Dallas made two pies for Thanksgiving in identical pie tins. 3/8 is left of one pie, and 2/3 is left of the other. Will all the leftover pie fit in one pie tin?
answer choices
a. yes, because 3/8 + 2/3 is less than 1
b. yes, because 3/8 is less than 2/3
c. no, because 3/8 + 2/3 is more than 1
d. no, because 2/3 is more than 3/8
3/8 = 0.375
2/3 = 0.667
0.375 + 0.667 = 1.042
answer : c. no, because 3/8 + 2/3 is more than 1
In number 1783429 write the follwings:
i)Write rhe digit that is in the ten thousand place.
ii)Successor of the number
Answer:
i) 8
ii) 9
Step-by-step explanation:
For i):
1 = million
7 = hundred thousand
8 = ten thousand place
3 = thousand
4 = hundred
2 = tens (twenty)
1 = unit (one)
For ii):
The successor of a number is the number that comes after the given number. The successor of a given number is 1 more than the given number. Every number has a successor by adding 1 to every number.
For instance, the successor of 0 is 1, the successor of 1 is 2, and so on.
In this case, the successor of 8 is 9 because 8 + 1 = 9

Calculate the surface area. Be sure to show how the area of each face is calculated.
Answer:
Surface area of the cubiod is 186.34 cm²Step-by-step explanation:
Given:
Shape = cubiodLength of cubiod = 10cmWidth of cubiod = 4.1 cmHeight of cubiod = 3.7 cmTo Find:
Surface areaSolution:
We can find the total surface area of cubiod by summing up the area of the six faces of the cubiod:
Area of the top and bottom face = lw+ lw = 2lwArea of the front and back face = lh+ lh = 2lhArea of the two side faces = wh+ wh = 2whSurface Area = 2(lw+ wh + hl)
Substituting the required values:
➝ Surface Area = 2(10 × 4.1) + (4.1 × 3.7) + (3.7 × 10)
➝ Surface area= 2(41 + 15.17 + 37)
➝ Surface Area = 2(93.17)
➝ Surface Area = 186.34 cm²
Hence,
Surface area of the cubiod is 186.34 cm²Pls help!!!!!!!!!!!!!!!!!!!!!!!
Which angles are not supplementary
===============================================================
Explanation:
Choice a) can be ruled out because angles A and D are supplementary. Supplementary angles add to 180 degrees by definition. They form a straight line or straight angle.
Choice b) and choice d) are eliminated for similar reasoning as choice a).
Choice c) is the only thing left. It turns out that angles B and D are not supplementary, but rather they are vertical angles. They are opposite one another in this X shape. Vertical angles are always congruent.
Note: Angles B and D are supplementary if and only if the angles are 90 degrees each.

The heights of a species of plant are approximately Normally distributed, have a mean of 9.31 cm, and have a standard deviation of 0.55 cm. If 20 of the plants are randomly selected, what is the probability that the mean plant height is less than 9.5 cm?
0.0612
0.6351
0.9388
approximately 1
Using the normal distribution and the central limit theorem, it is found that the probability that the mean plant height is less than 9.5 cm is of 0.9388.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem, the mean and the standard deviation are given, respectively, by [tex]\mu = 9.31, \sigma = 0.55[/tex].
For samples of n = 20, the standard error is given by:
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]s = \frac{0.55}{\sqrt{20}}[/tex]
s = 0.123.
The probability that the mean plant height is less than 9.5 cm is the p-value of Z when X = 9.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{9.5 - 9.31}{0.123}[/tex]
Z = 1.54.
Z = 1.54 has a p-value of 0.9388.
Hence the probability that the mean plant height is less than 9.5 cm is of 0.9388.

The height of the center of the clock above the ground is 52 feet such that the length of the minute hand of the clock is 6 feet and at 10 minutes after the hour, the tip of the minute hand is 55 feet above the ground.
Sine trigonometric functionThe trigonometric function, [tex]sin\theta=\dfrac{perpendicular}{hypotenuse}[/tex] .
How to determine the length of the side using trigonometric function?From the given information, the following pictorial representation can be made.
The distance between the centre of the clock and the the point of the minute hand 10 minutes after the hour is-
[tex]x=6sin30\\x=3\text{ft}[/tex]
Now, from the figure,
The height of the center of the clock above the ground is-
d=6+(55-3-6)
=52 ft
Thus, the height of the center of the clock above the ground is [tex]52\text{ft}[/tex]

How would I solve the equation’s by cross multiplying number 4,5,9,10
Answer:
4) a = 6
5) m = 1
Step-by-step explanation:
4) use FOIL, First Inside Outside Last, when you cross multiply.
[tex]\frac{a+4}{a-1} =\frac{a-2}{a-4}[/tex]
[tex](a+4)(a-4) = (a-1)(a-2)[/tex]
I'm going to do the left side first.
[tex](a+4)(a-4)\\a^2-4a+4a-16\\a^2-16[/tex]
Now I'm going to do the right side.
[tex](a-1)(a-2)\\a^2-2a-1a+2\\a^2-3a+2[/tex]
Next I'm going to rewrite back as the equation and solve for a.
[tex]a^2 - 16 = a^2 -3a +2\\a^2 - a^2 -16 = a^2-a^2-3a+2\\-16-2=-3a+2-2\\-18=-3a\\-18/-3=-3a/-3\\a=6[/tex]
5) I'm going to use distributive propoerty when I cross multiply. Then I will setup an equation like number 4 and solve for m.
[tex]\frac{5m-2}{3}=\frac{8-3m}{5} \\[/tex]
[tex]5(5m-2)=3(8-3m)\\25m-10=24-9m\\25m+9m-10=24-9m+9m\\34m-10=24\\34m-10+10=24+10\\34m=34\\34m/34=34/34\\m=1[/tex]

Step-by-step explanation:
Angles XVW and XYZ are congruent, and so are angles VWX and XZY by the alternate interior angles theorem.
This means that triangle VWX is similar to triangle YZX.
So, since corresponding sides of similar triangles are proportional, VW/XY = WX / XZ.
120/8 = 15 = WX / 6.
So the width is 90 m.
