Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 8160}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ \frac{2}{3} \times \frac{1}{4} \times x = 1360}[/tex]

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term

[tex] \longrightarrow{ \sf{ \frac{2 \times 1}{3 \times 4} \times x = 1360}}[/tex]

[tex] \longrightarrow{ \sf{ \frac{2}{12} \times x = 1360}}[/tex]

[tex] \longrightarrow{ \sf{ \frac{1}{6} x = 1360}}[/tex]

Solve for x

[tex] \longrightarrow{ \sf{x = 1360 \times 6}}[/tex]

[tex] \longrightarrow{ \sf{x = 8160}}[/tex]

Answer:

2 m/s²

Step-by-step explanation:

Given:

v₀ = 0 m/s

v = 4.0 m/s

t = 2 s

Find: a

a = (v − v₀) / t

a = (4.0 m/s − 0 m/s) / 2 s

a = 2 m/s²

Answer:

At the start of a race, a runner’s velocity changes from 0 to 4.0 m/s. It takes him 2 seconds to speed up. His acceleration is 2 m/s2.

Explanation:

Acceleration is the rate at which velocity changes. To find the acceleration, divide the change in velocity (final velocity − initial velocity) by the time interval. In this example, the change in velocity is 4.0 m/s in 2 seconds. So, divide 4.0 by 2.

I hope this explanation helps you understand accelerations!

Answer:

It has been proven from the explanation.

Step-by-step explanation:

If we assume that the real number x is greater than 0. Now, If on the contrary, a is less than 0, we can make the argument that;

Let us make n to be a natural number and m = m(n) to be the largest positive integer in such a way that;

m/n < x

Thus, (m+1)/n ≥ x and finally;

|x - m/n| < 1/n

If r_n = m/n. It will be easy to show from the definition of limits that the sequence (r_n) has limit x.

From earlier where we assumed that x > 0, the numbers that will be obtained by truncating the decimal expansion of "x" at the n-th place will be rational, and clearly have the limit "x". Although it implies we are now assuming every real number will have a decimal expansion.

Answer: 1 and 5/7

Step-by-step explanation: To divide mixed numbers,

first write the mixed numbers as improper fractions.

So here, we can write 2 and 4/7 as the improper fraction 18/7

and we can write 1 and 3/6 as the improper fraction 9/6.

If you need a review of how to write a mixed number

as i improper fraction, let me know below and I will help.

So here, we have 18/7 ÷ 9/6.

Remember that dividing by a fraction is the same

as multiplying by the reciprocal of that fraction.

So here, 18/7 ÷ 9/6 is the same as 18/7 × 6/9.

So now we're simply multiplying fractions.

Remember that when we're multiplying fractions,

we want to cross-cancel first whenever possible.

So here, notice that we can cross-cancel 9 and 18 to 2 and 1.

However, we can't cross-cancel 7 and 6.

So we simply multiply across the numerators

and then across the denominators and we have 12/7.

We can write 12/7 as the mixed number 1 and 5/7.

Answer:

x | y | (x,y)

0 | 35 | (0,35)

3 | 50 | (3,50)

-7 | 0 | (-7,0)

Step-by-step explanation:

Given the equation: [tex] y = 5x + 35 [/tex], to complete the table, plug in the value of x given in the table in each row, to find y.

When x = 0,

[tex] y = 5(0) + 35 [/tex]

[tex] y = 0 + 35 [/tex]

[tex] y = 35 [/tex]

(0,35)

When x = 3,

[tex] y = 5(3) + 35 [/tex]

[tex] y = 15 + 35 [/tex]

[tex] y = 50 [/tex]

(3,50)

When x = -7,

[tex] y = 5(-7) + 35 [/tex]

[tex] y = -35 + 35 [/tex]

x < -14

Step-by-step explanation:

Solve the inequality  x − 2 > 2x + 12 for x:

First, subtract x from both sides.  In the resulting inequality x is on the right side with +12:

-2 > x + 12

Subtract 12 from both sides to isolate x:

2)  in the expression.

g(2) = 2(2) -5

        Replace the function designators in h(2) +g(2) with the actual functions.

h(t) = 3 - 5 +2 (2) ← plug h(2) into 2(t)

         Remove parentheses.

3 - 5 + 2(2)

         Multiply 2 by 2

3 - 5 + 4 - 5

         Subtract  5  from  3

If your question is: Ashley can ride her bicycle 15 miles in 2 hours. There are 60 miniutes in an hour and there are 1760 yards in 1 mile. How many yards does Ashley travel each minute?

____________________________________

First, do 15 miles divided by 2 hours. In addition, do 1 hour divided by 60 minutes (1). Thus, do 1760 yards divided by 1 mile. Therefore, you can multiply these together to get 220 yards/min.

Answer:

the new height of the triangle = 2.449

Step-by-step explanation:

Given that:

the sides of the triangle are 4m in length i.e they are equal. It shows that the triangle is known to be an equilateral triangle.

Let say the triangle is a triangle IJK

Let the length of the side to be i = 4

Definitely

IJ = JK = IK = i = 4

If a midline is drawn and cuts the equilateral triangle in two equal halves of a right-angle triangle. Then, suppose the midline is L

Then ;

[tex]JL = \dfrac{1}{2} JK[/tex]

[tex]JL = \dfrac{1}{2} i[/tex]

Let consider triangle IJL

(IL)² = (IJ)² - (JL)²

[tex](IL)^2 = i^2 - \dfrac{i^2}{4}[/tex]

[tex](IL)^2 = \dfrac{3i^2}{4}[/tex]

[tex](IL) =\sqrt{ \dfrac{3i^2}{4}}[/tex]

[tex]IL =\sqrt{3} \dfrac{i}{2}[/tex]

Area of triangle IJK can be expressed as:

[tex]Area = \dfrac{1}{2}\times Base \times Height[/tex]

[tex]Area = \dfrac{1}{2}\times i \times \sqrt{3}\dfrac{i}{2}[/tex]

[tex]Area = \sqrt{3}\dfrac{i^2}{4}[/tex]

where, i = 4

Then:

[tex]Area = \sqrt{3}\dfrac{4^2}{4}[/tex]

[tex]Area = \sqrt{3} \dfrac{16}{4}[/tex]

[tex]Area =4 \sqrt{3}[/tex]

when the area is exactly half of the original triangle's area, the new height is :

[tex]A = \dfrac{1}{2} \times Area[/tex]

[tex]\sqrt{3} \dfrac{i^2}{4} = \dfrac{1}{2} \times 4\sqrt{3}[/tex]

[tex]\dfrac{i^2}{4} = \dfrac{1}{2} \times 4[/tex]

[tex]\dfrac{i^2}{4} =2[/tex]

[tex]i^2 = 8[/tex]

[tex]i= \sqrt{8}[/tex]

[tex]i= \sqrt{4 \times 2}[/tex]

[tex]i= 2 \sqrt{2}[/tex]

Finally, the new height of the new triangle is:

[tex]IL =\sqrt{3} \dfrac{i}{2}[/tex]

[tex]IL =\sqrt{3} \dfrac{2 \sqrt{2}}{2}[/tex]

[tex]IL =\sqrt{3 \times 2}[/tex]

[tex]IL =\sqrt{6}[/tex]

IL = 2.449 m

Answer:

162 square inch

Step-by-step explanation:

Area = Length * Width

Area = [tex]18*9=162[/tex]

The area of the rectangle will be 162 square inches.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

Given that a rectangle is 18 inches long and 9 inches wide.

Area = Length x width

Area = 18 x 9

Area = 162 square inches

Therefore, the area of the rectangle will be 162 square inches.

Option (3)

Step-by-step explanation:

Integers are the numbers which don't have a fractional part (having positive of negative notations)

Example; -2, -1, 0, 1, 2,...

Let the two integers are 0 and 2,

Subtraction of these integers will be = 0 - 2

                                                             = 0 + (-2)

Here opposite of 2 has been added to 0.

That means subtraction of two integers is to add the opposite of the integer being subtracted.

The open circle means you should not include the number it is on.

The inequality would look like, x<2 and not equal to. Therefore, 2 is not a solution.

Answer:

Step-by-step explanation:

When there is an open circle, it means that it can't be that exact number. If there is a closed circle, it can be that number. This is an open circle, and means that it is less than 2.
