Answer:

The answer is -33.

Step-by-step explanation:

To solve the given equation we will follow the PEDMAS rule.

PEDMAS stands for :

Solving the question by PEDMAS rule :

[tex]\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 27 - 31\Big) + 40\bigg\}}}}\end{gathered}[/tex]

[tex]\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 58\Big) + 40\bigg\}}}}\end{gathered}[/tex]

Answer:

  24 square units

Step-by-step explanation:

For such questions it is convenient to choose the "base" to be a segment that is aligned with one of the coordinate axes. Here, the horizontal segments will serve. Their length is the difference between the x-coordinates of the end points, -2 -(-6) = 4, for example.

The height is measured perpendicular to the base, so will be the difference between the y-coordinates of the horizontal segments: 2 -(-4) = 6.

The area is given by the formula ...

  A = bh

  A = 4·6 = 24 . . . square units

Miss K has already graded 10 tests and is grading 9 every hour. We will add keep adding 9 starting from 10.

Mr. T has already graded 22 tests and is grading 7 per hour. We will keep adding 7 starting from 22.

Miss K: 19, 27, 36. ( Took 3 hours to reach 36 tests)

Mr T: 29, 36. (Took 2 hours to reach 36 tests)

It will take Miss K 3 hours and Mr T 2 hours to have graded the same amount of tests (36).

Answer:

Step-by-step explanation:

Given,

Cost of 35 books Joni bought = Rs. 122,500

So,

Cost of 1 book = [tex]\frac{Rs. 122,500}{35}[/tex]

Now,

Same no. of books that Toni bought = 24

So, cost of 24 books

= [tex]\frac{Rs. 122,500}{35}[/tex] × 24

= Rs. 3500 × 24

= Rs. 84,000

Hence,

Cost of same amount of 24 books bought by Toni is Rs.84,000 (Ans)

Answer & step-by-step explanation:

Look at the equation: you can rewrite it as [tex]y= x^2+4x+4 +1 = (x+2)^2+1[/tex]

Now the first term of the sum is at worst 0 (when [tex]x=-2[/tex]) so the sum is no less than 1.

Correct answer is the last option.

Answer:

81=5+b, 81-5=b, 81-b=5

Step-by-step explanation:

We can write the equation in terms of 81, b, or 5. Let's first start by writing it in terms of 81. We are already given that 5+b=81 therefore...

5+b=81 OR 81=5+b (transitive property)

Now, let's write the equation in terms of b.

5+b=81

Subtract 5 from both sides (subtraction property of equality)

5-5+b=81-5

b=81-5 OR 81-5=b (transitive property)

Lastly, let's write the equation in terms of 5.

5+b=81

Subtract b from both sides (subtraction property of equality)

5+b-b=81-b

5=81-b OR 81-b=5 (transitive property.

hello!

the answer to your question is 41!

-----------

explanation:

- Step 1: Our output value is 100.

- Step 2: We represent the unknown value with [tex]x[/tex].

- Step 3: From step 1 above, [tex]100 = 100%[/tex]%

- Step 4: Similarly, [tex]x = 41%[/tex]%

- Step 5: This results in a pair of simple equations:

[tex]100 = 100% (1)[/tex]% (1)

[tex]x=41[/tex]% (2)

- Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both  equations have the same unit (%); we have

[tex]\frac{100}{x}[/tex] = [tex]\frac{100}{41}[/tex]

- Step 7: Again, the reciprocal of both sides gives

[tex]\frac{x}{100}[/tex] = [tex]\frac{41}{100}[/tex]

Therefore, 41% of 100 is 41.

Step-by-step explanation:

Soln

From the above diagram

Height = h = 4cm

Let a&b = upward and downward lengths respectively.

That is:

a = 13cm

b = 16cm

recall that the formula used mathematically in solving/calculating the area of a trapezium is

Area = 1/2×(a+b)×h

Area = 1/2×(13+16)×4

Area = 1/2×(29)×4

Area = (29)×2

Area = 58cm²

Answer:

c

Step-by-step explanation:

Answer:

616

Step-by-step explanation:

The equation to find the area of a trapezoid is:  A = ½ (b[tex]^1[/tex]+b²) h.

b1=43

b2=45

h=14

Plug the variables in and solve.

[tex]A=\frac{1}{2} (43+45)14[/tex]

[tex]A=\frac{1}{2} (88)14[/tex]

[tex]A=\frac{1}{2} (1232)[/tex]

[tex]A=616[/tex]

Answer:

Step-by-step explanation:

Givens

h = 14

b1 = 34

b2  = 45

Formula

A = (b1 + b2)*h /2                   Substitute into the formula

Solution

A = (34 + 45)*14/2                 Combine the brackets

A = (79) * 14/2                       Do the division

A = 79 * 7

Area = 553  cm^2

Answer:

20 cm

Step-by-step explanation:

Think of a large cone, 30 cm high, and a small cone of x height.

The scale factor of a volume of the cube of the scale factor of linear dimensions.

The cubic root of 1/27 is 1/3.

This means that the height of the small cone is 1/3 the height of the large cone.

The large cone has height 30 cm.

The small cone has height 10 cm.

30 cm - 10 cm = 20 cm

Answer: 20 cm

Answer:

yes

Step-by-step explanation:

Based on percentage composition, the mass of recycled paper in Ophelia’s paper napkins is 203 g.

A percentage gives an amount of a given quantity out of a whole value expressed in 100 units.

The total mass of the napkins = 580 g

b recycled paper in napkin = 35% of 580 g

Then;

The mass of recycled paper = 35/100 * 580 g

mass of recycled paper = 203 g

Therefore, the mass of recycled paper in Ophelia’s paper napkins is 203 g.

Answer:

1/72

Step-by-step explanation:

Probability of getting a 4 on white cube is:

P(W) · P(4) = 1/2 × 1/6 = 1/12

P(R) · P(>4) = 1/2 × 2/6 = 1/6

multiply both probabilities:  1/12 × 1/6 = 1/72
