Nico was stunned when he opened the mail.Here was a check for $332.50 this is the interest he earned on his investment.One year ago Nico had been given 5,000.His parents made him put it in the bank and save it for college,but the said he could keep the interest it earned each year.A portion of his money is deposited in a high rate account that earned 8% annual interest.The rest is in a regular account that earned 3% this year.Both accounts pay simple interest computed at the end of the year.How much of Nicos money was invested in each account.
Answer:
Investment A = 3650
Investment B = 1350
Step-by-step explanation:
Given that:
Total interest earned = 332.50
Total Principal invested = 5000
Investment A:
Rate = 8%
Time = 1 year
Principal = a
Interest earned = 0.08a
Investment B:
Rate = 3%
Time = 1 year
Principal = b
Interest earned = 0.03b
a + b = 5000 ____(1)
0.08a + 0.03b = 332.50 - - - (2)
From (1)
a = 5000 - b
Into (2)
0.08(5000 - b) + 0.03b = 332.50
400 - 0.08b + 0.03b = 332.50
400 - 0.05b = 332.50
-0.05b = - 67.5
b = $1350
a = 5000 - b
a = 5000 - 1350
a = $3650

HELP.
can someone help me with this please
Answer:
Step-by-step explanation:
The wording on this is not the best. It sounds like the 1 zero has even multiplicity (that's because of where the modifier is). On top of that it has an odd power. You could try this. y =x*(x^2+1)^2
The problem is not with the power. It gives x^5. The problem is with the multiplicity of the one place where it crosses. (X^2 + 1) does factor, but it gives a complex root. I'm not sure that's allowed. However, it is the best I can do.
the sum of two positive integers $a$ and $b$ is $1001$. what is the largest possible value of $\gcd(a,b)$?
The two integers 143m, 143n = a, b have only the factor of 143 in common.....and it is the g c d of both given , two positive integers of a and b is = 1001 factors 0f 1001is = 7 x 11 x 13 So.....143 is the greatest proper divisor of 1001.This means, that we have 143( m + n) = 143m + 143m = a + b = 1001, where ( m + n) = 7 and,
m + n are two positive integers whose sum = 7,
they are relatively prime to each other.
Therefore, these two integer 143m, 143n = a, b have only the factor of 143 in common.....and it is the g c d of both
An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Integers come in three types: Zero (0) Positive Integers (Natural numbers) Negative Integers (Additive inverse of Natural Numbers)
An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. A few examples of integers are: -5, 0, 1, 5, 8, 97, and 3,043.

Which statement is not true for the parabola who equation is y= 2x^2- 12x +29
- The parabola opens upward
- The vertex is ( -3, 11)
- The axis of symmetry is x= 3
- The parabola contains the point ( 1, 19)
Again, thank q sm for helpingggg <3 I will give brainliest and Thanks hehe
Answer:
I just graphed it in desmos for you UvU
The second answer is false. The vertex is not (-3, 11). The vertex is (3, 11). I can see that the parabola has a point of (1, 19), and the parabola opens upward, as well as has an axis of symmetry; x = 3.
Hope that helps
A rectangular lot is 120 meters long and 85 meters wide.
Give the length and width of another rectangular lot that has the same perimeter but a smaller area.
The length and width of another rectangular lot that has the same perimeter but a smaller area will be 140 and 65m
How to illustrate the information?It should be noted that perimeter is calculated as:
Perimeter = 2(Length + Width)
Perimeter = 2(120 + 85)
Perimeter = 410m
Therefore, the length and width of another rectangular lot that has the same perimeter but a smaller area will be 140 and 65.
The area will be:
= 140m × 65m
= 9100m²
This is smaller than (120 × 85) = 10200m².

The angle between the generator and the central axis of a double-napped cone is 50°. Which conic section is formed when a plane intersects the central axis at 50°?
circle
ellipse
parabola
hyperbola
Answer:
Parabola
Step-by-step explanation:
A parabola will be formed when a plane intersects the central axis at 50°
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
The angle between the generator and the central axis of a double-napped cone is 50° and a plane intersects the central axis at 50°
Ф = ∅
Where Ф is the angle between the vertical axis and plane and
∅ is the angle between the generator and central axis.
When both angles are the same the parabola is formed by the intersection of the plane.
Thus, a parabola will be formed when a plane intersects the central axis at 50°

18 movie goers bought tickets on-line. This represents 30% of the total people going to the same movie. How many people are seeing the movie?
Answer:
60
Step-by-step explanation:
[tex]0.3 \times x =18 \\ x = 18 \div 0.3 \\ x = 60[/tex]
need help Bad!!!!!!!!
Answer:
z=118 y=21
Step-by-step explanation:
for z
since 2 sides of a line should equal 180 degrees, subtract 62 from 180
180-62=118 since z and the side opposite of 62 are congruent so
z=118
for y
62 and [tex]5y-43[/tex] are congruent so set them equal to each other and solve:
[tex]5y-43=62\\5y=105\\\\y=21[/tex]

earth's circumference is roughly 24,900 miles. using this information to calculate the answer to this question. then, use your answer to this question to calculate the answers to the next series of questions. round your answer to three decimal places (for example, 317.284 miles). in order to receive credit you must show your work. to show your work, please type out every number and mathematical function you used to arrive at the answer. how many miles are there in one degree of latitude? show your work. hint: consider that, while we only express latitudes up to 90 degrees (the number of degrees between the equator and the poles), the full circumference of any circle or sphere, (or near-sphere, in the case of the earth) encompasses 360 degrees.
There is a circumference of 69.167 miles per degree of latitude.
How many arc does the Earth comprise by one degree of its latitude?
Firstly, we assume that the earth is a spherical form to simplify calculations as spheres have constant radii of curvature, because the real form of the planet is similar to a oblate spheroid, a kind of ellipsoid. In addition, the circular arc (s), in miles, is directly proportional to the measure of the central angle (θ), in degrees, that is:
s ∝ θ
s = k · θ (1)
Where k is the constant of proportionality, in miles.
Now we eliminate the constant of proportionality and we calculate the circular arc afterwards:
s / 24900 mi = 1° / 360°
s = 1 / 360 × 24900 mi
s = 69.167 mi
There is a circumference of 69.167 miles per degree of latitude.
