 1.45%.) Calculate FIT by the percentage method.
Answer:
Step-by-step explanation:
From the given information:
Social security taxes can be calculated as:
$128,400 - $128,120
= $280
Also, we know that the current monthly salary = $13, 400
So, social security tax is withheld by $280
This implies that:
Social security taxes = 280 × 0.062
= $17.36
The medical care taxes will now be:
= $13,400 × 1.45%
= $194.30
Using the percentage method to calculate the federal income tax; we have:
Use the tax bracket from 2017, marginal tax rate = 28%
∴
federal income tax = $13400 × 0.028
federal income tax = $3752
