Annika is 8 years older than Rohan. Three years ago, Annika was 3 times older than Rohan was then. How old is Annika and Rohan now?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.

To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Answer: 2.5 feet

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle in which the sides all have a fixed relationship with each other.  We only need to know one side to calculate the other two.

Make the side opposite the 30° angle x, then

The side opposite the right angle is 5ft, therefore:

2x = 5

x = 2.5ft, the side opposite the 30° angle

Then x*√3 is the third side:

(2.5)*(1.442) = 3.605 feet

10%

Step-by-step explanation:

($3.95 - $3.45)/($3.95) × 100%

= ($0.50)/($3.95) × 100%

= 50/3.95 %

= 5000/395 %

= 1000/79 %

= 12,65 % → Round to the nearest tenth

≈ 10 %

Answer:

12 sandwiches

Step-by-step explanation:

We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:

24 / 2 = 12

Therefore, Deion can make 12 sandwiches before he runs out of cheese.

Hope this helps :)

Answer: 7

Step-by-step explanation:

Write as a decimal

7 1/2 would be written as ~7.0833

Rounding a decimal to the nearest whole number

If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.

If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.

Since 0 is in the tenth’s place we round down to 7.

Answer:

the equation for the slope inception from

y=[tex]\frac{6}{5}[/tex][tex]x^{2}[/tex] + [tex]\frac{11}{5}[/tex]x + 34

Step-by-step explanation:

Find the slope of the parallel line

(7, 2) and is parallel to y= -2x+1?

When two lines are parallel, they have the same slope.  

                ⇒  if the slope of the given line is = - 2      

                     then the slope of the parallel line (m) = - 2

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                              ⇒  y - 2  =  - 2 (x - 7)                                  

We can therefore write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:  

                     since   y - 2  = - 2 (x - 7)  

Step-by-step explanation:

Given,

John get paid for working per hour = £6.80

he worked this week = 9 1/2 hr can be written as 19/2 hr.

so, total amount he will get paid for working 19/2 hr

= 19/2 × 6.80

= 19 × 3.40 = 64.60 or 64.6

therefore, John's total.pay of this week is £64.6.

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

If there are 324 paving stones, it will cost $1539

Step-by-step explanation:

324 x 4.75 = 1539

The probability that this person does not make use of the facility is 7/130

61+68+60 - 25-28-19 + 6

= 123

The total number of person in the sport center is given as 130

We have 130 - 123 = 7

This means that there are a total of 7 persons that do not make use of this facility.

Hence the probability of a person not using the facility is 7/130

Answer:-105

Step-by-step explanation:

Answer:

Ok so, let's break it down

Step-by-step explanation:

-35+(-31)

Let's ignore the parenthesis and the - symbol

35+31

That would equal 66, so now we add back the - symbol which will make it -66

So we already have -66, so now we have -66+(-39)

We do the same thing we did with -35+(-31)

So we have 66+39

That makes -105

So your answer is -105

Answer:

x = 44

y = 136

z = 136

Step-by-step explanation:

The angles of a triangle have to add up to 180°

54 + 82 + x = 180

136 + x = 180

x = 44

We know that y and z are vertical angles, so they have the same measurements.

Also, x and the other angle across from it are also vertical angles.

88 + 2n = 360

2n = 272

n = 136

Therefore,

x = 44

y = 136

z = 136

Step-by-step explanation:

anything whole or complete is designated as 100%.

what is x% of that whole ?

well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.

100×f = x

f = x/100

whole × f = x% of the whole

so, when we are looking for 5%, what did that mean ?

it means that x = 5, and f = 5/100.

therefore, 5% of $13 is

13 × 5/100 = 65/100 = 0.65

so,

basic cost = $13

tax rate = 5%

tax amount = $0.65

and

basic cost = $13

tax amount = $0.65

total cost = 13 + 0.65 = $13.65

as 5/100 = 0.05

we have seen that the tax amount is simply $13×0.05

and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total

total cost = $13×(1+0.05) = $13×1.05 = $13.65

so, the decimal factor we can use directly without going through all the detail above is : 1.05
