if John has test scores of 90 and 76 with one test remaining to be taken, what score must he make on the last test to end up with an 86 average?

Answers

Answer 1

Answer: The last score must be 92%

Step-by-step explanation: To find the average, you add all the terms, then divide by the number of terms.

86 = [tex]\frac{90 + 76 + x}{3}[/tex]258 = 90 + 76 + x (multiple both sides by 3)258 = 166 + x (combine like terms)92 = x (subtract 166 from both sides)

Find the measure of each acute angle. PLEASE HELP !!

Answers

Answer:

7x=42°

8x=48°

Step-by-step explanation:

Sum of all interior angles in a triangle=180°

90+8x+7x=180

90+15x=180

15x=180-90

15x=90

x=90/15

x=6

The measure of each acute angle is 42° and 48°.

what is an Acute angle?

If an angle is less than 90 degrees, then it is called an Acute angle. Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

Given there is a right triangle. since it's a right triangle angle one angle will always be 90 degrees.

Since the sum of all angles of any triangle is 180 degrees thus,

7x + 8x + 90 = 180

15x = 90

x  = 6

since each acute angles were 7x and 8x

hence those angles would be 42 and 48 degrees.

therefore, Each acute angle is 42° and 48° in size.

[tex]m\angle 1=95^{\circ}[/tex]

Step-by-step explanation:

If we drew an auxiliary line parallel to line [tex]p[/tex] and line [tex]q[/tex] that intersects the vertex of [tex]\angle 1[/tex], we would form three angles, one of them being

The largest of these angles corresponds with the angle marked as [tex]148^{\circ}[/tex].

The angle on the bottom right corresponds with the angle next to the one marked as [tex]63^{\circ}[/tex]. Therefore, its measure is [tex]180-63=117^{\circ}[/tex].

Since there are [tex]360^{\circ}[/tex] in a circle, we can now write the following equation:

[tex]m\angle 1+117+148=360,\\m\angle 1=\fbox{$95^{\circ}\checkmark$}[/tex].

Answer:

95

Step-by-step explanation:

The way SkiffMacKinaw did this problem is the way it should be done. There is another way of doing it by extending both arms of <1 until they intersect p and q and solve the triangle hanging from p.

You then find the the angles of the triangle. The vertex angle is the supplement to <1.

Both company 1 and 2 charge $153.75 for cleaning 25 garment

Step-by-step explanation:

Equation 1

[tex]\frac{85.50-62.75}{10-5} =\frac{22.75}{5}=4.55[/tex]

y-62.75=4.55(x-5)

y-62.75=4.55x-22.75

c(n)=4.55x + 40

Equation 2

[tex]\frac{67.50-38.75}{10-5}=\frac{28.75}{5}=5.75[/tex]

y-38.75=5.75(x-5)

y-38.75=5.75x-28.75

c(n)=5.25x + 10

The system will be

f(x)=4.55x+40

g(x)=5.75x+10

30=1.2x

x=25

f(x) when x=25

f(x)=4.55x+40

f(25)=4.55(25)+40

f(25)=113.75+40

f(25)=153.75

Let U = {q, r, s, t, u, v, w, x, y, z} A = {q, s, u, w, y} B = {q, s, y, z} C = {v, w, x, y, z}. List the elements in the set: A ∪ C Group of answer choices

Answers

Answer:

[tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex]

Step-by-step explanation:

Given: [tex]\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}[/tex], [tex]\text{A}=\left \{\text{q, s, u, w, y} \right \}[/tex], [tex]\text{B}=\left \{\text{q, s, y, z} \right \}[/tex],

[tex]\text{C}=\left \{\text{v, w, x, y, z} \right \}[/tex].

To find: The elements in the set [tex]A \cup C[/tex].

Solution:

We have,

[tex]\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}[/tex]

[tex]\text{A}=\left \{\text{q, s, u, w, y} \right \}[/tex]

[tex]\text{B}=\left \{\text{q, s, y, z} \right \}[/tex]

[tex]\text{C}=\left \{\text{v, w, x, y, z} \right \}[/tex]

Now, [tex]A \cup C[/tex] will contain all the elements in the set [tex]A[/tex] and all the elements in set [tex]C[/tex].

So, [tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex].

Hence, [tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex].

Answer: It took 13 hours by her to ride 164.45 miles.

Step-by-step explanation:

Total distance =  164.45 miles

Average distance traveled = 12.65 miles per hour  (speed)

[tex]Time = \dfrac{Distance}{Speed}[/tex]

[tex]Time = \dfrac{164.45}{12.65}=\dfrac{16445}{1265}\\\\=13\text{ hours}[/tex]

Answer:

0.2 miles

Step-by-step explanation:

From the above question:

2 miles = 10 minutes

Hence:

10 minutes = 2 miles

1 minute = x miles

Cross Multiply

10 minutes × x miles = 2 miles × 1 minute

x miles = 2 miles × 1 minute/10 minutes

x miles = 0.2 mile

The angle of the elevation from the top of a 95 Todd building into a hot air balloon in the sky and 76° if the horizontal distance between the building in a horrible Luna is 354 feet find the height of a hot air balloon

Answers

Answer:

The height of the hot air balloon is 1514.54 feet approximately.

Step-by-step explanation:

Consider the provided information.

The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon

The figure is shown below:

Let the height of the balloon is AD, the height of the building is BC.

Draw a line BE parallel to CD.

Therefore, AD=x+95, BC=95 and BE=CD=354 ft

Now in triangle [tex]ABE[/tex].

[tex]\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}[/tex]

[tex]\tan76^{\circ}=\dfrac{AE}{BE}[/tex]

[tex]AE\approx 4.01\times 354[/tex]

[tex]AE\approx 1419.54[/tex]

The height air balloon is 1419.54+95 =1514.54 ft

Hence, the height of the hot air balloon is 1514.54 feet approximately.
