36÷(9÷3/4)-2.4 find the answer

Answer:

Roughly 10%

Step-by-step explanation:

We just need to reduce this fraction: 13/119

It is in the lowest terms already, so now we need to make this fraction a percent.

13/119 = 10.12

10.12 ≈ 10%

Answer:

  (a)  135

  (b) 28%

Step-by-step explanation:

We can write equations relating pears to oranges, solve them, and then find the number of apples. Let p, o, and 'a' represent the numbers of pears, apples, and oranges.

  p/o = 5/3 . . . . . the ratio of pears to oranges is 5:3

  p -o = 54 . . . . . there are 54 more pears than oranges

  a -o = 3 . . . . . .  there are 3 more apples than oranges

__

Multiply the first equation by 3/5o to get ...

  3/5p = o

Substitute that into the second equation:

  p -(3/5)p = 54

  2/5p = 54 . . . . . . simplify

  p = 54(5/2) = 135 . . . . multiply by 5/2 to get the number of pears

There are 135 pears in the basket.

__

  a = 3 +o = 3 +3/5p = 3 +3/5(135) = 3 +81 . . . . solve for the number of apples

  a = 84

The percentage of fruits that are apples is ...

  apples/total = 84/(135 +81 +84) = 84/300 = 28/100 = 28%

  28% of the fruits are apples

Answer:

65cm

Step-by-step explanation:

100cm= 1 metre

?=2.5m

=2.5*100=250cm

250-(60+35+90)=65cm

remaining length=65cm

The value of x is 17.6. She should have added 5.4 on both sides to get the correct value of x. Then the correct option is A.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Kaitlyn solved the equation for x using the following calculations.

[tex]\rm -5.4 + x =12.2[/tex]

and she did the calculation will be

[tex]\rm -5.4x = 6.8[/tex]

The mistake she did in this equation is the plus sign is removed between the -5.4 and x. And she subtracted 5.4 from 12.2.

The correct solution of the equation is to add both sides 5.4. Then we have

[tex]\begin{aligned} \rm -5.4 + x+5.4 &=12.2+5.4\\\\\rm x &= 17.6\end{aligned}[/tex]

Answer:

y = 6

Step-by-step explanation:

- x + 3y = 9 ( add x to both sides )

3y = 9 + x → (1)

y = [tex]\frac{2}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )

3y = 2x → (2)

substitute 3y = 2x into (1)

2x = 9 + x ( subtract x from both sides )

x = 9

substitute x = 9 into (1)

3y = 9 + 9 = 18 ( divide both sides by 3 )

y = 6

A geometric series is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed constant. This constant is called the common ratio, and it is denoted by the letter "r".

The formula for the sum of the first n terms of a geometric series is:

S_n = a(1 - rⁿ)/(1 - r)

where S_n is the sum of the first n terms, a is the first term of the sequence, r is the common ratio, and n is the number of terms in the series.

The number of grains of wheat on each square of the board can be found by raising 2 to the power of the square number minus 1. For example, the number of grains of wheat on the first square is 2⁰ = 1, the number on the second square is 2¹ = 2, the number on the third square is 2² = 4, and so on.

So, the total number of grains of wheat on the board is the sum of 2⁰ + 2¹ + 2² + ... + 2⁴⁸. This is a geometric series with first term 1 and common ratio 2. Using the formula for the sum of a geometric series, the total number of grains of wheat is:

2⁰ + 2¹ + 2² + ... + 2⁴⁸ = (2⁴⁹ - 1)/(2 - 1) = 2⁴⁹ - 1

This is approximately 5.6 x 10¹⁴ grains of wheat in scientific notation.

A convex pentagon has interior angles that measure 60, 80, 120, and 140. What is the measure of the fifth interior angle?

Given -

To Find -

Solution -

Let us assume fifth interior angle as x

We know,

Sum of interior angles of a pentagon is 540°

60° + 80° + 120° + 140° + x° = 540°

→ 400° + x° = 540°

→ x° = 540° - 400°

→ x = 140°

Fifth interior angle of a pentagon = 140°

Math literacy (also known as numeracy) means having the ability to problem-solve, reason, and analyze information.

Step-by-step explanation:

Answer:

C. 7

Step-by-step explanation:

Points J and K are midpoints of the sides of triangle FGH.

=> JK = 1/2FG

2y + 5 = 1/2(5y + 3)

4y + 10 = 5y + 3

5y - 4y = 10 - 3

y = 7

The value of y is 7 for the given triangle.

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

We know that GJ = JH, and HK = KF.

Also, J and K are midpoints of GH and HF, respectively.

Therefore, we can say that:

GJ + JH + HK + KF = GF

2(GJ + HK) = GF

2(2y + 5) = 5y + 3

4y + 10 = 5y + 3

y = 7

Therefore, the value of y is 7.

Step-by-step explanation:

The value of x for which this model will make the least sense to use is at x=-2.75 seconds.

A function assigns the value of each element of one set to the other specific element of another set.

The function that is given to us is h(x) = –16x²+100 where x is the time in seconds.

Now, use the function to know the height of the object, therefore, the height of the object can be written as,

Time, t₁=0

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0)=0+100\\\\h_1=100[/tex]

Thus, the height of the object when the time is 0 seconds is 100.

Time, t₂=0.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0.5)=-4+100\\\\h_2=96[/tex]

Thus, the height of the object when the time is 0.5 seconds is 96.

Time, t₃=1

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1)=-16+100\\\\h_1=84[/tex]

Thus, the height of the object when the time is 1 second is 84.

Time, t₄=1.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1.5)=-36+100\\\\h_4=64[/tex]

Thus, the height of the object when the time is 1.5 seconds is 64.

Time, t₅=2

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(2)=0+100\\\\h_5=36[/tex]

Thus, the height of the object when the time is 2 seconds is 36.

Now as we can see that the error in the height of the object can be a maximum of 1, therefore, for different values of x, the change in height will be,

Time, t₆= -2.75

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(-2.75)=-121+100\\\\h_6= -21[/tex]

Thus, the height of the object when the time is -2.75 seconds is -21.

Hence, the value of x for which this model will make the least sense to use is at x=-2.75 seconds.
