Answer:
B. 55
Step-by-step explanation:
The angle measurements on the top are the same as the bottom, so we know the angle next to (x+70) is 55. You then subtract 55 from 180 and you are left with 125. Then you have to subtract 70 to find x, which gives you 55. Therefore, x=55
what’s 2/3 times 1/8????
Answer:
0.0833333333, or 1/12
Step-by-step explanation:
step 2 Multiply both numerators
= 2 x 1
= 2
step 3 Multiply both denominators
= 3 x 8
= 24
step 4 Use above values of step 2 & 3, and rewrite as below
= 2/24
Thus, 2/24 is equivalent fraction for 2/3 times of 1/8, and its simplified term is 1/12.

Step-by-step explanation:0.1
Given (x – 1)2 = 50, select the values of x.
x = –49
x = 51
x= 1 + 5 (2
x= 1 - 5 (2
x= 1 + 5 √2
x= 1 - 5 √2
The values of x in the expression are x = 1 + √51 and x = 1 – √51.
We have,
Expanding the left side of the equation, we get:
(x – 1)2 = x2 – 2x + 1
So, we have:
x2 – 2x + 1 = 50
Subtracting 50 from both sides, we get:
x2 – 2x – 49 = 0
Now, we can use the quadratic formula to solve for x:
x = [2 ± √(22 – 4(1)(–49))] / (2)
x = [2 ± √(204)] / (2)
x = [2 ± 2√51] / (2)
x = 1 ± √51
Therefore,
The values of x are x = 1 + √51 and x = 1 – √51.

The angle between 0 and 2π in radians that is coterminal with the angel 19π/4 in radians is what?
Answer:
29/24π
Step-by-step explanation:
To get coterminal angles, you simply have to add or subtract 2π
In this problem, we are looking for a coterminal angle that is between
0 and 2π, so we will add 2π to −19/24π.
−19/24π+2π
=
−19/24π+48/24π
=
29/24π
29/24π
is the answer to the question.
[tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).
What is coterminal angle?
Coterminal angles are the angles that have the same initial side and share the terminal sides.
How to find the coterminal angles?To find the coterminal angle of an angle, we just add or subtract multiples of 360 degrees from the given angles.
According to the given question.
We have
Angle = [tex]\frac{19\pi }{4}[/tex]
Since, the coterminal angle is to be between 0 and 2π.
Therefore, we subtract 2π from [tex]\frac{19\pi }{4}[/tex]to get coterminal angle.
⇒ [tex]\frac{19\pi }{4} -2\pi[/tex] [tex]= \frac{19\pi -8\pi }{4} =\frac{11\pi }{4}[/tex]
Hence, [tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).

A student did an experiment to determine the number of letters recognized on an eye chart to see if it was affected by distance. What is the independent and dependent variable in this experiment?
Answer:
Independent variable: distance
Dependent variable: number of letters recognized on an eye chart
Step-by-step explanation:
Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.
Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.
Since the hypothesis is that the distance affects the number of letters recognized,
the distance causes a change in the number of letters recognized not the other way around.
Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

Answer:x=30
Step-by-step explanation:
So first you have to find x so add all your sides together:
Equation: 45+2x+0.5x+x=150
Combine like terms: 45+3.5x=150
Subtract 45 from -45 -45
both sides: 3.5x=105
Then divide by 3.5: x=30
Now that you have your x substitute it in:
2(30)=60
0.5(30)=15
and the last one is x=30
And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.

Step-by-step explanation:
3−2(x+1)=2x−7
3+(−2)(x)+(−2)(1)=2x+−7(Distribute)
3+−2x+−2=2x+−7
(−2x)+(3+−2)=2x−7(Combine Like Terms)
−2x+1=2x−7
−2x+1=2x−7
Step 2: Subtract 2x from both sides.
−2x+1−2x=2x−7−2x
−4x+1=−7
Step 3: Subtract 1 from both sides.
−4x+1−1=−7−1
−4x=−8
Step 4: Divide both sides by -4.

Jared wants to make a scale drawing of his bedroom. His bedroom is a rectangle with a length of 600 cm and width of 400 cm. He decided on a scale of 1 to 50. 1.Jared's bedroom door is 60 cm wide. How wide should the door be on the scale drawing? Explain how you know. 2.Jared's bed measures 4 cm by 5 cm on the scale drawing. What are the actual measurements of his bed?
Answer:
(1) 1.2 cm
(2) 200 cm by 250 cm
Step-by-step explanation:
The scaled dimention = (Actual dimension) x (scale factor) ...(i)
The given scale factor =1/50
(1) The actual width of the bedroom door= 60 cm.
So, from equation (i),
the width of the door on the scale drawing= 60 x (1/50)=1.2 cm
(2) The scaled dimension of the bed is 4 cm by 5cm.
So, the scaled width of the bed = 4cm and
the scaled length of the bed = 5cm.
So, from equation (i),
4 cm = (Actual width) x (1/50)
So, Actual width = 50 x 4 cm = 200 cm.
And, 4 cm = (Actual length) x (1/50)
So, Actual width = 50 x 5 cm = 250 cm.
=Hence, the actual measurements of his bed is 200 cm by 250 cm.
