100 x (425 - 125) / 125

The father would have to push the child approximately 127 times for the child to attain a height of 20feet

Data;

To calculate the number of push required, we have to write an equation to represent this.

[tex]y = 1 + 0.15x[/tex]

y = maximum number of push

x = number of times required to push

[tex]20 = 1 + 0.15x\\20 - 1 = 0.15x \\19 = 0.15x\\\frac{19}{0.15} = \frac{0.15x}{0.15} \\x= 126.6\\x = 127[/tex]

Answer:

One fifth is like  you saying one fifth of something, so if you have 3 fifths of something it's just 3 times more than one fifth.  so like 1/5 is 20% so 3/5 is 3 times more which is 60%

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

1/5 of 10 is 2,

so if you have 3/5, it is the same as 1/5 3 times.

1/5 of 10 is 2, so for 3/5 of 10 you multiply 2 by 3.

1/5 of 10 = 2

2/5 of 10 = 4

3/5 of 10 = 6

4/5 of 10 = 8

5/5 of 10 = 10

y = −x + 9

- Consider the second equation. Insert the known values of variables into the equation.

y = −7 + 9

Add −7 and 9 to get 2.

y = 2

The system is now solved.

The circumference of the circle is approximately 95.84 cm.

The formula to calculate the circumference of a circle is C = πd, where C represents the circumference and d represents the diameter of the circle.

However, in this case, only the radius (half the diameter) is given. To find the circumference, we need to double the radius and multiply it by the value of π.

Given that the radius is 30.5 cm, we can calculate the circumference as follows:

C = 2πr

C = 2 * 3.14 * 30.5

C ≈ 191.08 cm

Rounding to the nearest hundredth, the circumference of the circle is approximately 95.84 cm.

The circumference of a circle is the total distance around its outer edge. It is calculated by multiplying the diameter of the circle by the value of π (pi), which is approximately 3.14.

In this case, the diameter is not provided, but the radius (half the diameter) is given as 30.5 cm.

To find the circumference, we double the radius (2 * 30.5 = 61) and multiply it by π (61 * 3.14 = 191.54).

Rounding to the nearest hundredth, the circumference of the circle is approximately 95.84 cm.

It's important to note that π is an irrational number and cannot be expressed exactly as a decimal or fraction, which is why we use an approximation like 3.14 in calculations involving circles.

Answer:

Every number to the right of 5 is greater on a number line

Step-by-step explanation:

i)

ii)

iii)

iv)

With x = -12, Not applicable so x will be 10

Length → x + 5 → 10 + 5 → 15

Breath → x -3 → 10 - 3 → 7

Therefore,

Length : 15 cm

Breadth : 7 cm

Answer:

Given:

i) Length of rectangular shaped lamina = (x + 5) cm

ii) Breadth of rectangular shaped lamina = (x - 3) cm

ii) Area of a rectangle = length × breadth

⇒ area of rectangular shaped lamina = (x + 5)(x - 3) cm²

Given:

⇒ (x + 5)(x - 3) = 105

Expand:

⇒ x² - 3x + 5x - 15 = 105

Combine like terms:

⇒ x² + 2x - 15 = 105

Subtract 105 from both sides:

⇒ x² + 2x - 120 = 0

iv) Solve x² + 2x - 120 = 0

Rewrite:

⇒ x² + 12x - 10x - 120 = 0

Break into groups:

⇒ (x² + 12x) - (10x + 120) = 0

Factorize the parentheses:

⇒ x(x + 12) - 10(x + 12) = 0

Factor out common term:

⇒ (x - 10)(x + 12) = 0

Therefore,

x - 10 = 0  ⇒  x = 10

x + 12 = 0  ⇒  x = -12

As length is positive, x = 10 only

Therefore,

Length of rectangular shaped lamina = 15 cm

Breadth of rectangular shaped lamina = 7 cm

Answer:

2, because 100,000 is said one hundred thousand which means 1 is in the hundred thousand place, and the same applies to this number meaning 2 is in that place.

Step-by-step explanation:

Answer:

2 is in the hundred-thousands place.

By solving a system of equations, we will see that the values of n and m are 3 and -4.

We need to get two values n and m such that:

n*m = -12

n + m = -1

So this is a system of equations, to solve it, we first need to isolate one of the variables in one of the equations. I will isolate n on the second equation:

n = -1 - m

Then, replacing that on the other equation we get:

(-1 - m)*m = -12

-m - m^2 = -12

-m^2 - m + 12 = 0

This is a quadratic equation, the solutions are given by Bhaskara's formula:

[tex]m = \frac{-(-1) \pm \sqrt{(-1)^2 - 4*(-1)*12} }{2*-1} \\\\m = \frac{1 \pm 7}{-2}[/tex]

Now, let's take the first solution for m:

m = (1 + 7)/-2 = -4

Then the value of n is the other solution, (or we can use the equation for n that we found above):

n = -1 - m = --1 - (-4) = 3

Then the two numbers are 3 and -4, meaning that the correct option is the first one.
