Answer:
(41%, 53%)
Step-by-step explanation:
Given that:
Politician Alec's vote = 47%
Candidate Simeon = 42%
Margin of Error = 6%
Interval which describes Alec's chances of winning
Chances of Alec winning (p) = 47%
Margin of Error = 6%
Interval :
p ± margin of error
47% ± 6%
47% - 6% ; 47% + 6%
(41%, 53%)
ermest works in the shipping department loading shipping crates with boxes. Each empty crate weighs 150 lb. How many boxes, each weighing 35 lb, can Ernest put in the crate if the total weight is to be no more then 850 lb?
Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)
850-150=700
700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.
700/35 = 20
Ernest can put in 20 boxes in the crate.

what is 90% of 20????
Answer:
18
Step-by-step explanation:
Multiply 20 by 0.90 (that is 90%)
18 is the answer
Hope this helps :)
Answer:
18
Step-by-step explanation:
Hello there. This problem can be easily solved by setting up a ratio.
This would be as follows
[tex]\frac{90percent}{100}[/tex] x [tex]\frac{x}{20 }[/tex]
after solving for x we find that 90% of 20 should be 18.
Hope this helps!
When an item is marked up by a certain percent and then marked down by the same percent, is the sale price equal to the price before the markup and markdown? Explain.
Answer:
Step-by-step explanation:
For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises. A computer software retailer used a markup rate of 40%.

Describe the process for calculating the volume of a pyramid. Use complete sentences.
Answer:
In order to find the volume of a pyramid you will first multiply length by width and height. Then the answer you get from that will be divided by three. Whatever you get from that will be the volume.
Alex is thinking of a number. Twenty less
than one fourth of the number is -45. Find Alex’s number.
i need the equation.
Answer:
¼x - 20 = -45
¼x = -25
x = -100
Step-by-step explanation:
To solve this we can write it out into an equation. Let's use the variable x for the number Alex is thinking of. Then we can take out each information to see what it means mathematically. We need to see what operation is being done.
"twenty less than one fourth of the number" The second part is using mutiplication, as indicated by "of." So we would write a quarter (one fourth) times the number (x). The first part is using subtraction, indicated by "less than." This would be expressed by "- 20"
Putting it together:
¼x - 20
"is -45" this is joining the expression to an equation. So this would simply mean " = -45 " Then our equation is:
¼x - 20 = -45
Now we can solve it.
¼x - 20 = -45
¼x = -25
x = -100
у= - 3х - 3
у = х + 5
Answer:
(x,y)=(-2,3)
Step-by-step explanation:
Since both expressions -3x-3 and x+5 are equal to y, set them equal to eachother forming an equation in x
-3x-3=x+5
solve the equation for x
x= -2
substitute the given value of x into the equation y=x+5
y= -2 +5
solve the equation for y
y=3
the possible solution of the system is the ordered pair (x,y)
(x,y) = (-2,3
check if the given ordered pair is the solution of the system of equations
{3= -3x(-2) -3
{3= -2 +5
simplify the equalitites
{3=3
{3=3
since all the equalitites are true, the ordered pair is the solution of the system
(x,y)=(-2,3)
Hope this helps!! I would really appreciate a brainliest

Can somebody please explain to me how to do this !!!?
Answer:
Slope is 4
Step-by-step explanation:
Take a y value (like 18) and subtract it with another y value (14). This will be 4. Now take a x value corrleating with your y value (like 4 since it correlates with 18) and subtract is with another x value correlating with your other y value (it'll be 3 because it's correlating with 14). The x will become 1. Now divide the y and x, so it will be 4 b/c it's 4 divided by 1.

John is at a local bait shop; he wants to buy bait for his fishing trip. At the store, they are selling live bait for $12 a pound and natural bait for $7 a pound. John would like to get at least 3 pounds of live bait, but he only has a budget of $63. Let x be the amount of live bait and y be the amount of natural bait. Model the scenario with a system of inequalities. And make a graph that fits both inequalities. I will give brainliest.
Answer:
26 for live bait
Step-by-step explanation:
12 times 3

The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each. The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45. How many packages of each size were shipped?
Given :
The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each.
The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45.
To Find :
How many packages of each size were shipped.
Solution :
We know, 1 pound = 16 ounces.
So, 20 pound = 20×16 = 320 ounces.
Let, number of large and small box are l and s.
So,
25l + 6s = 327 ...1)
0.45s + 1.20l = 18.45 ...2)
Solving both the equations, we get :
x = 9 and y = 17
Therefore, package smaller and big size are 17 and 9 respectively .
Hence, this is the required solution.

It is an isosceles triangle which has two angles of the same measurement, Pretty easy to figure out.
Answer:
x= 64 ansdy=52
Step-by-step explanation:
Since the 64 line is congruent to the "x" line, it must be 64. A triangle's angles equal 180 so 180-64-64= 2 giving you "y"
The cost of raincoat is rs 400 and VAT is rs 40 find the rate of VAT

which triangle congruence criteria can always be used to prove two triangles congruent in a coordinate plane?
Answer:
The Side-Side-Side congruency criteria
Step-by-step explanation:
The Side-Side-Side (SSS) congruency criteria can always be used to prove two triangles are congruent in a coordinate plane
When two triangles are presented in the coordinate plane, the coordinates of the vertices of both triangle will be given by the coordinates of their points on the coordinate plane
The length of the sides of each triangle will be given by the distances, d₁, d₂, d₃, between the coordinates of their vertices as follows;
[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The two triangles are congruent when the length of the three sides d₁, d₂, and d₃ of one triangle ABC, are congruent to the three sides d'₁, d'₂, and d'₃ of the other triangle A'B'C'.

solve 49x + 9 equals 49x + 83. does an equation have one solution, no solution, or infinitely many solutions? write two equations in one variable that have the same number of solutions as his equation
it has no solution. 0=74 means it cannot be solved. if it was 0=0 then it would be infinite solutions

Answer:
Heyyyy :)
1- 7 units up 4 down; dil 2
2- clockwise rotation
3- reflection; dil 2
4- Counter-clockwise rotation
Step-by-step explanation:
I'm sorry if you don't understand but when I was writing my notes I shortened it and I don't remember the real wording.
But if you read the problems the two that are very similar are the same but one of the problems says clockwise and the other is counter-clockwise. And the one that is shorter than the other three problems is the reflection; dil 2, and the other is kinda obvious. I hope you understand!!!!!
Byeeeee :)
