The current temperature of 14°F below zero is 26°F below the high temperature of the day. What is the high temperature for the day?

Answer:

A. 4/12, C. 1/3

Step-by-step explanation:

2/6 can be divided by 3. Therefore, the fraction is 1/3.

A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.

B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.

C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.

D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.

Answer:

25 dm²

Step-by-step explanation:

La superficie de nuestra pared tiene 12.5 m²

Si dividimos la superficie por la cantidad de paneles cuadrados, obtenemos la superficie de cada panel

12.5 m² /50 = 0.25 m²

Sabemos que la superficie de un cuadrado se calcula como l²

Convertimos los 0.25 m² a dm² → 0.25 m² . 100 dm² / 1m² = 25 dm²

Esa es la medida de cada papel.

Si calculamos la medida de cada lado será:

√ (25 dm²) = 5 dm

En conclusión un cuadrado con 5 dm de lado tiene 25dm² de superficie

Si convertimos a m² = 0.25 m²

0.25 m² es la medida que cubre 1 panel de papel

para cubrir 12.5 m² necesitariamos (12.5  . 1) /0.25 = 50 paneles.

Answer:

perimeter = 10m - 5 + 6m - 2 + 8n + 4

                = 16m -7 + 8n + 4

                 16m + 8n -3

option 2

The expression represents the perimeter of the triangle will be 16m + 8n - 3. Then the correct option is B.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The sum of all the sides of the triangle will be known as the perimeter of the triangle.

A triangle has side lengths of (10m - 5) centimeters, (6m - 2) centimeters, and (8n + 4) centimeters.

The expression represents the perimeter of the triangle will be

P = (10m - 5) + (8n + 4) + (6m - 2)

P = 16m + 8n - 3

The expression represents the perimeter of the triangle will be 16m + 8n - 3. Then the correct option is B.

Answer:

x = 13

Step-by-step explanation:

This question is based on Secant Secant theorem.

Secant Secant theorem gives us the following formula:

(AB + BD)AB = (AC + CE).AC

From the above question we have the following parameters

AB = 5

BD = x

AC = 7.5

CE = 4.5

Hence,

(AB + BD)AB = (AC + CE).AC

(5 + x)5 = (7.5 + 4.5)7.5

25 + 5x = 90

Collect like terms

5x = 90 - 25

5x = 65

x = 65/5

x = 13

b)  [tex]P(9\ or\ 12)=0.3172[/tex]

c)  [tex]P(X>10)=0.51545[/tex]

Step-by-step explanation:

From the question we are told that:

Probability of Same day resolution [tex]P=70\%=>0.7[/tex]

Probability of Another day resolution [tex]Q=1-P=>30%=>0.3[/tex]

Sample size [tex]n=15[/tex]

a)

Generally the equation for Probability 10 of the problems can be resolved today is mathematically given by

Since

 [tex]P(X)=^{n}C_{x}*p^{x}*Q^{n-x}[/tex]

 [tex]P(10)=^{15}C_{10}*p^{10}*Q^{15-10}[/tex]

 [tex]P(10)=\frac{15!}{10!(15-10)!*0.70^{10}*0.30^5}[/tex]

 [tex]P(10)=0.2061[/tex]

b)

Generally the equation for Probability 9 or 12 of the problems can be resolved today is mathematically given by

 [tex]P(9)=\frac{15!}{9!(15-9)!*0.70^{9}*0.30^6}[/tex]

 [tex]P(9)=5005*2.942*10^{-5}[/tex]

 [tex]P(9)=0.1472[/tex]

OR

 [tex]P(12)=\frac{15!}{12!(15-12)!*0.70^{12}*0.30^3}[/tex]

 [tex]P(12)=455*3.737*10^{-4}[/tex]

 [tex]P(12)=0.17[/tex]

Therefore Probability 9 or 12 of the problems can be resolved today is

 [tex]P(9\ or\ 12)=P(9)+P(12)[/tex]

 [tex]P(9\ or\ 12)=0.1472+0.17[/tex]

 [tex]P(9\ or\ 12)=0.3172[/tex]

c)Generally the equation for probability more than 10 of the problems can be resolved today is mathematically given by

 [tex]P(X>10)=P(11)+P(12)+P(13)+P(15)[/tex]

Where

 [tex]P(11)=\frac{15!}{11!(15-11)!*0.70^{11}*0.30^4}[/tex]

 [tex]P(11)=0.2186[/tex]

 [tex]P(13)=\frac{15!}{13!(15-13)!*0.70^{13}*0.30^2}[/tex]

 [tex]P(13)=0.0916[/tex]

 [tex]P(14)=\frac{15!}{14!(15-14)!*0.70^{14}*0.30^1}[/tex]

 [tex]P(14)=0.0305[/tex]

 [tex]P(15)=\frac{15!}{15!(15-15)!*0.70^{15}*0.30^0}[/tex]

 [tex]P(15)=0.00475[/tex]

Therefore

 [tex]P(X>10)=0.2186+0.0916+0.0305+0.00475+0.17[/tex]

 [tex]P(X>10)=0.51545[/tex]

Answer:

44.44°

Step-by-step explanation:

A tower that is 101 feet tall casts a shadow 103 feet long. Find the angle of elevation of the sun to the nearest degree.

We solve this question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = ?

Opposite = Height of the tower = 101 feet

Adjacent = Length of the shadow = 103 feet

Hence

tan θ = 101/103

θ = arc tan (101/103

θ = arctan(0.9805825242718447)

θ = 44.438294667°

Approximately to the nearest degree = Angle of elevation = 44.44°

Answer: 4 bags

Step-by-step explanation:

2 cups  =  16 ounces

So  using a proportion

16 / 8   =  x  /  60          where  x  is the number of ounces we need to buy

cross-multiply

16 * 60   =  8 * x

960   = 8 x

960 / 8   = x  =   120    ounces

The  number of  bags  we  need   =    ceiling  [ 120/32 ]    = 4 bags

Answer:

B. 3

Step-by-step explanation:

============================================================

Explanation:

Angles 1 and 3 are vertical angles. Note how line t and line r intersect to form an X shape. Angle 1 and angle 3 are opposite angles in this X configuration, which is what makes them vertical angles. Vertical angles are always congruent.

Angle 1 is congruent to angle 2 if and only if both angles were 90 degrees (note the angles are supplementary). Otherwise, they aren't congruent. That allows us to rule out choice A. Choice C is ruled out for the exact same reason.

Answer:

x = 30

Step-by-step explanation:

correct me if i am wrong but i think you have to

a.) change the denominator's to be the same :

ten is a common denominator therefore you times the second expression by two ( x/5 becomes 2x/10 )

b.) put the formula back together :

3x/10 + 2x/10 = 15

5x/10 = 15

5x = 150

x = 30

Answer:

y = 5x -23

Step-by-step explanation:

Alright, for this, we need the slope and the y intercept. First, the slope.

So to find the slope, find any two points that the line goes over first. For example, the dotted point (5,2). Now for the other one, (4,-3) can be used.

Look for when the line is crossing over the points of the square graph, as this will help you with the next part.

For the next part, to find the slope, this is going to see how much the line has done up/down for how much we move forward or backwards on the line. With this, the equation:

y2-y1 / x2-x1 can be used, with the 2s and 1s being just to show that there are 2 separate points being used for it.

Next, plug it in with what's known:

2-(-3) / 5-4

5 / -1

Slope is 5.

Now, the y intercept needs to be found. To get this, we need the y value for where the line passes over where the x value is 0.

By knowing that the slope is 5, we can walk backwards to the y intercept to get this value. With this, for every number in x walked back, it will go down 5 y values:

5, 2 (Do -1, -5)

4, -3 (Do -1, -5)

3, -8 (Do -1,-5)

2, -13 (Do -1,-5)

1, -18 (Do -1,-5)

0, -23 (All done)

The y intercept is now found, along with the slope. Now these values can be both be plugged into the slope intercept equation, y=mx+b, where m is for the slope and b is where the y intercept goes.

y = 5x -23
