Answer 1

Answer:

The value of the expression 8 - I2g - 5I is -4 ⇒ D

Step-by-step explanation:

The absolute value always gives a positive value IaI = a and I-aI = a

Let us solve the question

∵ The expression is 8 - I2g - 5I

∵ The value of g is g = -3.5

→ To find the value of the expression substitute g by -3.5

∵ 8 - I2g - 5I = 8 - I2(-3.5) - 5I

∴ 8 - I2g - 5I = 8 - I-7 - 5I

∴ 8 - I2g - 5I = 8 - I-12I

→ By using the rule above

∵ I-12I = 12

∴ 8 - I2g - 5I = 8 - 12

∴ 8 - I2g - 5I = -4

∴ The value of the expression 8 - I2g - 5I is -4

What is the value of the expression below? 5+2(10 + 5)​

Answers

U would do 10+5 first then u would do 5+2 so 15+7 =22
The answer is 22. PEMDAS = Parentheses first, so you add 10 + 5 = 15. Then you add 5+2 = 7, = 22.
Or if you’re multiplying it would be 15 x 7

Find the values of x and y.

Answers

Answer:

x=30° y=5

Step-by-step explanation:

All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.

so

8y=40

y=40/8

y=5

Since it's an equilateral triangle. All angles are equal And each angle has dimensions

=180°/3=60°

The angle of the straight line = 180°

so The obtuse angle of the lower isosceles triangle is 180°-60°=120°

The angles at the base of the isosceles triangle are equal

so 2x° = 180°-120°

2x°=60°

x°=60°/2

x°=30°

Complete the pairs of corresponding parts if △RST ≅ △TXY.



ST =
TY
XY
TX

Answers

Answer:

As

ST is corresponding to XY

Hence, we conclude that:

ST = XY

Step-by-step explanation:

Given

△RST ≅ △TXY

To determine:

ST = ?

As

△RST ≅ △TXY

So the triangles △RST and △TXY are congruent to each other.

We know that congruent triangles have equal corresponding parts.

Please check the attached graph.

From the graph, it is clear that:

RT is corresponding to TY.ST is corresponding to XY.RS is corresponding to TX.

We need to determine ST

as

ST is corresponding to XY

i.e. ST = XY

Hence, we conclude that:

ST = XY

A box of chocolates contains five milk chocolates, five dark chocolates, and five white chocolates. You randomly select and eat three chocolates. The first piece is milk chocolate, the second is dark chocolate, and the third is white chocolate. Is it independent or dependen?

Answers

The first piece is milk chocolate, the second is dark chocolate, and the third is white chocolate independent and the probability is 25/546.

What is probability ?

Probability of something is the occurrence of a certain event out of the total events that can occur.

According to the given question

The total no. of chocolates in the box is

(5 + 5+ 5) = 15 chocolates.

The probability of eating a milk chocolate first a dark chocolate second and a white chocolate third is an independent event because occurrence of next event do not depend upon the previous event.

There are 5 milk chocolates.

So, probability of getting a milk chocolate first is

P(mc) = 5/15

= 1/3

Now the the chocolate can no be replaced because it is eaten

∴ Probability of getting a dark chocolate second is

P(dc) = 5/14                          (as the total no. of chocolate is reduced by 1

                                                                    because it has been eaten)  

And the probability of getting a white chocolate in 3rd attempt is

P(wc) = 5/13

As the first piece is milk chocolate, the second is dark chocolate, and the third is white chocolate is an independent event their probability is

P(mc) ∩ P(dc) ∩ P(wc)

= P(mc) × P(dc) × P(wc)

= (1/3 × 5/14 × 5/13)

= 25/546.

what would the area be if x = 5

Answers

Answer:

The area would be 301 if x=5.

Step-by-step explanation:

Given expression is:

5x²+42x+16

We have to find the area when x=5

So putting x=5 in the given expression.

Area = 5(5)²+42(5)+16

Taking square of 5 and multiplying 42 by 5

Area = 5(25)+210+16

Area = 75+210+16

Adding all the terms

Area = 301

Hence,

The area would be 301 if x=5.

The price of a watch was increased by 20% to £162.
What was the price before the increase?​

Answers

The original price is 135
Step-by-step explanation:
Write equation. Let o be original price, r be rate of increase, P be the increased price. o+ro=P
Substitute values. Original price (o) is unknown, so that will stay as it is; we know that the increased price (P) is 162; we know that the rate of increase (r) is 20%, which in decimal form is 0.20 o+0.20o=162
Add like terms. o is the same as 1o. So 1+0.20 is 1.20. 1.20o=162
Isolate the variable (o). To isolate o, you need to divide both sides by 1.20. 1.20 divided by 1.20 is the same as 1. 162 divided by 1.20 is 135. o=135
Check your work. Plug in the values into the equation and check if it is correct: o+ro=P becomes (135)+(.20)(135)=162. That is simplified into 135+27=162, which is further simplified into 162=162
It’s correct, the answer is 135

Answer:

£129.60

Step-by-step explanation:
