Answer 2

Answer:

m∠3 = 78

Step-by-step explanation:

Okay, since a triangle has 3 sides, we only need to find the measure of m∠3.

A triangle is made up of 180 degrees, so we can make an equation with 180 as what the equation is equal to.

Since m∠1 = 70, and m∠2 = 32, we will add those together with a variable x,

70+32+x=180

70 plus 32 is 102.

102+x=180

To get 102 to the other side we need to do the opposite of addition, which is subtraction.

180-102=78

So the answer is 78.

What is 1 and 1/4 minus 3/8?

Answers

Answer: 7/8

Step-by-step explanation:

You can change all the fractions to have equivalent denominators.

The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.

1 1/4 = 1 2/8 = 10/8.

3/8 = 3/8.

Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.

10/8 - 3/8 = 7/8.

Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.

A unit rate is a rate in which the _ in the comparison is 1 unit.

Answers

Answer:

3.1415967382

Step-by-step explanation:

A unit rate is a rate in which the second quantity, or denominator, in the comparison is 1 unit. You can find the unit rate by dividing the first quantity in a relationship by the second quantity.

Bonus:

The most common second quantity in rates, from personal experience, is the denominator in a fraction, like the 1 in 50/1. This is because the denominator is seen as the one specifying the unit. For example, in the rate "a car goes 50 miles per hour," the numerator would be the distance the car is traveling, which is 50, whilst the denominator would be the time the car takes to drive a certain distance - in this case, 1 hour. The first quantity is 50 miles and the second quantity is 1 hour. We can divide the first quantity by the second to get the fraction 50/1, which is a unit rate because the denominator (second quantity) has a value of 1. This also applies to values such as 90/3, where we would be trying to simplify the fraction to get a denominator value of 1.

Jesse measured his height to be 67 inches. His actual height is 68.5 inches. What is the percent error for Jesse's measurem

Answers

Answer:

2.24%

Step-by-step explanation:

Given that :

Actual height = 68.5

Measured height = 67

Percentage error :

(Error value / True value) * 100%

Error = Actual - observed = (68.5 - 67) = 1.5

Percentage error :

(1.5 / 67) * 100%

0.0223880 * 100%

= 2.2388%

= 2.24%

(HELP ILL GIBE BRAINLIEST AND A FREE THANKS) Which expression uses exactly three terms and is equivalent to
6(2 + x + x + y)?


A 12 + 12x + 6y


B 8 + 6x + 6x + 6y


C 12 + 6x + 6x + 6y

Answers

The answer is A it works out in order

The Equivalent Expression is 12 + 12x + 6y.

Therefore, option A is correct.

What is Expression?

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the expression: 6(2 + x + x + y)

Using Distributive property

a x ( b + c + d) = ab + ac + ad

So, the simplified expression is

= 6(2 + x + x + y)

= 6(2) + 6(x) + 6(x)+ 6(y)

= 12 + 6x + 6x + 6y

= 12 + 12 x + 6y

So, the Equivalent Expression is 12 + 12x + 6y.

A cyclist travels at an average speed of 20 km/h over a distance of 40 km.
How many hours does it take him?

Answers

Answer:

Given that speed(v) = 20km/h and time(t) = 50 min

We have to find distance (d)

First convert speed into m/s

v = (20*1000m)/(1*3600s)

v = (50/9) m/s

Now convert time into second

t = 50*60 = 3000 sec

As we know that

d = v*t = (50/9)*3000 = 50000/3

d = 16666.67m or 16.67km

Ans: 16666.67m or 16.67km

Step-by-step explanation:

Answer is equal to
