Write a quadratic equation that has the solutions: 4 and -7
Answer:
y = ( x-4)(x+7)
Step-by-step explanation:
When we know the zeros of the equation, we can write the equation in the form
y= a(x-z1) (x-z2) where a is a constant and z1 and z2 are the zeros (solutions)
y = a( x-4)(x--7)
y =a( x-4)(x+7)
Since its says write an equation, we can pick a and I will let a=1
y = ( x-4)(x+7)

I need help but they are getting confused with the z as a 2 please don’t get confused the z is a z
Step-by-step explanation:
everything can be found in the picture
Answer:
w = - (7/2) z
Step-by-step explanation:
5w + 9z = 2z + 3w
Subtract 3w from both sides
2w + 9z = 2z
Subtract 9z from both sides
2w = -7z
Divide both sides by 2
w = - (7/2) z
A John and Kate share £180 in the ratio
2:3. Work out how much money each person
receives.
Answer:
John's share = £72
Kate's share = £108
Step-by-step explanation:
Given:-
Share amount of John and Kate = £180
Share amount given in ratio = 2:3
Find:-
Work out how much money each person
receives.
Solution:-
Ratio:
John Kate
2 : 3
Add the ratio:
2 + 3 = 5
Divide the total amount from the added ratio:
180 / 5 = 36
Each part of the ratio is 36.
John's amount:
{multiply 36 with 2}
36 × 2 = £72
Kate's amount:
{multiply 36 with 3}
36 × 3 = £108

Chef Antonio works at a Latin restaurant and doing a great job. During his yearly evaluation, the owner increased his salary from $42,500 to $46,000. What is the percent of increase, to the nearest whole percent, in Chef Antonio's salary?
Answer:
8%
Step-by-step explanation:
To find the percent change, we first have to find the amount changed, which is (46000-42500) = 3500. Then, we find what percentage that is of the original amount. Remember that when calculating percentage change, it's important to calculate change with respect to the initial value.
To find the percentage, we can divide 3500 by 42500, and multiply that by 100, resulting in 8 being our nearest whole percent

Answer:
3.3333 (repeating)
Step-by-step explanation:
He has 50 missing assignments and 15 days to do them.
So you do 50 missing assignments divided by 15 days, to see how many assignments a day he would have to do.
50 / 15 = 3.33 (repeating)
Answer:
3.333333333333333
Step-by-step explanation:
You will have to divide 15 by 50 to get the answer. That will give you 3.333333333333333 which is your answer.

Step-by-step explanation:
The conditional relative frequency table was calculated by row using data from a survey of one station’s television programming. The survey compared the target audience with the type of show, either live or recorded, over a 24-hour time period.
A 4-column table with 3 rows titled television programming. The first column has no label with entries adult, children, total. The second column is labeled live with entries 0.625, 0.5, nearly equal to 0.583. The third column is labeled recorded with entries 0.375, 0.5, nearly equal to 0.417. The fourth column is labeled total with entries 1.0, 1.0, 1.0.
Which is the best description of the value 0.375 in the table?
Given that the program was targeted at adults, there is a 37.5% chance that it was recorded.
Given that the program was recorded, there is a 37.5% chance that it was targeted at adults.
37.5% of the programs are targeted at adults.
37.5% of the programs are recorded.
Answer:
37.5% of the programs are targeted at adults
Step-by-step explanation:
The following figure shows the given four column table for the target audience of television programming
[tex]\begin{array}{lllc}&Television \ Programming \\& Live&Recorded&Total\\Adult&0.625&0.375&1.0\\Children&0.5&0.5&1.0\\Total&\approx 0.583& \approx 0.417&1.0\end{array}[/tex]
From the table, we have that the best description of the value 0.375 in the table is that the percentage of television program targeted at adults is 37.5%
Answer:
The answer is a “Given that the program was targeted at adults, there is a 37.5% chance that it was recorded”

What is the area of triangle ABC?
3 square units
O 7 Sguare units
11 square units
15 square units
Answer:
3
Step-by-step explanation:
base = 4-1
= 3
height = 3-1
= 2
Area = 1/2 (b)(h)
= 1/2 (3)(2)
= 3
therefore the answer is 3 square unit
Given two similar cylinders with a height ratio of 2:3 what is the ratio of their volumes?
Answer:
8 : 27
Step-by-step explanation:
The ratio of the volumes is the ratio of the scale factor cubed
2^3 : 3^3
8 : 27
Answer:
8 : 27
Step-by-step explanation:
Given 2 similar cylinders with height ratio = a : b , then
ratio of volumes = a³ : b³
Here height ratio = 2 : 3
ratio of volumes = 2³ : 3³ = 8 : 27

Write "five thousand six hundred eighty-five and twelve hundredths" in expanded form
Answer:
56851200
Step-by-step explanation:
The expanded form of the number is 5000 + 600+ 80 + 5 + 0.1 + 0.02 and the number is 5685.12
What is number?A number is a mathematical entity that can be used to count, measure, or name things. For an example, 1, 2, 56 etc. are the numbers.
It is given that:
The word expression:
"five thousand six hundred eighty-five and twelve hundredths"
The number would be:
= 5685.12
In the expanded form the number can be written as:
The expanding form can be used to indicate the value of each digit in a number in arithmetic.
Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.
Expanded Form:
5685.12 = 5000 + 600+ 80 + 5 + 0.1 + 0.02
Thus, the expanded form of the number is 5000 + 600+ 80 + 5 + 0.1 + 0.02 and the number is 5685.12

Use numerals instead of words
Answer:
Step-by-step explanation:
Put in the 3 and 4 so it is the square root of 3^4 - -6^2
The square root of 3^4 + 6^2
The square root of 3^4 is 3^2 so
9 + 6^2
=> 9 + 36
=> 45
45 in numerals is XLV
Alice, Bernice, and Carol have £600 altogether. The ratio of Alice’s money to Bernice’s money is 3:7. Carol has £60 more than Alice. What is the amount of money each girl got?
Answer:
Alice - £124.62
Bernice - £290.77
Carol - £184.62
Step-by-step explanation:
Let the amount of money Alice has be a. This way, the sentence "The ratio of Alice’s money to Bernice’s money is 3:7." can be translated into a proportion:
Alice's money / Bernice's money = 3 / 7
We can substitute Alice's money with a, and cross multiply and solve for Bernice's money:
a / Bernice's money = 3 / 7
7a = 3(Bernice's money)
Bernice's money = 7/3 a
Now, we can represent Carol's money in terms of Alice's money, she has 60 more, or a + 60. We can create can equation to represent the total:
Alice's money + Bernice's money + Carol's money = total
We can plug in what we have and solve for a:
a + 7/3 a + a + 60 = 600
13/3 a = 540
a = 124.62
This means Alice has £124.62
Bernice has 7/3 a amount of money, so we can substitute the value of a to get Bernice has 7/3 (124.62), or £290.77
We can do the same for Carol who has 60 more, 124.62 + 60 is £184.62
