Answer:

Numerator: A + 8

Complete Form: [tex]\frac{A+8}{b}[/tex]

Step-by-step explanation:

Hello!

If we have two fractions that are being added or subtracted with the same denominator, we can simply add up the numerators and keep it over the same denominator.

Let's use this question as an example:

The problem is basically saying, "If I took A slices from b slices and 8 slices from b slices, how many slices would I have?"

The answer would be A + 8 slices.

Answer:

1479 gm

Step-by-step explanation:

V = 10 * 3 * 5 = 150 cm^3

150 cm^3  * 9.86 g / cm^3 = 1479 gm

Answer:

(6, 0 )

Step-by-step explanation:

to find where the line crosses the x- axis, let y = 0 in the equation and solve for x

0 = x - 6 ( add 6 to both sides )

6 = x

the line crosses the x- axis at (6, 0 )

Instead of y write 0:

0=x-6

0=x-6

6=x or x=6

We know the x coordinate of the point that intersects the x axis; the y coordinate is always 0.

(6, 0)

The value of sin D,  sin E , cos D , and cos E in simplest fraction form are as follows:

Sin D = 4 / 5

sin E = 3 / 5

cos D = 3  / 5

cos E = 4 / 5

The simplest trigonometric ratios expression are as follows:

Therefore,

Sin D = opposite / hypotenuse = 12 / 15 = 4 / 5

sin E = opposite / hypotenuse = 9  / 15 = 3 / 5

cos D = adjacent / hypotenuse = 9 / 15 = 3  / 5

cos E = adjacent / hypotenuse = 12 / 15 = 4 / 5

Answer:

The Numbers are rounded btw

Sin D = 28.1   As a fraction 281/10

Cos D = 31.9  As a fraction 319/10​

Cos E = 31.9  As a fraction 319/10​

Step-by-step explanation:

Sin= opposite/ hypotnuse

Con= addjacent/ hypotnuse

if you cant tell which side the hypotnues if on, it is always opposite from the 90 degree mark.

Now that you know how to make the fraction for Sin and Con, you would have to use a graphing calulator, plug in Sin^-1  or Con^-1 what ever the sign is and put the fractions in (  ) next to it and it will give you the decmle. Also using a graphing calculator is 100% allowed in this type of math.

Answer: 73

Step-by-step explanation:

Angle B is 180-107=73

Angle 1 is equivalent to B and it is 73

Answer:

C.  ∠1 = 73°

Step-by-step explanation:

Angles on a straight line add up to 180°

Therefore:

⇒ ∠1 + 107° = 180°

Subtract 107° from both sides:

⇒ ∠1 + 107° - 107° = 180° - 107°

⇒ ∠1 = 73°

Answer:

Step-by-step explanation:

7 and 2 are the two factors of 14.

One of them (and only 1) must be minus. That is the only way that you can get a minus 14.

The 7 must be plus. It has to larger than 2 in order to get + 5

Answer (x + 7)( x - 2) is how it factors.

Note

Always try using logic on the trinomial before going into the quadratic equation. If either the 5 is minus or the 14 is minus when one of the factors is minus. The sign in front of the middle number is the same as the larger of the two factors. So 7 must larger than 2. 7 is plus 2 is minus

Step-by-step explanation:

0.25 cup of lemon juice every 1 cup of water.

If you multiply it 4 times it would be 1 cup of lemon juice for every 4 cups of water.

Answer:

B) 24

Step-by-step explanation:

distance = 6 km

we want the speed in km/h, so let's turn everything into either km or h if possible

time = 7:45 am - 7: 30 am = 15 minutes

60 minutes = 1 hour

1 hour / 60 minutes = 1

15 minutes * 1 = 15 minutes * 1 hour/60 minutes = 15 / 60 hours = 1/4 hours = 0.25 hours

note that we multiply by 1 hour / 60 minutes, not 60 minutes/ 1 hour. this is because we want the minutes to cross out -- because the original is given in minutes ( 15 minutes = 15 minutes/1) and is in the numerator, we need minutes in the denominator of 1 hour/60 minutes to cross it out

km = 6

h = 0.25

km/h = 6/0.25 = 24

H. 12 ft

Given c=15, and a=9, you can use Pythagorean’s theorem a^2+b^2=c^2 to find b, the height

9^2+b=15^2

81+b^2=225

b^2=144

b=12

Height = 12

Explanation: Ratio seldom compares two numbers by dividing them (this depends on the problem). We are given A 16 computers and B 26 chairs. Therefore we have the formula of A/B.For example 16/26

Solving: Divide A by B: 16/26= 0.615 or 0.6

Multiple: Multiple the quotient by 100 in order to get the percentages. 0.615 x 100 = 61.5% (if you rounded 0.61, the answer would be 60%; for this problem I didnt round hence, 61.5%)

Answer: 61.5 %

Option D is correct. The number of team members who prefer tacos is the same as the combined number of team members who prefer hamburgers or pizza.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

Coach Rodriguez is planning an end-of-season celebration for the swim team.

To decide what food to serve, she surveys a random sample of students on the team Food for End-of-Season Celebration.

We can see that,

The number of team members who prefer tacos = 12

The combined a number of team members who prefer hamburgers or pizza = 7 + 5

         = 12.

So, The number of team members who prefer tacos is the same as the combined number of team members who prefer hamburgers or pizza.

The inference supported by the data collected in the survey would be option D.

The incorrect claim is A. He is incorrect. The path will have an area of (4)(40)=160 sq ft. The yard has an area of 600 sq ft. The area of the lawn will be the difference of the yard and path, so it is 440 sq ft.

This refers to the quantity used in mathematics to show the extent of a two-dimensional region, shape, or planar lamina, in the plane.

Hence, because Roy wants to make a path from one corner of his yard to the other, he makes an incorrect claim about the area of the yard and the lawn, and option A is the correct answer.
