Answer:
G. [tex] \frac{3.2}{2} = \frac{a}{8} [/tex]
Step-by-step explanation:
Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.
Thus:
[tex] \frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b} [/tex]
Therefore, the proportion that must be true is:
✔️[tex] \frac{3.2}{2} = \frac{a}{8} [/tex]
roger sells 23 necklaces at a fair a total of $ 201.25. Each necklaces is sold for the same price. what is the price of one necklaces ?
Answer:
$8.75
Step-by-step explanation:
It is given that,
Roger sells 23 necklaces at a fair a total of $ 201.25.
We need to find the price of 1 necklace. We can use unitary method to find it.
23 necklaces = $201.25.
For cost of 1 necklace, divide $201.25 by 23 as follows :
[tex]x=\dfrac{201.25}{23}\\\\=\$ 8.75[/tex]
So, the cost of 1 necklace is $8.75.

Two 6-sided dice are rolled. What is the probability that the sum of the two numbers on the dice will be greater than 9?
Answer:
The probability that the sum of the two numbers on the dice will be greater than 9 is 16.7%.
Step-by-step explanation:
To find the probability of the two fair six-sided dice getting a sum of 9 when thrown, we have to first find all the possibilities and those that are greater than 9.
The total number of possibilities for the outcome of the two dice would be (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1) and so on. Due to every possibility from the first dice branching out into six possibilities for the second dice, we can find the total number of possibilities to be 6 * 6 = 36 possibilities.
Now to find the total number of possibilities with a sum greater than 9. Due to the question asking for a sum of over 9, the possibilities will not include those with a sum of 9 itself. Hence, the only possibilities are when the first dice rolls 4 or more, since 3 + 6 (the maximum that the second dice can roll) is exactly 9.
Listing out all the possibilities, there are: (4, 6), (5, 5), (5, 6), (6, 4), (6, 5) and (6, 6). A total of 6 possibilities will get you a sum of 9 or above.
Finally, to find the percentage, we divide the number of possibilities with their sum over 9 by the total number of possibilities:
[tex]\frac{6}{36} \cdot 100\%[/tex]
[tex]= \frac{1}{6} \cdot 100\%[/tex]
[tex]= 16.7\%[/tex]
Hence, the probability that the sum of the two numbers on the dice will be greater than 9 is 16.7%.
Hope this helped!
The probability that the sum of the two numbers on the dice will be greater than is 1/6
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that, two dies are rolled we need to find the probability that the sum of the two numbers on the dice will be greater than 9,
The total outcomes = 36
{[1][1], [1][2], [1][3], [1][4], [1][5], [1][6],
[2][1], [2][2], [2][3], [2][4],[2][5], [2][6],
[3][1], [3][2], [3][3], [3][4], [3][5], [3][6],
[4][1], [4][2], [4][3], [4][4], [4][5], [4][6],
[5][1], [5][2], [5][3], [5][4], [5][5], [5][6],
[6][1], [6][2], [6][3], [6][4], [6][5], [6][6].}
Listing out all the possibilities, there are: {(4, 6), (5, 5), (5, 6), (6, 4), (6, 5) and (6, 6)} = 6
Therefore, the probability that the sum of the two numbers on the dice will be greater than 9 = 6/36 = 1/6
Hence, the probability that the sum of the two numbers on the dice will be greater than is 1/6

We need to find the GCF of 98y⁴ and 147y³.
Prime factorization of 98y⁴ = 7×7×2×y⁴
Prime factorization of 147y³ = 7×7×3×y³
Common factors are = 7×7y³

Answer:
[tex]m\angle ADC=132^\circ[/tex]
Step-by-step explanation:
The Law of Sines
It is an equation relating the lengths of the sides of a triangle to the sines of its opposite angles. If A, B, and C are the lengths of the sides and a,b,c are their respective opposite angles, then:
[tex]\displaystyle \frac{A}{\sin a}=\frac{B}{\sin b}=\frac{C}{\sin c}[/tex]
We have completed the figure with the variable x for angle BDA. Thus
[tex]\displaystyle \frac{35}{\sin 120^\circ}=\frac{30}{\sin x}[/tex]
Solving for x:
[tex]\displaystyle \sin x=\frac{30\sin 120^\circ}{35}[/tex]
Calculating:
[tex]\sin x=0.742[/tex]
[tex]x=\arcsin 0.742[/tex]
[tex]x\approx 48^\circ[/tex]
Since angles ADC and x are linear, their sum is 180° and:
[tex]m\angle ADC=180^\circ-48^\circ[/tex]
[tex]\mathbf{m\angle ADC=132^\circ}[/tex]

Solve the equation for the given variable. Justify each step.
9x + 2y = 5; y
Answer:
{x,y}={ 5/9,0}
Step-by-step explanation:
9x - 2y = 5
y = 0
9x - 2•() = 5
9x = 5
x = 5/9
By now we know this much :
x = 5/9
y = 0
⇒{x,y} = {5/9,0}
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]9x + 2y = 5[/tex]
solving the equation for y
[tex]9x + 2y = 5[/tex]
Step 1: Add -9x to both sides
[tex]9x+2y+-9x=5+-9x[/tex]
[tex]2y=-9x+5[/tex]
Step 2: Divide both sides by 2
[tex]\frac{2y}{2}=\:\frac{-9x+5}{2}[/tex]
[tex]y=\frac{-9}{2}x+\frac{5}{2}[/tex]
Thus, the value of y is:
[tex]y=\frac{-9}{2}x+\frac{5}{2}[/tex]
If we put y = 0 in the [tex]9x + 2y = 5[/tex]
[tex]9x+\left(0\right)=5[/tex]
[tex]9x=5[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]
[tex]\frac{9x}{9}=\frac{5}{9}[/tex]
[tex]x=\frac{5}{9}[/tex]
Thus, the value of x=5/9 at y=0

brakes, by measuring the distance of the skid marks. The

traveled after applying the brakes in a car moving
r miles per hour (r is the speed of the car).
If the distance the car traveled after applying the brakes
equals 88 feet, what, what was the speed of the car? *
*Round your answer to the nearest hundredth miles per hour.
Answer:
mph
9514 1404 393
Answer:
78.71 mph
Step-by-step explanation:
You're looking for the solution to ...
d = 88
0.0015r^2 +r = 88
0.0015r^2 +r -88 = 0
Using the quadratic formula*, we find ...
r = (-1 +√(1² -4(0.0015)(-88)))/(2×0.0015)
r = (-1 +√1.528)/0.003 = 0.236123/0.003 = 78.7077
The speed of the car was about 78.71 mph.
_____
* The quadratic formula will also give a negative answer of about -745 mph, which is not relevant to the situation.

Maria is draining her swimming pool. The depth of the water in the pool changes by −3/4 foot every hour.The depth of the water was 5 feet when she started draining. What is the depth of the water after 5 hours?
Answer: 1 1/4feet
Step-by-step explanation:
From the question, we are informed that the depth of the water in the pool changes by −3/4 foot every hour and that the depth of the water was 5 feet when she started draining.
The depth of the water after 5 hours will be:
= 5 - 3/4(5)
= 5 - 15/4
= 5 - 3 3/4
= 1 1/4 feet

half of the substance to remain is called the half-life of the substance.
The half-life of a pesticide is 10 years. A farmer initially applies 200 grams of the

After 20 years, there are
grams of pesticide left. Round your answer
to the nearest whole gram.
After 60 years, there are
grams of pesticide left. Round your answer
to the nearest hundredth of a gram.
After
years, there are approximately 1.03 grams of pesticide
left. Round your answer to the nearest whole year.
Answer:
Instructions are below.
Step-by-step explanation:
To calculate the final amount if a given substance, we need to use the following formula:
final amount= initial amount / (2^n)
n= elapsed time / half-life
For 20 years:
n= 20/10= 2
Final amount= 200/(2^2)
Final amount= 50 grams
For 60 years:
n= 60/10= 6
Final amount= 200/ (2^6)
Final amount= 3.125 grams
To calculate the elapsed time it is more complicated:
elapsed time= ln(ending amount/beginning amount) / (-decay constant)
ln= natural logarithm
decay constant= ln(2) / half-life
decay constant= 0.0693
elapsed time= ln(1.03/200) / (-0.0693)
elapsed time= 76.028
Prove:
n= 76.02/10= 7.602
Final amount= 200/(2^7.602)= 1.03 grams
