Simplify the expression
8.8 (3.6d +1)
Answers
Answer:
31.68d + 8.8
Step-by-step explanation:
We have to simplify the expression but with one dillemma. The number 8.8 is outside the parenthesis of 3.6d + 1 and 3.6d + 1 aren't combinable because they aren't like terms.
When we have a problem like 8.8 being out of the parenthesis, we need to distribute 8.8 to both numbers in the parenthesis, or in other terms multiplying.
(8.8 * 3.6d + 1 * 8.8)
31.68d + 8.8

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What could be the coordinates of the other two vertices of the rectangle?
Answers
Answer:
There are two possible solutions for the other two vertices of the rectangle:
(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)
Step-by-step explanation:
Geometrically speaking, the perimeter of a rectangle ([tex]p[/tex]) is:
[tex]p = 2\cdot b + 2\cdot h[/tex] (1)
Where:
[tex]b[/tex] - Base of the rectangle.
[tex]h[/tex] - Height of the rectangle.
Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:
[tex]b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}[/tex]
[tex]b = 5[/tex]
If we know that [tex]p = 18[/tex] and [tex]b = 5[/tex], then the height of the rectangle is:
[tex]2\cdot h = p-2\cdot b[/tex]
[tex]h = \frac{p-2\cdot b}{2}[/tex]
[tex]h = \frac{p}{2}-b[/tex]
[tex]h = 4[/tex]
There are two possible solutions for the other two vertices of the rectangle:
(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Let (applicable to all three lines below)Hard candy = x kg with price $1.60/kgGummy worms = y kg with price $2.20/kgTotal weight = 50 kg with mixed price $1.75/kgRequired equations:
x + y = 50 total weight1.60x + 2.20y = 50*1.75 total price=========================================
Note. It says don't solve but the solution below for those who is interested to know the answer.
Simplify the second equation and solve by substitution x = 50 - y:
1.6(50 - y) + 2.2y = 87.580 - 1.6y +2.2y = 87.50.6y = 7.5y = 7.5/0.6y = 12.5Find the value of x:
x = 50 - 12.5 = 37.5Hard candy = 37.5 kg and gummy worms = 12.5 kg

The washing machine had a selling price of P4,792. It had been marked up by P1,248. What was the cost? What was the mark-up rate?
Answers
Answer:
The cost of the washing machine is P 3,544
The mark-up rate is 35.21%
Step-by-step explanation:
1. We want to calculate the cost
Mathematically, this is the difference between the selling price and the mark up
We have this as;
4,792 - 1,248 = P 3,544
2. Here, we want to calculate the mark-up rate
Mathematically, this is the percentage of mark-up
That is;
mark-up/cost price * 100%
: 1,248/3,544 * 100% = 35.21%

In the mail, you receive a coupon for $5 off for a pair of jeans, which is represented by the function j(x)=x−5. When you arrive at the store, you find that all jeans are 25% off, which is represented by the function s(x)=0.75x. Which of the functions below represents how much you would pay for a pair of jeans, C(x)=s(j(x)) , if you use the coupon first followed by applying the discount from the store? (Do not consider tax.)
A .C(x)=0.75x−5
B .C(x)=0.75(x−5)
C .C(x)=0.75x−x−5
D .C(x)=x−5−0.75
Answers
Answer: B
Step-by-step explanation: The function C(x) = s(j(x)) shows you how to solve it.
First in the parenthesis j(x) so you have to substitute since they told you
j(x) = x-5
Next s(x-5) and s(x-5) = 0.75(x-5) through substitution

Obtuse triangle
Answers
Answer:
That is an obtuse scalene triangle
Step-by-step explanation:
Scalene- has no congruent sides
Obtuse - has an angle that is greater than 90
we can use Pythagorean theorem to confirm this
The Pythagorean theorem states that in an obtuse triangle the hypotenuse squared is greater than the two legs squared added together
so basically [tex]7^2>4^2+5^2\\7^2=49\\4^2=25\\5^2=25\\25+16=41\\49>41[/tex]
therefore it is an obtuse scalene
Answer:
(Choice E) E Scalene triangle and (Choice F) F Obtuse triangle
Step-by-step explanation:
Aside from E, Scalene triangle (as all the sides are of different lengths, we can assume that the angles will also be), the answer can either be B, Isosceles triangle or F, Obtuse triangle, so let's figure that out using the cosine rule! If it is an obtuse triangle, this means Angle ABC is bigger than Angle BAC and Angle BCA. But we can clearly see it is, as it's an Obtuse Triangle is a triangle where 1 angle is bigger than 90 degrees. Let's work out Angles BAC and BCA to find out if the triangle is obtuse or isosceles.
[tex]a^{2} = b^{2} +c^{2} -2bcCosA[/tex] This is the cosine rule formula. Now all we need to do is substitute in the values. We are using the cosine rule because we aren't given any angle values. We use Further Trigonometry instead of SOHCAHTOA as this clearly isn't a right-angled triangle. SOHCAHTOA only applies to triangles with a 90 degree angle, also known as a right-angled triangle. Let's rearrange the cosine formula so that we have everything equal to A instead.
[tex]A = cos^{-1}(\frac{b^{2} + c^{2} - a^{2} }{2bc})[/tex]
We will work out BAC first.
a = 5
b = 4
c = 7
[tex]A = cos^{-1}(\frac{4^{2} + 7^{2} - 5^{2} }{2(4)(7)})[/tex]
A = 44.4 rounded to 3 significant figures
Next, we will work out BCA.
a = 4
b = 5
c = 7
[tex]A = cos^{-1}(\frac{5^{2} + 7^{2} - 4^{2} }{2(5)(7)})[/tex]
A = 34.0 rounded to 3 significant figures
The answer is F, Obtuse triangle and E, Scalene triangle
If we just worked out BAC, we would have noticed that by assuming BCA was also 44.4, the obtuse angle would be 91.2 degrees, which is barely above 90 degrees, therefore we would have correctly guessed the triangle as obtuse from there-on. I just worked out BCA as evidence to support that Triangle ABC cannot be isosceles, therefore we can eliminate that option and classify this triangle as Obtuse.
I hope my explanation helps!!

___ m3
Answers
Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = [tex]\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24[/tex]
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.

a car completes a 200km journey at an average speed of xkm/h. the car completes the return journey of 200 km at an average speed of (x+10)km/h. show that the difference of the time taken for each of the two journeys is 2000/x(x+10) hours
Answers
Answer:
The difference of the time taken for each of the two journeys is given as follows;
The difference of time = 2000/(x·(x + 10))
Step-by-step explanation:
The speed with which the car completes the 200 km journey = x km/h
The speed with which the car completes the return journey = (x + 10) km/h
Let t₁ represent the time it takes the car to complete the 200 km and let t₂ represent the time it takes the car to complete the return journey, we have;
t₁ = 200/(x)
t₂ = 200/(x + 10)
The difference of the time taken for each of the two journeys = t₁ - t₂
We have;
t₁ - t₂ = 200/(x) - 200/(x + 10)
200/(x) - 200/(x + 10) = (200·(x + 10) - 200·x)/((x)·(x + 10)) = 2000/((x)·(x + 10))
∴ t₁ - t₂ = 2000/((x)·(x + 10)) = 2000/(x·(x + 10))
The difference of the time taken for each of the two journeys = t₁ - t₂ = 2000/(x·(x + 10))

Simplify.
