Which shape has 5 faces, 8 edges and 5 vertices? A. triangular pyramid B. rectangular pyramid C. rectangular prism D. triangular prism

Answers

Answer:

Rectangular Pyramid

Step-by-step explanation:

Rectangular Pyramid-It has 5 faces, 8 edges and 5 vertices.

Answer:

C. Rectangular Pyramid

Step-by-step explanation:

Faces:

A rectangular pyramid has a rectangle as its base. So from it's pinnacle to each of the rectangle's edges, there is a triangular face. As the base has 4 sides, it should have 4 such faces. And the base rectangle is also a face. So it has a total of 5 faces.

So, the number of faces [tex]$F$[/tex] = 5

Edges:

And from its pinnacle to 4 base vertice there are 4 edges. And the base rectangle has four edges. So there are a total of 8 edges

So, the number of edges [tex]$E$[/tex] = 5

Vertice:

The number of vertices [tex]$V$[/tex] must be 5. Becaue we know by Euler's formula [tex]$V + F - E = 2$[/tex] which holds for any shape that doesn't have any hole within it. And 5 is the only value for [tex]$V$[/tex] that satisfies the equation.

So we can conclude that, the shape must have to be rectangular pyramid.

If a 20-foot tree casts a shadow of 15 ft how long is the shadow of a student who is 5 ft 4 in tall?​

Answers

Answer:

4 feets

Step-by-step explanation:

Given that :

Height of tree = 20 feets

Shadow of tree = 15 ft

Height of student = 5ft 4 in ; 4 in = 0.3333 foot = 5.3333 feet

Shadow of student = s

Height of tree / shadow of tree = height of student / shadow of student

20 / 15 = 5.33333 / s

Cross multiply :

20 * s = 15 * 5.33333

s = 79.99995 / 20

s = 3.9999975

Shadow of student =, 4 feets

What is the value of x? Answer must be in decimal form 1.5x + 4 = 2.3x - 1.2
I need help

Answers

Answer:

x = 6.5

Step-by-step explanation:

1.5x - 2.3x + 4 = 1.2

1.5x - 2.3x = -1.2 - 4

-0.8x = - 1.2 - 4

-0.8x = -5.2

divide both sides of the equation by -0.8

x = 6.5   :)

Find the perimeter. The shape consists of a square and a half circle. Solve​

Answers

Answer and Step-by-step explanation:

We have 3 sides of a square on the outside, so 2 + 2 + 2 equals 6. This is part of the perimeter.

Now we find the circumference of half the circle.

Radius of 1, So the circumference for half of this circle is pi, or 3.14.

So, the answer is 3.14 + 6, which equals 9.14.

The perimeter of the shape is 9.14.

Answers

Given:

The equation is

[tex]\dfrac{2}{5}x+9=9[/tex]

To find:

The statement for the given equation.

Solution:

For "more" or "plus" we use "+" sign.

For "of" we use "×" sign.

Let x be the unknown number.

Two-fifths of nine is a number.

[tex]\dfrac{2}{5}(9)=x[/tex]

Two-fifths of a number is nine.

[tex]\dfrac{2}{5}x=9[/tex]

A number plus nine is the same as two-fifths of nine.

[tex]x+9=\dfrac{2}{5}(9)[/tex]

These equation are different from the given equation. So, the options A, B and D are incorrect.

Nine more than two-fifths of a number is nine.

[tex]\dfrac{2}{5}x+9=9[/tex]

It is same as the given equation. Therefore, the correct option is C.

The US Department of Education concluded that this disparity is not explained by more frequent or more serious misbehavior by students of color.[1]In New York City, 88% of police stops in 2018 involved Black and Latinx people, while 10% involved white people. (Of those stops, 70% were completely innocent.)[2]In one US survey, 15.8% of students reported experiencing race-based bullying or harassment. Research has found significant associations between racial bullying and negative mental and physical health in students.[3]From 2013 to 2017, white patients in the US received better quality health care than about 34% of Hispanic patients, 40% of Black patients, and 40% of Native American patients.[4]Black women are 3 to 4 times more likely to experience a pregnancy-related death than white women, even at similar levels of income and education.[5]Black Americans are more likely than white Americans to be arrested.

Once employed, Black individuals earn nearly 25% less than their white counterparts.[9]One US study found that job resumes with traditionally white-sounding names received 50% more callbacks than those with traditionally Black names.[10]In the US, Black workers are less likely than white workers to be employed in a job that is consistent with their level of education.[11] describe how the particles in the pot transfer energy Can you please help me.
