Answer:
104.6 deg, 75.4 deg
Step-by-step explanation:
One angle measures x.
The other angle measures 29.2 deg less than x, so it measures x - 29.2.
They are supplementary angles, so the sum of their measures is 180 deg.
x + x - 29.2 = 180
2x - 29.2 = 180
2x = 209.2
x = 104.6
x - 29.2 = 75.4
Answer: 104.6 deg, 75.4 deg
In how many different ways can four students stand in a straight line if two of the students refuse to stand next to each other?
Hey there! I'm happy to help!
Let's look at each spot in the line from left to right and see how many choices they are.
In spot 1, we have 4 choices. Let's say that we choose the student who doesn't want to stand next to to the other student. This means that in the next slot, there are only 2 choices because he cannot stand by the other student. Now when we move to spot number three, there are only two choices left, and then there is 1.
4×2×2×1=16
So, there are 16 different ways the students can stand in a straight line if two of the students refuse to stand next to each other.
Have a wonderful day! :D

A drama club made $3,200 from a school play. Seventy-five percent of that amount came from ticket sales. Identify the values of the variables in the model. Then use the model to find the amount of ticket sales.
a =
b =
The amount of ticket sales is $
.
Answer: $2400
Step-by-step explanation:
Based on the question above, a will be the percentage of tickets that were sold while b will be tickwt sales. Therefore,
a = 75%
b = 75% × $3,200
= 0.75 × $3200.
= $2400
Based on the information above, the amount of tickets sales is $2400

The formula of a circumference of a circle with radius r:
[tex]C=2\pi r[/tex]
Solve for r:
[tex]2\pi r=C[/tex] subtitute [tex]\pi\approx\dfrac{22}{7}[/tex]
[tex]2\cdot\dfrac{22}{7}r=C[/tex]
[tex]\dfrac{44}{7}r=C[/tex] multiply both sides by 7
[tex]44r=7C[/tex] divide both sides by 44
[tex]r=\dfrac{7C}{44}[/tex]

Find three consecutive even integers such that the sum of the second and third is 3 times the first integer.
Answer:
3, 4, and 5
Step-by-step explanation:
Given: We're looking for x, x+1, and x+2
Requirements: (x+1)+(x+2)=3(x)
Solve equation:
x+1+x+2=3x
2x+3=3x
3=x
This means the three consecutive integers are 3, 3+1, and 3+2 which is the same as 3, 4, and 5

The perimeter of a circular garden is 440m. A path 1.4m runs inside the park. find the cost of gravelling the path at the rate of Rs.100 per square meter.
Answer:
Cost = Rs. 6095.95
Step-by-step explanation:
We are given the perimeter as 440m.
Mow,perimeter of a circle is also called circumference.
Formula for circumference of a circle is;
C = 2πR
Thus:
2πR = 440
R = 440/2π
R = 70 m
We are told that A path 1.4m runs inside the park. Thus radius of smaller circle: r = 70 - 1.4 = 68.6 m
Area of larger circle: A1 = πR² = π(70²)
A1 = 4900π
Area of smaller circle: A2 = πr² = π(68.6²)
A2 = 4705.96π
Area of path = A1 - A2
Area of path = 4900π - 4705.96π
Area of path = 194.04π Sq.m
We want to find the cost of gravelling the path at the rate of Rs.100 per square meter.
Thus;
Cost = 100 × 194.04π
Cost = Rs. 6095.95

A computer normally sells for $520. During a sale, the computer is
discounted 15% off. How much will it cost to buy the computer during the
sale? (Sale Price)
Answer:
$442
Step-by-step explanation:
Multiply the sales price by the discount percentage. This is the total discount that was taken off.
$520 x 15% = $78.
Subtract the discount amount from the sales price. This gives you the amount that the computer costs after the discount.
$520 - $78 = $442
The computer costs $442.

Aisha is a cyclist. She rode 3 ¾ miles in ⅓ hours. A. How fast was she going in miles per hour?
Answer:
11 1/4 miles per hour
Step-by-step explanation:
Put the mixed number in improper form to make it easier. You get 15/4 miles in 1/3 hours. You want the miles for 1 hour. So you multiply 15/4 miles by 3 to get 45/4 miles, or 11 1/4 miles per hour

Answer:
Marion is 24, Judy is 12
Step-by-step explanation:
Let j represent Judy's age now. 6 year ago, the relation was ...
3(j -6) = (2j) -6
3j -18 = 2j -6 . . . . . eliminate parentheses
j = 12 . . . . . . . . . . . add 18-2j
2j = 24 . . . . . . . . . Marion's age now
Judy is 12; Marion is 24.
In ΔPQR, \overline{PR} PR is extended through point R to point S, \text{m}\angle QRS = (4x-15)^{\circ}m∠QRS=(4x−15) ∘ , \text{m}\angle RPQ = (x+1)^{\circ}m∠RPQ=(x+1) ∘ , and \text{m}\angle PQR = (x-2)^{\circ}m∠PQR=(x−2) ∘ . Find \text{m}\angle RPQ.m∠RPQ.
Answer:
Step-by-step explanation:
Notice that, the angle QRS is external to the triangle and adjacent to the angle PRQ. According to the theorem of a external/adjacent angle, we have: m∠QRS = m∠PQR + m∠RPQ, where PQR and RPQ are internal angles.
From the hypothesis, we have:
m∠QRS =(10x−12)∘(10x−12)
m∠PQR = (3x+20)∘(3x+20)
m∠RPQ=(3x−8)∘(3x−8)
Using the first equation and replacing the hypothesis:
m∠QRS = m∠PQR + m∠RPQ
(10x−12)∘(10x−12) = (3x+20)∘(3x+20) + (3x−8)∘(3x−8)
Multiplying and applying the remarkable identity:
Then, we use a calculator to find the roots, which are:
In this case, we will see what root is the right one.
Now, we replace it into m∠QRS =(10x−12)∘(10x−12), because we need to find m∠QRS.
m∠QRS =(10x−12)∘(10x−12) = (10(4.7) - 12) (10(4.7) - 12) = (35) (35) = 1225

In the figure, if m ZABD = 120°, then mZADC =
0.
Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,
[tex]\frac{\text{sin}(\angle ABD)}{\text{AD}}=\frac{\text{sin}(\angle ADB)}{AB}[/tex]
[tex]\frac{\text{sin}(120)}{35}=\frac{\text{sin}(\angle ADB)}{30}[/tex]
sin(∠ADB) = [tex]\frac{30\text{sin}(120)}{35}[/tex]
= 0.74231
m∠ADB = [tex]\text{sin}^{-1}(0.74231)[/tex]
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°
