When I am 6 my brother is half my age. How old will my brother be when I am 70?

Answers

Answer:

67

Step-by-step explanation:

Your brother is three years younger than you, so when you're 70, he'll be three years younger, 67.

~theLocoCoco

Answer:

35 years old

Step-by-step explanation:

Since your brother is half your age, that means it should be exact. 70 is not a number than would have an even split, so you would have to have either an odd number such as 5. 40 plus 40 is 80, which is to high. 30 plus 30 is 60, too low. 35 plus 35 is 70 exact. Hope this helped! Also, I dont know if this was trick question, either way, he should be half. So if you were 10, he would be 5. If you were 18, he would be 9.

calculate the angles of a triangle if the angle alpha is 16 ° greater than the angle beta and the angle gamma is 52 ° smaller than the beta GIVING BRANLIEST***​

Answers

Answer:

88°, 72°, 20°

Step-by-step explanation:

Angle alpha is 16° greater than the angle beta:

α = β + 16°

Angle gamma is 52° smaller than the beta:

γ = β - 52

Sum of angles is 180°, substitute α and β:

α + β + γ = 180°β + 16° + β + β - 52° = 180°3β - 36° = 180°3β = 216°β = 216°/3β = 72°

Then

α = 72° + 16° = 88°γ = 72° - 52° = 20°

Factor the expression.

A. ++

Answers

Answer:

(x+4) * (x+3)

Step-by-step explanation:

To factor the general expression:

X²+ax+c

We need to find the numbers b and d of the factoring expression:

(x+b) * (x+d)

Where:

b*d = c

b+d = a

For the expression:

X²+7x+12

We need to find b and d that:

b+d = 7

b*d = 12

If b = 4 and d = 3, the expression could be:

(x+4) * (x+3) = X² + 4x + 3x + 12 = X² + 7x +12

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

3y = -2x

y = x - 5

Step 2: Solve for x

Substitution

Substitute in y:                    3(x - 5) = -2xDistribute 3:                         3x - 15 = -2xAdd 2x on both sides:        5x - 15 = 0Add 15 on both sides:         5x = 15Divide 5 on both sides:       x = 3

Step 3: Solve for y

Define equation:                    y = x - 5Substitute in x:                       y = 3 - 5Subtract:                                 y = -2

Answer:

y = -2

x = 3

Step-by-step explanation:

First plug in the y= x-5 equation into the 3y = -2x so that it looks like this:

3(x-5)=-2x

Second after distributing the 3 to the x and -5 you will have an equation that looks like this: 3x -15 = -2x

Then you have keep the x's on one side so you add 2x to both sides and add 15 as well so now you have: 5x = 15

Divide both sides by 5 and get x = 3

To find y, you plug x=3 in in to the y = x-5 and get that y = -2

B. f(n)=−12(4)n−1
C. f(n)=−12(4)n
D. f(n)=12(−4)n−1

Answers

Answer:

An explicit representation for the nth term of the sequence:

[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]

It means, option (B) should be true.

Step-by-step explanation:

Given the geometric sequence

[tex]-\frac{1}{2},\:-2,\:-8,\:-32,...[/tex]

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

[tex]f_n=f_1\cdot r^{n-1}[/tex]

Determining the common ratios of all the adjacent terms

[tex]\frac{-2}{-\frac{1}{2}}=4,\:\quad \frac{-8}{-2}=4,\:\quad \frac{-32}{-8}=4[/tex]

As the ratio is the same, so

r = 4

Given that f₁ = -1/2

substituting r = 4, and f₁ = -1/2 in the nth term

[tex]f_n=f_1\cdot r^{n-1}[/tex]

[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]

Thus, an explicit representation for the nth term of the sequence:

[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]

It means, option (B) should be true.

Therefore, Harold used the point (7, 0)

Step-by-step explanation:

Answer:

The linear equation in point-slope form is

y-10 = 3(x-5)

Step-by-step explanation:

Given

slope = m = 3point (5, 10)

We know that the point-slope form of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope and (x₁, y₁) is the point

substituting the values m = 3 and the point (5, 10)

y-10 = 3(x-5)

Thus, the linear equation in point-slope form is

y-10 = 3(x-5)

If she wants to make at least $100.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Heather needs to sell? Input your answer as a whole number.

Answers

Answer:

around 66.66

Step-by-step explanation:

hope this helps

Answer:

70 cups

Step-by-step explanation:

C. P. of lemonade supplies = $5.25

S. P. of one cup of lemonade = $1.50

Let us assume that she should sell n cups of lemonade to make a profit of $100.00.

Therefore, S. P of n cups = $1.50n

Since,

Profit = S. P. - C. P.

Therefore,

100 = 1.5n - 5.25

100 + 5.25 = 1.5n

105.25 = 1.5n

n = 105.25/1.5

n = 70.1666667

n = 70 cups
