Answer:
7/12 teaspoons
fraction
Step-by-step explanation:
Amount of salt that would be used = 1 x
Convert to an improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
(1 x 4) + 3 =
7/4 x 1/3 = 7/12
The given is a triangle and we can solve the problem using the equation shown below:
Area = 1/2*base*heigth
Where base = 2.9 cm
Height = 9 cm
Solving for the area, we have:
Area = 1/2*2.9*9
Area = 13.05 cm²
Answer:
p=0.3446
Step-by-step explanation:
-Let Y be the random variable with parameter .
-The probability mass function is given as:
We set T=10, and calculate the probability as
Hence, the probability that 10 squared centimeters of dust contains more than 10040 particles is 0.3446
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.
Answer:
∠8 = 40°, ∠6 = 50°, ∠9= 140°
Step-by-step explanation:
∠8 = 40° (vertically opposite angles are congruent)
now, using angle sum property of triangles
∠6 + 90° + 40° = 180°
∠6 = 180° - 130°
∠6 = 50°
and, using exterior angle property,
50° + 90° = ∠9 = 140°
