the perimeter of a rectangle is 260cm the length is 50 less than its width. find its dimensions
Answers
The dimensions of the rectangle is found as: (b = 90 cm) and (l = 40 cm
).
What is defined as the perimeter of the rectangle?The perimeter (P) of such a rectangle has been the total length of all of its sides. A rectangle does have two equal lengths as well as two equal widths because its opposite sides are equal. The perimeter of a rectangle is calculated as follows: perimeter = length + length + width + widthLet 'l' be the length of the rectangle.
Let 'b' be the width of the rectangle.
then,
Perimeter = 2(l + b)
The given value of the perimeter = 260 cm.
The length is 50 less than the width.
Thus, l = b - 50.
Put the values in the formula;
260 = 2( b - 50 + b)
Simplify the equation;
260 = 4b - 100
4b = 360
b = 90 cm
Put the value of b in the length;
l = b - 50
l = 90 - 50
l = 40 cm
The dimension are estimated as; (l = 40 cm) and (b = 90 cm).

Shane earns $8 per hour babysitting and $6 per hour walking dogs. He also earns tips for each job. Last week Shane spent 2 more hours walking dogs than babysitting. He received $12 in tips for babysitting and
$10 in tips for dog-walking. Shane earned the same total amount for each job.
Write an equation to represent the situation. Use the variable h to represent the number of hours Shane spent babysitting
Answers
The equation to represent the situation is given as $2h -$10 = 0
We have been given that
Money earned by Shane for babysitting = $8 per hour
Money earned by Shane for walking dogs = $6 per hour
Let the number of hours spent by Shane be h hours
Tips she received for babysitting = $12
Tip she received for walking dogs = $10
Total amount earned by Shane for babysitting = $8*h + $12
Also Shane worked two more hours for walking dogs then the amount will be = 2*$6 = $12
Total amount earned by Shane for walking dogs = $6*h + $12 + $10
= $6h + $22
As she earned the same total amount of job the equation will be given as
$8h + $12 = $6h + $22
$2h -$10 = 0

Solve (8×5)÷4×5 step by step
Answers
Answer:
50
Step-by-step explanation:
Apply PEMDAS to this problem
8 × 5 = 40
Now you are left with: 40÷4×5
You then use PEMDAS from left to right from here
So 40 ÷ 4 would be 10, and now you are left with 10 × 5, which would be 50.
Firstly,you would have to to do bracket first, so it will be 8 times 5 which is equal to 40. After this you would divide by 4,so it will be 40 divided by 4 which is equal to 10, after applying this you would have to multiply 10 by 5 which is equal to 50.

You have $175.29 in a savings account. You deposit an additional $48.75. How much more do you need to save to buy the cell phone?
Price: $249.99
Include the steps
Answers
Answer:
Step-by-step explanation:
So in your account you got $175.29
Then you deposit mean increase the amount of money in your account by $48.75
So: 175.29+48.75 = 224.04
The price is $249.99
So: 249.99 - 224.04 = $25.95
You need to save $25.95 in order to buy your cell phone
To buy the cellphone of worth $249.99, additional $25.95 are required.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
The price of cellphone = $249.99
The amount in saving account = $175.29
Additional amount deposit in account = $48.75
Total amount in account after deposit = 175.29 + 48.75 = 224.04
Since, the price of cellphone is $249.99
And the amount in account = 224.04
So the more amount required = 249.99 - 224.04 = 25.95
To buy the cell phone $25.95 are required.

Write an equation in standard form of a line that is parallel to y=4x-3 and passes through the point (7, 10).
Answers
The equation of a line that is parallel to y=4x-3 and passes through the point (7, 10) is 4x - y = 18.
What is the equation of a line that is parallel to y=4x-3 and passes through the point (7, 10)?Given that;
Equation of line: y = 4x - 3Point: ( 7,10 )First, we determine the slope of the line using the slope intercept form.
y = mx + b
m is slope and b is y-intercept.
y = 4x - 3
Comparing with the slope intercept form equation,
Slope m = 4
Now, to determine the the equation of line parallel, the slopes must equal.
We find the line using the point slope formula.
y - y₁ = m(x - x₁)
Plug in m = 4, x₁ = 7, y₁ = 10 and simplify.
y - 10 = 4(x - 7)
y - 10 = 4x - 28
-10 + 28 = 4x - y
4x - y = -10 + 28
4x - y = 18
Therefore, the equation of a line that is parallel to y=4x-3 and passes through the point (7, 10) is 4x - y = 18.

Write a polynomial function of minimum degree in standard form with real coefficients whose zeros and their multiplicities include those listed
2(multiplicity 2) 5+i (multiplicity 1)
Answers
The polynomial function will be y = (x⁴-14x³+70x²-144x+104)
2 and 5+i are the roots of the given polynomial and the multiplicity of 2 and 5+i are 2 and 1 respectively.
Thus, the general form of the polynomial will be given as:
y = (x-2)² (x-(5+i)) (x-(5-i)) [as (5-i) is conjugate of (5+i)]
y = (x²+4-4x) (x-5-i) (x-5+i)
y = (x²-4x+4) (x²-5x+xi-5x+25-5i-xi+5i-i²)
y = (x²-4x+4) (x²-10x+25+1) [as i²= -1]
y = (x²-4x+4) (x²-10x+26)
y = (x⁴-10x³+26x²-4x³+40x²-104x+4x²-40x+104)
y = (x⁴-14x³+70x²-144x+104)
Thus, the polynomial is y = (x⁴-14x³+70x²-144x+104)

Find log[tex]\frac{x^2\sqrt{z} }{y^3}[/tex]
Answers
Using some logarithmic properties, we will see that the solution of the logarithmic equation is 10.5
How to find the value of the logarithm?
Here we have some properties that you need to remember.
log(A*B) = log(A) + log(B)
log(A/B) = log(A) - log(B)
log(Aⁿ) = n*log(A)
Then we can rewrite our equation as:
[log(x²) + log(√z)] - log(y³)
Now, remember that a square root is equal to an exponent of 0.5, then:
[log(x²) + log(√z)] - log(y³) = 2*log(x) + 0.5*log(z) - 3*log(y)
Now we can replace the logarithms by the given values:
2*log(x) + 0.5*log(z) - 3*log(y)
2*7 + 0.5*5 - 3*2 = 10.5

In geometry, variables often appear in problems related to perimeter, area and volume. Typical problems provide you with some precise measurements and ask you to find out an unknown measurement, or variable.
Determine which formula you need. For example, if you're working with the area of a triangle, you need to know that area equals one half the base times the height, or A=1/2bh.
Plug the known values into the formula. Using the area of the triangle example, assume you know that the area is 100 square inches and the base is 20 inches. When you plug these values into the formula, you get 100=1/2 (20h). The height of the triangle is the variable.
