if i have 67 apples and eat 34 and times it by 12 how much do i have?

Answer:

Step-by-step explanation:

let x be the number

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

2x+16=-4x+4

6x=-12

x=-2

Answer:

x=-2

Step-by-step explanation:

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

2x+16=-4x+4

6x=-12

x=-2

X = -2500

This is because:

For this case we must find the value of the variable "x" of the following expression:

[tex]\sqrt {-4x} = 100[/tex]

Now, we square both sides of the equation:

[tex]-4x = 100 ^ 2\\-4x = 10000[/tex]

We divide between -4 on both sides of the equation:

[tex]x = \frac {10000} {- 4}\\x = -2500[/tex]

ANswer:

[tex]x = -2500[/tex]

Answer:

[tex]\frac{10}{x} \ miles[/tex]

Step-by-step explanation:

Givens

So, how far does he walk in one hour?

Basically, the question is asking the constant rate of change of the person's position. In other words, it's asking about the man's velocity: how many miles per hour.

The expression that represents this situation is

[tex]\frac{10}{x} \ miles[/tex]

Because, the problem refers to the ratio of change, which is the quotient between the distance traveled and the time that took to travel that distance.

Answer:

(x -5) * (x -2) = x^2 -7 +10

Step-by-step explanation:

Answer:

Equation: a - 16 = 3

Answer: a = 19

For sin, cos, and tan, let's use an abbreviation.

SOH-CAH-TOA

[tex]sin=\frac{opposite}{hypotenuse}[/tex]

[tex]cos=\frac{adjacent}{hypotenuse}[/tex]

[tex]tan=\frac{opposite}{adjacent}[/tex]

But before that, we should solve for the missing side.

Since this triangle is a right triangle, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2 \\ \\ 6^2+8^2=c^2 \\ \\ c^2=36+64 \\ \\ c^2=100 \\ \\ c=10[/tex]

So the hypotenuse is 10.

Let's plug in.

sin θ = 6/10 --> 3/5

cos θ = 8/10 --> 4/5

tan θ = 6/8 --> 3/4

Now for the cosectant, secant, and cotangent, we'll just use the definitions.

Cosectant is hypotenuse over opposite.

Secant is hypotenuse over adjacent.

Cotangent is adjacent over opposite.

So they are basically the inverses.

csc θ = 10/6 --> 5/3

sec θ = 10/8 --> 5/4

cot θ = 8/6 --> 4/3

Answer:

8 appetizer recipes.

Step-by-step explanation:

Given,

The number of appetizer recipes Laverne already knew = 2,

Also, she learns 3 new appetizer recipes during each week of school.

So, the additional number of recipes she learn in 2 weeks = 2 × 3 = 6,

Hence, the total  appetizer recipes she would know = The recipes she already knew + the additional number recipe she learnt in 2 weeks

= 2 + 6

= 8

Answer:

[tex]V=430.19\ cm^3[/tex]  or  [tex]V=136.93\pi\ cm^3[/tex]

Step-by-step explanation:

The surface area of a sphere is:

[tex]A_s=4\pi r^2[/tex]

Where r is the radius of the sphere

In this case we know that [tex]A_s = 275.561\ cm^2[/tex]

So

[tex]4\pi r^2=275.561[/tex]

We solve the equation for r

[tex]4\pi r^2=275.561\\r^2 = \frac{275.561}{4\pi}\\\\r=\sqrt{ \frac{275.561}{4\pi}}\\\\r=4.683\ cm[/tex]

Now we know the radius of the sphere.

The volume of a sphere is:

[tex]V=\frac{4}{3}\pi r^3[/tex]

We substitute the value of the radius in the formula

[tex]V=\frac{4}{3}\pi (4.683)^3[/tex]

[tex]V=430.19\ cm^3[/tex]

Answer:

The answer is B.

Answer:

D, neither

Step-by-step explanation:

to determine whether a function is even, odd or neither, we need to know what it means

an even function is symmetric with respect to the y-axis

an odd function is symmetric with respect to the origin

to solve an equation to see if its even or odd, we would need to substitute x in the equation for -x.

in an even function when we substitute f(-x), it should be equal to to f(x)

in an odd function when we substitute f(-x), it should be equal to -f(x)

so lets test the function given to see if its even

f(x) = x³ + 4x

f(-x) = (-x)³ + 4(-x)

f(-x) = x³ - 4x

f(-x) = x³ - 4x ≠ f(x) = x³ + 4x

comparing this to the orignal function, we see that f(-x) = x³ - 4x is not even as we did not get the same output as the original function

now we should test to see if its odd. we have already seen what f(-x) is, now lets try -f(x) and compare it to f(-x) and f(x)

-f(x) = -(x³ + 4x) -->

-f(x) = -x³ - 4x ≠ f(-x) = x³ - 4x

f(-x) = x³ - 4x ≠ f(x) = x³ + 4x

comparing this to f(x) and f(-x), we see that it not odd as we did not get the same output

so the answer is D, neither even nor odd

Answer:

Step-by-step explanation:

The question is on finding the principal value

Formulae for simple interest

S.I= P×R/100×T where P is the invested amount of money, R is interest rate and T is time in years

Given that;

Simple interest=$77 , R=7% and T=1.5 years then

S.I= P×R/100×T...................substituting the values given

77=P×7/100 × 1.5

77=P×0.105

77/0.105 =P

A.

[tex]2xy^2(10x+3)[/tex]

B.

[tex](x+5)^2[/tex]

C.

[tex](x-6)(x+6)[/tex]

Step-by-step explanation:

Part A. The expression [tex]2x^2y^2+6xy^2+18x^2y^2[/tex] consists of three terms: [tex]2x^2y^2,\ \ 6xy^2,\ \ 18x^2y^2[/tex] The first and the last terms are like terms, we can add them:

[tex]2x^2y^2+18x^2y^2=20x^2y^2[/tex]

Now,

[tex]20x^2y^2=2xy^2\cdot 10x\\ \\6xy^2=2xy^2\cdot 3[/tex]

So,

[tex]2x^2y^2+6xy^2+18x^2y^2=2xy^2(10x+3)[/tex]

Part B. The expression [tex]x^2+10x+25[/tex] is a square of [tex]x+5,[/tex] so

[tex]x^2+10x+25=(x+5)^2[/tex]

Part C. Use the difference of squares formula:

[tex]x^2-36=x^2-6^2=(x-6)(x+6)[/tex]

It is pretty easy.

[tex]20 = x \times 0.08 \\ x = 20 \div 0.08 = 250[/tex]

[tex]30 = x \times 0.75 \\ x = 30 \div 0.75 = 40[/tex]

[tex]45 = x \times 0.20 \\ x = 45 \div 0.20 = 225[/tex]

[tex]36 = x \times 1.50 \\ x = 36 \div 1.5 = 24[/tex]

[tex]A=P(e)^{rt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

[tex]t=7\ years\\ P=\$1,120\\ r=0.15[/tex]  

substitute in the formula above  

[tex]A=\$1,120(e)^{0.15*7}=\$3,200.57[/tex]  

Answer:3,200.57

Step-by-step explanation:

Answer:

[tex]x=-15[/tex]

Step-by-step explanation:

[tex]8x+10-2x=4(x-5) \\ \\ 6x+10=4x-20 \\ \\ 2x=-30 \\ \\ x=-15[/tex]

x = -15

First, distribute the 4 to the x - 5 to get 8x + 10 - 2x = 4x - 20.

Now, subtract 4x and 10 from each side to get 4x - 2x = -30

Simplify the subtraction to get 2x = -30.

Divide both sides by 2 to get a final answer of x = -15.

Answer:

21.9%

Step-by-step explanation:

This involves binomial probability.

n = # of tries:  8

x = # of successes (heads):  3

Use your calculator's probability distribution function binompdf.

Type in binompdf(n, p, x), which in this case would be:

             bionompdf(8, 0.5, 3) = 0.219, or 21.9% (Answer C)

The probability of flipping a coin 8 times and getting heads 3 times is 21.9%. Therefore, option C is correct

To find the probability of flipping a coin 8 times and getting heads 3 times, we need to use the binomial probability formula. The formula is P(x) = (nCx) * p^x * (1-p)^(n-x), where n is the number of trials, x is the number of successful outcomes, p is the probability of success on a single trial, and nCx is the combination notation.

In this case, n = 8, x = 3, and p = 0.5 (since the probability of getting heads on a fair coin is 0.5). Plugging these values into the formula, we get:

P(3) = (8C3) * 0.5^3 * 0.5^(8-3)

= (8!/3!(8-3)!) * 0.5^3 * 0.5^5

= 56 * 0.5^3 * 0.5^5

= 56 * 0.125 * 0.03125

= 0.21875

= 21.9%

Answer:

Point (1 , 0.75) lies on the graph of the function ⇒ last answer

Step-by-step explanation:

* Lets revise the exponential function

- An exponential function with base b is defined by f (x) = ab^x  

 where a ≠0, b > 0 , b ≠1, and x is any real number.

- The base, b, is constant and the exponent, x, is a variable.

- The graph of it in the attached figure

- Features (for this graph):

• The domain is all Real numbers.

• The range is all positive real numbers (not zero).

• The y-intercept at (0 , 1.5). Remember any number to

  the power of zero is 1.  

• Because 0 < b < 1, the graph decreases (b = 1/2)

* Now lets check which point lies on the graph

- Substitute the value of x of the point, in the function

- If the answer is the same as y, then the point lies on the graph of

 the function

∵ y = 1.5(1/2)^x

∵ x = -3

∴ y = 1.5(1/2)^(-3) = 187.5 ≠ 1

∴ Point (-3 , 1) does not lie on the graph of the function

∵ x = 2

∴ y = 1.5(1/2)² = 3/8 ≠ 5

∴ Point (2 , 5) does not lie on the graph of the function

∵ x = -2

∴ y = 1.5(1/2)^-2 = 6 ≠ 3

∴ Point (-2 , 3) does not lie on the graph of the function

∵ x = 1

∴ y = 1.5(1/2)^1 = 0.75

∴ Point (1 , 0.75) lies on the graph of the function

Answer:

[tex]\sin\left(-180^o+\theta\right)=-\sin\left(\theta\right)[/tex]

Step-by-step explanation:

We need to find the value of [tex]\sin(-180^o+ \theta)[/tex]

So let's apply formula

[tex]\sin\left(A+B\right)=\sin\left(A\right)\cos\left(B\right)+\sin\left(B\right)\cos\left(A\right)[/tex]

[tex]\sin\left(-180^o+\theta\right)=\sin\left(-180^o\right)\cos\left(\theta\right)+\sin\left(\theta\right)\cos\left(-180^o\right)[/tex]

[tex]\sin\left(-180^o+\theta\right)=0\cdot\cos\left(\theta\right)+\sin\left(\theta\right)\cdot\left(-1\right)[/tex]

[tex]\sin\left(-180^o+\theta\right)=0-\sin\left(\theta\right)[/tex]
