Answer:
Jason has $58.20 and Jeff has $13.80.
Step-by-step explanation:
Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.
We know that together they have $72. So, we can write the following equation:
[tex]x+y=72[/tex]
We know that Jason has three more than four times the amount of money Jeff has. So:
[tex]x=3+4y[/tex]
This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:
[tex](3+4y)+y=72[/tex]
Combine like terms:
[tex]5y+3=72[/tex]
Subtract 3 from both sides:
[tex]5y=69[/tex]
Divide both sides by 5:
[tex]y=69/5=\$13.80[/tex]
So, Jeff has $13.80
We know that Jason has three more than four times the amount of money Jeff has.
Therefore, Jason has:
[tex]x=13.8(4)+3[/tex]
Multiply and add:
[tex]x=\$58.20[/tex]
So, Jason has $58.20 and Jeff has $13.80.
And we're done!

Angles B and D are corresponding angles. This means D = B since corresponding angles are congruent when we have parallel lines.
Then note how D+E = 180 as these two angles form a straight angle.
Replace D with B getting B+E = 180 (this is the substitution property).
Alternatively, you can say that G = E and B+G = 180 to lead to B+E = 180. There are many other routes to take as well.

If the sum of the square of the number and 4 time the number is 21,
what is the number?
Answer:
I think there is a missing “and” there: “If the sum of the square of the number and 4 times the number is 21, what is the number?”
If so, then we have: x² + 4x = 21, or x² + 4x - 21 = 0.
This factors as (x+7)(x-3) = 0, so x = -7 or x = 3.

The angles of a quadrilateral are in the ratio 1:2:3:4. Find the measure of each angle
Answer:
Let us consider that the smallest angle is 'x'.
According to the given ratio, the four angles are:
x2x3x4xNow, for any quadrilateral, the sum of the all four angles should be equal to 360°.
So,
x + 2x + 3x + 4x = 360°
10x = 360°
x = 36°.
Thus, the four angles are:
x = 36° 2x = 2 × 36 = 72° 3x = 3 × 36 = 108° 4x = 4 × 36 = 144°What is the value of x?

What does PIN stand for?
a. Principal Investment Number
b. Permission Initiating Number
c. Percent Increase Number
d. Personal Identification Number
Answer:
D
Step-by-step explanation:
PIN stands for Personal Identification Number. Option d is correct.
What is a Personal Identification Number.?An alphanumeric or numeric string called a personal identification number (PIN) is used to verify a person's identity in a system.
Automated Teller Machines (ATM) for a bank, are the primary use cases for PINs (ATM). PINs are frequently used in place of more complex passwords to unlock mobile devices and authenticate users to applications.
Along with the development of the ATM, PINs were invented in the UK. In 1967, Barclays debuted ATMs as a convenient way for consumers to obtain cash. They also introduced ATM check deposits, which made use of codes printed on checks to help correctly account for such transactions.

Scientific understandings can change as new information is discovered. Which is an example of how scientific understandings have changed? A.People once thought Earth was round. Now they understand that it is flat. B. The Law of Universal Gravitation has not been tested many times and is no longer taught in science. C.The understanding of mountain building and earthquakes changed once people accepted the theory of plate tectonics. D.The inclined plane, which is a simple tool that may have been used by the Egyptians to build the pyramids, now has other applications.
Answer:
E. People once thought animals were individually create by some superior.
But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.
Step-by-step explanation:
Before Charles Darwin several scientists were discussing the hypothesis of a theory of evolution. But it was Darwin whom put together all the information with reliable explanation and correlation between animal specialization and environment accordyinly with time.
He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.

Derrick's Doggie Day Care charges a $12 registration fee plus $5 per hour for pet sitting. Pauline's Pooch Park charges $3 per hour plus an $18 registration fee. Which inequality can be used to find the number of hours, h, for which the cost of Derrick's Doggie Day Care is at most the cost of Pauline's Pooch Park? 12+5h≥3h+18 12 plus 5 h is greater than or equal to 3 h plus 18 5h+12>18+3h 5 h plus 12 is greater than 18 plus 3 h 12+5h<3h+18 12+5h<3h+18 12+5h≤18+3h 12 plus 5 h is less than or equal to 18 plus 3 h
Answer:
[tex]12 + 5h \leq 18 + 3h[/tex]
Step-by-step explanation:
Given
Represent Derrick's with D and Pauline's with P
For D
Registration Fee = $12
Hourly Charges = $5
For P
Registration Fee = $18
Hourly Charges = $3
Required
Represent as an inequality such that D is at most of P
First, we need to represent both as an expression:
For D
[tex]D: 12 + 5h[/tex]
For P:
[tex]P:18 + 3h[/tex]
Since D is at most of P;
This implies that:
[tex]D \leq P[/tex]
So, we have:
[tex]12 + 5h \leq 18 + 3h[/tex]

60 degrees
This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.
So if you add 40 + 90 + x = 180
You get 130 + x = 180
If you subtract 180 - 130
You get 60.

Find x so that the distance between the points (-2,5) and (x,-7) is 13
Distance between both points = 13
We have to find value of x[tex].[/tex]
Distance between two points can be measured by using this formula :
d = √[(x₂ - x₁)² + (y₂ - y₁)²]⭆ d = √[(x₂ - x₁)² + (y₂ - y₁)²]
⭆ 13 = √[(x - (-2))² + (-7 - 5)²]
⭆ 13² = (x + 2)² + (-12)²
⭆ 169 = (x + 2)² + 144
⭆ (x + 2)² = 169 - 144
⭆ (x + 2)² = 25
⭆ x + 2 = 5
⭆ x = 5 - 2

Answer:

Step-by-step explanation:
cc HB buggy CFB
The value of "x" will be "7".
Given:
[tex]m_2 = 6x+8[/tex][tex]m_6=8x-6[/tex]When "m" is parallel, then
→ [tex]m_2=m_6[/tex]
By substituting the values, we get
→ [tex]6x+8=8x-6[/tex]
By adding "6" both sides, we get
→ [tex]6x+8+6=8x-6+6[/tex]
→ [tex]6x+14=8x[/tex]
By subtracting "6x" from both sides, we get
→ [tex]6x+14-6x=8x-6x[/tex]
→ [tex]14=2x[/tex]

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. y=-16x^2+157x+124 y=−16x 2 +157x+124
Answer:
Rocket will hit the ground in 10.55 seconds.
Step-by-step explanation:
Let be [tex]y = -16\cdot x^{2}+157\cdot x +124[/tex], where [tex]x[/tex] and [tex]y[/tex] are time after launch and the height of the rocket, measured in seconds and meters, respectively. To find the time that the rocket will hit the ground, we need to equalize height to zero and solve the resulting expression:
[tex]-16\cdot x^{2}+157\cdot x + 124 = 0[/tex]
The quadratic function can be solved analitically by Quadratic Formula, that is to say:
[tex]x = \frac{-157\pm \sqrt{157^{2}-4\cdot (-16)\cdot (124)}}{2\cdot (-16)}[/tex]
Roots of the polynomial are, respectively:
[tex]x_{1} \approx 10.55\,s[/tex], [tex]x_{2}\approx -0.74\,s[/tex]
Only first root offers to us a reasonable solution. Hence, we conclude that rocket will hit the ground in 10.55 seconds.
