Kai has been saving up money to buy a new backpack that is originally priced at $88.95. The store is having a 40% off end-of-season sale but Kai has only $55 saved up so far. Do you think he can buy the backpack? (Don't worry about sales tax in this problem.)
yes or no?

Answer: 7.5miles

Step-by-step explanation:

Since the fare is calculated as a base charge of $3.00 plus an additional $2.00 per mile traveled and also customary to leave a $2 tip and Max wants to spend exactly $20. This information can be formed into an equation as:

Let the miles that he can travel be m.

3 + (2 × m) + 2 = 20

3 + 2m + 2 = 20

5 + 2m = 20

2m = 20 - 5

2m = 15

m = 15/2

m = 7.5miles

Therefore, Max can travel 7.5miles

Respuesta:

A = 51,167

b = 28,5 pies

c = 45,4 pies

Explicación paso a paso:

C = 90 °

B = 38 ° 50 '

Convertir B a grado

1 ° = 60 '

x ° = 50 '

Multiplicar en cruz:

60x = 50

x = 50/60

x = 0,83333 °

Por lo tanto, 38 ° 50 '= 38 ° + 0.833 ° = 38.833 °

Recordar :

A + B + C = 180 ° (Suma de ángulos en un triángulo)

A + 38.833 + 90 = 180

A + 128.833 = 180

A = 180 - 128,833

A = 51,167 °

Usando identidades trigonométricas, podríamos encontrar byc

Para obtener b:

Tan B = opuesto / adyacente = b / 35.4

Tan 38,833 = b / 35,4

b = Tan 38,833 * 35,4

b = 28,5 pies

Para obtener c:

Podríamos usar:

Sin A = opuesto / hipoteno = 35,4 / c

Sin 51,167 = 35,4 / c

c * sin 51,167 = 35,4

c = 35,4 / sen 51,167

c = 45,4 pies

Answer: factors of 10 are 1, 2, 5, and 10.

Step-by-step explanation: You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.

Answer:

[tex]A=65 inches^2[/tex]

Step-by-step explanation:

From the question we are told that:

Length of wiper [tex]x=18[/tex]

Length of blade [tex]y=12[/tex]

Angle[tex]\theta=130\textdegree[/tex]

Generally the equation for Cover Area windshield wiper A_w  is mathematically given by

 [tex]A_w=x^2*\frac{\theta}{360}[/tex]

 [tex]A_w=18^2*\frac{130}{360}[/tex]

 [tex]A_w=117 \textdegree[/tex]

Generally the equation for Cover Area windshield blade A_b  is mathematically given by

 [tex]A_b=y^2*\frac{\theta}{360}[/tex]

 [tex]A_b=12^2*\frac{130}{360}[/tex]

 [tex]A_b=52 \textdegree[/tex]

Therefore total Area wiped by windshield wiper A

 [tex]A=A_w-A_b[/tex]

 [tex]A=65 inches^2[/tex]

$775 at 6% simple interest for 3 years.

Substituting the given values in the formula, We get,

[tex] \sf: \implies \dfrac{775 \times 6 \times 3}{100} [/tex]

Calculating further, We get,

[tex] \sf: \implies \dfrac{13950}{100} [/tex]

Dividing, We get,

[tex] \sf: \implies \$ 139.50[/tex]

∴ The Simple Interest is $139.50

He answered 16 questions correctly, and got 3 wrong answers.

==========================================================

Explanation:

Let

x,y,z are nonnegative whole numbers.

-------------------

Since there are 20 questions total, this means the first equation to set up is:

x+y+z = 20

Solving for y leads to

x+y+z = 20

y+z = 20-x

y = 20-x-z

We'll use this later.

-------------------

Another equation to set up is 7x-4y = 100 because Eric earns 7 points per correct answer and loses 4 points for each incorrect answer, and all that leads to 100 points total which was his quiz score. We'll ignore the questions he left blank since they add 0 points.

Let's plug the equation in which we isolated y

7x-4y = 100  

7x-4(20-x-z) = 100

7x-80+4x+4z = 100

7x+4x+4z = 100+80

11x+4z = 180

-------------------

Now we can guess and check to see which pair of x and z values will make that last equation above true. I suggest starting with the smallest possible value of x and using that x value to solve for z.

If x = 0, then,

11x+4z = 180

11(0)+4z = 180

4z = 180

z = 180/4

z = 45

So if Eric got 0 correct answers, then he left 45 questions blank. But that isn't possible because there are only 20 questions total. So we'll ignore the case that x = 0.

If we increase x by 4, and decrease z by 11, then we get another ordered pair solution to this equation

So another solution is (x,z) = (4,34)

Note that

11x+4y = 180

11(4) + 4(34) = 180

But like before, z = 34 isn't possible since 20 is the max.

Increase x by 4 again, and drop z by 11 to get (x,z) = (8,23). Again we run into the same issue as before.

Increase x by 4 again, and decrease z by 11 to get (x,z) = (12, 12). Now we have both x and z smaller than 20, but note how x+z = 12+12 = 24 which exceeds the total number of questions. So we rule this case out as well.

Do another round of "increase x by 4, decrease z by 11" to get to (x,z) = (16, 1). This is the only case left because anything beyond this, z will be negative.

Luckily, this final case does work. If Eric answers x = 16 questions correctly, then he left z = 1 of them blank. That must mean y = 20-x-z = 20-16-1 = 3 questions were incorrect.

We can see that:

7x-4y = 7(16)-4(3) = 112-12= 100

meaning that (x,y) = (16,3) is a solution to 7x-4y = 100.

-------------------

To summarize, we found that the only possible solution is (x,y,z) = (16, 3, 1)

Meaning x = 16 questions were correct, y = 3 were wrong, and z = 1 question was left blank.

Answer:

21 ounces of juice.

63 ounces of water

Step-by-step explanation:

let :

x = ounces of strawberry juice to make the strawberry infused water.

3x = ounces of water needed to make the strawberry infused water.

3x + x = 84

4x = 84

divide both sides of the equation by 4

x = 21 ounces

3x = 3 x 21 = 63 ounces

Answer:

A: FG = ½GC

Step-by-step explanation:

Since AD, BC and CD are medians concurrent at G, it means G is the centroid.

Now, when median passes through the centroid, the centroid divides the median in the ratio of 2:1.

Also,that the median touches the side of the triangle at their midpoints.

Thus,by inspection, we can say that;

GD = ⅓AD

GC/FG = 2/1

Thus, GC = 2FG and FG = ½GC

BG = ⅔BE

Tbus,looking at the options given and what we have gotten in proof, we can say only FG = ½GC is correct.

Answer:

Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, ...

Multiples of 6 are: 6, 12, 18, 24, 30, 36, ...

Step-by-step explanation:

If two numbers have no common factors greater than 1, then their LCM will be their product. For example, take numbers 7 and 9. They have none common factor greater than 1. So, LCM will be 7 * 9 = 63.

The equation y=2x+3 matches the total height of a 3-inch tree after it grows 2 inches per month.

We have given, y=2x+3

We have to determine whether the equation matches y=2x+3.

The slope-intercept form of the line is y=mx+c.

Where m is the slope

C=y-intercept

Therefore option c is correct.

because the height is three inches and the tree after it grows 2 inches per month.

The slope of a line is a measure of its steepness.

Here the slope is 2 and the y-intercept is 3.

Therefore option c is correct.

Answer:

3

Step-by-step explanation:

We know that the slope of a line passing through the points ( x ₁ , y₁) and ( x₂ , y₂ ) is ,

→ Slope ( m ) = ( y₂ - y₁) / ( x₂ - x ₁ )

→ m = -3 - y / -7 - (-1)

→ 1 = -(3+y)/ -7+1

→ 1 = -(3+y) / -6

→ 6 = 3 + y

→ y = 6 - 3

→ y = 3
