Answer:

x = 10

Step-by-step explanation:

supplementary angles

y + 6x - 15 = 180

triangle

(2x+18) + (2x-13) + y = 180

simplify the above to get these equations

y + 6x = 195

y + 4x = 175

solve for system of equations by subtracting the second from the first and you get

2x = 20

x = 10 degrees

please give a like and brainly :)

(2) The sum of angles in a quad is always 360.

Take line RST and you get the value of angle RSP as 180 - 110 which is 70. This is due to them being linear pairs. Angles formed by a straight line is always 180 degrees!

110 + x = 180

x = 70

Now for y

Since we found values for all the 3 angles, which are 140, 110, 70, the 4th one is gonna be the sum of all the 3 angles subtracted from 360

140 + 110 + 70 + y = 360

y = 360 - (140 + 70 + 110)

y = 50 <- That's the answer.

(2) 2 of the angles are already given. If you look, angle U is 90 degrees. That's what the sign represents.

Angle Q (In the quad) is going to be 180 - 110 (Linear pairs) = 70

Since we found 3 angles the 4th one (angle R) is going to be 360 - (90 + 50 + 70) which is 360 - 210 which is 150.

Since angle R in the quad is 150, due to linear pair property, 3x = 180 - 150

3x = 30

x = 30/3 = 10

x = 10 <- That's the answer :D

The cost of Goods Sold will be $93.5

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

The Cost of Goods Sold for one Holiday Basket:

1 basket = $24.00 per dozen

2 lbs. Cheddar cheese = $1.50 per pound

1 canned ham = $60.00 per dozen

3 jars of jelly = $1.00 each

6 oranges = $2.00 per dozen

1 box crackers = 2.00 per box

Cellophane wrap = $.50 each

Now,

Since, Each basket has only one of each item in it.

So, The total cost = $24 + $1.50 x 2 + $60 + $1 x 3 + $1 + $2 + $0.50

                           = $93.5

Thus, The cost of Goods Sold will be $93.5

The z-score for Windex with a cost of 10.1 cents per ounce is 0.96.

To calculate the z-score, we need to first standardize the value of Windex in terms of the distribution of the cost per ounce of glass cleaner.

The formula for calculating the z-score is

z = (x - μ) / σ

Where

x = value of the variable (in this case, cost of Windex = 10.1 cents per ounce)

μ = mean of the distribution (average cost per ounce = 7.7 cents)

σ = standard deviation of the distribution (2.5 cents)

Plugging in the values, we get

z = (10.1 - 7.7) / 2.5

z = 0.96

The theoretical yield of Fe₂(SO₄)³ if 20.00 g of FePO₄ reacts with an excess of Na₂SO₄ is 26.52g.

The amount of a product produced by a reaction is expressed in terms of the reaction's yield.

Given the chemical equation:

2FePO₄ + 3Na₂SO₄ → Fe₂(SO₄)₃ + 2Na₃PO₄

Theoretical molar ratios:

2 mol FePO₄  : 3 mol Na₂SO₄ : 1 mol Fe₂(SO₄)₃ : 2 mol Na₃PO₄

Convert 20.00 g of FePO₄  into a number of moles

number of moles = mass in grams / molar mass

molar mass of FePO₄  = 150.82 g/mol

Number of moles = 20.00 g / 150.82 g/mol = 0.1326 mol FePO₄

Proportionality

1 mol Fe₂(SO₄)₃                x

----------------------- =  ------------------------

2 mol FePO₄            0.1326 mol FePO₄

Solve for x:

x = (0.1326 / 2) x 1 mol Fe₂(SO₄)₃ = 0.0663 mol Fe₂(SO₄)₃

Convert 0.0663 mol Fe₂(SO₄)₃ into grams

mass in grams = number of moles x molar mass

molar mass Fe₂(SO₄)₃ = 399.88 g/mol

mass = 0.0663 mol x 399.88 g/mol = 26.51 g

Depending on the number of decimal digits used by one or other you might obtain 26.52 instead 26.51, that difference does not count.

Therefore, the theoretical yield of Fe₂(SO₄)³ is 26.52g.

Answer:

The probability is 0.694

Step-by-step explanation:

Let the probability of getting a car washed be

P(W) = 72% = 0.72

Let the probability of getting a car vacuumed be

P(V) = ?

Probability of getting car washed and vacuumed is P(W n V) = 50% = 0.5

From Bayes’ theorem

P(V|W) is the probability that a customer gets their car vacuumed given that they are getting it washed

So mathematically;

P(V|W) = P(V n W)/P(W)

= 0.5/0.72 = 0.694

Answer:

angle don+angle gil=90°

don+ 74°=90°

don=90°-74°

don=16°

angle e + angle a=180°

128°+angle a=180°

angle a=180°-128°

angle a=52°

Answer:

1. 16°

2. 52°

Step-by-step explanation:

So!! Complementary angles add up to 90 degrees, and supplementary angles add up to 180 degrees. With this, it should be really easy. To find the measure of angle DON:

m∠DON + m∠OIL = 90°

m∠DON + 74°=90°

m∠DON=16°

For the measure of angle A:

m∠A+m∠E=180°

m∠A+128°=180°

m∠A=52°

a=d  1.co interior angle  2. are equal

b=c 1. co interior angle 2. are equal

A transversal that crosses two parallel lines creates alternate angles, which are a pair of angles. Alternative angles are often referred to as "Z-angles" or "alternate internal angles."

∠a=∠d (because co interior angle i.e, a and d are equal)

∠b=∠c (because co interior angle i.e, b and c are equal)

Both sides are parallel, so co interior angle rule satisfies.

Hence, a=d  1.co interior angle  2. are equal

b=c 1. co interior angle 2. are equal

Co-interior angles form between two parallel lines when a transversal crosses them. On the same side of the transversal, the two angles always sum to 180 degrees. Drawing a C shape helps us identify co-interior angles rather frequently. Only when both inner angles are 90 degrees are they equal.

The area of the triangle whose base is 4.1 miles and has a height of 1.7 miles is calculated as: 3.485 square miles.

To find the area of a triangle, you can use the formula:

Area = (1/2) * base * height

Given that the height is 1.7 miles and the base is 4.1 miles, we can substitute these values into the formula:

Area = (1/2) * 4.1 miles * 1.7 miles

Calculating the area:

Area = 0.5 * 4.1 miles * 1.7 miles

= 3.485 miles²

Therefore, the area of the triangle is 3.485 square miles.

The total is $38.1

Step-by-step explanation:

The tax is $2.1, The tip is $6.

Percentage is the part of the whole expressed in the fraction of hundred.

The total cost of the meal after the tip and tax is $38.1.

Percentage of a number or ratio expressed in the form of fraction of hundred.

Given information-

The total cost of meal before tax and tip is $30.

The total sales tax is 7%.

The tip added to the cost of meal is 20%.

As, the total sales tax is 7% and cost of the meal is $30. Thus the total sales tax amount is,

\(s_t=30\times\dfrac{7}{100} \\s_t=2.1\)

Thus the amount of sales tax is 2.1.

As the the tip added to the cost of meal is 20% and the cost of the meal is 32.1 after the tax. Thus the amount of meal after the 20 % tip is,

\(s_t=30\times\dfrac{20}{100} \\s_t=6.00\)

The amount of the tip of the meal after the tax is $6.00.

The cost of meal after the tip and tax is,

\(C=30+2.1+6\\C=38.1\)

Hence the total cost of the meal after the tip and tax is $38.1.

For the linear equation y = 2x 4, if x increases by 1 pointThe value of y will increase by 2 points(A).

The equation y = 2x + 4 represents a linear relationship, where the coefficient of x, which is 2, represents the slope of the line. The slope indicates how much y changes when x increases by 1. In this case, the slope is 2, meaning that for every increase of 1 in x, y will increase by 2.

Therefore, For the linear equation y = 2x 4, if x increases by 1 point,the value of y will increase by 2 points(A). This means that correct option is A.
