1kg bag of mortar contains 250g cement, 650g sand and 100g lime. What percentage of the bag is cement ?

Answers

Answer 1

The percentage of the bag that is cement is 25%

What is percentage?

Percentage basically means a part per hundred. It can be expressed in fraction form as well as decimal form. It is put Ina symbol like %.

For example, if the number of mangoes in a basket of fruit is 50 and there 100 fruits in the basket, the percentage of mango in the basket is

50/100 × 100 = 50%

Similarly, the total mass of the bag is 1kg, we need to convert this to gram

1kg = 1 × 1000 = 1000g

Therefore the percentage of cement = 250/1000 × 100

= 1/4 × 100 = 25%

Therefore 25% of the bag is cement.

Why does the sin 0 = cos (90 - 0)?

Answers

Answer:

It is a nonexistent circumstance where one point of a correct triangle gets zero. Attempt to think. At the point when the point becomes zero, at that point the base gets 0, and the opposite and the hypotenuse turns into a similar line. Since in cos 90, base is 0, in this manner consequently cos 90 is zero.

Draw the image of the following segment after a dilation centered at the origin with a scale factor of 2/3

Answers

Answer:

When we have a point (a, b) and we have a dilation of scale factor K centered at the origin, the new coordinates of this point will be:

(K*a, K*b)

In this case, we can find the original coordinates of the endpoints of the original segment.

Then apply the dilation to these points, and then draw a new segment whose endpoints are the dilated points.

The endpoints of the original segment are (i can not see the image very well, so i may be wrong when noticing the points).

The first endpoint is (6, 9) and (12, 12)

Now we apply a dilation with a scale factor K = 2/3.

then we get the points:

((2/3)*6, (2/3)*9) = (4, 6)

and the other point is:

((2/3)*12, (2/3)*12) = (8, 8)

Now we need to draw a segment whose endpoints are (4, 6) and (8, 8)

The segment can be seen in the graph below.

Write an equation of a line perpendicular to x = -7 and passes through the
point (4,9).

Answers

Answer:

y = 9

Step-by-step explanation:

The line x = -7 is a vertical line, so the perpendicular line will be horizontal.

Horizontal lines have a slope of 0.

Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation

y = mx + b

9 = 0(4) + b

9 = b

Plug this and the slope into the equation:

y = mx + b

y = 0x + b

y = 9

So, y = 9 is the equation

Christie has $3.80 in quarters and dimes. She has three more dimes than quarters. How many of each coin does she have?

Answers

Answer:

Quarters = 10

Dimes = 13

Step-by-step explanation:

Given that :

Quarters = $0.25

Dimes = $0.10

Total value =. $3.80

Let :

Quarters = a

Dimes = a + 3 (3 more dimes Than quarters)

0.25a + 0.10(a + 3) = 3.80

0.25a + 0.10a + 0.3 = 3.80

0.35a = 3.80 - 0.3

0.35a = 3.5

a = 3.5 / 0.35

a = 10

Quarters = a = 10

Dimes = a + 3 = 10 + 3 = 13
