Ava put 10 spoons of sugar in 5 coffees. How many spoons of sugar does Ava put in one coffee

Answer:

  y = csc(x) -1

Step-by-step explanation:

The vertical offset of -1 is your first clue. Your second clue is that the range does not include (-2, 0), typical of cosecant and secant functions (offset by -1).

_____

Comment on answer choices

Apparently the cosine choices are intended to be confused with the cosecant choice. The cosine function has a range of [-1, 1], so will not show any vertical asymptotes anywhere, regardless of scaling or translation.

Square B Area = 144cm²

Square B = X

The dimensions of Square A are three times The dimensions of Square B

Square A = 3 * Square B

Square A = 3X

The area of Square A is 1,296 cm2.

Square A Area = (3X)² = 1296

Square B Area = X²

Solve to find X.

(3X)² = 1296

3X = 36

X = 36/3 = 12

Square B Area = 12² = 144

Square B Area = 144cm²

Final answer:

The area of Square B is 144 cm², calculated by dividing the area of Square A (1,296 cm²) by 9, because the area of a square scales with the square of its linear dimensions.

Explanation:

The area of Square A is given as 1,296 cm². Since the dimensions of Square A are three times the dimensions of Square B, we can find the area of Square B by understanding that area scales in proportion to the square of the linear dimensions. This means that if one dimension is three times another, the area will be nine times (3² = 9) larger.

To find the area of Square B, we simply divide the area of Square A by 9:

Area of Square B = Area of Square A / 9

Area of Square B = 1,296 cm² / 9

Area of Square B = 144 cm².

Therefore, the area of Square B is 144 cm².

Lets say the number is ab. Its value is 10a + b  

When it is reversed it is 10b + a = 12a+1.2b (from the condition its value should increase 0.2 times).  

11 a = 8.8b  

a/b = 8.8/11 = 0.8/1 = 8/10 = 4/5 ( we do this because a and b should be natural numbers less than 10).  

answer is 45.

A two-digit number less than 100 that increases by one-fifth of its original value, when its digits are reversed, can be found by setting up an equation. By defining the tens digit as 'a' and the unit digit as 'b', the equation 6a = 9b is derived. Solving for the digits within their possible values, the number 12 is found.

To find a number less than 100 that increases by one-fifth of its value when its digits are reversed, we need to set up an equation. Let's call the tens digit a and the units digit b. The number can be written as 10a + b. When the digits are reversed, the number becomes 10b + a. The problem states that reversing the digits increases the number by one-fifth of its original value, which gives us the equation:

(10a + b) + \frac{1}{5}(10a + b) = 10b + a

Now solving the equation:

6a = 9b

As a and b are digits, their possible values range between 0 and 9. We find that a = 1 and b = 2 satisfy the equation. Hence, the number is:12

When we reverse the digits, we get 21, which is greater than 12 by \frac{1}{5} of 12, as required.

The distance is 10 units.

EXPLANATION

Let us use the distance formula to find the distance between,

[tex](x_1,y_1)=(1,4)[/tex]

Answer:

Step-by-step explanation:

The triangle is recognizable as a 30°-60°-90° right triangle, which has side length ratios ...

  1 : √3 : 2

Side x is thus twice the length of short side 4, so x = 8.

Side y is √3 times the length of short side x-6 = 2, so y = 2√3.

_____

If you don't happen to recognize the triangle dimensions, you can find x and y using the Pythagorean theorem.

  x = √(4² +(4√3)²) = √64 = 8

  y = √(4² -2²) = √12 = 2√3

Answer:

1.33

Step-by-step explanation:

Solve for r in the first equation:

3(r+300) = 6

Use the distributive property:

3r + 900 = 6

Subtract 900 from both sides:

3r = -894

Divide both sides by 3:

r = -894 / 3

r = -298

Now you have r, replace r in the second equation and solve:

r +300 -2 =

-298 + 300 - 2 = 0

The answer is 0.

Answer:

0 is the value of r+300-2

Solve for r in the first equation:

3(r+300) = 6

Use the distributive property:

3r + 900 = 6

Subtract 900 from both sides:

3r = -894

Divide both sides by 3:

r = -894 / 3

r = -298

Now you have r, replace r in the second equation and solve:

r +300 -2 =

-298 + 300 - 2 = 0

The answer is 0.

Set [tex]f(x)=2x^3-3x^2+2[/tex]. Find the tangent line [tex]\ell_1(x)[/tex] to [tex]f(x)[/tex] at the point when [tex]x=x_1[/tex]:

[tex]f'(x)=6x^2-6x\implies f'(x_1)=12[/tex] (slope of [tex]\ell_1[/tex])

Answer:

[tex]7;41[/tex]

Step-by-step explanation:

Let

x----> the time it take Ebru to walk to the school

we know that

[tex]x=2(13)=26\ min[/tex]

so

[tex]7;15 +26\ min=7;41[/tex]

Ebru takes 26 minutes to walk to school, twice as long as biking. Leaving at 7:15 AM means she would arrive at school by walking at 7:41 AM.

If Ebru bikes to school, it takes her 13 minutes. Walking takes her twice as long, which would be 26 minutes. If Ebru leaves her house at 7:15 AM, we can calculate the time she will get to school by walking by adding 26 minutes to the departure time.

Therefore, if Ebru walks to school, she will arrive at 7:41 AM.

Answer:

8a - 48

Step-by-step explanation:

An equivalent expression is an expression which is equal to 8(a-6). You can expand or simplify an expression to make an equivalent expression. Apply the distributive property to form a new equivalent expression by multiplying 8 into each term. 8(a-6) = 8*a - 8*6 = 8a - 48. The options listed below do not connect to this problem since they do not use the same variable as the expression.

Answer:

[tex]0.5\frac{lb}{person}[/tex]

Step-by-step explanation:

we know that

To find out how many pounds of fries each person will receive, divide the total pounds of fries by the total number of people.

so

[tex]\frac{2}{4} \frac{lb}{persons}=0.5\frac{lb}{person}[/tex]

Each person will receive 0.5lb of fries.

To solve this problem, we need to divide the total weight of the French fries by the number of people sharing them. Carmen has prepared a 2lb bag of French fries for 4 people. To find out how much each person will get, we divide the total weight of the fries by the number of people:

[tex]\[ \text{Fries per person} = \frac{\text{Total weight of fries}}{\text{Number of people}} \][/tex]

[tex]\[ \text{Fries per person} = \frac{2 \text{lb}}{4} \] \[ \text{Fries per person} = 0.5 \text{lb} \][/tex]

So, each person will receive 0.5lb of fries.

Step-by-step explanation:

The equation is y = a(b(x-c))+d

So for it to move right three units, it would be x - 3.

For it to move up 4 unites, it would be x+4.

So the equation would be y = (x - 3)^2 + 4

Answer:

Final answer is approx x=1.27.

Step-by-step explanation:

Given equation is [tex]8^{-x+7}=3^{7x+2}[/tex].

Now we need to solve equation [tex]8^{-x+7}=3^{7x+2}[/tex] and round to the nearest hundredth.

[tex]8^{-x+7}=3^{7x+2}[/tex]

[tex]\log(8^{-x+7})=\log(3^{7x+2})[/tex]

[tex]\left(-x+7\right)\cdot\log\left(8\right)=\left(7x+2\right)\cdot\log\left(3\right)[/tex]

[tex]-x\cdot\log\left(8\right)+7\cdot\log\left(8\right)=7x\cdot\log\left(3\right)+2\cdot\log\left(3\right)[/tex]

[tex]-x\cdot\log\left(8\right)-7x\cdot\log\left(3\right)=2\cdot\log\left(3\right)-7\cdot\log\left(8\right)[/tex]

[tex]x\left(-\log\left(8\right)-7\cdot\log\left(3\right)\right)=\left(2\cdot\log\left(3\right)-7\cdot\log\left(8\right)\right)[/tex]

[tex]x=\frac{\left(2\cdot\log\left(3\right)-7\cdot\log\left(8\right)\right)}{\left(-\log\left(8\right)-7\cdot\log\left(3\right)\right)}[/tex]

Now use calculator to calculate log values, we get:

[tex]x=1.26501646392[/tex]

Round to the nearest hundredth.

Hence final answer is approx x=1.27.
