(II) 2 s.f ( two significant figure)
(III) 3 s.f (three significant figure).

(a). 0.004816
(b). 50.00168
(c). 0.0009812​

Answers

Answer 1

Answer:

(a)

1 sig: 0.005

2 sig: 0.0048

3 sig: 0.00482

(b)

1 sig: 50

2 sig: 50.

3 sig: 50.0

(c)

1 sig: 0.0010

2 sig: 0.00098

Step-by-step explanation:

Significant Figures Rules:

Any non-zero digit is significant.Any trailing zeros after the decimal is significant.Any zeros between 2 significant digits are significant.Zeroes before significant numbers in the decimal place are NOT significant; they are placeholders.

(a)

0.004816 - the zeros are placeholders, so they do not count as sig figs.

(b)

50.00168 - the zeros are between 2 significant figures, so they do count as sig figs.

(c)

0.0009812 - the zeros are placeholders, so they do not count as sig figs

12 = 7 - 3x + 5x​

Answers

Answer: 12=7−3x+5x

Step 1: Simplify both sides of the equation.

12=7−3x+5x

12=7+−3x+5x

12=(−3x+5x)+(7)(Combine Like Terms)

12=2x+7

12=2x+7

Step 2: Flip the equation.

2x+7=12

Step 3: Subtract 7 from both sides.

2x+7−7=12−7

Answers

Answer:

YZ = 25.40 correct to 1dp

Step-by-Step explanation:

Sin16°= XZ/YZ

YZ=XZ/sin16°

YZ=7/0.276

YZ=25.3623188405797

YZ = 25.40 correct to 1dp

Answer:

XZ ≈ 24.39

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan16° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{YZ}[/tex] = [tex]\frac{7}{YZ}[/tex] ( multiply both sides by YZ )

YZ × tan16° = 7

YZ × 0.287 = 7 ( divide both sides by 0.287 )

YZ = [tex]\frac{7}{0.287}[/tex] ≈ 24.39 ( to 2 dec. places )

Answers

Answer:

64

Step-by-step explanation:

Let x represent the number.

x + 23 represents 23 added to the number.

2x - 41 represents 41 less than twice the number.

Set these expressions equal to each other and solve for x to find the number:

x + 23 = 2x - 41

23 = x - 41

64 = x

So, the number is 64

Answers

Answer:

The answer is $43623.50

Step-by-step explanation:

This problem is on compound interest.

the expression for compound interest is given as

A=P(1+r)^t

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Given data

P= $2,500

r= 10/100= 0.1

t= 30 years

substituting into the expression for compound interest and solving for A we have

A=2500(1+0.1)^30

A=2500(1.1)^30

A=2500*17.449

A=$43623.50

The final amount is $43623.50

Her account balance is a result of Jenna’s(A annuity payments)

Answer:

Step-by-step explanation:

Solve for n -3n-5=16

Answers

Answer:

n = -7

Step-by-step explanation:

Solve for n:

-3 n - 5 = 16

Hint: | Isolate terms with n to the left-hand side.

Add 5 to both sides:

(5 - 5) - 3 n = 5 + 16

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

-3 n = 16 + 5

Hint: | Evaluate 16 + 5.

16 + 5 = 21:

-3 n = 21

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 21 by -3:

(-3 n)/(-3) = 21/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 21/(-3)

Hint: | Reduce 21/(-3) to lowest terms. Start by finding the GCD of 21 and -3.

The gcd of 21 and -3 is 3, so 21/(-3) = (3×7)/(3 (-1)) = 3/3×7/(-1) = 7/(-1):

n = 7/(-1)

Hint: | Simplify the sign of 7/(-1).

Multiply numerator and denominator of 7/(-1) by -1:

Answer: n = -7

Answer:

n = -7

Step-by-step explanation:

Add 5 to each side, so it now looks like this: -3n = 21Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = -7

Answers

Answer:B have it ✅

Step-by-step explanation:

The value of x for the given equilateral triangle is 28.

What is an equilateral triangle?

A triangle having all sides equal and each angle measures 60° is called

an equilateral triangle.

Given that, the measure of each angle in an equilateral triangle is represented by the expression 2x + 4.

We know that each angle in an equilateral triangle measures 60°

Therefore, 2x+4= 60

2x = 56

x = 28

Hence, the value of x is 28.

Answer:

Boys : 104

We know:

For every 8 boys there is 5 girls so the ratio is:

8 : 5

There are 169 total students

We are going to take these students as cookies and how many of them we are going to bake in batches

Step-by-step explanation:

Add 8 and 5 together to find out how many students in each 'Batch' 8 + 5 = 13

Then divide 169 by 13 which equals 13. Now you know how many 'Batches' there are.

To find the answer Multiply 13 by 8 and 5 ;

13 * 8 = 104

13 * 5 = 65

Check the answer:

104 + 65 = 169

Solve for a. Show (All steps must be shown): -2(a-3)=12

Answers

Answer:

a= -3

Step-by-step explanation:

first distrubute the parenthesis -2(a-3)

-2a+ 6= 12

then move the like terms

6 becomes -6 and subtract to both sides so 6-6 cancels out and you are left with 12-6 which gives you 6

then you have -2a = 6

lastly divide on both sides and you get

-2a÷ -2 (cancels out)

6÷ -2

and the answer is

a= -3
