Answer:
$88.81
Step-by-step explanation:
to find tip, multiply 77.23 and .15 to get $11.58
total cost = meal + tip
total cost = 77.23 + 11.58 which equals $88.81

This is my question I need the answer to
4. You have 36 pairs of running shoes. Let x be the
number of Nikes and y be the number of Adidas shoes
you own. You own twice as many Nikes as Adidas
shoes.
d
Write and solve a linear system of equations to find the
number of each brand of shoes.
Answer:
Nikes: 24 pairsAdidas: 12 pairsStep-by-step explanation:
The system of equations can be written ...
x + y = 36
x = 2y
__
The system can be solve by substituting for x:
(2y) +y = 36
y = 12 . . . . . . divide by 3
x = 2(12) = 24
There are 24 pairs of Nikes and 12 pairs of Adidas.

[tex]x = 0[/tex]
[tex]y = 7[/tex]
; about the y-axis
on this one, we proceed the same as the other, we start off by graphing them, Check the picture below. Now, we have a solid horizontal line at y = 7, that'd be our boundary, and a parabola that has a vertex at the origin, that's our other boundary, from 0 to 7.
In this case, is a solid area from the curve to the axis of rotation, so we can simply use the "disk" method to get the volume, lemme do it in the same way as "area under the curve", assuming h(y) = 0 for the axis of rotation
[tex]\textit{area under the curve}\\ \stackrel{f(y)}{2\sqrt{3y}}~~ - ~~\stackrel{h(y)}{0}\qquad \implies 2\sqrt{3y} \\\\\\ \displaystyle\int_{0}^7\pi \left( 2\sqrt{3y} \right)^2 dy\implies \int_{0}^7\pi(12y)dy\implies 12\pi \int_{0}^7 y\cdot dy \\\\\\ 12\pi \cdot \left. \cfrac{y^2}{2} \right]_{0}^7\implies12\pi \cdot \cfrac{49}{2}\implies 294\pi[/tex]

What is the number pattern?A number pattern is a pattern in a series of numbers that represents the common relationship between the numbers.
When all the terms of a geometric sequence are added, then that expression is called geometric series.
We are given the series as;
3, 4, 7, 16, 11, 64, …
If we separate the numbers that in order are in the even place of the odd ones, we would have :
3, 4, 7, 16, 11, 64,..
If we finish in 1 then they increase by 1 in 1, while in 2.- they increase in odd numbers, the following number is: 55
The correct option is A.

Answer:
Option D
Step-by-step explanation:
Step 1: Determine the correct option
Option A, this option doesn't work because -3.46 is not greater than -2 1/3. Although the number 3 is greater than 2, these numbers are negative therefore the bigger the negative number, the smaller the number actually is.
Option B, this option doesn't work because 16/5 is not greater than 6. If we convert 16/5 into a decimal we get 3.2 and this number isn't bigger than 6.
Option C, this option doesn't work because once again it states that -3.46 is greater than -2 1/3 when in reality it's actually smaller.
Option D, this option does work because everything goes according the way it should. -3.46 is smaller than -2 1/3 and -2 1/3 is smaller than -3/4 and -3/4 is smaller than 16/5 and 16/5 is smaller than 6.
Answer: Option D

LAST ATTEMPT MARKING AS BRAINLIEST!! (Graph the image of the figure using the dilation given)
Answers:
[tex]I(-2,-1) \to I \ ' \ (-5,-2.5)\\\\J(-1,2) \to J \ ' \ (-2.5,5)\\\\K(2,-1) \to K \ ' \ (5,-2.5)\\\\[/tex]
===============================================
Explanation:
Since the center of dilation is the origin, we multiply each preimage coordinate by 2.5 (which is the scale factor).
For example, the preimage point J(-1, 2) moves to J ' (-2.5, 5)
-1*2.5 = -2.52*2.5 = 5This will cause the image triangle I'J'K' to be larger than the preimage IJK. Specifically, each side of the image is 2.5 times longer compared to the preimage.
Answer:
i' (-5, -2.5) J' (-2.5, 5) K' (5, -2.5)
Step-by-step explanation:
you just take the original coordinates and multiply them by 2.5

PLS PLS PLS HELP ON GEOMETRY PLS
Answer:
40 degrees
Step-by-step explanation:
Since triangle HJL is isosceles, angle HJL is congruent to HLJ, so it is 75 degrees.
Angle HLM is linear with HLJ, so they add up to 180, so HLM = 105 degrees.
Triangle HLM adds to 180 degrees, so 180 - 35 - 105 = 40

Step-by-step explanation:
*Note:
Integrating a piecewise function requires you to integrate both parts.
Step 1: Define
Identify.
[tex]\displaystyle f(x) = \left \{ {{8x - 1 ,\ x \leq 4} \atop {31 ,\ x \geq 4}} \right.[/tex]
[tex]\displaystyle \int {f(x)} \, dx = \left \{ {{g(x) + C ,\ x \leq 4} \atop {31x + C ,\ x \geq 4}} \right.[/tex]
Step 2: Find function g(x)
We can see that the 2nd part of the piecewise function already has been integrated:

In the rectangular trapezoid ABCD AC is driven by a CD (see figure).
Find the width of the trapezoid if AC = 3, AD = 5.
Answer:
solution given:
let's see only in a right-angled triangle Δ ACD.
AC=3 units
AD=5 units
since Δ ACD is a right-angled triangle. It satisfies Pythagoras law
[tex]AD^{2}=AC^{2}+CD^{2}[/tex]
25=9+[tex]CD^2[/tex]
[tex]CD^2[/tex]=25-9=16
[tex]CD=\sqrt{16} =4 units[/tex]
Now
Area of rectangle Δ ACD=[tex]\frac{1}{2} CD*AC=\frac{1}{2}*4*3=6\: square \:units[/tex]
similarly,
[tex]\frac{1}{2} AD*CE=6\: square \:units\\ 5*CE=6*2\\CE=\frac{12}{5}=2.4 units[/tex]
since AB=CE=2.4 units
Δ ACE is a right-angled triangle. It satisfies Pythagoras law.
[tex]AC^{2}=AE^{2}+CE^{2}\\3^2=AE^2+2.4^2\\9-5.76=AE^2\\AE and BC=\sqrt{1.24} =1.11 units[/tex]
now
area of trapezoid=area ofΔACD+Area of ΔABC
=6+[tex]\frac{1}{2}AB*BC=6+\frac{1}{2}*2.4*1.11=6+1.33 =7.33\: square \:units[/tex]

Give me some hint please
Solve for x: 5x + 15 = 28
A: 43/5
B: 13/5
C: 13
D: 43
[tex]\mathfrak{5x + 15 = 28} [/tex]
[tex]\mathfrak{5x = 28-15} [/tex]
[tex]\mathfrak{5x = 13} [/tex]
[tex]\boxed{\mathfrak{x = \dfrac{13}{5}}} [/tex] → option B.
[tex]\mathbb{MIREU} [/tex]
Answer:
B
Step-by-step explanation:
The first thing you need to do is,
28 - 15
which is 13.
Now look at the answer choices and multiply them by 5.
It cannot be C or D because it would not fit the equation.
If anyone of them equal 13 then it is the answer.
Now lets try it.
43/5 = 8.6
13/5 = 2.6
8.6 times 5 is way to big so A is not it.
2.6 times 5 is 13.
So it is B.
Express the dollowing fraction in decimal form as a terminating decimal or as a infinite repeating decimal 3/16
Answer:
3/16 as a decimal is equal to 0.1875.
Let's convert the given fraction to a decimal number.
Explanation:
To convert any fraction to decimal form, we just need to divide its numerator by denominator.
Here the fraction is 3/16 which means we need to perform 3 ÷ 16.
So, 3/16 is equal to 0.1875.
