Solve -4=12p+10/2 can someone please help??

1 answer:

3 0

So first you would divide the 10 by 2
-4=12p+5

Then you subtract the five from both sides to try to isolate the variable p
-4=12p+5
-5 -5
You then divide both sides by 12 to solve for p and simplify
-9=12p
(-9/12)=(12p/12)
-3/4=p

X and w is 105 degrees and y and z are 86 degrees. since line L is a straight line it would have to add up to 180 and same with line M

Joe opened a book store. On the first three days he sold 15, 18, and 16 books (he initially hoped he sell 17 books everyday). Ho

$\frac{15 + 18 + 16 + x}{4} = 17 \\ \frac{49 + x}{4} = 17 \\ 49 + x = 17 \times4 \\ 49 + x = 68 \\ x = 68 - 49 \\ x = 19$

2. A square-based tent has the cross-sectional

ollegr [7]

(a) Length of the height is 2.732 m

(b) Length of the base is 5.466 m

<u>Explanation:</u>

An image is attached for reference.

(a)

In ΔAOB,

$sin 30^o = \frac{AO}{AB} \\\\0.5 = \frac{AO}{2} \\\\AO = 1 m$

In ΔBGD,

$sin 60^o = \frac{BG}{BD} \\\\0.866 = \frac{BG}{2} \\\\BG = 1.732 m$

According to the figure, BG = OE = 1.732 m

Height of the tent, AE = AO + OE

= 1 m + 1.732 m

= 2.732 m

(b)

DF = ?

In ΔAOB,

$tan 30^o = \frac{AO}{OB} \\\\0.577 = \frac{1}{OB} \\\\OB = 1.733 m\\\\\\$

According to the figure, OB = GE = 1.733 m

In ΔBGD,

$tan 60^o = \frac{BG}{DG} \\\\1.732 = \frac{1.732}{DG}\\ \\DG = 1m$

According to the figure, DE = DG + GE

DE = 1 m + 1.733 m

DE = 2.733 m

Length of the base, DF = 2 X DE

DF = 2 X 2.733 m

DF = 5.466 m

I need help on this question please

stepladder [879]

Answer:

The question does not have value of height (in the image)

the barn in shape of a cuboid with a half cylinder.

volume of barn = volume of cuboid + volume of cylinder/2

$\text{Volume}_{barn}=lbh+\frac{\pi r^2 l}{2}$

here,

$2r = b$

b=6 m

l=10 m

so, 2r=6. thus, r=3,

$\text{Volume}_{barn}=lbh+\frac{\pi r^2 l}{2} \\ \text{Volume}_{barn}= 60\timesh+\pi \times9 \times 5$

which approximately,

141.3+60h

for storing all of the hay

141.3+60h≥600

h≥7.644

so..

check if h is less than 7.644, he would not be able to store all of the barn.

mark brainliest please.
