Mia used 1/7 of an ounce of nuts to make 1/5 of a cake. How many ounces of nuts are needed to make a whole cake?
Answer:
For this case we can apply the following proportional rule:
Step-by-step explanation:
1/7 nuts. x
------------ = ----------
1/5 cake. cake
and solving for x we got:
x = 1/7
------- = 5/7 nuts
1/5
then the answer for this case would be 5/7 nuts

A Lime bike charges $2 for
a flat fee plus $0.50 a
minute. A different bike
charges $3.80 for a flat
fee plus $0.20 a minute.
After how many minutes
(x), will the price (y) be
the same for both bikes?
Answer:
5 minutes
Explanation:
.5x + 2 = y
.2x + 3.8 = y
.5x + 2 = .2x + 3.8
-.2x -.2x
.3x + 2 = 3.8
-2 -2
.3x = 1.8
.3 .3
x = 5
After 5 minutes, both bikes will be at the same price.

What is the slope y+2=1/4(x-3)
Answer:
[tex]m=\frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]y+2=\frac{1}{4}(x-3)[/tex]
Required
Find the slope
[tex]y+2=\frac{1}{4}(x-3)[/tex]
Subtract 2 from both sides
[tex]y+2-2=\frac{1}{4}(x-3) - 2[/tex]
[tex]y=\frac{1}{4}(x-3) - 2[/tex]
Open bracket
[tex]y=\frac{1}{4}x-\frac{1}{4}*3 - 2[/tex]
[tex]y=\frac{1}{4}x-\frac{3}{4} - 2[/tex]
Take LCM
[tex]y=\frac{1}{4}x+\frac{-3 - 8}{4}[/tex]
[tex]y=\frac{1}{4}x+\frac{-11}{4}[/tex]
[tex]y=\frac{1}{4}x-\frac{11}{4}[/tex]
An equation has the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparing: [tex]y = mx + b[/tex] and [tex]y=\frac{1}{4}x-\frac{11}{4}[/tex]
[tex]m=\frac{1}{4}[/tex]
So, the slope is 1/4

Which of the following numbers is irrational? -9/5 , sqrt (5) , 7/3 , sqrt (9)
I WILL mark brainliest!
Answer:
[tex]\large\boxed { \ ANS = \sqrt{5} }[/tex]
Step-by-step explanation:
Irrational numbers are numbers that cannot be written as simple fractions. All the numbers listed above except for [tex]\sqrt{5}[/tex] cannot be written as fractions.
• [tex]\frac{7}{3}[/tex] is already a fraction
• [tex]\frac{-9}{5}[/tex] is also already a fraction
• [tex]\sqrt{9}[/tex] is 3 and 3 can be written as [tex]\frac{3}{1}[/tex]
• [tex]\sqrt{5}[/tex] is an irrational algebraic number and cannot be written as a simple fraction since it is equal to

[3x-2]÷4=2x-8
Can someone help
Answer:
Step-by-step explanation:
[3x-2]÷4=2x-8
3x-2 = 4·(2x-8)
3x-2 = 8x-32
-2 = 5x-32
30 = 5x
x = 6
Answer:
(3x-2)/4= 2x-8 x=6
Step-by-step explanation:
(3x-2)/4 times 4= 2x-8
Multiply both sides by 4
3x-2/4 times 4= 2x times 4-8 time 4
Simplify
3x= 8x = 8x-30-8x
Subtract 8x from both sides
3x-8x=8x-30-8x
Simplify
-5x=-30
Divide both sides by -5
-5x/-5 = -30/-5
Simplify so you get x=6

4. The price of a sweater is $5 less than the price of the shirt. If four sweaters and
three shirts cost $200, find the cost of each shirt and sweater.
Answer:
Form an equation:
let x be the price of a shirt
Then, the price of a sweater would be x - 5
So you would have:
4(x - 5) + 3x = 200
simplify
4x - 20 + 3x = 200
7x - 20 = 200
add 20 to both sides
7x = 220
divide both sides by 7
x = about 31.43
That means the cost of the sweater would be 31.43 - 5 = 26.43

Answer:
A) 2481.156[tex]\pi[/tex] cm³
Step-by-step explanation:
The formula for volume of a sphere is: [tex]\frac{4}{3} \pi r^{3}[/tex]. In this case, the radius is 12.3. 12.3 cubed is: 1860.867. 1860.867 x 4 is 7443.468. 7443.468 divided by 3 is 2481.156. Since we haven't multiplied by pi yet, the answer would be 2481.156[tex]\pi[/tex].

V = ? (Type an exact answer in terms of pi)
Answer:
[tex]V=47239.2\pi [/tex]
Step-by-step explanation:
We are given that
[tex]y=\sqrt{x}[/tex]
y=0
[tex]x=81[/tex]
When y=0 then x=0
Using shell method
Volume of solid
[tex]V=2\pi \int_{a}^{b}xf(x)dx[/tex]
Using the formula
Volume of solid
[tex]V=2\pi \int_{0}^{81} x(\sqrt{x})dx[/tex]
[tex]V=2\pi \int_{0}^{81}x^{\frac{3}{2}}dx[/tex]
[tex]V=2\pi [\frac{2}{5}x^{\frac{5}{2}}]^{81}_{0}[/tex]
[tex]V=2\pi\times \frac{2}{5}((81)^{\frac{5}{2}})[/tex]

HELP PLSSSSSS!!! answer all pls
Answer:
See below.
Step-by-step explanation:
STEP 1: If you write the given terms all with denominators of 16, they are 28/16, 25/16, 22/16, 19/16, __, ____, ____, 7/16, 4/16.
STEP 2: The terms decrease by 3/16 for each step.
RULE: Term 1 = 7/4 and term (n + 1) = term 'n' - 3/16
The operation for increasing by the same amount every step is addition.
The operation for decreasing by the same amount every step is subtraction.
STEP 3: The rule is that the terms decrease by 3/16 at each step.
So the next 3 terms after 19/16 will be 16/16, 13/16, and 10/16.
Reformat them and you have 1, 13/16, 5/8.
So now the completed sequence is 1&3/4, 1&9/16, 1&3/8, 1&3/16, 1, 13/16, 5/8, 7/16, 1/4.

Answer:
y = 1/5x -2
Step-by-step explanation:
When a point and slope are given, sometimes it is easiest to start with the point-slope form of the equation. Then it can be rearranged to the desired form.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -0 = 1/5(x -10) . . . . . line with slope 1/5 through point (10, 0)
y = 1/5x -2 . . . . . . . eliminate parentheses to get slope-intercept form

The scale for a blueprintis 1 cm: 50 in. What is the lengthon the blueprint for a bathroom wall that is 150 inches long
Answer:
The answer should be 3cm
Step-by-step explanation:
The way you worded it was kind of confusing so pardon me if the answer isnt the correct answer you were looking for. But I suppose that if 1 cm is 50 in. than 150 in. would be 3 cm. Because 50 + 50 + 50 = 150. And if it is 1 cm. per 50 in. than that would be 3 cm. I hope this answered your question! And if not.. again, im sorry.
Andy's little brother has a toy box that
contains 2 blue race cars, 1 green race car,
and 1 red race car. Andy removes 2 race cars
from the toy box without looking. If Andy
removes a blue car first and does not replace
it, which best represents the sample space
for the cars Andy removes?
Answer:
c.
Step-by-step explanation:
The solution is Option C.
Sample space is set A = { blue , blue } , { blue , green } , { blue , red }
What is union and intersection of sets?The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the sample space be represented as set A
Now , the equation will be
The number of blue cars = 2 blue cars
The number of green cars = 1 green car
The number of red cars = 1 red car
So , the total number of cars = 2 + 1 + 1 = 4 cars
Now , Andy removes 2 race cars from the toy box without looking
Let the first removed car be a blue car
So , the second car can have any value including a blue , green or white
And , the sample space is given by set A
Set A = { blue , blue } , { blue , green } , { blue , red }
Hence , the set is { blue , blue } , { blue , green } , { blue , red }

A clothing outlet had a sale on jackets. A jacket priced at $233 was on sale, selling for 70% (use 0.7) of its price. How much did customers have to pay for the jacket (ignore taxes)?
Answer:
Jackets cost $69.90.
Step-by-step explanation:
1. Multiply $233 by 70% (.70 as a decimal) to find how much less the jacket is.
2. Subtract that answer from the cost of the jacket.
233 * .70 = 163.1
233.00
163.10
$69.90
You can also multiply $233 by 30% and not have to subtract because your answer would BE the cost (70% + 30% = 100%).
233 * .30 = 69.90 $69.90

Q
Timo concluded:
"It's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations,
so the quadrilaterals are not similar."
Answer:
c
Step-by-step explanation:
The two quadrilaterals LMNR and PQNO are not similar. Timo tried to map one figure onto the other using rotation and dilation methods. He concluded that they are not similar because the rigid transformations like rotation preserve congruence and dilation will not change the shape but it changes its size. So, this results in no congruence.
What is rigid transformation?Rotations, reflections, and translations are known as rigid transformations. They do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.What is dilation?Dilation is not a rigid transformation, since they change the size of a figure. Dilation would not change the shape but changes the sizeThis would give us a similar, but not congruent figure.Here Timo used rotation and dilation on the two quadrilaterals LMNR and PQNO. So, this resulted in a change in the size of the quadrilaterals. Because of this, Timo concluded that "it's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations, so the quadrilaterals are not similar".
