Answer:
The other length is 60m.
Step-by-step explanation:
If you look at the shape of a parallelogram, you will see that a parallelogram has two parallel sides. So, if the total perimeter is 220m, then 50m and 50m together would be 100m, so 220- 100= 120m left to fill in both sides left. so, 120÷2= 60m. 60m is the other length.
There is a pair of parallel sides in the following shape.
6, 7 and 5

12. If you buy a bag of pretzels ($0.75 per bag) and a Pepsi ($1.25) every weekday at work from a vending machine, how much do you spend on the vending machine products over the course of a year (52 weeks)
0.75 + 1.25 = $2 everyday
Since there are 5 weekdays:
5 x 2 = $10 a week
Since there are 52 weeks in a year:
10 x 52 = $520 a year!
Kat is painting the edge of a triangular stage prop with orange paint. The lengths of the edges of the triangle are (3x-4) feet, (x2-1) feet, and (2x-15) feet. What is the perimeter Of the triangle if x =4
The perimeter of the triangle is 16 feet
What is the perimeter of a triangle?The perimeter of a triangle refers to the calculation of the total distance bounded by the triangle or around the triangle.
Perimeter of a triangle = (3x - 4) + (x² - 1) + (2x - 15)
Perimeter of a triangle = 5x + x² - 20
If x = 4Perimeter of a triangle = 5(4) + (4)² - 20

At the local pet store, zebrafish cost $2.10 each, and neon tetras cost $1.95 each. if ernesto bought 13 fish for a total cost of $26.70 not including tax, how many of each type of fish did he buy?
Answer:
zebrafish: 9neon tetras: 4Step-by-step explanation:
The numbers of zebrafish and neon tetras can be found by writing an equation relating the numbers of each to their total cost.
__
setupLet z represent the number of zebrafish Ernesto bought. Then the number of neon tetras is (13 -z), and the total cost of the purchase was ...
2.10z +1.95(13 -z) = 26.70

The explicit formula is [tex]a_{n-1} = 256 * 0.5^{n-1[/tex] and the sum of the first 25 terms is approximately 512
The explicit formulaThe given parameters are:
[tex]a_0 = 256[/tex]
[tex]a_{n +1} = 0.5a_n[/tex]
Set n = 0
[tex]a_1 = 0.5a_0[/tex]

How to find side of a right triangle?The sides of a right triangle can be found as follows:
using trigonometric ratio,
sin 60 = opposite / hypotenuse
sin 60 = y / 12
cross multiply
y = 12 sin 60
y = 10.3923048454
y = 10.4 units
Therefore,

Here we have a right triangle.
x is the adjacent cathetus to the shown angle, and y is the opposite cathetus. We can see that the hypotenuse measures 12.
Then using trigonometric relations we get:
y = sin(60°)*12 = 10.39x = cos(60°)*12 = 6So we conclude that x measures 6 units and y measures 10.39 units.

The rectangle with:
The volume of (2a³ + a² - 2a - 1) ft³, a > 4 ftThe length > breadth > heightTo find(i) the dimensions(ii) the area of the floorSolution(i)Factorize the volume expression
2a³ + a² - 2a - 1 = 2a³ - 2a + a² - 1 = 2a(a² - 1) + (a² - 1) = (2a + 1)(a² - 1) = (a - 1)(a + 1)(2a + 1)If a > 4, then:
a - 1 > 4 - 1 ⇒ a - 1 > 3a + 1 > 4 + 1 ⇒ a + 1 > 52a + 1 > 2*4 + 1 ⇒ 2a + 1 > 9Since the longest dimension is the length, it is

ii) Area of floor > 45 ft²
Step-by-step explanation:
Volume of a rectangular prism
[tex]\textsf{V}=lbh[/tex]
where:
l is the lengthb is the breadthh is the heightGiven:
[tex]\sf V=(2a^3+a^2-2a-1)\:\:ft^3, \quad where\:a > 4\:ft[/tex]Part (i)
To find expressions for the 3 dimensions of the tank, factor the expression for Volume.
Using the Factor Theorem, if V(x) = 0 then (a - p) is a factor:
[tex]\implies \sf V(1)=2(1)^3+(1)^2-2(1)-1=0[/tex]
[tex]\implies \sf V(-1)=2(-1)^3+(-1)^2-2(-1)-1=0[/tex]
Therefore (a - 1) and (a + 1) are factors:
[tex]\implies \sf 2a^3+a^2-2a-1=(a-1)(a+1)(2a+p)[/tex]
(where p is a constant to be found)
To find the value of p, expand:
[tex]\implies \sf 2a^3+a^2-2a-1=2a^3+pa^2-2a-1[/tex]
and compare coefficients:
[tex]\implies \sf a^2=pa^2 \implies p=1[/tex]
Therefore:

WHAT IS THE CONSTANT AND WHY
Answer:
6
Step-by-step explanation:
The constant is the number that's all by itself with no variable.
x is the variable. It can vary (change) as you use different values for x.
There are four terms here in the expression in your question they are separated by the plus or minus signs.
2 and 4 are exponents. 3 and 5 are coefficients.
x^4 is a fourth degree term. 3x^2 is a second degree term. 5x is a first degree term. The whole expression is 4th degree because the highest exponent is 4.
But the 6 is all by itself. 6 is the constant.
Find the 24th term of the sequence:
11, 16, 21, . . .
Answer:
126
Step-by-step explanation:
The difference between the first two terms of this sequence is 5 (16 - 11 = 5). The difference between the second and third terms of this sequence is also 5 (21 - 16 = 5).
So, we can assume that the difference between each term in this sequence is 5. To get from the first term (11) to the second term (16) we had to add 5 once. (or, add 5 x 1 [time])
To get from the first term (11) to third (21), we had to add 5 twice
(or, add 5 x2)
*repeated addition, such as 5+5+5 is the same thing as multiplication. If we are adding 5 three times, we will get the same outcome as 5 x 3.
So, to get from the first term (11) to the 24th term, we will have to add 5 23 times, or 5 x 23
5 x 23 = 115
11 + 115 = 126
Making 126 the 24th term of the sequence
