One fourth the sum of x and ten is identical to x minus 4."

Lynna [10]

Answer and Step-by-step explanation:

We are given the word format of an equation.

Let's right it out in numerical form.

$\frac{1}{4} (x + 10) = x - 4$

The first part says One fourth the sum of x and 10

The sum of x and 10 would be shown as x + 10, and one fourth of that means that $\frac{1}{4}$ is multiplying (x + 10).

In this case, identical would mean equal to.

So, $\frac{1}{4}$ (x + 10) would be = to something.

It says that it is identical to x minus 4 (x - 4).

$\frac{1}{4} (x + 10) = x - 4$ is the equation.

The swimming pool at Spring Valley High School is a rectangle with a width of 70 meters and a length of 30 meters. Around the pe

Nadya [2.5K]

The expression for the area of the rectangular swimming pool is given as follows:

A = w² + 100w + 2100.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle of length l and width w is given by the multiplication of these measures, that is:

A = lw.

In this problem, considering the width of 70 meters and a length of 30 meters, plus the floor of w meters, we have that:

l = 30 + w.

wi = 70 + w.

Hence the area is given as follows:

A = l x wi = (30 + w)(70 + w) = w² + 100w + 2100.

Two cars which are 40 miles apart start moving simultaneously in the same direction with constant speeds. If the speed of the ca

IgorC [24]

Answer:

5mph

Step-by-step explanation:

Given that two cars are 40 miles apart at the beginning.

They started at the same time with speeds 48 mph and 56 mph respectively

Since both cars are travelling in the same direction,

Relative velocity = Speed of the behind car-Speed of the first car

=56-48 =8mph

To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car

i.e. speed to be made up by the second car = 40 miles

Relative velocity per hour = 8mph

Hence time taken to catch up = $\frac{40}{8} =5mph$

Given the angles inscribed in the circle, find m ∠ DBC.

Cloud [144]

Answer:

m∠DBC = 51°

Step-by-step explanation:

Circle Theorem vocabulary

Chord: A straight line joining two points on the circle.
Inscribed angle: The angle formed when two chords meet at one point on a circle.
Intercepted arc: The arc that is between the endpoints of the chords that form the inscribed angle.

Inscribed Angle Theorem

The measure of an inscribed angle is half the measure of the intercepted arc.

Therefore:

$\sf \implies \angle DBC=\dfrac{1}{2}\:\overset{\frown}{BC}$

$\sf \implies \angle DBC=\dfrac{1}{2}\:(102^{\circ})$

$\sf \implies \angle DBC=51^{\circ}$

The 67 is between which of the following integers?

Vlad1618 [11]

Answer:

8 and 9

Step-by-step explanation:

8² = 64, and 9² = 81. Equivalently, √64 = 8 and √81 = 9. Since 67 is between 64 and 81, √67 must be between 8 and 9.
