With x^2 the x-intercept is (0,0) because it meets at the origin. there are two x intercepts for g(x)=x^2-7 but only one x-int for f(x)=x^2. g(x) SHIFTED DOWN by 7 since the y-int is -7

On a math test 12 students earned an a this number is exactly 25% of the total number of students in the class how many students
statuscvo [17]

Answer:

48 students.

Step-by-step explanation:

25% of total students = 12

suppose,

total students= x

so,

25% of x=12

(25/100)*x=12

25*x=(12*100)

x=1200/25

x=48

therefore,

x= total students= 48.

Brendan earns 25% more than his regular hourly rate d when he works on holidays. Write an expression to represent the hourly rat
Tanya [424]

Answer:

The expression that represents hourly rate Brendan earns working on a holiday is 1.25d.

Step-by-step explanation:

Given:

Regular hourly rate = d

Percent extra Money earned on holidays = 25% more

We need to find expression represent the hourly rate Brendan earns working on a holiday.

Solution:

Extra money earned on holidays can be calculated by Percent extra Money earned on holidays multiplied by Regular hourly rate.

framing in equation form we get;

Extra money earned on holidays = \frac{25}{100}d=0.25d

Now we will find hourly rate Brendan earns working on a holiday.

hourly rate Brendan earns working on a holiday can be calculated by sum of Regular hourly rate plus Extra money earned on holidays.

framing in equation form we get;

hourly rate Brendan earns working on a holiday = d+0.25d=d(1+0.25) =1.25d

Hence The expression that represents hourly rate Brendan earns working on a holiday is 1.25d.

PolarNik [594]
No.
EXPLANATION:
To tackled this problem we should find an equivalent denominator.

We find that the lcm ( lowest common denominator ) is 20.

1 x 5 = 5
4 x 5 = 20

2 x 4 = 8
5 x 4 = 20.

so the answer is no.

The ratio of cats to dogs at the animal shelter is 2:5.If there are 35 animals total,how many cats are there?
marissa [1.9K]
Set up a proportion to describe this relationship. So, for every 2 cats, there is five dogs. Therefore, “c” can represent your unknown quantity for every 35 animals.

2/5 = c/35

Cross multiply, multiplying the numerator/top number of the first fraction/ratio, by the denominator/bottom number in the second fraction/ratio.

2 • 35 = 70

Then, Cross multiply, multiplying the numerator/top number of the second fraction/ratio, by the denominator/bottom number in the first fraction/ratio.

C • 5 = 5c

So, now the problem shows both products as equal to each other.

70 = 5c

To solve for the variable, “c”, you must isolate the variable, by performing the opposite/inverse operation of multiplication, since that will undo the multiplication, for the variable to stand alone. Therefore, divide both sides of the equation by 5.

70/5 = 5c/5

14 = c

So, there is 14 cats out of 35 animals.
