Jonathan looked at the picture frame below and computed the following sum: 8 + (-4). What value did he find?

Step-by-step explanation:

Let the length be x

7% of x = 200ft

7/100 × x = 200

7x/100 = 200

7x = 200 × 100

7x = 20000

x = 20000/7

x = 2,857.14

Step-by-step explanation:

Basically, the question is asking what number multiplied by 0.07 is equal to 200?

2857.14286 ft (round as necessary)

the way you can do this:

x(0.07)=200

isolate x by dividing 200 by 0.07 (200/0.07=2857.14286 ft)

Your answer should be B: 2^1 I'm pretty sure.

Answer:

The answer is b  2^1.

Answer: x = 1/4

Step-by-step explanation:

-9x + 6 = -x + 4

+x           +x

-8x + 6 = 4

      -6    -6

-8x = -2

divide by -8 on both sides

x = 2/8

simplify

x = 1/4

Answer:

Step-by-step explanation:

-9x + 6 = -x + 4

-9x + x = 4 - 6

-8x = -2

x = 2/8

x = 1/4

Answer:

72,630

Step-by-step explanation:

630 + 7.2 x 10^4= 72,630

The value of the  product of 630 & 7.2×10⁴ is 4.536 x 10⁷.

The standard form for a number is a method by which we write number in a format like b×10ˣ. The value of b should be in between 0 to 10.

To multiply two numbers in scientific notation, we can first multiply their coefficients and then add their exponents.

630 can be written as 6.3 x 10² in scientific notation.

7.2 x 10⁴ is already in scientific notation.

So, the product of 630 and 7.2 x 10⁴ can be found by multiplying the coefficients and adding the exponents:

(6.3 x 10²) x (7.2 x 10⁴)

= (6.3 x 7.2) x (10² x 10⁴) (using the distributive property of multiplication)

= 45.36 x 10⁶ (multiplying the coefficients)

= 4.536 x 10⁷ (simplifying the exponent by moving the decimal point to the left)

Therefore, the product of 630 and 7.2 x 10⁴ is 4.536 x 10⁷.

Answer:

[tex]\huge\boxed{x=20}[/tex]

[tex]\huge\boxed{H = 58, I = 71, J = 51}[/tex]

Step-by-step explanation:

In order to find the measure of our angle, we have to note angle relationships.

All angles in a triangle will add up to 180°

This means all the angles in this triangle will equal 180, or:

[tex](4x - 9) + (3x - 2) + (3x-9) = 180[/tex]

We can simplify this equation down to find the value of x.

Combine like terms:

[tex]10x - 20 = 180[/tex]

Add 20 to both sides:

[tex]10x = 200[/tex]

Divide both sides by 10:

[tex]x = 20[/tex]

Now that we know the value of x, we can substitute it into the equation for each angle to find it's value.

m∠H:

[tex]3x-2\\3(20)-2\\60-2\\\\58[/tex]

m∠I

[tex]4x-9\\4(20)-9\\80-9\\\\71[/tex]

m∠J

[tex]3x-9\\3(20)-9\\60-9\\\\51[/tex]

To further prove this is right, we would know that all the angles add up to 180°.

[tex]51+71+58=180[/tex], so we should be right.

The vertices of the square [tex]B'C'D'E'[/tex] are [tex]B'(x, y) = (6,7)[/tex], [tex]C'(x,y) = (2, 6)[/tex], [tex]D'(x,y) = (3,2)[/tex] and [tex]E'(x,y) = (7,3)[/tex]

Step-by-step explanation:

From Geometry we notice that a reflection with axis of symmetry on y-axis is represented by the following formula:

[tex](x',y') = (-x, y)[/tex], [tex]\forall \,x,y\,\in\mathbb{R}[/tex]

Thus, the vertices of the square [tex]B'C'D'E'[/tex] are [tex]B'(x, y) = (6,7)[/tex], [tex]C'(x,y) = (2, 6)[/tex], [tex]D'(x,y) = (3,2)[/tex] and [tex]E'(x,y) = (7,3)[/tex]

   Coordinates of the image square B'C'D'E' after reflecting the square BCDE across y-axis will be B'(6, 7), C'(2, 6), D'(3, 2), E'(7, 2).

If a point (x, y) is reflected across y-axis, rule to be followed,

(x, y) → (-x, y)

Following this rule coordinates of image square B'C'D'E' will be,

B(-6, 7) → B'(6, 7)

C(-2, 6) → C'(2, 6)

D(-3, 2) → D'(3, 2)

E(-7, 2) → E'(7, 2)

      Therefore, vertices of the image square will be B'(6, 7), C'(2, 6), D'(3, 2), E'(7, 2).

Answer:

  a)  y = 2x +4

  b)  y = 1/2x +4

  c)  y = -2x +11

Step-by-step explanation:

The given equations are in slope-intercept for, so we can read the slope directly from the equation. It is the x-coefficient.

We can then write an equation of a parallel line using the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . for a line with slope m through point (h, k)

If you like, you can rearrange this to "slope-intercept" form. Add k and simplify.

  y = mx +(k -mh)

__

a) m = 2, (h, k) = (3, 10)

  y = 2x +(10 -2·3)

  y = 2x +4

__

b) m = 1/2, (h, k) = (0, 4)

  y = 1/2x +(4 -(1/2)·0)

  y = 1/2x +4

__

c) m = -2, (h, k) = (4, 3)

  y = -2x +(3 -(-2)(4))

  y = -2x +11

Answer:

101

Step-by-step explanation:

We look at the tenths place if we want to round to the whole number, and since the tenths place is 5, we round up.

The answer is 101. Any number that is 5 or higher can round the number in a higher number place (by one) it up by one. In this case, we are rounding the tenths place to the ones place. 5 can be used to round the number in the ones place up by one. Therefore 100.552 -> 101.
