Nico is saving money for his college education. He invests some money at 7%, and $1600 less than that amount at 6%. The investments produced a total of $177 interest in 1 yr. How much did he invest at each rate?
Answer:
Step-by-step explanation:
177=.07x+.06(x-1600)
177=.13x-96
273=.13x
x=2100
Which means that the amount invested 2100 at 7% and 500 at 6%

How to find the width of a rectangle given length?
No links, i am not able to view them!
Answer:
Step-by-step explanation:
there are several ways. if u have angels use cos or sin therom. if u have a 90 degree angle use The Pythagorean Theorem. send it completely
Answer:
Before one can solve for the width of a rectangle(the value of the area or perimeter must be given and the length)
Using the area
Length = l
Width =w
Area = a
a = l × w ; a = lw
w = a/l
using perimeter(p)
p = 2(l+w)
p/2 = l+w
p/2 - l = w
w = p/2 -l

Rewrite the quadratic function from standard form to vertex form.
f(x)x^2+6x-5
Answer:
[tex]y = {(x + 3)}^{2} - 14[/tex]
Step-by-step explanation:
The original equation
[tex] f(x) = {x }^{2} + 6x - 5[/tex]
vertex form
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
solve for the x coordinate of the vertex, h
[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]
substitute -3 back into the original equation to solve for y
[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]
substitute h and k values into the vertex form
a = 1 So we can omit it
[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]

Eric traveled to three cities on a single highway. The distance from his original location to the first city was 100 miles more than the distance from the first city to the second city. The distance from the second city to the third city was 10 miles less than the distance from the first city to the second city. If the distance from his original location to the first city and the distance from the second city to the third city were the same, what was the total distance Eric traveled?
Answer:
Well think about it, the key words there are more than and less than so if he traveled let's say from his house until the first city that's 100 miles for the first one and then they say that he traveled 10 miles less than the distance from the first city until the second city. The total distance is 280 because if you read the very last sentence it says that from the original distance from the first city is about 100 miles and then it says if the the distance from the second city to the third city was the same that means that the equation goes like this: (90*2)+100 and in order to get this correctly you must do P.E.M.D.A.S which is parenthesis, exponents, multiplying, dividing, adding and subtracting so there you go.

Math expert please provide the product in standard form
Please answer the questions in order NO LINKS please thanks
Answer:
Step-by-step explanation:
Sum: 6 * 10^-4 + 1.5*10^-4 = 7.5 * 10^-4
Difference: 6 * 10^-4 - 1.5 * 10^-4 = 4.5 * 10^-4
Product: 6*10^-4 * 1.5 * 10^-4 = 9 * 10^-8
Quotient: 6*10^-4/1.5 * 10^-4 = 4
Notice the answers, because they give you the rules.
When adding exponents and rationales, if the powers are the same then the rationales merely add.
Same rule applies to subtraction. Retain the powers and subtract the rationales.
When multiplying the rationales multiply, but the rationales add. they don't stay the same.
When dividing, the rationales divide and the powers subtract -- numerator minus denominator

The length of a rectangle is 4ft longer than it’s width. If the perimeter of the rectangle is 68ft, find it’s length and width.
Answer:
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.

Who can solve these three ??
Answer:
1) x = 9
2) y = 16
3) y = -1
Step-by-step explanation:
Do PEMDAS in reverse.
For every equation, your goal is to seperate the variable (x,y, or whatever letter) by itself.
1) 2x-7 = 11
Add 7 to both sides.
2x = 18
Divide both sides by 2.
x = 9
2) [tex]\frac{3}{4}y = 12[/tex]
Divide both sides by 3/4 (which turns into multiplying by 4/3).
Left side
[tex]\frac{3}{4}x * \frac{4}{3}\\\\\frac{3}{4}x * \frac{4}{3} = \frac{3*4}{4*3}x\\1x\\x[/tex]
Right side
[tex]12*\frac{4}{3}\\\\\frac{12}{1} *\frac{4}{3}\\\\ \frac{12}{1} *\frac{4}{3} = \frac{12*4}{1*3}\\\\\frac{48}{3} \\16[/tex]
3) 9(y+3) = 18
Remember do PEMDAS in reverse.
Divide both sides by 9.
y+3 = 2
Subtract both sides by 3.
y = -1
Find the value of x.
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
so,
x + 12 + 2x - 29 + x + 5 = 180
4x - 12 = 180
4x = 192
x = 48
Kaya started with the number 92. After multiplying by a power of 10, her number increased to 920,000. What power of 10 did Kaya multiply her original number by to get an answer of 920,000? Explain the reason for this solution
The new number has 4 zeros so the power was 4
Answer: 4
Answer:
4
Step-by-step explanation:
kaya started with 92
then multiplied it by
[tex]10 ^{x} [/tex]
[tex]92 \times {10}^{x} [/tex]
[tex]92 \times {10}^{x} = 920000[/tex]
divide both sides by the coefficient of
[tex] {10}^{x} [/tex]
[tex] {10}^{x} = \frac{920000}{92} [/tex]
[tex] {10}^{x} = 10000[/tex]
[tex] {10}^{x} = {10}^{4} [/tex]
since they both have the same numbers we can cancel the two 10
therefore:
x = 4
