Hey there!

The interior angles of a triangle always have to add up to 180 degrees.

We are told that this is a right triangle, so one of the angles must be 90 degrees. This means that the measures of the other two angles must add up to 90.

90 + m<1 + m<2 = 180

If the smallest angle is 45 degrees less than the next largest angle, the only option for this would be for both of the remaining angles to be 45 degrees. The next largest angle would be the right angle, and 90 -  45 = 45.

We can't have any of the other angles be more than 90 degrees because then it wouldn't be a proper triangle.

So, the measures of the angles are going to be 90, 45, and 45.

Hope this helps!

The measurement of the smallest angle in a right triangle is 45° less than the measure of the next larger angle. The three angle of right are ( [tex]90^o, 45^o, 45^o[/tex] )

In a right angle triangle, the largest angle is equal to the 90 degrees, and the some of the other two angle is equal to the 90 degrees.

Given information-

The smallest angle in a right triangle is 45° less than the measure of the larger angle.

Suppose the smallest angle of the right triangle is x degrees.

Now as the smallest angle in a right triangle is 45° less than the measure of the larger angle and the value of largest angle is 90 degrees in the right angle triangle. Thus,

[tex]x=90-45\\x=45^o[/tex]

Hence, the measurement of the smallest angle is 45 degrees.

Let the other angle of the right angle triangle is y degrees.

As the some of the all the angles of a triangle is equal the 180 degrees. Thus,

[tex]x+y+90=180\\45+y=180-90\\y=90-45\\y=45[/tex]

Thus, the measurement of the other angle is 45 degrees.

Hence, the measurement of the smallest angle in a right triangle is 45° less than the measure of the next larger angle. The three angle of right are ( [tex]90^o, 45^o, 45^o[/tex] )

Answer:

20 + 24 = 44

Hoped this helped :)

The equations are x + y = 44 and y = 2x + 2. Then the value of the two numbers is 14 and 30.

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

The sum of the two numbers is 44. One number is 2 more than twice the other.

Let the two numbers be 'x', 'y' and y > x. Then we have

x + y = 44             ...1

y = 2x + 2            ...2

From equations 1 and 2, then we have

x + 2x + 2 = 44

3x = 42

x = 14

Then the value of 'y' is calculated as,

y = 2 (14) + 2

y = 28 + 2

y = 30

The equations are x + y = 44 and y = 2x + 2. Then the value of the two numbers is 14 and 30.

Step-by-step explanation:

Final answer:

If m is greater than n, then all the provided inequalities must be true, as they involve either adding the same amount to both sides or increasing the positive difference between m and n.

Explanation:

If m > n, then certain inequalities must hold true when we add, subtract, or compare these variables while keeping the inequality relationship consistent. Here are the inequalities that must be true based on the given condition:

m + 2.1 > n + 2.1: Adding the same number to both sides of an inequality does not change the relationship, thus this inequality must be true.

m - (-4) > n -(-4): Subtracting a negative is the same as adding a positive, so this inequality will also hold true.

m + 3 > n - 3: Adding a positive number to m and a negative to n will increase the difference between them, making this inequality true.

16.5 + m > 16.5 + n: Similar to the first point, adding the same number to both sides of an inequality maintains the inequality.

m > n + 1/2: Since m is greater than n, adding a positive fraction to n would still keep m greater than the modified n.

9 + m  > 6 + n: Adding different numbers to m and n still preserves the inequality, if the number added to m is not smaller than the number added to n.

➷ First calculate how many counters are 'not white'

12 - 7 = 5

We have 5 counters that are 'not white'

The probability of taking a white counter the first time is 7/12

For the next pick, there would be 1 less of the total counters as it is not being replaced

The probability of then taking a 'not white' counter is 5/11

The other way you could still get one white counter is:

The first counter (non white) probability would be 5/12

The second counter (white) probability would be 7/11

Multiply these values:

7/12 x 5/11 = 35/132

5/12 x 7/11 = 35/132

Add these two values together:

35/132 + 35/132 = 70/132

Your answer is 70/132

The correct option is B.

The equation is B. 4c + 70 = 7c + 160, where c represents the number of candles sold by each girl.

To find the equation representing the scenario where both Hailey and Kacie have raised the same amount of money by selling candles, we can set up an equation based on the total amount raised by each girl.

Let's represent:

- Hailey's total amount raised as H

- Kacie's total amount raised as K

- The number of candles each girl sells as c

Given:

- Hailey's total amount raised, H = $160

- Kacie's total amount raised, K = $70

The equation representing the scenario where both Hailey and Kacie have raised the same amount of money by selling candles is:

4c (Hailey's selling price per candle) = 7c (Kacie's selling price per candle)

So, we have:

4c = 7c

To solve for c, we need to make the total amounts equal on both sides. We already have the total amounts raised by each girl:

Total amount raised by Hailey = $160

Total amount raised by Kacie = $70

Now, let's set up the equation:

4c (for Hailey) = 7c (for Kacie)

4c - 7c = 160 - 70

-3c = 90

Now, divide both sides by -3 to solve for c:

c = -90 / -3

c = 30

So, each girl needs to sell 30 candles to raise the same amount of money.

Therefore, the correct equation representing the scenario is:

B. 4c + 70 = 7c + 160

The complete question is here:

Hailey and Kacie are selling candles to raise money.

• Hailey is selling candles for $4 each and has already raised $160.

• Kacie is selling candles for $7 each and has already raised $70

Which equation can be used to find c, the number of candles each girl needs to sell so that the total amount raised is the same for both Hailey and Kacie?

A. 4c+7c=160+70

B. 4c+70=7c+160

C. 4c+160=7c+70

D. 4+160=7c+70c

Answer:

C

Step-by-step explanation:

Adding the given sum

[tex]\frac{3}{4}[/tex] + [tex]\sqrt{64}[/tex]

= 0.75 + 8 = 8.75

A rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] where a and b are integers

8.75 = [tex]\frac{875}{100}[/tex] ← a rational number

Answer: OPTION C

Step-by-step explanation:

Descompose 64 into its prime numbers:

[tex]64=2*2*2*2*2*2=2^6[/tex]

Rewrite the expression as following, and simplify:

[tex]=\frac{3}{4}+\sqrt{2^6}\\\\=\frac{3}{4}+2^3\\\\=\frac{3}{4}+8\\\\\frac{3}{4}+\frac{8}{1}[/tex]

Find the least common denominator:

 [tex]4=2*2*1=2^2*1\\1=1\\LCD=2^2*1=4[/tex]

Now you can make the addition:

[tex]\frac{(3*1)+(8*4)}{4}=\frac{3+32}{4}=\frac{35}{4}=8.75[/tex]

As 8.75 can be written as a fraction, then it is rational.

Final answer:

The expression that includes 3x and ¼ should be written as 3x + ¼. Also, it's important to note that in math, an equality like 1 yard equals 3 feet can be manipulated by multiplication or division and will still remain true.

Explanation:

It seems there's a typo in the expression you've provided (3x 2 1/4). However, if you are looking for how to express the quantity 3x plus ¼, then the expression would be written as 3x + ¼. This expression shows the addition of the fraction ¼ to the variable 3x.

Regarding the references provided about exact numbers and equalities, in mathematics, we can use this information to solve various problems that involve proportions or unit conversions. For example, knowing that 1 yard equals 3 feet is an exact number equality that can be used in many calculations. You can adjust this equality by multiplication or division, and it will still hold true. Thus, if you divide both sides by 2, you would get ½ yard equals 1½ feet, which is still a true statement.

The distance between the points (4,2) and (-8,7) is found by using the distance formula derived from the Pythagorean theorem. By substituting the coordinates into the formula, you can solve to find that the distance is 13 units.

The best way to find the distance between the points (4,2) and (-8,7) is to use the distance formula. The distance formula is derived from the Pythagorean theorem and is defined as follows:

 √[(x2-x1)² + (y2-y1)²]

Here, (x1, y1) and (x2, y2) are the coordinates of the two given points. For your points, x1=4, y1=2, x2=-8, y2=7.

By substituting these into the distance formula, we get √[(-8-4)² + (7-2)²] = √[(-12)² + (5)²] = √[144 + 25] = √169 = 13.

So, the correct answer is A. 13. Therefore, the distance between the points (4,2) and (-8,7) is 13 units.

The vertices of the image triangle ABC, after reflecting across the line (y = -1), are A' (4, 5), B' (1, 6), and C' (2, 3).

To find the image of the triangle ABC after a reflection across the line (y = -1), you can use the formula for the reflection of a point across a line.

The formula for the reflection of a point (x, y) across the line (y = mx + b) is given by:

[tex]\[\left(\frac{{x - m(y - b)}}{{1 + m^2}}, \frac{{y - m(x - a)}}{{1 + m^2}}\right)\][/tex]

In this case, the line of reflection is (y = -1), so (m = 0) and (b = -1). Therefore, the formula simplifies to:

[tex]\[\left(x, \frac{{y + 2}}{{1}}\right)\][/tex]

Now, apply this formula to each vertex of triangle ABC.

1. For point A(4, 3):

[tex]\[A' = \left(4, \frac{{3 + 2}}{{1}}\right) = (4, 5)\][/tex]

2. For point B(1, 4):

[tex]\[B' = \left(1, \frac{{4 + 2}}{{1}}\right) = (1, 6)\][/tex]

3. For point C(2, 1):

[tex]\[C' = \left(2, \frac{{1 + 2}}{{1}}\right) = (2, 3)\][/tex]

So, the vertices of the image triangle after the reflection across the line (y = -1) are A'(4, 5), B'(1, 6), and C'(2, 3).

Sam had 85$

James has 240+30=270 then 270/2 is 135

And because mom gave 50$ to sam subtract 50 135-50= 85 so sam had at first 85$

Final answer:

Sam had $170 at first given all the conditions.

Explanation:

Let's assume Sam had x dollars at first. Since James had $240 more than Sam at first, this means James had x + $240. After their mother gave James $30 and Sam $50, James had x + $240 + $30 and Sam had x + $50. We are told that after receiving the money, James had twice as much as Sam, which can be represented by the equation 2(x + $50) = x + $270. Solving for x, we get x + $100 = x + $270.

Subtracting x from both sides of the equation, we have $100 = $270, which is not possible, indicating a mistake has been made. We should redefine our equation as 2(x + $50) = (x + $240) + $30. Solving this correct equation, we get 2x + $100 = x + $270. Subtracting x and $100 from both sides, we find that x = $170. Therefore, Sam had $170 at first.

The focus is from the vertex is 5m.

Two or more expressions with an Equal sign is called as Equation.

The distance from the vertex of a parabolic surface to its focus depends on the shape of the parabola, and specifically on its focal length.

The focal length of a parabolic surface is given by the equation:

f = d²/ (16w)

where f is the focal length, d is the depth of the parabolic surface, and w is the width of the parabolic surface.

Plugging in the given values, we get:

f = 1² / (16 x20)

= 1/320 km

To convert this distance to meters, we multiply by 1000:

f = 1/320 x 1000 = 3.125 meters

Therefore, the focus is from the vertex is 5m.

To find the number of different pairs that can be made with four colors, we use the combinations formula C(4, 2), which calculates to 6. Thus, there are 6 different color pairs that can be made with red, blue, green, and purple.

To determine how many different pairs can be made with four colors: red, blue, green, purple, we use the concept of combinations from mathematics. A combination is a selection of items where the order does not matter. In this case, we are selecting two colors from the four available to form a pair.

To calculate the number of combinations without repetition, we can use the combination formula which is [tex]C(n, k) = \frac{n! }{ (k!(n - k)!)}[/tex], where n is the total number of items to choose from, k is the number of items to choose, and '!' represents the factorial of a number. For this scenario, n = 4 (four colors) and k = 2 (since we are forming pairs).

So, the number of combinations is C(4, 2) = [tex]\frac{4! }{2!(4 - 2)!} = \frac{4 \times 3 \times 2 \times 1 }{ 2 \times 1 \times 2 \times 1}[/tex] = 6. Therefore, there are 6 different color pairs that can be made with the colors red, blue, green, and purple.
