Answer with explanation:
Total Length of Ribbon = 9 feet
Length of Ribbon used to make bookmark foot
Total number of ribbons Jim can make from 9 feet of ribbon
=27 Ribbons
there is 12 inches in a foot. 1/3 of a foot would be 4 inches
take 9 x 12 (Inches in a foot) = 108 and divide by four
the answer is 27. so he can get 27 ribbons out of 9 ft. of ribbon
The ratio of Lauren's Age to Kristen's Age =
Ratio of two numbers is a quantitative relationship between two numbers showing that how one number is increasing or decreasing with respect to other number.
If a and b are two numbers then the their ratio r is represented by the equation (1)
Lauren' s Age =
Kristien's Age =
For Finding out the ratio of two numbers we simply divide them.
Let x be the ratio of Lauren's age to Kristen's age, = x = /.....(2)
On simplifying equation (2) we get
x =
So the ratio of Lauren's Age to Kristen's Age =

Subtract 66 from both sides
2x^2+12x -66 = 66-66
2x^2+12x-66= 0
Use quadratic formula with a=2, b=12 , c= -66
x= −b±√b2−4ac2a
x=−(12)±√(12)2−4(2)(−66)2(2)x=−12±√6724x=−3+√42 or x=−3−√42Answer:x=−3+√42 or x=−3−√42
Answer:
A
Step-by-step explanation:
The exponent in the number Jerome writes will be anywhere between 6 to 7.
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
Jerome is writing a number in scientific notation.
Let's suppose the number is x
The number x is greater than one million and less than ten million.
In scientific notation:
We can say that from the above inequality that the exponent of the number will be between 6 to 7.
Thus, the exponent in the number Jerome writes will be anywhere between 6 to 7.

One million: 10^6
Ten million: 10^7
So the exponent will be anywhere between 6 and 7, inclusive
B) 100
C) 1000
d) 10,000
The number should be multiply is 10.
In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The twofactors and the product are parts of a multiplication problem.
Given:
n=0.9
Now, there is one number behind decimal point.
So, we have to multiply it by 10 to convert it into fraction from decimal.
Thus,
10n = 0.9*10
10n = 9
n = 9/10
Hence, the number must be multiplied is 10
