and 20
Right angled triangle ✅
90° + 3x + 2x = 180° {sum}
5x = 90
x = 90/5 = 18
x = 18
acute angle : 3x = 3 × 18 = 54°
2x = 2 × 18 = 36°

1000cm in the ratio of 4:5:6
Step-by-step explanation:
4+5+6=1000
1000/15
4 . 5. 6= 266.4 . 333. 399
9514 1404 393
Answer:
266 2/3 : 333 1/3 : 400
Step-by-step explanation:
The total of ratio units is 4+5+6 = 15, so the fraction of 1000 that each portion represents is ...
4/15 : 5/15 : 6/15 = 4/15 : 1/3 : 2/5
Multiplying 1000 by these fractions gives ...
1000(4/15) : 1000/3 : 1000(2/5)
= 266 2/3 : 333 1/3 : 400

cos(6x-12) = sin(8x-10)
Subtract sin (8x − 10) from both sides of the equation.
cos (6x − 12) − sin (8x − 10) = 0
Answer:
It doesn't exist
Step-by-step explanation:
since :
cos (90° – x) = sin x
cos(x) = sin(pi/2 - x)
then
cos(6x-12) =! sin(8x-10)
since (8x-10) =! (pi/2- 6+12)
then this identity of cos(6x-12) = sin(8x-10) doesn't exist

Step-by-step explanation:
Peter has $12 in nickels and quarters. Altogether, he has 72 coins. Use the variables n and q to write and solve a system of equations to determine how many of each coin she has.
Step-by-step explanation:
n= nickels
q= quarters
Create a system of equations
n + q =72 number of coins
0.05n + 0.25q = 12 amount in money
solve by elimination ( anything would be fine)
n + q = 72
4( 0.05n + 0.25q = 12)
n+ q = 72
-
0.2n + q = 48
0.8n = 24
n= 30
now use substitution to find how many quarters she has
30 + q = 72
q = 42
He has 30 nickels and 42 quarters
Sorry for skipping some steps

5
-5
Answer:
10
Step-by-step explanation:
Range of data = Highest value - Lowest value
Here,
Highest value = 5
Lowest value = -5
Range = 5 - (-5)
= 5 + 5
= 10
Ms. Emily buys a hat and gloves with a coupon for 30% off her entire purchase. The glove cost $35 before the discount. Her bill before tax is 44.80
Answer:
Step-by-step explanation:
Okay, I'm assuming you want us to figure out how much the hat costs.
To start off, let's figure out how much the gloves cost after the discount. 35 / 100= 0.3. We multiply that by 70%, since that is how much of the price is going to be left over after deducting 30%. We get $24.50.
So;
$44.80 of the total bill - $24.50=$20.30.
So we now know the hat cost $20.30.

Select the FALSE statement
A) Dilations either increase or decrease the lengths of line segments.
B) Dilations increase angle measures.
C) A dilated triangle is similar to the original triangle.
D) Dilations are a type of transformation
9514 1404 393
Answer:
B) Dilations increase angle measures.
Step-by-step explanation:
Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.
The false statement is B.

Andre and Elena are each saving money Andre starts with $100 in his savings account and adds five dollars per week Elena starts with $10 in her savings account and add 20 each week after four weeks who has more money in her savings account
Answer: Andre
Step-by-step explanation: coz I juss know..
Answer:
Andre
Step-by-step explanation:
This situation can be modeled with the equations:
A = 100 + 5w
E = 10 + 20w
Let w represent the number of weeks that have passed since they have started saving money. Andre(A) has saved $5 per week and Elena(E) has saved $20 per week. Substituting 4 into the equation (because 4 is the number of weeks that have passed so far) and evaluating we come to the realization that Andre still has more money than Elena because he now has $120 and Elena has $90.

I need help with this one can someone tell me??
Answer:
x=22 y= 46
Step-by-step explanation:
2-24 2-48
Answer:
Equations are :---
[tex]3x - 2y = 24............... (i) \\ x + 2y = 48..................(ii)[/tex]
By adding the both equations we get,
[tex](3x - 2y) + (x + 2y) = 24 + 48 \\ 4x = 72 \\ x = \frac{72}{4} \\ \boxed{ x = 18} \\ [/tex]
Putting the value of x in equation (ii) we get
[tex]18 + 2y = 48 \\ 2y = 48 - 18 \\ 2y = 30 \\ y = \frac{30}{2} \\ \boxed{y = 15}[/tex]
Therefore, x=18 and y=15 is the right answer.A shirt is on sale for 1 the original cost, what would be an equivalent decimal and

if you put money into a savings account that earns $84.00 over seven years at a rte of 3%, how much money did you put into the account?
Answer:
Step-by-step explanation:
To solve this, we would use the formula for calculating simple interest which is:
Interest = PRT
Then, we will slot in the values given which will be:
84 = P × 3% × 7
84 = P × 0.03 × 7
84 = 0.21P
P = 84/0.21
P = $400
The Principal is $400
