7. Bruno noticed today's gasoline price at the local convenience store was advertised as $3.40 per gallon. This price is 15% above last year's price. Calculate last year's price. $ 3.55 O $ 3.25 O $ 2.96 O $ 2.40
Answer:
I'm pretty sure it $2.96
Answer:
option c) $ 2.96
Step-by-step explanation:
15% = 15 /100 = 0.15
Let last year's price = $ x
x + 15% of x = $ 3.40
x + 0.15*x = 3.40
x + 0.15x = 3.40 {Add like terms}
1.15x = 3.40 {Divide both sides by 1.15}
1.15x/1.15=3.40/1.15
x = 2.956
Last year's price = $ 2.96

Find the Product: (x+9i)^2
Answer:
x² + 18xi - 81
Step-by-step explanation:
FOIL - First, Outside, Inside, Last
Step 1: Write out expression
(x + 9i)²
Step 2: Expand
(x + 9i)(x + 9i)
Step 3: FOIL
F - x²
O - 9xi
I - 9xi
L - 81i²
Step 4: Combine
x² + 18xi + 81i²
Step 5: Simplify
i² = -1
x² + 18xi + 81(-1)
x² + 18xi - 81

What is the equation of a line with a slope of -3 and a y-intercept of 4?
Answer:
y = -3x+4Step-by-step explanation:
the equation of a line is: y = mx+b
Where:
m is the slope, and
b is the y-intercept
Replace m with -3 and replace b with 4, in the equation y=mx+b.
[tex]m = -3\\b =4\\\\y =mx+b\\\\y =-3x+4[/tex]

Answer:
D) Isometría
Step-by-step explanation:
Hola, D es la respuesta correcta porque la isometría no es una transformación isométrica, veamos por qué.
Una Transformación Isométrica es el cambio de forma, pero no por tamaño ni forma de la figura.
A. La traslación es una transformación isométrica porque desliza la figura a otro lugar, sin afectar su forma o tamaño.
B. La simetría es una transformación isométrica porque técnicamente es un reflejo, una vez más no afecta el tamaño o la forma de la figura.
C. La rotación es una transformación isométrica porque gira la figura, sin afectar el tamaño o la forma de la figura.
E. La teselación es una transformación isométrica porque une la misma forma, sin afectar el tamaño o la forma de la figura.
Dejándonos con D.

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?
–10
–5
–3
–1
Answer: -1
Step-by-step explanation:
Given by your question
2(3x-1)≥4x-6
Distributive property to take off the parentheses
2×3x-2×1≥4x-6
6x-2≥4x-6
Subtract 4x on both sides (Subtractive property of equality)
6x-2-4x≥4x-6-4x
2x-2≥-6
Add 2 on both sides (Addition property of equality)
2x-2+2≥-6+2
2x≥-4
Divide 2 on both sides (Division property of equality)
2/2 x≥-4/2
x≥-2
----------------------------------------------------------------------------
Looking at the options you've provided.
-10 INCORRECT, it is not greater or equal to -2
-5 INCORRECT, it is not greater or equal to -2
-3 INCORRECT, it is not greater or equal to -2
-1 CORRECT, it is greater than -2
Hope this helps!! :)

x = - 1
Step-by-step explanation:2(3x – 1) ≥ 4x – 6
6x - 2 ≥ 4x - 6
6x - 4x ≥ 2 - 6
2x ≥ - 4
x ≥ - 2
x ∈ [ - 2 ; + oo )
x = - 1
Here’s the picture for it
Answer:
Option (B)
Step-by-step explanation:
[tex]\begin{bmatrix}4 & 0\\ -1 & 2\\ -3 & -1\end{bmatrix}\times\begin{bmatrix}0 & 1 \\ -3 & 1\end{bmatrix}[/tex]
In the multiplication of two matrices we multiply the column of 1st matrix with the row of the 2nd matrix and add them.
= [tex]\begin{bmatrix}(4\times 0)+0(-3) &(4)1+0(1)\\ (-1)0+2(-3) &(-1)1+2(1)\\ (-3)0+(-1)(-3) &(-3)1+(-1)1 \end{bmatrix}[/tex]
= [tex]\begin{bmatrix}0 &4\\ -6 &1\\ 3 &-4 \end{bmatrix}[/tex]
Therefore, Option (B) will be the answer.

An electric pole, 14 metres high, casts a shadow of 10 metres. Find the height of a tree that casts
a shadow of 15 metres under similar conditions.
As shadow is directly propotional to height, we can say that,
Height/Shadow =k, where k is a constant.
So, in case of electric pole,
1410=k→(1)
In case of tree,
HT15=k→(2), where HT is height of tree
So, from (1) and (2),
1410=HT15
HT=14∗1510=21m
So, height of tree is 21 meters.
hope it helps thank youuuu

A jacket that normally sells for $45 is on sale with 20% off. What is the sale price? in dollars
Answer:
Step-by-step explanation:
The sales price would be $36.00
How I got this answer:
Discount: (45 x 20)/100 = $9.00 the nine dollars is your discount.
Final pricing:
45 - 9.00 = $36.00 when you subtract the cost with the discount you should get thirty-six dollars.
A box measuring 11 inches by 10 inches by 7 inches is filled with solid wooden cubical blocks, each measuring 3 inches per side. How many wooden blocks can fit into the box
Answer:
28
Step-by-step explanation:
[tex]number \: of \: wooden \: blocks \\ = \frac{volume \: of \: box}{volume \: of \: one \: wooden \: block} \\ = \frac{11 \times 10 \times 7}{3 \times 3 \times 3} \\ = \frac{770}{27} \\ = 28.51 \\ [/tex]
Thus, there would be 28 full wooden blocks in the box.
Answer: 28 wooden blocks
Step-by-step explanation: First you must find the volume of the box with the formula: L × W × H so, 10 × 11 × 7 = 770 inches³. Second you must find the volume of the wooden blocks with the formula: x³ ( 'x' is the value of the side of the cube ) so, 3 × 3 × 3 = 27 inches³. Now you can divide the volume of the box by the volume of the wooden block = 770 ÷ 27 = 28.518...*
* Always only count the whole numbers.
