A bag contains green and black counters.
1
-
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

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.

Find the volume of the sphere, round your answer to the nearest tenth
Answer:
904.8 units^3
Step-by-step explanation:
The formula for the area of a circle is [tex]4/3 \pi r^3[/tex]
By the picture we know r = 6
Thus our answer is 4/3 * π * [tex]6^3[/tex]
This is the same as 4/3 * 216 * π = 904.778684234
Rounding to the nearest tenth yields 904.8 units^3

Tuesday he used 3/5 as many of 1/8
Answer:
19/40 = 0.475 You can use either the fraction or the decimal
Step-by-step explanation:
3/5 - 1/8 = 3 · 8/5 · 8 - 1 · 5/8 · 5 = 24/40 - 5/40 = 24 - 5/40 = 19/40
Answer:
[tex] \frac{3}{5} - \frac{1}{8} = \frac{19}{40} [/tex]
TOTAL:
=0.475
Step-by-step explanation:
3/5 - 1/8 = 3.8/5.8 - 1.5/8.5 = 24/40
- 5/40 = 24-5/40 - 24-6/40 =19/40
✿For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 8) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 8 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.
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...°

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

A random sample is meant to be an unbiased representation of the larger population.
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.
We have,
Some red, white, and blue candies were placed in a bowl.
Some contain nuts, and some do not.
Here we are only focusing on the red candy which shows we have reduce the sample space.
