4. Point V is somewhere on UW. If UV - 2x - 13, VW--18+ 2x, and UW = 17, then find the length of UV.

Slav-nsk [51]

The length of UV is 11.

Solution:

UV = 2x - 13

VW = -18 + 2x

UW = 17

UV + VW = UW

2x - 13 - 18 + 2x = 17

4x - 31 = 17

Add 31 on both sides.

4x - 31 + 31 = 17 + 31

4x = 48

Divide by 4 on both sides.

$$\frac{4x}{4} =\frac{48}{4}$

x = 12

UV = 2x - 13

= 2(12) - 13

= 24 - 13

UV = 11

The length of UV is 11.

7. What is the cardinality of each of the following sets?

zysi [14]

Answer:

The cardinality of set (a) is 0,

the cardinality of set (b) is 1

and

the cardinality of set (c) is 3.

Step-by-step explanation: We are given to find the cardinality of each of the following sets :

(a) { }.

(b) { { } }.

(c) {a, {a}, {a, {a}} }.

We know that

CARDINALITY of a set is the number of elements present in the set.

(a) The given set is A = { }.

The set A is an empty set, so it does not contain any element. Hence, the cardinality of the set A is 0.

(b) The given set is B = { { } }.

The set is B is singleton set, contains only one element (that is empty set). So, the cardinality of the set B is 1.

(c) The given set is C = {a, {a}, {a, {a}} }.

The set C has three elements, a, the set {a} and the set {a, {a}}. So, the the cardinality of set C is 3.

Thus,

the cardinality of set (a) is 0,

the cardinality of set (b) is 1

and

the cardinality of set (c) is 3.

Which diagram shows plane PQR and plane QRS intersecting only in QR

butalik [34]

Answer:

Correct choice is 3

Step-by-step explanation:

Two intersecting planes intersect in line consisting of all common points of both planes. You cna name this line knowing at least two common points of these two lines.

1 picture shows that planes PQS and PRS intersect in PS (common points are P and S).

2 picture shows that planes PRS and PQR intersect in PR (common points are P and R).

3 picture shows that planes PQR and QRS intersect in QR (common points are Q and R).

4 picture shows that planes PQR and PQS intersect in QP (common points are P and Q).

Can someone help me with this

Delicious77 [7]

The definition of a triangle is a polynomial with 3 sides and interior angles adding up to 180.

Using the definition, we can create an equation.

$180=42+31+x$

$180=73+x$

$x=107$

The measure of the third interior angle is 107 degrees.

Hope this helps.

頑張って!
