Duane And his family are playing a game Dwayne scores 11 points each tile matches 1/3 point model the solution with an equation how many tile matches this Dwayne make
Answer:
33 tiles
Step-by-step explanation:
Given
[tex]1\ tile = \frac{1}{3}\ points[/tex]
Required
Determine the number of tiles in 11 points
Represent this with x. So, we have:
[tex]1\ tile = \frac{1}{3}\ points[/tex]
[tex]x = 11\ points[/tex]
Cross Multiply
[tex]x * \frac{1}{3} = 11 * 1[/tex]
Multiply through by 3
[tex]3*x * \frac{1}{3} = 11 * 1*3[/tex]
[tex]x = 33[/tex]
Explain how you can use ratios of the side lengths to find the angle measures of the acute angles in a right triangle.
Answer:
The answer is below
Step-by-step explanation:
Triangles are polygons with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled triangles.
Trigonometric identities are equations that uses trigonometric functions to show the relationship between the angles in a right angle triangle and the sides of the right angled triangle.
If θ be an acute angle in a right angled triangle, hyp. is the hypotenuse side of the angle, opp. is the opposite side to the angle and adj. is the adjacent side to the angle, then:
sinθ = opp. / hyp.v; cosθ = adj. / hyp. ; tanθ = opp. / adj.

I need help really fast!!!
Answer:
by using Pythagoras law
16²=(2x²)²+(2x²)²(since base angle of isosceles triangle is equal
16²=4x⁴+4x⁴
16²=16x⁴
16=x⁴
[tex]x = \sqrt[4]{16} [/tex]
x=2
If someone can help that would be great
Answer:
x = 16
Step-by-step explanation:
For the triangle to be isosceles then AB = CB , that is
5x - 9 = 4x + 7 ( subtract 4x from both sides )
x - 9 = 7 ( add 9 to both sides )
x = 16

f(x) =
-2x + 3,0 < x < 4
) -7

Answer:
it's 4 on edge
Step-by-step explanation:
I got it right
The value is in the domain of f(x) is 4, the correct option is C.
What is the domain and range of the function?
The domain of a function is defined as the set of all the possible input values that are valid for the given function.
The range of a function is defined as the set of all the possible output values that are valid for the given function.
We are given that;
f(x) =-2x + 3,0 < x < 4
Now,
The domain of a function is the set of all possible input values for which the function is defined. In this case, the function f(x) is defined by two different expressions depending on the value of x. The first expression, 2x + 5, applies when -6 < x < 0. The second expression, -2x + 3, applies when 0 < x < 4. Therefore, the domain of f(x) is the union of these two intervals:
Domain of f(x) = (-6, 0) U (0, 4)
Therefore, by the domain the answer will be 4.

Angel repairs used furniture. He expects to use 48 oz of wood filler this month. There are 16 oz in 1 lb. How many pounds of wood filler does Angel expect to use this month?
Answer: 3
Step-by-step explanation:
48 divided by 16 is 3
The number of pounds expected to use this month is 3 pounds.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
16 oz = 1 lb
Multiply 3 on both sides.
48 oz = 3 lb
Thus,
3 pounds of wood is in 48 oz.

Rashid can do a piece of work in 8 days, which Tipu can finish in 12 days. If they work on alternate days with Rashid Beginning, in how many days, the work will be finished?
Answer: 9.6 days
Step-by-step explanation:
Rashid can do a piece of work in 8 days. Rashid work rate will then be:
= 1/8 owe day.
Tipu can finish in 12 days. Tipu's work rate will be: = 1/12 owe day.
Their work rate together will then be:
= 1/8 + 1/12
= 3/24 + 2/24
= 5/24
From the calculation, together they will finish the work in:
= 1 ÷ 5/24
= 1 × 24/5
= 24/5 days
= 4.8 days
Busy since they are working on alternate days, then this will be multiplied by 2 which will be:
= 4.8 × 2
= 9.6 days

Each plate contained only 1 type of item and every plate had exactly the same number of items. There were no leftovers. What is the greatest number of items that could have been placed on each plate? Wellness Sale Donations Celery 63 Cucumbers 14 Carrots 35 The greatest number of items that each plate could have is nothing items. (Type a whole number.)
Answer:
The greatest number of items on each plate is 7

what are the rules for multiplying negative numbers?
Answer:
When multiplying negative numbers, just remember 2 things. 1: 2 negative values will always give a positive value. 2: If you only have 1 negative value, your answer will also be negative. Just remember these rules and the rest is simple multiplication.
Answer:
Hi there! Your answer is down below!
Step-by-step explanation:
The rule of how to multiply negatives is simple: For a case where a negative number is multiplied by a positive, the rule above can be restated as: take the positive number, and the negative WITHOUT the minus sign, multiply them and add the inus sign to the product.

1.A five - layer of cake weighs half a kilogram per layer.In each layer,the cake is decorated with icing which weighs 15g.3 candles which weighs 100g each is added.What is the total weight in kilogram of the fully decorated cake?
Answer: 2.815 kilograms
======================================================
Work Shown:
1 layer = 0.5 kg
5 layers = 5*(0.5 kg) = 2.5 kg
icing = 15 g = 15/1000 = 0.015 kg
1 candle = 100 g = 100/1000 = 0.1 kg
3 candles = 3*(0.1 kg) = 0.3 kg
------------------------
The five layers combine to 2.5 kg. On top of that we have 0.015 kg of icing, and then finally the three candles add 0.3 kg more weight.
The total weight is therefore: 2.5+0.015+0.3 = 2.815 kilograms
