Answer:
[tex]h=\frac{2A}{b}[/tex]
Step-by-step explanation:
[tex]A=\frac{1}{2}bh[/tex]
Switch sides:
[tex]\frac{1}{2}bh=A[/tex]
Multiply both sides by 2:
[tex]2\cdot \frac{1}{2}bh=2A[/tex]
[tex]bh=2A[/tex]
Divide both sides by b:
[tex]\frac{hb}{b}=\frac{2A}{b}[/tex]
[tex]h=\frac{2A}{b}[/tex]
If the midpoint of the line segment with endpoints (-4, b) and (8, 0) is (2, 1). What is the value of b
Answer:
B=2
Step-by-step explanation:
[tex](\frac{8+x_1}{2} )(\frac{0+y_1}{2})[/tex]
[tex](\frac{8+x_1}{2} )=2[/tex] multiply 2 by 2=4 then write [tex]8+x_1=4[/tex] subtract 8 from both sides 4-8= -4
[tex](\frac{0+y_1}{2} )=1[/tex] multiply 2 by 1=2 then write [tex]0+y_1=2[/tex] subtract 0 from both sides
2-0=2
To check [tex]MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\[/tex]
[tex]MP= (\frac{-4+8}{2} )(\frac{2+0}{2} )[/tex] -4+8=4 2+0=2
[tex]MP= (\frac{4}{2} )(\frac{2}{2} )[/tex] 4/2=2 and 2/2=1 MP=(2,1)
Find the indicated length.
Line WX bisects YZ at point W. Find YZ if WZ=9 5/8
Given :
Line WX bisects YZ at point W.
[tex]WZ=9\dfrac{5}{8}=\dfrac{77}{5}[/tex] .
To Find :
The length of YZ .
Solution :
Since , the point W bisect YZ .
So , it cuts YZ into two equal parts i.e YW and WZ .
Therefore , YW = WZ
Also , YZ = YW+WZ = 2WZ
[tex]YZ = 2\times \dfrac{77}{5}\\\\YZ=\dfrac{154}{5}\\\\YZ=30\dfrac{4}{5}[/tex]
Hence , this is the required solution .

!PLEASE ANSWER FAST ILL GIVE BRAILIEST AWARD! A glider begins its flight 1 1/2 mile above the ground. After 60 minutes, it is 9/10 mile above the ground. Find the change in height of the glider. If it continues to descend at this rate, how long does the entire descent last?
Answer:
The change in height is 6/10 miles per hour and the entire descent will last 150 minutes (2 hours and 30 minutes)
Step-by-step explanation:
The gilder started 1 1/2 miles above the ground, in other words, it started [tex]\frac{15}{10}[/tex] miles above the ground. After 60 minutes it is now [tex]\frac{9}{10}[/tex] miles above the ground.
Therefore, the change in height in one hour is: [tex]\frac{15}{10}-\frac{9}{10}= \frac{6}{10}[/tex] miles.
Now, we know that the glide descends at a rate of 6/10 miles per hour, we can solve the second part of the problem using the rule of three (or proportions)
If it takes it 60 minutes to descend 6/10 miles, how long it will take it to descend 15/10 miles?
60 minutes --- 6/10= .6
x minutes ---- 15/10= 1.5
Therefore [tex]x=\frac{60(1.5)}{.6} =\frac{90}{0.6} =150[/tex] minutes
Thus, the entire descent will last 150 minutes.

24 = b -3 Just add 3 to both sides
+3 +3
b = 27
Answer:
b=27
Step-by-step explanation:
Let's solve your equation step-by-step.
24=b−3
Step 1: Flip the equation.
b−3=24

Three saucepans hold 500ml,1litre and 2.5litres respectively.Write the ratio of their capacities in its lowest terms
Answer:
1 : 2 : 5
Step-by-step explanation:
Each quantity must be expressed in the same units of measure, thus
1 litre = 100 ml and 2.5 litres = 2500 ml , then
500 : 1000 : 2500 ← divide each part by 500
= 1 : 2 : 5 ← in simplest form

an atom has an atomic number of 12 and a mass number of 25.how many neutrons does the atom have?
Answer:
The atomic number is the number of protons (12) and the mass number is the number of neutrons and protons combined. So you'd subtract 12 from 25 (25-12=) and that'd get you 13 as your answer. If you need to find the number of electrons, it'll be the same as the number of protons unless it has a certain charge and if it does, if it's positive it has more protons (+) than electrons (-), if it is negative it has more electrons (- negatively charged) than protons (+ positively charged)

What is the value of x in the equation 2/3x + 3 = 7
Answer:
6
Step-by-step explanation:
2/3x=4
then 4/ 2/3 (you can just input this in a calculator)
it equals 6!
Answer:
x=6
Step-by-step explanation:
2/3x + 3 = 7
subtract 3 from both sides to get
2/3x = 4
divide 2/3x by 2/3 to isolate the variable
2/3x ÷ 2/3 = 4
what you do to one side you do to the other, so divide 4 by 2/3 as well, then you get
2/3x ÷ 2/3 is x
4 ÷ 2/3 is 12/2 which is equal to 6.
x=6

If S (3,-4) is translated 5 units left and 3 units up, what is the ordered pair of S?
Answer:
(-2,-1)
Step-by-step explanation:
3-5=-2
-4+3=-1
The coordinate of the point S if the point is translated 5 units left and 3 units up are (-2,-1). The correct option is A.
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
Given the coordinate (3,-4) of the point S. Now, if the point is translated 5 units left and 3 units up, then the new coordinates of S are,
(3,-4) → (3-5 , -4+3) = (-2, -1)
Hence, the coordinate of the point S if the point is translated 5 units left and 3 units up are (-2,-1).

The length of a rectangle is 7 inches more than its width. The perimeter of
this rectangle is 78 inches. Find the length of this rectangle.
First known equation is:
2L + 2W = 46
Second equation is:
L = W +7
Put the variable L of the second equation in the first equation.
2(W+7) + 2W = 46
2W +14 +2W = 46
4W = 32
W=8
Then resolve L using any of the above initial equations
L = 8 + 7 = 15
Verify: 2L +2W = 46
2(15) + 2(8) = 30 + 16 = 46 = perimeter
Step-by-step explanation:
Let the length = 7x
Let the breadth = x
As we know that
perimeter of rectangle =2(l+b)
Also perimeter here = 78 inches
Acc. to question
2(l+b) = 78 inches
[tex]2(7x + x) = 78[/tex]
[tex]16x = 78[/tex]
[tex]x = \frac{78}{16} [/tex]
[tex]x = 4.8[/tex]
so bredth = 4.8 approx
length = 7*4.5 =31.5 approx
