Answer:
m1=m2 = 111 degrees
Step-by-step explanation:
1. construct a line between angles 1 and 2
//now we have 2 triangles. They are both isoscles triangles.
3. m(base angles in 90 triangle) = (180-90)/2 = 45 degrees. (base angle th.)
4. m(base angles in 48 triangle) = (180-48)/2 = 66degrees. (base angle th.)
5. m1 = 66+ 45 = 111 degrees. (algebra)
6. m2=m1 = 66+45 =111 degrees (algebra)
check:
sum of all angles has to add up to 360 degrees.
48 + 90+ 111+111=360
360=360

0.2(3k+1)=-0.4-(-0.2-0.1K)
Answers
Answer:
k=−0.8
Step-by-step explanation:
Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)
Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)
(0.2)(3k) + (0.2)(1) = 0.6k + 0.2
(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k
New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k
Now we can combine like terms on the right side. (-0.4 and 0.2)
0.6k + 0.2 = 0.1k - 0.2
Now to get rid of k on one side, we can subtract 0.1k from the right side.
(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2
0.5k + 0.2 = -0.2
Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.
0.5k + (0.2 - 0.2) = (-0.2 - 0.2)
0.5k = -0.4
To get k by itself, we must divide both sides by 0.5.
(0.5k / 0.5) = (-0.4 / 0.5)
k = -0.8

Solve 2x + 20 = 6x – 12*
Answers
Answer:
x = 8
Step-by-step explanation:
Given
2x + 20 = 6x - 12 ( subtract 2x from both sides )
20 = 4x - 12 ( add 12 to both sides )
32 = 4x ( divide both sides by 4 )
8 = x
=> 2x + 20 = 6x - 12
=> 20 + 12 = 6x - 2x
=> 32 = 4x
=> x =32/4
=> x = 8Isaiah earns $60 per week mowing lawns in the summer and shoveling driveways in the winter. He invested $220 in equipment. How long will it take him to earn $860? Find the equation and solve.
Answers
Answer:
18 weeks
Step-by-step explanation:
Create an equation where x is the number of weeks he works
60x - 220 will represent his profit, since he gets $60 a week but spent $220 in equipment.
Set this equal to 860, then solve for x, to find when he will earn $860
60x - 220 = 860
60x = 1080
x = 18
So, it will take him 18 weeks to earn $860

Answer:
25. 50 percent of 50 is 25 divided by 2.

step1:Our output value is .50.
step2:we represent the unknown value with x
step3: from step1 above,.50=100%
step4: similarly,x=50%
step5: This results in a pair of simple equation:
.50=100%(1)
x=50%(2)
step6:by dividing equation 1 by equation 2 and noting that both the RHS(right hand side)of both equations have the same unite(%);we have
.50. 100%
____. = ____
x. 50%
step7: again,the reciprocal of both sides gives

f(x)= 2x +6 , vertical shrink by a factor of 1/2
Answers
Answer:
g(x) = x+3.
Step-by-step explanation:
i hope this helps :D
When a function is shrunk vertically, the function has undergone a form of transformation.
The resulting function when [tex]f(x) = 2x + 6[/tex] vertically shrink by 1/2 is [tex]f'(x) = x + 3[/tex]
Given that:
[tex]f(x) = 2x + 6[/tex]
[tex]k = \frac 12[/tex] --- shrink factor
When a function is shrunk vertically, the rule of transformation is:
[tex](x,y) \to (x,ky)[/tex]
So, we have:
[tex]f'(x) = k f(x)[/tex]
The new function becomes
[tex]f'(x) = \frac 12 \times (2x + 6)[/tex]
[tex]f'(x) = x + 3[/tex]
Hence, when [tex]f(x) = 2x + 6[/tex] is vertically shrunk by 1/2, the new function is [tex]f'(x) = x + 3[/tex]

Sasha uses 6.1 pints of white paint and blue paint to paint her bedroom walls. 2/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer: 3.66 pints of blue paint.
Step-by-step explanation:
She used 2/5 of the total number of pints to paint white.
That number in pints is:
= 2/5 * 6.1
= 2.44 pints of white
The number of pints used to paint blue is therefore:
= 6.1 - 2.44
= 3.66 pints of blue paint.
