The elevator in a new building traveos a maximum distance of 32 meters. Find the eatimated distance traveled with yards
The estimated distance which is the yard measurement equivalent of the maximum distance 32 meters travelled is; 35.008 yards.
What is the yard measure equivalent of the 32 meters distance travelled by the elevator?It follows from the task content that the maximum distance given,; 32 meters be expressed in terms of its yard measure equivalent.
On this note, since 1 meter is equivalent to; 1.094 yards. It follows from proportion that 32 meters is equivalent to;
= 32 × 1.094 yards
= 32.008 yards.
Ultimately, the estimated distance which is the yard measurement equivalent of the maximum distance 32 meters travelled is; 32.008 yards.

Triangle BCD has the following side lengths: BC = 60, CD = 50
Triangle RST has the following side lengths: RS = 11x-4, ST = 70
What is the value of x? (put just the number in the first box)
What is the length of side RS? (put just the number in the second box)
The value of x is 11 and the length of side RS is 117
How to determine the value of x?The given parameters are
BC = 60 and CD = 50
RS = 11x - 4 and ST = 70
Express as a ratio
BC : CD = RS : ST
So, we have
60 : 50 = 11x - 4 : 70
Express as fraction
So, we have
60/50 = (11x - 4)/70
Cross multiply
So, we have
50 * (11x - 4) = 70 * 60
Divide both sides by 50
So, we have
11x - 4 = 84
This gives
11x = 88
Divide both sides by 11
So, we have
x = 11
Substitute x = 11 in RS = 11x - 4
RS = 11 x 11 - 4
Evaluate the product and the sum
RS = 117
Hence, the value of x is 11 and the length of side RS is 117

Answer:
He can buy 4 books with 2 dollars remaining
Step-by-step explanation:
30/7 = 4 R2
Answer: 4 books.
Explanation: First you divide $30 by 7, and you get 4 and 2/7 (2/7 as the remainder) left over. So you can't have 4 and 2/7 books, it has to be a whole number.
Therefore, he can buy 4 books. I hope this helped!

The ratio 4/7 : 8/21 has a unit rate of 3/2. True or false?
The statement 'The ratio 4/7 : 8/21 has a unit rate of 3/2.' is True.
In this question, we have been given a statement 'The ratio 4/7 : 8/21 has a unit rate of 3/2.'
We need to check whether the statement is True or False.
We have been given the ratio of two fractions.
4/7 : 8/21
We know that for any non zero real numbers a, b, c, d,
a/b : c/d = a/b × d/c
So, we can write given ratio as,
4/7 : 8/21
= 4/7 × 21/8
= 3/2
In the given statement, it is mentioned that, the ratio 4/7 : 8/21 has a unit rate of 3/2.
This means, the given statement is correct.
Therefore, the statement 'The ratio 4/7 : 8/21 has a unit rate of 3/2.' is True.

Suppose log5=b , then what is the exact value of log5^4?
Answer:

The power of 10 is b.
So log(5⁴) means that

A baker has 134 cup of sprinkles to spread on cupcakes. Each cupcake needs 18 cup of sprinkles. How many cupcakes can the baker sprinkle?
Answer:
[tex]Cupcakes = 7[/tex]
Step-by-step explanation:
Given
[tex]Total\ Sprinkles = 134[/tex]
[tex]Sprinkle\ per\ cupcake = 18[/tex]
Required
Determine the number of cupcakes
To do this, we simply divide the total cups of sprinkle by the sprinkles per cupcake
[tex]Cupcakes = \frac{Total\ Sprinkles}{Sprinkle\ Per\ Cupcake}[/tex]
This gives:
[tex]Cupcakes = \frac{134}{18}[/tex]
[tex]Cupcakes = 7.44[/tex]
[tex]Cupcakes = 7[/tex] approximated
Hence, 7 cupcakes are needed
