What is the slope of a line that is perpendicular to the line represented by the equation 3x + 4y = 12?
Vikentia [17]

Answer:

-3/4

Step-by-step explanation:

3x+4y=12

get into y=mx+b form first (m is the slope, b is the intercept)

So, 4y=12-3x

Then y=(12/4)-(3/4)*x

So your m is -3/4

Since you said it must be parallel the slope is the same to ensure they never touch

It took 12 men 5 hours to build an airstrip. Working at the same rate, how many additional men could have been hired in order fo
motikmotik

Answer:

B

Step-by-step explanation:

hello the question is if it took 12 men 5 hours to build an age is working at the same rate how many additional men could have been hired in order for the job to have taken 1 hour less ok so we have to find that how many extra may be required to complete the job for a strip 1 hour less than five hours that is 4 hours ok bye have to complete the airstrip in 4 hours and they have to find that how many experiment we have to required for that we will assume that let extra number of number of extra man bhi X show the number of men when we are finishing in it in 4 hours would be 12 + X ok

would be the number of men now and time required would be equal to 1 hour less than 5 hours that is 4 hours ok no from the given data we can say that one cares if strip x 12 men and fibres ok so all vacancy job correct so vacancy job per man are would be 1 divided by 12 in 25 this is the job or the amount of a strip that is completed when

one man works for one hour ok so this is the amount of the job that is done for men power and we have we have this number of men that are not want working and the number of hours that their working for so for one job we will need for one job would be best job per man per hour into number of men into number of hour ok and we have 1 equal to number of Doberman per Rs 1 by 2 11 25 and number of men we have already know that 12 + 6 is the number of men that we will require 12 + X number

forces were less than 5 that is 44 4312 so it would give us 12 + X / 3515 1 to 15 of this site it would give us 12 + X equal to 15 which implies X is equals to 15 - 12 and X is equals to 3 significant required 3 more men to complete the job in Porus dancer is 3 which is given is be in the question make you

a flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 10 feet mor
Amiraneli [1.4K]

Answer:

42,84,61

Step-by-step explanation:

let the shortest side be x

x + 2x + x + 19 = 187

therefore, 4x + 19 = 187

therefore, 4x = 168

x = 42

So the shortest side is 42

Longest is 84

and the third side is 61

In ΔABC, m∠ACB = 90°, CD ⊥ AB and m∠ACD = 45°. Find AC, if CD = 6 sqrt 3
Alla [95]

Answer:

6\sqrt{6}\ un.

Step-by-step explanation:

Consider right triangle ABC with right angle ACB. If m∠ACD = 45°, then

m∠BCD=m∠ACB-m∠ACD=90°-45°=45°.

Since  CD ⊥ AB, then

m∠CDA=m∠CDB=90°.

Thus, triangles ACD and BCD are right triangles with right angles ADC and BDC. In these triangles:

m∠CAD=90°-m∠ACD=90°-45°=45°;

m∠CBD=90°-m∠BCD=90°-45°=45°.

Thus, triangles ACD and BCD are isosceles right triangles with

CD=AD=BD=6\sqrt{3}\ un.

By the Pythagorean theorem,

AC^2=CD^2+AD^2,\\ \\AC^2=(6\sqrt{3})^2+(6\sqrt{3})^2,\\ \\AC^2=216,\\ \\AC=6\sqrt{6}\ un.

6(-6+x)=76-2x can i get some help please
NNADVOKAT [17]

Answer:

x=14

Step-by-step explanation:

6(-6+x)=76-2x

Distribute

-36 +6x = 76 -2x

Add 2x to each side

-36+6x+2x = 76-2x+2x

-36 +8x = 76

Add 36 to each side

-36+36 +8x = 76+36

8x = 112

Divide by 8

8x/8 = 112/8

x=14
