Answer: its 31.4 i think cuz if you divide 157 and 5 you get 31.4 in an hour
Step-by-step explanation:
I divided
Answer:
If he bikes 157 miles in 5 hours and we need to know hhwo many miles he can bike in 1 hour, we need to divide
157/5=31.4
Step-by-step explanation:
157 divided by 5
5 fits in 15 3 times
5x3=15
15-15=0
we bring down the 7 and 5 only fits in 7 one time
5x1 is 5 so 7-5 is 2
we add a decimal after 157 and drop it down to creat 20
5x4 is 20 so the answer is 31.4

How many 1/4’s are in 2/3?
Answer:
We'll leave 2/3 as it is and reciprocate 1/4 into 4/1. 2/3 × 4/1 = 8/3 which becomes 2.66. So 1/4 will go into 2/3 2.66 times.

Write down the Inequality for x that is shown in this line.
Answer:
[tex]x>3[/tex]
Step-by-step explanation:
Using the line shown here, we can see that the variable x can takes values greater than 3.
The white circle means that the x can not take this value.
Then, x could be 4, 5, 6, ... and so on.
Putting this information into an inequality form we will have:
[tex]x>3[/tex]
or in interval terms, all the values of x ∈ (3, infinity).
I hope it helps you!

Only hash channel catfish typically was about 0.06 g during the first six weeks of life at weight increase about 10% each day right a exponential model for the weight how much will the catfish gain weight after six weeks
Answer:
3.225 gram
Step-by-step explanation:
Given that :
Initial weight = 0.06g
Rate of increase, r = 10% = 0.1 per day
Weight gain after 6 weeks
For an exponential model. f(x)
f(x) = a(1 + r)^x
Where ; a = initial amount ; r = growth rate ; x = period
Our model becomes :
f(x) : 0.06(1 + 0.1)^x
f(x) = 0.06(1.1)^x
Number of days in 6 weeks = 6*7 = 42 = x
f(42) : 0.06(1.1)^42
= 3.285 gram
Hence, weight gain after 6 weeks :
(3.285 - 0.06) g = 3.225 gram
is 6 greater then 0.8
Answer:
Yup, its greater than 0.8
Answer:
Yes
Step-by-step explanation:
0.8 is less than 1 and 6 is greater than one so 6 is greater than 0.8. :)

Andy is buying a car
he negotiated a 7% decrease on a £6 500 car
he will pay the full balance in 12 equal month payments
calculate the amount paid each month
Answer:
£503.75 per month
Step-by-step explanation:
7% decrease on a £6,500 car
= 7% of 6,500
= 7/100 * 6,500
= 0.07 * 6500
= £455
Amount of the car = £6,500 - £455
= £6,045
he will pay the full balance in 12 equal month payments
Amount paid each month = £6,045/12 months
= £503.75 per month
Answer:
7% decrease on a £6,500 car
= 7% of 6,500
= 7/100 * 6,500
= 0.07 * 6500
= £455
Amount of the car = £6,500 - £455
= £6,045
he will pay the full balance in 12 equal month payments
Amount paid each month = £6,045/12 months
= £503.75 per month

What is the slope of a line parallel to line A?
A. -4/7
B. -7/4
C. 4/7
D. 7/4
Answer:
The answer is C.4/7
Step-by-step explanation:
First of all, parallel lines have the same gradient (slope), so if you find the slope for line A this will be the same slope as the line parallel to it (line A).
Step 1: find any two points from line A.point 1: (0,4) Where, [tex]x_{1} =0[/tex] and [tex]y_{1}=4[/tex]
point2: (-7,0) Where, [tex]x_{2} =-7[/tex] and [tex]y_{2} =0[/tex]
Step2: write the formula of the slope:[tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
Step3: substitute the numbers in the formula:[tex]m=\frac{0-4}{-7-0}[/tex]
Step4: simplify the formula to get the answer to the slope:[tex]m=\frac{-4}{-7}[/tex]
[tex]=\frac{4}{7}[/tex]
So the answer is:C. 4/7
(note: this is the slope of line A and any line parallel to line A)

Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation. a. X + 12 = 20 ( 12,8,20,0) b. P - 4 = 0 (4,-4,8,0) c. 2y - 3 = 7 (0,3,5,7) Plz explain ;)
Answer:
(a) 8
(b) 4
(c)5
Step-by-step explanation:
We are given multiple parts and we need to provide the correct answer among the given options, also we need to prove that rest of the answers are wrong.
(a). X + 12 = 20 ( 12,8,20,0)
X= 20 -12
X= 8, so only 8 is the correct answer and rest are wrong.
Proof: lets take other given options into consideration
X= 12
X+12 =12+ 24 which is wrong because X+12 is already given as 20.
similarly,
X=20
X+12 = 20+12 = 36, which is wrong because X+12 is already given as 20.
X= 0
X+12 = 0+12 = 12, which is wrong because X+12 is already given as 20.
(b). P - 4 = 0 (4,-4,8,0)
P-4 = 0
P= 4, So only 4 will give the correct answer and not the other options.
P= -4 = -4 -4 = -8, which is wrong because P-4 is is already given as 0.
similarly,
P = 8 = 8-4 = 4, which is wrong because P-4 is is already given as 0.
P = 0, 0-4 = -4 , which is wrong because P-4 is is already given as 0.
(c). 2y - 3 = 7 (0,3,5,7)
2y = 7 + 3
2y = 10
y = 5, only 5 will satisfy this given equation and rest will be wrong,
y = 0
2y-3 = 7
2(0) - 3 = 7
-3 = 7 which is not correct as LHS and RHS must be same.
similarly,
y = 3
2y-3=7
2(3) - 3 =7
6-3 = 7
3=7 which is again wrong.
y = 7
2(7) -3 =7
14-3 = 7
11=7, which is wrong.
Therefore the given options for the correct answers is verified and the wrong answers are given as the proof.

Answer:
2 roots this parabola have because it line passes at x - axis.
Please help with number 1 and 4 asap!
Answer:
Total surface area
1) 46cm²
4) 304cm²
Step-by-step explanation:
1) First you need to work out each face on its own, opposites will be the same such as the front and back, top and bottom, side to side, because its a rectangle.
Formula : Base x height
Front/back : 5x3=15 and 15 =30 (added together)
top/bottom : 1x5= 5 and 5 = 10
side/side : 3x1= 3 and 3 = 6
30+10+6=46cm²
4) lets work out the easy ones first using the same formula from question 1 for one surface area but this is a trapezium, which is a irregular quadratical shape so the sides would most liky be different from each other except the front and back.
Top : 5x8=40
bottom : 3x10=30
right side : 12x8=96
Left side : 12x10=120
front/back= 12x3=36 / 2 = 18
Because if u added another side to make it a rectangle then divide by 2 would get the answer or 1/2 x base x height also works.
40+30+96+120+18=304cm²
