Answer:
vhvffvvvchbbjkkbc
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]
[tex]x = \frac{14}{2}[/tex]
[tex]= 7[/tex]

Scott is revising for a test that has 20
marks. He thinks the length of time he spends revising
for a test is directly proportional to the number of marks he gets. If he revises for
30 minutes he gets 12 marks. Assuming Scott is correct
How long would he need to revise to get
18
marks?
Answer:
It would take 45 minutes to get 18 marks
Step-by-step explanation:
30 ÷ 12 = 2.5
2.5 x 18 = 45

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.

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
⭆ x = 3

Step-by-step explanation:
3 inches= 50 miles
1 inch = 50/3 miles
7 inches = 50/3 × 7 miles
= 116.66666667 miles
The diameter of a human red blood cell is 0.000009 m. The diameter of a cold virus is 0.00000003 m Approximately how many times as large is the diameter of a red blood cell as the diameter of a cold virus? A :3⋅10^-14 B:3⋅10 ^−2 C :3⋅10 ^1 D ;3⋅10 ^2
Answer:
D. 3*10^2
Step-by-step explanation:
Given the diameter of human red blood cell = 0.000009 m
diameter of a cold virus = 0.00000003 m
To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;
diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m
= 9*10^-6/3*10^-8
= 9/3 * 10^-6-(-8)
= 3 * 10^(-6+8)
= 3*10^2
Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus
Answer:
D. 3*10^2

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.

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°Given f(x) = 10(3 - 2x), what is the value of f(-9)?
Answer: 210
Step-by-step explanation:
f(x) = 10(3 - 2x)
f(-9) = 10(3 - 2(-9)
f(-9) = 10(3+18)
f(-9) = 10(21)
f(-9) = 210

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]
Which expression will have the same value as 3(4 x + 9) ‒ 6 x for all values of x?
