Answer:

[tex]-\frac{8}{45}[/tex]

Step-by-step explanation:

So when multiplying fractions, you would multiply the numerator of the first fraction by the numerator of the second fraction and make that product the numerator of the resulting fraction and multiply the denominator of the first fraction by the denominator of the second fraction and make that product the denominator of the resulting fraction. In other words:

[tex]\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}[/tex]

So lets multiply the two fraction together:

[tex]\frac{4}{5}*(-\frac{2}{9})==-(\frac{4*2}{5*9})=-\frac{8}{45}[/tex]

So now we found the product. Now we have to try to try to simplify the fraction. To do this, we must find the GCF of the numerator, 8, and the denominator, 45.

Factors of 8: 1, 2, 4, 8

Factors of 45, 1, 3, 5, 9, 15, 45

As we can see, the GCF of 8 and 45 are 1. The fraction is simplified as much as possible.

I hope you find my answer and explanation to be helpful. Happy studying. :)

Answer:

  23.  42 m^2

  24.  144 ft^2

  25.  68 cm^2

Step-by-step explanation:

The teacher should not need to spend any time teaching this. The area of the total figure is the sum of the areas of its parts. You already know that. And, you already know how to compute the areas of triangles and rectangles.

__

You may recall that the area of a triangle is ...

  A = 1/2bh

and the area of a rectangle with the same base and height is ...

  A = bh

So, a triangle with base b and height h has the same area as a rectangle with the same base (b) and half the height (h/2). Recognizing this makes these problems really simple.

__

23. The base of the rectangle and triangle is 7 m. The height of the triangle is 4 m, so its area is equivalent to adding 4/2 = 2 m to the 4 m height of the rectangle. Then the total area is ...

  A = (7 m)(4 m +(1/2)(4 m)) = (7 m)(6 m) = 42 m^2

__

24. Since there are two identical triangles of height 5, their total area is equal to that of a rectangle of height 5.

  A = (12 ft)(7 ft +5 ft) = 144 ft^2

__

25. The 5 cm height of the triangle makes it have an area equivalent to a rectangle 5/2 cm high.

  A = (8 cm)(6 cm +5/2 cm) = 68 cm^2

Note: we have read the fuzzy numbers as 8 cm wide, 6 cm high for the rectangle, and 5 cm high for the triangle. If your figure is different, please use the appropriate numbers in the calculation.

The proof that m∠2 = m∠3 in the two column proof table is; shown in the various steps and concludes with subtraction property of equality

We are given;

∠1 and ∠2 are supplements

∠3 and ∠4 are supplements

∠1 ≅ ∠4

Now, since ∠1 and ∠2 are supplements, it means that;

m∠1 + m∠2 = 180° because of the definition of supplementary angles.

Since ∠3 and ∠4 are supplements, it means that;

m∠3 + m∠4 = 180° because of the definition of supplementary angles.

We are told that ∠1 ≅ ∠4

Thus;

m∠1 + m∠2 = m∠3 + m∠1 (Substitution property of equality)

Finally, we can reduce to get;

m∠2 = m∠3 (subtraction property of equality)

Step-by-step explanation:

You can plot the points and choose the one that looks like it's in the right place for a reflection across the line. The line of reflection will be the perpendicular bisector of the segment between R and its image.

In the attached plot, we see that the third choice (point C) is the desired image of R.

Answer:

you end up with 75 divided by 3.

Step-by-step explanation:

75 divided by 3 - 8 + 8

add 60 and 15

3 - 2(4) + 2^3

multiply -2 by 4

3 - 8 + 2^3

multiply 2 by itself 3 times

3 - 8 + 8 (which gives you 3 again)

and you get 75 divided by 3

Step-by-step explanation:

Answer:

1. 0.9544

2. 0.0228

3. 0.0228

Step-by-step explanation:

The computation is shown below;

As we know that

At Normal distribution

[tex]P(X < A) = P(Z < \frac{(A - mean)}{standard deviation})[/tex]

As per the question, the data provided is as follows

Mean = 24.4 minutes

Standard deviation = 6.5 minutes

Based on the above information

P(11.4 < X < 37.4) = P(X < 37.4) - P(X < 11.4)

= P(Z < (37.4 - 24.4) ÷ 6.5) - P(Z < (11.4 - 24.4) ÷ 6.5)

= P(Z < 2) - P(Z < -2)

= 0.9772 - 0.0228

= 0.9544

2. P(X < 11.4) = 0.0228

3. P(X ≥ 37.4) = 1 - P(X < 37.4)

= 1 - 0.9772

= 0.0228

Answer:

A

Step-by-step explanation:

-4u - w = u + 6w

-4u = u + 7w  (Add w to both sides)

-5u = 7w (Subtract u from both sides)

w = [tex]-\frac{5u}{7}[/tex] (Divide both sides by 7)

Answer:

w=(-5u)/7

Step-by-step explanation:

-4u-w=u+6w

Combine like terms

-4u-u=6w+w

-5u=7w

Divide both sides by 7 to cancel it out on the right side and isolate w

(-5u)/7=(7w)/7

(-5u)/7=w

w=(-5u)/7
