Let the <C=x

We know in a triangle

☆Sum of angles=180°

$\\ \sf\longmapsto 51+26+x=180$

$\\ \sf\longmapsto 77+x=180$

$\\ \sf\longmapsto x=180-77$

$\\ \sf\longmapsto x=103°$

how many bricks can my truck carry in a full load if each brick weighs 4 pounds 14 ounces and my truck can carry a 3/4 ton load

aleksklad [387]

Answer:

The number of bricks a truck can carry in full load is 308 .

Step-by-step explanation:

Given as :

The weight of each brick = 4 pounds and 14 ounce

The total load a truck can carry = $\dfrac{3}{4}$ tons

Let The number of bricks truck can carry = n bricks

Now, According to question

∵ 1 ounce = 0.0625 pounds

∴ 14 ounce = 0.0625 × 14 = 0.875 pounds

So, Total weight of each brick = 4 pounds + 0.875 pounds = 4.875 pounds

Again

∵ 1 pound = 0.0005 tons

∴ 4.875 pounds = 0.0005 × 4.875 = 0.0024375 tons

Now, Again

The total load a truck can carry = $\dfrac{3}{4}$ tons = 0.75 tons

And The weight of each brick = 0.0024375 tons

So, The number of bricks = $\dfrac{\textrm total load a truck can carry}{\textrm Total weight of each brick}$

I.e n = $\dfrac{0.75}{0.0024375}$

∴ n = 307.69 ≈ 308

So, The number of bricks can truck carry = n = 308

Hence, The number of bricks a truck can carry in full load is 308 . Answer

What is the value of r for 19 and 20?

nata0808 [166]

Answer:

19.) r = -4 20.) r = 1

Step-by-step explanation:

19.) Because we know the slope and have some points, we can use point-slope form to find the equation.

Point-slope form is:

y - y1 = m(x - x1)

Substitute the numbers into the equation:

y - 3 = 7/6(x - 1)

y - 3 = 7/6x -7/6

y = 7/6x + 11/6

Now that we know the equation, we can put in the x value to find the y (In this case, y = r):

r = 7/6(-5) + 11/6

r = -35/6 + 11/6

r = -4

20.) Because the slope is undefined, that means on the graph, the line will appear straight and vertical. This means the equation will be something like x = a number.

We have the point (1,4). Since we know that the x value will never change, we know that r will have to equal 1 as well.

r = 1

It is believed that 3/4 of our dreams involve people that we know. Write an expression to describe the number of dreams that fea

professor190 [17]

3/4 of dreams = 3/4 of 'd'

The expression is $\frac{3}{4}d$

When d = 28
Number of dreams = $\frac{3}{4}(28)= \frac{3*28}{4}=21$

Answer: 21 dreams
