there are red and white roses in a vase 30% are red .there are 21 white roses.how many are there in total
Answer:
Step-by-step explanation:
21 roses are white so that is 70%
so that would be 70/100 and can reduce to 7/10
and the percent of red would be 3/10
so we can do 21 divided by 7 which equals 3
then we can do 3 x 3 because 3/10 which equals 9
then you do 21 + 9= 30
so the answer is 30.
One match releases approximately 1,100 joules of heat energy when it is lit. If 1 joule equals 0.239 calories , how many of these matches must be lit to produce 2, 100cg calories of heat energy ?
If 1 match releases 1100 joules of heat energy and we know that 1 joule = 0.239 calories. This means that 1 match releases 1100 * 0.239 calories
1 match releases 262.9 calories.
Again, if 1 match produces 262.9 calories, then
1 match = 262.9 calories
x match = 2100 calories
if we cross multiply, we have
1 match * 2100 calories = x match * 262.9 calories
x match = 2100/262.9
x match = 7.987 matches
Therefore, approximately 8 matches are needed

Answer:
41910.
Step-by-step explanation:
We can calculate this by first finding the sum for k = 1 to 50 then subtracting the sum for k = 1 to 14.
We use the formula (1/6)n(n+1)(2n+1)
So for 1 to 50 its 1/6 * 50* 51 * 101 = 42925
and for 1 to 14 it comes to 1/6*14*15*29 = 1015
So the answer is 41910.

Answer:
f(6) = 53
Step-by-step explanation:
f(x) = 10x - 7
We want to find f(6)
To do so simply substitute 6 for x in the equation
Equation: 10x - 7
x = 6
f(6) = 10(6) - 7
multiply 10 and 6
f(6) = 60 - 7
subtract
f(6) = 53
Answer:
[tex]f(x)=53[/tex]
Step-by-step explanation:
For [tex]f(x)=10x-7\\[/tex] substitute x for 6

Evaluate a+b+cd if a=7/8 , b=−7/16 , c=0.8 , and d=1/4 . Write your answer as a fraction in simplest form.
After solving the given expression, the value obtained from it in form of simplest fraction is equal to 5.1/8.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given data in the question,
a = 7/8
b = -7/16
c = 0.8 and
d = 1/4
And the equation is a+b+cd
7/8 + (-7/16) + (0.8)(1/4)
7/16 + 0.2
= 10.2/16
In simplest form, it is written as 5.1/8.

2.7z + 1.2z - 6.5 = 0.7
Answer:
= 1 . 8 4 6 1 5 3 8 4 6
Step-by-step explanation:
I took the test yesterday and I got a 100 on the math part
Answer/Step-by-step explanation:
Combine multiplied terms into a single fraction
2.7z+1.2z−6.5=0.7
2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7
Combine multiplied terms into a single fraction
2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7
2 7 /1 0 + 6 5 − 6 . 5= 0 . 7
Find common denominator
2 7 /1 0 + 6 5 − 6 . 5= 0 . 7
[tex]\frac{27z}{10} +\frac{2.6z}{10} +\frac{10(-6.5)}{10} =0.7[/tex]
Combine fractions with common denominator
[tex]\frac{27z+2*6z+10(-6.5)}{10} =0.7[/tex]
Multiply the numbers
[tex]\frac{27z+12z-65}{10} =0.7[/tex]
Combine like terms
[tex]\frac{39z-65}{10} =0.7[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]10*\frac{39z-65}{10} =10*0.7[/tex]
Cancel multiplied terms that are in the denominator
39z-65=10*0.7
Multiply the numbers
39z-65=7
Add 65 to both sides of the equation
39z-65+65=7+65
Simplify
39z=72
Divide both sides of the equation by the same term
[tex]\frac{39z}{39} =\frac{72}{39}[/tex]
Simplify
Z= 1.846153846
