Answer:
5.5%
Step-by-step explanation:
The formula for Simple Interest = PRT
Where
Simple Interest = $115.50
P = Principal = $700
R = Interest rate = ??
T = Time in years = 3 years
$115.50 = $700 × R × 3
R = $115.50/$700 × 3
R = $115.50/$2100
R = 0.055
R = Interest rate = 0.055
We Multiply by 100
= 0.055 × 100
= 5.5%

#2. A field of grass feeds 36 cows for 4 days. How
many days would the same field feed 20 cows?
162 cow-days
Since the initial grass and the grass accumulated over 4 days is equal to 144 cow-days, the initial grass is equal to (144 − 36) or 108 cow-days. Now, to find the answer to the question: in 18 days, the grass accumulation is equal to 18 ∗ 9 or 162 cow-days.
Please consider marking brainliest! :)
Using the principle of proportional relationship, it will take 20 cows 7.2 days.
Setting up the relationship thus :
36 cows = 4 days
Hence, if they eact at the same rate ;
1 cow = 36 × 4 = 144 days
Hence, for 20 cows, it will take;
144 days ÷ 20
= 7.2 days
Hence, 20 cows will feed on the grass for 7.2 days

What is the slope and y-intercept of the function represented by the table
slope =
y-intercept =
Answer:slope = -2/3
Y inter. =7
Step-by-step explanation:
To get the slope= y-y divide x-x which is = 3-5 divide 6-3
= -2/3
So the equation will be :
Y=mx+b
Y=-2/3x+b
Now to get the b which is the yinter. We have to put a “x” and a “y “
Lets put (3,5)
5=-2/3 x (3) +b
5= -2 + b
7=b

Pablo created the bar model and equation after paying a $9.79 lunch bill with a $20 bill.
A bar diagram. The top bar contains 20.00. The bottom bars contain c and 9.79.
20.00 = c + 9.79
What is the value of c, and what does it represent in this problem?
The value is $10.21, and it shows the cost of Pablo’s lunch.
The value is $29.79, and it shows the cost of Pablo’s lunch.
The value is $10.21, and it shows the change Pablo received.
The value is $29.79, and it shows the change Pablo received.
Answer:
The value of "c" represents the amount of change that Pablo will receive
Step-by-step explanation:
If you pay 9.79 in lunch with a 20 dollar bill, you would have 10.21 in change.
Let's use the equation given to us:
20.00 = c + 9.79
now let's subtract 9.97 on both sides of the equation:
20.00 - 9.79 = c + 9.79 - 9.79
we're left with:
10.21 = c
this is how much money we're left with after we pay for lunch, which is the change given to us. Therefore,
c = the amount change Pablo will have after he pays for his lunch
Answer:
C

Given w1 = -2 + 3i and W2 = 4 - 4i, which complex number can be added to Wi to produce wz?
6-i
-6-i
6-7i
-6+7i
Given:
Two complex numbers are [tex]w_1=-2+3i[/tex] and [tex]w_2=4-4i[/tex].
To find:
The complex number that can be added to [tex]w_1[/tex] to produce [tex]w_2[/tex].
Solution:
Let complex number [tex]z=[/tex] is added to [tex]w_1[/tex] to produce [tex]w_2[/tex].
[tex]w_1+z=w_2[/tex]
[tex]z=w_2-w_1[/tex]
On substituting the values, we get
[tex]z=(4-4i)-(-2+3i)[/tex]
[tex]z=4-4i+2-3i[/tex]
Combine like real and imaginary parts.
[tex]z=(4+2)+(-4-3)i[/tex]
[tex]z=6+(-7)i[/tex]
[tex]z=6-7i[/tex]
Therefore, the correct option is C.

Uninhibited growth can be modeled by exponential functions other than A(t) =Upper A 0 e Superscript kt. For example, if an initial population Upper P 0 requires n units of time to triple, then the function P(t)equals Upper P 0 (3 )Superscript StartFraction t Over n EndFraction models the size of the population at time t. An insect population grows exponentially. Complete the parts a through d below.
The question is incomplete. Here is the complete question.
Uninhibited growth can be modeled by exponential functions other than [tex]A(t)=A_{0}e^{kt}[/tex]. for example, if an initial population P₀ requires n units of time to triple, then the function [tex]P(t)=P_{0}(3)^{\frac{t}{n} }[/tex] models the size of the population at time t. An insect population grows exponentially. Complete the parts a through d below.
a) If the population triples in 30 days, and 50 insects are present initially, write an exponential function of the form [tex]P(t)=P_{0}(3)^{\frac{t}{n} }[/tex] that models the population.
b) What will the population be in 47 days?
c) When wil the population reach 750?
d) Express the model from part (a) in the form [tex]A(t)=A_{0}e^{kt}[/tex].
Answer: a) [tex]P(t)=50(3)^{\frac{t}{30} }[/tex]
b) P(t) = 280 insects
c) t = 74 days
d) [tex]A(t)=50e^{0.037t}[/tex]
Step-by-step explanation:
a) n is time necessary to triple the population of insects, i.e., n = 30 and P₀ = 50. So, Exponential equation for growth is
[tex]P(t)=50(3)^{\frac{t}{30} }[/tex]
b) In t = 47 days:
[tex]P(t)=50(3)^{\frac{t}{30} }[/tex]
[tex]P(47)=50(3)^{\frac{47}{30} }[/tex]
[tex]P(47)=50(3)^{1.567}[/tex]
P(47) = 280
In 47 days, population of insects will be 280
c) P(t) = 750
[tex]750=50(3)^{\frac{t}{30} }[/tex]
[tex]\frac{750}{50}=(3)^{\frac{t}{30} }[/tex]
[tex](3)^{\frac{t}{n} }=15[/tex]
Using the property Power Rule of logarithm:
[tex]log(3)^{\frac{t}{30} }=log15[/tex]
[tex]\frac{t}{30}log(3)=log15[/tex]
[tex]t=\frac{log15}{log3} .30[/tex]
t = 74
To reach a population of 750 insects, it will take 74 days
d) To express the population growth into the described form, determine the constant k, using the following:
A(t) = 3A₀ and t = 30
[tex]A(t)=A_{0}e^{kt}[/tex]
[tex]3A_{0}=A_{0}e^{30k}[/tex]
[tex]3=e^{30k}[/tex]
Use Power Rule again:
[tex]ln3=ln(e^{30k})[/tex]
[tex]ln3=30k[/tex]
[tex]k=\frac{ln3}{30}[/tex]
k = 0.037
Equation for exponential growth will be:
[tex]A(t)=50e^{0.037t}[/tex]

1What is the simple interest on #25 000 for 3years at 5% per annum?.
#28 750
#3 750
#2 875
#375
Answer:
3750
Step-by-step explanation:
Simple interest (I) is calculated as
I = [tex]\frac{PRT}{100}[/tex] ( P is the principal, R is rate of interest and T time in years )
Here P = 25000, R = 5 and T = 3 , thus
I = [tex]\frac{25000(5)(3)}{100}[/tex]
= [tex]\frac{375000}{100}[/tex]
= 3750
Justin has a crate that is 8 feet long 2 feet wide and 3 feet tall decide weather each of the crate sizes described below has the same volume as Justin's crate
Complete question is;
Justin has a crate that is 8 feet long, 2 feet wide, and 3 feet tall. Decide whether each of the crate sizes described below has the same volume as Justin’s crate.
a. 9 feet long, 1 foot wide, 4 feet tall
b. 8 feet long, 2 feet wide, 2 feet tall
c. 4 feet long, 4 feet wide, 3 feet tall
d. 8 feet long, 3 feet wide, 3 feet tall
e. 6 feet long, 2 feet wide, 4 feet tall Answer:
Options C & E have the same volume as Justin's crate.
Step-by-step explanation:
We are told Justin has a crate that is 8 feet long, 2 feet wide, and 3 feet tall.
Thus, original volume is;
V_o = 8 × 2 × 3 = 48 ft³
A) For a dimension of 9 feet long, 1 foot wide, 4 feet tall , volume is;
V_a = 9 × 1 × 4 = 36 ft³
B) For a dimension of 8 feet long, 2 feet wide, 2 feet tall, volume is;
V_b = 8 × 2 × 2 = 32 ft³
C) For a dimension of 4 feet long, 4 feet wide, 3 feet tall, volume is;
V_c = 4 × 4 × 3 = 48 ft³
D) For a dimension of 8 feet long, 3 feet wide, 3 feet tall, volume is;
V_d = 8 × 3 × 3 = 72 ft³
E) For a dimension of 6 feet long, 2 feet wide, 4 feet tall, volume is;
V_e = 6 × 2 × 4 = 48 ft³
Looking at all the options, the only ones that given a volume equal to Justin's original volume are options C & E.
common factors of 128 and 192
Answer:
The greatest common factor of 128 and 192 is 64, because 64 is the highest number that is divisible by both numbers.
The greatest common factor of 128 and 192 is 64 because 64 is the highest number that is divisible by both numbers.
What is the greatest common factor?The greatest common factor is the largest positive number which can be divided into given numbers evenly.
In mathematics, the largest positive integer that divides each of the integers is known as the greatest common divisor of two or more integers that are not all equal to zero. The greatest common divisor of two integers is x and y.
Given that the two numbers are 128 and 192. The greatest common factor is the largest number which is divided into both numbers.
128 = 2 x 2 x 2 x 2 x 2 x 2 x 2
192 = 2 x 2 x 2 x 2 x 2 x 2 x 3
The greatest common factor is,
GCF = 2 x 2 x 2 x 2 x 2 x 2
GCF = 64
