[tex]15 n\\=15(1)\\=15[/tex]
So, Money earned for mowing 1 lawns = 15 dollars
Money earned for mowing 7 lawn:
Put n = 7 in the equation:
[tex]15 n\\=15(7)\\=105[/tex]
So, Money earned for mowing 7 lawns = 105 dollars

The surface area of the prism is 48 units².
Step-by-step explanation:
Remember, a net is simply the outer surface of a 3D shape flattened and spread out as a combination of 2D shapes.
With this info, the rest is relatively easy.
The net shows that there are 4 rectangular sides and 2 square sides. We also know the lengths and widths of all of them.
One rectangle is 5 units long and 2 units wide. One square is 2 units long and 2 units wide.
Let's put this into an equation.
4( 5*2 ) + 2( 2*2)
We are adding the areas of the rectangles and squares.
So, let's simplify that equation.
4(10) + 2(4)
40 + 8

QP = 7
Step-by-step explanation:
Extend PQ to R so that QR=PQ
MQ = QL (known, mid-point)
MPLR is parallelogram (diagonal bisect each other)
MP // RL NP/PR = NE/EL = 1/1 (E mid-point, known)
NP = PR
PQ = QR = 1/2 PR = 1/2 NP
NP = 2 PQ
NP + PQ = 2PQ + PQ = 3 PQ = QN = 21
PQ = 7
PN = 14

Write an equation of the line passing through point P that is perpendicular to the given line P(6, -3), y
Answers
Answer:
Equation of the line is: [tex]x=6[/tex]
Step-by-step explanation:
We know that , the equation of any line parallel to y axis is :
[tex]x=k[/tex] where [tex]k[/tex] ia a constant
And here it is given that the line is passing through the point P(6,-3)
Therefore, it will satisfy the equation [tex]x=k[/tex].
So, substitute [tex](6,-3)[/tex] in equation [tex]x=k[/tex], we get
[tex]k=6[/tex]
Hence the equation of line will be [tex]x=6[/tex]
14 years ago the age of the mother was 4 times the age of her daughter. The presen
age of the mother is 2 times the age of her daughter will be 4 years hence. What
their present ages?
Answers
Answer:
Daughter is 25, mother is 58
Step-by-step explanation:
Let m = age of mother now
Let d = age of daughter now
m - 14 = 4(d - 14)
m = 2(d + 4)
m - 14 = 4d - 56
m = 2d + 8
subtracting them gets
14 = -2d + 64
2d = 50.
d = 25
m = 58

x = 75°
Step-by-step explanation:
From the figure it appears that:
[tex] m\angle B = 36\degree [/tex]
and
[tex] m\angle D = 39\degree [/tex]
x is the measure of the exterior angle of [tex] \triangle BDH[/tex]
Therefore, by exterior angle theorem:
[tex] x = m\angle B+ m\angle D [/tex]
[tex] x = 36\degree+ 39\degree [/tex]
