SOMEONE PLEASE HELP IF YK GEOMETRYYY IVE ASKED THIS QUESTION 3 TIMES NOWW SO PLEASEEE HELP MEEEE
Answer: what is your question
Step-by-step explanation:
Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Krystal spent $114 on 1 daylily and 12 pots of ivy. Danielle spent $150 on 10 daylilies and 10 pots of ivy. Find the cost of each item.
Answer:
$9 and $6Step-by-step explanation:
Let the cost of daylilies = d and ivy = i, then we have below equations:
d + 12i = 11410d + 10i = 150Simplify the second equation:
d + i = 15Subtract the second equation from the first:
d - d + 12i - i = 114 - 1511i = 99i = 9, ivy costs $9Now find d:
d = 15 - 9 = 6, daylilies cost $6Can anyone help me with this question? <3 please and thank you!
Answer: 3/2 I’m on something similar rn
Step-by-step explanation:
Write the equation of a line with a slope of 3 that passes through (-3,2).
Answer:
y = 3x + 11
Step-by-step explanation:
Substitute the information into the point-slope form equation.
Point-slope form: y - y₁ = m(x - x₁)
y - 2 = 3(x - (-3))
y - 2 = 3(x + 3)
y - 2 = 3x + 9
y = 3x + 11

any answers? im bit stuck on this
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.

m=15
How do I show work for this tho?
Answer:
Use substitution method

Ms.Fernandez needs to buy new carpet for her bedroom floor a model of the floor is shown on the right. If each square ft of carpet costs $2 how much will it cost her to buy the carpet
Answer:
Step-by-step explanation:
Suppose the length of the carpet is x ft.
and the breadth of the carpet is y ft.
So the area of the rectangular shape =[tex]length\times breadth[/tex]
Area=[tex]x\times y\ ft.^2[/tex]
Cost of carpet
[tex]=Area\times rate\\=xy\times 2\\=\$\ 2xy[/tex]

A traffic cone has a diameter of 10 inches and a height of 27 inches.
Part A
Find the volume of the cone.
Answer:
V=706.85
Step-by-step explanation:
Well, first of when you want to find the volume of the cone you need to have a radius and hieght. And the radius is half the diameter, so divide the diameter into half: 10/2=5 in. and you already have the height so just plug in the numbers.
Formula: V= [tex]\frac{1}{3}[/tex][tex]\pi[/tex][tex]r^{2}[/tex]h ---> V= [tex]\frac{1}{3}[/tex][tex]\pi[/tex]([tex]5^{2}[/tex])(27)
And put the plugged in formula in your calculator and you'll find the answer!
V=706.85

The quotient of a number and 6 minus -1/3 is equal to the quotient of the number and 8. What is the number?
Answer:
x = 8
Step-by-step explanation:
Let the number = x
x/6 - 1/3 = x/8
-1/3 = x/8 - x/6
-1/3 = (6x-8x)/48
-1/3 = -2/48x
Divide both sides by -2/48
x = -1/3 ÷ -2/48
= -1/3 × -48/2
= 48/6
= 8
x = 8
The number = 8

Answer:
I think it might be e=5h someone please correct me if I'm wrong
Step-by-step explanation:
Answer:
e = 5h
Step-by-step explanation:
To find the unit rate (money earned per hour), we divide 10 by 2, which gets us 5. That means $5 is earned per house. If h is the number of houses shoveled, and he earns $5 per house, we can write that as 5h. If e is the money earned, we can write this whole thing as e = 5h.

Amy and Ben share £21 between them in the ratio 5 : 2. How much does Amy get?
(Im really sorry I just don't understand ratio.)
Answer:
✑ [tex] \underline{ \underline{ \sf{First ,\: Let's \: learn \: about \: the \: ratio}}} : [/tex]
Let us consider , there are 30 boys and 40 girls in a school. So, the ratio of number of boys to number of girls = [tex] \sf{ \frac{30}{40} = \frac{3}{4} = 3:4}[/tex] and read as 3 is to 4. We can say , the ratio compares two of more quantities of same unit. Until two quantities have same units , it is meaningless to compare by ratio. So, to find the ratio of two quantities , it is necessary to express them in same unit or of same kind. Since , they are in division form. So ,ratio is unit less quantity. Thus , the ratio is a comparison of two quantities of the same kind in division which doesn't have any units. For example : [tex] \sf{ \frac{a}{b}} [/tex] is a ratio and is read as ' a is to b ' in which ' a : is antecedent and ' b ' is called consequent.
✎ [tex] \underline{ \underline{ \sf{Now \: let's \: solve : }}}[/tex]
☪ [tex] \underline{ \sf{Solution}} : [/tex]
£ 21 is to be divided between Amy and Ben in the ratio 5 : 2. So, let Amy get £ 5x and Ben get £ 2x.
Then , According to the question , [tex] \text{5x +2x = 21}[/tex]
Solve for x :
⇝ [tex] \sf{7x = 21}[/tex]
⇝ [tex] \sf{ \frac{7x}{7} = \frac{21}{7} }[/tex]
⇝ [tex] \sf{x = 3}[/tex]
The value of x is 3. Now , substitute the value of x in 5x :
Amy received £ 5x = 5 × 3 = £ 15 .
☥ [tex] \boxed{ \boxed{ \tt{Our \: final \: answer \: is \bold{£ \: 15}}}}[/tex]

1/5 - 1/6
Plz ans. Fasttt
Answer: 1/30
5 and 6 both have a common factor of 30
30 will be our ned denominator
1/5 needs to be multipliued by 6
(since 5 times 6 is 30)
and
1/6 needs top be multiplied by 5
(since 6 times 5 is 30)
then you get 6/30 - 5/30 and that is just 1/30

How many solutions?
y = 5(x – 4)
4x + 12 = -y
Answer:
One solution, x = 8/9
Step-by-step explanation:
One way to solve this is to take one equation and substitute into the other and then solve. So, take y=5(x-4) and put that into the other equation.
4x + 12 = -y
4x + 12 = -(5(x-4)) <--- substitution here
4x + 12 = -5(x-4)
4x + 12 = -5x + 20 <-- simplifying
4x + 5x = 20 - 12
9x = 8
x = 8/9
