How many times greater is 1 kilogram than 1 microgram?
A. 10^9
B. 10^-9
C. 1/10^9
D. 10^8
Final answer:
1 kilogram is 10^9 times greater than 1 microgram because 1 kg equals 1000 grams, and there are 10⁶ micrograms in a gram, equating to 10⁹ µg/kg.So,option A.10⁹ is correct.
Explanation:
To determine how many times greater 1 kilogram is than 1 microgram, we need to understand the metric prefixes and their corresponding values. Knowing that 'micro' denotes 10⁻⁶, we can establish that 1 microgram (µg) equals 10⁻⁶grams (g). Since 1 kilogram (kg) equals 1000 grams, we then convert kilograms to micrograms by multiplying by 10⁶:
1 kg = 1000 g x 10⁶ µg/g = 10⁹ µg.
Thus, 1 kilogram is 10⁹ times greater than 1 microgram, which corresponds to option A.

Solve the system of equations. y = x ^ 2 - 3x + 6 y = 2x + 6
Answer:
the answer is A.
Step-by-step explanation:
The values of the system of equations y=[tex]x^{2}[/tex]-3x+6, y=2x+6 is (0,6),(5,16).
What is equation?Equation is relationship between two or more variables that are expressed in equal to form.Equations of two variables look like ax+by=c.It may be linear equation, quadratic equation,cubic equation.
How to solve the equation?We have been given two equations as y=[tex]x^{2}[/tex]-3x+6 and y=2x+6 and we are required to solve the equations for the value of x.
Putting the value of y from second equation in first equation.
2x+6=[tex]x^{2}[/tex]-3x+6
Cancellng 6 from both sides.
[tex]x^{2}[/tex]-5x=0
x(x-5)=0
x=0,x-5=0
x=0,x=5
Putting the values of x in second equation to get the value of y.
y=2x+6
y=2(5)+6
=10+6
y=16
y=2x+6
y=2*0+6
=6
Points will be (0,6),(5,16).
Hence the values of the system of equations y=[tex]x^{2}[/tex]-3x+6, y=2x+6 is (0,6),(5,16).

B. (-2, 15)
C. (1, 12)
D. (12, 1)
Answer:
B. (-2, 15)
Step-by-step explanation:
Pretend that your fixed point [2, 9] is at the origin for now by translating it two units west then nine units south [0, 0]. Now, the same goes for [6, 3]. Translate it two units west then nine units south to get [4, -6]. Then, according to the 180°-rotation rule, you take the OPPOSITE of both the x-coordinate and y-coordinate:
[4, -6] → [-4, 6]
Now, that you have your rotated point, we have to shift EVERYTHING BACK to the way it was from when we shifted the fixed point of [2, 9] to the origin. We do that by translating everything in reverse order, which is 9 blocks north then 2 blocks east:
→ [0, 0] back to [2, 9]
Translation
→ [-4, 6] to the new coordinate of [-2, 15]

The measure of one of the small angles of a right triangle is 15 less than twice the measure of the other small angle. Find the measure of both angles
Answer:
35° and 55°
Step-by-step explanation:
The sum of the angles of a right rectagle is 180°, with a right angle of 90°.
The tell us that A = 2B-15, so:
180° = 90° + A + B
180° = 90° + 2B - 15 + B
180° - 90° + 15 = 2B + B
105° = 3B
B = 105°/3 = 35°
Now, let's find A:
A = 180° - 90° - 35° = 55°
Using the properties of a right triangle and setting up an equation based on the relationship between the two small angles, we find that the angles measure 35 degrees and 55 degrees, respectively.
To solve the problem involving the angles of a right triangle, we recall that the sum of the angles in any triangle is 180 degrees. In a right triangle, one angle is always 90 degrees, which leaves a total of 90 degrees to be shared between the other two angles.
If we let x represent the measure of one of the small angles, then the problem tells us that the other angle is 2x - 15 degrees.
Therefore, we can set up the following equation to solve for x:
x + (2x - 15) + 90 = 180
Combining like terms gives us:
3x - 15 + 90 = 180
3x + 75 = 180
Now, we subtract 75 from both sides of the equation:
3x = 105
Finally, we divide by 3 to find the measure of x:
x = 35
Having found that one of the small angles measures 35 degrees, we can now find the other small angle:
2x - 15 = 2(35) - 15
= 70 - 15
= 55 degrees.
So, the two small angles of the right triangle are 35 degrees and 55 degrees.

Maria gave the casheir $50.00 to pay for three shirts. The casheir gave her back $8.75 in change. Each shirt cost the same amount. What is the cost in dollars and cents for each shirt?
Answer:
$13.75
Step-by-step explanation:
First figure out how much she paid, by taking the change from the $50
50 - 8.75 = 41.25
She paid $41.25 dollars on three tee-shirts.
Now take how much she spent and divide it on the number of items (tee-shirts) to figure how much each one cost.
41.25 divided by 3 = 13.75
$13.75
Each Tee-shirt cost $13.75
Final answer:
To find the cost of each shirt, subtract the change given from the total amount paid and then divide by the number of shirts purchased.
Explanation:
In this scenario, Maria paid $50.00 for three shirts and received $8.75 in change. To find the cost of each shirt, we subtract the change from the total amount she gave. $50.00 - $8.75 = $41.25. Since she bought three shirts, we divide $41.25 by 3 to find the cost of each shirt. The cost of each shirt is $13.75.
Chad used the table to show the ratios of the different types of sports game cards that he owns. For every 4 defense cards, he owns 2 offense cards. Which graph represents the proportional relationship between his defense and offense cards?
Only the graph A represents the proportional relationship between the variables.
Given that :
For every 4 defense cards ; there are 2 offense cards :
Defense cards = y
Offense cards = x
For proportional relationship :
y α x
y = kx
k = y/x
k = constant of proportionality
k = 4/2
k = 2
y = 2x
The value of y when x = 4
The value of y when x = 4 When ; x = 4
The value of y when x = 4 When ; x = 4 y = 2×4 = 8
Only graph A gives the proportional value of y when x = 4
Hence, Graph A represents the proportional relationship between defense and offense.
Learn more : https://brainly.com/question/20689669
Final answer:
The correct graph would show a straight line through the origin with a slope of ½, reflecting the 2:1 ratio of defense to offense sports game cards Chad owns.
Explanation:
The subject of this question is Mathematics, and it pertains to the concept of ratios and proportional relationships, which is typically taught at the Middle School level. To determine which graph represents the proportional relationship between Chad's defense and offense sports game cards, we must consider that for every 4 defense cards, he owns 2 offense cards. This establishes a constant ratio of defense to offense cards of 2:1.
A graph that accurately represents this relationship would be a straight line through the origin (0,0) that has a slope of ½, because for every 2 units increased in the defense (x-axis), there should be a 1 unit increase in the offense (y-axis). This is because the graph of a proportional relationship is always a straight line that passes through the origin, and the slope of the line reflects the ratio of the quantities compared.

Final answer:
The square root of 15 is approximately 3.87 when rounded to the nearest hundredth, following the rules of rounding where you round down if the third decimal is less than 5.
Explanation:
The question asks for the square root of 15 rounded to the nearest hundredth. To find this, we calculate the square root using a calculator, which gives us an approximate value. We then apply the rules of rounding: if the digit after the hundredths place is 5 or higher, we round up, and if it is lower than 5, we round down. This ensures that our answer is as close as possible to the actual square root without exceeding two decimal places.
Performing the calculation, we find that the square root of 15 is approximately 3.87298. Since the third decimal place (after the hundredth) is '2', which is less than 5, we round down. Therefore, the square root of 15 rounded to the nearest hundredth is 3.87.
For the quadrilateral ABCD diagonal BD is an angle bisector for angles B and D. Find the m∠DAC if m∠ADB = 20°, m∠DBC = 60°.
Answer:
70°
Step-by-step explanation:
If in the quadrilateral ABCD diagonal BD is an angle bisector for angles B and D, then
∠ABD ≅ ∠DBC;∠ADB ≅ ∠BDC.Consider triangles ABD and CBD. In these triangles,
∠ABD ≅ ∠DBC;∠ADB ≅ ∠BDC;BD ≅ BD.Hence, triangles ABD and CBD are congruent by ASA postulate.
So, AD ≅ DC.
Now, consider triangle ADC. This is an isosceles triangle, because AD ≅ DC. In this triangle, m∠ADC = m∠ADB + m∠BDC = 20° + 20° = 40°. AC is the base. Angles DAC and DCA are congruent as adjacent angles to the base AC, so
m∠DAC = 1/2 (180° - 40°) = 70°
Answer:
m∠DAC = 70°
m∠ACB = 30°

The inequalities created from the number pair 5 and -11 are '5 > -11' and '-11 < 5'. These represent that 5 is greater than -11 and that -11 is less than 5.
Explanation:To write two inequalities using the number pairs 5 and -11 with the symbols < and >, we consider the numeric value and sign of the numbers. We know that any positive number is always greater than a negative number. This gives us the first inequality: 5 > -11
Now, if we want to write an inequality using <, then we swap the order of numbers. Thus: -11 < 5
These statements tell us that 5 is greater than -11 and -11 is less than 5, which demonstrates how to use < and > inequalities with numbers.
