Why Is 3 times 1/10 less than 3 times 10?k
3 times 1/10 is equal to 3/10, whereas 3 times 10 is equal to 30.
3/ 10 is less than 30.
We can write this as 3 * 1/10 compared to 3 * 10
If we divide both sides by 3, we then compare 1/10 and 10.
1/10 is less than 10, so 3 times 1/10 is less than 3 times 10.
We can rewrite 1/10 = 0.1, so 3 * 0.1 is 0.3 whereas 3 * 10 = 30.
Answer:
See Explanation
Step-by-step explanation:
When you multiply 3 * 1/10, 3 goes in the numerator so you get 3/10 which is 0.3
On the other hand 3*10 is 30.
0.3 is less than 30 that's why.
Here's the thing you had one pizza slice (equal to 1/10), and your parents gave you three times more the pizza slice. You will have three slices of pizza (each slice being 1/10) not 30 pizzas.
Hope that makes sense. I can explain again if you need me to!

Rename 2/5 and 1/2 using the least common denominator
the common denominator is 10 (between 5 and 2)
for each numerator:
we divide the common denominator with the denominator of each fraction and then multiply with the numerator of the fraction
first fraction's numerator:
10 (c.d.) : 5 (denominator) = 2
2 * 2 (numerator) = 4
second one:
10 (c.d.) : 2 (denominator) = 5
5 * 1 (numerator) = 5

(A) No, At α = .05, the Coefficient of price is not significantly different from zero, because :
The p-value (0.6019) obtained is greater than 0.05, Hence we fail to reject the null hypothesis.
B) the correlation Coefficient (r) :
Since ; r^2 = 0.01104
r = √0.01104
r = 0.1050714
The p-value obtained at α = .05 for r value of 0.1051 using the online p-value calculator is .602, this shows that correlation does not differ from 0.
Using :
r(√n-2) / √1 - r^2
0.1051(√27-2) / √1 - 0.01104
0.5255 / 0.9944646
= 0.5284250
For a 2 tailed test: α = .025
t0. 025 = 2.060 and - 2.060
Obtained t value is less than the critical, hence the null hypothesis stands
¿Para qué sirve saber estimar la capacidad de un recipiente utilizando el litro y el mililitro como unidades de medida?
Answer:
Estas unidades de capacidad son de uso frecuente en la manipulación de líquidos, así como en la estimación de la masa contenida del líquido dentro del recipiente si se conoce su densidad.
Además, permite clasificar hasta cuanto volumen y cuanta masa de un líquido determinado puede portar ese recipiente.
Step-by-step explanation:
Sirve la estimación de la capacidad de un recipiente dado en función de otros recipientes con capacidades de referencia, en cuyos casos corresponden al litro y el mililitro, respectivamente. Entonces, la capacidad total es aproximadamente la suma de las cantidades de adiciones de cada recipiente de referencia. La fórmula de estimación de capacidad del recipiente es:
[tex]V_{tot} \approx n_{l}\cdot (1000\,mL)+n_{L}\cdot (1\,mL)[/tex]
Donde:
[tex]V_{tot}[/tex] - Volumen total del recipiente, medido en mililitros.
[tex]n_{l}[/tex] - Cantidad de adiciones del recipiente con capacidad de un mililitro, adimensional.
[tex]n_{L}[/tex] - Cantidad de adiciones del recipiente con capacidad de un mililitro, adimensional.
Estas unidades de capacidad son de uso frecuente en la manipulación de líquidos, así como en la estimación de la masa contenida del líquido dentro del recipiente si se conoce su densidad.
Además, permite clasificar hasta cuanto volumen y cuanta masa de un líquido determinado puede portar ese recipiente.

Luther drives 17 miles to work each day . After work he takes a short cut home which is 14 miles . How many miles does he drive to and from work each week (5 days)
Step-by-step explanation:
17 miles = 1 day to work
14 miles =1 day to home
Therefore total miles driven in 5 days =
( 17×5) +(14×5) = 105+60
ANSWER =165 miles per week
Answer:
155 miles each week
Step-by-step explanation:
One day is 17 miles to and 14 miles home = 17+14 = 31
He does this 5 days a week

30 points! need asap The endpoints of CD¯¯¯¯¯¯¯¯ are C(5, 3) and D(−3,−6). Find the coordinates of the midpoint M. Coordinates of midpoint M:
Answer:
The midpoint is ( 1, -1.5)
Step-by-step explanation:
To find the midpoint
Add the x coordinates of the endpoints and divide by 2 to get the x coordinate of the midpoint
(5+-3)/2 = 2/2 = 1
Add the y coordinates of the endpoints and divide by 2 to get the y coordinate of the midpoint
(3+-6)/2 = -3/2 = -1.5
The midpoint is ( 1, -1.5)
Answer:
mid point = 1, -1.5
Step-by-step explanation:
mid point between two points C(5, 3) and D(-3, -6)
M = (x1 + x2)/2 , (y1 + y2)/2
mid point = (5 + (-3)) / 2 , (3 + -6)/2
mid point = 2/2 , -3/2
mid point = 1, -1.5

An air conditioning system can circulate 320 cubic feet of air per minute. How many cubic yards of air can it circulate per minute?
Step-by-step explanation:
It is given that, an air conditioning system can circulate 320 cubic feet of air per minute. We need to find how many cubic yards of air can it circulate per minute?
1 yard = 3 foot
1 feet = (1/3) yard
320 feet = 106.66 yard
[tex]320\ \text{feet}^3=320\times( \dfrac{1}{3})^3\ \text{yard}^3\\\\=11.85\ \text{yard}^3[/tex]
So, it will circulate 11.85 cubic yard of air per minute.

30 POINTS! ASAP PLEASE ∠1 is a supplement of ∠2, and m∠1=123∘. ∠2 is a complement of ∠3. Find m∠3. m∠3=
Answer:
angle 3 is 33 degrees.
Step-by-step explanation:
complementary angle-adds up to 90 degrees
supplementary angle- adds up to 180 degrees.
if angle 1 is 123, then angle two is 180-123 degrees(57)
if angle two is 57 degrees, angle 3 is 90-57 degrees (33)
Answer:
m∠3 = 33°Step-by-step explanation:
Since ∠1 and ∠2 are supplementary the sum of their angles is 180°
So to find ∠2 add ∠1 and ∠2 and equate them to 180° to solve for ∠2
So we have
∠1 + ∠2 = 180
∠2 = 180 - ∠1
From the question
m∠1 = 123°
So we have
∠2 = 180 - 123
∠2 = 57°
From the question , ∠2 is a complement of ∠3 the sum of their angles is 90°
That's
∠2 + ∠3 = 90
∠3 = 90 - ∠2
∠3 = 90 - 57
We have the final answer as
m∠3 = 33°Hope this helps you

Answer: C
Step-by-step explanation:

The function ƒ (x) = 12x gives the number of inches in x feet, and g(x) = 3.28x gives the approximate number of feet in x meters. Write a composite function that could be used to convert meters to inches.
Answer:
39.36xStep-by-step explanation:
Given the f(x) = 12x as the number of inches in x feet and g(x) = 3.28x gives the approximate number of feet in x meters, to find the composite function that can be used to convert metres to inches will give;
f[g(x)] (This means we are substituting the function that is measured in metres into the functions measured in inches).
Given g(x) = 3.28x,
f[g(x)] = f(3.28x)
f(3.28x) means that we are to replace the variable of x in f(x) with 3.28x as shown;
f(3.28x) = 12(3.28x)
f(3.28x) = 39.36x
f[g(x)] = 39.36x
Hence the composite function that could be used to convert meters to inches is expressed as 39.36x.

HURRY PLEASE if ray NP bisects angle MNQ and measure of angle MNQ= 8x + 12 and measure of PNQ= 78 degrees and measure of angle RNM= 3y -9, find the values of x and y
Answer:
the measure of x is 18° and the measure of y is 29°
Step-by-step explanation:
Step 1
Find the measure of angle x
we know that
If ray NP bisects <MNQ
then
m<MNQ=m<PNM+m<PNQ ------> equation A
and
m<PNM=m<PNQ -------> equation B
we have that
m<MNQ=(8x+12)°
m<PNQ=78°
so
substitute in equation A
(8x+12)=78+78-------> 8x+12=156------> 8x=156-12
8x=144------> x=18°
Step 2
Find the measure of angle y
we have
m<PNM=(3y-9)°
m<PNM=78°
so
3y-9=78------> 3y=87------> y=29°
therefore
the answer is
the measure of x is 18° and the measure of y is 29°

The equation for a parabola has the form y=ax2+bx+c, where a, b, and c are constants and a≠0. Find an equation for the parabola that passes through the points (−1,8), (2,−4), and (−6,−12).
Answer:
The equation for the parabola that passes through the points (−1,8), (2,−4), and (−6,−12) is [tex]y = -x^{2}-3\cdot x +6[/tex].
Step-by-step explanation:
Let be (−1,8), (2,−4), and (−6,−12) points contained in a parabola, which is represented by a second-order polynomial. To determine the constant of the second-order polynomial, the following system of equations must be solved:
[tex]a - b+c = 8[/tex]
[tex]4\cdot a +2\cdot b +c = -4[/tex]
[tex]36\cdot a -6\cdot b +c = -12[/tex]
There are several methods for solving this: Equalization, Elimination, Substitution, Determinant and Matrix. The solution of this system is: [tex]a = -1[/tex], [tex]b = -3[/tex] and [tex]c = 6[/tex]. Hence, the equation for the parabola that passes through the points (−1,8), (2,−4), and (−6,−12) is [tex]y = -x^{2}-3\cdot x +6[/tex].

f(x) = x^2 and g(x) = x - 3.
To find f(g(x)) we replace the x in f(x) by g(x).
f(g(x)) = (x - 3)^2
= x^2 - 6x + 9.
