Answer:

70%

Step-by-step explanation:

14/20

Divide the top and bottom by 2

7/10

Multiply the top and bottom by 10

7*10

-----------

10*10

70/100

Percent means out of 100

70%

Answer:

70%

Step-by-step explanation:

14/20 and for a percentage it's out of 100 so 20*5 is 100. So, you would have to do 14*5 which is 70. So, it's 70%.

Formula:

a² + b² = c²

8² + 15² = c²

64 + 225 = c²

c² = 289

[tex]\sqrt{c^2} =\sqrt{289}[/tex]

Answer:

the answer is more than 6 rides

Answer:

The answer is more than 6 rides.

Step-by-step explanation:

Plan A has the same cost of $15 no matter the number of rides. It stays the same. However, Plan B has an increasing price depending on how many rides you ride. Once you reach 6 rides, which is the exact same price for both of the plans, Plan A will stay at $15 for more rides, while Plan B will continue to increase in price for more rides.

Step-by-step explanation:

Fraction is the representation of the parts of a whole number. The amount of cake ate by Norma in the lunch is 9/32 parts.

Total cake left over by the Norma after the party is 3/8.

Total cake she ate for the lunch is 3/4.

The value of the whole cake is given in the fraction parts. To solve this the fraction should be understood.

Fraction is the representation of the parts of a whole number.

As the one whole of cake was there earlier. The 3/8 part of the cake is,

[tex]=\dfrac{3}{8}[/tex]

As she ate the 3/4 part of the left over cake in the lunch. Suppose the part of cake she ate is x. Therefore the part of cake she ate at lunch is,

[tex]x=\dfrac{3}{8} \times\dfrac{3}{4}[/tex]

[tex]x=\dfrac{9}{32}[/tex]

Hence, the amount of cake ate by Norma in the lunch is 9/32 parts.

Answer:

x = -4

Step-by-step explanation:

x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.

A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4

So the equation is x= -4

Answer:

  6. (A, B, C) ≈ (112.4°, 29.5°, 38.0°)

  7. (a, b, C) ≈ (180.5, 238.5, 145°)

Step-by-step explanation:

My "work" is to make use of a triangle solver calculator. The results are attached. Triangle solvers are available for phone or tablet and on web sites. Many graphing calculators have triangle solvers built in.

__

We suppose you're to make use of the Law of Sines and the Law of Cosines, as applicable.

6. When 3 sides are given, the Law of Cosines can be used to find the angles. For example, angle A can be found from ...

  A = arccos((b² +c² -a²)/(2bc))

  A = arccos((8² +10² -15²)/(2·8·10)) = arccos(-61/160) = 112.4°

The other angles can be found by permuting the variables appropriately.

  B = arccos((225 +100 -64)/(2·15·10) = arccos(261/300) ≈ 29.5°

The third angle can be found as the supplement to the other two.

  C = 180° -112.411° -29.541° = 38.048° ≈ 38.0°

The angles (A, B, C) are about (112.4°, 29.5°, 38.0°).

__

7. When insufficient information is given for the Law of Cosines, the Law of Sines can be useful. It tells us side lengths are proportional to the sine of the opposite angle. With two angles, we can find the third, and with any side length, we can then find the other side lengths.

  C = 180° -A -B = 145°

  a = c(sin(A)/sin(C)) = 400·sin(15°)/sin(145°) ≈ 180.49

  b = c(sin(B)/sin(C)) = 400·sin(20°)/sin(145°) ≈ 238.52

The measures (a, b, C) are about (180.5, 238.5, 145°).

h(a)=4a

h(4)=4(4)

h(4)=16

g(x)=x^2-1

g(8)=64-1

g(8)=63

Answer:

x = 11

Step-by-step explanation:

5x - 8 + 43 = 90

5x = 55

x = 11

Step-by-step explanation:

5x - 8° + 43° = 90° (right Angle)

5x + 35° = 90°

5x = 90° - 35°

5x = 55°

x = 55°/5

x = 11°

5x - 8 = 5 × 11 - 8 = 47°

The first angle is 47° and second one is 43°.

Answer:

like terms are terms that contains same variable

The required equivalent expression with the least number of terms has 2 terms.

A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.

Here,
If three of the terms are like terms, then we can combine them into a single term. Let's say that the expression with 4 terms is:

a + b + c + d

where a, b, and c are like terms. Then we can combine them to get:

(a + b + c) + d

which is an expression with only 2 terms.

So the equivalent expression with the least number of terms has 2 terms. We can do this by combining the like terms to simplify the expression.

Answer:

-6

Step-by-step explanation:

if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.

Answer:

-6

Step-by-step explanation:

When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.

Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.

Answer:

The 95% confidence interval for the proportion of residences that reduced their water consumption is (0.665, 0.835).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Sampled 100 residential water bills and found that 75 of the residences had reduced their water consumption over that of the previous year.

This means that [tex]n = 100, \pi = \frac{75}{100} = 0.75[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 - 1.96\sqrt{\frac{0.75*0.25}{100}} = 0.665[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 + 1.96\sqrt{\frac{0.75*0.25}{100}} = 0.835[/tex]

The 95% confidence interval for the proportion of residences that reduced their water consumption is (0.665, 0.835).
