What is five multiplied by one tenth plus seven multiplied by one hundredth plus three multiplied by one thousandth written in standard form? HELP I Will give brainleist

Answer:

1 . 4 hrs , 2 . total 400 miles because the first train had travelled 160 miles and 2nd one had travelled 240 miles

Step-by-step explanation:

in 1. use relative motion concept I. e. you sir on 1st train and put velo. of same mag. and in oppo. direction on the train on which you have sit and do the same with the velocity only with 2nd train means you stop the train on which you are sitting and put the velocity of the train on which you are sitting on 2nd train but in oppo. direction , so now the relative velocity comes out to be 20 mph and then apply formula time = Srel / Vrel and here we can find S rel by multiplying the velo. of 1st train by given time I. e. 2 hrs and in 2. multiply the time calculated by us by the velocity of both trains and by which you get the dist. travelled by both trains and then add them to get final answer.

Answer:

It is 9

Step-by-step explanation:

[tex]4(y + z)[/tex]

when y is 5, z is 4

substitute:

[tex] = 4(5 + 4) \\ = 36[/tex]

Answer:

y=5 z = 4 - substitution

4 (5 + 4) = 4 (9) = 36

Answer:

A. y ≤ 1

Step-by-step explanation:

according to the graph, the coordinates of maximum value is (-3, 1) and besides the graph towards down, so, the range of the function is y ≤ 1

Answer:

6 songs

Step-by-step explanation:

27 divided by 4 1/2 or 4.5 equals 6 which mean they sang six songs.

Answer:

Answer:

See below.

Step-by-step explanation:

The top number is the product (multiplication) of the two side numbers. The bottom number is the sum (addition) of the two side numbers.

10÷2=5

5+2=7

6÷3=2

2+3=5

4÷-4=-1

-1-4=-5

this is the pattern

Step-by-step explanation:

(2x-1)(3x+2) = 0

6x + 4x - 3x - 2 = 0

7x - 2 = 0

7x = 2

X = 2/7

Fill in this X for the 2 formulas, I'll do the first one:

2 * 2/7 - 1 =.....

Then take the 2 answers you get and multiply them with each other so you get the surface size (length * width)

Answer:

Angle ABC = 110 degrees

Step-by-step explanation:

Set angle ABC equal to the two parts and solve for x

17x + 8 = 42 + 12x - 4

17x + 8 = 12x + 38

5x = 30

x = 6

Plug in x to angle ABC and solve

17(6) + 8 = 110

Answer:

x = 2

Step-by-step explanation:

h(x) = -3x + 2

In this question, h(x) has the same meaning as y, so though this is not a standard practice, rewrite the question as

y = -3x + 2

What the question is telling you is that y = - 4

-4 = -3x + 2                  Subtract 2 from both sides

-4-2 = -3x                    Combine

-6 = - 3x                       Divide by - 3

-6/-3 = x

x = 2

Answer:

265x{2} + 40x

Step-by-step explanation:

Squared mean to multiply the number times itself. So 15x times 15x.

[tex]15x^{2} = 225x[/tex]{2}

Then the problem says to add, but because one is squared and th other is not, they cannot be combined. So the answer is:

[tex]225x{2} + 40x

Answer:

see below

Step-by-step explanation:

15x^2 + 40x

These are not like terms so they cannot be combined.

If you mean

(15x) ^2 + 40x

(15x * 15x) + 40x

225x^2 + 40x

They are still not like terms so they cannot be combined.

Answer:

[tex] \frac{ay}{x} - dx = wx [/tex]

multiply x through out:

[tex]ay - {dx}^{2} = w {x}^{2} \\ {wx}^{2} + {dx}^{2} = ay[/tex]

factorise out x²:

[tex] {x}^{2} (w + d) = ay \\ {x}^{2} = \frac{ay}{w + d} [/tex]

take square root on both sides:

[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{ay}{w + d} } \\ \\ x = \sqrt{ \frac{ay}{w + d} } [/tex]

Step-by-step explanation:

the biggest obstacle is usually a division by x.

so, let's get rid of it by multiplying both sides of the equation by x

ay - dx² = wx²

then

ay = wx² + dx² = (w+d)x²

y = (w+d)x²/a = x² × (w+d)/a

Answer: 4x² + 4xy - 3y²

Concept:

When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:

Solve:

Given

(2x - y) (2x + 3y)

Expand parentheses and apply the FOIL method

=4x² + 6xy - 2xy - 3y²

Combine like terms

=4x² + (6xy - 2xy) - 3y²

Answer:

measure of both angle is 66

Step-by-step explanation:

vertical angles are equal so,

6x+15=4x+32

6x-4x=32-15

2x= 17

X=8.5

now,

4X+32

= 4×8.5 +32

= 66
