The greater of two numbers is 3 times the smaller.
Their sum is 44. Find the numbers.
Answers
Answer:
11 and 33
Step-by-step explanation:
The greater of two numbers is 3 times the smaller.
Let the numbers be
n and 3n
sum is 44
n + 3n = 44
4n = 44
Divide both sides by 4
n = 11
3n = 3 * 11
3n = 33
Answer:
smaller number is 11
bigger number is 33.
Step-by-step explanation:
Lets make the smaller number be a, the bigger number 3a since its 3 times a's value
the sum of a and 3a is 44
so we write
a+3a = 44
combine like terms
a+3a = 4a
4a = 44
divide both sides by 4
a = 11.
Now we know the smaller number is equal to 11, but we are not done just yet.
We have to find the value of the bigger number by plugging in 11 into our equation
11+3*11 = 44
11 + 33 = 44
which means the bigger number is 33
Question 9 of 10 Based only on the given information, it is guaranteed that AB I CD. A D . Given: AABC ZDAC = ZDBC O A. True O B. False

Answer:
False
Step-by-step explanation:
False
There is not enough information to guarantee the lines are perpendicular.
No, we can not say that AB and CD are perpendicular from the information given.
What are perpendicular line?Two geometric objects are perpendicular if their intersection forms right angles at the point of intersection called a foot.
The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂.
Given that a triangle ABC, divided into two triangles by a line DC, also
angle DAC and DBC are congruent,
From the given information we can not conclude any relation between both triangles,
Hence, we can not say that AB ⊥ CD

Answer:
The car price decreased by $2,268.
The price of the car now is $33,732.
Step-by-step explanation:
Multiply 0.063 (6.3% in decimal form) by $36,000 to get $2,268, which is how much the price decreased.
Then subtract 2,268 from 36,000 to get $33,73, which is the price of the car after the decrease.
Answer:
Step-by-step explanation:
6.3 : 100 = x : 36000
x = (36000 * 6.3)/100 = $2268 (decrease in price)
Price of new model: 36000 - 2268 = $33732

*She begins at sea level, which is an elevation of 0 feet.
*She descends for 91 seconds at a speed of 2.2 feet per second.
*She then ascends for 32 seconds at a speed of 0.7 feet per second.
At this point, what is her elevation, in feet?
if you anserw corectly ill give you crown and more points
Answers
Answer:
-177.8 feet below sea level.
Step-by-step explanation:
First, we know that decend means to lower. Anything lower than 0 has to be negative. It says that she decends for 91 seconds at a speed of 2.2 feet per second. So first to find out how many feet she descended in those 91 seconds, you need to multiply 91*-2.2= -200.2. Then, it says that she ascends for 32 seconds at the speed of 0.7 feet per second. It's the same thing, but ascend means to go up. So, we multiply 32*0.7=22.4. Now we add the two numbers together to get -177.8.

The ice cream cone has a radius of 3 cm and a height of 10 cm. If the scoop of ice cream is a sphere with radius of 3.5 cm, will all of the ice cream fit inside the cone?
Answers
Answer:
No, ice cream cannot fits inside the cone.
Step-by-step explanation:
radius of cone, r = 3 cm
height of cone, h = 10 cm
radius of ice cream sphere, R = 33.5 cm
The volume of the cone is
[tex]V =\frac {1}{3}\times \pi\times r^{2}\times h\\\\V = \frac{1}{3}\times 3.14\times 3\times 3\times 10\\\\V =94.2cc[/tex]
Volume of ice cream
[tex]V' =\frac{4}{3}\pi\times r^{3}\\\\V'= \frac{4}{3}\times 3.14\times 3.5^{3}\\\\V' = 179.5cc[/tex]
As the volume of ice cream is more than the volume of cone, so it cannot fit into the cone.

Answers
Answer:
Volume of cone = 33.49 inch³
Step-by-step explanation:
Missing information;
Height of cone = 8 inch
Diameter of cone = 4 inch
Find:
Volume of cone
Computation:
Radius of cone = Diameter of cone / 2
Radius of cone = 4 / 2
Radius of cone = 2 inch
Volume of cone = [1/3][πr²h]
Volume of cone = [1/3][(3.14)(2)²8]
Volume of cone = [1/3][(3.14)(4)8]
Volume of cone = [1/3][(3.14)(32)]
Volume of cone = [1/3][100.48]
Volume of cone = 33.49 inch³
Kim buys a carpet for a room. The carpet measures 6 metres by 6 metres. Kim pays £390 for the carpet. The room measures 5 metres by 5 metres. Work out the cost of the carpet she does not use.
Answers
Area = Length x width
Area of carpet = 6 x 6 = 36 square meters
Cost of carpet per square meter = total cost / area
Cost per square meter: 390 / 36 = £10.83
Area of room = 5 x 5 = 25 square meters.
Area of rug not used = area of room subtracted from area of carpet:
36 - 25 = 11 square meters
Cost of the carpet not used = area of carpet not used x cost per square meter
11 x 10.83 = 119.13
ANSWER: £119.13
Answer:
Area = Length x width
Area of carpet = 6 x 6 = 36 square meters
Cost of carpet per square meter = total cost / area
Cost per square meter: 390 / 36 = £10.83
Area of room = 5 x 5 = 25 square meters.
Area of rug not used = area of room subtracted from area of carpet:
36 - 25 = 11 square meters
Cost of the carpet not used = area of carpet not used x cost per square meter
11 x 10.83 = 119.13

(5.-2) and (-1, -1)
Answers
Answer:
Step-by-step explanation:
Use the formula of distance between two points (x₁, y₁) and (x₂, y₂),
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
1). Distance between (4, 1) and (2, 2) = [tex]\sqrt{(4-2)^2+(1-2)^2}[/tex]
= [tex]\sqrt{5}[/tex]
= 2.24
2). Distance between (-5, 2) and (-3, -2) = [tex]\sqrt{(-5+3)^2+(2+2)^2}[/tex]
= [tex]\sqrt{20}[/tex]
= 4.47
3). Distance between (3, -4) and (-2, 1) = [tex]\sqrt{(3+2)^2+(-4-1)^2}[/tex]
= [tex]\sqrt{50}[/tex]
= 7.07
4). Distance between (-1, -2) and (1, -4) = [tex]\sqrt{(1+1)^2+(-4+2)^2}[/tex]
= [tex]\sqrt{8}[/tex]
= 2.83
5). Distance between (5, -2) and (-1, -1) = [tex]\sqrt{(5+1)^2+(-2+1)^2}[/tex]
= [tex]\sqrt{37}[/tex]
= 6.08
Therefore, increasing order of the distance will be 2.24 > 2.83 > 4.47 > 6.08 > 7.07
Answer:
Use the formula of distance between two points (x₁, y₁) and (x₂, y₂),
Distance =
1). Distance between (4, 1) and (2, 2) =

2). Distance between (-5, 2) and (-3, -2) =

4). Distance between (-1, -2) and (1, -4) =

= 2.83
5). Distance between (5, -2) and (-1, -1) =

Answer:

Step-by-step explanation:
According To The Question,
Given, A culture of bacteria has an initial population of 41000 bacteria and doubles in every 5 hours & [tex]P_{t} = P_{i}*(2)^{\frac{d}{t} }[/tex] .Now, for the population of bacteria in the culture after 14 hours is [tex]P_{t}[/tex] . We have Initial Population([tex]P_{i}[/tex])=41000 , d=14 & t=5 .
Put These Value in Above Formula, We get

Given:
Rahul and Swapnil brought an equal amount of money for shopping.
Rahul spend rupees 95 and Swapnil spend rupees 350.
After that Swapnil had [tex]\dfrac{4}{7}[/tex] of what Rahul had left.
To find:
How much money did Rahul have left after shopping.
Solution:
Let x be the amount brought by both Rahul and Swapnil.
Rahul spend rupees 95 and Swapnil spend rupees 350. So, the remaining amounts are:
Rahul's remaining amount = [tex]x-95[/tex]
Swapnil's remaining amount = [tex]x-350[/tex]
After that Swapnil had [tex]\dfrac{4}{7}[/tex] of what Rahul had left.
[tex](x-350)=\dfrac{4}{7}\times (x-95)[/tex]
[tex]7(x-350)=4(x-95)[/tex]
[tex]7x-2450=4x-380[/tex]
Isolate the variable terms.
[tex]7x-4x=2450-380[/tex]
[tex]3x=2070[/tex]
[tex]x=\dfrac{2070}{3}[/tex]
[tex]x=690[/tex]
Now, the remaining amount of Rahul is:
[tex]x-95=690-95[/tex]
[tex]x-95=595[/tex]
Therefore, the correct option is B.

Ramón and Merissa are driving to New York City after college. The first 300 miles they spend $12.50 on gas.
At this rate, if they drive 960 miles, how much will the gas cost for the entire trip?
Answers
Answer:
the gas cost for the entire trip is $77
Step-by-step explanation:
Given that
For the first 300 miles, it spend $12.50 on gas
We need to find out the gas cost for the overall trip at the time when it drives 960 miles
So, it should be
= 960 miles ÷ $12.50
= $76.80
= $77
Hence, the gas cost for the entire trip is $77
