Please help I need help with #17, 19, and 21

Answers

Answer:

Step-by-step explanation:

All the angles in a triangle have to add up to 180 degrees.

#17.)

45+50=95

180-95=85

x=85

#18.)

This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.

180-118=62.

25+62=87

180-87=93

x=93

#21.)

For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.

180-108=72

x+x+2+72=180

2x+74=180

2x=106

x=53

Answer

#17=85

jackie made bracelets for 8 days. when he was done he had 96 bracelets. write and equation to express how many bracelets jackie made each day.

Answers

96 divided by 8.
Answers 12 bracelets per day

Answer:

12 bracelets.

Explanation:

If we assume Jackie made the same number of beaded bracelets each day, we can divide the total number of bracelets 96, by the amount of days it took to make all the bracelets, 8. This gives us  

  [tex]\frac{96}{8}[/tex]=12

We can check the answer by working backwards. Each day 12 bracelets were made. There were 8 days.  12 × 8 = 96 .  So for 8 days 12 bracelets were made giving Jackie 96 bracelets.

Angles DEF and PQR are supplementary. Which is the value of x? (x-6) (2x+42) A 18 B. 48 C. 132 D. 42​

Answers

Answer:

x = 48

Step-by-step explanation:

(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰

x - 6⁰ + 2x + 42⁰ = 180⁰

x + 2x - 6⁰ + 42⁰ = 180⁰

3x + 36⁰ = 180⁰

3x + 36⁰ - 36⁰ = 180⁰ - 36⁰

3x = 144⁰

3x / 3 = 144⁰ / 3

x = 48

Hope this helps, thank you :) !!

The answer is x = 48

A trapezoid was broken into a triangle and rectangle.

The area of the rectangle is cm2.
The area of the triangle is cm2.
The area of the trapezoid is cm2.

Answers

Answer:

Step-by-step explanation:

Base x Height = Area

10x12=120 the area of the rectangle is 120

area of the triangle is 28

sorry but I don't know the trapezoid

The area of the rectangle is 120 cm².

The area of the triangle is 24 cm².

The area of the trapezoid is 144 cm².

What is a trapezoid?

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.

We know, the area of a triangle is (1/2)×base×height and the area of a rectangle is (length×width).

Therefore, From the given information,

The area of the triangle is, (1/2)×4×12 = 24cm².

And the area of the rectangle is, (10×12) = 120 cm².

Therefore, The area of the trapezoid is,

= (24 + 120) cm².

= 144 cm².

Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop 0.3, 0.7,0.2, 0.6,0.9 then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration). If 0.6, 0.8, 0.75 was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration). These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows. a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1 b. Add a loop around the code created in Part a that continues until counter equals 3. c. Use the variable numlterations to count how many times your loop iterates. The numerator of a fraction is 9 and the denominator is 6.
