Answer:
Her drawing is 15 cm
Step-by-step explanation:
First we need to figure out how tall the object is. We can use proportions. Put drawing size over real life
1 cm 12 cm
------- = -----------
5 ft x ft
Using cross products
1*x = 12*5
x = 60 ft
In real life the statue is 60 ft
Now when Kia draws it 1 cm =4ft to xcm to 60 ft
1 cm x cm
------- = -----------
4 ft 60 ft
Using cross products
1*60 = 4x
60 =4x
Divide by 4
60/4 = 4x/4
15 =x
Her drawing is 15 cm
Answer: Game land sells 20 crayons for 5 cents less.
Step-by-step explanation:
Hi, to answer this question we have to calculate the price per crayon in each store, by dividing the amount paid in each case by the number of crayons that each store offers.
Toy world (T): 25/4 = 6.25 cents per crayon
Game land (G): 30/5 = 6 cents per crayon
Now, we have to multiply the cost per crayon by 20.
T=6.25 x 20 = 125 cents
G=6 x 20 =120 cents
So, comparing both costs, Game land sells 20 crayons for 5 cents less.
125-120 = 5 cents
The 3 inside angles of a triangle need to equal 180 degrees.
The angle below the 100 degrees would be 180-100 = 80 degrees.
Now you have 80 and 70, which equals 150 degrees.
Angle X = 180 -150 = 30 degrees
Answer:
x=1 y=4
1:4
Step-by-step explanation:
We have the following equation:
ax2 + bx + c = 0
Using the resolver we have:
x = (- b +/- root (b2 - 4ac)) / 2a
We have:
b2 - 4ac <0
Therefore the root is negative
