Answer:
a) 15:7
b) 1950 ml
c) There were 10 people in the group
Step-by-step explanation:
a) In its basic form, the ratio would be 750:350. However, to get it to it's most basic form, we must find the greatest common factor (GCF) of 750 and 350, which is 50. Then, we divide both numbers by the GCF so that 750 is 15 and 350 is 7. Therefore, the basic form of the ratio is 15:7.
b) First, we can find the amount of chicken stock needed for 12 people, which is just double of the recipe since the recipe is for 6 people. (900 * 2 = 1800). Then, we need to figure out how much chicken stock is required for one person since there are 13 and not 12. We can do this by multiplying 900 by 1/6 (since it's for 1 person out of the 6 people recipe) to get 150. Then, add the amount of chicken stock needed for 12 people and 1 person together. 1800 + 150 = 1950.
c) First, we must figure out how many grams of leeks are required for just one person. We can do this by taking the amount needed in the recipe (for 6 people) and dividing it by 6 to get the amount needed for 1 person. 750 divide by 6 is 125, so 125 g of leeks are required to make soup for 1 person. Then, we take the total amount of leeks that Delia used (1250) and divide that by 125 to get 10.

The sixth column is labeled Total with entries 76, 27, 75, 122, 300. Which statement is true about whether A and B are independent events
Answers
The statement that is true about whether A and B are independent events is D. A and B are not independent events because P(A∣B) = 0.375 and P(A) = 0.25.
How to depict the events?Let A be the event that the person rides the bus to school, then:
P(A) = 75/300
P(A) = 0.25
Let B be the event that the person has 3 or more siblings, then:
P(B) = 24/300 = 0.25
P(A/B)=9/24
P(A/B)=0.375
Since P(A/B)=0.375 is different from P(A)=0.25 the events are not independent.

Step-by-step explanation:
First of all, you have to distribute the term in front of the parenthesis into the term(s) inside of it. In this case, “5-” is not a term because the “-” symbol is following it. However, we can distribute that particular symbol into the parenthesis. We then have 5+ 28 because - x - = +, and 5 x 7 - 5 = 28.

Answer:
4 pt = 8 cups
28 qt = 7 gallons
Step-by-step explanation:
We know, from your chart, that 1 p = 2 c
4 p is four times 1 p
so, to scale up 1 pint to 4 pints, we multiply by 4
to figure out what the corresponding number of cups would be, we also have to multiply that value by 4
if 1 p = 2 c
then 4 p = 8 c
(1 x 4) (2 x 4)
8 cups
--------
If we have 28 quarts, and we know that 4 quarts is 1 gallon, we can divide 28 / 4 to find how many gallons are in 28 quarts (or, how many gallons can be made of 28 quarts)
28 / 4 = 7
7 gallons

Use a net to find the surface area of the cone to the nearest square centimeter. Use 3.14 for л. The surface area of the cone is about cm². (Round to the nearest whole number as needed.) 19 cm 4 cm (The figure is not drawn to scale.)
Answers
The surface area of the cone rounded to the nearest whole number is; 289 cm².
How to determine the cone surface area?We are given the parameters:
Radius; r = 4 cm
Slant height; l = 19 cm
Let us first calculate the base area;
The base is a circle and the area formula for a circle is;
A = πr²
Thus;
A = π(4 cm)²
A = 50.24 cm²
Lateral area;
The circumference of a circle is given by the formula;
C = 2πr
C = 2(π)(4 cm)
C = 25.12 cm
This circumference is the arc length of the sector
The area of the sector is;
A = 1/2hs
where;
h is the radius of the sector.
s is its arc length
Thus;
A = ¹/₂(19 cm)(25.12 cm)
A = 238.64 cm²
The total surface area is;
SA = 50.24 cm² +238.64 cm²
S.A = 288.88 cm² ≈ 289 cm²

Answer:
289 cm²
Step-by-step explanation:
The net for the surface area of a cone is a circular sector representing the lateral area, together with a circle representing the area of the base. The arc length of the sector is equal to the circumference of the base.
__
base areaThe area of the circular base is given by the area formula for a circle:
A = πr²
For the given radius, the area is ...
A = (3.14)(4 cm)² = 50.24 cm²
lateral areaThe circumference of the circular base is ...
C = 2πr = 2(3.14)(4 cm) = 25.12 cm . . . . also the arc length of the sector
The area of the sector is ...
A = 1/2hs . . . . where h is the radius of the sector, and s is its arc length
A = (1/2)(19 cm)(25.12 cm) = 238.64 cm²
total surface areaThe total surface area is the sum of the base area and the lateral area:
SA = 50.24 cm² +238.64 cm² = 288.88 cm² ≈ 289 cm²
The surface area of the cone is about 289 cm².

The temperature, t, in degrees celsius, in a warehouse changes according to the function t(h) = 18 + 4sin(pi/12 (x = 8)).
where h is the number of hours since midnight. at what rate is the temperature changing at 9 a.m.?
Answers
Answer:
about 1.01 °C per hour
Step-by-step explanation:
We assume the intended temperature function is ...
t(h) = 18 +4·sin(π/12(h -8))
We are asked for the rate of change when h=9.
__
derivativeThe rate of change of temperature with respect to time is the derivative of t(h) with respect to h.
t'(h) = 4(π/12)cos(π/12(h -8)) = π/3·cos(π/12(h -8))
at 9 amFor h = 9 hours after midnight, the rate of change is ...
t'(9) = π/3·cos(π/12(9 -8)) = π/3·cos(π/12) ≈ (3.14159)(0.965926)/3
t'(9) ≈ 1.01152
The rate of change of temperature at 9 a.m. is about 1.01 °C/hour.
