Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.
Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet
Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet
Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet

Answer:
a) BE = 5; DE = 6; EF = 4
b) ∠EFC ≅ ∠DA.F ≅ ∠BDE or b = e = f = i
Step-by-step explanation:
Each short segment is the same length as the marked one it is parallel to.
E is the midpoint of BC, so BE = EC = 5.
ADEF is a parallelogram, so DE = A.F = 6.
D is the midpoint of AB, so AD = DB = 4. ADEF is a parallelogram, so ...
EF = AD = 4
__
As we have noted, AB║EF and DE║A.F, so corresponding angles and alternate interior angles are congruent. b = e = f = i
2 Sam is a manager in an office.
She wants to buy 14 new chairs.
Each chair costs £73
Sam will also be charged 20% VAT on the cost of the chairs.
Sam has £1200 to buy the chairs.
Is £1200 enough to buy the 14 chairs?
Answer:
14 X 73 = 1022
1022/100 X 120 = 1226.4
1226.40 - 1200 = 26.40
No Sam does not have enough she is 26.40 short.

What is the rate of change of the linear function that has a graph that passes through the points (1, 15) and (–2, 3)?
Only 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, . , -, and / are allowed in your answer. Answers that are mixed numbers must be entered as an improper fraction or decimal.
Answer:
4
Step-by-step explanation:
Rate of change is just slope, based on what I know.
Given 2 points : (x1, y1) and (x2, y2)... The slope would be [tex]\frac{y_{2}-y_{1} }{x_2-x_{1}}[/tex].
So for this problem we need to find the slope:
(1,15) and (-2,3) are the points. To find slope we do [tex]\frac{3-15}{-2-1}[/tex]. This simplifies into [tex]\frac{-12}{-3}[/tex].This then simplifies into 4.The rate of change is 4 based on my work.

Key skills needed are: Triangle similarity, multiplication, proportions, subtraction
1) We first find that Triangle BCD is similar to triangle ACE. This is because they both have 1 right angle, and both share Angle BCD. Therefore, the other two angles are also the same measure.
2) Based on the statement above, 6/9 = 8/CE (CE just means the length of CE)
3) Solve this by cross multiplying -
[tex] \frac{6}{9} = \frac{8}{ce} [/tex]
This means that 6(CE) = 8(9)
4) Multiply it out: 6(CE) = 72
5) Divide by 6 and get CE = 12 cm.
6) Then use base time height to find the area of both triangles.
7) For triangle BCD: 6(8)/2 = 6(4) = 24 square centimeters
8) For Triangle ACE: 9(12)/2 = 9(6) = 54 square cm
9) To find the area of ABDE, you would subtract the are of triangle ACE by the area of triangle BCD
10) This is 54 - 24 = 30 square cm.

The constant of proportionality is 2.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have [y] varies directly with [x] and y doubles then x.
The general equation of a straight line can also be used to represent proportional relationship when [c] = 0.
y = mx + c
y = mx + 0
y = mx
m = y/x
where [m] is constant of proportionality.
A/C to question -
y = 2x
Here, the constant of proportionality is 2.
Therefore, the constant of proportionality is 2.

what is the slope of the line that passes through (-5,0) and (-5,5)
Answer:
m=undefined
Step-by-step explanation:
the formula for slope (m) is (y2-y1)/(x2-x1)
here are the given points: (-5,0) and (-5,5)
we can label the points:
x1=-5
y1=0
x2=-5
y2=5
now substitute into the equation
m=(5-0)/(-5--5)
m=(5-0)/(-5+5)
m=5/0
m=undefined
the slope is undefined, because you cannot divide by 0
What percentage would the wand need to have exactly a 50% chance of winning
the wizard standoff?
Answer:
What percentage would the wand need to have exactly a 50% chance of winning the wizard standoff?
a;50
I need the answer and how to solve this
Answer:
50
Step-by-step explanation:
Since 140° is on the outside, the angle next to it would be 40°.
Also a triangle = 180°
40° + 90° = 130°
180° - 130° = 50°
Thus meaning x = 50°
Answer:
x = 50°
Step-by-step explanation:
- the angle at the top is shown as a right angle so it is 90°
-the 140° angle and the angle next to it are 180° together so let's name the other angle z
z+140=180
z=180-140=40°
- a triangle's angles in total have 180°
x+y+z= 180°
x+90°+40°=180°
x+130 =180
x= 180-130 = 50°

Answer: The fourth set of sides
Step-by-step explanation:
For a set of side lengths to form a right triangle, they have to satisfy the Pythagorean theory [tex](a^{2} +b^{2} =c^{2} )[/tex]
First set of sides
a = 7.5 b = 18 c = 21.5
[tex]a^{2} +b^{2} =c^{2}\\7.5^{2} +18^{2} =21.5^{2} \\56.25 + 324 = 462.25\\380.25 \neq 462.25[/tex]
Second set of sides
a = 7.5 b = 19.5 c = 21.5
[tex]a^{2} +b^{2} =c^{2} \\7.5^{2} +19.5^{2} =21.5^{2} \\56.25 + 380.25 = 462.25\\436.5 \neq 462.25[/tex]
Third set of sides
a = 18 b = 19.25 c = 21.5
[tex]a^{2} +b^{2} =c^{2} \\18^{2} +19.5^{2} =21.5^{2} \\324 + 380.25 = 462.25\\704.25 \neq 462.25[/tex]
Fourth set of sides
a = 7.5 b = 18 c = 19.5
[tex]a^{2} +b^{2} =c^{2} \\7.5^{2} +18^{2} =19.5^{2} \\56.25 + 324 = 380.25\\380.25 = 380.25[/tex]

Write the word sentence as an inequality. Then solve the inequality.
The product of −2 and a number x is greater than 30.
An inequality is
.
The solution of this inequality is
.
Answer:
-2(x)>30
An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
x<-15
Step-by-step explanation:
-2(x)>30 means to divide -2 on both sides which is -15.
x>-15
Next you switch the inequality because you multiplied by a negative:
x<-15

what is 150 % of 32 ?
i already know that it’s 48, i just really need to know how “i” got it.
Answer: 48
=================================================
Explanation:
The keyword "of" means multiply
150% converts to the decimal form 1.5; you move the decimal point two spots to the left to go from percent form to decimal form
Putting those two facts together lead to...
150% of 32 = 1.5*32 = 48
----------------
Another approach:
x% = x/100
150% = 150/100 = 1.5
150% of 32 = 1.5*32 = 48
The last step is identical as before, but the conversion of 150% is slightly different this time.
------------------
Yet another approach:
100% of anything is itself
So 100% of 32 is 32
The extra 50% means we take half of 32 to get 16. Then we add that onto the 32 to get 16+32 = 48

Can a right triangle be formed using these squares?
25, 144, 169
Answer:
Yes
Step-by-step explanation:
The two smaller squares have a sum of 169 which is the value of the larger square.
a^2 + b^2 = c^2
25 + 144 = 169
It can be done. Notice the figure below shows you how to arrange the squares to give the answer of a^2 + b^2 = c^2
Answer:
Yes, if we take the square roots of 25, 144 and 169 (5, 12, 13)
Not by using those measures as is (sides of a triangle with 25, 144 and 169).
Explanation:
A right triangle is a triangle with an angle of 90 degrees, and the side facing that angle of 90 degrees is called an hypotenuse.
The hypotenuse measurement squared is equal to the squared measurements of the other two sides:
c² = a² + b²
And those squares do verify the equation:
169 = 144 + 25
So, that's a rectangle (right) triangle, with sides measuring 5, 12 and 13.
Hope this helps :)
