Answer:
6
Step-by-step explanation:
40 - 21.40 = 18.6
18.6 - 15, for the amount he sets aside for shirt = 3.6 left to spend
3.6 divided by 0.58 = 6.20
so rounded, the answer should be 6 packages of skittles
help me please!!!!!!!
Answer:
C (-6,-8) → C' (6,8)
D (-2,-8) → D' (2,8)
E (-2,-4) → E' (2,4)
F (-6,-4) → F' (6,4)
Step-by-step explanation:
When you rotate a point 180° counterclockwise about the origin, the point A (x,y) becomes A' (-x,-y). So, if the points are positive, they will become negative.
Because all the points are negative, rotating them 180° counterclockwise will make them positive.
Hope that helps.
What is this answer and work shown please 5/2x -3 =2
Answer:
x = 2
Step-by-step explanation:
Given
[tex]\frac{5}{2}[/tex] x - 3 = 2 ( add 3 to both sides )
[tex]\frac{5}{2}[/tex] x = 5 ( multiply both sides by 2 to clear the fraction )
5x = 10 ( divide both sides by 5 )
x = 2

HELP I WILL GIVE BRANLIEST What is the slope of the line in the graph?
Answer:
the solpe is 1x or just x
Step-by-step explanation:
rise over run both are 1
Answer:
[tex]\boxed {\tt m=1}[/tex]
Step-by-step explanation:
The slope formula is:
[tex]m= \frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are points on the line.
Let's pick two points from the graph : (1,2) and (4,5). Match the variables and numbers, so:
[tex]x_1=1\\y_1=2\\x_2=4 \\y_2=5[/tex]
Substitute the values into the formula.
[tex]m=\frac{5-2}{4-1}[/tex]
Solve the numerator. Subtract 2 from 5.
[tex]m=\frac{3}{4-1}[/tex]
Solve the denominator. Subtract 1 from 4.
[tex]m=\frac{3}{3}[/tex]
Divide 3 by 3.
[tex]m=1[/tex]
The slope of the line is 1.
L varies directly with the square of Z. L is 12 when Z is 2. Find the value of L when Z is 4.
Answer:
L = 48
Step-by-step explanation:
Given that L varies directly with Z² , then the equation relating them is
L = kZ² ← k is the constant of variation
To find k use the condition L = 12 when Z = 2 , then
12 = k × 2² = 4k ( divide both sides by 4 )
3 = k
L = 3Z² ← equation of variation
When Z = 4 , then
L = 3 × 4² = 3 × 16 = 48
R/5 = 4/7 solve for r
Answer:
[tex]\large\boxed{R = 2 \frac{6}{7}}[/tex]
Step-by-step explanation:
R/5 = 4/7
Cross-multiply (numerator * opposite denominator = numerator * opposite denominator)
R(7) = 5(4)
Multiply
7R = 20
Divide both sides of the equation by 7
R = 20/7
Simplify
[tex]\large\boxed{R = 2 \frac{6}{7}}[/tex]

Which number is larger, 2 x 10^-3 or 3 x 10^-2? Explain.
Answer:
Step-by-step explanation:
[tex]2 \times 10^{-3}=\frac{2}{10^3}=\frac{2}{1000}=0.002\\3 \times 10^{-2}=\frac{3}{10^2}=\frac{3}{100}=0.03=0.030\\0.030>0.002\\so~3 \times 10^{-2} ~is~larger~than~the~other.[/tex]

The price of a ring was increased by 30% to £325. What was the price before the increase?
Please answer asap!!
Answer:
227.5
Step-by-step explanation:
Find the number that is increased by 30% to get to 325.
100-30 = 70.
In other words, what number is 70% of 325.
325 x .70 = 227.5
The original price of the ring was 227.5.
Check your work, 227.5 = 70% of X
227.5 / .70 = 325
Answer:
The cost before the increase is £250.
Step-by-step explanation:
Given that after 30% increases, the cost of the ring is £325 so we can assume that 130% is £325. Now, we have to form an expression in term of x where x represents the original cost :
[tex] \frac{130}{100} \times x = 325[/tex]
Next, we have to solve it :
[tex]x = 325 \div \frac{130}{100} [/tex]
[tex]x = 325 \times \frac{100}{130} [/tex]
[tex]x = 250[/tex]

Function h is a transformation of the parent exponential function, $(=) = 2*
h(t) = -3 2-
Which statement is true?
O A
Function h is a horizontal translation of function f.
OB.
Function h is a reflection and a translation of function f.
C.
Function h is a vertical translation of function f.
D.
Function his a reflection and a dilation of function f.
Answer:
D. function h is a reflection and a dilation of functionStep-by-step explanation:
Parent function:
f(x) =2^xTransformed function:
h(x) = -3•2^xTransformation applied:
f(x) → -f(x) = reflection over x-axis = vertical reflectionf(x) → 3f(x) = dilation or vertical stretchCorrect answer choice is:
D. function h is a reflection and a dilation of function f

1. Move the decimal to create the coefficient: 2.8500000
2. Write in scientific notation:
2.85 x 100
What is the value of x in the scientific notation?
Answer:
28,500,000 into scientific notation is 2.85 x 10⁷
2.85 x 100 in scientific notation is 2.85 x 10²
if you mean the multiplication symbol, it just means to multiply. otherwise, there i don't see an x anywhere else

What is the volume of this rectangular prism?
Answer: 5/8 cm^3
Step-by-step explanation:
V = l x w x h
l = 3/4 cm
w = 1/3 cm
h = 5/2 cm
V = (3/4 cm) x (1/3 cm) x (5/2 cm) = 15/24 cm^3 = 5/8 cm^3
Find and interpret the slope of the line containing the given points. (0,20) and (-8,0)
Answer:
The slope is: 20/-8, or -20/8
Step-by-step explanation:
to find the rate of change, you do change in y over change in x
so you minus the y numbers and minus the x numbers
so,
20-0/0-8 = 20/-8
or you can do
0-20/8-0 = -20/8
both of them are the same
sorry I'm really bad at explaining myself
hope this helps! :D
Answer:
Step-by-step explanation:
(0 - 20)/(-8 - 0)= -20/-8= 20/8= 5/4
