Please help me with this please and thank you please actually help me

Since a= 10, we know that b = 4a - 5

 --> b = 4(10) - 5 = 40 - 5 = 35

By looking at the table at the left, the value of of c that goes with a when a = 10 is

--> 19.

So b = 35 and c = 19.

Hope that helps!

Answer:

e = -4

step-by-step explanation:

2e + 3 + 7 = 2

2e + 10 = 2

2e = 2 - 10

2e = -8

e = -8/2

e = -4

verification:

2e + 3 + 7

2(-4) + 3 + 7

-8 + 10

2 ... Therefore proved.

Answer:

e = -4

Step-by-step explanation:

2e + 3 + 7 = 2

2e + 7 = -1

2e = -8

e = -4

First I subtracted the 3 off both sides to keep the equation equal getting me -1. Then i subtracted off the 7 from both sides getting me -8. Finally, i divide both sides by 2 and get -4. E will equal -4.

Have an amazing day!!!

carrect answer is : multiply 40x20

Answer:

D. Multiply 40 x 8

Step-by-step explanation:

Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

Speed is the ratio of total distance travelled to total time taken. It is given by:

Speed = distance / time

Let a represent Karen speed and b represent Melinda speed, hence:

a = b + 10

a - b = 10   (1)

Also:

a = d₁ / 1

d₁ = a

b = d₂/ 1 hour

d₂ = b

Since they are 108 miles apart, using Pythagoras:

108² = d₁² + d₂²

a² + b² = 11664

(b + 10)² + b² = 11664

b = 71.2 mph, a = 81.2 mph

Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

Basically you'd need the 3cm and the 5cm exact measurements so use a ruler, make sure that the right angle is 90° so use a protractor. It doesnt matter how big side M is you just need to make sure that the 5cm, 3cm and 90° angle are exact

Answer:

19.25 inches

Step-by-step explanation:

x^2 + 5^2 = 8^2= 64

25+ x^2 = 64

x^2 = 64-25= 39

x = 6.24

perimeter = 19.24

[tex] \\ [/tex]

[tex] \\ [/tex]

[tex] \\ [/tex]

[tex] \\ [/tex]

[tex] \\ [/tex]

So to find perimeter of triangle first we have to find value of x.

[tex] \\ [/tex]

As it's Given one angle is 90°

So we can find value of x by using this formula:-

[tex] \\ [/tex]

Hypotenuse ² = Base² + perpendicular ²

[tex] \\ [/tex]

Where :-

Hypotenuse is AC

Base is BC

Perpendicular is AB

[tex] \\ [/tex]

So:-

[tex] \\ [/tex]

⇢AC² = BC² + AB²

[tex] \\ [/tex]

⇢8² = 5² + x²

[tex] \\ [/tex]

⇢64 = 5² + x²

[tex] \\ [/tex]

⇢64 = 25 + x²

[tex] \\ [/tex]

⇢25 + x² = 64

[tex] \\ [/tex]

⇢x² = 64 - 25

[tex] \\ [/tex]

⇢x² = 39 in.

[tex] \\ [/tex]

⇢x = √(39)

[tex] \\ [/tex]

⇢x = 6.2

[tex] \\ [/tex]

Now Let's find perimeter of triangle.

We know :-

Perimeter of triangle = Side one + side two + side 3

[tex] \\ [/tex]

So:-

[tex] \\ [/tex]

⇢Perimeter of triangle = AB + BC + AC

[tex] \\ [/tex]

⇢Perimeter of triangle = 5 + 8 + 6.2

[tex] \\ [/tex]

⇢Perimeter of triangle = 13 + 6.2

[tex] \\ [/tex]

⇢Perimeter of triangle = 19.2 in.

Answer:

0.2588

Step-by-step explanation:

The value of sin pi/12 is equal to the y-coordinate (0.2588). ∴ sin pi/12 = 0.2588.

Let's take No. of large windchime be x

then no. of small windchime be 2x

now, time taken to make one large windchime is 40min and time taken to make one small windchime is 30min.

Total time is 5 hours = 300 min

so time taken to make all large chimes= 40x

time taken to make small chimes = 30*2x= 60x

total time = 300 min

40x + 60x = 300

100x = 300

x = 300/100

x = 3

total small windchimes = 2x = 2*3=6

total large windchimes = x = 3.

so I hope it's helpful. It really took some time

Answer:

C) 5/8

Step-by-step explanation:

By calculation:

We need to find 3/4 of 5/6.  To do this, simply multiply and simplify:

[tex]\dfrac34 \times \dfrac56=\dfrac{3 \times 5}{4 \times 6}=\dfrac{15}{24}=\dfrac58[/tex]

By using the model:

Total number of squares = 6 × 4 = 24

Total number of blue squares = 5 × 3 = 15

Therefore, the fraction of blue square is [tex]\dfrac{15}{24}[/tex]

We can simplify this fraction by dividing both the numerator and denominator by 3:

[tex]\dfrac{15 \div 3}{24 \div 3}=\dfrac58[/tex]

Step-by-step explanation:

If the ratios of the 3 pairs of corresponding sides of the 2 triangles are equal , then the triangles are similar (SSS postulate )

the3 ratios of the 2 triangles , left to right are all equal to

[tex]\frac{3}{4}[/tex]

Then the triangles are similar by the SSS postulate

the corresponding angles of similar triangles are congruent, then

∠ c = 60°

Also both triangles have 3 congruent sides and are therefore equilateral triangles with all angles equal to 60°, so

c = 60°

Given, Sylvie needs $110 for a concert ticket.

Sylvie has $16.

Her hourly earnings = $h

Sylvie is working 10 hours at her job.

She is getting in 1 hour = $h

So, 10 hours she will get = $ = $

So the total amount she has now = $16 + $(10h) = $()

So we can write the equation as,

110=16+10h

We can move 16 to the left side also. 16 is added to the right side. We can move it by using reverse operation of addition. Reverse operation of addition is subtraction. So we will subtract 16 from both sides. Subtracting 16 we will get,

110-16=16+10h-16

110-16=10h

We have got the required answer.

To find Sylvie's hourly income the correct options are option A and option D.

Sylvie needs 110

She Already Have 16

10 Per Hour

110 ÷ 10 = 11

She Will Got 110 If she Work 11 hours
