Answer:
The number is 6.
Step-by-step explanation:
Let the number be x then,
By the question,
2/3 * x + 10 = 14
2x / 3 = 14 - 10
2x / 3 = 4
Cross multiply ✖
2x = 12

15) Miguel made $6,743 in February and $8,152 in March. Which is the best 4 estimate for the amount of money Miguel earned when rounding to the nearest hundred. *
Answer:
$14,900
Step-by-step explanation:
Given that,
Miguel made $6,743 in February and $8,152 in March.
We need to find the amount of money Miguel earned.
It is equal to the sum of amount made in February and March.
Sum = $6,743 + $8,152
= $14895
Nearest hundred :
Sum = $14,900
Hence, the total amount is $14,900.

1.Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20. What are the least numbers of packs you should buy in order to have the same number of plates, utensils, and cups?
Answer:
Least no of packs = 120
Step-by-step explanation:
Given that,
Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20.
We need to find least numbers of packs you should buy in order to have the same number of plates, utensils, and cups.
It means we need to find the LCM of 8,12,20
Prime factorisation of 8 = 2×2×2
Prime factorisation of 12 = 2×3×2
Prime factorisation of 20=2×5×2
LCM = 120
Hence, there are 120 least number of packs you should buy in order to have the same number of plates, utensils, and cups

Step-by-step explanation:
72 x .25 = 18
72 - 18 = 54
Answer:
100% - 25% = 75%
72 x 0.75 = 54
He had 54 coins left
Step-by-step explanation:
Ok, to solve this question, first divide 72 by 100--- 72/100=.72
next, multiply .72*25 and u get--- 18
next subtract 72 and 18--- 72-18=54
the answer is the boy has 54 coins left

A researcher wants to be sure that the sample in her study is not unrepresentative of the distribution of ethnic groups in her community. Her sample includes 300 whites, 80 African Americans, 100 Latinos, 40 Asians, and 80 others. In her community, according to census records, there are 48% whites, 12% African Americans, 18% Latinos, 9% Asians, and 13% others. Is her sample unrepresentative of the population in her community
Answer:
Yes. Her sample is unrepresentative of the population in her community.
Step-by-step explanation:
a) Data and Calculations:
Population Study Census % Representative Over/Under
Sample Sample Representation
Whites 300 48% 288 (48% * 600) 12
African Americans 80 12% 72 (12% * 600) 8
Latinos 100 18% 108 (18% * 600) (8)
Asians 40 9% 54 (9% * 600) (14)
Others 80 13% 78 (13% * 600) 2
Total 600 100% 600 0
b) There is selection bias in her sample. A representative sample of 600 is the subset of a population that seeks to accurately reflect the characteristics of the larger group. When the sample for each category does not accurately represent the characteristics or attributes of the population categories, then it is unrepresentative.
Sampling is the collection of randomly chosen data from the entire population to come to an end conclusion about the variable to be determined or known.
Yes, the sample is unrepresentative of the entire population.
The reason for the sample being unrepresentative of the entire population in her community is that the selected sample is deviating a lot from the population count.
As per the computation, there is selection bias in her sample. This is because the representative sample is 600 that represents the entire population and reflects the characteristics of the larger group.
The sample becomes unrepresentative when the sample chosen does not accurately represent the true attributes of the population.

what is the distance from the origin to point A graphed on the complex plane below
Answer:
Coordinates of point A are
(-3,-2)
Origin lies in the center of coordinate system. That means that you can picture this as right triangle with sides 3 and 2 and you need to find hypotenuse of it.
Using pythagoras theorem we calculate:
h^2 = 3^2 + 2^2 = 13
h = sqrt 13
Answer is b

Evaluate the following expression when x = 3 and y = 4:
Fraction with x squared plus y cubed in the numerator and 2 plus x in the denominator.
Answer:
You would get 14.6
3 squared (3×3) equals 9 and 4 cubed (4×4×4) equals 64. Adding 9 and 64 equals 73. 2 plus 3 equals 5 and 73 divided by 5 is equal to 14.6
If the perimeter of this triangle is 15 centimeters, what is the value of n
Answer:
n = 5/2
Step-by-step explanation:
Add all of the sides up to make an equation

8n -5 = 15
8n = 20
n = 5/2
Answer:
[tex]0.4cm[/tex]
Step-by-step explanation:
[tex]n + 2n+1 + 5n-6 = 15\\[/tex]
[tex]8n -5 = 15[/tex]

Salt is poured from a container at 10 cm³ s-¹ and it formed a conical pile whose height at any time is 1/5 the radius of the above. At what rate is the height of the cone increasing when the height is 2 cm form the base of the cone?
Given :
Salt is poured from a container at 10 cm³ s-¹ and it formed a conical pile whose height at any time is 1/5 the radius of the above.
To Find :
At what rate is the height of the cone increasing when the height is 2 cm form the base of the cone.
Solution :
We know, volume of a cone is given by :
[tex]V = \dfrac{\pi r^2h}{3}[/tex]
Also, h = r/5
r = 5h
[tex]V = \dfrac{\pi (5h)^2h}{3}\\\\V = \dfrac{\pi 25h^3}{3}[/tex]
Differentiating above equation w.r.t h, we get :
[tex]\dfrac{dV}{dt} = \dfrac{d}{dt}(\dfrac{\pi 25h^3}{3})\\\\\dfrac{dV}{dh} = 25\pi h^2\dfrac{dh}{dt}\\\\\dfrac{dh}{dt}= \dfrac{\dfrac{dV}{dh}}{25\pi h^2 }\\\\\dfrac{dh}{dt}=\dfrac{10}{25\times 3.14\times 2^2}\\\\\dfrac{dh}{dt}=0.032\ cm/s[/tex]
Hence, this is the required solution.

A right triangle has one angle that measures 24°. What is the measure of the other acute angle?
Answer:
The measure of the other angle is 66°.
Step-by-step explanation:
Given that the total angles in a triangle is 180° so in order to find the other angles, you have to subtract :
90° + 24° + θ = 360°
114° + θ = 180°
θ = 66°
