Answer:
m∠CBD=68°
Step-by-step explanation:
BA is perpendicular to BD, meaning they form a right angle (90°)
This means m∠CBD + m∠ABC=90, or they are supplementary.
We have expressions given for these angles, so
4x+52+8x-10=90
12x+42=90
12x=48
x=4
Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.
4(4)+52=68
m∠CBD is 68°.
In this question, importance has to be given to all the information's provided. Based on these information's the answer to the question can be reached.
Total length of ribbon = 1.5 yards
1 yard = 3 foot
1.5 yards = 3 * 1.5 feet
= 4.5 feet
So the total length of the ribbon is 4.5 feet.
Now
Cost of 1 foot of ribbon = 10 cents
Then
Cost of 4.5 feet of ribbon = 10 * 4.5 cents
= 45 cents.
= 45/100 dollars
= 0.45 dollars
So the cost of the total ribbon in dollars is $0.45.
2(6d-13c) is an equivalent way to write this expression
One statement that is true when re-writing expression is that the terms cannot be combined because the variables are different.
Are there statements you can chose from, like multiple choice answers?
Answer:
I guess the question is when her hair will be almost 16cm long.
So she needs to grow hair almost 12 cm of hair. Because 16-4=12
To grow 12cm hair she needs 8 months (12/1.5=8)
So Svetlana needs to cut her hair before 8th month.
