a)14x 10∧-14times b) 4 x 10 ∧-14timesc) 14x 10∧-11times d) 4 x 10∧6times

Answers

Answer 1

Answer:

D. 4 × 10⁶ times

Step-by-step explanation:

The diameter of a pearl is

4 × 10⁻³cm = 4 × 10⁻⁵ m

The diameter of an atom is

10⁻¹¹m

How much larger than an atom is a pearl?

4 × 10⁻⁵ ÷ 10⁻¹¹ = 4 × 10⁻⁵⁺¹¹ = 4 × 10⁶ times

Correct option is D

through: (-3,-5), parallel to y = 2x + 2​

Answers

Answer:

y = 2x + 1

Step-by-step explanation:

Since you have an equation and a point, all you need to do is substitute the coordinates into the equation and then solve for the y-intercept (or "b"):

y = mx + b

y = 2x + 2

(-3, -5)

-5 = 2(-3) + b

-5 = -6 + b

-5 + 6 = b

b = 1

Now you have your final equation:

y = 2x + 1

By what number must be 566 be divided so as to give a quotient 15 and reminder 11?​

Answers

Step-by-step explanation:

566 - 11 = 555

555 / 15 = 37.

The number is 37.

Answer:

[tex]\boxed{\pink{\sf \leadsto The \ required \ number \ is \ 37 . }}[/tex]

Step-by-step explanation:

We need to find the number By what number must be 566 be divided so as to give a quotient 15 and reminder 11.

So , let us take the number be x .

Now , we know that ,

[tex]\boxed{\red{\bf Dividend = Quotient\times Divisor + Remainder }}[/tex]

Here , 566 will be Dividend , 11 is remainder and 15 quotient . x will be the Divisor .

[tex]\implies Dividend = Quotient\times Divisor + Remainder \\\\\implies 566 = 15 \times x + 11 \\\\\implies 566 = 15x + 11 \\\\\implies 15x = 566 - 11 \\\\\implies 15x = 555 \\\\\implies x =\dfrac{555}{15}\\\\\underline{\boxed{\orange{ \tt \implies x = 37}}}[/tex]

Hence the required number is 37 .

lin paid $94 for 6 meals. How much would 9 meals cost?

Answers

Answer:

140.4

Step-by-step explanation:

Answer:

$141.01 and if it is the nearest whole number it would be $141

Step-by-step explanation:

first you have to do 94 divided by 6. you do this to see how much 1 meal cost.

then you get: 15.67

now you take 15.67x3=47.01

cuz we need 3 more meals. we know this cuz we have 6 and want 9 so 6-9 is 3.

now we take 47.01+94=141.01

we just need to add 3 to the 6 we have to make 9 meals.

so your answer would be $141.01

If 2a+4b=5 and a is equal to three times b, what is 3a?

Answers

Answer:

3A = 3(1 1/2) = 4 1/2

Step-by-step explanation:

2A + 4B = 5

A = 3B

2(3B) + 4B = 5 [substitute the A for the 3B]

10B = 5 so B = 1/2 [now plug the info in]

2A + 4(1/2) = 5

2A + 2 = 5 [subtract 2 from both sides of the equation]

2A = 3  [divide by 2 to isolate A]

A = 3/2  [now plug in the answers to check your work]

2(3/2) + 4(1/2) = 5

6/2 + 4/2 = 3 + 2 = 5

Answers

Answer:

4 and 20

Step-by-step explanation:

100 times 5 is 500. If we go backwards 500 ÷ 5 = 100.

100 ÷ 5 = 20. 20 ÷ 5 = 4.

An exponential sequence is a sequence that grows more every time. It would get really big really quickly.

The first and second numbers in this sequence is 4 and 20

Given that,

The third and fourth number in an exponential sequence 100 and 500.

Based on the above information, the calculation is as follows:

The sum of the measures of angles for a triangle is 180°. Find the value of x and then the measures of the 3 angles

Answers

Answer:

The value of x is 50

The measures of the 3 angles are 50°, 100°, 30°

Step-by-step explanation:

Let us solve the question

∵ The sum of the measures of the angles of a triangle is 180°

∵ The measures of the 3 angles of the given Δ are x°, 2x°, (x - 20)°

→ Add them and equate the sum by 180

x° + 2x° + (x - 20)° = 180°

→ Add the like terms

∵ (x + 2x + x) + (-20) = 180

4x - 20 = 180

→ Add 20 to both sides

∵ 4x - 20 + 20 = 180 + 20

4x = 200

→ Divide both sides by 4 to find x

x = 50

The value of x is 50

To find the measures of the 3 angles substitute x by 50 in their expressions

∵ The measure of one angle is x

∴ The measure of the 1st angle is 50°

∵ The measure of the 2nd angle is 2x

∴ The measure of the 2nd angle = 2(50)

∴ The measure of the 2nd angle is 100°

∵ The measure of the 3rd angle is (x - 20)

∴ The measure of the 3rd angle = (50 - 20)

∴ The measure of the 3rd angle is 30°

The measures of the 3 angles are 50°, 100°, 30°

If W + 6 = 3 and v-4 = 2, what is the value of w + v?

Answers

Answer:

w = - 3 and v = - 2

Step-by-step explanation:

Because w + 6 = 3 you would subtract 6 and whatever you do to one side you would do to the other.

w= - 3

Answer:

[tex]w + v = 3[/tex]

Step-by-step explanation:

Solve for w

[tex]w + 6 = 3[/tex]

Move 6 to subtract 3.

[tex]w = 3 - 6 \\ w = - 3[/tex]

Solve for v

[tex]v - 4 = 2[/tex]

Move 4 to add 2

[tex]v = 4 + 2 \\ v = 6[/tex]

Solve for w+v

Substitute w = -3 and v = 6

[tex]w + v = - 3 + 6 \\ w + v = 3[/tex]

At the end of a football season a coach is adding up everyone's scores nathan has scored 11 more than harry harry has scored 10 more then jack. If the total of their scores is 91, how much did harry score

Answers

Answer:

Harry has a score of 30

Step-by-step explanation:

Let us represent their scores as:

Nathan = x

Harry = y

Jack = z

At the end of a football season a coach is adding up everyone's scores

Nathan has scored 11 more than harry

x = y + 11

Harry has scored 10 more then jack.

y = z + 10

z = y - 10

If the total of their scores is 91

x + y+ z = 91

y + 11 + y + y - 10 = 91

3y + 1 = 91

3y = 91 - 1

3y = 90

y = 90/3

y = 30

Since Harry's score is represented as y, Harry has a score of 30
