20 = 5(-3 + x)

20 = 5x - 8        distributive property

28 = 5x              add 8 to both sides

28/5 = 5x/5       divide by 5 to both sides

x = 5.6               answer

sorry i dont know the second way. hope this helps!

3. A mass spectrometer is an instrument that can be used to determine the mass of a substance. A student measured the mass of 3
Tju [1.3M]

The error that occurred is a systematic error.

<h3>What is random error?</h3>

Random error is a type of error that causes one measurement to differ slightly from the next.

<h3>What is systematic error?</h3>

Systematic error is a type of error that affects measurements in the same amount or by the same proportion, provided that readings are taken in the same way.

The three measurements 548.5 g, 548.9 g, and 548.7 g differ slightly but in the same amount and proportion.

Therefore, a systematic error occurred during the determination of the mass of the substance because the readings were taken in the same way and the measurement differ in the same amount.

He radius of a circle is 2 kilometers. What is the area of a sector bounded by a 45° arc?
faust18 [17]
We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²

if 360° (full circle) has an area of---------> 12.56 km²
 45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²

the answer is
1.57 km²

Cynthia is in the process of constructing two tangent line segments from a point outside circle O to circle O as shown. Which li
Allisa [31]

Answer:

(B) Segments MA and MB

Step-by-step explanation:

The tangent to the circle at a point is perpendicular to the radius of the circle drawn to the point of tangency.

Tangent at a point is unique.

Since there can be no two tangents at a point on circle, the options (b) and (c) are ruled out.

Now, if OA is perpendicular to MA, MA is the tangent else if OA is perpendicular to PA, PA is the tangent. Same is the case with point B.

Tangents from the same external point has same length.

MA = MB since they are the radii of the same circle with center M.

Hence, MA and MB meet all the requirements of the tangents.

I really need helppppp
JulijaS [17]

Answer:

The correct answer is C.

Step-by-step explanation:

In the equation of a circle, if the variable x and y are added or subtracted by any number before being squared, the entire circle with be translated in the opposite amount that was added or subtracted to the circle. For example, (x-8)^2 + (y-8)^2 shifts the center 8 to the right and up of the origin, (x+1)^2+(y+4)^2 shifts the center 1 to the left and 4 down of the origin. Since the circle represented in the graph is centered directly on the origin, that means the equation will have x^2+y^2, which helps you eliminate choices A and C. For the equation of a circle, the radius is the value of the constant on the right side of the equal sign taken to its square root. Since the radius of this circle is 8, that means the constant at the right side of the circle would be 64 or 8^2, so the correct answer would be choice C: x^2+y^2=8^2.
