Area of the figure is 42 in²
Step-by-step explanation:
Step 1: The area of the figure can be found by calculating the sum of the areas of the rectangle and the right angled triangle.⇒ Area of the rectangle = length × width = 6 × 5 = 30 in²
⇒ Area of the triangle = 1/2 × base × height = 1/2 × 4 × 6 = 12 in²
∴ Area of the figure = 30 + 12 = 42 in²
Meg laid 15 tiles in 50 minutes. Jessica worked for 85 minutes a faster rate per tile than Meg. Select all of the rates that could be Jessica's rate.
Jessica's rate could be any rate greater than 0.1765 tiles per minute.
Explanation:To determine Jessica's rate, we first find Meg's rate by dividing the number of tiles laid by the time taken: [tex]\(Rate_{\text{Meg}} = \frac{15 \, \text{tiles}}{50 \, \text{minutes}} = 0.3 \, \text{tiles per minute}\).[/tex] Since Jessica works at a faster rate per tile than Meg, her rate is greater than 0.3 tiles per minute. To calculate the minimum rate Jessica could have, we consider the case where she completes one tile in 85 minutes: [tex]\(Rate_{\text{Jessica}} = \frac{1 \, \text{tile}}{85 \, \text{minutes}} \approx 0.0118 \, \text{tiles per minute}\)[/tex]. Therefore, Jessica's rate could be any value greater than 0.0118tiles per minute.
The rate Jessica could have falls within the range of 0.0118 to 0.3 tiles per minute, as she is working at a faster rate than Meg. The provided answer, 0.1765 tiles per minute, is within this range. Jessica's rate per tile is not limited to any specific value, but it must be greater than Meg's rate of 0.3 tiles per minute. In summary, Jessica could work at any rate greater than 0.0118 tiles per minute, making 0.1765 tiles per minute a valid option.

If 270°<θ<360°, and tan θ= - 1/2, what is the value of tan(−θ)?
Check the picture below.
let's recall that once we move an angle in the opposite direction of the 0-line or x-axis, we end up with a negative counterpart angle.
since we know that θ is on the IV Quadrant, then its negative counterpart must be across the line, and tangent is negative on the IV Quadrant, and positive on the I Quadrant.
If 270°<θ<360°, and tan θ= - 1/2, then the value of tan(-θ) is 1/2.
Let's start by understanding the given information. We are given that the angle θ lies between 270° and 360°, which means it is in the fourth quadrant of the unit circle. In this quadrant, both the sine and tangent functions are negative, while the cosine function is positive.
We are also given that tan(θ) = -1/2. To find the value of tan(-θ), we can use the identity for the tangent of a negative angle:
tan(-θ) = -tan(θ).
Now, let's find the value of tan(θ) using the given information. We know that tan(θ) = -1/2, and since θ is in the fourth quadrant, we can construct a right-angled triangle in which the opposite side is -1 and the adjacent side is 2. By applying the Pythagorean theorem (a² + b² = c²), we can find the length of the hypotenuse, which is
√(1² + 2²) = √5.
Now, we have all the information to find the value of tan(-θ) using the tangent identity for a negative angle:
tan(-θ) = -tan(θ).
Substituting tan(θ) = -1/2, we get:
tan(-θ) = -(-1/2) = 1/2.

Which function is shown in the graph below? On a coordinate plane, a curve goes through (0.33, negative 1), (1, 0), and (3, 1). y = log Subscript 0.4 Baseline x y = log Subscript 1 Baseline x y = log Subscript 3 Baseline x y = log Subscript 10 Baseline x
Answer:
y = ㏒₃ x
Step-by-step explanation:
Given: the points (0.33, -1), (1, 0), and (3, 1)
We will check which function goes through the previous points
we will use the point (3,1)
1) y = ㏒₀.₄ x
㏒₀.₄ x = ㏒₀.₄ 3 = -1.199 ≠ 1
2) y = ㏒₁ x
㏒₁ x = ㏒₁ 3 ⇒ unlogic condition
3) y = ㏒₃ x
㏒₃ x = ㏒₃ 3 = 1
4) y = ㏒₁₀ x
㏒₁₀ x = ㏒₁₀ 3 = 0.477 ≠ 1
So, from the previous explanation:
The function is y = ㏒₃ x
Another solution;
by drawing the four function we will find which function goes through the points (0.33, -1), (1, 0), and (3, 1)
See the attached figure.

In the equation above, a and b are constants. If the
equation has infinitely many solutions for x, what is
the value of b?
Answer:
a=4, b=5/2
Step-by-step explanation:
Assuming the given equation is
[tex]a(x + b) = 4x + 10[/tex]
We expand the left hand side to get:
[tex]ax + ab = 4x + 10[/tex]
If this equation must have infinitely many solutions, then
[tex]ax = 4x \\ \implies \: a = 4[/tex]
Also we must have
[tex]ab = 10[/tex]
Put a=4 to get:

Say you go kayaking over a 2 mile stretch of river. The river is flowing at a speed of 1mph. You go 2 miles upstream, and then 2 miles downstream, back to your starting point, for one round trip. Make a function for it, then give me the graph of this function. Use a share link from Desmos, or upload a picture, or scan the graph you made on a piece of paper. Remember to show all vertical asymptotes and any horizontal asymptote.
Answer:
4 mph
Step-by-step explanation:
Givens
Current = c = 2 mph
Alberta = r = ?
d = 2 mph upstream
d1 = 6 mph downstream
Formula
d = r * t
The time is the same so the formula becomes d/r = t
2/(r - 2) = 6/(r + 2)
Solution
Cross Multiply
2*(r + 2) = 6*(r - 2)
2r + 4 = 6r - 12 Subtract 2r from both sides
4 = 6r - 2r - 12 Combine the right.
4 = 4r - 12 Add 12 to both sides.
4 + 12 = 4r
16 = 4r Divide by 4
16/4 = 4r/4
r = 4

Nicole is hosting a large bridal shower for her friend and has $396 in her budget to rent a facility. The facility she chose for the party requires an $72 deposit plus $60 per hour. If there is no damage to the facility, one-half of the deposit is refunded. If Nicole expects to get the deposit refund, for how many hours can she rent the facility for the bridal shower?
Step-by-step explanation:
Nicole starts with the budget:
$395
Now, she only expects to pay half the deposit;
$72 ÷ 2 = $36
Subtract this from the budget:
$395 - $36 = $359
Divide by cost per hour:
$359 ÷ $60 = 5.983333... (3 repeating)
This means, Nicole can rent a maximum of 5 hours with her budget. The inequality would be

x = 45°
Solution:
Given data:
Measure of larger arc = 152°
Measure of smaller arc = 62°
If a tangent and a secant intersect at the exterior of a circle then the measure of angle formed is one-half the positive difference of the measures of the intercepted arcs.
[tex]$\Rightarrow x = \frac{1}{2}(\text{ larger arc }- \text{smaller arc} )[/tex]
[tex]$\Rightarrow x = \frac{1}{2}(152^\circ-62^\circ)[/tex]
[tex]$\Rightarrow x = \frac{1}{2}(90^\circ)[/tex]
⇒ x = 45°
The value of x is 45°.

The lowest elevation in Long Beach, California, is 7 feet below sea level. The elevation
of Death Valley is about 40 times lower than the elevation of Long Beach. What is the
approximate elevation of Death Valley?
A -280 feet
- 47 feet
-33 feet
D
- 6 feet
Answer:
Option A -280 feet
Step-by-step explanation:
Let
x ----> the lowest elevation in Long Beach, California in feet
y ----> the approximate elevation of Death Valley in feet
Remember that
An elevation below the sea level is negative and above the sea level is positive (The sea level is the level zero)
we know that
The lowest elevation in Long Beach, California, is 7 feet below sea level
so
[tex]x=-7\ ft[/tex]
The elevation of Death Valley is about 40 times lower than the elevation of Long Beach.
so
[tex]y=40x[/tex]
substitute the value of x
[tex]y=40(-7)=-280\ ft[/tex]
therefore
The approximate elevation of Death Valley is about 280 feet below the sea level

Sam is building a rectangular deck with an area of 80 square feet. He wants the length of the garden to equal
6 feet more than 2 times the width.
a. Enter an equation that expresses the area of the deck in terms of the width, w, of the deck.
b. What is the width of the deck?
Answer:
a b c d e f g the jgh hgghg
Step-by-step explanation:
Final answer:
Provides equations to find the area and width of a rectangular deck based on given information.
Explanation:
a. Let the width of the deck be w. The length is given as 6 feet more than 2 times the width, which translates to 2w + 6. The area of a rectangle is length multiplied by width, so for this case, the equation expressing the area in terms of the width is w(2w + 6) = 80.
b. By solving the equation w(2w + 6) = 80, we find the width of the deck to be 10 feet.

What is the equation of line W in slope intercept form?
Hey there!
Our goal is to create the slope intercept equation for line W, which requires two things that we need to find out: the slope and the y-intercept.
We see that Line W is parallel to line V. Therefore, they have the same slope. So, the slope of Line W is 10/7.
Now, we need to find the y-intercept. To do this, we will plug the slope and the point we are given into the slope intercept equation and solve for b.
-3= 10/7(-3)+b
-3= -4 2/7+b
b=1 2/7
Now, we plug this into our final slope intercept form.
y=10/7x+1 2/7

Solve each system by substitution.
6) y = 2x - 3
y=-8x + 17
Answer:
x=2
Step-by-step explanation:
Since they are both equal to y set them equal to each other: 2x-3=-8x+17
Subtract 17 from both sides: 2x-20=-8x
Subtract 2x from both sides: -20=-10x
Divide both sides by -10: 2=x
Answer: x = 2 and y = 1
Step-by-step explanation: What we have here is a pair of simultaneous equations and we have been instructed to solve by using the substitution method.
The equations are
y = 2x - 3 ------(1)
y = -8x + 17 ----(2)
The y variable has a coefficient of 1 in both equations so we can start with either of equation (1) or (2).
From equation (1) y = 2x - 3. Substitute for the value of y into equation (2)
2x - 3 = -8x + 17
By collecting like terms we now have
2x + 8x = 17 + 3
(Remember that when a negative value crosses to the other side of the equation it becomes positive and vice versa)
10x = 20
Divide both sides of the equation by 10
x = 2
Having calculated the value of x, we can now substitute for the value of x into equation (1)
y = 2x - 3
y = 2(2) - 3
y = 4 - 3
y = 1
Therefore, x = 2 and y = 1.

$6.03
$8.21
$8.56
$11.71
Answer:
$6.03
Step-by-step explanation:
Let the amout Travis spent on pizza be reapresented as A.
Travis bought a sticker for $2.53,
Belt = $5.68
Pizza = ?
Total amount of money spent = $14.24
To get the amount spent on pizza , add up amount of everything he bought and equate them to total amount spent
That’s
$2.53 + $5.68 + A = $14.24
$8.21 + A = $14.24
Subtract $8.21 from both sides
$8.21 - $8.21 + A = $14.24 - $8.21
A = $6.03
Travis spent $6.03 on the pizza
