Answer:
1) 
2) 
3) 
Step-by-step explanation:
1) Length of a ruler = r
Height of Shiela = s
According to the question ,
5 times the length of a ruler increased by 2 .
⇒ 
Also , 5r + 2 is less than height of Shiela.
Hence , the linear inequality is ⇒
2) Let the cost of each t-shirt be 't' & cost of each short be 's'.
⇒ Cost of dozen of t-shirts = 12t and Cost of half a dozen shorts = 6s
According to the question ,
12t & 6s is not greater than Php 960.
Hence the linear inequality is ⇒
3) Let the number of Php 100-peso tickets be 'p' and let the number of Php 50-peso tickets be 'q'.
According to the question ,
Difference of p & q is not less than 30
Hence the linear inequality is ⇒
A Rhombus has four equal straight sides. We can assume that the rhombus in this problem is square-shaped with 90° angles.
m1 = 18x ; 90 = 18x ; 90/18 = x ; 5 = x
m2 = x + y ; 90 = 5 + y ; 90 - 5 = y ; 85 = y
m3 = 30z ; 90 = 30z ; 90/30 = z ; 3 = z
x = 5 ; y = 85 ; z = 3
x + y + z ⇒ 5 + 85 + 3 = 93
Basically, u just sub in any number for x and solve for y
y = -6x - 2.....lets say x = 0
y = 6(0) - 2
y = -2....so when x is 0, y is -2 .....(0,-2)
y = -6x - 2....lets say x = 1
y = -6(1) - 2
y = -6 - 2
y = -8.......another solution is (1,-8)
y = -6x - 2....lets say x = 2
y = -6(2) - 2
y = -12 - 2
y = -14....another solution is (2,-14)
y = -6x - 2....lets say x = 3
y = -6(3) - 2
y = -18 - 2
y = -20...another solution is (3,-20)
I think u get the idea now :)
Given:
A motorist traveled 250 miles on 11 gallons of gas.
To Find:
In the same vehicle, the distance that can be traveled in 16 gallons.
Answer:
Rounding to the nearest tenth, the distance traveled on 16 gallons of gas is 363.5 miles.
Step-by-step explanation:
We first find the number of miles that can be traveled on 1 mile of gas.
We do this by using the unitary method.
Given that in 11 gallons, 250 miles can be traveled in a certain vehicle.
So in 1 gallon, 250 ÷ 11 miles can be traveled. This is roughly equal to 22.72.
Next we will calculate how much distance he can go in 16 gallons. We multiply the distance traveled in 1 gallon by 16.
That is, in 16 gallons, the number of miles that can be traveled is 22.72 x 16 = 363.52.
Rounding to the nearest tenth, the distance traveled on 16 gallons of gas is 363.5 miles.
Answer:
254
Step-by-step explanation:
63.5 ÷ 0.25 =
= 63.5 ÷ 1/4
= 63.5 × 4
= 254
Answer: 254.
