Henry has q5 lawns mowed out of total 60 lawns what percent of the laws does. Henry still have to mow
Answers
Answer:
Henry still has to mow 75% of the laws.
Step-by-step explanation:
It is given that Henry has 15 lawns mowed out of a total of 60 lawns.
We need to find: What percent of the lawns do Henry still have to mow?
Henry has 60 lawns in total.
He mowed 15 out of them.
The percentage of lawns mow = [tex]\frac{15}{60} \times 100=25 \%[/tex]
Henry mowed 25% of total lawns.
The percent of laws still have to mow = 100%-25%
The percent of laws still have to mow = 75%
Hence, Henry still has to mow 75% of the laws.
Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation
Answers
Answer:
To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.
Step-by-step explanation:
Consider the provided information.
Roots of the equation is x-intercepts or zeros of the given equation.
So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.
Thus, we can find the roots of a quadratic function, by putting f (x) = 0.
Now, let (x-a)(x-b) is the factor of any quadratic equation.
To find the roots of the quadratic function we will put our factor equal to 0.
[tex](x-a)(x-b)=0[/tex]
Now by the zero product property either x-a=0 or x-b=0
[tex]x-a=0[/tex] then [tex]x=a[/tex]
or
[tex]x-b=0[/tex] then [tex]x=b[/tex]
So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

starbucks: 24 / 336 = $0.07
1 ounce sells for about $0.07
circle k: 16 / 240 = 0.066 = (rounded) 0.07

The shifting of graph depends on value of b.
[tex]y = mx + b[/tex]
If b > 0, the graph shifts up.
If b = 0, the graph passes origin point.

The only thing that's matter if the graph shifts up or down is about if the value of b is in negative or positive.

What is the gross profit margin?The gross profit margin is a profitability raio. Profitability ratios measures the efficiency with which a company generates profit from its asset. Gross profit margin measures the return on sales.
Gross profit margin can be calculated by dividing the gross profit (difference between revenue and cost of goods sold) by revenue (Net sales). It could be expressed as a percentage by multiplying by 100.
Therefore, Gross profit margin = (gross profit ÷ net sales) x 100
Gross profit = $3,320
Net sales = $4,350
Gross profit margin = ($3,320÷$4,350) * 100
0.763 * 100 = 76.3%
4,350 - 3,320 = 1030
That would be 870 dollar.

A movie theater sells adult tickets for $6 each. Senior citizens receive a discount of $3. One evening the theater sold 400 tickets and took in $2070 in revenue. How many tickets were sold to senior citizens?
Answers
Answer:
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Step-by-step explanation:
First, we need to establish a system of equations:
x= number of adults tickets
y= number of senior citizen tickets
x + y= 400
6x + 3y= 2,070
Now, we isolate x in one equation and substitute the value in the other:
x= 400 - y
6*(400 - y) + 3y = 2,070
2,400 - 6y + 3y = 2,070
330 = 3y
110 = y
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Prove:
290 + 110= 400
6*290 + 3*110= 2,070

Find angle x and y. Please show step by step process.
Answers
Answer:
x = 60, y = 25
Step-by-step explanation:
Δ ABC has 3 congruent sides and is equiangular, thus
the 3 angles are congruent, all 60°
x = 60
∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then
∠ CBD = 180° - 60° = 120°, so
y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle
y = 25
