Please help, will mark brainliest to correct answer!

Answers

Answer:

w = 15

Step-by-step explanation:

We have an expression and are asked to solve for w.

-19w + 11 = -17w - 19

Subtract 11 from both sides :

-19w = -17w - 30

Add 17w to both sides :

-2w = -30

Divide -2 from both sides to isolate w :

w = 15

x=10/3 x=10,y=30/3 x=30.y=10/3

Answers

Answer:

Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj

where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)

sin(30) = 1/2 = 17/y

y = 17(2) = 34

tan(30) = 1/sqrt(3) = 17/x  

x = 17sqrt(3)

So the answer is (d)

Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

Someone help me I don’t know how to do this

Answers

Answer:

17 and 59

Step-by-step explanation:

90-75=17 first one

180-121=59 second one plz give me brainnessttttt pllzzzz

Hey there!

So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.

The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.

Remember:

A complementary angle is made of up TWO angles that add up to 90 degrees.

A supplementary angle is made up of TWO angles that add up to 180 degrees.

N a certain​ year, the amount A of garbage in pounds produced after t days by an average household is given by Aequals 7.5t.

Answers

Answer:

The answer is below

Step-by-step explanation:

In a certain​ year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.

Plot a graph for t > 0

how many days it will take to get 200 pounds of garbage.

Solution:

a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:

At t = 0; A = 7.5(0) = 0

At t = 10; A = 7.5(10) = 75

The graph was plotted using the geogebra online graphing tool.

b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:

A = 7.5t

t = A / 7.5 = 200 / 7.5

t = 26.67 days

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(-4.2w-7x-5.4)

Answers

Answer: 4.2*w + 7*x + 5.4

Step-by-step explanation:

Here we need to remember how the product of different signs works, here is the rule:

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Now we want to distribute the negative sign in the equation:

"-(-4.2w-7x-5.4)"

We can write this as:

-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)

Now we can distribute the "-1"

Then we get:

(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)

We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:

(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4

f(x)=6^x for x=2 help please

Answers

9514 1404 393

Answer:

  f(2) = 36

Step-by-step explanation:

Put 2 where x is and do the arithmetic.

  f(2) = 6^2

An exponent of 2 means 6 is a factor two times.

  f(2) = 6×6

  f(2) = 36

Answer:

36

Step-by-step explanation:

To evaluate f(x) = 6^x at x = 2, substitute 2 for x:

f(2) = 6^2 = 36

Given

Expand parenthesis

2·6x+2·5=(-3)·(-4x)+(-3)·3

12x+10=12x-9

Subtract 12x on both sides

12x+10-12x=12x-9-12x

10=-9

10 will never equal -9, which means this is No Solution

Answer:

Step-by-step explanation:

- * + = -

- * - = +

+ * + = +

2 (6X + 5) = -3 (-4X+3)

- distribute

12X + 10 = 12X - 9

       -10            -10

12X = 12X - 19

- 12X   - 12 X

0 ≠ - 19

or you can skip all of that and just realize that there cannot be the 12X on both sides but the second term is different

What is the mean of the values in the dot plot?



Enter your answer in the box.

Answers

Answer:

The mean is 46.

Step-by-step explanation:

To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.

40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50

Multiply what's in the parentheses.

40 + 82 + 45 + 96 + 147 + 50

Add, going from left to right

122 + 45 + 96 + 147 + 50

167 + 96 + 147 + 50

263 + 147 + 50

410 + 50

460

Now, divide that by how many dots there were (10).

460/10

The mean of the values in this dot plot is 46.

Explanation:
Here we see that there are 3 B’s being multiplied against each other. This can be written as b^3, because b^3 also represents b*b*b.
Next, there are two c’s being multiplied against each other. This can be written as c^2, because c^2 also represents c*c.
Now that we have found what the exponents are we can multiple both b^3 and c^2 to get our final answer of:
b^3 * c^2
