What is the value of y? Enter your answer in the box. B (5x)° A (2 y+20)° C 40°

WARRIOR [948]

Answer:

y = 40°

Step-by-step explanation:

The triangle in the picture is an isosceles triangle because of the markings on the side (they show that two sides are congruent).

An isosceles triangle not only have a pair of congruent sides, but also have a pair of congruent angles.

So,

5x = 40

Solve for x,

x = 40 ÷ 5

x = 8

5x = 40

5(8) = 40

40 = 40

Now we know the two angles. We then find the last angle containing y.

We know that the total angle measurement of the triangle is 180°.

Set up the equation,

40 + 40 + 2y + 20 = 180

Solve for y,

80 + 2y + 20 = 180

100 + 2y = 180

2y = 180 - 100

2y = 80

y = 80 ÷ 2

y = 40°

The volume of a rectangular prism is (x^3 – 3x^2 + 5x – 3), and the area of its base is (x^2 – 2). If the volume of a rectangula

bixtya [17]

Answer:

The height of the prism is equal to $h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)$

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

$V=Bh$

where

B is the area of the base of the prism

h is the height of the prism

In this problem we have

$V=x^{3}-3x^{2}+5x-3$

$B=x^{2}-2$

substitute in the formula and solve for h

$x^{3}-3x^{2}+5x-3=(x^{2}-2)h$

$h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)$

Determine whether or not the following question can be considered as a statistical question.

aleksandr82 [10.1K]

Answer:. No

Step-by-step explanation:

Explanation:

The answer is NO because, mostly, there is always a variability in

the data used in answering statisticall questions. As in the question above, no variability

because Megan is taller than Jim or she is not taller than jim.

Thus, the question is not statistical in nature.

The bed of a truck is stacked with with boxes of paper. The boxes are stacked 5 boxes deep by 4 boxes high by 4 boxes across

marysya [2.9K]

Answer:

Step-by-step explanation:

The boxes are stacked 5 boxes deep by 4 boxes high by 4 boxes across, then there are $5\cdot 4\cdot 4=80$ boxes in total.

The mass of 1 box of paper is 22.5 kilograms, so 80 boxes weigh $22.5\cdot 80=1800$ kilograms.

When the driver is in the truck, the mass is 2948.35 kilograms, then the total mass is

$2948.35+1800=4748.35\ kg.$

Let n be the number of boxes of paper the driver must deliver at the first stop. Their weigth is 22.5n kg and the weight of the truck without n boxes is

$4748.35-22.5n\ kg.$

Trucks with a mass greater than 4700 kilograms are not allowed over the bridge, thus

$4748.35-22.5n48.35,\\ \\n>\dfrac{967}{450}=2\dfrac{67}{450}.$

Hence, the driver must deliver at least 3 boxes at the first shop.
