Let x be Bob's age. Heather is 5 years younger than Bob. Write an expression for Heather's age.
Answer:
x-5
Step-by-step explanation:
since we don't know bob's age, x will represent it. we know that heather is 5 years YOUNGER than bob.
x (bob's age) - 5 (because that's how many years heather is younger than bob is)

Answer: Adams heart Beats 1,440 more times than Blake’s in 120 minutes.
Step-by-step explanation:
Adam: 74 x 120 = 8,880
Blake: 62 x 120 = 7,440
8,880 - 7,440 = 1,440
Answer:
1440
Step-by-step explanation: you multiply
74 x 120 and 62 x 120
8,880 7,440 then subtract the two
8,880 - 7,740 = 1,440

Determine if both triangles are congruent or not. Label the triangles as SSS, AAS, ASA, SAS, HL, or not enough information.
△ABD and △BCD are congruent as:
∠CBD = ∠ABD (Equal Angles)
BD = BD (Common side)
The 90 degree angle (Common between both triangles)
Therefore
△ABD ≅ △BCD (By AAS)
The diagram is not drawn to scale and it appears misleading since AD appears shorter than DC. However, the smaller triangles are congruent and we can prove it using ASA.
The tickmarks on the angles show we have a pair of congruent angles. The other pair of congruent angles are the two right angles (angle BDC and angle ADB). The pair of congruent sides are DB = DB. We use the reflexive property here. The sides are between the congruent angles mentioned. So we'll use ASA and not AAS.
-------------
Extra info:
We can't use SSS because we only have info about one pair of sides. SAS won't be used either for the same reason. HL = hypotenuse leg, and it applies to right triangles only. We don't have any info about the hypotenuse of either triangle, so we can't use this either.A ball is dropped from a height of 100 cm. The rebound heights to the nearest centimeter are 60, 36, 22, .... What is the total distance the ball will travel both up an down?
Answer:
400 cm
Step-by-step explanation:
Given that:
Initial height at which ball was dropped = 100m
Rebound heights to the nearest cm = 60, 36, 22...
First we find the rebound percentage x;
x% * 100m = 60
100x % = 60
x = 60%
Hemce, we need to calculate the rebound velocities which aren't given:
0.6 * 22 = 13.2 = 13cm
0.6 * 13 = 7.8 = 8cm
0.6 * 8 = 4.8 = 5cm
0.6 * 5 = 3cm
0. 6 * 3 = 1.8 = 2 cm
0.6 * 2 = 1.2 = 1cm
The total distance the ball travels UP and DOWN :
(100 + 2(60) + 2(36) + 2(22) + 2(13) + 2(8) + 2(5) + 2(3) + 2(2) + 2(1))
= 400 cm

Mabel, Adeline and Charlie share 34500ft2 of land Mabel ownes 26%of the land area and Adeline Owens 47% of the land area . What is the land area that charlie owns ?
Answer:
Charlie owns 9,315 ft2 of the land area
Step-by-step explanation:
There are 34,500 ft2 of land shared between Mabel, Adeline, and Charlie.
Mabel owns 26% of the land area, that is:
26*34,500 ft2 / 100 = 8,970 ft2
Adeline owns 47% of the land area, or:
47*34,500 ft2 / 100 = 16,215 ft2
The land owned by Mabel and Adeline is: 8,970 ft2 + 16,215 ft2 = 25,185 ft2
Since the total area land is 34,500 ft2, Charlie owns:
34,500 ft2 - 25,185 ft2 = 9,315 ft2
Charlie owns 9,315 ft2 of the land area

Find the sum: 2.234 + 0.01
Answer:
The sum of 2.234 and 0.01 is 2.244.
Step-by-step explanation:
The 0.01 is in the hundredths place, so just add 1 to the number in the hundredths place of 2.234, to make it 2.244.
Alice walks along a road which can be modeled by the equation y=6x, where (0,0) represents her starting point. When she reaches a certain point A, she turns right, so that she is traveling perpendicular to the original road, until she stops at the point (333,0). What was the point A where Alice turned?
9514 1404 393
Answer:
(9, 54)
Step-by-step explanation:
The first road has a slope of 6 on its graph. So, the perpendicular road will have a slope of -1/6, the negative reciprocal of the slope of the original road. Translating that from y=-1/6x the the right by 333 units, the equation of the second road is ...
y = -1/6(x -333)
The point where Alice turned is the point of intersection of these two equations:
y = 6xy = -1/6(x -333)Substituting for y, we have ...
6x = -1/6(x -333)
36x = -x +333 . . . . . multiply by 6, eliminate parentheses
37x = 333 . . . . . . . . add x
x = 9 . . . . . . . divide by 37
So, the point where Alice turned is ...
(x, y) = (9, 6·9)
(x, y) = (9, 54)

Can the union of two sets have a solution of a null set? Why or why not?
Answer:
Yes, the union of two sets have a solution of a null set.
Step-by-step explanation:
Bit transmission errors between computers sometimes occur, where one computer sends a 0 but the other computer receives a 1 (or vice versa). Because of this, the computer sending a message repeats each bit three times, so a 0 is sent as 000 and a 1 as 111. The receiving computer "decodes" each triplet by majority rule: whichever number, 0 or 1, appears more often in a triplet is declared to be the intended bit. For example, both 000 and 100 are decoded as 0, while 101 and 011 are decoded as 1. Suppose that 6% of bits are switched (0 to 1, or 1 to 0) during transmission between two particular computers, and that these errors occur independently during transmission.(a) Find the probability that a triplet is decoded incorrectly by the receiving computer.(b) Using your answer to part (a), explain how using triplets reduces communication errors.(c) How does your answer to part (a) change if each bit is repeated five times (instead of three)?(d) Imagine a 25 kilobit message (i.e., one requiring 25,000 bits to send). What is the expected number of errors if there is no bit repetition implemented? If each bit is repeated three times?
Answer:
(a) Probability that a triplet is decoded incorrectly by the receiving computer. = 0.010
(b)
(1 – p) = 0.010
(c)
E(x) = 25000 x 0.010
= 259.2
Explanation has given below.
Step-by-step explanation:
Solution:
(a) Probability that a triplet is decoded.
2 out of three
P = 0.94, n = 3
m= no of correct bits
m bit (3, 0.94)
At p(m≤1) = B (1; 3, 0.94)
= 0.010
(b) Using your answer to part (a),
(1 – p) = 0.010
Error for 1 bit transmission error.
(c) How does your answer to part (a) change if each bit is repeated five times (instead of three?
P( m ≤ 2 )
L = Bit (5, 0.94)
= B (2; 5, 0.94)
= 0.002
(d) Imagine a 25 kilobit message (i.e., one requiring 25,000 bits to send). What is the expected number of errors if there is no bit repetition implemented? If each bit is repeated three times?
Given:
h = 25000
Bits are switched during transmission between two computers = 6% = 0.06
m = Bit (25000, 0.06)
E(m) = np
= 25000 x 0.06
= 1500
m = Bit (25000, 0.01)
E(m) = 25000 x 0.010
= 259.2

Jordan earns $15.35 per hour. on Tuesday , Jordan clocked in at 7:45 Am then clocked out for a break at 12:15 am and working until 6:00 pm a.How many hours did Jordan work b.what was his total pay for day
12:45Answer:
Part A: 9 hours 45 minutes
Part B: $126.1575
Step-by-step explanation:
Part A,
From 7:45 to 12:15 is 4 hours and 30 minutes
From 12:45 which he clocked back in to 6:00 is 5 hours and 15 minutes.
4 hours and 30 minutes plus 5 hours and 15 minutes = 9 hours and 45 minutes.
Part B, 9 hours and 45 minutes can be represented as 9.45
And since he gets 15.35 "per" hour shows we can multiply.
15.35 x 9.45 = 126.1575
Therefor he earned 126.15.

Answer:
33/209
Step-by-step explanation:
11*19=209 . 3(11)=33 . 33/209
Given parameters:
Length of the rectangle = [tex]\frac{11}{19}[/tex] mile
Width of the rectangle = [tex]\frac{3}{11}[/tex] mile
Unknown:
Area of the rectangle = ?
Solution:
The area of a rectangle is
Area of rectangle = length x width
= [tex]\frac{11}{19}[/tex] x [tex]\frac{3}{11}[/tex]
= [tex]\frac{3}{19}[/tex]mile²
Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 2.9 × 105 words.
Samuel can type 2.9 × 105 words in
hours and
minutes.
Answer:
Samuel can type 40 words per minute
Step-by-step explanation:.
Then how many hours will it take for him to type 2.6 words times 10 to the power of five words
=> 2.6 words time 10 to the power of 5
=> 2.6 x 10^5
=> 2.6 x 100 000
=> 260 000 words in all.
Now, we need to find the number of words Samuel can type in a hour
=> 40 words / minutes , in 1 hour there are 60 minutes
=> 40 x 60
=> 2 400 words /hour
Now, let’s divide the total of words he need to type to the number of words he can type in an hour
=> 260 000 / 2 400
=> 108.33 hours.

Answer:
700,000
Step-by-step explanation:
Well, [tex]10^{4}[/tex] as we know is 10(10)(10)(10), or 10 multiplied by itself 4 times.
The easiest way to solve this, is knowing that because 10 is being multiplied by itself 4 times, it'll have the outcome of 10000, which has 4 zeroes. This is very good to remember, so I recommend remembering it :) Just like if the question was about [tex]10^{5}[/tex], it would be 100000, which has 5 zeroes.
So now we add on all of those zeroes to 70.
700000 would be your answer because we added on 4 more zeroes.
given;, angle 2 = angle 4. angle 2 = 110
