Answer:

  0.15 dL

Step-by-step explanation:

The volume of the bar is ...

  V = LWH

  V = (5 cm)(3 cm)(1 cm) = 15 cm³

1 dL = 100 cm³, so this volume is ...

  (15 cm³)(1 dL)/(100 cm³) = 0.15 dL

The bar will displace 0.15 deciliters.

Step-by-step explanation:

An expression is defined as a set of numbers, variables, and mathematical operations. The given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let the unknown number be represented by x.

The product means multiplication, therefore, we need to double or multiply the product or multiplication of eight and x.

Thus, The given statement in the form of an expression can be written as,

2(8 × x)

= 2(8x)

= 16x

Hence, the given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

Answer: See explanation

Step-by-step explanation:

Do you mean the greatest common factor (GCF), or the lowest common multiple (LCM).

If you mean GCF, then it is 1 because 7 is a prime number and has two facotrs (1 and itself) and since 9 isn’t divisible by 7, the GCF must be 1.

If you mean the LCM, the answer is 63. Using prime factorisation, we find the lowest prime factor of both numbers:

9 = 3^3

7= 7^1

Then, we multiply these together to give 63.

You cannot have a GCM, because you can’t find a greatest common multiple as numbers go on forever.

I hope this helps!

Step-by-step explanation:

f(v) means your x value is v so substitute X=v in f(x)

[tex]f(v) = 3 \frac{v}{v} + 2 \\ 3 + 2 \\ 5[/tex]

Answer:

x = 81 degrees

<z = 99 degrees

<y = 68 degrees

Step-by-step explanation:

<x = 180 - 36 - 63 = 81 degrees

<x + <z = 180 degrees

81 + <z = 180

<z = 180 - 81

<z = 99 degrees

<y = 180 - 99 - 13

<y = 68 degrees

Answer:

∠ 5 = 84°

Step-by-step explanation:

Complementary angles sum to 90° , then

∠ 5 + ∠ 6 = 90° , that is

∠ 5 + 6° = 90° ( subtract 6° from both sides )

∠ 5 = 84°

Answer:

-32

Step-by-step explanation:

if we multiply - 2 and -6 it becomes positive so it will be 12.

-2 multiply 22 will be -44

12 - 44 is -32.

answer : -32

you distribute so you do -2 times -6 which is 12. then -2 times 22 which is -44.

you end up with 12 - 44, which equals -32.

Answer:

w = 20

Step-by-step explanation:

2 (3w - 6) = 5w + 8

distribute the 2

6w - 12 = 5w + 8

subtract 5w from both sides

w - 12 = 8

add 12 to both sides

w = 20

Answer:

The value of w is 20.

Step-by-step explanation:

Solution :

[tex]{\longmapsto{\tt{2(3w - 6)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{(3w \times 2 )- (6 \times 2)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{(6w)- (12)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{6w - 12=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{6w - 5w = 8 + 12}}}[/tex]

[tex]{\longmapsto{\tt{w = 20}}}[/tex]

Hence, the value of w is 20.
