the cost of 7 toys is AED 294. the cost of 5 toys. (Unitary method)
Answers
Answer:
AED 210
Step-by-step explanation:
If the cost of 7 toys is AED 294, this is written as;
7 toys = AED 294
To get the cost of 5 toys, this is written as;
5 toys = x
Divide both expressions
7/5 = 294/x
Cross multiply
7x = 5 * 294
7x = 1470
x = 1470/7
x = 210
Hence the cost of 5 toys is AED 210

The angle of elevation from a kicker's foot on the football field to the top of the goal post is 17 degrees. If he is standing 131 feet from the base of the goal post, how tall is the goal post?
Answers
Answer:
The goal post is 40.05 feet tall.
Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.
You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in
Sin
Cos
Tan
So you need to use tan.
Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:
[tex]Opp = Tan * adj
So simply plug these values in:
[tex]Opp =131 * tan(17) = 40.05
So the goal post is 40.05 feet tall
a flomming tile has the shape of a parallelogram whose base is 24cm and height is 10 cm how many tiles are required to cove the floor of area 1080m2
Answers
Answer:
4 1/2 tiles are needed to cover this area
Step-by-step explanation:
Mathematically, the area of a parallelogram is the product of the base and the height
We have this as;
24 * 10 = 240 cm^2
So the area of a tile is this
The number of tiles that will cover the given area will be;
1080/240 = 4.5 tiles

Write a second equation whose graph goes through (0,1) so the system has no solutions.
Answers
Answer:
y = 5x + 1
Step-by-step explanation:
Hello There!
Equations that have no solutions are parallel
So the line we are going to create an equation for has the same slope as the line drawn
To find the slope we do change in y divided by change in x
as y goes 5 x goes up 1
so the slope is 5/1 or 5
The requirements for the equation is it has to go through the points (0,1)
The ordered pair listed is the y intercept so the equation would be
y = 5x + 1

How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answers
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution
