Answer:
-47, i think
Step-by-step explanation:
whenever i think of doing stuff with a bunch of signs just remember that a negative and a positive cancel out to be just a negative so the equation is really just -7-40.
Monte's Autorana is having an end-of-year clearance in which the TV ads proclaim that
all cars are sold at 5% markup over the dealer's cost. Monte has a new Exfinity for sale
for $18,970. On the Internet, you find out that this particular model has a dealer cost of
$17,500. Is Monte being honest in his advertising?
Answer:
No
Step-by-step explanation:
We first write out $17,500 as a multiplication to 5%
New price = 17500 x 1.05 = 18375 = $18,375
18375-17500 = 875
We then work out the tax on just the mark up of $875 increase
20% mark up = 875 x 0.20 = 175
18.375+175 = 18550
= $18,550 charge to be considered for 5%
However Monte would argue that tax on tax also applies to 875 x 1.20 = 1050
=$1050 and he is just asking to meet half tax costs an extra 10% of his own tax back of 17.500 x 20% that he paid = 17500 x 0.20 = 3500
tax he paid inclusive or non inclusive would be the same.
= $3500
10% of this = 3500 x 0.10 = 350
18550+350 = 18,900
Therefore it is not dishonest if mentioned in the terms and conditions.
We also universally can round 5% up by applying other charges to include promotion costs and even apply more for administration costs.

What is the area of triangle ABC? Round to the nearest square unit.
Triangle A B C is shown. The length of A C is 16, the length of C B is 8, and the length of A B is 10.
Heron’s formula: Area
8 square units
15 square units
33 square units
618 square units
The area of the triangle ABC is 33 square units
We have given that,
Triangle A B C is shown. The length of A C is 16, the length of C B is 8, and the length of A B is 10.
We have to determine the area of the triangle
What is the area of the triangle?[tex]\text{ Area }=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
A = area
s = semi-perimeter
a = length of side a
b = length of side b
c = length of side c\text{ Area } = area
s = semi-perimeter
use the given value in the above formula we get the area of the triangle ABC is,
Therefore the correct answer is 33 square units.

Letter b is asking for points inside of the shaded portion, and letter c is asking for the points that make up the triangle.
How can the point (12, 16) be explained? The highest point of the mountain defined by the function is 12 feet. The highest point of the mountain defined by the function is 16 feet. The width of the base of the mountain defined by the function is 12 feet. The width of the base of the mountain defined by the function is 16 feet.
Answer:
B The highest point of the mountain is defined by the function is 16 feet.

Saw it somewhere
The points (12, 16) can be explained as,
The highest point of the mountain defined by the function is 16 feet.
The width of the base of the mountain defined by the function is 12 feet.
Co ordinatesWhat are co ordinates?a group of variables that accurately depict a position. The first number on a graph represents the distance along, while the second number represents the distance up or down. For instance, the point (2,15) is located 2 units down and 15 units up.
What is Abscissa?The "x" coordinate of a point, as represented on the horizontal line, is another name for the abscissa.
What is Ordinates?The co ordinate that is displayed on the vertical line, commonly known as the "y" coordinate is called ordinates.
Description for the co ordinates (12, 16)As, 12 is written first on the co ordinates, that's why 12 is showing the abscissa on the horizontal line which is the width of the base of the mountain.
While, 16 here shows the ordinates on the vertical line which is the highest point of the mountain.

400 people are asked if they drink tea
7/10 say yes and 20% of the people who say yes drink three cups a day
Answer:
56 people drink 3 cups daily
Step-by-step explanation:
What's the total number of people that drink 3 cups?
Total number of people = 400
7 / 10 were asked said yes
Number of people that said yes = (7 / 10) × 400 = 280
280 people drink tea.
20% of 280 people drink 3 cups daily, whats the number = ?
20% of 280 = ?
20 / 100 = x / 280
(20 × 280) = (100 × x)
5600 = 100x
X = 5600 / 100
X = 56 people
56 people drink 3 cups of tea daily.
Answer:

Which equation has a constant of proportionality equally to 2? PLS HELP I WILL MARK AS BRAINLIEST
Hello there!
A would be the correct answer since 10 divided by 5 equals 2 and so it would be 2x.
B is wrong since it has a constant of proportionality equal to 1.
C is wrong since it has a constant of proportionality equal to 1/2.
D is wrong since it has a constant of proportionality equal to 11.
Answer:
A
Step-by-step explanation:
The equation of proportional quantities is
y = kx ← k is the constant of proportionality
A
y = [tex]\frac{10}{5}[/tex] x = 2x ← with k = 2
B
y = [tex]\frac{2}{2}[/tex] x = x ← with k = 1
C
y = [tex]\frac{2}{4}[/tex] x = [tex]\frac{1}{2}[/tex] x ← with k = [tex]\frac{1}{2}[/tex]
D
y = [tex]\frac{22}{2}[/tex] x = 11x ← with k = 11

Hi!
Got a question!
The question is: Find the volume of the shape above(if youre using the app) or below ( if you are using the website ).
Thanks !!
Answer:
404.09x cm³ (to 5 s.f.),
where x is the unknown height of the shape.
Step-by-step explanation:
Volume of the shape
= base area × height
= (large semicircle- small semicircle) × thickness of shape
Area of circle= [tex]\pi {r}^{2} [/tex]
Area of semicircle= [tex] \frac{1}{2} (\pi)( {r}^{2} )[/tex]
Diameter of small circle= 14
Radius= diameter ÷2
radius= 14 ÷2
radius = 7 cm
Area of small semicircle
[tex] = \frac{1}{2} (\pi)( {7}^{2} ) \\ = \frac{49}{2} \pi[/tex]
Radius of large semicircle
= 35 ÷2
= 17.5 cm
Area of large semicircle
[tex] = \frac{1}{2} (\pi)( {17.5}^{2} ) \\ = \frac{1225}{8} \pi[/tex]
Base area of shape
[tex] = \frac{1225}{8}\pi - \frac{49}{2} \pi \\ = \frac{1029}{8} \pi[/tex]
Since the height if the shape is not given, I'm afraid I cant help you find the volume.
Let the height of the shape be x cm.
Volume of shape= [tex] \frac{1029x}{8} \pi \: cm^{3} [/tex]
