Answer:
y=5
x=30
Step-by-step explanation:
the triangle with all congruent angles is an equilateral triangle, which means all side and angles are congruent, so 8y has to equal to 40 by dividing 40 by 8.
x and the angle about forms a complementary angle, so it has to be 30 degrees to add up to 90.

Since the bank gave them a credit to withdraw money to pay for the play. And the play was 3,200.00. The credit is on -3,200.00.
Since each ticket is $10.00 and 1,007 ppl attended. You multiply them together
1,007 x 10 = 10,070.
Since you depositing it to the credit card the -3,200.00 will ver deducted from the 10,070.00 that you put in. So you subtract.
$10,070.00 - $3,200.00 = $6,870.00.

Answer:
8 bulbs
Step-by-step explanation:
In the model, each + represents a dollar
4 +s for the shipping cost, 20 +s for the total cost.
Therefore we have 2x (since each bulb is $2) + 4 = 20
2x = 16
x = 8
Step-by-step explanation:
x is the number of bulbs.
We have $2x + $4 = $20.
=> $2x = $16, x = 8.
Hence Sheila can order 8 flower bulbs.
Michela’s skateboard ramp is at an incline of 40°. When she attempts a trick on the ramp, she finds that it is too steep. She adjusts the ramp to half of the original incline. What is the measurement of the incline now?
Answers
Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original incline
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees

A hair stylist offers haircuts and hair coloring to his customers. A haircut costs $18 and hair coloring costs $42. Yesterday, the hair stylist had 12 customers and earned a total of $288. How many of the hair stylists customers received hair coloring yesterday
Answers
Answer:
haircut =9 and hair color= 3
Step-by-step explanation:
Step one:
GIven data
let the haircut be x
and hair color be y in numbers.
so
18x+42y=288------------1
x+y=12---------------------2
from 1
x=12-y, put this in 2, we have
18(12-y)+42y=288
216-18y+42y=288
collect like terms
24y=288-216
24y=72
divide both sides by 24
y=72/24
y=3
put y= 3 in 2
x+3= 12
x= 12-3
x=9

(8x+12)
(3x-8)
Answers
Answer:
x = 16, y = 140
Step-by-step explanation:
(8x + 12)° and (3x - 8) are adjacent angles and are supplementary, sum to 180°
8x + 12 + 3x - 8 = 180
11x + 4 = 180 ( subtract 4 from both sides )
11x = 176 ( divide both sides by 11 )
x = 16
Then
8x + 12 = 8(16) + 12 = 128 + 12 = 140
(8x + 12) and y are alternate angles and are congruent , so
y = 140

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The hypotanenuse is 5 cm
The angle opposite to right angle is 45 degrees.
As it is a right angle one angle is 90 degrees.
This is a right angled isosceles triangle whose sides are in the ratio 1:1:√2.
In an isosceles right triangle, the equal sides make the right angle. They have the ratio of equality, 1 : 1.
So 5/√2.
Multiply numerator and denominator by √2
We get 5√2/2
Hence, 5√2/2 is the value of x in the triangle.

O A box contains 40 oranges, 12 of which are
unripe. I pick one at random.
What is the probability that it is
a ripe
b unripe?
Answers
Step-by-step explanation:
Nø of sample space, n(s) = 40
nø of unripe oranges, n (u) = 12
no of ripe oranges, n (r) = 40 - 12 = 28
Now
The probability that it is ripe is, P(E)
= n(r) / n(s)
= 28 / 40
= 7 / 10
Also the probability that it is unripe is, P(E)
= n(u) / n(s)
= 12 / 40
= 3 / 10

2.5m to 150 cm
express these ratios in its simplest form.
Answers
Answer:
The ratios in the simplest form is 5:3
Step-by-step explanation:
Given that:
2.5m to 150cm
We have to express these ratios in simplest form but we will convert the quantities into same unit first.
Therefore,
Converting meters into centimeters
1 meter = 100 cm
2.5 m = 100*2.5 = 250 cm
Ratio form;
250 cm : 150 cm
As both the number are multiples of 50,
[tex]\frac{250}{50}:\frac{150}{50}\\5:3[/tex]
Hence,
The ratios in the simplest form is 5:3
if perimeter and length of a rectanguar field are 154m and 42m respectively, find its breadth
Answers
Answer:
Assuming you mean width not breadth (What is that)
The width would be: 35m
Step-by-step explanation:
Now its pretty staight forward
We know that the length is 42m
And the permineter is 154m
We know that the perimeter is the 2 widths and 2 lengths all added up to each other (basically very side added up)
An eaution could be used like, 2w+2l=154
We know length is 42 so
2w+2*42=154
Now just solve for W
2*42=84
2w+84=154
154-84= 70
70=2w
70/2=35
w=35
