Answers

Answer 1

Answer:

sin J = [tex]\frac{15}{29}[/tex]

cos J = [tex]\frac{21}{29}[/tex]

tan J = [tex]\frac{5}{7}[/tex]

x = 14.6

Step-by-step explanation:

1st pic:

1st, find the missing side lenght:

[tex]a^{2} = c^{2} - b^{2}[/tex]

[tex]a^{2} = 58^{2} - 42^{2}[/tex]

[tex]a^{2} = 3364 - 1764[/tex]

[tex]\sqrt{a^{2}} = \sqrt{1600}[/tex]

a = 40

sin = [tex]\frac{opposite}{hypothenuse}[/tex] ⇒ [tex]sin J = \frac{30}{58} = \frac{15}{29}[/tex]

cos = [tex]\frac{adjacent}{hypothenuse}[/tex] ⇒ [tex]cosJ = \frac{42}{58} = \frac{21}{29}[/tex]

tan = [tex]\frac{opposite}{adjacent}[/tex] ⇒[tex]tanJ = \frac{30}{42} = \frac{5}{7}[/tex]

2nd pic:

use sine:

sin = [tex]\frac{opposite}{hypothenuse}[/tex]  

sine 59 = [tex]\frac{x}{17}[/tex]

sine of 59 is 0.857:

0.857 = [tex]\frac{x}{17}[/tex]

multiply 17 on both sides:

0.857 x 17 = [tex]\frac{x}{17}[/tex] x 17

14.569 = x

round to the nearest tenth:

14.569 = 14.6

Answer:

We know that:

PQ = p - q

Also:

PA = p - a

We are given:

PA = 1/6PQ ⇒ PQ = 6 PA

Compare the values of PQ

p - q = 6(p - a)p - q = 6p - 6a6a = 6p - p + q6a = 5p + qa = 1/6(5p + q)

What is the HCF of 108 and 270?​

Answers

Answer:

gcf, hcf, gcd (108; 270) = 54 = 2 × 3^3: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.

Step-by-step explanation:

Hope this helps :)

The highest common factor (HCF) of two given numbers is 54.

What is the highest common factor?

The largest number among all the common factors of the provided numbers is the GCF or HCF of two or more numbers. Their GCF is the largest integer that can be used to divide the two natural integers x and y without leaving any remainders.

The given numbers are 108 and 270.

The prime factors of the numbers 108 and 270 are

108=2×2×3×3×3

270=2×3×3×3×5

So, HCF is 2×3×3×3=54

Therefore, HCF of 108 and 270 is 54.

30 - 14 = 16

Lets first solve the taller one

16 * 24 = 384

Then solve the one on the left

14 * 15 = 210

Then add the both together to get the total area of the two shapes together

Solve with elimination

Answers

Answer:

5

Step-by-step explanation:

{  

3x−y=2

2x−y=3

​  

 

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

3x−y=2,2x−y=3

Subtract 2x−y=3 from 3x−y=2 by subtracting like terms on each side of the equal sign.

3x−2x−y+y=2−3

Add −y to y. Terms −y and y cancel out, leaving an equation with only one variable that can be solved.

3x−2x=2−3

Add 3x to −2x.

x=2−3

Add 2 to −3.

x=−1

Substitute −1 for x in 2x−y=3. Because the resulting equation contains only one variable, you can solve for y directly.

2(−1)−y=3

Multiply 2 times −1.

−2−y=3

Add 2 to both sides of the equation.

−y=5

Divide both sides by −1.

y=−5

The system is now solved.

x=−1,y=−5

Is it possible to add the data for an additional hike to the line plot so that the range increases but the median does not change?

Answers

Answer:

Not possible

Step-by-step explanation

Range is the difference between the highest and lowest data value in a data set. It is used to define the spread on data on the graph. Higher the range higher will be spread of data.

Whereas median is the middle value(odd number of data values) or average of the middle values(even number of data values) in a data set.

Therefore, adding an additional data value will surely change range( increase in case, the value is higher than other values) at same time it will also effect the median of the data set. So, it not possible to add the data for an additional hike to the line plot so that the range increases but the median does not change
