Answers

Answer 1

Answer:

The answer is D.

Step-by-step explanation:

First, you have to find the differences in number of guests in this 2 party :

[tex]31 - 20 = 11 \: guests[/tex]

Next, you have to divide by the smaller value which is the first party, then, multiply by 100 as the question wants percentage increase :

[tex] \frac{11}{20} \times 100 = 55\%[/tex]

ANSWER THIS FOR 11 POINTS, what are the slope and y intercept of the function?

Answers

Answer:

y intercept=4 and the slop is 1/3

Step-by-step explanation:

The y intercept is the point where the line intersects the y axis. As we can see the line is intecepting the y axis at point 0,4 or just 4. To find the slope from that point you need to go y places up or down and x places left or right-additionally the point has to be on that line. For example from point 0,4 which is our y-intercept if we go up 1 and over 3 to the right from that point then we get another point that's on the line.

w=4u + 3
Find the value of w when u=8

Answers

Answer:

35 You need to put 8 as w=4(8)+3 then you times 4 and 8 which equals 32 then you are going to add 32 with 3 to get 35

The value of W is 35 if we put u = 8 in the equation W = 4u + 3.

What is an equation?

An equation is a mathematical statement in algebra that consists of an equal symbol between two algebraic expressions with the same value.

How to solve this problem?

Given that W = 4u + 3.

In order to get the desired value, we have to put u = 8 in this equation.

Then W = 4 × 8 + 3 = 32 + 3 = 35

Therefore, the value of W is 35 if we put u = 8 in the equation W = 4u + 3.

Vance wants to determine if an old photo frame is still rectangular. The height of the frame is
8 inches, the base is 6 inches and the diagonal is 10 inches long. Is the old photo frame still
rectangular? How do you know?

Answers

Answer:

The old photo frame is still rectangular

Step-by-step explanation:

Rectangles

The rectangle shape can be identified because it has 4 internal angles of 90° each. The diagonal forms with two adjacent sides a right triangle where the Pythagora's Theorem must stand. Being a and b the length of the sides of the rectangle and d the diagonal, then:

[tex]d^2=a^2+b^2[/tex]

Vince's photo frame has dimensions of 8 inches and 6 inches, with a diagonal of 10 inches. If the above condition is met, then the frame is still rectangular.

Calculating:

[tex]10^2=6^2+8^2[/tex]

[tex]100=36+64[/tex]

[tex]100=100[/tex]

Since the condition is met, the old photo frame is still rectangular
