Answer:
Down Below
Step-by-step explanation:
b=0.5
g=0.8
1. 3b + 5g = ?
3×0.5+5×0.8=?
1.5+4= 5.5 cm
2. 6(3b+5g) = ?
18b + 30g
18×0.5+30×0.8
9+24= 33 cm
3. 2b + 3g
2×0.5+3×0.8
1+2.4=3.4 cm
4. 7(2b+3g)
14b + 21g
14×0.5+21×0.8
7+16.8= 23.8 cm
5. Add number 2 and 4 together
14b+21g+18b+30g= 32b+ 51g
Take numbers and add them from problems 2 and 4
23.8+33=56.8 cm
Answer:
Step-by-step explanation:
<u>Given Data:</u>
Speed = v = 855 m/s
Distance = S = 2 km = 2000 m
<u>Required:</u>
Time = t = ?
<u>Formula:</u>
v = S/t
<u>Solution:</u>
Rearrange the formula
t = S/v
t = 2000/855
t = 2.34 seconds

Answer: 100

Explanation:
First term
f(1) = 1
which is given to us
We will use the equation f(n+1) = -10*f(n) to generate successive terms after this first term.
---------------
Second term
f(n+1) = -10*f(n)
f(1+1) = -10*f(1) ... plug in n = 1
f(2) = -10*f(1)
f(2) = -10*1 ... replace f(1) with 1 (works because f(1) = 1)
f(2) = -10
Put another way, the second term is -10 times the first term
second term = -10*(first term)
second term = -10*(1)
second term = -10
---------------
Third term
f(n+1) = -10*f(n)
f(2+1) = -10*f(2) ... replace n with 2
f(3) = -10*f(2)
f(3) = -10*(-10) ... replace f(2) with -10 (works because f(2) = -10)
f(3) = 100 which is the answer we want
In other words, the third term is -10 times the second term
third term = -10*(second term)
third term = -10*(-10)
third term = 100
---------------
Summary of the three terms
f(1) = 1
f(2) = -10
f(3) = 100
Each term is found by multiplying the previous term by -10
Answer:
10
Step-by-step explanation:
If J + K = 90 degrees and K = 45 degrees, J has to be 45 degrees.
3x+15=45
-15 -15
3x=30
/3 /3
x=10
5/8 = 0.625 = 62.5%
If 62.5% were glazed then you must find 62.5% of 24.
Equation…
x=0.625(24) = 15
if each costs $0.84 cents plus tax then you will multiply by 15.
15 x .84 = 12.6
The total cost was $12.60
