abdul rahman went to fidh market to buy two typesof fish.cost of one type of fish is 95 dollars per kg and the second type of fish costs 130 dollors per kg. can he buy two kilograms of each with 800 dollors.
Answer:
Yes
Step-by-step explanation:
95 multiplied by 2 is 190
130 multiplied by 2 is 260
190+260 is 450
Answer:
95 x 2=190
130 x 2= 260
260+190= 450
he can and will still have some change
800-450=350

Third-degree, with zeros of -3,-2, and 1, and passes through the point (3,9)
Three zeroes of a third-degree polynomial are given, with the graph passing through the point (3,6). To find the equation of this, first, let us set up how a 3rd-degree polynomial factored out should look like:
y = a(x+b)(x+c)(x+d).
Since the zeroes of the function are -3, -2, 1, the equation will look like y = a(x+3)(x+2)(x-1). To solve for a, plug-in x = 3 and y = 6 from the point (3,6). After replacing the variable a in the equation with the answer, you will have the solution for the problem.
Third-degree, with zeros of -3,-2, and 1, and passes through the point (3,9) then the polynomial p(x) is (3/20)(x-1)(x+2)(x+3)
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
-3 is a root... (x+3) is a factor
-2 is a root... (x+2) is a factor
1 is a root... (x-1) is a factor
p(x) = a(x-1)(x+2)(x+3)
(3, 9) is on graph so p(3)=9
9=a(3-1)(3+2)(3+3)
9=a(2)(5)(6)
9=60a
Divide both sides by 60
a=9/60
a=3/20
p(x) = (3/20)(x-1)(x+2)(x+3)
Hence, third-degree, with zeros of -3,-2, and 1, and passes through the point (3,9) then the polynomial p(x) is (3/20)(x-1)(x+2)(x+3)

Biologists want to estimate the number of deer living in a certain region. They will use a method known as a hair snare. A hair snare is a length of barbed wire set up near a salt lick, where deer can lick minerals and nutrients from salt deposits. The wire snares hair from the neck of the deer. The hair is collected and sent for analysis. The biologists will randomly place 90 salt licks throughout the region. The region consists of 3 areas: the town, the forest, and the lake, as shown in the following diagram
(a) Two methods have been proposed for choosing where to place the salt licks: a simple random sample or a stratified random sample, with the area as strata. Give one reason why the stratified might be the better method for choosing where to place the salt licks.
The stratified random sample is better because this will lead to more accurate results.
Sampling is a method that implies randomly selecting participants, places, etc. as part of an experiment. There are two main methods for sampling:
Simple random sampling: This will mean choosing randomly the places to place the salt licks.Stratified random sampling: This means dividing the total area into subareas and then choosing random spots to place the salt licks.The second method is the best to use because this will guarantee in each subarea there is the same number of salt licks. Preventing many salts licks to be together or a subarea to not having any salt licks.
Based on this, we can conclude this method will lead to more accurate results.

Answer:
Stratified random sampling is the better method to use.
Step-by-step explanation:
Stratified random sampling would be a better method for choosing where to place the salt licks because it will guarantee that each subarea has the same amount of salt licks, and prevent many salt licks from being in the same area or some subareas from having no salt licks at all.

Answer:
A
Step-by-step explanation:
We can calculate the equation of the lines based on two points. First line m:
y = ax +b
where a is the slope and b is the y-intercept. To find the slope we use the x and y of the points as:
a = [tex]a = \frac{y_1-y_2}{x_1-x_2} = \frac{4- -32}{2- -4} = \frac{36}{6} = 6.[/tex]
So:
y = 6x + b
we can find the y intercept by substituting the x and y for one of the points:
solving for b:
b=-32-(6)(-4)= -8.
So the equation is:
y = 6x - 8.
We can change it to:
y + 8 = 6x
8 = 6x - y.
So it’s (A).
Hope that helps!

Answer:
Step-by-step explanation:
four times the sum of a number and 9 is 16
4 *(x + 9) = 16
4x + 36 = 16
4x = 16 - 36
4x = -20
x = -5

make x the subject of the following formula x^2+3=h
2x=2y=p
s=x^2-3
Answer:
x^2+3=h
to make x the subject of the formula,move 3 to the other side making it negative
x^2 = h + 3
to take out the square,take the square root of both sides.
√x^2 = √ h + 3
x = √ h + 3.

The Coney Island Boardwalk is 2.7 miles long.
A person walks at the average speed of 3 mph.
How long will it take the person to walk the boardwalk to the end and back?
Answer = 1.8
Step 1) 3 ÷ 2.7 = 0.900
Step 2) 0.900 x 2 = 1.8
Time taken by the person to walk the boardwalk to the end and back is 0.9 hours.
Given that, The Coney Island Boardwalk is 2.7 miles long.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
A person walks at the average speed of 3 mph.
We know that, speed = Distance/Time
= 2.7/3
= 0.9 hours
Hence, time taken by the person to walk the boardwalk to the end and back is 0.9 hours.

Question: The triangles shown ARE similar. Explain how the triangles are similar and identify the similarity theorem: AA, SSS, or SAS
Triangle ABC~ Triangle AFG
Answer:
SAS
Step-by-step explanation:
The triangles are similar by SAS. Two side lengths are given, and we know that vertical angles are congruent.
It is not SSS because we do not know the side lengths of FG and BC.
It is not AA because we do not know two angle measurements.

C: y=1/2x + 2
D: y=2x-4
GIVING BRAINLY TO CORRECT ANSWER
Step-by-step explanation:
(x1,y1) = (-4,0)
(x2,y2) = (0,2)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 0)/(2 - 0) = (x + 4)/(0 + 4)
y/2 = (x + 4)/4
4y = 2(x + 4)
2y = x + 4
y = x/2 + 2
