9 × 1/5 is the answer greater than or less than 9 and why

Vikentia [17]

When u multiply by a fraction, you get a smaller number. Multiplication means<span> “of,” especially with fractions. So 0.2 × 9 means, “0.2 of nine”—and that’s smaller than nine. Hope that helps

Find the missing b for a trapezoid with a=68, h=4, b=21

MAVERICK [17]

We will have to use the formula for the area of a trapezoid on this problem, which is ( $b_1$ and $b_2$ are the bases of the trapezoid and $h$ is the height):

$\dfrac{b_1 + b_2}{2} \cdot h$

All we need to do is substitute the information we are given into our formula:

$\dfrac{21 + b_2}{2} \cdot 4 = 68$

Now, let's just simplify the equation:

$\dfrac{21 + b_2}{2} \cdot 4 = 68$

$\dfrac{21 + b_2}{2} = 17$

$21 + b_2 = 34$

$b_2 = 13$

The missing base has a length of 13 units.

Answer:

<h2>y + 4 = x</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points A(0, -4) → b = -4 and B(6, 2).

Calculate the slope:

$m=\dfrac{2-(-4)}{6-0}=\dfrac{6}{6}=1$

Put the value of m and of b to the equation:

$y=1x-4$ <em>add 4 to both sides</em>

$y+4=x$
