Work out the area of a rectangle with base, b = 34mm and perimeter, P = 86mm.
Answer:
306mm²
Step-by-step explanation:
the height h = 86/2 -34 = 43-34=9mm
the area = 34×9= 306mm²
Answer: (I am assuming this is 2D?)
Two bases together: 34 * 2
68
Two lengths together is p - two bases:
18
Individual length:
9
Area is base times length
9 * 34
306mm

Answer:
$321562.50
Step-by-step explanation:
Exponential growth can be modeled by the formula [tex]y = a(1+r)^{x}[/tex] , with y representing the final value, a being the starting value, r being the growth rate, and x being the number of time intervals passed.
To figure out the rate, we must use the values given from the months we have data of. Our starting value is 60,000 , ending value is 105,000 , and given that monthly sales are given, we can assume that sales grew exponentially each month. There were 4 years, or 48 months, that the store had to grow. Our formula is thus
[tex]105000 = 60000(1+r)^{48}\\[/tex]
To solve for r, we can first divide both sides by 60,000 , then put each side to the power of 1/48, resulting in
[tex]105000/60000 = (1+r)^{48}\\1.75 = (1+r)^{48}\\\\1.75^{1/48} = 1+r[/tex]
Since we know our rate, and there are 8 years/96 months between January 2005 and January 2013, we can make our starting value 105,000 , plug (1.75)^(1/48) for r and 96 for x in [tex]y = a(1+r)^{x}[/tex], and go from there.
Our final value is then
[tex]y = 105000(1.75^{1/48})^{96}\\y = 105000(1.75^{2})\\y = 321562.5[/tex]. We were able to turn 1.75^(1/48)^(96) into 1.75² using the exponent rule stating that x^y^z = x^(y*z)
solve for the missing sidebof the triangle shown in the figure
Answer:
∠B = 74°
a ≈ 14.5 inches
c ≈ 11.4 inches
Step-by-step explanation:
The given parameters of triangle ΔABC are;
∠A = 62.2°, ∠C = 43.8° and side [tex]\overline{AB}[/tex] = b = 15.8 in
By sine rule, we have;
[tex]\dfrac{a}{sin(\angle A)} = \dfrac{b}{sin(\angle B)} = \dfrac{c}{sin(\angle C)}[/tex]
[tex]a = {sin(\angle A)} \times \dfrac{b}{sin(\angle B)}[/tex]
By angle sum property, we have;
∠B = 180° - (∠A + ∠C)
∴ ∠B = 180° - (62.2° + 43.8°) = 74°
∠B = 74°
[tex]\therefore {a} = {sin(62.2^{\circ})} \times \dfrac{15.8}{sin(74^{\circ})} \approx 14.5[/tex]
a ≈ 14.5 in.
[tex]c = {sin(\angle C)} \times \dfrac{b}{sin(\angle B)}[/tex]
[tex]\therefore {c} = {sin(43.8^{\circ})} \times \dfrac{15.8}{sin(74^{\circ})} \approx 11.4[/tex]
c ≈ 11.4 in.

Eliminate the x in the following system of equations. What is the result when you add the two equations?
Answer: -7y = 21
explanation:
x+y=2;3x−4y=27
Step: Solve x+y=2 for x:
x+y+−y=2+−y (Add -y to both sides)
x=−y+2
Step: Substitute −y+2 for x in 3x−4y=27:
3x−4y=27
3(−y+2)−4y=27
−7y+6=27 (Simplify both sides of the equation)
−7y+6+−6=27+−6 (Add -6 to both sides)

Find the median of the data.
The number of girls per classroom.
11, 3, 1, 12, 5, 3, 2
Median: [?] girls
oto
Answer:
3
Step-by-step explanation:
To find the median, first we have to put the data in ascending order:
1, 2, 3, 3, 5, 11, 12
The median is the middle number. In this case, that is 3.
The median of the data "The number of girls per classroom" which has values as 11, 3, 1, 12, 5, 3, 2 is 3.
To find the median of the given data, we first need to arrange the numbers in ascending order:
1, 2, 3, 3, 5, 11, 12
The median is the middle value when the data is arranged in ascending order. In this case, since the total number of data points is odd (7 data points), there is one middle value. The median is the fourth value in the ordered list, which is 3.
The median is a measure of central tendency that represents the middle value in a dataset. It is often used to describe the typical or central value of a set of data and is particularly useful when dealing with skewed distributions or outliers.
In this case, the median of 3 tells us that, when sorted in ascending order, the middle value of the number of girls per classroom is 3, which gives us an indication of the central tendency of the data.

Given the building layout for Store A, Store B, Store
C, and Store D, what portion of the shared $6000
security costs should be apportioned to Store B if store A is 2500ft^2, store B is 625ft^2, store C is 625^2, and store D is 2500ft^2
Answer:
$600
Step-by-step explanation:
2500+625+625+2500=6250
625/6250=.10 or 10%
6000 x .10=600
Store B should be apportioned $600 of the shared $6000 security costs.
To apportion the shared $6000 security costs to each store based on their square footage, we need to calculate the total square footage of all the stores and then determine the proportion of each store's square footage to the total square footage.
[tex]Total square footage = 2500ft^2 (Store A) + 625ft^2 (Store B) + 625ft^2 (Store C) + 2500ft^2 (Store D)[/tex]
[tex]Total square footage = 6250ft^2[/tex]
Now, let's calculate the proportion of Store B's square footage to the total square footage:
[tex]Proportion of Store B = Square footage of Store B / Total square footage\\Proportion of Store B = 625ft^2 / 6250ft^2[/tex]
Now, find the proportion in decimal form:
[tex]Proportion of Store B = 625 / 6250\\Proportion of Store B = 0.1[/tex]
To determine the portion of the security costs for Store B, multiply its proportion by the total security costs:
Portion of security costs for Store B = Proportion of Store B * Total security costs
[tex]Portion of security costs for Store B = 0.1 * $6000\\Portion of security costs for Store B = $600\\[/tex]
Therefore, Store B should be apportioned $600 of the shared $6000 security costs.

Answer:
either 0 or 8, see the step by step for rationale pending the actual question
Step-by-step explanation:
two parallel lines will never intersect.
if it is mean to find the number of 90 degree angles of the two parallel lines and the perpendicular lines, the answer would be 8.
if two lines are perpendicular think of a + sign. there are four angles to make 360 degree so each must be 90 (and the definition of perpendicular).
since there are two parallel lines that intersection happens twice. so 8

A booster club paid for pizzas for an end of season party. They paid $13 for each pepperoni pizza and $11 for each plain pizza. The club bought a total of 18 pizzas for the party and paid a total of $212. Drag and drop the numbers to the boxes to create an equation which models this situation if x = the number of pepperoni pizzas and y = the number of plain pizzas bought.
Answer:
13x + 11y = 212
Step-by-step explanation:
total cost of purchasing an item = unit cost x total units purchased
total cost of purchasing pepperoni pizza = 13 × x = 13x
total cost of purchasing plain pizza = 11 × y = 11y
total cost of purchasing both items = total cost of purchasing pepperoni pizza + total cost of purchasing plain pizza
- 13x + 11y = 212
