Answer:
L = length, W = width and P = perimeter
L = 3W + 18
Perimeter = 116 = 2(L + W) , i.e. L + W = 58
Now substitute
3W + 18 + W = 58
4W = 40
W = 10
L = 48
Step-by-step explanation:
If the perimeter of a rectangle is 116. The length is 18 more than 3 times the width. The length and width of the rectangle will be 48 and 10 units.
What is a rectangle?It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral. The area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that, the perimeter of a rectangle is 116. The length is 18 more than 3 times the width. Fine the dimensions
L = length, W = width and P = perimeter
L = 3W + 18 -------- (1)
Perimeter = 116
Perimeter = 2(L + W)
L + W = 58
Put the value in equation 1,
3W + 18 + W = 58
4W = 40
W = 10
L = 48
Thus, if the perimeter of a rectangle is 116. The length is 18 more than 3 times the width. The length and width of the rectangle will be 48 and 10 units.

please show working out

Answer:
a = 92° , b = c = 143°
Step-by-step explanation:
a and 88° are same- side interior angles and sum to 180° , that is
a + 88° = 180° ( subtract 88° from both sides )
a = 92°
b and 37° are same- side interior angles and sum to 180° , then
b + 37° = 180° ( subtract 37° from both sides )
b = 143°
b and c are corresponding angles and are congruent , then
c = b = 143°
kaylin buys a greeting card for $3.79. she then buys 4 postcards that all cost the same amount. the total cost is $5.11. how much is each postcard. show your work
i need the answer today
Answer:
Step-by-step explanation:
Givens
Greeting Card = 3.79
Total Cost = 5.11
Post cards = x
Equation
Total Cost = Greeting Card + 4x
Solution
Substitute the gives into the equation
5.11 = 3.79 + 4x Subtract 3.79 from both sides
5.11 - 3.79 = 3.79 - 3.79 + 4x Combine
1.32 = 4x Divide by 4
1.32/4 = 4x/4
x = 33
Each post card costs 0.33 dollars

What is the ordered pair in the solution set of 0. 5x-2y=3
Answer:
See Below
Step-by-step explanation:
The left side of the equation HAS TO BE GREATER THAN 3
So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.
A:
0.5x - 2y
0.5(-2) -2(0.5) = -2
NO
B:
0.5x - 2y
0.5(2) -2(1) = -1
NO
C:
0.5x -2y
0.5(2) -2(-1) = 3

Step-by-step explanation:
This is because , you have the number 75, and dividing that by 3 is 25, but since our number is 0.75, that means we are adding the 2 zeros from our 300 and add it on to be to 0.0025, this won’t work in some situations.

Anja simplified the expression StartFraction 10 x Superscript negative 5 Baseline Over Negative 5 x Superscript 10 Baseline EndFraction to StartFraction 15 Over x Superscript 15 Baseline EndFraction. What mistake did Anja make? She divided the exponents instead of subtracting them. She divided the coefficients instead of subtracting them. She subtracted the coefficients instead of dividing them. She subtracted the exponents instead of dividing them.
The mistake that Anja made during the simplification of the considered expression is given by: Option C: She subtracted the coefficients instead of dividing them
What are coefficients?Constants who are in multiplication with variables are called coefficients of those variables.
For example, in [tex]10x^2[/tex] we have 10 as coefficient of [tex]x^2[/tex]
Those variables who have got no visible coefficient has 1 as their coefficient. Thus, [tex]x^2[/tex] has got its coefficient as 1. It is true since 1 multiplied with any number is that number itself.( [tex]x^2 = 1 \times x^2[/tex] )
What are some basic properties of exponentiation?If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c[/tex]
For the considered situation, the expression that Anja is simplifying is:
[tex]\dfrac{10x^{-5}}{-5x^{10}}[/tex]
Anja simplified it to [tex]\dfrac{15}{x^{15}}[/tex]
She performed operations with variable 'x' correctly since
[tex]\dfrac{x^{-5}}{x^{10}} = \dfrac{1}{x^5} \times \dfrac{1}{x^{10}} = \dfrac{1}{x^{15}}[/tex]
But coefficients will also get divided. Instead of dividing 10 by -5, she subtracted them (as 10 - (-5) = 10 + 5 = 15)
This was her mistake.
The correct simplification would be: [tex]\dfrac{10x^{-5}}{-5x^{10}} = \dfrac{10}{-5} \times \dfrac{x^{-5}}{x^{10}} = -2 \times \dfrac{1}{x^{15}} = \dfrac{-2}{x^{15}} = -2x^{-15}[/tex]
Thus, the mistake that Anja made during the simplification of the considered expression is given by: Option C: She subtracted the coefficients instead of dividing them

A triangle has two sides of length 1 and 14. What is the largest possible whole-number length for the third side?
Answer:
14
Step-by-step explanation:
The triangle inequality is usually expressed as ...
a +b > c
for any permutation of a, b, c.
Here, that would mean ...
1 + 14 > c
c < 15
The largest whole-number value that the third side (c) can have is 14.
_____
Additional comments
Some authors write the triangle inequality as ...
a +b ≥ c
If you use that version, the longest side could be 15. Such a "triangle" would look like a line segment, and have zero area.
__
We can also check the shortest length:
c +1 > 14
c > 13
The smallest whole-number value for the shortest side is also 14. That is, the only triangle with whole-number side lengths of 1 and 14 will be an isosceles triangle with two sides of length 14.
