Ling and her family ordered takeout that cost $50. Ling paid 4% sales tax and left a 10% tip
on $50. What was the total cost?
Answer:
57
Step-by-step explanation:
tax
= tax percentage×amount
= 0.04×50
= 2
The tax was $2.
tip
= tip percentage×amount
= 0.10×50
= 5
Based on the information given the total cost is $57.
Using this formula
Total cost=Takeout cost+ Sales tax +Tip
Where:
Takeout cost=$50
Sales tax=(4%×$50)=$2
Tip=(10%×$50)=$5
Let plug formula
Total cost=$50+$2+$5
Total cost=$57
Inconclusion the total cost is $57.

Ronnie's teacher wrote this expression on the board. (-4)(2) + (10/2) What is the value of this expression?
Answer:
The answer would be -3.
Step-by-step explanation:
If you follow PEMDAS, the first set of parenthesis, (-4)(2), would equal -8. The next set of parenthesis, (10/2), would equal 5. Adding -8 and 5 together gives you -3.
1 pts The function f(x) = 12,900(0.40)x models the population of ants in a house x days after their discovery. Which statement describes the population of ants?
Answer:
f(x) = 500 • 1.1x
Step-by-step explanation:
To solve the question, we need to understand that:
- The population of ants is going to increase with time as they mate and have a population positive growth rate.
- The initial number of ants is 500.
- The rate at which it increases will be multiplied with x months
We will work our way out by removing the wrong answers first
Since,
The population cannot be decreased so we can neglect the last two options involving 0.9 as it will result in a decrease in the population.
Now we are left with two options:
a) f(x) = 500 • 1.1x
b) f(x) = 1.1 • 500x
Since in the option (b) , 500 is multiplied with x , it is not possible as 500 is a constant initial amount and not a factor of growth of population. The growth factor is supposed to be multiple of x months.
So, the correct answer is f(x) = 500 • 1.1x
A tool box has the dimensions of 10 in by 7 in by 3 in. If Deena plans to double all three dimensions to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?
Answer:
She will not be correct
Step-by-step explanation:
Given data
Length=10in
Width=7in
Height=3in
The volume of the toolbox
V=10*7*3
V=210 in^3
Let us double the volume and see
2V= 210*2
=420 in^3
Let us also double the individual dimensions
Length=20
Width=14in
Height=6in
V= 20*14*6
V=1680 in^3
Hence the volume will be different, she will not be correct
Brian needs to find the value of a number, a, so that when (x^2+3x) is added to the binomial (3x^2+ax), the sum simplifies to 4x^2+12x. What is the value of a?
Answer:
a = 9
Step-by-step explanation:
First we need to add (x^2+3x) to (3x^2+ax),
(x^2+3x)+(3x^2+ax)
Expand
= x^2+3x+3x^2+ax
Collect the like terms
= x^2+3x^2+3x+ax
= 4x^2 + 3x + ax
= 4x^2+(3+a)x
Equate the solution to 4x^2+12x
4x^2+(3+a)x = 4x^2+12x
Comparing the like terms on both sides
(3+a)x =12x
3 + a = 12
a = 12 - 3
a = 9
Hence the value of a is 9

Angle of a triangle measures 115° the other two angles are in the ratio of 4:9 what are the measures of those two angles
Answer:
20, 45
Step-by-step explanation:
A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles must add up to 65.
The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9
A ratio partition parts of something. We can add the ratio intergers to find it full length.
4+9=13.
Divide 65/13=5.
Multiply 5x4 and 5x9 serpately.
We get 20 and 45

Find x in the following ,giving reasons
Answer:
x = 22.5
Step-by-step explanation:
→ Remember how many degrees the point to a radius is
90°
→ Set up an equation
x + 3x = 90
→ Simplify
4x = 90
→ Divide both sides by 4
x = 22.5
A number is decreased by 15% and the resulting number is then increased by 20%. That final number is what percent of the original number?
Answer:
The final final number becomes 102 % of the original number
Step-by-step explanation:
Let the initial number be 100
After decreasing 15%, the new number is 100-15% of 100 = 85
The resulting number is then increased by 20%. The new number will be
85 + 20% of 85 = 85 + 17 = 102
The final final number becomes 102/100 * 100 percent of the original number
The final final number becomes 102 % of the original number
