Answer:

4 CUPS OF SUNFLOWER SEEDS for the larger batch

Step-by-step explanation:

From the small batch:

2 cups of peanuts= 1 cup of sunflower seeds

Since the ratios are thesame, it therefore means that the proportion will be thesame.

For the large batch:

8 cups of peanuts = X cups of sunflower seeds.

Mathematically, let's express it as:

Let p = cups of peanuts

S= cups of sunflower seeds

X = unknown number of sunflower seeds

Therefore, connecting equation is:

2P = 1S

8P = X's

Cross Multiply to solve for X

X's * 2P = 1S * 8P

2PX = 8P

X = 8P / 2P

It therefore means that there'll be a need of:

4 CUPS OF SUNFLOWER SEEDS for the larger batch

A car uses 3t gallons of gasoline to travel 5 miles.
Nadusha1986 [10]

Answer: a) \frac{24}{5}t gallons are needed to travel 8 miles

b) Town X and town Y are 15 miles apart.

Step-by-step explanation:

Given : Gasoline used to travel 5 miles = 3t gallons

a) To find: Gasoline used to travel 8 miles = ?

Using unitary method:

If Gasoline used to travel 5 miles = 3t gallons

Thus Gasoline used to travel 8 miles = \frac{3t}{5}\times 8=\frac{24}{5}t gallons

\frac{24}{5}t gallons are needed to travel 8 miles

b) when 3t gallons of gasoline are used , distance covered = 5 miles

Thus when 9t gallons of gasoline are used , distance covered = \frac{5}{3t}\times 9t=15 miles

Thus town X and town Y are 15 miles apart.

x = 1 mile · 0.03429 = 0.03492 miles
1 mile = 5,280 feet
0.03492 · 5,280 = 184.38 ft

The temperature of a freezer started at 18ºC. After cooling for a few hours, the freezer had a temperature of –12ºC. What is the
Zarrin [17]

Answer:

a.–12 – 18

Step-by-step explanation:

We have to compute the difference (the subtraction) between the new, colder temperature, which is equal to -12 °C, and the original temperature, which is equal to 18 °C, that is:

colder temperature - original temperature

Replacing with data:

-12 °C - 18 °C = -30 °C

storchak [24]

Answer with Step-by-step explanation:

We have to prove that

sin 2\theta=2sin\theta cos\theta by using Euler's formula

Euler's formula :e^{i\theta}=cos\theta+isin\theta

e^{i(2\theta)}=(e^{i\theta})^2

By using Euler's identity, we get

cos2\theta+isin2\theta=(cos\theta+isin\theta)^2

cos2\theta+isin2\theta=(cos^2\theta-sin^2\theta+2isin\theta cos\theta)

(a+b)^2=a^2+b^2+2ab, i^2=-1

cos2\theta+isin2\theta=cos2\theta+i(2sin\theta cos\theta)

cos2\theta=cos^2\theta-sin^2\theta

Comparing imaginary part on both sides

Then, we get

sin2\theta=2sin\theta cos\theta

Hence, proved.
