Answer:
1.12 × 10^-3
Step-by-step explanation:
The computation of the width of the photograph is as follows:
As we know that
Area of the rectangle = length × width
33 ÷ 20 square inches = 1475 inches × width
So, the width is
= Length ÷ area
= 1475 inches ÷ (33 ÷ 20 square inches)
= 1.12 × 10^-3
To find how much they bought each book for, you must divide by 10. 74 divided by 10 is 7.4. Then if they are selling them for 20% more, then multiply 7.4 and 1.2
Your answer is $8.80
Answer:
15 boys.
Step-by-step explanation:
A class constituting of boys and girls:
Has a total of 35 students.
The number of girls outnumber that of boys by 5.
Let the number of boys be x such that the number of girls is x + 5.
∴
x + x + 5 = 35
2x + 5 = 35
2x = 35 - 5 = 30
x = 30/2 = 15
So there are 15 boys and 35 - 15 = 20 girls.
*<em>I believe you can now solve the second question.</em>
Answer: m∠R=30° m∠N=30°
If ΔRST is congruent to ΔNPQ, then we can infer that m∠R is congruent to m∠N
m∠R=-7x+9
m∠N=-10x
If both angles are congruent, we can solve for x...
-7x+9=-10x
add 7x to both sides
9=-3x
divide both sides by -3
-3=x
Now that we know the value of x, we can solve for the measure of the angles.
m∠R=-7x+9
m∠R=-7(-3)+9
m∠R=21+9
m∠R=30°
m∠N=-10x
m∠N=-10(-3)
m∠N=30°
