2. The sum of the measures of angle X and angle Yis 90. If the measure of angle Xis 30 less than twice the

Slav-nsk [51]

Answer:

50 degrees

Step-by-step explanation:

x + y = 90

x = 2y - 30

2y - 30 + y = 90

3y - 30 = 90

3y = 90 + 30

3y = 120

y = 120/3

y = 40

x = 2y - 30

x = 2(40) - 30

x = 80 - 30

x = 50 <====== angle x

Please help! Does anyone know how to work this surface area question out???

Alik [6]

Surface area of a cylinder=(2xxradiusxheight)+(xradius^2x2)

Radius=Diameter/2
Radius=6/2
=3 m
Height=14 m
Surface area=(2xx3x14)+(x3^2x2)
Surface area=263.8937829+56.54866776
Surface area=320.4424507 m^2
=320.4 m^2

Tin of paint: 90 m^2/3.70 euros
Number of tins needed=320.4/90
=3.56 cans of paint
Price=3.56x3.70
Price=13.172 euros

Hope this helps!
P.S. the “^” sign means “to the power of”

Elmer started out with$103 in his bank account .he spent $4 per week at the cafeteria for snacks.what is the slope (m) for this

pochemuha

Answer:

The equation is $y=-4x+103$

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

y is the amount left in the saving account

x is the number of weeks

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=-\$4\ per\ week$ --> is negative because is a decreasing function

The y-intercept or initial value is

$b=\$103$

substitute

$y=-4x+103$

Select the correct answer from each drop-down menu. In a circle with a radius of 7 feet, the radian measure of the central angle

trasher [3.6K]

In a circle, the number of radians is proportional to the relative length of the arc, in comparison to the radius. We have that if we denote by x the radians, the following proportionality holds, relating angles and lengths:
$\frac{x}{2\pi} = \frac{4}{2 \pi 7}$
because the total of angles in radians is 2pi and the total circumference is 2pi times the radius. Hence, by solving for x we get: x=4/7=0.57 rad

We also have that the area is proportional to the angles. The total are is $\pi r^2$ . Hence, A= $\frac{4}{2 \pi 7 } *\pi* 7^2= 14 square feet.$
