Answer:
A
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)
2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)
3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D
4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B
5. After this elimination process, the only remaining answer is C) P(E)=0.9

Dara pinkston Recorded her house and expenses for a month of August mortgage payment was 347.90Insurance $17 Texas $84 electricity $64.40 phone service $33.50 fuel $98.25 water $17.44 in repairs $79.87 .Her monthly take-home pay is 2150 what's her total money coast?
Answers
Answer:
the total monthly cost is $742.36
Step-by-step explanation:
The computation of the total monthly cost is shown below:
= Mortgage payment + insurance + taxes + electricity + phone service + fuel + water + repairs
= $347.90 + $17 + $84 + $64.40 + $33.50 + $98.25 + $17.44 + $79.87
= $742.36
hence, the total monthly cost is $742.36

show that triangle BCD is isosceles
Answers
∠C =36
∠ADB =72°
∠CBD =36°
∠BDC =108°
Explanation:
AB=AD then ∠ABD & ∠ADB must be equal as they share two lines that are equal so ∠ADB=72°
∠A and ∠C must also be equal (AB=BC)
∠A = 180-72-72=36°
So ∠A & ∠C=36°
∠D=180° (straight line)
So if ∠ADC=72
∠BDC=108° (180-72)
A triangle has 180° so in triangle BDC we have 108° and 36°
So remaining angle (∠CBD) =180-108-36
=36°
This tells us that triangle BDC is isosceles as it has two equal angles ∠CBD & ∠C =36°
Step-by-step explanation:
∠BAC = ∠BCA because it is an isosceles triangle
∠ADB = ∠ABD = 72° because it is an isosceles triangle
∠BAD = 180° - 72° - 72° = 36° because the sum of all interior angles in a triangle = 180°
∠BDC = 180° - 72° = 108° because it is supplementary to 72°
∠ABC = 180° - 36° - 36° = 108° because the sum of all interior angles in a triangle = 180°
∠DBC = 108° - 72° = 36° (∠ABC - ∠ABD)
since ∠DBC = ∠DCB, ΔBCD is isosceles

Two trapeziums are similar, thee area of one of the trapezium is 4times that of the other. Determine the ratio of the perimeter & the corresponding side length of the trapezium
Answers
Answer:
The ratio of the perimeters of the two trapezium is 2
The ratio of the corresponding sides of the two trapezium is 2
Step-by-step explanation:
The given parameters in the question are;
Two trapeziums are similar
The area of one trapezium = 4 × The area of the other trapezium
Let, A₁, and A₂ represent the area of the two trapeziums, we have
A₁ = 4 × A₂
∴ A₁/A₂ = 4
Given that ratio of areas = (Ratio of sides)²
Ratio of sides = Ratio of perimeter
∴ Ratio of areas = (Ratio of perimeter)²
Therefore, given that the ratio of the areas of the two trapeziums A₁/A₂ = 4, we have;
Ratio of areas = 4 = (Ratio of sides)²
The ratio of the corresponding sides = √4 = 2
The ratio of the corresponding sides = 2
Ratio of areas = 4 = (Ratio of perimeter)²
The ratio of the perimeter = √4 = 2
The ratio of the perimeter = 2

The ratio of the corresponding sides = √4 = 2
The ratio of the corresponding sides = 2

The ratio of the perimeter = 2

First step: you got to add y to both sides in the math problem Ex: 15x - y + y < 12 + y
Second step: simplify 15x < 12 + y
Third Step: This you got to divide both sides by 15 like this: 15x/15 < 12/15 + y/15
Last and Fourth step: Simplify and thats your answer x < 12 + y/15

Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda. Carla collects 3(5 + 2f) bottles. How many bottles did they collect altogether in terms of f ?
From the question
Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda.
= 2(4f - 3)
= 8f - 6 bottle caps
Carla collects 3(5 + 2f) bottles.
= 15 + 6f bottles
The number of bottles they collected altogether in terms of f is calculated as:
(4f – 3) bottle + 8f - 6 bottle + 15 + 6f bottle
4f - 3 + 8f - 6 + 15 + 6f
= 18f - 6
