At the school carnival, the sixth graders are making directional arrows, as shown below. Each arrow needs to be painted red. How much area needs to be painted for one arrow?
Dimensions:
6
10
8
4​

Answer:

Step-by-step explanation:

1. As you can see in the picture, x is 116 degrees, because that angle and the angle labeled 116 degrees are corresponding, meaning that their angles are the same.  

2. As you can also see in the picture, y+11+x = 180 deg, because they are two angles that make a straight angle. We know that x is 116 deg, so we can solve y with an equation:

y + 11 + 116 = 180

y + 127 = 180

y = 180 - 127

y = 53 degrees.

Answer:

34.5%

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 9, \sigma = 2.5[/tex]

What percentage of the books last more than 10 years?

As a proportion, this is 1 subtracted by the pvalue of Z when X = 10. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{10 - 9}{2.5}[/tex]

[tex]Z = 0.4[/tex]

[tex]Z = 0.4[/tex] has a pvalue of 0.655

1 - 0.655 = 0.345

So

34.5% of the books last more than 10 years.

x =√-1.403 = 0.0 - 1.18454 i

x =√-1.403 = 0.0 + 1.18454 i

x =√11.403 = -3.37685

x =√11.403 = 3.37685

Answer:

B:25°

Step-by-step explanation:

Now [tex]\angle ABC[/tex] gets bisected by [tex]BD[/tex].

[tex]\angle ABD=25^{\circ}[/tex]

Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.

We know that one of the angles is [tex]25^{\circ}[/tex] so the other angle has to be [tex]25^{\circ}[/tex] also.

Hence, the [tex]m\angle DBC=25^{\circ}[/tex].

Step-by-step explanation:

The algebraic expression is

(x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)

The options are                                               Arrangement

a.(x+5/x+2) * ( x+2/x+5)                                             Number 2

b.(x+7/x+4) ( x+1/x+2)

c.    1                                                                            Number 4

d.   (x+5) ( x+2) /(x+5)

e.  (x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2)

f. (x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)       Number 1

g. x+2

h.(x+5/x+2) ( x+2/x+5)                                               Number 3

Answer

Factorizing the expressions (x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)

=(x²+ 5x+2x+ 10/ x²+ 2x+2x+4 ) (x²+ 2x+x+ 2/x²+ 5x+x+5)

Taking common

=[x(x+5) +2(x+5)/ x(x+2) +2(x+2) ] [ x(x+2) +1(x+2)/ x((x+5) +1(x+5)]

Putting commons together

=[(x+2) (x+5)/ (x+2) (x+2)] [ (x+2)(x+1)/ (x+1) (x+5)]

Cancelling

= [ (x+5)/ (x+2)]* [ (x+2)/  (x+5)]

=[ (x+5)/ (x+2)] [ (x+2)/  (x+5)]

Again Cancelling

=1

The above question is solved in 4 steps :

Step 1

(x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)

Step 2

(x+5/x+2) * ( x+2/x+5)

Step 3

(x+5/x+2)  ( x+2/x+5)

Step 4

1   which is the answer .

The steps

(x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2) ,

(x+5) ( x+2) /(x+5),  

(x+7/x+4) ( x+1/x+2) and (x+2) are not related to this question.

Answer:

The probability is ⁹/₆₄

Step-by-step explanation:

Given;

number of red marbles, R = 3

number of green marbles, G = 5

Total number of marbles, T = 8

The probability of choosing two red marbles in a row with replacement;

[tex]P(2 R) = P(R_1 \ n \ R_2)\\\\P(2 R) = \frac{3}{8} \ \times \ \frac{3}{8} \\\\P(2 R) = \frac{9}{64}[/tex]

Therefore, the probability of choosing two red marbles in a row with replacement is ⁹/₆₄

Answer:

Answer is explained below in the explanation section.

Step-by-step explanation:

Solution:

For this question, we need to have a number line, we can not make the number line here. As it will be very long. Instead, I have attached a number line from -11 to +11 for your understanding and explained it below. Please refer to the attachment below for the number line.

Number Line:

A number line is a line which contains all the numbers from negative infinity to positive infinity divided by a single number zero. It has two sides, left hand side and right hand side. A side left to zero contains all the negative numbers and a side right to 0 contains, all the positive numbers.

So,

We are asked to add 34 in (-212), we will get 178 but with the negative sign, and it will lie on the left hand side of the number line.

SO,

34 + (-212) = 34 - 212 = -178

Hence,

Our sum which is 178 will lie on the left hand side of the number line.

Step-by-step explanation:

For 10 flapjacks we need a total of 100g of ingredients

therefore, we need to get how many gram for 1 flapjacks

that is, for butter 20÷10=2

for sugar 30÷10=3

for rolled oats 50÷10=5

that's a total of 10.

this means it takes 10g of ingredients to make 1 flapjacks

then 140+150+200=490

490÷10=49

The final answer is 49 flapjacks can be made from the above ingredients

This question is incomplete; here is the complete question.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.

If it continues to fall at this rate, what will the temperature be:

In 2 hours ............. In 5 hours .............. In half an hour......................

If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.

Then after 'x' hours, temperature on the top of the mountain will be represented by the function,

T(x) = 0 - 3x

Therefore, temperature after 2 hours = -3(2) = -6°C

Temperature after 5 hours = -3(5) = -15°C

Temperature after half an hour = [tex]-3(\frac{1}{2})[/tex]

                                                    = -1.5°C
