Answers

Answer:

5/14 or .36

Turn 1/7 into fourteenths and add.

Answer:

5/14

Step-by-step explanation:

Steps for adding fractions

Find the least common denominator or LCM of the two denominators:

LCM of 14 and 7 is 14

Next, find the equivalent fraction of both fractional numbers with denominator 14

For the 1st fraction, since 14 × 1 = 14,

3/14 = 3 × 1/14 × 1 = 3/14

Likewise, for the 2nd fraction, since 7 × 2 = 14,

1/7 = 1 × 2/7 × 2 = 2/14

Add the two like fractions:

3/14 + 2/14 = 3 + 2/14 = 5/14

So, 3/14 + 1/7 = 5/14

Answer:

y=2x-7, the slope is two and the y-intercept is -7

Step-by-step explanation:

2(x-3)=y+1

Distributive prop.

2x-6=y+1

Changing into slope-intercept form

y+1=2x-6

Subtract both sides by one

y=2x-7

The slope is two and the y-intercept is -7

12. A rectangle has a height of 1 and 3/4 feet. The
area is 5 and 5/6square feet. What is its length?

Answers

Answer:

L = 3 1/3 feet

Step-by-step explanation:

A = length × width

now let's change all the mixed numbers into improper fractions:

35/6 = 7/4 × L

we must divide each side by 7/4

35/6 ÷ 7/4 is the same as 35/6 × 4/7 = 20/6 or 3 1/3

Nardia plots points showing equivalent ratios on the coordinate plane below. Mc018-1. Jpg Which ordered pair would represent a ratio that is equivalent to those shown? (6, 12) (9, 6) (8, 12) (12, 8).

Answers

The ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)

Ratio and proportions

From the given diagram, we can create two coordinate points which are (2, 3) and (4, 6)

We need to determine the ordered pair would represent a ratio that is equivalent.

Multiplying the coordinate by a scale factor of 4 will give

A(2, 3) = A'(4(2), 4(3)) = (8, 12)

Hence the ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)

An ambulance travels at 40 mph and can follow a 20-mile route making no stops to get to the hospital. A helicopter travels at one mile per minute, and the air route is 15 miles to get to the same hospital. However, the helicopter takes three minutes for takeoff and three minutes for landing. How many fewer minutes does it take for the helicopter to complete its trip (takeoff, flight and landing) than for the ambulance to complete its trip

Answers

Answer:

  9

Step-by-step explanation:

The time required by the ambulance is ...

  time = distance/speed

  time = (20 mi)/(40 mi/h) = 1/2 h = 30 minutes

The time required by the helicopter is ...

  trip time = takeoff time + route time + landing time

  = (3 min) + (15 mi)/(1 mi/min) +(3 min) = (3 + 15 + 3) min = 21 min

The difference in times is ...

  (30 min) -(21 min) = 9 min

The helicopter takes 9 fewer minutes for the trip.

what does cos mean in math?

Answers

Answer:

  cosine

Step-by-step explanation:

"cos" is an abbreviation for "cosine," the name of the trig function that relates the hypotenuse of a right triangle to the length of the side adjacent to the angle of interest.

For an angle measured in radians, the value of the cosine of the angle is defined by the power series shown in the second attachment. Any scientific or graphing calculator can evaluate this function. Generally, best accuracy from a calculator is obtained for angles between -2π and +2π radians, or ±360°. Calculators generally can use angles expressed in degrees or radians, so care is required to make sure the calculator mode matches the units you are using. (Spreadsheet functions typically require angles to be in radians.)

The cosine function is periodic, with a period of 2π radians. Its value for x=0 is 1. A graph of the cosine and sine (abbreviated "sin") functions is shown in the third attachment. Each is a horizontal shift of the other.

__

The three primary trig functions relate pairs of sides of a right triangle to one of the acute angles. The relationship between trig functions and sides is summarized in the mnemonic SOH CAH TOA. The first attachment shows what that means.

(25+45+50+36+x)/5=43
(156+x)/5=43
156+x=215

Which of these numbers is irrational?
A. 12
B. -4.2
C. 1/42
D. 4.2

Answers

Answer:

A: 12

Step-by-step explanation:

An Irrational Number is a real number that cannot be written as a simple fraction.  (Irrational means not rational).

Therefore, we can immediately discount C as 1/42 is a rational number by inspection.

[tex]4.2=\frac{4.2}{1} =\frac{4.2}{1} \times \frac{10}{10} =\frac{42}{10}=\frac{21}{5}[/tex]  so  similarly -4.2 = -21/5

So as B and D can also be written as rationals, they are not irrational.

Therefore, A is irrational.
