Answer:
195
Step-by-step explanation:
create a proportion: # tests/time = # tests/time
let 't' = # tests graded
117/3 = t/5
cross-multiply to get:
3t = 585
t = 585/3 which equals 195
Terry spends $49.00 on apples. Howard buys 12 apples. Each apple costs $7.00. How many apples did Terry buy?
Answer:
7

Answer:
17+2n
Step-by-step explanation:
At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter. From that moment forward, the medicine's concentration drops by 30% percent each hour. Write a function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected. If anyone responds, thank you <3
Answer: [tex]C(t) = 120(1-0.30)^t[/tex]
Step-by-step explanation:
Exponential equation for decay:[tex]y= A(1-r)^t[/tex], where A = initial value, r= decay rate , t= time.
As per given, A = 120ml , r= 0.30
[tex]C(t) = 120(1-0.30)^t[/tex]
Hence, the required function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected.
[tex]C(t) = 120(1-0.30)^t[/tex]

Answer:
D. [tex]\sqrt{333}[/tex]
Step-by-step explanation:
To solve the problem, we can use the distance formula which is:
[tex]\sqrt{(x_{1} -x_{2} )^2+(y_{1}- y_{2} )^2}[/tex]
We can substitute the points (-7, 6) and (-4, -12):
[tex]\sqrt{(-7-[-4])^2+(6-[-12])^2} \\\sqrt{(-3)^2+(18)^2} \\\sqrt{9+324} \\\sqrt{333}[/tex]

Someone plz help its doe in 10 min
Answer:
The factors of x² - 3·x - 18, are;
(x - 6), (x + 3)
Step-by-step explanation:
The given quadratic expression is presented as follows;
x² - 3·x - 18
To factorize the given expression, we look for two numbers, which are the constant terms in the factors, such that the sum of the numbers is -3, while the product of the numbers is -18
By examination, we have the numbers -6, and 3, which gives;
-6 + 3 = -3
-6 × 3 = -18
Therefore, we can write;
x² - 3·x - 18 = (x - 6) × (x + 3)
Which gives;
(x - 6) × (x + 3) = x² + 3·x - 6·x - 18 = x² - 3·x - 18
Therefore, the factors of the expression, x² - 3·x - 18, are (x - 6) and (x + 3)

I NEED THE ANSWER FOR THIS QUESTION ASAP PLEASE EXPLAIN THE STEP BY STEP I NEED TO SHOW WORK
Answer:
45 3/10 miles per hour
Step-by-step explanation:
Distance travelled by the car = 30 1/5 miles
Time taken = 2/3 of an hour
Average speed = distance travelled / time taken
= 30 1/5 miles ÷ 2/3 of an hour
= 151/5 ÷ 2/3
= 151/5 × 3/2
= (151 * 3) / (5 * 2)
= 453 / 10
= 45 3/10 miles per hour
Average speed = 45 3/10 miles per hour

Question Continuation :
1.construct a table for the sample space of the random experiment.
2.using the sample space find the probability that the total score of the two dice is:
a. greater than or equal to 5
b. greater than 5 but less than 8.
Answer:
See belowStep-by-step explanation:
#5
P(man) = 8/15P(lady) = 7/15(a)
P(both ladies) = 7/15*6/14 = 1/5(b)
P(both men) = 8/15*7/14 = 4/15(c)
P(same sex) = P(both men or both ladies) = 1/5 + 4/15 = 7/15(d)
P(different sexes) = P(man and lady or lady and man) = 8/15*7/14 + 7/15*8/14 = 8/15Another way:
P(different sexes) = 1 - P(both ladies) - P(both men) = 1 - 1/5 - 4/15 = 8/15#6

P(5<sum<8) = P(6 or 7) = 5/16Solve 3b = 6v – 3b, for v.
6b-6
b
b-6
0
Answer:
b = v
Step-by-step explanation:
3b = 6v – 3b
Add 3b to each side
3b+3b = 6v – 3b+3b
6b = 6v
Divide by 6
6b/6 = 6v/6
b = v

Answer:
m∠6 = 110°
Step-by-step explanation:
∠6 and ∠8 are known as corresponding angles meaning they are equal to each other. Since m∠8 = 110°, m∠6 also equals 110°.
Answer:
11o degree
Step-by-step explanation:
angle 6 is 110 degree because the relation between angle 6 and angle 8 is that they are corresponding angles and corresponding angles are always equal.

a park is 9/10 mile long and 4/5 mile wide. What is the area of the park? ENTER ANSWER AS A FRACTION FOR EXAMPLE: 4/10.
The park formed like a rectangle so :
Area = length × width
Area = ( 9/10 ) × ( 4/5 )
Area = 9 × 4 / 10 × 5
Area = 9 × 2 × 2 / 5 × 5 × 2
Area = 18 / 25

A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estimates it will take students an average of 2 minutes to complete each multiple-choice question and an average of 3.5 minutes to complete each short-answer question.
Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.
Answer:
8 questions each for short answer questions and 8 questions of Multiple Choice Questions type.
A total of 16 questions.
Step-by-step explanation:
The number of multiple-choice questions and the number of short answer type questions are the same.
Let it be equal to [tex]x[/tex]
→Average time it takes to attempt multiple choice question = 2 minutes
→Total time it takes to attempt multiple choice question = [tex]2 * x[/tex] minutes
→Average time it takes to attempt short answer type question = 3.5 minutes
→Total Time it takes to attempt short answer type question = [tex]3.5 * x[/tex] minutes
Total time for the test should be less than 45 minutes.
Now finally, we can make an equation out of the information listed above:
[tex]2x +3.5x <45[/tex]
[tex]\\ 5.5x <45[/tex]
[tex]x < 8.18[/tex]
Hence the value of [tex]x = 8[/tex]

Answer:
The answer is 3/4 because 2/4 + 1/4 = 3/4.
What is 50% of 50% of 50%
Step 1:
50%= 50/100 = 0.5
Step 2:
50% of 50%= (50×0.5)/100= 0.25
Step 3:
50% of 50% of 50% = (50×0.25)/100= 0.125
