Cara leaves her house at 10:03 and arrives at the library at 10:17. Irena leaves her house at 11:55 and arrives at the library at 12:06. Who takes longer to get to the library? How many minutes longer? Blank takes longer. She takes blank minutes longer
Answer: Cara takes longer to get to the library. She used 3 minutes more
Step-by-step explanation:
Cara leaves her house at 10:03 and arrives at the library at 10:17. The number of minutes used by Cara will be:
= 10.17 - 10.03
= 14 minutes
Irena leaves her house at 11:55 and arrives at the library at 12:06. The number of minutes used by Irena will be:
= 12.06 - 11.55
= 11 minutes
Cara takes longer to get to the library. She used (14 - 11) = 3 minutes more

Because we are reflecting across the X-axis, the X coordinate does not change. On the other hand, the Y coordinate becomes its opposite. So we get:

Answer:
I believe the answer is B
Step-by-step explanation:
When a plant or animal dies, it stops acquiring carbon-14 from the atmosphere. The amount y (in grams) of carbon-14 in the body of an
organism after t years is y = a(0.5)
t/5730
where a is the initial amount (in grams). What percent of the carbon-14 is released each year? Round
your answer to the nearest hundredth.
his
about
%
Answer:
0.01 %
Step-by-step explanation:
The given model is;
y = a (0.5)^t/5730
Which is;
y = a(2^-1(t/5730)
Then;
y = a (2^-1/5730)^t
y = a(0.999879)^t
Hence;
Given that the general model is;
y(x)= a(1-r)^x
Where r is the rate percent
Since 1-r =0.999879
r = 0.00012096
y = a(1 - 0.00012096)^t
So;
r= 0.00012096* 100 = 0.01 %

Answer:
38°
Step-by-step explanation:
The angles in a triangle always add up to 180 degrees.
Therefore, all the angles in the triangle given in the question add up to 180 degrees.
So, let's create an equation and solve for [tex]x[/tex]:
[tex]x+44 + 63 + 85 + x = 180[/tex]
Simplify:
[tex]2x + 192=180[/tex]
Solving for [tex]x[/tex] we get:
[tex]2x=-12\\x=-6[/tex]
Now, let's put the value of [tex]x[/tex] we got into the formula for angle A.
[tex]x+44=y[/tex]
[tex]-6+44=y=38[/tex]

8 congruent spheres are packed into a cube with
edge length x so that each sphere is tangent to 3
faces of the cube and 3 other spheres as shown.
what is the ratio of the total volume of the
spheres of the volume of the cube?
Answer:
Ratio of the volumes of the spheres and cube = 0.523
Step-by-step explanation:
From the figure attached,
Diameter of one sphere = Half of the measure of one side of the cube
= [tex]\frac{x}{2}[/tex]
Radius of the sphere = [tex]\frac{\frac{x}{2}}{2}[/tex]
= [tex]\frac{x}{4}[/tex]
Volume of a cube is given by the formula,
V = [tex]\frac{4}{3}\pi r^{3}[/tex]
Therefore, volume of one sphere = [tex]\frac{4}{3}\pi (\frac{x}{4})^{3}[/tex]
= [tex]\frac{x^3\pi}{48}[/tex]
Volume of 8 spheres = [tex]8\times \frac{x^3\pi}{48}[/tex]
= [tex]\frac{x^3\pi}{6}[/tex]
Volume of a cube = (side)³
= [tex]x^3[/tex]
Ratio of the volumes of the sphere and cube = [tex]\frac{\frac{\pi x^3}{6} }{x^3}[/tex]
= [tex]\frac{\pi}{6}[/tex]
≈ 0.523
how do you use change of base formula
Answer:
According to the change-of-base formula, we can rewrite the log base 2 as a logarithm of any other base. Since our calculators can evaluate the natural log, we might choose to use the natural logarithm, which is the log base e.

Karen and her friends decided to have a water balloon fight! They got 20 water balloons and used 6 liters of water to fill them all equally. How much water was in each balloon?
Answer:
Amount of water in each balloon = 300 milliliter
Step-by-step explanation:
Given:
Amount of water used in balloon = 6 liter
Number of water balloon = 20 balloon
Find:
Amount of water in each balloon
Computation:
Amount of water used in balloon = 6 x 1000
Amount of water used in balloon = 6,000 milliliter
Amount of water in each balloon = Amount of water used in balloon / Number of water balloon
Amount of water in each balloon = 6,000 / 20
Amount of water in each balloon = 300 milliliter
Paragraph Finding the part, percent, and the whole Styles 1) Sixteen students in the school band play clarinet. Clarinet players make up 20 %v of the band. How many students are in the school band?
Answer:
80
Step-by-step explanation:
You know that 20% of the school band are 16 clarinet players, or 16 is 20% of the band.
You can set up the equation 0.2x = 16 and divide both sides by 0.2. You then get that x = 80, so there are 80 kids in the school band.

Heyaa!! Im Pinky!! And Im Here To Inform You That Your Answer Is...
Step-by-step explanation:
!!!! A. 3/8 !!!!
My calculations:
Given
2/3 y = 1/4
Multiply Each Sides by 3!
2y = 3 × 1/4= 3/4
Then we can Divide both sides by 2!
y= 3/4 ÷ 2 = 3/4 × 1/2 = 3/8!!

Two triangles are congruent if one angle of one triangle is equal in measure to the corresponding angle of the other triangle.
True or False
Answer true
Step-by-step explanation:
Answer:
Correct option is
False
Even though all the corresponding angles of the two triangles are equal, the corresponding sides may not be equal.
Hence, the two triangles are not congruent.
The given statement is false.

The image of the hexagon is missing, so i have attached it.
Answer:
∠1 = 36°
Step-by-step explanation:
From the image attached, we can see that the polygon is regular and has 10 sides.
Formula for an interior angle of a regular polygon is;
θ = 180(n - 2)/n
Where n is the number of sides of the polygon.
Thus;
θ = 180(10 - 2)/10
θ = 144°
Now, ∠1 forms a straight line with one of the interior angles of the polygon.
Thus, θ + ∠1 will be equal to 180° because sum of angle on a straight line is 180°
Thus;
144° + ∠1 = 180°
∠1 = 180° - 144°
∠1 = 36°
The tile showen are placed in a bag you randomly select one of the tiles return it to the bag and randomly selecting Lo tile what is the probability that the first number divided by the second number is greater than zero
Answer:
15
Step-by-step explanation:
The probability that the first number divided by the second number is greater than zero is 1/3
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Tiles are numbered -2,-1,1,2
So, possibility first number divided by the second number is greater than zero
-2/-1=2
-2/1=-2
-2/2=-1
-1/-2= 0.5
-1/1=-1
-1/2=-0.5
1/-2=-0.5
1/-1=-1
1/2=0.5
2/-2=-1
2/-1=-2
2/2=1
Probability the first number divided by the second number is greater than zero = 4/12=1/3.

Malaya is standing directly between a 90-foot tall courthouse and a 54-foot tall bank. If the angle of elevation from the point where Malaya is standing to the top of the courthouse is 72°, while the angle of elevation to the top of the bank is 35°. What is the distance between the courthouse and the bank?
Answer:
Step-by-step explanation:
Draw a picture.
c and b are Malaya’s distance from the courthouse and bank, respectively.
tan(72°) = c/90
c = 90tan(72°)
tan(35°) = b/54
b = 54tan(35°)
Distance between courthouse and bank = c+b
= 90tan(72°) + 54tan(35°)
= 301.5 ft
