Step-by-step explanation:
First find the area of each individual shape.
3 x 4 = 12 / 2 = 6 for the triangle on the left
5 x 4 = 20 for the rectangle
2 x 4 = 8 / 2 = 4 for the right triangle
Now all yo udo is add them all up to get the total area

Step-by-step explanation: alright so is it is 4.5 you just divide 1/4 by 4.5 (
18) 18 x 12 = 216 miles :3
Answer:
Step-by-step explanation:
1/4 inch=12 miles Harrisburg and Leighton= 4.5 inches
1) Set up a proportion: ¼ /12 miles = 4.5 inches/ x miles
(inches across from inches
miles across from miles )
2) Use cross-products to solve: ¼x= 12(4.5)
¼x/¼ = 54/ ¼
x=216miles
The distance between Harrisburg and Leighton is 216miles
"what is the value of a in the equation 81^b=a^4b"
Answers
Answer:
Step-by-step explanation:
The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ [tex]81^b = a^4^b[/tex]
Now,
Solve the expression for the value of b as;
⇒ [tex]81^b = a^4^b[/tex]
Since, 81 = 3⁴
So, We get;
⇒ [tex]3^4^b = a^4^b[/tex]
By comparing, we get;
⇒ a = 3
Thus, The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.

On Monday, 344 students went on a trip to the zoo. All 6
buses were filled and 8 students had to travel in cars. How many students were
in each bus ?
Answers
Answer:
56 students were in each bus is our answer
Step-by-step explanation:
This is true because if 8 students went in cars then we have to subtract 8 from 344, so we get 336 then from there we divide 6 from 336 giving us 56, thus 56 is our answer.
Your Welcome, Have A Splendid Day, And Hope This Helps!!!
if you subtract the 8 students from the total number you get 336
336 students divided by 6 busses equals 56 students in each bus

a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth
Answers
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
V = 603.19 cm3, A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

Find x. Then find the measure of angles A, B and C.
Answers
Answer:
x= 11
A=59
B= 37
C = 84
Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.
[tex]6x + 3x + 9x+4-15-7 = 180\\18x-18=180[/tex]
Then inverse operation,
[tex]18x-18=180\\18x=198\\x=11[/tex]
After to get a, b, and c you just need to plug in x.
[tex]6(11)-7=a\\3(11)+4 = b\\9(11)-15=c[/tex]

Answer:
Step-by-step explanation:
Volume =
4 × π × r³ / 3 <----- This is our volume equation
= 4 × π × 1.9³ / 3 (Substituted the unknown r for the radius given, 1.9 cm)
= 4 × π × 6.859 / 3 (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9
= 4 × 21.548184011 / 3 (Multiplied 6.859 by pi "π")
= 86.1927360439 / 3 (Multiplied that by 4)
= 28.7309120146 cm³ (Divided it by 3, gave it a ³ dimension because it is 3D, volume.

Answers
Q=4
15q-16=8q+12
7q-16=12
7q=28
Q=4
Now your equation is 15q - 16 = 8q + 12
Step 2: Subtract 8q from both sides
Now your equation is 7q - 16 = 12
Step 3: Add 16 to both sides
Now the equation is 7q = 28
Step 4: Divid each side by 7
