Answer:

The rectangle is being reduced by a scale factor of 3/4, which means each side is reduced by the scale factor of 3/4. Therefore, we have 8* (3/4) = 6, and 20* (3/4) = 15. So, the new side lengths are 6 and 15, and so the area is 90 (6x15).

Answer:

90 cm^2

Step-by-step explanation:

The side lengths are reduced by 3/4

8 * 3/4 = 6

20 * 3/4 = 15

The new side lengths are 6 cm by 15 cm

The area is

A = l * w

A = 6*15 = 90 cm^2

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

C. 69°

Step-by-step explanation:

All three angles of a triangle add to 180°. You are given that one angle is 42° and for a isosceles triangle, the two remaining angles in the photo are equal so:

180° = 2x - 42°

138° = 2x

x = 69°

If you have any questions, please leave a comment.

Answer: The answer would be c.69

Step-by-step explanation:

180° = 2x - 42°       138° = 2x        x = 69°

Answer:

It will take 15 hrs.

Step-by-step explanation:

The train travels at 5.5km per hour.

We know that in x hours it will advance by x*5.5 km.

Hence we need to solve x*5.5=82.5, hence x=82.5/5.5=15.

Answer:10

Step-by-step explanation: this is a middle school question? lool

We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.

If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.

The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.

To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:

s * $2.25 = $32

s = $32 / $2.25

s = 14.22

Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.

Answer:

If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

1. 31*9 = 279          

George has 279 marbles at home.

2. 49 + 97 = 146    

They have 146 marbles altogether.

3. 327 - 139 = 188  

Ashley has 188 more than Amber.

4. 111 - 56 = 55

He has 55 more marbles left.

5. 47*28 = 1316

Room 15 has 1316 marbles.

6. 1110/30 = 37

The average each child contributed would be 37 marbles.

7. 1056/11 = 96

Each boy received 96 marbles.

Answer:

45

Step-by-step explanation:

Note that \(\cos a=\frac{4}{5}\). Since \(-\pi<a<0\), [tex)\sin \alpha<0\). So, by the Pythagorean theorem, \(\sin \alpha=-\frac{3}{5}\).

\(c=\cos \left(a+\frac{\pi}{6} \right) \\ \\ c=\cos a \cos \frac{\pi}{6}-\sin a \sin \frac{\pi}{6} \\ \\ c=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}+\frac{3}{5} \cdot \frac{1}{2} \\ \\ c=\frac{4\sqrt{3}+3}{10} \\ \\ \therefore 10c=4\sqrt{3}+3\)

Note that \(\cos b=\frac{4}{5}\) and that \(0<b<\pi\), meaning \(\sin b>0\). So, by the Pythagorean identity, \(\sin b=\frac{3}{5}\).

\(d=\cos \left(b+\frac{\pi}{6} \right) \\ \\ d=\cos b \cos \frac{\pi}{6}-\sin b \sin \frac{\pi}{6} \\ \\ d=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}-\frac{3}{5} \cdot \frac{1}{2} \\ \\ d=\frac{4\sqrt{3}-3}{10} \\ \\ \therefore 10d=4\sqrt{3}-3\)

He read 2/8 hour on Tuesday.

To find the difference we must subtract Monday's time from Tuesday's time: 7/8-2/8 = 5/8

He read for 5/8ths of an hour
