If cos 67 degrees is close to 2/5 which is closest to the length of no
PO=100cm
P=23 degrees

Answers

Answer 1

Answer: Sin 23 = 2/5

Step-by-step explanation:

If cos 67 degrees is close to 2/5. That is, approximately,

Cos 67 = 2/5

Multiply the numerator and the denominator by 50

Cos 67 = 100/250

From trigonometry ratio,

Cos Ø = adjacent/hypothenus

Where the

Adjacent length = 100 cm

Hypothenus length = 250 cm

Po = opposite length = 100cm

If the degree = 23

The closest length will be

Sin Ø = Opposite/ hypothenus

Sin 23 = 100/250

Divide both the numerator and the denominator by 50

Sin 23 = 2/5

What is Exponential Form?

The exponential form is an easier way of writing repeated multiplication involving base and exponents. It has a base and a power

The exponential form of a number is a way of representing a number using exponents, where the base is typically a number greater than 1.

It is often used in mathematics and science to represent large or small numbers more efficiently. It can also be used to simplify certain mathematical operations, such as multiplication and division, by using the properties of exponents.

Given data ,

Let the first number be p = 6.1 x 10⁷

Let the second number be q = 2.1 x 10⁻⁴

And , the exponents are divided and the value of n is

To estimate how many times larger 6.1 x 10⁷ is than 2.1 x 10⁻⁴, we can divide the two numbers and then round the result to the nearest whole number.

n = 6.1 x 10⁷ / 2.1 x 10⁻⁴ ≈ 290,476,190,476.19

Rounding this to the nearest whole number gives us:

n ≈ 290,476,190,476

Hence , we can estimate that 6.1 x 10⁷ is approximately 290,476,190,476 times larger than 2.1 x 10⁻⁴

Find the number of x-intercepts of the graph of the function: y = 4x^2 + 4x + 1

Answers

Answer:

There is only one x intercept: x = -0.5 or -1/2

Step-by-step explanation:

To find the x-intercepts of the graph of the function, we need to find the values of x where y = 0. In other words, we need to solve the equation 4x^2 + 4x + 1 = 0 for x.

4x^2 + 4x + 1 = 0

(2x+1)^2 = 0

2x + 1 = 0

2x = 0 -1

x = -1/2

X is equal to 1/2 or 0.5

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

The required point slope form of the relationship is y = 3x/4 + 17.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope for the relationship is given  by,
m = 21.5 - 20/6 - 4
m = 1.5 /2
m = 3/4
Now, line consist a point (4, 20)
So the point slope form is given as
y - y₁ = m (x - x₁)
Substitute the value in the above equation,
y - 20 = 3/4(x - 4)
y = 3x/4 + 17

Thus, The required point slope form of the relationship is y = 3x/4 + 17.

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Help??

Answers

4 cups of unpopped corn is required to make 1 bag of popped corn.

According to the statement

we have given that the Hruses 15/4 cup of unpopped corn to make 15 bags of popped corn.

And we have to find that the with how many cups he make 1 bag of the popcorn.

So, For this purpose, we use division rule

Hruses 15/4 cup of unpopped corn = 15 bags of popped corn

Then

cups used by hurses to make 1 bag of popped popcorn = given bag of popped corn / given cups used to make popped corn

So,

cups used by hurses to make 1 bag of popped popcorn = 15 bags / (15/4) cups used

cups used by hurses to make 1 bag of popped popcorn = 15*4 /15

Then

cups used by hurses to make 1 bag of popped popcorn = 4.

So, 4 cups of unpopped corn is required to make 1 bag of popped corn.

Which system of equations has a solution of (–3, –1)? NO LINKS OR SAYINGS

B: y = –3x – 1

C:y = 2x – 1
y = 5x + 2

D:
y = 2x + 5
y = 5x + 14

Answers

The answer is b my friend
The answer is D. First you distribute 5 to the top equation so the two x variables can cancel out.
5(y=2x+5) the result would be 5y=10x+25

Then take the other equation and distribute -2 into it since a negative and positive cancel out. It would look like this:
-2(y=5x+14) the final product would be -2y=-10x-28
With this you can now add the two equations. So,,
+5y=10x+25
-2y=-10x-28
You add the like terms and end up with 3y=-3. Divide the 3 from 3y to the other side This gives you the y value(-1).You can now look for the x value by replacing the y from one of the two equations. You add like terms and end up with a x value of -3.
In conclusion the answer to your question is D. Y=2x+5. Y=5x+14

Here is a flower made up of yellow hexagons, red trapezoids, and green triangles. How many copies of this flower pattern could you build if you had 6 yellow hexagons, 2 red trapezoids, and 9 green triangles?

Answers

Answer:

Step-by-step explanation:Answer:

Part a) You could build 5 copies of the flower pattern  

Part b) You would have 40 red trapezoids left over

Step-by-step explanation:

The complete question in the attached figure

Part a)

Let

x -----> the number of yellow hexagons

y ----> the number of red trapezoids

z ----> the number of green triangles

we know that

The flower pattern has the following ratios

Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles

1) For x=30

Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)

Verify the quantity of y needed and the quantity of z needed

Find the value of y

10 < 50 ----> is ok

Find the value of z

45<60 --->is ok

2) For y=50

Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)

Verify the quantity of x needed and the quantity of z needed

Find the value of x

150 > 30 ----> is not ok

3) For z=60

Divide 60 by 9 (remember that in one pattern there are 9 green triangles)

60/9=6.7 copies

Round down

6 copies -----> 6(9)=54 green triangles

Verify the quantity of x needed and the quantity of y needed

Find the value of x

36> 30 --->is not ok

therefore

You could build 5 copies of the flower pattern

Part b)

we know that

x:y:z=6:2:9

If you build 5 copies

1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over

2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over

3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over

therefore

You would have 40 red trapezoids left over

A woman bought some large frames for ​$10 each and some small frames for ​$5 each at a closeout sale. If she bought 27 frames for ​$​180, find how many of each type she bought. She bought ____ large frames.

Answers

Answer:

Step-by-step explanation:

This is a guessing game. You assume how much there is, and then you check. I was led to the conclusion that there are 9 large frames and 18 small frames.

Answer:

She bought 9 large frames

Step-by-step explanation:

Create a system of two equations and two unknowns (the number of small frames that we call S, and the number of large frames that we call L).

The two equations become:

(a)    L + S = 27    (since she bought 27 frames total)

(b)   10 L + 5 S = 180

Now, let's solve for S in the first equation:  S = 27 - L

ad use it to replace for S in equation (b):

10 L + 5 (27 - L) = 180

10 L  - 5 L + 135 = 180

5 L = 180 - 135

5 L = 45

L = 9

Therefore she bought 9 large frames
