Answer:
367.5 square feet
Step-by-step explanation:
So, we know that for 1 inch on a bluesheet its 7 feet in a room.
We know area is L*W.
We know one length is 2.5in, and the other is 3in
lets convert this using the 1in:7ft ration above:
2.5*7ft
=
17.5ft
3*7ft
=
21ft
So we know the room is 21ft by 17.5ft
Now lets plug these two values in for the area formula above(L*W):
21ft*17.5ft:
367.5ft^2
Or
367.5 square feet.
Hope this helps!

Step-by-step explanation:
> is greater than. When you read the equation you would read x is greater than y. (The alligator always eats the larger number) < is less then.
You do not combine like-terms on opposite sides of the equality.
If f(x) = (x-6)(x +12), determine the x-intercepts of y = f(-3x).

Answer:
3/7 bags of flour
Step-by-step explanation:
Things we know:
Carmen uses 2/7 bag of flour to make 1/2 of a batch
To make 1 batch she will use :
2/7 flour/1/2 batch = x flour/1batch
2/7 = 1/2x
1/7 = x
We need 1/7 flour to make 1 batch of cookie
If 1 batch uses 1/7 of the flour then 3 batchs will need:
1/7 flour/1batch = x flour/3 batch
1/7 * 3 = x
3/7 = x
Therefore we need 3/7 flour to make 3 batches of cookies.
Solve for x
A 12.8
B 18.3
C 5.7
D 21.4
A jar contains 900 beans. Of all the beans, 7/10 are white beans and the rest are azuki beans. What is the ratio of white beans to azuki beans?
Answer:
Given that in the jar, navy beans and white beans in a ratio of 1:9. Let the amount of navy beans be x.
Then, the amount of white beans in the jar is 9x.
Given that amount of navy beans is x=90
Total amount of beans in the jar is x+9x=10x=10+90=900
So the ratio is 1:9

In right triangle ΔABC, ∠C is a right angle, AC = 20 and m∠A = 41º. Find AB to the nearest tenth.
I NEED HELP ASAP
PLEASE!!!!!!!! STEP BY STEP
Answer:
AB = 26.5º
Step-by-step explanation:
cosA = adj/hyp
cosA = AC/AB
cos41 = 20/AB
Multiply both sides by AB
AB * cos41 = 20
Divide both sides by cos41
AB = 20/cos41
AB = 26.5º
Answer:
AB = 26.5Explanation:
ΔABC is right in the angle ∠C
in this case AB is the hypotenuse of the triangle ABC
according to the given data we will use the length of AC which is the adjacent side to the angle ∠A and the Cosine of the angle ∠A in the following formula:
the hypothenuse = adjacent side / cosine of the angle
AB = 20 / cos(41°)
AB = 26.5

Nish is playing a video game where he pushes a button to stop a spinning wheel. Each time he presses the button, the theoretical probability of scoring 0 points is 1/5, the theoretical probability of scoring 10 points is 3/5, and the theoretical probability of scoring 20 points is 1/5. How many times would you expect Anish to score 10 points if he presses the button 10 times?
Answer:
6 times
Step-by-step explanation:
The theoretical probability of scoring 10 points upon pressing a button = 3 / 5
The expected number of times 10 points is scored if button is pressed 10 times :
This will be ;
(Number of times button is pressed * theoretical probability of scoring 10 when button is pressed)
(10 * 3 / 5)
= 30 / 5
= 6 times
how to change 5 to base 1
Answer:I'm going to illustrate by converting 4325 to base 8. I an going to do it in two steps. First convert 4325 to base 10 and then convert this base 10 number to base 8.
Converting 4325 to base 10 just requires remembering what base 5 means.
4325 = 4 × 52 + 3 × 5 + 2 = 4 × 25 + 15 + 2 = 117.
To put 117 into base 8 imagine you have 117 CDs. Put them is stacks of 8 disks each. You get 14 stacks of 8 disks with 5 remaining (that is 117 ÷ 8 = 14 with a remainder of 5). Now take the 14 stacks and put them in groups of 8. You get 1 group of 8 stacks and 6 stacks remaining ((that is 14 ÷ 8 = 1 with a remainder of 6). Thus you have
1 group of 8 stacks (1 × 8 × 8 disks)
6 stacks (6 × 8 disks) and
5 individual disks.
Hence 117 = 1 × 82 + 6 × 81 + 5 = 1658
Here, more compactly is what I did
117 ÷ 8 = 14, remainder of 5
14 ÷ 8 = 1, remainder 6
1 ÷ 8 = 0, remainder 1
Read the remainders from bottom to top, 1658

Step-by-step explanation:
(Don't answer if unsure) If the triangle rotated 360 degrees to the right, where would the plotted points be? (Coordinates are (-8,2) (-8,8) (-4,2)
Answer:
Step-by-step explanation:
A correct answer can only be obtained from a complete question.
A rotation is not always about the origin, but in the absence of information, this will be assumed.
Rotating to the right is assumed to mean rotated from the second towards the first quadrant about the origin.
Rotating any shape about the origin by 360° will always return to the original (starting) position, so the final coordinates will be (-8,2) (-8,8) (-4,2).
Please help me with this. I’ve been struggling.
