B) 3/2
C) 3/4
D) 4/3

Answer:

For 3 people Kevin would need 90g of strawberry jelly, 6 sponge fingers, 315ml of custard and 135g of tinned fruit.

Step-by-step explanation:

To work this out you would need to work out how many ingredients would be needed for 1 person, so you would need to divide each ingredient amounts by 4. (For example for the strawberry jelly you would do 120÷4 which is 30).

Then, to work out how many ingredients would be needed for 3 people you would need to multiply the ingredient amounts by 3. (Like 30×3 is 90).

Answer:

[tex]r=4\csc \theta \cot\theta[/tex]

Step-by-step explanation:

The given parametric equations are;

[tex]x=t^2[/tex]

[tex]y=2t[/tex]

We make t the subject in the second equation to get:

[tex]t=\frac{y}{2}[/tex]

We substitute into the first equation to get:

[tex]x=(\frac{y}{2})^2[/tex]

We use the relation:

[tex]x=r\cos \theta[/tex] and [tex]y=r\sin \theta[/tex]

[tex]r\cos \theta=(\frac{r\sin \theta}{2})^2[/tex]

[tex]r\cos \theta=\frac{r^2\sin^2 \theta}{4}[/tex]

[tex]r=4\csc \theta \cot\theta[/tex]

An equation is formed of two equal expressions. The polar form of parametric equations x=t² and y=2t is r = 4cosecθ cotθ.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The following parametric equation x=t² and y=2t in the form of a polar equation can be written as,

y=2t

t = y/2

Substituting the value of y from the second equation in the first,

x = (y/2)²

Using the basic relation we can write, the value of x and y as,

x = r cosθ

y = r sinθ

substitute the value of x and y,

r cosθ = [(r sinθ)/2]

r sinθ = (r²sin²θ)/4

r = 4cosecθ cotθ

Hence, the polar form of parametric equations x=t² and y=2t is r = 4cosecθ cotθ.

The difference between two times six and five is calculated by first multiplying two by six to get twelve, then subtracting five from twelve, resulting in seven.

The student has asked about the difference between two times six and five. To solve this, we first calculate two times six, which gives us twelve. Then, we subtract five from twelve to find the difference. Therefore, the calculation we need to make is 12 - 5 = 7.

So, the difference between two times six and five is seven.

Answer:

1505 cubic centimeters

Step-by-step explanation:

Lengths are related by scale factor "k"

Volumes are related by scale factor "k^3"

From large to small:

What multiplied by 18, gives us 6? We can write:

18(k)=6

k = 6/18 = 1/3

So scale factor is 1/3

Now in terms of volume, the larger is given as 40, 635, so we can set up:

40,635 * k^3 = smaller volume

we know k = 1/3, so

40,635 * (1/3)^3 = smaller volume

Thus, smaller volume = 40,635 * (1/3)^3 = 1505

To estimate the mouse population after 30 days using the given model, M(t)=200(1.2)^t, evaluate the expression with t=30, which results in approximately 47,475 mice.

The student is asking how many mice will be in the building after 30 days according to the exponential growth model M(t) = 200(1.2)^t, where t is the time in days and M(t) is the population of mice at time t. To find the answer, we simply plug the value of 30 days into the model to get M(30) = 200(1.2)^30.

Calculating the expression:

First, calculate 1.2 raised to the power of 30, which gives us approximately 237.3769.

Then, multiply that by the initial population of 200 mice, yielding a result of approximately 47,475.38.

Therefore, after 30 days, assuming no mice die, there will be approximately 47,475 mice in the building.

Step-by-step explanation:

The given equation is;

–m + 0.02 + 2.1m = –1.45 – 4.81m

The highest decimal places is 2.

This implies that, we must multiply each term of the equation by [tex]10^2=100[/tex] before solving in order to eliminate the decimal.

In that case the equation becomes;

–100m + 2 + 210m = –145 – 481m

a)Each egg requires 0.5 cups of sugar in Grandma's recipe.

b)The ratio of baking powder to salt is 3:1.

a) The recipe uses 2 cups of sugar and 4 eggs. To find out how many cups of sugar are needed per egg, we divide the total cups of sugar by the number of eggs:

2 cups of sugar / 4 eggs = 0.5 cups of sugar per egg

So, 0.5 cups of sugar are needed for each egg.

b) Ratio of baking powder to salt

The recipe calls for 3/4 teaspoon of baking powder and 1/4 teaspoon of salt. To find the ratio of baking powder to salt, we divide the amount of baking powder by the amount of salt:

(3/4) teaspoon of baking powder / (1/4) teaspoon of salt = 3

Thus, the ratio of baking powder to salt is 3:1. This means there is three times as much baking powder as salt in the recipe, which aligns with your sister's observation.

Answer:

ice cream = 3.80$

cup cake = 4.25$

donuts = 2.5$

Step-by-step explanation:

a=ice cream

b = cup cake

c = donuts

we can write the following equations given from the picture:

a+b+b=12.30$   equation 1

b+c+a=10.55$   equation 2

b+c+c =9.25$   equation 3

using equation 1 we have:

2b+a=12.30

a=12.30-2b

using equation 3 we have:

2c+b=9.25

c=(9.25-b)/2

using equation 2 we have:

b+((9.25-b)/2)+12.30-2b=10.55

((2b+9.25-b)/2) - 2b = 10.55-12.30

((2b+9.25-b-4b)/2) =-1.75

-3b+9.25=2*(-1.75)

-3b= -3.5-9.25

-3b=-12.75

b=12.75/3

so we have b= 4.25$ = cup cake

we have:

c=(9.25-b)/2= (9.25-4.25)/2

c=2.5$= donuts

a= 12.30-2b= 12.30-2*(4.25)

a= 12.30-8.5 = 3.8$ = ice cream

Answer:32 degrees

Step-by-step explanation:a triangle total is 180 degrees. So subtract 116 and 32 by 180 to get 32

Answer: 32°

Step-by-step explanation: Hello There! The Answer is 32°. This is because when we add up 116° and 32° we get 148° to get the Answer we subtract 148° from 180° and we get a difference of 32°.

Answer:

45°

Step-by-step explanation:

Imagine a waistband stretched around the middle of an apple, horizontally.

The waistband could be represented by the circumference of the apple, with a central angle of 360°.

Divide this central angle by 8, obtaining 45°.  Each piece of apple is measured by a central angle of 45°.

To find the angle measure of each of the 8 pieces of the apple, divide the total degrees in a circle by 8, resulting in each piece having an angle measure of 45 degrees.

To find the angle measure of each piece, we divide the circle into 8 equal slices.

Each slice corresponds to an angle of 360 degrees (the total degrees in a circle) divided by 8, which equals 45 degrees for each piece.

Therefore, the angle measure of each piece of the apple is 45 degrees.

Good luck!!

Answer:

16b^4/81

Step-by-step explanation:

Answer: 5

Step-by-step explanation: The dot in the middle of the circle is the center point of the circle. This means that it bisects every point from one edge to the other cutting through the middle. The two vertical red lines in the middle of the circle indicate they are the same measure. knowing this and that the angle interiors are 90 degrees, we can conclude that x is the same length as the 5 diagonal from it.  

Answe is 5..

The (.) is the center of the circle..

The (|) mesns these lines are equal..

The angles also are right angles and equal..

Means the length ofvthis line also equals the other line = 5

For this case we have that by definition:

[tex]Sec (a) = \frac {1} {cos (a)}[/tex]

Then, we can rewrite the expression as:

[tex]Sec (120) = \frac {1} {cos (120)}[/tex]

[tex]cos (120) = cos (180-60) = - cos (60) = - \frac {1} {2}[/tex]

So:

[tex]Sec (120) = \frac {1} {- \frac {1} {2}}\\Sec (120) = - 2[/tex]

Answer:

-2

The exact value of sec 120° is -2 as secant function is the reciprocal of the cosine function,

The secant function is the reciprocal of the cosine function, so we can find sec 120° by finding the reciprocal of cos 120°.

First, let's determine the value of cos 120°.

We know that cos 120° is negative in the unit circle, so we need to find the cosine of the reference angle, which is 60°.

In the unit circle, at 60°, the cosine value is 1/2.

Since cos 120° is negative, the value is -1/2.

Now, we can find the exact value of sec 120° by taking the reciprocal of -1/2:

sec 120° = 1 / (cos 120°) = 1 / (-1/2) = -2.

Therefore, the exact value of sec 120° is -2.
