Answer:
107°
Step-by-step explanation:
By definition of a triangle, the ∑ of all angles within the triangle = 180°
It is given that two angles measurements are 44 and 29. Set the equation:
180 = 44 + 29 + x
First, simplify. Combine like terms:
180 = (44 + 29) + x
180 = x + 73
Next, isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other. Subtract 73 from both sides of the equation:
180 (-73) = x + 73 (-73)
x = 180 - 73
Subtract:
x = 180 - 73
x = 107
x = 107° is your answer.

What is the value of 3ab + c when a = 0.32, b = 0.45, and c = 7.2?
Answers
Answer:
7.632
Step-by-step explanation:
When solving this equation, you need to substitute the number equal to a where the a is in the equation, along with the b and c. So since a=0.32, then I would put that where the a is in 3ab+c. Same goes with the other letters.
a = 0.32
b = 0.45
c = 7.2
3ab+c
3(0.32)(0.45)+7.2 *Multiply the 3 to 0.32
0.96(0.45)+7.2 *Multiply the 0.96 to 0.45
0.432+7.2 *Add
7.632

A certain radioactive substance decays from 100000 grams to 1000 grams in 34 days. What's it's half-life ?
Answers
Answer:
Half life of the radioactive element is 5 days.
Step-by-step explanation:
Formula to get the final amount after the radioactive decay in 't' days,
[tex]A_t=A_0e^{-\lambda t}[/tex]
Here [tex]A_0[/tex] = Initial amount
λ = Decay constant
t = duration of decay
[tex]A_t[/tex] = Final amount
[tex]1000=100000e^{-\lambda(34)}[/tex]
0.01 = [tex]e^{-34\lambda}[/tex]
ln(0.01) = [tex]\text{ln}(-e^{34\lambda}})[/tex]
-4.6052 = -34λ
λ = 0.13544
Since, λ = [tex]\frac{\text{ln}(2)}{t_{\frac{1}{2}}}[/tex]
[tex]t_{\frac{1}{2}}=\frac{\text{ln}2}{0.13544}[/tex]
= 5.11
≈ 5 days
Therefore, half life of the radioactive element is 5 days.

Cross multiply
49(x+5) = 14(9x+1)
49x + 245 = 126x + 14

-77x = -231
x = -231/-77
x = 3

Answers
Complete question :
Picture relating to the question is attached below.
Answer:
1 / 3
Step-by-step explanation:
The Theoretical probability of an event is defined as :
P(event) = required outcome / Total possible outcomes
Based on the picture of the attached spinner below :
P(red) :
Required outcome = number of red partitions = 2
Total possible outcomes = total Number of partitions = 6
Hence,
P(Red) = 2 / 6 = 1/3
The local newspaper has letters to the editor from 50 people. If this number represents 4% of all of the newspaper's readers, how many readers does the newspaper have?
Answers
Answer:
[tex]1250[/tex]
Step-by-step explanation:
Let the number of people that are readers of the newspaper be [tex]x[/tex]
[tex]50[/tex] people represents [tex]4\%[/tex] of all the reader of the newspaper.
This means
[tex]\dfrac{4}{100}\times x=50[/tex]
[tex]\Rightarrow x=50\times\dfrac{100}{4}[/tex]
[tex]\Rightarrow x=1250[/tex]
So, the number of readers the newspaper has is [tex]1250[/tex].

A pen will be randomly selected from the drawer. Then another pen will be randomly selected
from the drawer. What is the probability that a blue pen will be selected both times
Answers
Answer:
1/15
Step-by-step explanation:
Probability of 1st selection being blue = 3/10
Probability of 2nd selection being blue (if the 1st blue is not replaced) = 2/9
multiply: 3/10 x 2/9 = 1/15

Ten baseballs and four ping-pong balls cost $46. One baseball costs one dollar more than two ping-pong balls. Find the cost of one baseball and the cost of one ping-pong ball.
Answers
Answer:
1 baseball cost $4
1 ping pong cost $1.5
Step-by-step explanation:
let the cost of baseball be b and the cost of ping pong be p
10 baseballs = 10b
4 ping pong = 4p
Adding both gives total $46
10b + 4p = 46 •••••••••(i)
baseball costs 1 dollar more than 2 ping pong
b = 2p + 1 •••••••(ii)
Substitute ii into i
10(2p + 1) + 4p = 46
20p + 10 + 4p = 46
24p = 46-10
24p = 36
p = 36/24
p = $1.5
b = 2p + 1
b = 2(1.5) + 1
b = 3 + 1 = $4

20% of the girls in class have blonde hair. 16 girls do not have blonde hair. How many total students
Answers
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.

A leopard is running with a velocity of 3 m/s. it then accelerates at 2 m/s² for 4 seconds.
use the formula:
v = u + at
to work out the final velocity of the leopard.
please can people reply and help me thank you
Answers
Using the formula:
v = u + at
Here s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
In this case, u = 3m/s, a = 2m/s^2, t = 4s and we want to find final velocity, v, s, v = u + at
v = 3 + 2(4) = 11m/s

Explanation:
Part A.
1. You have provided an estimate of 600 minutes per month.
__
2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.
__
Part B.
1. Table 2.
See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.
__
2. Rate of Change and Slope (m)
a) Adding a minute adds $0 to the cost
b) The rate of change (m) is 0/1 = 0 (dollars per minute)
__
3. Initial value (b)
a) The plan costs $24.00 when no minutes are used.
b) The initial value (b) is 24.
__
4. Equation of the line
a) Filling the found values of m and b into the equation of the line, we have ...
y = mx + b
y = 0x + 24
y = 24 . . . . . . simplified
__
Part C.
Table 3 can be found in the second attachment.
The b in each case is the value from the Monthly Cost column of Table 1.
The m in each case is the value from the Cost per minute column of Table 1.
The equation is found by copying the values of m and b into y = mx + b.
The number in the last column is found by multiplying the minutes (x) by m, then adding b. For example, your cost for Plan 5 (BELL) is ...
y = 0.10x + 10
y = (0.10)(600) +10 = 60 +10 = 70
