The diagram represents the floor of a museum. The figure is made up of a rectangle and a triangle.
What is the area of the floor?
Enter your answer in the box.
______ ft2 I'll but the link for the pic
The figure is formed of a rectangle and a triangle
The rectangle has dimensions:length=38ft and width=20ft
The triangle has dimensions:base=33ft and height=9ft
Area of rectangle=length*width of rectangle
Area of triangle=[tex] \frac{1}{2} [/tex]*base*height
Area of figure= area of rectangle + area of triangle
Area=length*width+[tex] \frac{1}{2} [/tex]*base*height
Area=38*20 + [tex] \frac{1}{2} [/tex]*33*9
Area=760+[tex] \frac{1}{2} [/tex]*297
So we have, Area=760+[tex] \frac{297}{2} [/tex]
Or, Area=760+148.5
Area=908.5
Area of the floor=908.5[tex] ft^{2} [/tex]

a rectangular prism has a volume of 144 cm3. the base is a square with a length of 4 cm. what is the height of the prism
Answer:
9 cm
Step-by-step explanation:
The volume is given by the formula ...
V = LWH
Filling in the given numbers, you have ...
144 cm^3 = (4 cm)(4 cm)H
H = (144 cm^3)/(16 cm^2) = 9 cm
The height of the prism is 9 cm.

Marianne has been collecting donations for her biscuit stall at the school summer fayre. There are some luxury gift tins of biscuits to be sold at £5 each, normal packets at £1 each, and mini- packs of 2 biscuits at 10p each. She tells Amy that she has received exactly 100 donations in total, with a collective value of £100, and that her stock of £1 packets is very low compared with the other items. Amy wants to work out how many of each item Marianne has. Show how she can do it.
Number of luxury gift tins of biscuits L sold is 18.
Number of mini- packs of 2 biscuits M sold is 80.
Number of normal packets N sold is 2.
Step-by-step explanation:Let L, M, N represent the number of Luxury, Mini, and Normal packets sold.
Total earned by selling luxury gift tins of biscuits = 5L
Total earned by selling normal packets = £1N
Total earned by selling 2 biscuits at 10p = 0.1M
Marianne tells Amy that she has received exactly 100 donations in total:
Equation becomes:
[tex]L+N+M=100[/tex] .... (1)
total earning is £100, so another equation becomes:
[tex]5L+N+0.1M=100[/tex] .......(2)
Given is that stock of £1 packets is very low compared with the other items:
so, N<L and N<M
Putting y = 0 in equation 1 and 2
[tex]L+M=100[/tex] or [tex]L=100-M[/tex] .....(3)
[tex]5L+0.1M=100[/tex] ......(4)
Replacing L by 100-M in the equation 4
[tex]5(100-M)+0.1M=100[/tex]
[tex]500-5M+0.1M=100[/tex]
4.9M=400
M=81.63
As, L=100-M
[tex]L=100-81.63=18.37[/tex]
L=18.37
We can round L and M to 18 and 81 respectively and solve for N from 1 and 2 equations.
[tex]L+M+N=100[/tex]
=>[tex]18+N+81=100[/tex]
=>[tex]N=1[/tex]
[tex]5(18)+N+0.1(81)=100[/tex]
[tex]90+N+8.1=100[/tex]
=> N=1.9
We will repeat the same process with N = 2 and get the following result.
Number of luxury gift tins of biscuits L sold is 18
Number of mini- packs of 2 biscuits M sold is 80
Number of normal packets N sold is 2

A retired couple invested $6000 in bonds at a simple interest rate of 5.1%. At the end of one year, how much interest did they receive on their investment? Please show your work.
The retired couple received $306 in simple interest on their investment of $6000 at a rate of 5.1% for one year.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the simple interest earned by the retired couple on their investment of $6000 at a rate of 5.1% for one year
we can use the formula: I = P × r × t
where I is the simple interest,
P is the principal (the amount invested),
r is the interest rate (as a decimal), and
t is the time period (in years).
Plugging in the given values, we get:
I = 6000 × 0.051 × 1
I = 306
Therefore, the retired couple received $306 in simple interest on their investment of $6000 at a rate of 5.1% for one year.

Which pair of expressions is equivalent using the Associative Property of Multiplication? (3 points) 5(3a ⋅ 4) = 15a ⋅ 20 5(3a ⋅ 4) = (3a ⋅ 4) ⋅ 5 5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4 5(3a ⋅ 4) = 5 ⋅ 3a ⋅ 4 6
Answer:
5(3a ⋅ 4) = (5 ⋅ 3a) ⋅ 4
Step-by-step explanation:
The Associative Property is applied to two types of operations: addition and multiplication. This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.
In this sense, the associative property for the sum is mathematically given by:
[tex](x+y)+z=x+(y+z)[/tex]
and for the multiplication by:
[tex](xy)z=x(yz)[/tex]
Now, let:
[tex]x=5\\y=3a\\z=4[/tex]
Using the Associative Property of Multiplication:
[tex](xy)z=x(yz)\\\\Replacing\hspace{3}the\hspace{3}values\\\\(5\cdot 3a)\cdot4=5(3a\cdot 4)[/tex]

What is the period of y = 3cot(4x - 3pi)
The period of y = 3cot(4x - 3pi) is π/2 units.
The period of the function y = 3cot(4x - 3π) is calculated as the reciprocal of the absolute value of the parameter in front of x.
To find the period, identify the coefficient of x, which is 4 in this case. The period is then given by 2π/|4| = π/2.
Therefore, the period of the given function y = 3cot(4x - 3π) is π/2 units.

what direction is 45 degrees in clockwise from due east?
A direction of 45 degrees clockwise from due east would put you in the South-East quadrant of a compass or geometric plane.
Explanation:When discussing directions in terms of degrees, it's commonly understood with the idea of a compass rose or a unit circle in mind. Here, 'Due East' is represented as 0 or 360 degrees. A clockwise rotation would mean we are moving in a positive direction.
Therefore, if you start from Due East which is 0 degrees and rotate 45 degrees in the clockwise direction, you would end up in the south-east direction. This is because in the coordinate system, the +x direction is East and moving in the clockwise direction, the next quadrant would be the South-East quadrant. So, 45 degrees clockwise from due east would be considered as South-East direction on a compass rose or geometrically on a plane if you are looking at it in terms of degrees on a circle.

Answer:
Perpendicular bisector theorem
Step-by-step explanation:
Perpendicular bisector theorem: if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment's endpoints.
So, if segment ST is the perpendicular bisector of segment RV, then, by perpendicular bisector theorem, any point in segment ST (like S) is equidistant from points R and V, in consequence, segments RS and SV are equal.

a copper alloy that is 40% copper is to be combined with a copper alloy that is 80% copper to produce 120 kilograms of an alloy that is 70% copper. how many kilograms of each alloy must be used? please work it out
After setting up and correcting a system of equations, the student needs to use 30 kg of the 40% copper alloy and 90 kg of the 80% copper alloy to create 120 kg of a 70% copper alloy.
To solve this problem, we need to set up a system of equations. Let x be the amount of 40% copper alloy needed, and y be the amount of 80% copper alloy needed.
First, we have the total weight equation:
x + y = 120 kg (the final alloy's total weight)
Next, we have the copper content equation:
0.40x + 0.80y = 0.70 × 120 kg (the final alloy's copper content)
Now, let's solve this system of equations:
Address the second equation: 40x + 80y = 8400
Express x in terms of y: 40x = 8400 - 80y
Divide by 40: x = 210 - 2y
Substitute x in the first equation: (210 - 2y) + y = 120
Solve: 210 - y = 120, y = 90 kg
Finally, substitute the value of y back into x = 210 - 2y: x = 210 - 2 imes 90 = 210 - 180 = 30 kg
So, we need 30 kg of the 40% copper alloy and 90 kg of the 80% copper alloy.
