Answer:
9kg
Step-by-step explanation:
Because it is said that Polly's mass is 3kg but, Barney's mass is 3 times more kg than Polly.
So we multiply 3 (Polly's mass) multiplied by 3(cuz it is said three times more). So 3*3 = 9kg
What is the area of the obtuse triangle below?
The area of the triangle is 126 square units. Then the correct option is D.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The height of the triangle will be 12 units and the base of the triangle will be 21 units. Then the area of the triangle is calculated as,
A = 1/2 x 21 x 12
A = 21 x 6
A = 126 square units
Thus, the correct option is D.

Answer: a) and b)
Step-by-step explanation: Lets find the percentages for each option.
a). with 1-11 without 12-20
Here there are 20 shopers. From 1 to 11, there are 11 shoppers. From 12 to 20, there are 9 shoppers. 11 of 20 have credit cards, and 11/20 = 0.55. So this option is correct
b). with 1-33 without 34-60
Here there are 60 shoppers. 1 to 33 there are 33 shoppers with store credit cards. 33/60 = 0.55. So this is also a simulation which represents this situation.
c). with 1-24 without 25-40
Here there are 40 shoppers. 1 to 24, so there are 24 shoppers with the store credit card. 24/40 = 0.6. So this is not a correct option.
d). with 1-21 without 22-40
Here there are 40 shoppers, of which 21 have the credit card. 21/40 = 0.525, so this is not one of the options
e). with 1-18 without 19-40
Here there are 40 shoppers, of which 18 have the credit card. 18/40 = 0.45, so this is not one of the options.
f). with 1-36 without 37-80
Here there are 80 shoppers, of which 36 have the credit card. 36/80 = 0.45,
so this is not one of the options.

What is the total area, in square inches, of the shaded sections of the trapezoid below?
Help test
Total area of shaded region in trapezoid is 54.4in²
What is trapezoid?A trapezoid is a four-sided, quadrilateral shape with two parallel sides, which are called the bases, and two non-parallel sides, which are called the legs.
here, we have,
The formula for the area of a trapezoid is:
Area = (1/2) × (sum of the bases) × (height)
The Shaded region in trapezoid form right angled triangle.
Area of 1st shaded region=area of right triangle
=1/2×b×h
=1/2×6.8×7.4
=25.16in²
Area of 2nd shaded region=area of right triangle
=1/2×b×h
=1/2×6.8×8.6
=29.24in²
Hence, total area of shaded region in trapezoid is 54.4in²

-8y- 6x = 32
Answer:
y = -3/4x - 4
Step-by-step explanation:
-8y -6x = 32
-8y = 32 + 6x -- isolate the y variable.
(-1) -8y = 32 + 6x (-1) -- the y has to be a positive number so multiply every single number by -1
8y/8 = -32/8 - 6x/8 -- divide both sides by 8
y = - 4 - 6/8x
y = -3/4x -4 - simplify the fraction and that is your answer

Deer ticks can be carriers of either Lyme disease or human granulocytic ehrlichiosis (HGE). Based on a recent study, suppose that 16% of all ticks in a certain location carry Lyme disease, 10% carry HGE, and 10% of the ticks that carry at least one of these diseases in fact carry both of them. If a randomly selected tick is found to have carried HGE, what is the probability that the selected tick is also a carrier of Lyme disease
Answer:
0.2364
Step-by-step explanation:
We will take
Lyme = L
HGE = H
P(L) = 16% = 0.16
P(H) = 10% = 0.10
P(L ∩ H) = 0.10 x p(L U H)
Using the addition theorem
P(L U H) = p(L) + P(H) - P(L ∩ H)
P(L U H) = 0.16 + 0.10 - 0.10 * p(L u H)
P(L U H) = 0.26 - 0.10p(L u H)
We collect like terms
P(L U H) + 0.10P(L U H) = 0.26
This can be rewritten as:
P(L U H)[1 +0.1] = 0.26
Then we have,
1.1p(L U H) = 0.26
We divide through by 1.1
P(L U H) = 0.26/1.1
= 0.2364
Therefore
P(L ∩ H) = 0.10 x 0.2364
The probability of tick also carrying lyme disease
P(L|H) = p(L ∩ H)/P(H)
= 0.1x0.2364/0.1
= 0.2364

Similar triangles are those triangles whose corresponding sides are in the same ratio. The length of the sides ST and RT are 5 units and 3 units, respectively.
What are similar triangles?Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by ‘~’ symbol.
Given that the two triangles are similar because the two have the same ratio. Therefore, the ratio of the corresponding sides in the triangle can be written as,
Ratio = AB/RS = BC/ST = AC/RT
Ratio = 18/6 = 15/ST = 9/RT
Now, using the ratio the length of the sides can be written as,
18/6 = 15/ST
ST = (15 × 6)/18
ST = 5 units
18/6 = 9/RT
RT = (9 × 6)/18
RT = 3 units
Hence, the length of the sides ST and RT are 5 units and 3 units, respectively.

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
Answer:
A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.
Step-by-step explanation:
To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.

Determine whether the graph shown to the right represents a function.
Choose the correct answer below.
O A. No, because no vertical line can be drawn that intersects the graph more than once.
B. Yes, because a vertical line can be drawn that intersects the graph more than once.
C. No, because a vertical line can be drawn that intersects the graph more than once.
D. Yes because no vertical line can be drawn that intersects the graph more than once.
Using the function definition, it is found that the correct option is:
C. No, because a vertical line can be drawn that intersects the graph more than once.
--------------------------
In a function, each value of the input x can have only one respective output y.In a graph, for a value of x, there can only be one value of y.To verify this, we trace a vertical line, and if it intercepts the function more than once, the graph is not a function.In the picture at the end, it can be seen that multiple vertical lines intersect the function twice, thus, not a function, and the correct option is C.A similar problem is given at https://brainly.com/question/12463448
