the hardware store sells sparklers for the 4th of july. they charge 19 cents apiece. the firework stand charges 85 cents for four. which is the better deal? how can you tell

Answers

Let’s start by finding the average for the place that charges 85 cents for 4 fireworks. You simply do 85 divided by 4 to get 21.25 cents. This means that each firework costs about 21 cents a piece. So, the first firework stand is the better deal, because 19 cents a piece is better than 21 cents a piece.

Mr. Lin baked banana bread for a bake sale to raise money for the math team. He said that he added a spoonful of walnuts for each of the students in his three classes, and that he added more than 250 walnuts. He used the inequality
16w + 24w + 10w > 250 to represent this situation, where w represents the number of walnuts in each spoonful. How many walnuts can be in a spoonful?

Answers

To answer this question you would need to solve this inequality. The first step would be to combine all three terms on the left-hand side of the greater than symbol. By doing this you would have 50w > 250. To solve this inequality divide both sides by 50. The answer is w > 5. In words, this means the number of walnuts per spoonful is greater than five.

can u show me common core way this problem how to do 5/9 ×3 1/2

Answers

1.) you want to make 3 1/2 an improper fraction. so multiply 3 times 2 (your denominator) then add 1 (numerator).
3x2= 6 6+1=7, then put 7 over your denominator which would be 7/2.
2.) multiply 5/9 times 7/2
5 times 7 is 35
9 times 2 is 18
your answer is 35/18
3.) make it a proper fraction
18 times 2 is 36 so that would't work to have two!
so you only can put 18 into 32 once so subtract 32-18 so you know what is left over after you take a whole out. 32-18=14. 14 is now the numerator and so put your whole number first then put your numerator over your denominator: 1 14/18
4.) simplify
1 14/18= 1 7/9, I divided 14 and 18 by 2 to simplify

The answer is 1 7/9

How are exponential functions related to logarithmic functions?
Model that with an example.

Answers

Exponential functions are related to logarithmic functions in that they are inverse functions. Exponential functions move quickly up towards a [y] infinity, bounded by a vertical asymptote (aka limit), whereas logarithmic functions start quick but then taper out towards an [x] infinity, bounded by a horizontal asymptote (aka limit).
If we use the natural logarithm (ln) as an example, the constant "e" is the base of ln, such that:
ln(x) = y, which is really stating that the base (assumed "e" even though not shown), that:
[tex] {e}^{y} = x[/tex]
if we try to solve for y in this form it's nearly impossible, that's why we stick with ln(x) = y
but to find the inverse of the form:
[tex]{e}^{y} = x[/tex]
switch the x and y, then solve for y:
[tex] {e}^{x} = y[/tex]
So the exponential function is the inverse of the logarithmic one, f(x) = ln x

Exponential and logarithmic functions are related in that they are inverses of each other.

Logarithmic functions and exponential functions are inverses of each other.

For instance, let [tex]log a = b[/tex]

In order to eliminate the logarithmic function, we will apply an exponential function ([tex]e[/tex])to both sides.

[tex]e^{loga} = e^b[/tex]

The exponential function will cancel out the logarithmic function since they are inverses of each other to give:

[tex]a = e^b[/tex]

This example shows the inverse relationship that exists between the logarithmic and exponential functions.

The expression 17n+11 represents the perimeter of the triangle.

A simplified expression that represents the measure of the third side is

Answers

Answer: the answer is 8n

The third side of a triangle whose perimeter is 17n + 11 and the other two sides are (5n + 6) and (4n + 6) is 8n

The perimeter of any shape is total distance around the shape

In the triangle shown:

The perimeter = 17n + 11

The first side = 5n + 6

The second side = 4n + 5

Let the third side be represented by M

The perimeter = (The first side) + (The second side) + (The third side)

Substitute perimeter = 17n + 11, first side = 5n + 6, second side = 4n + 5, and third side = M into the equation above

17n + 11 = (5n + 6) + (4n + 5) + M

M = 17n + 11 - 5n - 6 - 4n - 5

Collect like terms

M = 17n - 5n - 4n + 11 - 6 - 5

M = 8n

Therefore, the third side of a triangle whose perimeter is 17n + 11 and the other two sides are (5n + 6) and (4n + 6) is 8n

You observe one pine tree. if the probability of not being a foxtail pine is equal to 0.06, what is the probability that this tree is a foxtail pine? (calculate to 2 decimals)

Answers

the probability that this tree is a foxtail pine is
99.94%

Final answer:

The probability that the observed pine tree is a foxtail pine is 0.94 or 94%, calculated by subtracting the probability of it not being a foxtail pine (0.06) from 1.

Explanation:

If the probability of not being a foxtail pine is 0.06, we can find the probability of a tree being a foxtail pine by subtracting this from 1 (since the sum of all probabilities for an event and its complement must equal 1). Therefore, the calculation to find the probability of the tree being a foxtail pine is 1 - 0.06.

Carrying out this subtraction gives us:

1 - 0.06 = 0.94.

Thus, the probability that the observed pine tree is a foxtail pine is 0.94, or 94%, when calculated to two decimals.

Answers

If something 20% of its normal value, then it has been divided by 5 (using the example of 100%, if you divide this by 5 it leaves you with 20%). This means that 10 beats per minute are only a fifth of its usual heart rate. Therefore a grizzly bear's normal heart rate is 10 × 5 = 50 beats per minute.

5. What is the value of x to the nearest tenth? The figure is not drawn to scale.
A) x=15.7
B) x=4.4
C) x=13.9
D) x=1.9

Answers

we know that
x/8.3=14.8/7.8
x=(14.8/7.8)*8.3------> 15.74-------> x=15.7

the answer is
the option
x=15.7

The correct option is B) [tex]x=4.4[/tex]. The value of x to the nearest tenth is x=4.4.

To find the value of x, we need to apply the Law of Cosines to the given triangle. The Law of Cosines states that for any triangle with sides [tex]$ a $, $ b $, and $ c $,[/tex] and the angle opposite side c and [tex]$ \gamma $,[/tex] the following relationship holds: [tex]\[ c^2 = a^2 + b^2 - 2ab\cos(\gamma) \][/tex]

Let's denote the sides of the triangle as follows: the side opposite the right angle (hypotenuse) as c, the side opposite the 30-degree angle as b, and the side opposite the 60-degree angle as a. We are given that [tex]$ a = 2x $, $ b = x $, and $ c = 10 $.[/tex]

Using the Pythagorean theorem, we have:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

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

[tex]\[ 100 = 4x^2 + x^2 \][/tex]

[tex]\[ 100 = 5x^2 \][/tex]

[tex]\[ x^2 = \frac{100}{5} \][/tex]

[tex]\[ x^2 = 20 \][/tex]

[tex]\[ x = \sqrt{20} \][/tex]

[tex]\[ x = \sqrt{4 \cdot 5} \][/tex]

[tex]\[ x = 2\sqrt{5} \][/tex]

Now, we calculate the numerical value of x:

[tex]\[ x \approx 2 \cdot 2.236 \][/tex]

[tex]\[ x \approx 4.472 \][/tex]

Rounding to the nearest tenth, we get: [tex]\[ x \approx 4.4 \][/tex]

Therefore, the value of x to the nearest tenth is 4.4, which corresponds to option B.

C. It is not possible because if a triangle has a right triangle, that means all the angles are right angles. Its is possible. The classmate is correct.

Answers

Final answer:

A triangle cannot have both a right angle and an obtuse angle, as the sum of its angles must always equal 180 degrees.

Explanation:

To convince your classmate that a triangle cannot have both a right angle and an obtuse angle, you should explain that according to Euclidean geometry, the sum of the angles in any triangle must equal two right angles, or 180 degrees.

If a triangle has a right angle (90 degrees), then the remaining two angles must sum up to 90 degrees as well. Introducing an obtuse angle, which is any angle greater than 90 degrees, would cause the total sum of the angles to exceed 180 degrees, which is impossible.

Therefore, the correct statement to use would be 'A. It is not possible because the sum of the angles in the triangle can't exceed 180 degrees.'

what is the solution of the equation 1.6m - 4.8 = -1.6m

Answers

Solve for m:
1.6 m - 4.8 = -1.6 m

Add 1.6 m to both sides:
1.6 m + 1.6 m - 4.8 = 1.6 m - 1.6 m

1.6 m - 1.6 m = 0:
1.6 m + 1.6 m - 4.8 = 0

1.6 m + 1.6 m = 3.2 m:
3.2 m - 4.8 = 0

Add 4.8 to both sides:
3.2 m + (-4.8 + 4.8) = 4.8

4.8 - 4.8 = 0:
3.2 m = 4.8

Divide both sides of 3.2 m = 4.8 by 3.2:
(3.2 m)/3.2 = 4.8/3.2
