Find The Length Of AC.a. 10.1 B. 10.0c. 10.9d. 8.86 PLEASE HELPPP ASAP

Answers

Answer 1

Answer:

Option D

Step-by-step explanation:

According to law of cosines =

[tex] {a}^{2} = {b}^{2} + {c}^{2} - 2bc. \cos(A) [/tex]

where 'a' is the uknown side , 'b' & 'c' are the given sides and angleA is the angle opposite to the uknown side i.e. opposite to 'a'.

Using the Law of cosines , we'll find the length of AC .

[tex] {ac}^{2} = {7}^{2} + {13}^{2} - 2 \times 7 \times 13 \times \cos(50) [/tex]

[tex] = > {ac}^{2} = 49 + 169 - 182 \times 0.76[/tex]

[tex] = > {ac}^{2} = 218 - 138.8 = 79.68[/tex]

[tex] = > ac = \sqrt{79.68} = 8.92 = 9(appx)[/tex]

In option D , if we'll round of 8.86 , then its appx 9. So option D is right

5a. ΔGKM ~ ΔSPM by SAS

b. ΔABC is not similar to ΔDEF

6. The missing side is 2[tex]\sqrt{11}[/tex]

Step-by-step explanation:

5a. Yes, the triangles are similar.

<KMG ≅ <PMS (vertically opposite angles)

      ΔGKM ~ ΔSPM by SAS

Ratio: GM:SM OR KM:PM

             3:6    OR  2:4

             1:2     OR  1:2

Ratio: 1:2

b. No, the triangles are not similar

   ΔABC is not similar to ΔDEF

Ratio: AC:DF OR AB:DE

         4:6       OR  2:4.5

         1:1.5      ≠     1:2.25

   Ratio: not similar

6. let the missing side of the triangle be represented by x. Since the triangle is a right angled triangle, then applying the Pythagoras theorem we have;

[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]

[tex]/12/^{2}[/tex] = [tex]x^{2}[/tex] + [tex]/10/^{2}[/tex]

144 = [tex]x^{2}[/tex] + 100

[tex]x^{2}[/tex] = 144 - 100

   = 44

x = [tex]\sqrt{44}[/tex]

  = [tex]\sqrt{4 *11}[/tex]

  = 2[tex]\sqrt{11}[/tex]

x = 2[tex]\sqrt{11}[/tex]

The missing side is 2[tex]\sqrt{11}[/tex].

Answer:

The true statement is h < k ⇒ (3)

Step-by-step explanation:

∵ The equation of the graph is y = [tex]\sqrt{x+h}[/tex] + k

(-h, k) are the coordinates of its vertex point

∵ -h is the x-coordinate of the vertex point

∵ x-coordinate of the vertex point is -3

∴ -h = -3

→ Divide both sides by -1

∴ h = 3

∵ k is the y-coordinate of the vertex point

∵ y-coordinate of the vertex point is 4

k = 4

∵ 3 < 4

→ That means h is smaller than k

h < k

The true statement is h < k

If there are 328 million people and 228 thousand become infected each day, how long will it take for all to be infected?

Answers

Answer:

1438.6 days

Step-by-step explanation:

We are told in the above question that:

228,000 people get infected per day. Hence, how long it would take for 328,000,000 people to be infected is calculated as:

228,000 people = 1 day

328,000,000 people = x days

Cross Multiply

228,000 people × x days = 328,000,000 people × 1 day

x days = 328,000,000 people × 1 day/228,000 people

x days = 1438.5964912 days

Approximately = 1438.6 days

Therefore, it would take 1438.6 days for 328,000,000 people to be infected.

What is JK? please explain/show your work on how you got your answer​

Answers

Answer:

JK = 20 m

Step-by-step explanation:

A line segment that connects two midpoints of the sides of a triangle is called a midsegment.A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.

Point J is midpoint of side HI as HJ = JI

Point K is midpoint of side GI as GK = KI

JK is midsegment as connects the midpoints of the sides

JK = 1/2HG as per property of midsegment

6x - 4 = 10x/26x - 4 = 5x6x - 5x = 4x = 4

JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m

Answer:

[tex]JK=20m[/tex]

Step-by-step explanation:

It is given in the diagram that IJ = JH and IK = KG. Therefore, by the definition of a midpoint, we know that J and K are the midpoints of segments IH and IG respectively. Then, it can be concluded that JK is a midsegment by the definition of a midsegment. The Midsegment Theorem states that a midsegment connecting the midpoints of two sides of a triangle is parallel and half of the length of the third side. Thus, we know that JK is half of HG. Now, we can set up the following equation to solve for x:

[tex]JK = \frac{1}{2}HG\\6x-4=\frac{1}{2}(10x)[/tex]

Solving for x, we get:

[tex]6x-4=\frac{1}{2}(10x)\\6x-4=5x\\x-4=0\\x=4[/tex]

Therefore, [tex]JK = 6x - 4 = 6(4) - 4=24-4=20 m[/tex].

Given that,

A food truck is selling 2 burritos for $5.

Solution,

We need to find the relationship between burritos and dollars.

2 burritos = $5

To find the value of 1 burrito. Divide 5 by 2 as follows :

[tex]1\ \text{burrito}=$\dfrac{5}{2}\\\\1\ \text{burrito}=$2.5[/tex]

Hence, the relation between burritos and dollars is " [tex]1\ \text{burrito}=$2.5[/tex]"

1. W = 50 ft

2. L = 110 m

3. L = 61 m

Step-by-step explanation:

Area of a Rectangle

Given a rectangle of width W and length L, its area is calculated by the formula:

A = W.L

We are given three rectangle-shaped figures and are required to find different measures as explained below.

1. Length L=94 ft, Area = 4,700 square ft

We'll find the width by solving for W:

[tex]\displaystyle W = \frac{A}{L}[/tex]

[tex]\displaystyle W = \frac{4,700}{94}[/tex]

W = 50 ft

2. A=8,250 square m, W=75 m

We'll find the length by solving for L:

[tex]\displaystyle L = \frac{A}{W}[/tex]

[tex]\displaystyle L = \frac{8,250}{75}[/tex]

L = 110 m

3. A=1,586 square m, W=26 m

We'll find the length by solving for L:

[tex]\displaystyle L = \frac{A}{W}[/tex]

[tex]\displaystyle L = \frac{1,586}{26}[/tex]

L = 61 m

DEFINITION of Value Change

Value change is an adjustment made to a stock's price to reflect the number of outstanding stock shares issued and currently held by investors. A value change allows the group of stocks to be equally weighted and, therefore, more easily evaluated. Since the number of shares held by investors changes daily, this number can be updated daily to reflect the changes.
