Answer: The answer is B or some people say its 2, and others #2: 20 cups of grade juice, and 10 cups of apple juice.

Step-by-step explanation: Ok so if there are 4 cups of grape juice and 2 cups of apple juice the we need to multiply both of them by 5 because it says what does she need to make 5 TIMES or x the recipe so 4x5=20 for grape juice and 2x5=10 for apple juice so The answer is B or some people say its 2, and others #2: 20 cups of grade juice, and 10 cups of apple juice.

Step-by-step explanation:

Answer:

9.60πcm²

Step-by-step explanation:

Area of circular disk, A = πr²

Differntiate A with respect to r

dA/dr = π * (2r^(2-1)) /(2-1) + C

dA/dr = π * 2r/1

dA/dr = 2πr

dA = 2πr * dr

dA = 2πrdr

dA = maximum error ; dr= Error in measurement = 0.2 cm ; r = radius = 24cm

dA = 2π * 24 * 0.2

dA = 9.60πcm²

Required

The cost for x months

Represent this cost with y.

So:

[tex]y = Base + Monthly * x[/tex]

[tex]y = 130 + 45 * x[/tex]

Answer:

[tex]17^4[/tex]

Step-by-step explanation:

Given:

The probability of landing A is 0.70.

The probability of landing B is 0.60.

The probability of landing both is 0.50.

To find:

The probability of landing A given it lands B.

Solution:

We have,

[tex]P(A) = 0.70[/tex]

[tex]P(B) = 0.60[/tex]

[tex]P(A\cap B) = 0.50[/tex]

The probability of landing A given it lands B is

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{0.50}{0.60}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=\dfrac{5}{6}[/tex]

[tex]P\left(\dfrac{A}{B}\right)=0.8333...[/tex]

[tex]P\left(\dfrac{A}{B}\right)\approx 0.83[/tex]

Therefore, the probability of landing A given it lands B is about 0.83.

Answer:

iii. (p - 7)(p - 3)

iv.(x - 8)(x + 4)

Step-by-step explanation:

iii. p² - 10p + 21

= p² - (7 + 3)p + 21

= p² -7p -3p + 21

= p(p - 7) - 3(p - 7)

= (p - 7)(p - 3)

iv. x² - 4x - 32

= x² - (8 - 4)x - 32

= x² - 8x + 4x - 32

= x(x - 8) + 4(x - 8)

= (x - 8)(x + 4)

Answer:

the value will fall below $3000 in the 7 th year because :

Step-by-step explanation:

15% of 13500 is 2025

On subtracting 2025 from 13500 every time we can see that the value keeps dropping.

So, we will get $3375 in year 6 and in year 7 we will get $1350 by subtracting 2025 from 3375.

Hence we will get 1350 at the 7th year.

After 6.79 years, the car's value will drop below $3,000.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, The following is a representation of the exponential function to model the car's value:

V(t) = 13500 (1 - 0.15)ⁿ

V(t) = 13500(0.85)ⁿ

Here, V(t) denotes the car's worth at time n in years, and 0.85 denotes the annual depreciation rate of 15%.

Hence, The following equation can be put up to determine when the car's value will drop below $3,000:

13500(0.85)ⁿ = 3000

As we solve for n, we obtain:

n = (log(3000/13500)/log(0.85))

n = 6.79

So, after roughly 6.79 years, the car's value will drop below $3,000.

Step-by-step explanation:

Answer:

The answer is "This is the right thing. There might be a surface sample which indicates that the population is not regular".

Step-by-step explanation:

When the community is ordinary or a biosensor, a normal distribution could be calculated for the dependent variable. Data shows chi-squared distributions of n-1 degrees - of - freedom about the dependent variable.

Chi-square was its precise outcome for the data set, while chi-square is a close estimate for non-normal information. So, we should also calculate CI for uncommon information. Throughout the case of an outlier, however, data refers to non because as mean tends to move in a skewed direction to the outer surface.

Answer:

The measure of angle BED is 82°

Step-by-step explanation:

The angles of a triangle, all together, equal 180°.

Angle B and D are the same and angle B is 49° so angle D is also 49°.

You add 49 to 49 which equals 98, and subtract 98 from 180 to find out what angle E is.

Answer:

[tex]y = \frac{1}{6}x - 4[/tex]

[tex]y = \frac{x}{2} + 2[/tex]

[tex]y = \frac{1}{8}x[/tex]

[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]

[tex]y = 12x - 9[/tex]

Step-by-step explanation:

Required

Represent in gradient intercept form

This means that the equation be in form: [tex]y = mx + c[/tex]

Solving (a): [tex]3y = \frac{1}{2}x - 12[/tex]

Divide through by 3

[tex]\frac{3y}{3} = \frac{1}{3*2}x - \frac{12}{3}[/tex]

[tex]y = \frac{1}{6}x - 4[/tex]

Solving (b): [tex]5x = 10y - 20[/tex]

Make y the subject

[tex]10y = 5x + 20[/tex]

Divide through by 10

[tex]y = \frac{5x}{10} + \frac{20}{10}[/tex]

[tex]y = \frac{x}{2} + 2[/tex]

Solving (c): [tex]x = 8y[/tex]

Make y the subject

[tex]8y= x[/tex]

Divide through by 8

[tex]y = \frac{1}{8}x[/tex]

Solving (d): [tex]\frac{1}{2}x = 3y - 2[/tex]

Make y the subject

[tex]3y = \frac{1}{2}x+ 2[/tex]

Divide through by 3

[tex]y = \frac{1}{2*3}x+ \frac{2}{3}[/tex]

[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]

Solving (d): [tex]\frac{2}{3}y - 8x = -6[/tex]

Make y the subject

[tex]\frac{2}{3}y = 8x -6[/tex]

Divide through by 3/2

[tex]\frac{3}{2} * \frac{2}{3}y =\frac{3}{2} * ( 8x -6)[/tex]

[tex]y =\frac{3}{2} * ( 8x -6)[/tex]

[tex]y =\frac{3}{2} * 8x -\frac{3}{2} * 6[/tex]

math

Answer:

If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi.  Circumference = 18 pi  Area = 81 pi  Area is 4.5 times greater than the circumference. The answer is C.

Answer:

Those two quantities are incommensurate, you can't compare them. The circumference is a length and the area is an area. There is no way to compare the two.

Now if you're talking about the formula Area = circumference squared over 4 times Pi, and if you're just going to go with the numerical values of Area and circumference, then there is an answer.
