Answer:
62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So
29+16+17= 62
or if you want to impress then start with the total and subtract each given coin count
74-29-16-17=12
74-12=62
Francois is paid $52 per day for a job that lasts 4 days. He is paid $67 per day for a different job. Francois earned a total of $610. How many days was he paid $67 per day?
Answer:
6 days
Step-by-step explanation:
$52 per day for 4 days: 4 * $52 = $208
Total pay: $610
Pay for remaining days: $610 - $208 = $402
Number of $67/day days: $402/($67/day) = 6 days
Answer: 6 days

Assume that three fifths of the population has long hair and and one tenth of the poulation has blue eyes. What is the probability that a person does not have long but does have blue eyes?
Answer:
1/25
Step-by-step explanation:
If 3/5 have long hair, then 2/5 do not have long hair
So, the probability of no long hair, has blue eyes = 2/5(1/10) = 1/25

you can use the formula of pythagoras theorem to know what of them is wrong
in the first case
-5^2 + 12^2 =169
13^2=169 ( it's a right equation so it can be lengths of right angle tri )
in the second case
_9^2 + 12^2 =225
17^2 not equal 225
so these are the lengths that can't be a right angle triangle
8.35 < 3x +18.75
Pls help
Step-by-step explanation:
8.35 < 3x + 18.75
3x + 18.75 > 8.35
3x > 8.35 - 18.75
3x > -10.4
x > -3.47

How much must be added to each of the three number 1, 11, and 23 so that together they form a geometric progression?
Answer:
49
Step-by-step explanation:
Let the three numbers be a1, a2, a3
Let the number to be added to form a geometric progression = x
a1 = 1 + x ; a2 = 11 + x ; a3 = 23 + x
For a geometric progression :
a2 = a1 * r
a2 = (1+x)r
11+x = (1+x)r - - (1)
r = (11+x) / (1+x) ---(1)
a3 = a2 * r
a3 = (11+x)r
23+x = (11+x)r - - -
r = (23+x) / (11+x) - - (2)
Equate (1) and (2)
(11+x) / (1+x) = (23+x) / (11+x)
(11+x) * (11+x) = (23+x) * (1+x)
121 + 22x + x² = 23 + 24x + x²
121 + 22x + x² - x² - 24x - 23 = 0
98 - 2x = 0
-2x = - 98
x = 98 / 2
x = 49
In one part of a kennel, 5/8 of the 24 dogs are male. In another part of the kennel, 4/5 of the 30 dogs are male.
How many male dogs are in the two parts of the kennel?
Answer:
39
Step-by-step explanation:
The computation of the number of male dogs in the two parts of the kennel is shown below:
In one part, the male dogs are
= 24 × 5 ÷ 8
= 15
In the another part, the male dogs are
= 30 × 4 ÷ 5
= 24
So, the total male dogs is
= 15 + 24
= 39
Factorise the following:
a) x + 3x - 4
b) x - 2x - 3
c) x + 2x - 8
The lines shown below are perpendicular. If the green line has a slope of
2/5 , what is the slope of the red line?
Answer:
-5/2
Step-by-step explanation:
for perpendicularity;
[tex]m1 = \frac{ - 1}{m2} [/tex]
where m1 is first slope
and m2 is second slope
so here, let m1 be green line slope
and m2 be red line slope
thus,
[tex]m2 = \frac{ - 1}{m1} [/tex]
[tex]m2 = \frac{ - 1}{ \frac{2}{5} } = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} = \frac{ - 5}{2} [/tex]

Pls help with #6 pls pls!!!
Answer:
Answers in explanation.
Step-by-step explanation:
Finding angle 1:
52 + angle 1 = 180
angle 1 = 128
Finding angle 2:
128 (angle 1) + angle 2 = 180
angle 2 = 52
Finding angle 5:
52 + 47 + angle 5 = 180
angle 5 = 81
Finding angle 3:
angle 2 + angle 3 + angle 5 = 180
52 + angle 3 + 81 = 180
angle 3 = 47
Finding angle 4:
angle 3 + angle 4 = 180 OR angle 4 + 47 = 180
47 + angle 4 = 180
angle 4 = 133

Answer:
D=1 or just 1, i dont get what the question is
Step-by-step explanation:
Answer:
d=1
Step-by-step explanation:
Move 7 to the other side by subtracting 7 on both sides:
2d+7-7=9-7
The equation now looks like this:
2d=2
Divide 2 on both sides:
2d/2=2/2
The equation now looks like this:
d=1 which is the answer

Explain the steps of graphing 2x + 4≤ 12.
Answer:
Step-by-step explanation:
First, you want to simplify so the equation would be x+2≤6 or x≤4
Because you are solving for x you want to graph a vertical line on 4.
Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.
