Answer

3.2

Step-by-step explanation

8% of 40 is 3.2

so it would be 40- 3.2 and that = 36.8

Answer:

Option A, B, and C.

Step-by-step explanation:

Given, 6x ≥ 3 + 4(2x - 1),

Solve to find the correct representations given in the options.

6x ≥ 3 + 4(2x - 1)

Apply distributive property

6x ≥ 3 + 8x - 4 (option B is correct) ✅

Add like terms

6x ≥ -1 + 8x

Add 1 to both sides

6x + 1 ≥ 8x

Subtract 6x from each side

1 ≥ 8x - 6x

1 ≥ 2x (option A is correct) ✅

Divide both sides by 2

1/2 ≥ 2x/2

½ ≥ x

½ ≥ x means all possible values of x are less than 0.5. representing this inequality on a graph, we would have the directed line starting at 0.5 moving towards our left.

This make option C correct.✅

Answer:

.8345

Step-by-step explanation:

The value is approximate.

==========================================================

Explanation:

Focus on the upper triangle.

Label the unknown horizontal side as y

Use the pythagorean theorem to solve for y

a^2+b^2 = c^2

10^2 + y^2 = 26^2

100+y^2 = 676

y^2 = 676-100

y^2 = 576

y = sqrt(576)

y = 24

-----------

Now move to the bottom triangle

With respect to the reference angle, the side y = 24 is opposite this. The hypotenuse is unknown.

Use the sine rule to connect the two and solve for x

sin(angle) = opposite/hypotenuse

sin(32) = y/x

sin(32) = 24/x

x*sin(32) = 24

x = 24/sin(32)

x = 45.2899179551967 which is approximate

x = 45 rounding to the nearest whole number

Side x is approximately 45 cm long.

Note: make sure your calculator is in degree mode.

Test Number of Words Time(minutes)

A. 30. 4

B. 78. 15

C. 99. 22

Answer:

Step-by-step explanation:

To calculate Zane's unit rate/number of words per minute for which each test, we divide number of words in each test by time taken for that test

For test A, unit rate = 30 words/ 4 minutes = 7.5 words per minute

For test B, unit rate = 78 words/15 minutes = 5.2 words per minute

For test C, unit rate = 99 words/22 minutes= 4.5 words per minute

From the above Zane has the highest unit rate in test A and is therefore fastest in test A

Answer:

Combine like terms

2 + − 4

3x − 4y

Answer:

[tex]3x-4y[/tex]

Step-by-step explanation:

[tex]2x+x-4y[/tex]

If a term doesn't have a coefficient , it is considered that the coefficient is 1

[tex]2x+1x-4y[/tex]

Why is it considered that the coefficient is 1?

Remember that any term multiplied by 1 remains the same:

[tex]1.x=x[/tex]

Step 1

The equality can be read in the other way as well , so any term can be written as a product of 1 and itself:

[tex]x=1 . X \\[/tex]

Step 2

Usually, we don't need to write multiplication sign between the coefficient and the variable , so the simpler form is:

[tex]x=1x[/tex]

That is why we can write the term without the coefficient as a term with coefficient 1.

Let's go back to your problem now

Collect like terms by adding their coefficients

[tex](2+1)x-4y[/tex]

Add the numbers

[tex]3x-4y[/tex]

Kratos cicle, Rides like a GOD

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y=x-2

We know that Reflecting over the x-axis inverts the sign of the y-coordinate.

Thus, after reflecting over the x-axis, the equation would be:

-y = x - 2

Now, writing the equation in the slope-intercept form

y=mx+b

where

so the equation in the slope-intercept form

-y = x - 2

y = -x + 2

Answer:

x=3.91

Step-by-step explanation:

29.46=13.82+4x

13.82+4x=29.46

subtract 13.82 from both sides

4x=15.64

divide by 4

x=3.91

Given:

Quadrilateral ABCD has vertices A(–1, –2), B(–1, 3), C(4, 3) and D(4, –2).

It's dilated by a factor of 2 with the center of dilation at the origin.

To find:

The coordinates of the resulting quadrilateral A'B'C'D'.

Solution:

The figure dilated by a factor of 2 with the center of dilation at the origin. So, the rule of dilation is

[tex](x,y)\to (2x,2y)[/tex]

Using the above rule, we get

[tex]A(-1,-2)\to A'(2(-1),2(-2))=A'(-2,-4)[/tex]

[tex]B(-1,3)\to B'(2(-1),2(3))=B'(-2,6)[/tex]

[tex]C(4,3)\to C'(2(4),2(3))=C'(8,6)[/tex]

[tex]D(4,-2)\to D'(2(4),2(-2))=D'(8,-4)[/tex]

Therefore, the coordinates of the resulting quadrilateral A'B'C'D' are A'(-2,-4), B'(-2,6), C'(8,6) and D'(8,-4).
