Fine the equation of the line that is perpendicular to the given line and passes through the given point. Enter the right side o

Kipish [7]

Answer:

$y=-\frac{4}{7} x+\frac{55}{7}$

Step-by-step explanation:

Change the given equation to slope-intercept to get $y=\frac{7}{4}x-\frac{1}{4}$ . When you multiply the slopes of perpendicular lines, you get -1. -1 divided by $\frac{7}{4}$ is $-\frac{4}{7}$ . The slope of the new line is then $-\frac{4}{7}$ . The perpendicular line passes through (5, 5) so you can have the equation $5=-\frac{4}{7} (5)+b$ . Simplifying gets $b = \frac{55}{7}$ . So now the final equation for the perpendicular line is $y=-\frac{4}{7} x+\frac{55}{7}$

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

stich3 [128]

Answer:

The surface area of the paperweight is $SA=8.3\ in^2$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

so

<em>Find the area of its triangular base</em>

$SA=\frac{1}{2}(2)(1.7)$

$SA=1.7\ in^2$

<em>Find the area of its three triangular lateral faces</em>

$SA=3[\frac{1}{2}(2)(2.2)]$

$SA=6.6\ in^2$

Adds the areas

$SA=1.7+6.6$

$SA=8.3\ in^2$

Dakota has \dfrac4{10} \text { kg} 10 4 kgstart fraction, 4, divided by, 10, end fraction, start text, space, k, g, end text o

Savatey [412]

Answer:

There are <u>2.22 grams</u> of clay are in each pot.

Step-by-step explanation:

Given:

Dakota has 4/10 kg of clay. He divides the clay to make 888 equal-sized pots.

Now, to find the number of grams of clay are in each pot.

Dakota has clay = $\frac{4}{10} \ kg.$

So, by using conversion factor we convert it into grams:

$\frac{4}{10} \times 1000\\\\=\frac{4000}{10} \\\\=400\ grams.$

Quantity of clay he has = 400 grams.

Number of equal-sized pots to make = 888.

Now, to get the quantity of grams of clay are in each pot we divide number of equal-sized pots to make by quantity of clay he has:

$\frac{888}{400}$

$=2.22\ grams.$

Therefore, there are 2.22 grams of clay are in each pot.
