ΔAXY ~ ΔABC. What is the value of BC

Answers

Answer:

BC = 28 [tex]\frac{1}{3}[/tex] ft

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AX}{AB}[/tex] = [tex]\frac{XY}{BC}[/tex] , substitute values

[tex]\frac{12}{20}[/tex] = [tex]\frac{17}{BC}[/tex] ( cross- multiply )

12BC = 340 ( divide both sides by 12 )

BC = [tex]\frac{340}{12}[/tex] = [tex]\frac{85}{3}[/tex] = 28 [tex]\frac{1}{3}[/tex]

The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 140 centimeters in 35 seconds. What is the time in seconds the toy robot moves when the total distance is 70 centimeters?

Answers

Answer:

17.5 seconds

Step-by-step explanation:

140 cm/35 sec (find unit rate)

4 cm/ 1 second

[tex]\frac{4}{1} = \frac{70}{x}[/tex] (divide 70 by 4)

70/4=17.5

[tex]\frac{4}{1} = \frac{70}{17.5}[/tex]

D Melissa takes the 10 30 from Christchurch. How long does she wait in Wellington? Hour minutes

Answers

Answer:

1:45 hours

Step-by-step explanation:

Given

See attachment for missing part of the question

Required

How long she waits in Wellington

From the question:

She takes the 10 30 from Christchurch

So:

[tex]Christchurch\ Depart = 10\ 30[/tex]

This implies that:

She has to wait until Wellington arrives at 11 15

So:

[tex]Wellington\ Arrives= 11\ 15[/tex]

So, the wait time is:

[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]

[tex]Wait\ time = 11: 15 - 10: 30[/tex]

[tex]Wait\ time = 1:45\ hr[/tex]

A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?

Answers

Answer: [tex]35,000\ cm^3[/tex]

Step-by-step explanation:

Given

The earring box has a volume of [tex]a=5\ cm[/tex]

It is packed and loaded in the container which has 4 layers and each layer has  7 rows and 10 columns

We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]

The volume of each earring box is

[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]

Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]

the container can hold 280 boxes

[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]

Answers

D. 17 inches
To be a triangle, any two sides have to add to be larger than the remaining side. An isosceles triangle has two sides that are the exact same length, which eliminates options B and C. 8 + 8 = 16, which is less than 17, so option A is out, leaving only option D.


What does the discriminant determine?

Answers

It determines if the solution is equal, less than , or more than zero so if it’s equal you only have one solution but if it’s less than so it’s an imaginary graph that doesn’t have solution or more than means it has more than a solution

Answers

The correct question is:

[tex]\angle QPS=88[/tex]  

[tex]\angle RPS=5x+34[/tex]

[tex]\angle QPR=8x+15[/tex].

Find ∠QPR.

Answer:

[tex]\angle QPR = 39[/tex]

Step-by-step explanation:

From the attached figure:

[tex]QPS = QPR + RPS[/tex]

This gives:

[tex]88 = 8x + 15 + 5x + 34[/tex]

Collect like terms

[tex]88 - 15 - 34 = 8x + 5x[/tex]

[tex]39 = 13x[/tex]

Divide both sides by 13

[tex]3 = x[/tex]

[tex]x =3[/tex]

Substitute [tex]x =3[/tex] in [tex]\angle QPR=8x+15[/tex]  

[tex]\angle QPR = 8 * 3 + 15[/tex]

[tex]\angle QPR = 24 + 15[/tex]

[tex]\angle QPR = 39[/tex]
