A _________ number differs from an integer because it has an integer part and a fractional part, even if the fractional part is 0
Answer:
Rational number
Step-by-step explanation:
Rational numbers are integers with fractional number for example 2/9 is a rational number and so is 4/5 ,6/10, 2.5 ,6 ,9 etc.

Step-by-step explanation:
Going 4 miles north would move the point (4, -2) 4 units up. When done so, the point (4, 2) is reached.
Going 4 miles south would move the point (4, -2) 4 units down. When done so, the point (4, -6) is reached.

what the 51st term of -17, -25, -33
Answer:
The 51st term of the arithmetic sequence is - 417
Step-by-step explanation:
The formula for determining the nth term of an arithmetic sequence is expressed as Tn = a + d(n - 1)
Where a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = - 17
d = - 25 - - 17 = - 33 - - 25 = - 8
n = 51
We want to determine the value of the 51st term, T51. Therefore,
T51 = - 17 + - 8(51 - 1)
T51 = - 17 - 400
T51 = - 417

Triangle ABC has vertices at (5, 0), (- 1, - 4) , and (3, - 6) . What is the perimeter of ABC , rounded to two decimal places ?
Answer:
18.01 units to 2 dec. places.
Step-by-step explanation:
Calculate the length of the 3 lines of the triangle
AB = √ [(5 --1)^2 + ( 0 - -4)^2]
= √(36 + 16)
= √52
= 7.211.
BC = √ [(-1-3)^2 + (-4- -6)^2]
= √(16 + 4)
= √20
= 4.472.
CA = √ [(3-5)^2 + (-6-0)^2]
= √(4 + 36)
= √40
= 6.325.
So the perimeter = 7.211 + 4.472 + 6.325
= 18.008

Name r 13 EUA 18. Find the measure of angle A Date Period A 16 139° B A= 13 20 19. Solve the triangle ABC with side lengths a = 14cm, b = 9cm, c = 6cm a = A= b = B= C= C =
Answer:
A = 137° a = 14 cm
B = 26° b = 9 cm
C = 17° c = 6 cm
Step-by-step explanation:
Cosine rule
[tex]c^2=a^2+b^2-2ab\cos (C)[/tex]
[tex]\implies C=\cos^{-1}\left(\dfrac{c^2-a^2-b^2}{-2ab}\right)[/tex]
where:
c is the side opposite angle Ca and b are the sides with C as the included angle.Given:
a = 14 cmb = 9 cmc = 6 cm[tex]\implies C=\cos^{-1}\left(\dfrac{6^2-14^2-9^2}{-2(14)(9)}\right)[/tex]
[tex]\implies C=\cos^{-1}\left(\dfrac{241}{252}\right)[/tex]
[tex]\implies C=16.99128694..\textdegree[/tex]
Sine Rule
[tex]\sf \dfrac{sinA}{a}=\dfrac{sinB}{b}=\dfrac{sinC}{c}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
[tex]\sf \implies \dfrac{sinB}{9}=\dfrac{sin(16.991..)}{6}[/tex]
[tex]\sf \implies B=sin^{-1}\left(\dfrac{9sin(16.991..)}{6}\right)=25.99797699...\textdegree[/tex]
Sum of interior angles of a triangle = 180°
⇒ ∠A + ∠B + ∠C = 180°
⇒ ∠A = 180° - 25.997...° - 16.9912...°
⇒ ∠A = 137.0107361...°

How many different possible outcomes are there if you roll three six-sided dice in the shape of a cube?
Answer:
There are 36 outcomes. Of these, there are 2 that have both 1 and 3.
solve the quadratic figures 3x^2 + x - 5
To solve this quadratic equation we should first see if it is possible to factorise it into two seperate brakets. In this case there are no numbers which multiply to give -5 and add to give 3. Thus we should resort to using the quadratic formula which is used when equations cannot be solved by inspection. The quadratic formula is x=(-b+-(b2-4ac)1/2)/2a. Values for a,b and c can be lifted from the question. ax2+b-c=0 so in this question a=3 b=1 and c=-5. Inputing these into the equation will give two results.
The answers are
x=1.135 or x=-1.468
both of these answers make the original equation true

Answer:
x = 0.17
Step-by-step explanation:
Solve for x:
First, take the ln of both sides:
ln(1/16) = ln(8^(4x-2))
You can now bring down (4x-2) in front of the ln:
ln(1/16) = (4x-2)ln(8)
ln(1/16)/ln(8) = 4x-2
4x = ln(1/16)/ln(8) + 2
x = ln(1/16)/4ln(8) + 1/2
x = 0.17
A bag contains green and black counters.

-
4
of the counters are black
Write the ratio of green to black counters.
Answer:
3:1
Step-by-step explanation:
if 1/4 of the counters are black then it means the total counters are 4 and so there are 3 remaining and those become the green counters
The ratio of green to black counters is 3:1
What is the Ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that A bag contains green and black counters, 1/4 of the counters are black.
Since, 1/4 is black counters therefore, 1 - 1/4 are green counters
So, there are 3/4 green counters
Ratio = (3/4)/(1/4) = 3/1 3:1
Hence, The ratio of green to black counters is 3:1

Wanwan is 1.69 m tall and is flying a kite. She holds the string of the kite just above her head. The string is 80 m long and makes, x°, between 54° and 55° with the horizontal. Assuming that the string is taut, estimate (2 decimal places) the vertical height of the kite from the ground
Since, the kite is taut the vertical height of the kite from the ground is 66.82 meters
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore, the string length is the hypotenuse side. The angle formed is between 54 degree to 55 degrees. Therefore,
sin 54.5 = opposite / hypotenuse
sin 54.5 = h / 80
cross multiply
h = 80 × sin 54.5
h = 80 × 0.81411551835
h = 65.1292414685
Therefore, the vertical height of the ground from the ground is as follows:
vertical height = 65. 13 + 1.69 = 66.82 meters

What is halfway between 400,000 and 500,000?
Answer:
450,000
This is because 400,000 and 500,000 have no other numbers that could be the middle, so it has to be directly in-between both numbers.
__________________________________________________________
Questions related to this topic? Please ask me in the comments box.
Answer:
450,000
Step-by-step explanation:
500,000-400,000 = 100,000
100,000/2 = 50,000
400,000 + 50,000 = 450,000
Finding half of the value between 500,000 and 400,000 results in 50,000 and you can add that to the lesser value to get to the halfway point between the two numbers.

Some red, white, and blue candies
were placed in a bowl. Some contain nuts,
and some do not. Suppose one of the candies were chosen randomly from all
the candies in the bowl.
probability?
Which of the following represents a conditional
O A. The probability that it does not contain any nuts, given that the
candy is red
B. The probability that it contains nuts and is white
O c. The probability that the candy is not red
• D. The probability that the candy is blue
Reason:
The keyword "given" is a universal indicator we're dealing with conditional probabilities. It sets up prior knowledge to reduce down the sample space.
The fact that we know the candy is red means that we only focus on the red candies (and shrinks down the set).
Conditional probability is represented by probability that the candy is blue.
What is Conditional Probability?One of the fundamental ideas in probability theory is the idea of the conditional probability formula. The conditional probability formula calculates the likelihood of an event, say B, given the occurrence of another event, say A.
By knowing the conditional probability of event B given that event A has occurred and the individual probabilities of events A and B, the Bayes theorem may be used to calculate the conditional likelihood of event A given that event B has occurred.
