Answer:
Step-by-step explanation:
8/16=8:16
2/4=2:4
Answer:
Yes, the ratios 2/4 and 8/16 form a proportion. To check if two ratios form a proportion, you can cross-multiply and see if the products are equal. In this case, 2 x 16 = 4 x 8 = 32, so the products are equal. Therefore, the ratios form a proportion.
What is RS? Please help will give Brainlyest.
Answer:
RS = 47Step-by-step explanation:
RV=VU and SW=WT ⇒ [tex]VW=\dfrac{RS+UT}{2}[/tex]
Therefore:
[tex]3x+5=\dfrac{2x+15+6x-37}{2}\\\\3x+5=\dfrac{8x-22}{2}[/tex]
3x + 5 = 4x - 11 {subtract 5 from both sides)
3x = 4x - 16 {subtract 4x from both sides)
-x = -16 {divide both sides by (-1)}
x=16
So:
RS = 2x + 15 = 2×16 + 15 = 32 + 15 = 47

In the garden the total number of pepper plants is 15 and the total number of tomato plants
is 12. What is the ratio of pepper plants to tomato plants in the garden?
Mr. Bradley purchased 20 trays of flowers. Each tray had 3 dozen flowers. Mr. Bradley's total for all the flowers was 273.60. All the flowers were the same price. How much did each flowers cost?
Answer: Each flower costs $0.38.
Step-by-step explanation:
1 dozen = 12 units
Flowers in each tray = 3 dozen = 3 x 12 = 36
Flowers in 20 trays = 20 x 36 = 720
Price of 20 trays = $ 273.60
Price of each flower = (Price of 20 trays ) ÷ (Flowers in 20 trays)
= 273.60 ÷ 720
= $ 0.38
Hence, each flower costs $0.38.

Mrs. Palma took her coworkers out to dinner yesterday and their subtotal was $72.39
If the sales tax is 5% and she plans to leave a 20% gratuity after the tax it is added, how much will Mrs. Palma spend total on dinner?
A) $82.54
B) $86.87
C) $90.48
D) $91.21
Answer:
C) $90.48
Step-by-step explanation:
72.39*.2=14.478
72.39*.05=3.6195
14.478+3.6195=18.0975
18.0975+72.39=90.4875
50m.cloth costs 2500$.so how much meters will be bought in 1000$
Step-by-step explanation:
50m.cloth costs=2500$
we can write,
2500$cost for=50m.
1$ costs for=[tex]\tt{\dfrac{50}{2500} }[/tex] ⠀
=[tex]\tt{\dfrac{\cancel{50}}{\cancel{2500}} }[/tex]m. ⠀
=[tex]\tt{\dfrac{1}{50} }[/tex] m.⠀
So,
1000$ cost for ,
=[tex]\tt{\dfrac{1}{50}×1000 }[/tex]
=[tex]\tt{\dfrac{1}{\cancel{50}}×\cancel{1000 }}[/tex]
=[tex]\tt{20m. }[/tex] ⠀
[tex]\therefore[/tex] 20m. Will be bought in 1000$⠀
Answer:
The 20m of cloth will be bought in $1000.
Step-by-step explanation:
Given that :-
The cost of 50m cloth is $2500.
We need to find :-
How much meters of cloth will be bought in $1000.
Let us assume :
We bought x meters of cloth in $1000.
According to the question
50 = 2500
x = 1000
Using cross multiplication method.50 × 1000 = 2500 × x
50000 = 2500x
Divide both side by 2500.[tex]\frac{50000}{2500} \\ [/tex] = [tex]\frac{2500x}{2500} \\ [/tex]
Reduce the fractions.20 = x
Hence,
The 20m of cloth will be bought in $1000.

f the ratio 3x : 5y equals the ratio 7 : 11, then the ratio x : y equals what?
2.3 : 2.2
Given:3x : 5y and 7 : 11
Step-by-step solution:3x : 5y
7 : 11
To find x:
3x = 7
x = 7/3 (Bring 3 over to 7 to divide)
x = 2.3 OR 2/1/3
To find y:
5y = 11
y = 11/5 (Bring 5 over to 11 to divide)
y = 2.2 OR 2/1/5
So,
x = 2.3
y = 2.2
Therefore, the answer is:
x : y = 2.3 : 2.2

a√10 = 5√10a = 5What is the measure of angle Y?
Answer:
Y=70
Step-by-step explanation:
For starters, all the interior angles inside a pentagon add up to 540. This number can be found for any polygon with the forumla (n-2)180. N stands for the number of sides and then you plug it into the equation. For instance, if we wanted to find it for a triangle, we would see that the triangle has three sides and plug it into the formula. (3-2)180 which equals 180. For the ptenagon we take the fact that it has five sides and add it into the equation. (5-2)180 which equals 540. So now that we know all the interior angles are supposed to add up to 540, we can find the value of Y. So let's start by finding what amount we already have.
T=110
A=150
D=120
O=90 (this is beacuse of the right angle square placed which equals 90 degrees)
All those angles add to 470 degrees. So to find the last angle, you would subtract our total of 470 from our interior angle total of 540.
540-470=70
Y=70.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 152,149,146
Answer:
the 30th term is 239
Step-by-step explanation:
The computation of the 30th term is as follows:
As we know that
a_n = a_1 + (n-1)d
where
a_1 is the first number is the sequence
n = the term
And, d = common difference
Now based on this, the 30th term is
= 152 + (30 - 1) × 3
= 152 + 29 × 3
= 152 + 87
= 239
Hence, the 30th term is 239

O A. Yes, because R is the result of reflecting Q across the x-axis.
B. Yes, because R is the result of reflecting across the line y = x.
OC. No, because R can only be obtained from Q by a series of rigid transformations.
OD. No, because R cannot be obtained from Q by a series of rotations and translations.
OE. Yes, because R is the result of rotating Q by 90° counter-clockwise about the origin.

A bag has 2 blue, 3 red, and 5 yellow tiles. Find the probability of picking a blue tile.
Given:
A bag has 2 blue, 3 red, and 5 yellow tiles.
To find:
The probability of picking a blue tile.
Solution:
We have,
Number of blue tiles = 2
Number of red tiles = 3
Number of yellow tiles = 5
Total number of tiles = [tex]2+3+5[/tex]
= [tex]10[/tex]
Now, the probability of picking a blue tile is
[tex]P(\text{Blue})=\dfrac{\text{Number of blue tiles}}{\text{Total number of tiles}}[/tex]
[tex]P(\text{Blue})=\dfrac{2}{10}[/tex]
[tex]P(\text{Blue})=0.2[/tex]
Therefore, the probability of picking a blue tile is 0.2.
