Answer:
x = -5
Step-by-step explanation:
Angles "50" and "x+55" are alternate interior angles which means that they are the same.
So 50 = x + 55
That leaves you with x = -5

A recipe uses cups of milk to make servings. If the same amount of milk is used for each serving, how many servings can be made using gallon of milk?
Answers
Answer:
128 servings
Step-by-step explanation:
A recipe Uses 1 1/4 cups of milk to make 10 servings if the same amount of milk is used for each serving how many servings can be made using one gallon of milk
Cups of milk : number of servings = 1 1/4 cups : 10 servings
One gallon of milk = 16 cups
Let x = number of servings
Cups of milk : number of servings = 16 cups : x
Equate both ratios
1 1/4 : 10 = 16 : x
5/4 ÷ 10 = 16/x
5/4 × 1/10 = 16/x
5/40 = 16/x
1/8 = 16/x
Cross product
1 * x = 8 * 16
x = 128 servings
Number of servings = 128
A sphere and a cone have the same volume. The sphere has a radius x and height y. The cone has a radius of 1/2x. Find the height of the cone in terms of y.
Answers
Answer:
h = 16x
Step-by-step explanation:
The volume of a sphere and a cone is same such that,
[tex]V_s=V_c\\\\\dfrac{4}{3}\pi r^3=\dfrac{1}{3}\pi R^2h[/tex]
We have, r = x, R = (1/2)x, h= ? (height of the cone)
So,
[tex]\dfrac{4}{3}\pi x^3=\dfrac{1}{3}\pi (\dfrac{x}{2})^2h\\\\4x^3=\dfrac{x^2}{4}h\\\\h=\dfrac{16x^3}{x^2}\\\\h=16x[/tex]
So, the height of the cone is equal to 16x.

It cost $5 to send 6 packages through a certain shipping company. Consider the number of packages per dollar. Find the constant of proportionality for this situation. ENTER ONLY A NUMERICAL ANSWER. NO WORDS, SYMBOLS, OR ADDITIONAL SPACES
Answers
Answer:
1.2 packages per dollar
Step-by-step explanation:
Number of packages = 6
Total cost in dollars = $5
Number of packages per dollars = Number of packages / Total cost in dollars
= 1.2 packages per dollar
Let
P = number of packages
d = cost in dollars
k = constant of proportionality
P = k * d
6 = k * 5
k = 6/5
k = 1.2
Constant of proportionality = 1.2

There are eight boys and six girls who are members of the trumpet section in the band. From the members of the trumpet section, a quintet is being formed. If the quintet must consist of three boys and two girls, how many quintets are possible?
Answers
Answer:
8 c 3 * 6 c 2 = 56 * 15 = 840 ways
Step-by-step explanation:
First, we consider how many ways there are to choose three boys from eight. There are 8 choices for the first boy, 7 for the second, and 6 for the third. However, because the boys are indistinct from one another, we have overcounted, and must divide by 3*2. Similarly, there are 6*5 ways to choose the two girls, divided by 2 for overcounting. Thus, there are (8*7*6*6*5)/(3*2*2)=840 possible quintets.

*see attachment for the figure
Answer:
Side BC = 3.0 millimeters, Angle A = 66.6 degrees, Side AC = 1.3 millimeters
Step-by-step explanation:
Given:
C = 90°
B = 23.4°
AB = c = 3.3 mm
Required:
<A, BC, and AC
Solution:
✔️m<A = 180° - (90° + 23.4°) (sum of triangle)
m<A = 66.6°
✔️To find BC and AC, apply trigonometric function:
Reference angle = 23.4°
Hypotenuse = 3.3 mm
Opposite = AC
Adjacent = BC
✅Apply CAH to find AC:
Cos 23.4 = Adj/Hyp
Cos 23.4 = BC/3.3
3.3 × Cos 23.4 = BC
3.02859027 = BC
BC ≈ 3.0 mm
✅Apply SOH to find AC:
Sin 23.4 = Opp/Hyp
Sin 23.4 = AC/3.3
3.3 × Sin 23.4 = AC
1.31058804 = AC
AC ≈ 1.3 mm
Answer: B bc=3.0mm, A=66.6, AC=1.3mm

Looking up, Josh sees two hot air balloons in the sky as shown. He determines that the lower hot air balloon is 700 meters away, at an angle of 38 from the vertical. The higher hot air balloon is 1050 meters away, at an angle of 26 from the vertical. How much higher is the balloon on the right than the balloon on the left? Do not round any intermediate computations. Round your answer to the nearest tenth.
Answers
Answer:
In right angled triangle ABC
tan 26=perpendicular/base
tan26 =BC/1050
BC=1050×tan26=512.12m
again
In right angled triangle ADE
tan 38=perpendicular/base
tan38×700=DE
DE=546.9=547m
now
difference in height =547-512.12m=34.8m=35m
35 m is your answer
Josh sees two hot air balloons in the sky as shown. 35m higher is the balloon on the right than the balloon on the left.
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
Josh sees two hot air balloons in the sky as shown.
He determines that the lower hot air balloon is 700 meters away, at an angle of 38 from the vertical.
The higher hot air balloon is 1050 meters away, at an angle of 26 from the vertical.
In right-angled triangle ABC
tan Ф = perpendicular/base
tan26 = BC/1050
BC = 1050 × tan26
BC = 512.12m
In right-angled triangle ADE
tan Ф = perpendicular/base
tan 38 = perpendicular/base
tan38 × 700 = DE
DE = 546.9
DE = 547m
The difference in height = 547 - 512.12m
=34.8m
= 35m
Therefore, 35m higher is the balloon on the right than the balloon on the left.

Answer:
y = 2x + 3
Step-by-step explanation:
We need to find m and b
Let's input the first 2 points (3, 9) and (5, 13) into y = mx + b
9 = m*3 + b
13 = m*5 + b
subtract the first from the second
13 - 9 = m*5 + b - (m*3 + b)
4 = m*2
m = 2
Now let's input m = 2 into 9 = m*3 + b
9 = 2*3 + b
9 = 6 + b
3 = b
So the final relationship is y = 2x + 3
We can verify that the other two points (8, 19) and (11, 25) also conform to this relationship.
