Answer:
x = -2 and x = 7
Step-by-step explanation:
Since this is a multiplication, you can divide the equation into two parts to find what x values would make the equation equals to 0 because when you only need one multiple to equal 0 regardless of the value of the other multiple to make the equation equal to 0.
(x + 2) = 0 = > x = -2
(x - 7) = 0 = > x = 7
Shapes S and T are similar.
The area of S is 22 cm2. The area of T is 269.5 cm2.
Find the length of side x.
Answer:
x = 6 cm
Step-by-step explanation:
Area of T = 269.5 cm²
Area of S = 22 cm²
Length of side of T = 21 cm
Length of side of S = x
Area of T : Area of S = square of length side of T : square of length side of S (x)
Thus:
269.5/22 = 21²/x²
Cross multiply
x² × 269.5 = 21² × 22
x² × 269.5 = 9,702
Divide both sides by 269.5
x² = 9,702/269.5
x² = 36
x = √36
x = 6 cm

Sally can paint a room in 3 hours while it takes Steve 9 hours to paint the same room. How long would it take them to paint the room if worked together?
Answer:
[tex]2 \frac{1}{4}[/tex]
Step-by-step explanation:
Okay, so- The first thing I did was see how much they got done per hour. Like this:
Sally ⇒
3 hours = 1 room
1 hour = 1/3 of the room
Steve ⇒
9 hours = 1 room
1 hour = 1/9 of the room
Sally + Steve ⇒
1 hour = 1/3 + 1/9 = 3/9 + 1/9 = 4/9
So, they get 4/9 of a room done in 1 hour.
Number of hours needed ⇒
1 ÷ 4/9 = 2 1/4
Answer: They need 2 1/4 hours to paint the room.

find the sum to m
Answer:
m = 3/100
Step-by-step explanation:
211m + 16 = 4 + 611m
211m - 611m = 4 - 16
-400m = -12
m = -12/-400
m = 3/100

Answer:
x = 36
1 = 42
2 = 108
Step-by-step explanation:
2x + x + 72 = 180
3x + 72 = 180
-72 -72
3x = 108
divide by 3
x = 36
_______________________
1 = 2x
1 = 2(36)
1 = 42
_______________________
2 = x + 72
2 = 36 + 72
2 = 108
Hope this helped! Have a nice day! Plz mark as brainliest!!!

What causes all wind?
differences in gravity
difference in oxygen
differences in air pressure
differences in the thermosphere
2. What causes differences in air pressure?
even heating of the Earth
even cooling of the earth
uneven heating of the earth
global warming
3. The Sun warms the atmosphere and drives convection currents because
warm air is more dense than cooler air.
warm air has more pressure than cooler air.
warm air is less dense than cooler air.
warm air has a higher dew point than cooler air.
4. Land and water absorb and release the sun’s heat in different ways. One result of this is a sea breeze. Which statement is true of sea breezes?
They happen during the day and blow toward the land.
.They happen during the day and blow toward the water.
They happen during the evening and blow toward the land.
They happen during the evening and blow toward the water.
5. Why do land breezes occur at night?
Land cools off slower than water, so the air above water is cooler.
Water cools off faster than land, so the air above land is warmer
Land heats up slower than water, so the air stays cooler during the day.
Water cools off slower than land, so the air above water is warmer.
6. Why does the Earth experience unequal heating?
The oceans are not equally distributed around the Earth.
The Earth's revolution brings it closer to the Sun at certain points during the year.
The Earth's axis is tilted causing sunlight to be distributed unequally.
The atmosphere is not equally distributed around the Earth.
7. The Coriolis Effect is caused by the rotation of earth. What impact does this have on global winds?
Global winds are much stronger due to the Coriolis Effect
Global winds are curved clockwise in the northern hemisphere and counterclockwise in the Southern Hemisphere due to the Coriolis Effect
Global winds follow straight paths from pole to pole due to the Coriolis Effect
Global winds are not impacted by the Coriolis Effect
8. What is the general pattern of winds at the equator?
Winds are generally strong because the equator is a region of mostly low air pressure
Winds are generally weak because the equator is a region of mostly low air pressure
Winds are generally strong because the equator is a region of mostly high air pressure
Winds are generally weak because the equator is a region of mostly high air pressure
9. What type of winds blow constantly, predictably, and over long distances?
land breezes
mountain breezes
global winds
lake breezes
10. Which statement correctly defines wind?
Wind is the movement of air from areas of high pressure to areas of low pressure.
Wind is the movement of air from areas of low pressure to areas of high pressure
Wind is the movement of air pushed around and bouncing off Earth's surface.

if the circumference of a circle is 10pie inches, which is the area?
Answer:
A = 78.54 in^2
Step-by-step explanation:
Circumference of the circle = 10 pie inches
Determine the area of the circle.
Formula for the area of the circle:
A = pi r^2
Formula for the circumference of the circle:
C = 2 pi r
Solution:
Solve first for the radius of the circle by using the circumference of the circle.
10 pi in= 2 pi r
Divide 2 pi on both sides of the equation in order to determine the value of r.
10 pi in/2 pi = 2 pi r/ 2 pi
r = 5 inches
Substitute the value of r to the formula for the area.
A = pi (5 inches)^2
A = 25 pi in^2
A = 78.54 in^2
Final answer :A = 78.54 in^2
