Answer:
4/5
Step-by-step explanation:
the numerator of fraction is 1 less than its denominator. If the numerator is increased by 4 and the denominator is increased by 5, the new fraction becomes equivalent to 4/5. what is the original fraction?
Let n = numerator
d = denominator
n = d - 1
[tex]\frac{d - 1}{d}[/tex]
[tex]\frac{d - 1 + 4}{d + 5}[/tex] = [tex]\frac{4}{5}[/tex]
[tex]\frac{d + 3}{d+ 5}[/tex] = [tex]\frac{4}{5}[/tex]
cross multiply
5(d + 3) = 4(d + 5)
5d + 15 = 4d + 20
d = 5
n = d - 1
5 - 1 = 4
original fraction 4/5

What are the first five terms of the sequence given by the formula an = 4n + 1?
Answer:
5,9,13,17,21
Step-by-step explanation:
We can the values in "n"
a(1)=4(1)+1
a(1)=5
a(2)=4(2)+1
a(2)=9
a(3)=4(3)+1
a(3)=13
a(4)=4(4)+1
a(4)=17
a(5)=4(5)+1
a(5)=21
As you can see, each value consecutively increases by 4, this is also known as the common difference (d).
Given the following kite find:
Answer:
50 degrees
Step-by-step explanation:
in a kite the diagonals are perpendicular and the smallest one divide it in two isosceles triangles. This mean that if the see at the top one we have that the two angles of its base are both 40 degree
a triangle has the sum of interior angles that is 180 degrees
180 - 80 = 100 degrees
the height of a isosceles triangle is also its bisector
a bisector divides an angle in two congruent angles, so we have
1: 100/2 = 50 degrees
Answer:
50 degrees because 40 + 90 + 50 = 180

solve for x in each exponential equation. Round off answers to four decimal places.
Answer:
0.6875
Step-by-step explanation:
24.5 = 3.2⁴ˣ
To get the exponent out of its exponent form, we need to take the ln of both sides:
ln(24.5) = 4x · ln(3.2) - divide both sides by ln(3.2)
[tex]\frac{ln(24.5)}{ln(3.2)}[/tex] = 4x - divide both sides by 4
x = 0.6875
Suppose it takes you 14 hour to drive to the movie theater at a rate of 40 mph. Your friend lives closer to the movie theater than you do. Which inequality represents the distance d (in miles) that your friend lives from the movie theater?
A. d < 10
B. d > 10
C. d > 40
D. d < 160
Answer: (d)
Step-by-step explanation:
Given
It takes 14 hours with 40 mph to reach the theatre
so, the distance traveled is given by
[tex]\Rightarrow d_1=40\times 14\\\Rightarrow d_1=560\ \text{miles}[/tex]
It is given that d is the distance from theatre to friend's house
So, d must be less than [tex]d_1[/tex] i.e.
[tex]d<d_1[/tex]
So, the most appropriate option out of the given is option (d) as d must be less than 560 and it is possible that it maybe less than 160.
Answer:
I believe you meant 1/4 instead of 14... it would be d. If you meant 14 then it would be 560 but there would be no answer choice.

A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £4.80 and the normal price of a jumper is £14.60.
How much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate?
Answer:
The cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.
Step-by-step explanation:
Since a clothes shop has some special offers, for which T-shirts are buy one get one free and jumpers are 3 for 2, and the normal price of a T-shirt is £ 4.80 and the normal price of a jumper is £ 14.60, to determine how much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate, the following calculation must be performed:
4 T shirts = 2 + 2
4.80 x 2 = 9.60
5 jumpers = 2 (+1) + 2
4 x 14.60 = 58.40
Therefore, the cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.

Which expression is equivalent to 2 (t - 4) +12
Answer:
1st one I hope this helped!
Step-by-step explanation:
Answer:
2t - 7
Step-by-step explanation:
We have the expression 2(t - 4) + 1 and are asked to see which is the equivalent.
To solve, we need to first get rid of the parenthesis, which is done by distributing the number outside of the parenthesis to the numbers inside of the parenthesis :
2(t - 4) + 1
(2 * t) - (2 * 4) + 1
2t - 8 + 1
Combine like terms :
2t - 7

The probability of drawing a blue
marble from a bag containing
these marbles is į
If you replace the marble each time,
predict how many times a blue marble
will be chosen out of 50 draws.
[?] times
Enter
Answer:
25 times
Step-by-step explanation:
From the question:
Number of :
Yellow = 2
Red = 3
Blue = 5
P(blue) = required outcome / Total possible outcomes = 5/ 10 = 1/2
If marble is drawn with replacement :
Number of times a blue marble is drawn from 50 trials :
P(blue marble) * 50
1/2 * 50
= 25 times
Evaluate the six trigonometric ratios for ø.
I need sin, cos, tan, csc, sec, and cot please.
Trigonometry.
Answer:
See below
Step-by-step explanation:
First off, the missing side is c=√(17²-8²)=15
sinø=opposite/hypotenuse=15/17
cosø=adjacent/hypotenuse=8/17
tanø=opposite/adjacent=15/8
cscø=hypotenuse/opposite=1/sinø=1/(15/17)=17/15
secø=hypotenuse/adjacent=1/cosø=1/(8/17)=17/8
cotø=adjacent/opposite=1/tanø=1/tanø=1/(15/8)=8/15
In order to complete a large job, 1000 workers were hired, just enough to complete the job on schedule. All the workers stayed on the job while the first quarter of the work was done, so the first quarter of the work was completed on schedule. Then 100 workers were laid off, so the second quarter of the work was completed behind schedule. Then an additional 100 workers were laid off, so the third quarter of the work was completed still further behind schedule. Given that all workers work at the same rate, what is the minimum number of additional workers, beyond the 800 workers still on the job at the end of the third quarter, that must be hired after three-quarters of the work has been completed so that the entire project can be completed on schedule or before?

13800%The distance between City A and City B is 250 miles. On a certain wall map, this is
represented by a length of 1.5 feet. On the map, how many feet would there be between City C
and City D, two cities that are actually 450 miles apart?
Answer:
Step-by-step explanation:
1.5 feet x
====== = ======
250 miles 450
Multiply both sides by 450
1.5 * 450 x
====== =
250 miles
x = 2.7 feet
1 foot = 12 inches
0.7 foot = x
x = 12 * 0.7
x = 8.4 inches
Answer
Either 2.7 feet
or 2 feet 8 inches.

Branson Creek Middle School has decided to make fitness a key message to their students in the upcoming school year. As a result, they will be participating in a national fitness program. To participate, they must randomly select 15 students in the 5th grade and record their exercise time each day. The data (in minutes) are shown.
85, 80, 76, 78, 82, 88, 80, 80, 110, 85, 85, 82, 83, 88, 76
Describe the distribution of the data.
Determine the median and mean of the data.
Which measure better represents a typical value in the data set? Explain.
Answer:
data from minimum to maximum :
76 76 78 80 80 80 82 82 83 85 85 85 88 88 110
n= 15 , so the median is X8 = 82 minutes
mean =
(76+76+78+80+80+ 80 +82+ 82+ 83+ 85+ 85+ 85 +88 +88+ 110) / 15 = (1,258)/15 = 83.87 minutes
in order to get higher standard its better use mean as a typical value.

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan had a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. What is the probability that Nathan is allergic to penicillin and the test predicts it?
A.
0.005
B.
0.015
C.
0.245
D.
0.735
Answer: C. 0.245
Step-by-step explanation:
(100-75)%=25% chance of not having the same allergy
25% x 98% = 0.25 x 0.98 = 0.245
