A P E X

Given:

In triangle UVW, X is the midpoint of UV and Y is the midpoint of VW.

[tex]m\angle XYV=7x+21[/tex]

[tex]m\angle UWY=91-7x[/tex]

To find:

The measure of angle XYV.

Solution:

Since X is the midpoint of UV and Y is the midpoint of VW, therefore XY is the mid-segment of the triangle UVW and parallel to the base of the triangle, i.e., UW.

If a transversal line intersect two parallel lines, then the corresponding angles are congruent and their measures are equal.

[tex]\angle XYV \cong \angle UWY[/tex]         [Corresponding angle]

[tex]m\angle XYV=m\angle UWY[/tex]

[tex]7x+21=91-7x[/tex]

We need to solve this equation for x.

[tex]7x+7x=91-21[/tex]

[tex]14x=70[/tex]

[tex]x=\dfrac{70}{14}[/tex]

[tex]x=5[/tex]

Now,

[tex]m\angle XYV=7x+21[/tex]

[tex]m\angle XYV=7(5)+21[/tex]

[tex]m\angle XYV=35+21[/tex]

[tex]m\angle XYV=56[/tex]

Therefore, the measure of angle XYV is 56 degrees.

Answer:

Arc length of the semicircle is 12.57 cm.

Step-by-step explanation:

From the given picture,

Measure of diameter = 8 units

Radius of the semicircle = [tex]\frac{\text{Diameter}}{2}[/tex]

                                        = [tex]\frac{8}{2}[/tex]

                                        = 4 units

Since, circumference of a semicircle is given by the expression,

C = πr

Here, r = radius of the semicircle

Circumference of the given semicircle = π(4)

                                                                = 4π

                                                                = 12.57 cm

Therefore, arc length of the semicircle is 12.57 cm.

Answer:

40 books

Step-by-step explanation:

Divide 20 kg by 500 g, or, alternatively, divide 20 kg by 0.5 kg.

Either way, the result is 20/0.5, or 40.

40 books of the same mass would have the same mass as the bookcase.

Hope this helps :)

Answer: 98

Step-by-step explanation:

First find the mean of the numbers you currently have.

93 + 95 + 89 + 95 + 100

and divide by 5 to get 94.4.

Now you need to find the extra number.

The number has to be higher than 94. I know there is an easier way, but I started by adding 100 and kept going down til I was at 98.

93 + 95 + 89 + 95 + 100 + 98

divided by 6 is 95

Answer:

5/8 ft²

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Base = 5/3 ft

Height = 3/4 ft

Area of a triangle = 1/2 * base * height

= 1/2 * 5/3 ft * 3/4 ft

Multiply numerator separately and denominator separately

= (1 * 5 * 3) / (2 * 3 * 4) ft²

= 15/24 ft²

= 5/8 ft²

Area of a triangle = 5/8 ft²

Answer

Equation: m - 12 = 20

Answer:

0 cm³

Step-by-step explanation:

the lost of water =

(5×24)/12 x 1/10 × 18000

= 10/10 × 18000 = 18,000 cm³

so, the remaining water in the tub=

18,000 - 18,000 = 0 cm³

(the tub is empty)

Answer:

Probability of choosing green and yellow treat  is higher than Probability of choosing an orange and yellow treat  by 0.08

Step-by-step explanation:

Given -

Green and yellow gummy treats = 20

Red and yellow gummy treats = 14

Orange and yellow gummy treats = 16

Total gummy treat = 20+14+16 = 50

Probability of choosing green and yellow treat = 20/50 = 0.4

Probability of choosing an orange and yellow treat = 16/50 = 0.32

Probability of choosing green and yellow treat  is higher than Probability of choosing an orange and yellow treat  by 0.08

Answer:

provides information about the strength of a relationship

Step-by-step explanation:

A numerical measure of strength in the linear relationship between any two variables is called the Pearson's product moment correlation coefficient.

The co efficient of correlation is a pure number denoted by r , independent of the units in which the variables are measured that can range from+1 to -1 .

The sign of r indicates the direction of the cor relation.

When r= 0 it does not mean that there is no relationship . For example if the observed values lie exactly on a circle , there is a relationship between variables but r = 0  as r only measure linear cor relation.

The 2nd statement given is the correct answer.

It is not related to ordinal or nominal properties and it does show direction.

Answer:

Tyler should make 8 a day. You do 122-66 which is 56 and there are 7 days in a week so 56 divide by 7 is 8.

Tyler has to make 8 invitations each day.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Total number of invitations to the fair = 122

Already, 66 invitations has been made.

Remaining invitations = 122 - 66 = 56

56 invitations has to be made in a week or 7 days.

Let x be the number of invitations made each week.

x = 56 / 7 = 8

Hence 8 invitations has to be made each day.

Answer:

120° or 300°

Step-by-step explanation:

Given,

Slope (m) = -√3

Inclination (α) = ?

Now,

We know,

m = tanα

or, -√3 = tanα

or, tan(120° or 300°)  = tanα

∴ α = 120° or 300°

∴ Inclination is 120° or 300°
