woah this is some crazy is
Answer:
z = 70
Step-by-step explanation:
Explanation: To solve this proportion for z, we can use cross products.
When we get the equation 5z = 350, we can get z by itself on the left side of the equation by dividing both sides of the equation by 5. On the left, the 5's cancel each other out and we have z. On the right, 350 divided by 5 simplifies to 70 so we have z = 70.
Answer:
10=40
50=30
Step-by-step explanation:
Suppose the number of 10 paise coins =x
∴ the number of 50 paise coins =70−x
Now, value of 10 paise coins = Rs.
10
x and value of 50 paise coins = Rs.
2
70−x
Total value of coins =
10
x
+ 2
70−x
∴ 10
x + 2
70−x =19
Multiplying both sides by 10, (LCM of 10,2=10), we get
x+5(70−x)=19×10
x+350−5x=190
−4x=−160
−4
−4x = −4
−160
∴x=40
∴ number of 10 paise coins =40
Number of 50 paise coins =70−40=30.
Answer:
The length of the rectangle = 63 ft
Step-by-step explanation:
Let us assume the width of the rectangle = m ft
So, the length of the rectangle = 3 x Width = 3 x m = 3 m ft
Perimeter = 168 ft
PERIMETER OF A RECTANGLE = 2 (LENGTH + WIDTH)
⇒ 168 ft = 2 ( 3 m + m)
or, 168 = 2 ( 4 m)
or, 8 m = 168
⇒ m = 168/8 = 21
or, m = 21 ft
Hence, the width of the rectangle = m = 21 ft
And the length of the rectangle = 3 x m = 3 x 21 = 63 ft
Answer:
295 square feet
Step-by-step explanation:
Break the figure up into 3 rectangles, and then find the area of each rectangle and add all areas together.
15*3=45
19*10=190
15*4=60
45+190+60=295
