Answer 1

Answer:

20

Step-by-step explanation:

115+x = 135 (remote interior angles)

x = 135-115

x = 20

Please Make Me Brainlist

Answer 2

Answer:

20

Step-by-step explanation:

first look at the line which says a and 135, they add up to 180 so

a + 135 =180

a= 180-135

a= 45

Then to find the x we will have to add all the angles inside the triangle which would add up to 180

So,

x+115+45=180

x+160=180

x=180-160

x=20

THEREFORE X = 20⁰

A farmer is constructing a second rectangular greenhouse similar to another greenhouse using a scale factor of 2. The first greenhouse has a width of 10 meters, and a length of 20 meters. What is the perimeter of the second greenhouse.

Answers

Answer: 120 meters

Step-by-step explanation:

The first greenhouse has a width of 10 meters, and a length of 20 meters. Since a scale factor of 2 is used, we have to multiply the length and width by 2.

Length of second greenhouse = 20 × 2 = 40

Width of second greenhouse = 10 × 2 = 20

The perimeter of the second greenhouse will then be:

= 2(length + width)

= 2(40 + 20)

= 2 × 60

= 120 meters

If Rodney traded €228.75 for $314.52, when did he make his exchange?
a. Saturday
b. Friday
c. Thursday
d. Tuesday

Answers

The answer is C Thursday

If Rodney traded €228.75 for $314.52 then his exchange was done on Friday, Option B is correct.

Rodney received $314.52 for €228.75, then the exchange rate he received is:

Exchange rate = dollars per euro = $314.52 / €228.75

= 1.3748

Let us compare this exchange rate with the rates given in the table to find the corresponding day:

Monday: 1/0.7102 = 1.4072

Tuesday: 1/0.7053 = 1.4165

Wednesday: 1/0.6869 = 1.4553

Thursday: 1/0.6910 = 1.4465

Friday: 1/0.7273 = 1.3766

Saturday: 1/0.7544 = 1.3253

The exchange rate received by Rodney  matches the rate on Friday

Therefore, if Rodney traded €228.75 for $314.52 then his exchange was done on Friday

Water and orange squash is mixed in the ratio 11 : 2 Find how much water is needed to dilute 240 cl of orange squash

Answers

Answer: 1,320 cl

Step-by-step explanation:

Water and orange squash are mixed in the ratio 11 : 2.

This means that at their simplest if using cl, it would take 11cl of water and 2 cl of orange squash for a proper dilution.

If 240 cl of orange sqaush is used and you need to find the amount of water, use direct proportion with x as water.

11     :    2

x     :     240

Cross-multiply:

2x = 11 * 240

x = 2,640 / 2

= 1,320 cl

A product is composed of four parts. In order for the product to function properly in a given situation, each of the parts must function. Two of the parts have a 0.79 probability of functioning, and two have a probability of 0.83. What is the overall probability that the product will function properly?

Answers

Answer:

0.430

Step-by-step explanation:

Product has four parts :

For proper functioning, each part must function :

Let the 4 parts be:

A, B, C and D

Proper functioning probability :

A and B = 0.79

C and D = 0.83

For proper functioning :

P(A) * P(B) * P(C) * P(D)

0.79 * 0.79 * 0.83 * 0.83

= 0.42994249

= 0.430
