Janey paints a block of wood with gold glitter for an art project. The block measures 8 inches by 10 inches by 20 inches. After she's done, she decides to make two blocks by cutting through the block on the red line. She still wants each block to be covered with gold glitter
1. what is the shape of each cut surface? What are its dimensions? and what is the total area of paint she still needs to paint?
2. What is the area of each cut surface?
Answer:
1. Square, 10in x 8in, 160in^2
2. Each surface has an area of 80in^2
Step-by-step explanation:
1. Rectangle is the shape of each cut surface which is 10in by 8 in. Since the block was already painted with glitter, she needs to paint both sides of the cut surface only, 2*8in * 10in = 160in^2.
2. Each cut will have a surface area of 10in * 8in = 80in^2

5. Claude is wrapping cylindrical bug spray containers in tissue paper to put them inside a box.
Each container has a height of 12.7 centimeters and a radius of 3 centimeters.
If he is wrapping a total of 5 bug spray containers, how many square
centimeters of tissue paper will he need?
Answer:
[tex]1197.42\ cm^2[/tex]
Step-by-step explanation:
Given that,
The height of cylinder, h = 12.7 cm
The radius of the cylinder, r = 3 cm
The curved surface area of a cylinder for 5 bug spray is given by :
[tex]C=5\times 2\pi rh\\\\C=10\times \dfrac{22}{7}\times 3\times 12.7\\\\C=1197.42\ cm^2[/tex]
So, [tex]1197.42\ cm^2[/tex] of tissue papers will be needed.

Trigonometry question
Answer:
The answer would be 6.8 I believe.
Step-by-step explanation:
Step 1: You would have to find which side is the opposite , hypotenuse and adjacent to the degree. 8 is adjacent and x is the hypotenuse. Then you can use a strategy I like which is called SOH CAH TOA to find if you need to use sin, cosine, or tangent. It tells you in the acronym too how to set up the equation.
Step 2: In this case we need cosine since it is adjacent over hypotenuse (C in the acronym is for cosine A is for adjacent and H is for hypotenuse) so the equation would be Cos32= 8/x
Step 3: Then solve the equation, so you would do
8cos32=x
Put that into the calculator (I'm using a TI-84) and make sure it is in degree mode and you would get 6.78 but round that up to 6.8.
I hope this helps and that I did it right!!
[tex] log_{2}(x) = - 4[/tex]
WILL GIVE BRANIEST FOR LEGIT ANSWERS WITH WORK
Answer: x = 1/16
Step-by-step explanation:
Since the inverse of a Logarithm is an exponential function, we know that the final solution has to involve an exponential function somewhere in it.
1. log B(2) {x} = -4 || given
2. x = 2 ^ -4 || Logarithm rule that allows you to move the base of the logarithm to the base of the exponent on the other side. For example, if you had log B(5) {x} = 3, the base of 5 would move over to the other side and it would be raised to 3; x = 5^3.
3. x = (1) / (2^4) || Simplify. Use the negative exponent rule. This rule always leaves a numerator of 1, and a denominator of your exponent. In this case, it will be 2 ^ -4, so you will do 2^4 which is 16 and you will put that over 1. Resulting in your final answer of x = 1/16

How do I simplify 55/35
Answer:
1 4/7
Find a number that will divide evenly into both the top number and the bottom number. (You can do any math operation to either number as long as you do the same to the bottom number.)
Keep doing that until you can't find a number that works.
In this case try 5.
55 ÷ 5 = 11 and 35 ÷ 5 = 7
so: 55/35 = 11/7
since the top number is greater than the bottom, reduce 11/7 to 1 4/7
Answer:
[tex] \frac{55}{35} \\ \frac{11}{7} \\ 1.57[/tex]

what is the circumference of a circle with a diameter of 23.4 inches?
please hellp
Answer:
Step-by-step explanation:
Circumference = 73.51
Hope this helps :)
Answer:
Assuming that [tex]\pi[/tex] is equivalent to 3.14, the circumference of the circle is 73.476 inches.
Step-by-step explanation:
The formula for the circumference of a circle is [tex]2\pi r[/tex], or the diameter of a circle multiplied by [tex]\pi[/tex]. Because the diameter is 23.4, that means the circumference would be 23.4 * 3.14 = 73.476 inches.

Find the Z-scores that separate the middle 61% of the distribution from the area in the tails of the standard normal distribution
Answer:
Z-scores between -0.86 and 0.86 separate the middle 61% of the distribution from the area in the tails of the standard normal distribution
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set 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]
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Middle 61%
Between the 50 - (61/2) = 19.5th percentile and the 50 + (61/2) = 80.5th percentile.
19.5th percentile.
Z with a pvalue of 0.195. So Z = -0.86
80.5th percentile.
Z with a pvalue of 0.805. So Z = 0.86.
Z-scores between -0.86 and 0.86 separate the middle 61% of the distribution from the area in the tails of the standard normal distribution
