What is the measure of angle x
Answer:
x = 145°Step-by-step explanation:
by looking at the figure we notice that angles AOB and BOC are two supplementary angles which means:
x + 35 = 180
then
x = 180 - 35
then
x = 145

Rina is 6x + 3:8 feet tall and Ryan is 5x + 1/8 feet tall. How much taller is Rina than Ryan?
Answer: Rina is [tex]x+\dfrac{1}{4}[/tex] feet taller than Ryan.
Step-by-step explanation:
Given, the height of Rina = [tex]6x+\dfrac{3}{8}[/tex] feet
The height of Ryan = [tex]5x+\dfrac{1}{8}[/tex] feet
To find : How much taller is Rina than Ryan?
Clue : Rina is taller than Ryan.
For that , we need to check the difference of the height between Ryan and Rina
i.e. (height of Rina) - (height of Ryan)
[tex]=6x+\dfrac{3}{8}-(5x+\dfrac{1}{8})\\\\=6x+\dfrac{3}{8}-5x-\dfrac{1}{8}\\\\=x+\dfrac{3-1}{8}\\\\=x+\dfrac{2}{8}\\\\=x+\dfrac{1}{4}[/tex]
Hence, Rina is [tex]x+\dfrac{1}{4}[/tex] feet taller than Ryan.

Mrs.Garcia is making bread using a total of 400 grams of gluten free flour.The recipe calls for 70% of the flour to be almond flour. She needs to know how much almond flower to use.
Answer:
She needs 280 grams of almond flour.
Step-by-step explanation:
This question can be solved using a rule of three.
400 grams is 100% = 1. How much is 70% = 0.7?
400 grams - 1
x grams - 0.7
x = 400*0.7
x = 280
She needs 280 grams of almond flour.
Answer:
120g
Step-by-step explanation:
70% of flour in 400g is expressed as
= 70/100×400
=0.7×400
=280g
Therefore, the amount of almond flour to be used by Mrs Garcia in making the recipe is
=400g-280g
=120g
Thus, Mrs Garcia requires 120g of almond flour

The function f (t) =-16t^2 = 576 represents the height of a freely falling ballast bag that starts from rest on a ballon 576 feet above the ground. After how many seconds t does the ballast bag hit the ground.
Answer:
The ballast bag hits the ground after 6 seconds.
Step-by-step explanation:
Suppose there was a small typing mistake.
The height of the ball, after t seconds, is given by the following equation:
[tex]f(t) = -16t^{2} + 576[/tex]
After how many seconds t does the ballast bag hit the ground.
This is t for which f(t) = 0. So
[tex]f(t) = -16t^{2} + 576[/tex]
[tex]-16t^{2} + 576 = 0[/tex]
[tex]16t^{2} = 576[/tex]
[tex]t^{2} = \frac{576}{16}[/tex]
[tex]t^{2} = 36[/tex]
[tex]t = \pm \sqrt{36}[/tex]
Time is a positive measure, so
[tex]t = 6[/tex]
The ballast bag hits the ground after 6 seconds.

What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
It is given that Jacob took a total of 12 quizzes over the course of 3 weeks. The number of weeks for 16 quizzes will be calculated as below:-
12 quizzes = 3 weeks.
1 quizzes = 3 / 12 weeks
16 quizzes = ( 3 / 12 ) x 16 = 4 weeks
Therefore, the number of weeks for a total of 16 quizzes will be 4 weeks.

Erica has a small metal treasure box. The inside of the box is 3 inches wide, 6 inches long, and 4 inches deep. Erica wants to line the box with fabric to protect the items she puts in the box. How many square inches of fabric will she need? Show your work
Answer: she will need 108 square inches of fabric.
Step-by-step explanation:
To determine the number of square inches of fabric that she will need, we would determine the surface area of the inner part of the box. The formula for determining the surface area of a box or cuboid is expressed as
Surface area = (2lw + 2lh + 2wh)
Where
l represents length of the box = 6 inches
w represents width of the box = 3 inches
h represents height of the box = 4 inches
Therefore,
Surface area = (2 × 6 × 3) + (2 × 6 × 4) + (2 × 3 × 4) = 108 inches²

2.31 with the 1 repeating
Answer: [tex]\frac{104}{45}[/tex]
Step-by-step explanation:
[tex]2.31^-[/tex]
Let x be equal to that.
[tex]x=2.31^-[/tex]
Multiply by 1 followed by as many zeros as repeating numbers. In this case it's just one repeating decimal, therefore, 1 followed by 1 zero or 10.
[tex]10x=2.31^-*10[/tex]
This basically moves the decimal point one number to the right.
[tex]10x=23.11^-[/tex]
Subtract the first equation from this new equation.
[tex]10x=23.11^-\\-x=2.31^-[/tex]
--------------------------
The repeating decimal is eliminated and we are left with:
23.1
- 2.3
---------
20.8
We also have 10 - 1 = 9. We are left with:
[tex]9x=20.8[/tex]
Divide by 9.
[tex]x=\frac{20.8}{9}[/tex]
To get rid of the decimal, multiply by 1 followed by as many zeros as decimals. In this case 1.
[tex]x=\frac{20.8}{9} (\frac{10}{10} )[/tex]
[tex]x=\frac{208}{90}[/tex]
Let's simplify.
208/2=104
90/2=45

How many solutions does this equation have?
–2 − 10z = –4 − 10z
Answer:
No solutions
Step-by-step explanation:
To find out how many solutions there are you must solve:
- 2 - 10z = - 4 - 10z
Add 10z to both sides:
-2 = -4
Since the two terms are different from one another, that means that there are no solutions for this equation.

Answer:
4.71 miles
Step-by-step explanation:
Janet must run the length of the circumference of the circular lake.
The circumference of a circle is given as:
C = πD
where D = diameter of the circle.
The diameter of the circular lake is 1.5 miles. Therefore, its circumference is:
C = 3.14 * 1.5
C = 4.71 miles
She must run 4.71 miles.

There are a total of 193 member states (countries) in the united nations as of 2014.The member states are divided into regional groups. The asia group has one less member than the africa group. The european groups are smaller: eastern europe has four less than half the africa group. The western europe group (which includes the united states) has 6 more than eastern europe. The latin america group has 21. Less than the africa group. One country (kiribati, in the central pacific ocean) is in no regional group at all. How many countries are in each of the five groups?
Answer:
Africa = 54 countries
Asia = 53 countries
Eastern Europe = 23 countries
Western Europe = 29 countries
Latin America = 33 countries
Step-by-step explanation:
193 member states - Kiribati = 192 countries
Asia = Africa - 1
Eastern Europe = 0.5Africa - 4
Western Europe = 0.5Africa + 2
Latin America = Africa - 21
Africa
Africa + (Africa - 1) + (0.5Africa - 4) + (0.5Africa + 2) + (Africa - 21) = 192
4Africa - 24 = 192
4Africa = 192 + 24 = 216
Africa = 216 / 4 = 54
Asia = 54 - 1 = 53
Eastern Europe = 0.5(54) - 4 = 23
Western Europe = 0.5(54) + 2 = 29
Latin America = 54 - 21 = 33
Africa is = 54 countries
Asia is = 53 countries
Eastern Europe is = 23 countries
Then, Western Europe is = 29 countries
After that, Latin America = 33 countries
What is Logical Data Grouping?Then, 193 member states - Kiribati = 192 countries
After that, Asia = Africa - 1
Now, Eastern Europe = 0.5Africa - 4
Western Europe is = 0.5Africa + 2
Latin America is = Africa - 21
Africa
Africa + (Africa - 1) + (0.5Africa - 4) + (0.5Africa + 2) + (Africa - 21) = 192
4Africa - 24 = 192
4Africa = 192 + 24 = 216
Africa = 216 / 4 = 54
Asia = 54 - 1 = 53
Eastern Europe = 0.5(54) - 4 = 23
Western Europe = 0.5(54) + 2 = 29
Therefore, Latin America = 54 - 21 = 33

A square has an area of 9 cm^2. What is the length of each side?
Answer:
The side length is 3 cm
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
9 = s^2
Take the square root of each side
sqrt(9) = sqrt(s^2)
3 =s
The side length is 3 cm
Answer:
3cm
Step-by-step explanation:
As we know it's a square, we can just square the area to get:
[tex]\sqrt{9}[/tex] = 3
We know we can do this as to find the area of a square or rectangle you just need to multiply the sides together. As it's a square, all the sides are the same so they have the formula:
x * x = A (unit)^2
