Step-by-step explanation:
Given: 100 lbs on Earth is 16.6 lbs on the moon.
a. The independent variable is weight. The gravity of the Moon and the gravity of the Earth are constant. Weight can change, but gravity is a constant.
b. An equation that relates the weight of someone on the Moon who travels to the Earth:
100 / 16.6 = 6.02. Take the Moon weight and multiply by 6.02:
Moon Weight * 6.02 = Earth Weight.
Proof:
16.6 * 6.024 = 99.99 - approximately 100 lbs Earth weight.
c. A 185 lb astronaut on Earth would weigh:
16.6 / 100 = .166. Take the Earth weight and multiply by .166:
185 * .166 = 30 lbs on the Moon.
d. A person who weighs 50 lbs on the Moon:
50 * 6.024 = 301.2 lbs on Earth.

The Fernandez family has a square driveway with an area of 210.25 m2. Find the perimeter of the driveway. Round your answer to the nearest foot. There are approximately 3.3 ft in 1 meter. What’s the answer?
Answer:
191 ft
Step-by-step explanation:
Mathematically, the area of a square is the square of the length of its side
so if the side is l, the area will be l^2
we need the length before we get the perimeter
Thus;
l^2 = 210.25
l = √210.25
l = 14.5 m
We now need to get the perimeter of the drive way
The perimeter of the driveway will be 4 * l
= 4 * 14.5 = 58 m
we now convert this to ft
From the question;
3.3 ft = 1 m
x ft = 58 m
x = 58 * 3.3
x = 191.4 ft
To the nearest foot, this is 191 ft
Given: wzx and yzx are right triangles, wx = yx. Prove wxz ~= yx .....plz answer will give brainlyest!!
Answer:
The answer is below
Step-by-step explanation:
From the question,
Statement Reason
ΔWZX and ΔYZX are Given
right angled triangles
WX = YX Given
XZ ≅ XZ Reflexive property. The reflexive
property of congruence states that
any shape is congruent to itself.
∠XZW = ∠XZY Definition of right angle.
∠XWZ = ∠XYZ Definition of isosceles triangle.
Triangle XYW forms a right angled
triangle since YX = WX
∠XWZ + ∠WXZ + ∠XZW = 180° Sum of angles in triangle WZX
∠XZY + ∠XYZ + ∠YXZ = 180° Sum of angles in triangle YZX
∠XWZ + ∠WXZ + ∠XZW = Substitution
∠XZY + ∠XYZ + ∠YXZ
∠XYZ + ∠WXZ + ∠XZY = Substitution
∠XZY + ∠XYZ + ∠YXZ
∠WXZ = ∠YXZ Simplification
Write the equation of the line in slope-intercept form.
Answer: y=-3/4x
Step-by-step explanation:
The slope intercept form is when you use the equation y=mx+b (m is the slope and b is the y-intercept). First, let's find the y intercept. The y intercept is what y would be if x is 0. here, you can see that this particular line passes through the origin. So, the y-intercept is zero because when x passes through zero, y is also zero. Next, let's find the slope. The formula for slope is change in y/change in x. Let's randomly choose 2 points off this line. To make this a thousand times easier for us, let's choose the points (-4, 3) and (4, -3). Now, to find the change in y, let's find the difference between the 2 y coordinates we have chosen. To do this we just need to do -3-3, which gives us -6. Now let's find the change in x. To do this we will do the same thing we did to find the change in y but this time we'll use the x coordinates. We will do 4-(-4), which simplifies to 8. Now, we're almost done. Just divide the change in y by the change in x. You will get -6/8. This can be simplified to -3/4. So now we know our slope is -3/4 and our y-intercept is 0. Let's insert them into the equation. y=-3/4x+0. We know that we can just get rid of that 0 because 0 literally means nothing. So our final answer is y=-3/4x. Hope this helps!

PLEASE HELP !!! i need to know the surface area
Answer:
244 ft²
Step-by-step explanation:
Rectangle Base Area: 6•4=24
Rectangle Side Area: 8•10=80; 80•2(sides) = 160
Triangle Sides Area: (10•6=60); 60/2(area of triangle) = 30; 30•2(sides)=60*
*Technically can skip the divide by two and then multiply by two, since they cancel out*
(Area of Triangle Formula= 1/2bh)
Add areas together: 24+160+60= 244 ft²

Angle BAC and Angle FAC are examples of what type of angle pair? (1 point)
Angle BCE and Angle DCA are examples of what type of angle pair? (1 point)
Answer:
Answer:
Try this option, note: only calculation is performed, the last two question are missed.
Step-by-step explanation:
to calculate 'x':
the rule: m∠BAC+m∠ABC+m∠BCA=180°; if to substitute m∠BAC=4x+10,m∠ABC=12x-6,and m∠BCA=3x+5, then 4x+10+12x-6+3x+5=180°; ⇔ x=9.
to calculate m∠BAC; m∠ABC; m∠BCA:
m∠BAC=4x+10; ⇒ m∠BAC=36+10=46°;
m∠ABC=12x-6; ⇒ m∠ABC=108-6=102°;
and m∠BCA=3x+5; ⇒ m∠BCA=27+5=32°.
to calculate the angle 1 and 2:
the fule is: m∠1+m∠BAC=180° and m∠2+m∠ABC=180°.
Then m∠1=180-m∠BAC=180-46=134°;
m∠2=180-m∠ABC=180-102=78°.

-21 = -9 + 2/3b
Final Answer: [tex]b = -18[/tex]
Steps/Reasons/Explanation:
Question: Solve [tex]-21 = -9 + \frac{2}{3}b[/tex].
Step 1: Simplify [tex]\frac{2}{3}b[/tex] to [tex]\frac{2b}{3}[/tex].
[tex]-21 = -9 + \frac{2b}{3}[/tex]
Step 2: Regroup terms.
[tex]-21 = \frac{2b}{3} - 9[/tex]
Step 3: Add [tex]9[/tex] to both sides.
[tex]-21 + 9 = \frac{2b}{3}[/tex]
Step 4: Simplify [tex]-21 + 9[/tex] to [tex]-12[/tex].
[tex]-12 = \frac{2b}{3}[/tex]
Step 5: Multiply both sides by [tex]3[/tex].
[tex]-12[/tex] × [tex]3 = 2b[/tex]
Step 6: Simplify [tex]-12[/tex] × [tex]3[/tex] to [tex]-36[/tex].
[tex]-36 = 2b[/tex]
Step 7: Divide both sides by [tex]2[/tex].
[tex]-\frac{36}{2} = b[/tex]
Step 8: Simplify [tex]-\frac{36}{2}[/tex] to [tex]-18[/tex].
[tex]-18 = b[/tex]
Step 9: Switch sides.
[tex]b = -18[/tex]

Step-by-step explanation:
the answer is d 17 miles/gallon
Answer: B) 11 miles/gallon
This can be written as 11 miles per gallon and shortened to 11 mpg
==========================================================
Explanation:
The odometer reads 143,986 miles when the gas tank is full.
Then it reads 144,261 miles when the gas tank is empty (when all the gas is used up).
This is a difference of 144,261-143,986 = 275 miles.
The truck's gas tank has a capacity of 25 gallons, so this means
(275 miles)/(25 gallons) = 11 miles/gallon = 11 miles per gallon
is the gas mileage of the truck.
----------------
Put another way:
We know the truck traveled 275 miles on 25 gallons. We can form this ratio
275 miles : 25 gallons
Divide both parts by 25 to get the "25 gallons" to turn into "1 gallon"
275 miles : 25 gallons
275/25 miles : 25/25 gallons
11 miles : 1 gallon
Therefore, each gallon of gas will let the truck drive 11 miles. So the truck gets 11 mpg.

SHOW YOUR WORK
Answer:
y = -5x + 29
Step-by-step explanation:
Slope-Intercept Form of the Line
Given a line of slope m and y-intercept b, the equation of the line can be written as:
y = mx + b
The slope can be calculated by using the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x1,y1) and (x2,y2) are the points through which the line passes.
We are given the points (5,4) and (6,-1), thus:
[tex]\displaystyle m=\frac{-1-4}{6-5}=\frac{-5}{1}=-5[/tex]
Now we use one of the points to find the value of b, for example (5,4):
4 = -5(5) + b
b = 25+4 = 29
Thus, the equation of the line is:
y = -5x + 29

A farmer has 3/4 acre of land. He will use all the land and plant different vegetables in 1/16 -acre sections. How many sections of vegetables will the farmer have?
Answer: 12 sections of 1/16 acre
Step-by-step explanation:
We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.
This is equal to the quotient between 3/4 and 1/16
Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:
(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)
The quotient we want to solve is:
(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12
Then you can have 12 sections of 1/16 acre
Answer:
