Answer:

Step-by-step explanation:

Let the number of balloons be X

Xiao Duo = X

Xiao Hua = X

Xiaoduo used 16 balloons = x - 16

Xiaohua balloons x = 3 ( x - 16)

x = 3x - 48

Collect like terms

48 = 3x - x

48 = 2x

Divide both sides by 2

48/2= x

x = 24

Xiaohua has 24 balloons

Answer:

$12.40

Step-by-step explanation:

Answer:

$31.80

Step-by-step explanation:

First, find the sale price.

Normally you pay for 100% of the price. Since it is 25% off, you only pay for 75% of the price. (100%-25%=75%)

Therefore, we can multiply 75% and $40

75% * $40

Convert 75% to a decimal by dividing 75 by 100 or moving the decimal place 2 spots to the left.

75/100=0.75

75.0 --> 7.5 --> 0.75

0.75* $40

Multiply

$30

Now, find the price with tax.

You have to pay for 100% of the price, plus an additional 6% for the tax. Therefore, you are actually paying for 106% of the price (100% + 6% = 106%)

Therefore, we can multiply 106% and $30

106% * $30

Convert 106% to a decimal by dividing 106 by 100 or moving the decimal place 2 spots to the left.

106/100=1.06

106.0 --> 10.6 --> 1.06

1.06 * $30

Multiply

$31.8

Niko paid $31.80 for the game.

Answer:

(-3, -2) is the image of P(3, 2).

Step-by-step explanation:

Given: a point P with coordinates (3, 2).

To find: Image of point P after 180° counterclockwise about the origin.

Solution:

Let us have a look at the coordinates and try to learn how a coordinate is written.

(3, 2) means x coordinate or value on x axis = 3 and

y coordinate or value on y axis = 2

Please have a look at the attached image to understand how the point P is plotted on xy axis.

Point P(3, 2) lies in 1st quadrant.

When a counterclockwise rotation is given the point will move from 1st quadrant to 2nd quadrant to 3rd quadrant to 4th quadrant.

A 90° rotation will cause the point to move to 2nd quadrant from 1st quadrant.

Another 90° rotation will cause the point to move to 3rd quadrant from 2nd quadrant.

So, the image of point P will lie in the 3rd quadrant where both x and y coordinates are negative.

Hence, the image will be P'(-3, -2).

Answer/Step-by-step explanation:

Given that the side length of a squared field is represented by the expression 3 - 7x,

a. Perimeter of the squared field (expressed as a sum):

Permimeter of a square = s + s + s + s

All sides of a square are of equal length.

s = side length of the squared field = 3 - 7x

Thus,

Perimeter expressed as a sum = (3-7x) + (3-7x) + (3-7x) + (3-7x)

b. Permitted of squared field expressed as a product:

Perimeter of square expressed as product = 4(s)

s = side length of squared field = 3 - 7x

Permimeter of squared field expressed as a product = 4(3 - 7x)

c. An equivalent expression for the product in (b) can be written using the distributive property as follows:

Perimeter = 4(3 - 7x)

Perimeter = 4(3) - 4(7x)

Answer:

4 + b² = 104

Hope this helps. :)

Answer:

b^{2}  + 4 = 104.

Step-by-step explanation:

The sum of 4 and the second power of b basically means 4 + b^2.

b^2 + 4 = 104

[tex]b^{2} + 4 = 104[/tex]

b^2 = 100

b = plus or minus 10.

Answer:  B. H(t) = -6.9(t - 2.3)² + 112

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k

where (h, k) is the vertex   ⇒    k is the maximum height

the distance traveled is when y = 0     ⇒    [tex]x=\sqrt{\dfrac{-k}{a}}+h[/tex]

Given: H(t) = -7.1(t - 2.3)² + 98

maximum height (k) = 98 feet

distance traveled (x) = [tex]\sqrt{\dfrac{-98}{-7.1}}+2.3[/tex]    = 6.02 seconds

A) H(t) = -7.5(t - 2.2)² + 112

maximum height (k) = 112 feet

distance traveled (x) = [tex]\sqrt{\dfrac{-112}{-7.5}}+2.2[/tex]    = 6.06 seconds

B) H(t) = -6.9(t - 2.3)² + 112

maximum height (k) = 112 feet

distance traveled (x) = [tex]\sqrt{\dfrac{-112}{-6.9}}+2.3[/tex]    = 6.33 seconds

C) H(t) = -6.9(t - 2.4)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

D) H(t) = -7.5(t - 2.3)² + 95

maximum height (k) = 95 feet

This has a lower height than the given equation.

Answer:

[tex]x_1 = 43.5145\°[/tex]

[tex]x_2 = 316.4855\°[/tex]

Step-by-step explanation:

We have a positive value for the cosine of x, so we know that the value of x should be in the first quadrant (0 ≤ x ≤ 90) or in the fourth quadrant (270 ≤ x ≤ 360).

Now, let's find the value of x that gives cos(x) = 0.7252 using the inverse function of the cosine, that is, the arc cosine function.

The value of x can be calculated using:

[tex]x = arccos(0.7252)[/tex]

Using this function in a calculator (you may find it as: [tex]cos^{-1}(x)[/tex]), we have that:

[tex]x_1 = 43.5145\°[/tex]

So this is the value of x in the first quadrant. To find the other value of x, in the fourth quadrant, that gives the same result, we just need to calculate 360° minus the value we found:

[tex]x_2 = 360\° - 43.5145\° = 316.4855\°[/tex]

So the values of x are:

[tex]x_1 = 43.5145\°[/tex]

[tex]x_2 = 316.4855\°[/tex]

Answer:

Paul should be wearing a light jacket appropriate for about 59 F or 15 °C

Step-by-step explanation:

If it is 4:00 a.m. in Honolulu when it is 2:00 p.m. in London, then the difference between times is:

[tex]d=14-4\\d=10\ hours[/tex]

London is 10 hours ahead of Honolulu.

If Paul left Honolulu at 12:00 p.m, the corresponding time in London was:

[tex]t=12+10\\t=22 = 10:00\ p.m.[/tex]

Since he arrived in London at 1:00 p.m. at Friday, the flight time was:

[tex]F= (24-22)+13\\F=15\ hours[/tex]

The flight took 15 hours in total. If the temperature was 30°C when he boarded the flight and it decreases at a rate of 1°C per hour, the temperature when Paul arrives in London is:

[tex]T=30-(15*1)\\T=15^oC[/tex]

Converting it to Fahrenheit

[tex]T=(15*\frac{9}{5})+32 \\T=59\ F[/tex]

Paul should be wearing a light jacket appropriate for about 59 F or 15 °C

Answer:

(0, 5), (0, 1), and (3, 1).

Step-by-step explanation:

If the shape should be rotated about the y-axis to make a cone, then the shape needs to be a right triangle. It will have its length on the y-axis, and the other length either parallel to, or on, the x-axis.

Since we already have a point at (0, 5), we can have another point at (0, 1). That means that the side length is 4. Now, we can make a 3-4-5 right triangle by having another point at (3, 1).

Answer:

p(x) = (x + 1)²(5x - 1)²

Step-by-step explanation:

Since we are given the 2 zeroes, we put them into binomial form:

(x + 1)(5x - 1)

We are also given that we have the polynomial degree of 4, and both zeroes have a multiplicity of 2. Therefore, both roots are powered by 2:

(x + 1)²(5x - 1)²

When we multiply it out, we should get a polynomial with a degree of 4.

Answer:

59/130

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value

Answer: n = 20

Step-by-step explanation:

Given that the problem goes thus:

When a number, n is added to 1/5 n of itself, the outcome obtained is 24.

Mathematically,

n + 1/5 of n = 24

n + (1/5n) = 24

1n + 1/5n = 24

(5n + 1n) / 5 = 24

6n / 5 = 24

6n = 24 × 5

6n = 120

n = 120 / 6

n = 20

Answer:

£7

Step-by-step explanation:

Let's call Josh's money 'J' and Leon's money 'L'.

Then, we can write the following system of equations:

[tex]J + L = 73[/tex]

[tex](J - 5) = 1.25(L - 5)[/tex]

From the first equation, we have:

[tex]J = 73 - L[/tex]

Using this value of 'J' in the second equation, we have:

[tex](73 - L - 5) = 1.25(L - 5)[/tex]

[tex]68 - L = 1.25L - 6.25[/tex]

[tex]2.25L = 74.25[/tex]

[tex]L = 33[/tex]

[tex]J = 73 - L = 73 - 33 = 40[/tex]

At the start Josh has £40 and Leon has £33, so the difference is:

[tex]J - L = 40 - 33 = 7[/tex]
