The complement of angle B is 90-x.

Now, 7 times the complement of angle B is 7*(90-x).

The supplement of angle B is 180-x.

Twice the supplement of angle B is 2*(180-x).

Here is the algebra:

7*(90-x)-2*(180-x)=220

630-7x-360+2x=220

-5x= 220+360-630

-5x=-50

x= -50/-5

x=10 degrees

Answer: 10 degrees.

Answer:

197

Step-by-step explanation:

You have 6 sides of this object. So we will calculate six surface areas.

P1=5x5=25 ( on the top)

P2=9x5=45 ( on the bottom)

P3= 5x5= 25 (left side)

P4=6,4x5=32 (rightside)

P5= (9+5)x5/2=70/2=35 ( front trapeze)

P6=P5=35 ( behided trapeze)

P= p1+p2+p3+p4+p5+p6=

25+45+25+32+35+35 =197

When a survey was conducted among 100 students to find their favorite pizza topping, 45 students voted for pepperoni, 25 for mus

Answer:

The central angle for the cheese sector would be 108 degrees.

Step-by-step explanation:

We know that a pi chart takes the form of a circle so the total angle measure is 360 degrees.

Now we want to find out what ratio of the pie chart that cheese takes up and apply it to the total degree measure.

30 of 100 students voted for cheese:

so the ratio would be 30/100 or 3/10

Now apply that to the total angle measure:

3/10*360 degrees= 108 degrees.

Which equation is parallel to the line LaTeX: y=\frac{1}{2}x+3y = 1 2 x + 3and passes through the point (10, -5)?

sukhopar [10]

Answer:

$Equation\ of\ line:\ y=\frac{1}{2}x-10$

Step-by-step explanation:

$Let\ the\ required\ equation\ is\ y=mx+c\\\\where\ m\ is\ the\ slope\ of\ the\ equation\ and\ c\ is\ y-intercept\\\\It\ is\ parallel\ to\ the\ equation\ y=\frac{1}{2}x+3\\\\Hence\ slope\ of\ these\ two\ lines\ will\ be\ same.\\\\Slope\ of\ y=\frac{1}{2}x+3\ is\ \frac{1}{2}\\\\Hence\ slope\ of\ y=mx+c\ is\ \frac{1}{2}\Rightarrow m=\frac{1}{2}\\\\Equation:y=\frac{1}{2}x+c\\\\Line\ passes\ through\ (10,-5).\ Hence\ this\ point\ satisfies\ the\ equation\ of\ line.\\\\-5=\frac{1}{2}\times 10+c$

$-5=-5+c\\\\c=-10$

$Equation\ of\ line:\ y=\frac{1}{2}x-10$
