y=64 degrees

Answer:

y = 64

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180

y + 37 + 79 = 180

y + 116 = 180 ( subtract 116 from both sides )

y = 64

What is the intercept from these two lines.
Please explain.

Answers

Answer:

Detailed answer in explanation.

Step-by-step explanation:

When you substitute x as 0 you'll get the y-intercept and when you do the same for y you'll get the x-intercept.

[tex]y=\frac{1}{4} x-3[/tex]

x-intercept(s): (12,0)

y-intercept(s): (0,−3)

[tex]y=-\frac{3}{2} x+4[/tex]

x-intercept(s): (8/3,0)

y-intercept(s): (0,4)

Now that we got these values you can plot them into the graph and start graphing the two lines. The lines will intersect at (4,-2) as shown in the graph attached.

Answer:

m and n are both equal to 10

Step-by-step explanation:

Because we see that the two of the angles here are 45 and 90, we know then that the third angle is also 45.  This tells us that the sides m and n are of equal length.

With that in mind, we can simply use the Pythagorean theorem to find their values:

m² + n² = (10√2)²

given that m = n, then:

m² + m² = (10√2)²

2m² = (10√2)²

2m² = 100 × 2

2m² = 200

m² = 100

m = 10

So both m and n are equal to 10.

multiple out and simplify (x+6)(x-2)

Answers

Answer:

x² + 4x - 12

Step-by-step explanation:

(x+6)(x-2)

=> (x*x) + (x*-2) + (6*x) + (6*-2)

=> (x²) + (-2x) + (6x) + (-12)

=> x² - 2x + 6x - 12

=> x² + 4x - 12

So, once you simplify this equation the answer you should get is, x² + 4x - 12.

Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape

Answers

Answer:

The mixed number is 5  2 ÷ 3

Step-by-step explanation:

The computation of the number of yards of fabric does Jacob use is shown below:

Given that there is 17 yards of fabric

And, it used one third of it

So the number of yards would be

= 17 ÷ 3

= 5 2 ÷ 3

Hence, The mixed number is 5  2 ÷ 3

Where are my smart friends?? I had $13.00. My Mom gave me $10.00. My Dad gave me $30.00. My Aunt, My Uncle, and grandma gave me $100.00. I had another $7.00. How much did I have? I won against Nancy Boyd

Answers

Answer:

This would bring you to $160.00. This is because you initially had $20.00, because of the $13 and $7. Then, your family gave you a total of $140.00, and 140 + 20 = 160.

Step-by-step explanation:

The total amount of money he had is $160 and this can be determined by using the arithmetic operations and the given data.

Given :

I had $13.00. My Mom gave me $10.00. My Dad gave me $30.00. My Aunt, My Uncle, and grandma gave me $100.00. I had another $7.00.

The arithmetic operations can be used in order to determine the total amount of money he had.

The initial amount of money he had is:

= $13 + $7

= $20

His Mom gave him $10.00. So, the total amount of money now he had is:

= $20 + $10

= $30

His Dad gave him $30.00. So, the total amount of money now he had is:

= $30 + $30

= $60

His Aunt, Uncle, and Grandma gave him $100. So, the total amount of money now he had is:

= $60 + $100

= $160

Find BC.

BC = 4.7

Step-by-step explanation:

From the question given above, the following data were:

Angle A = 21 °

Hypothenus = AC = 13

Opposite = BC =?

The length of BC can be obtained by using sine ratio as illustrated below:

Sine A = Opposite /Hypothenus

Sine 21 = BC / 13

0.3584 = BC / 13

Cross multiply

BC = 0.3584 × 13

BC = 4.7

Thus, the length of BC is 4.7

5.9 × 10⁻¹⁶

Step-by-step explanation:

To solve this, you need to  convert one of the two numbers to the same power of ten as the other.  We can do that by multiplying the first number by 10:

6.7 × 10⁻¹⁶ - 8.2 × 10⁻¹⁷

= 67× 10⁻¹⁷ - 8.2 × 10⁻¹⁷

= (67 - 8.2) × 10⁻¹⁷

The solution of the system of equation is (3,8)

Step-by-step explanation:

We are given that

[tex]y=x+5[/tex]...(1)

[tex]y=2x+2[/tex]...(2)

We have to graph the system of linear equation.

For equation (1)

Substitute x=0

[tex]y=5[/tex]

Substitute y=0

[tex]x=-5[/tex]

Therefore, we obtained two points  (0,5) and (-5,0) for equation (1).

For equation (2)

Substitute x=0

[tex]y=2[/tex]

Substitute y=0

[tex]2x=-2[/tex]

[tex]x=-1[/tex]

Therefore, we obtained two points  (0,2) and (-1,0) for equation (2).

Now, we find intersection point of two equation

Substract equation (2) from (1)

[tex]x=3[/tex]

[tex]x=3[/tex]

Substitute x=3 in equation (1)

[tex]y=3+5=8[/tex]

The intersection point of two equation is at (3,8).

Hence, the solution of given system of equation is (3,8).

x = 51°

Step-by-step explanation:

The sum of all angles in a triangle is 180°.  (Angle Sum Property)

We already know 2 angles, the right angle and the 39°.

(x + 90 + 39)° = 180°

(x + 129)° = 180°

x = (180 - 129)°

x = 51°

Answer:

X=  70.5

Step-by-step explanation:

The area of a triangle is 180

180 - 39 = 141

141/2 = 70.5

70.5 + 70.5 + 39 = 180
