7. What's the sum of 2/5 and 2/4?

Mathematics
2 answers:
NISA [10]3 years ago
5 0

Step-by-step explanation:

2/5+2/4 (find common denominator)

The common denominator is 20

2/5 is 8/20 (multiply by 4)

2/4 is 10/20 (multiply by 5)

8/20+10/20 is 18/20

If you simplify 18/20 this would by 9/10 if you divide by 2

so the total is 18/20 or 9/10 simplified

Hope this helps!!!!

Have a nice day :)

Answer: 9/10

Step-by-step explanation:

2/5 + 2/4

Multiply the two denominators (4×5)= 20

Divide 5 by 20= 4, then multiply by 2= 8

Divide 4 by 20= 5, multiply by 2= 10

8 +10/20 = 18/20; divide by a common value of 2 to simplify the fraction

18/20=9/10

I hope this helps.

The axis of symmetry for the graph of the function is f(x) = x2 + bx + 10 is x = 6. What is the value of b?
joja [24]

Answer:

b=-12

Step-by-step explanation:

we have

f(x)=x^{2}+bx+10

we know that

The equation of a vertical parabola into vertex form is equal to

y=a(x-h)^{2} +k

where

(h,k) is the vertex of the parabola

and the axis of symmetry is equal to x=h

In this problem we have the axis of symmetry x=6

so

the x-coordinate of the vertex is equal to 6  

therefore

For x=6+1=7 -----> one unit to the right of the vertex

Find the value of f(7)

f(7)=7^{2}+b(7)+10

f(7)=59+7b

For x=6-1=5 -----> one unit to the left of the vertex

Find the value of f(5)

f(5)=5^{2}+b(5)+10

f(5)=35+5b

Remember that

f(5)=f(7) ------> the x-coordinates are at the same distance from the axis of symmetry

so

59+7b=35+5b ------> solve for b

7b-5b=35-59

2b=-24

b=-12

prem gave 1/3 of his property for charity of the rest he gave 2/3 to his wife and rest divided equally between his son and daugh
Anna11 [10]

Given parameters:

Fraction given to charity = \frac{1}{3}

Fraction given to wife = \frac{2}{3}

Unknown:

Fraction given to son and daughter =?

Solution:

Let the total property  = x

    Fraction given to charity  = \frac{1}{3} x

    Fraction given to wife  = \frac{2}{3} x

The remaining was given to son and daughter = F

    So;

     Total property  = fraction given to charity + fraction given to wife + fraction given to son and daughter

         x  = \frac{1}{3} x + \frac{2}{3} x + F

            F = x - (\frac{1}{3} x + \frac{2}{3} x)

            F = 0

The son and daughter will not inherit anything

jennifer invests $2,302 in a money market account. the account pays 2.1% simple interest annually. if she doesn’t add or subtrac
alexandr402 [8]

Jennifer would earn more than $200. She would earn $230.02 over the period.

<h3>What is the simple interest that Jennifer would earn?</h3>

Simple interest is a type of interest paid only on the money invested.

Simple interest = amount invested x interest rate x time

2302 x 5 x 0.021 = $230.20
