1.V Diferența a două numere este 38, iar descăzutul este 76. Scăzătorul este:

a. 38;

b. 29;

d. 83.

-

C. 114;

Answers

Answer 1

Răspuns:

38

Explicație pas cu pas:

Dat fiind :

Diferența dintre numere = 38

Subtractorul = x

Scădere = 76

Diferența dintre numere;

Scădere - scădere = diferență

76 - scădere = 38

76 - 38 = subtractor

Subtractor = 38

If f(x)= -2x+3 , find f(-1)?

Answers

Before we solve the equation let's take a look at it.

f(x) = -2x + 3

See how x appears in both f(x) and as the variable in the second half of the equation?

f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.

So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."

Catching on? We need to replace x with -1 to solve for f(-1).

So here we go:

f(x) = -2x + 3

f(-1) = -2(-1) + 3

f(-1) = 2 + 3

f(-1) = 5

Voilà! We have solved for f(-1). Hope this helped.

Answer:

41.13

Step-by-step explanation:

The figure is basically 8+8+circumference of a circle with 8 diameter. The circumference is 2pi(4) which is 50.27, and you add 16 to that. This gives you the answer 41.13

Thanks to garden555 for pointing out my mistake.

Answer:

60m / 41.12 m

Step-by-step explanation:

side of square is 8m

hence, radius of the semicircle is 1/2 of 8

= 4m.

2semicircles = 1 circle.

perimeter of a circle = 2πr

Taking value of π as 22/7,

= 2 x 22/7 x 4

= 176/4

= 44m

OR

Taking value of π as 3.14,

= 2 x 3.14 x 4

= 25.12m

hence, perimeter of figure is,

44 + 8 + 8 = 60m

OR

25.12 + 8 + 8 = 41.12 m

Juanita is riding her bicycle on a trail at the rate of 0.3 kilometers per
minute. Michelle is 11.2 kilometers behind Juanita when she starts traveling
on the same trail at a rate of 0.44 kilometers per minute. Let d represent
the distance in kilometers the bicyclists are from the start of the trail and t
represent the time in minutes. The situation can be represented by the
following system; d=0.3t+11.2 and d=0.44t. How many minutes will it take
Michelle to catch up to Juanita? How far will they be from the start of the
trail? Use the substitution method to determine your answer.

Answers

Answer:

It will take Michelle 80 minutes.

They're 35.20 kilometers away from their starting point.

Step-by-step explanation:

We have to find how many minutes it would take Michelle to catch up to Juanita.

We know that Michelle's movement is represented as: d = 0.44t

Juanita's movement is represented as: d = 0.3t + 11.2

To find how many minutes it would take for Michelle to catch up, we will have to solve both equations together and solve for "t", or time.

Solve:

0.44t = 0.3t + 11.2

Subtract 0.3t from both sides.

0.14t = 11.2

Divide both sides by 0.14

t = 11.2/0.14

t = 80

This means that it would take 80 minutes for Michelle to catch up.

To find how far they are, multiply 0.44 by 80.

0.44 · 80 = 35.20

This means that they're 35.20 kilometers away from their starting point.

The price, P, of a sweater was discounted by 10% in

February. Because the sweater did not sell by the end of

the winter season, it was discounted by another 20% in

March. In terms of P, what was the price of the sweater

after the discount in March?

Answers

Answer:

In terms of P, the price of the sweater after the discount is 0.72P.

Step-by-step explanation:

Since the price P would represent 100% and the price was discounted by 10%, you can calculate 10% of 100% and subtract that amount, which would be:

100*10%=10

100-10=90%

This means that the price paid would be 90% of P. Then, the statement says that the price was discounted by another 20%. So, you have to calculate 20% of the price and subtract that amount from the price:

90*20%=18

90-18=72%

According to this, this means that in terms of P, the price of the sweater after the discount is 0.72P.

UKMT Q8??? I have inserted the photo of the question

Answers

Answer: The distance is 15 units.

Step-by-step explanation:

Let's define the bottom left corner of the left rectangle as the point (0, 0).

we know that the rectangles are of 10 by 14, then the point O will be exactly on the middle of these two quantities (because the long side is on the horizontal axis, the point O could be written as):

O (7, 5)

Point M is on the top of the rectangle, then we know that the y component will be equal to 14.

And the x component is on the middle of the rectangle (this side is the one that measures 10 units)

the middle is 5.

And we also need to add the 14 units of the other rectangle that is lying down, then the x-component of this rectangle is 14+ 5 = 19

The point M is (19, 14)

We want to find the distance between the points (7, 5) and (19, 14)

We know that the distance between points (a, b) and (c, d) is:

Distance = √( (a - c)^2 + (b - d)^2)

In this case, the distance between points O and M will be:

distance = √( (7 - 19)^2 + (5 - 14)^2) = 15

Distance between points O and M is 15 units.

The diameter of a circle is 9 cm. Find its area to the nearest tenth.

Answers

63.6 cm

Cut diameter in half to find radius

9/2 = 4.5

radius = 4.5

This is the formula for area of a circle:

pi * radius^2

pi * 4.5^2

20.25pi

Now find pi:

20.25 * pi = 63.6

Answer:

63.6 cm is the area

Answer:

63.6

Step-by-step explanation:

1. A = πr²

2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5

3. Now that we know the radius, we plug it into our formula: A = π(4.5)²

4. Simplify: A = 3.14(20.25)

5. A = 63.62

6. Rounding to the nearest tenth makes your answer 63.6
