What is 10 times larger than the 7 in this number 16372
Answer:
700
Step-by-step explanation:
I am slightly confused by your wording, but Im assuming you mean the expanded form.
In the base ten system, the second to last digit is the tens place. Therefore, the 7 represents 7*10 = 70
10 times larger than 70 is 700
If the angles are represented in degrees, find both angles: \cos(3x+13)=\sin(2x+42) cos(3x+13)=sin(2x+42)
Answer:
cos34°
sin56°
Step-by-step explanation:
Sin(2x+42)= sin90-(3x+13)
Sin(2x+42) = sin(90-13-3x)
Sin(2x+42) = sin(77-3x)
2x + 42 = 77-3x
5x. = 35
X = 7
If x = 7
cos(3x+13) = cos((3*7)+13)
cos(3x+13) = cos(21+13)
cos(3x+13)= cos34
And
sin(2x+42) = sin((2*7)+42)
sin(2x+42)= sin (14+42)
sin(2x+42) = sin56

FIND THE SMALLEST ANGLE IN THE TRIANGLE! PLEASE HELP!! 25 POINTS!!
From the side/angle inequality, we see that the smallest angle of a triangle must be opposite its shortest side. In this case, that angle is opposite the shortest side [tex]\overline{AC},[/tex] so our answer is [tex]\boxed{\angle B}.[/tex]
As for finding its measure (which I'm aware the question probably didn't ask for), we can use the law of cosines:
[tex]5^2=6^2+7^2-2(6)(7)\cos B[/tex]
[tex]\cos B=\frac{5}{7}\implies\angle B\approx\boxed{44.4^\circ}.[/tex]

A car with 15 gallons of gasoline drives 420 miles until the tank is empty. Write a linear equation that describes the amount of gas left in the car, y, after driving x miles.
Answer:
[tex] y = -\dfrac{1}{28}x + 15 [/tex]
Step-by-step explanation:
The car uses 15 gallons of gasoline to drive 420 miles.
(15 gal)/(420 mi) = 1/28 gal/mi
The car uses 1/28 gallon of gasoline per mile.
y = mx + b
When x = 0, at the start of the drive, the car has 15 gallons of gasoline.
y = mx + 15
Then for every mile it travels, the amount of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.
[tex] y = -\dfrac{1}{28}x + 15 [/tex]

Complete the square to make a perfect square trinomial. Write the result as a binomial square. q2−23q
Answer:
[tex]\left(q-\dfrac{23}{2}\right)^2[/tex]
Step-by-step explanation:
Given the expression: [tex]q^2-23q[/tex]
To complete the square, we follow these steps:
Step 1: Identify the coefficient of q
Coefficient of q=-23
Step 2: Divide the coefficient of q by 2
[tex]=-\dfrac{23}{2}[/tex]
Step 3: Square your result from step 2 and add it to the equation
This gives us: [tex]q^2-23q+\left(-\dfrac{23}{2}\right)^2[/tex]
We have now completed the square.
Step 4: Write the result as a binomial square.
To write it as a binomial square, pick the variable and add the term in the bracket.
Therefore:
[tex]q^2-23q+\left(-\dfrac{23}{2}\right)^2=\left(q-\dfrac{23}{2}\right)^2[/tex]
The perfect square form of the given expression will be [tex](q-\dfrac{23}{2})^2[/tex].
The given expression is [tex]q^2-23q[/tex].
It is required to write the given expression as a perfect square polynomial or trinomial.
We will use the identity [tex](a+b)^2=a^2+2ab+b^2[/tex].
So, the first term from the given expression will be [tex]a=q[/tex].
To find the second term b, divide the 2nd term of the given expression by 2,
[tex]b=\dfrac{-23}{2}[/tex]
So, the given expression can be written in the perfect square form as,
[tex]a^2+2ab+b^2=q^2-23q+(\dfrac{-23}{2})^2\\=(q-\dfrac{23}{2})(q-\dfrac{23}{2})\\=(q-\dfrac{23}{2})^2[/tex]
Therefore, the perfect square form of the given expression will be [tex](q-\dfrac{23}{2})^2[/tex].

1. Determine a rule that could be used to explain how the volume of a
Cylinder or cone is affected when the radius is multiplied by a positive
number.
Answer:
See explanation
Step-by-step explanation:
Solution:-
- We will use the basic formulas for calculating the volumes of two solid bodies.
- The volume of a cylinder ( V_l ) is represented by:
[tex]V_c = \pi *r^2*h[/tex]
- Similarly, the volume of cone ( V_c ) is represented by:
[tex]V_c = \frac{1}{3}*\pi *r^2 * h[/tex]
Where,
r : The radius of cylinder / radius of circular base of the cone
h : The height of the cylinder / cone
- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.
- We will represent a proportionality of Volume ( V ) with respect to ( r ):
[tex]V = C*r^2[/tex]
Where,
C: The constant of proportionality
- Hence the proportional relation is expressed as:
V∝ r^2
- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:
[tex]V = C*(a*r)^2\\\\V = C*a^2*r^2[/tex]
- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ).
- Hence, the relations for each of the two bodies becomes:
[tex]V = (\frac{1}{3} \pi *r^2*h)*a^2[/tex]
&
[tex]V = ( \pi *r^2*h)*a^2[/tex]

Justify your answer.
Answer:
Step-by-step explanation:
The given data is represented in the attachment.
a) Explain why yields from one type of corn are not independent of the yields from the other type of corn.
Yields from one type of corn are not independent of the yields from the other type of corn because, as the corns are planted in two similar plots, they could compete during watering process, even the amount of nutrients shared and the type of air. This means one corn may get more nutrients than the other. Therefore, they are not independent (they are dependent).
b) Based on the summary statistics, GM is expected to more likely obtain yield greater than 123, because 123 is greater than mean for regular corn but less than mean for GM corn.
Thus,
P(yield>123|GM)>0.5; and P(yield>123|Regular)<0.5
what is the probability of choosing an even number from the set of numbers 1,2,3,4,5,6,7,8,9,10

The set of numbers are: 10
1,2,3,4,5,6,7,8,9,10
Even Numbers: 5
2,4,6,8,10
Probability = [tex]\frac{NumberOfFavourableOutcomes}{TotalNumberOfOutcomes}[/tex]
P = [tex]\frac{Even Numbers}{Total Numbers}[/tex]
P = [tex]\frac{5}{10}[/tex]
P = [tex]\frac{1}{2}[/tex]
So, the probability of getting an even numbers out of this set is 1/2
Answer:
The probability of this set of numbers is 1/2.
Step-by-step explanation:
Probability is the odds of an event happening. It is expressed by writing it as a fraction, decimal, or a percent.
The formula for probability is the number of favorable outcomes divided by the total number of outcomes. In this case, we have odd and even numbers. The even numbers in this set are 2, 4, 6, 8, and 10.
These are the favorable outcomes.
Since there are 5 even numbers, there are 5 favorable outcomes.
There are total of 10 outcomes. Therefore P(Even number)= 5/10.
Don't forget to always simplify. You can divide the numerator and denominator by 5. 5 divided 5 is 1 and 10 divided by 5 is 2.
Therefore, the probability of choosing an even number from this set of numbers is 1/2.

Answer:
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, negative 5) to (negative 2, negative 5). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (4, 2) to (5, 2).
Step-by-step explanation:
The floor function graphs as horizontal segments 1 unit long, each 1 unit up from the segment to its left. It will have a closed circle at the left end of the segment, and an open circle at the right end.
Since 2 is subtracted from the floor of the x-value, the closed circle at the left end of the segment will have coordinates (x, x-2). The only offered choice meeting that condition is the 3rd choice listed here.
