omg please help its due by 12 am! the sum of 2 numbers is 69. the larger number is 3 less than twice the smaller number .find the numbers. show your work!
Answer:
x = 45, y = 24.
Step-by-step explanation:
If the 2 numbers are x and y:
x + y = 69...........(1)
x = 2y - 3
x - 2y = -3...........(2)
Subtract: (1) - (2):
x - x + y - (-2y) = 69 - (-3)
y + 2y = 72
3y = 72
y = 24.
From equation 1:-
x + 24 = 69
x = 45.
Answer:
one number would be 63 and the other would be 6
Step-by-step explanation:
69/2=34.5
it says 3 less which means minus 3, so you would:
34.5-3=31.5
then it says twice the smaller number, so you would:
31.5*2
there are 3 numbers in ascending order such that the difference of first two is 10 and that of last two is 12. if the sum of three numbers is 47, find the least number.
Answer:
17/3
Step-by-step explanation:
x + y + z = 47
y - x = 10 x = y - 10
z - y = 10 z = 10 + y
y-10 + y + 10 + y = 47
3 y = 47
y = 47/3 x = 17/3 z = 77/3

A spherical balloon has a circumference of 25 cm.
a.) What is the approximate surface area of the balloon to the nearest square centimeter?
b.) What is the approximate volume of the balloon to the nearest cubic centimeter?
The approximate surface area of the balloon is 199 cm².
The approximate volume of the balloon is 262 cm³
What is the surface area and the volume of the balloon?Radius of the balloon = circumference / 6.2832
25 / 6.2832 = 3.98cm
Surface area = 4πr²
4 x 22/7 x 3.97² = 199 cm²
Volume = 4/3πr³
4/3 x 22/7 x 3.97³ = 262.20 cm³

A bird drops a stick to the ground from a height of 75 ft. The function h= - 16t2 + 75 gives the stick's
approximate height h above the ground, in feet, after t seconds. Graph the function. At about what time does the stick hit the ground?
graph.
The function h(t) = -16t^2 + 75 is a quadratic function, and the stick hits the ground at about 2.165 seconds
How to determine the time it hits the ground?The function is given as:
h(t) = -16t^2 + 75
Next, we plot the graph of the function h(t)
From the graph of the function h(t) (see attachment), we have the following highlight:
t = -2.165 and t = 2.165 when h(t) = 0
Time cannot be negative.
So, we have:
t = 2.165
This means that the stick hits the ground at about 2.165 seconds

What is the maximum volume of a square pyramid that can fit inside a cube with a side length of 14 cm?
Answer:
Step-by-step explanation:
Pyramid height should be 14
Base area should be 14*14(196)
So, Base area is 196
1. Multiply the Base area by the height of the pyramid:
196*14=2744
2. Divide the number above by 3:
2744/3=914.7
Does the budgeted amount cover the actual amount for expenses, savings, and emergencies? a) no, it's short $207.00. b) no, it's short $227.00. c) yes, there's a surplus of $207.00. d) yes, there's a surplus of $227.00.
The expense amount is more than the savings amount. No, it's short $207 then the correct option is A.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.
From the table, we have
The amount of the savings will be
Saving amount = $ 20
Then the amount of the expense will be
Expense amount = 150 + 75 + 2 = 227
Then the budgeted amount covers the actual amount for expenses, savings, and emergencies will be
→ savings amount - expense amount
→ 20 - 227
→ $ 207
Thus, the expense amount is more than the savings amount. No, it's short $207.

Volume of water in Tank A
7 x 7 x 7343 cm³Volume of Tank B
15 x 14 x 10210 x 102100 cm³Finding Height
Volume of water of Tank A filled in Tank B / Base Area of Tank B343 / 2101.63 cmAnswer:
1.63 cm (nearest hundredth)
Step-by-step explanation:
Formulae
Volume of a cuboid = base width × base length × height
Area of a rectangle = width × length
Tank A
Given:
base width = 7 cmbase length = 7 cmheight = 7 cm⇒ Volume of Tank A = 7 × 7 × 7 = 343 cm³
Tank B
⇒ Base area of Tank B = 14 × 15 = 210 cm²
Solution
Height = volume of Tank A ÷ base area of Tank B
= 343 ÷ 210
= 49/30 cm
= 1.63 cm (nearest hundredth)
The cyclist drove from the village to the town, 30 km away. back on
the same road, he reduced his speed to 2 km/h and therefore
drove 30 minutes longer. At what speed did the cyclist ride from
the village to the city?
Please I really need your help quick
Answer:
14.5 hours
Step-by-step explanation:
Take the return trip situation.
From town to village
Distance = 30 kmSpeed = 2 km/hTime = Distance/Speed = 15 hoursThat is equal to the sum of t, the time taken from the village to the city and 30 minutes.
⇒ t + 30 minutes = 15 hours
⇒ t + 0.5 hours = 15 hours
⇒ t = 14.5 hours

Answer:
c= 30
Step-by-step explanation:
To find the value of c, start by forming an equation using the ∠ sum of ∆ property.
c° +60° +90°= 180° (∠ sum of ∆)
Simplify:
c° + 150°= 180°
c°= 180° -150°
c°= 30°
c= 30
Notes:
The sum of the angles in a triangle is 180°, which is abbreviated as '∠ sum of ∆'. The angle indicated by a square is called a right angle, and has a value of 90°.

What is Quadrilateral?A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles
A trapezoid is a quadrilateral with one pair of opposite sides parallel.
ABCD is a trapezoid.
We have to find the value of x in the given quadrilateral.
The sum of opposite angles of a quadrilateral is 180 degrees.
m(∠B)+m(∠D)=180°
From the figure m(∠B) is 3x and m(∠D) is 9x
3x+9x=180°
Combine the like terms
12x=180
x=15 degrees.
Hence, the value of x is 15 degree in the trapezoid ABCD.
