An isosceles triangle has base angles that each measure 42 degrees.Which equation can be used to find z, the measure of the third angle of this isosceles triangle in degrees

Answers

Answer 1

Answer:

z+42+42=180

Step-by-step explanation:

Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to  180. So use this equation:

z+42+42=180

If you need to find z, it is 96.

Check: 96+42+42=180

what is the answer to 4(x + 1) = 4x + 10

Answers

Answer:

No solution

Step-by-step explanation:

First we would have to see if anything has to be distributed and yes the 4 in the expression 4(x + 1) has to be distributed to the x and 1. So we would multiply the 4 by x and 1. Now we have 4x + 4 = 4x + 10. We have to get the x's on 1 side of the equation so we would do the inverse of one of the x's and we can only subtract. So we can subtract 4x on both sides. So now we have

4 = 10. That isn't a correct statement so there is no solution.

4 does not equal 10.

The Ironman endurance race has a 2.4 miles swim. Javier can swim 0.5 miles in 20 minutes. If he can continue this pace, it will take him hours to finish the swim event.

Answers

Given :

The Ironman endurance race has a 2.4 miles swim.

Javier can swim 0.5 miles in 20 minutes.

To Find :

How much time in hours it takes to complete the race.

Solution :

Speed of Javier :

[tex]s=\dfrac{2.4}{\dfrac{20}{60}}\ mph\\\\s= 7.2\ mph[/tex]

Let, time taken to cover 2.4 miles is t .

So,

[tex]t = \dfrac{2.4}{7.2}\ hours\\\\t = 0.33\ hours[/tex]

Hence, this is the required solution.

The value of (f o g)(-1) is 1 if the function f(x) =  8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

Two functions:

f(x) =  8/(x + 2)

g(x) = 4x² + 2

g(-1) = 4(-1)² + 2

g(-1) = 4 + 2

g(-1) = 6

f(g(-1)) = 8/(x + 2)

f(g(-1)) = 8/(6 + 2)

f(g(-1)) = 8/8

f(g(-1)) = 1

Thus, the value of (f o g)(-1) is 1 if the function f(x) =  8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

A scooter travels 30 feet in 2 seconds at a constant speed.
What is the speed of the scooter in feet per second?

Answers

Answer:

15

Step-by-step explanation:

Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.

To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2

Brainliest pls

The speed of the scooter is 15 feet per second.

To calculate the speed of the scooter in feet per second, you can use the formula:

Speed = Distance / Time

The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.

Plugging these values into the formula, we get:

Speed = 30 feet / 2 seconds

Speed = 15 feet/second

Therefore, the speed of the scooter is 15 feet per second.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A typical car releases 36 tonnes of carbon dioxide and six years.

Let 'x' be the amount of carbon dioxide.

At a constant rate, the number of tonnes of carbon dioxide released in 10 years will be given as,​

x / 10 = 36 / 6

Simplify the equation, then we have

x / 10 = 36 / 6

x / 10 = 6

x = 60 tons

The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.
