Answer:

true.

A chord that passes through the center of a circle is called a diameter and is the longest chord.

Step-by-step explanation:

A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

Answer:

15 chips and 8 pretzels

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Total spent = $7.75

Number of snacks = 23

Chips cost = $0.25

Pretzels cost = $0.50

Let number of chips = X

So, number of pretzels = 23 - X

So, we can calculate number of snacks by using following equation

0.25X + 0.50 ( 23 - X) = $7.75

0.25X + 11.50 - 0.50X = 7.75

0.25X - 0.50X = 7.75 - 11.5

-0.25X = -3.75

X = -3.75 ÷ -0.25 = 15

Hence, Number of chips = 15

Number of Pretzels = 23 - 15 = 8

Step-by-step explanation:

Calculate the frames of each month:

January = 350

February = 100

March = 250

April = 300

Solve

[tex]\frac{March}{Total} = \frac{250}{350 + 100 + 250 + 300} = \frac{250}{1000}[/tex]

Answer:

(-2,1)

Step-by-step explanation:

Substitute the value of y (x+3) from one equation into the second equation (2x+5)

X+3 = 2x + 5

add -2x to both sides

-x+3=5

add -3 to both sides

-x=2

x=-2

substitute -2 for x in either equation to find y.

y=-2+3

y=1

Check your answer by substituting x and y into either equat to make sure it equals.

y=x+3

1=-2+3

1=1

or

y=2x+5

1=2(-2)+5

1=-4+5

1=1

Answer:

u+133°=180

u=180-133

u=47°

Answer:

U = 47

T = 86

Step-by-step explanation:

133 + U = 180 ( straight line)

or, U = 180 - 133

or, U = 47

Being isosceles triangle

47 + 47 +T = 180

or, 94 + T = 180

or, T = 180 - 94

or, T = 86

Answer:

y=91

.........???????

Answer:

Every straight line can be represented by an equation: y = mx + b. ... The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:

6/11 divided by 2 2/3 (=9/44)

2/7 divided by 4/5 (=5/14 or 15/42 scaled up)

1 6/7 divided by 3 (= 13/21 or 26/42 scaled up)

3/10 divided by 1/8 (=2 2/5)

Step-by-step explanation:

You cannot divide a fraction by a fraction. Instead, multiply by the reciprocal ( flip it)

2/7 divided by 4/5= 2/7 x 5/4

Multiply straight across the top, 2x5= 10

10 is the numerator

Now multiply straight across the bottom.

7x4= 28

28 is the denominator.

10/28 is the answer to this problem, however it can be simplified. Both 10 and 28 are divisible by 2. This simplifies to 5/14.

For mixed numbers, you first have to make them improper fractions.

Ex: 2 2/3

Take the denominator (3) multiply it by the whole number (2) and add the numerator (2)

3x2=6 (now add the remaining 2 from the numerator) 6+2= 8. 8 is your new numerator and you will keep the existing denominator of 3 making the improper fraction 8/3.

The sequence that fulfills all the conditions is 4% of 250 = 10.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

From the table and a bit of thinking, we can construct a sequence that has whole value and percentage value as integers.

After trying with different sequences and by hit and trial we found a sequence that is,

4% of 250 = 10 which fills all the conditions.

Answer:

0.64π rad

Step-by-step explanation:

The formula for calculating the length of an arc is expressed as;

length of an arc = theta/360 * 2πr

r is the radius = 13 feet

arc length = 26feet

Substitute

26 = theta/360 * 2(3.14)(13)

26 = 81.64 theta/360

81.64 theta = 26 * 360

81.64 theta = 9360

theta = 9360/81.64

theta = 114.64

Hence the radian measure is 114.64/180 π = 0.64π rad

Answer:

2676 students

Step-by-step explanation:

Total number of students =. 40,140

During study:

Sample size = 210

Number of samples who speak 3 or more languages = 14

Proportion who speak 3 or more languages :

14 / 210 = 0.0666666

Applying the proportion to the total. Population :

0.0666666 * total number of students
