If your school is 30 feet tall and 1 feet is 1.26 cm, you would multiply 30 and 1.26 to get the height of the scale model which is 37.8 cm. Then, if each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks you need to build the school, which is 6.
The model will be 6 toothpicks tall.

The ratio in it's lowest form is 7:4
So a complementary angle is going to equal 90 degrees.
The equation is : x - 10 + 4x - 10 = 90
Then, add together the matching terms : 5x - 20 = 90
Add 20 to both sides : 5x = 110
Then divide both sides by 5 : x = 22
Insert the value 22 into the first equation : (22 - 10) + (4*22 - 10) = 90
Solve : 12 + 78 = 90
Angle UVW = 12 and angle XYZ = 78
Answer:
0
Step-by-step explanation:
To evaluate log10 1 without using a calculator
From the laws of logarithm,
Logₐ b = x
Then a^x = b
Therefore if log10 1 = x
10^x = 1
From the laws of indices (any figure raised to the power of 0 = 1)
a^0 = 1
Therefore, x = 0
log10 1 = 0
