Answer:

11/12

Step-by-step explanation:

Given the expression 1/3 + a = 5/4

Subtract 1/3 from both sides

1/3 + a - 1/3 = 5/4 - 1/3

a = 5/4 - 1/3

a = 15-4/12

a = 11/12

Hence the value of x is 11/12

Answer:

Total number of students= 1,200

Step-by-step explanation:

Giving the following information:

Proportion of students= 10%

Number of students that travel by bus= 120

To calculate the number of students that attends school, we need to use the following formula:

Total number of students= Number of students that travel by bus / proportion of students

Total number of students= 120 / 0.1

Total number of students= 1,200

Answer:

Step-by-step explanation:

The interior angle measure of a regular polygon is calculated with 180*(n-2)/n, where n represents the number of sides.

A regular octagon has 10 sides so it interior angle = 180*(10-2)/10

= 144

A tessellation is a tile pattern with the same polygon repeating. The polygon's interior angles must combine to form 360 degree. A regular octagon has interior angle of 144 degree which does not add to 360 degree. So a regular octagon cannot be used as the only shape in a regular tessellation.

The answer is 144°, no.

Answer:

Step-by-step explanation:

oct means 10

(n-2)/n * 180

= (10-2)/10 * 180

= 144°

144 + 144 = 288 < 360

144 + 144 + 144 = 432 > 360

so a regular octagon can NOT be used as the only shape in a regular tessellation.

Step-by-step explanation:

Answer: Number of students tickets were sold = 120

Number of adults tickets were sold = 200

Step-by-step explanation:

Let x= Number of adults, y = Number of students

As per given,

x+y=320    ...(i)

4x+2.5y=1100 ...(ii)

Multiply 2.5 on both the sides of (i), we get

2.5x+2.5y=800   ...(iii)

Subtract (iii) from (ii), we get

1.5x=300

[tex]x=\frac{300}{1.5}\\x=200[/tex]

From (i) y= 320-200 = 120

Hence, Number of students tickets were sold = 120

Number of adults tickets were sold = 200

Answer:

814?

Step-by-step explanation:

Simple interest is I = PRT, so you can multiply the 550, by 1.08 by 6 to get the total.

The principal is 550, the rate is 0.08 (using 1.08 because the prior gives interest, and using a whole 1 with it will be the total), and the time is 6 years because the interest is simple annual.

use 0.08 instead of 1.08 when solving for interest.

Answer:

Cost of Blanket = 32

Step-by-step explanation:

Let the cost of a blanket be = b , cost of a scarf be = s. Blanket price x Blanket Quantity & Scarf Price x Scarf Quantity sum up to be total sales.

So, Day 1 : 2b + 5s = 104 (i)  , Day 2 : 3b + 4s = 128 (ii)

Solving equations : Multiplying (i) by 3 , & (ii) by 2 , we get

6b  +  15s    =   312 ,

(-)6b + (-)8s =  (-)256

By elimination method, 15s - 8s = 312 - 256 → 7s = 56 → s = 56 / 7 = 8 .

Putting s value in any equation i], 2b + 5 (8) = 104 → 2b + 40 = 104 → 2b = 104 - 40 = 64 → b = 64 / 2 = 32

The ratio that represents the sine of ∠B is 15/17.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Since the triangle has a right angle, we can find the length of the unknown side using the trigonometric notations SOH CAH TOA where;

Sin Ф = opposite side/hypotenuses side

Cosine Ф = adjacent side/hypotenuses side

Tangent Ф = opposite side/adjacent side

With respect to ∠B given that  ∠D=90°,

BD is the adjacent side and CB  is the hypotenuse side, DC is the opposite side

Hence ,Sin B = 15/17

Answer:

Jerry's data points have to sum to be 77.

Step-by-step explanation:

We are given that

Ben and Jerry both have total numbers in their data set=7

Average of Ben's data set=9

Average of Jerry's data set=9+2=11

We have to find the Sum of Jerry's data points.

We know that

Average of data=Sum of numbers/Total number of data points

Using the formula

Average of Jerry' data =Sum of numbers in data/7

11=Sum of numbers in data/7

Sum of numbers=[tex]11\times 7[/tex]

Sum of numbers=77

Hence, sum of Jerry' data points=77

Answer:

1 /3

Step-by-step explanation:

Bag 1 :

Yellow = 3 ; green = 2 ; red = 1

Total = 6

P(not yellow) = (2 +1) / 6 = 3/6 = 1/2

Bag 2 :

Yellow = 3 ; green = 3 ; red = 3

Total = 9

P(not yellow) = (2 +3) / 9 = 6/9 = 2/3

P(neither yellow from the two bags) = 1/2 * 2/3 = 2 /6 = 1/3

Answer:

rate of change=5

Step-by-step explanation:

Hi there!

The rate of change (or the slope) is calculated from two points with the formula (y2-y1)/(x2-x1)

we are given two points: (1,-1), and (2,4)

let's label the points, to avoid confusion:

x1=1

y1=-1

x2=2

y2=4

now substitute into the formula:

*note: remember that we are subtracting the negative numbers. When it's simplified, we add the numbers.

rate of change=(4--1)/(2-1)

simplify:

rate of change=(4+1)/(2-1)

rate of change=5/1

rate of change=5
