plz help man, im frustrated and i need 1 more answer​

Answer:

C

Step-by-step explanation:

(180- 80+65 = 35) sum of the angle in a triangle.

to get the exterior angle

180 - 35 = 145 (sum of angle on a straight line is 180)

...C. 145° on Ap3x.....

Answer:

Com o aumento da população no início da Baixa Idade Média, muitas pessoas saíram do campo para viver nas cidades. Quais trabalhos eles passaram desempenhar?

Step-by-step explanation:

Answer:

65 + 65 = 130

360 - 130 = 230 degrees

Answer:

4 / 6

Step-by-step explanation:

Fred fraction = 2/3

Sarah formed a fraction by dividing her number line into 6 equal pieces. This is given as;

x / 6

Since her fraction is equal to that of fred, we have;

x / 6 = 2 / 3

x = 6 * 2 / 3 = 4

Sarah Fraction = 4 / 6

Answer:

B is the right answer and if you add

Note:

Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.

Answer:

The equation in the standard form is:

2/3x + y = -4

Please also check the attached graph.

Step-by-step explanation:

We know that the equation in the standard form is

Ax + By = C

where x and y are variables and A, B and C are constants

Given

Slope m = -2/3

y-intercept = -4

To determine

Write the equation in the standard form

We know that the slope-intercept form of the line equation

where

m is the slope

b is the y-intercept

In our case:

Slope m = -2/3

y-intercept = -4

substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation

y = mx+b

y = -2/3x  + (-4)

y = -2/3x - 4

Writing the equation in the standard form

2/3x + y = -4

Therefore, the equation in the standard form is:

2/3x + y = -4

Answer:

give the other person brainlist he/she worked hard you can tell

Step-by-step explanation:

Answer:

A, B, and E

Step-by-step explanation:

When talking about like terms you need to look at the variable. You have to look at which has the same variables and then you can determine which are like terms.

For A --> -6m + 4m both have m as a variable. They can be combined. Which is why they are like terms. Do the same for the rest.

What would NOT be like terms?

C-- 10m + mn

This is wrong because of the variable. the variable for 10m is m. When there is only a variable you can pretend there is a 1 (For example, m can be 1m but we ignore that). mn is a variable as a whole. So if we added one to the front, the variables of 10m and 1mn would not match! It does not matter if they both have an m, because the value would be different either way.

Hope this helps!!

Answer:

Step-by-step explanation:

If it is exponential dividing any term by the preceding term will be a constant, the common ratio or rate. 50/25=100/50...=2 The initial value, a, (at x=0) is 25 so the general form is

y=ar^x we have a=25 and r=2 so

y=25(2^x)

I know this

Step-by-step explanation:

but I dont :) goodluck tho

Given:

Principal = $5,000

Rate of interest = 3.2% annual interest compounded semiannually.

Time = 10 years.

To find:

The amount after compound interest.

Solution:

The formula for amount is:

[tex]A=P\left(1+\dfrac{r}{100n}\right)^{nt}[/tex]

Where, P is principal, r is rate of interest, n is number of times interest compounded and t is the number of years.

Putting P=5000, r=3.2, t=10, n=2, we get

[tex]A=5000\left(1+\dfrac{3.2}{100(2)}\right)^{2(10)}[/tex]

[tex]A=5000\left(1+0.016\right)^{20}[/tex]

[tex]A=5000\left(1.016\right)^{20}[/tex]

[tex]A=5000(1.37364389)[/tex]

On further simplification, we get

[tex]A=6868.21945[/tex]

[tex]A\approx 6868.22[/tex]

Therefore, the amount after compound interest is $6868.22.

Answer: 6000,00

Step-by-step explanation:

Answer:

Use the slope-intercept form to find the slope and y-intercept.

Slope: −3 . y-intercept: (0,4)

Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

X   Y

0    4

3/4  0

Graph the line using the slope and the y-intercept, or the points.

Slope: −3.  y-intercept: (0,4)

tan29=32/x

x=32/(tan29)

x=58m

So the boat is 58 meters from the base of the lighthouse.

Step-by-step explanation:

<7 = <2 b/c they're alternate exterior angles

Answer:

angle v = 46 degrees

Step-by-step explanation:

tan-1 = [tex]\frac{opposite}{adjacent}[/tex]

tan-1 V = [tex]\frac{21}{20}[/tex]

[tex]\frac{21}{20}[/tex] = 1.05

tan-1 V = 1.05

V = 46.397

round to the nearest whole number:

46.397 = 46

Just took the quiz.

Answer:

area = 44 cm²

Step-by-step explanation:

rectangle area = bh = 8 x 4 = 32 cm²

triangle height² = 5² - 4³ = 25 - 16 = 9

triangle height = 3

triangle area = 1/2bh = 1/2(8)(3) = 12 cm²

32 cm² + 12 cm² = 44 cm²

area = 44 cm²

Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

Answer:

what were the results it says these are the results but nothing there

Answer:

is this what you meant?

Step-by-step explanation:

Answer:

Step-by-step explanation:

You should start with 10. The problem with 10 is that if you add 4 to it, the sum is less than 15, so no triangle will form.

A and B won't work either 4 + 15 is 19. A and B are both longer than 19 so no triangle will form.

The answer has to be C. 4 and 15 make 19. That's more than 17 so a triangle will be formed.
