Answer:

9 3/7

Step-by-step explanation:

4 2/7 = 30/7

2 1/5 = 11/5

30/7 x 11/5 = 330/35

Answer:

we can write

42/7 as 30/7

and

21/5 as 11/5

now

$\frac{30}{7} \times \frac{11}{5} \\ = \frac{6}{7} \times 11 \\ = \frac{66}{7}$

we can write 66/7 as 93/7

hence,

option D is correct.

hope this answer helps you dear....take care!

Crank

Answer:

The radius is 6.1 cm

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

There is a typo in the problem.

We know the volume

950 = 4/3 (3.14) r^3

Multiply each side by 3/4

3/4 *950 = 3.14 r^3

712.5 = 3.14 r^3

Divide each side by 3.14

712.5/3.14 = r^3

226.910828 = r^3

Take the cube root of each side

226.910828 ^ (1/3) = r^3 ^ 1/3

6.099371323 = r

The radius is 6.1 cm

Find The value of x, y and z

Ratling [72]

Answer:

x = 18 ; y = 10 ; z = 102°

Step-by-step explanation:

The triangle in the pic is an isosceles triangle.

As it is an isosceles triangle , it's two sides will be equal .

$= > 3x - 42 = 12$

$= > 3x = 42 + 12 = 54$

$= > x = \frac{54}{3} = 18$

Also, both the base angles will be equal.

$4y - 1 = 39$

$= > 4y = 39 + 1 = 40$

$= > y = \frac{40}{4} = 10$

According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,

$z + 39 + 39 = 180$

$= > z + 78 = 180$

$= > z = 180 - 78 = 102$

In some country the budget for defense exceeded the budget for education by $660.4 billion. If x represents the budget for edu

photoshop1234 [79]

Answer:

The budget for defense can be represented as x + 660.4

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Budget for education is $ 660.4 billion less than budget for defense in some country

x = represents the budget for education, in billion of dollars

2. How can the budget for defense be represented?

x = represents the budget for education, in billion of dollars

x + 660.4 = represents the budget for defense, in billion of dollars also

The correct answer is that the budget for defense can be represented as x + 660.4
