Determine the value of x.

Mathematics
1 answer:
Lemur [1.5K]3 years ago
6 0

Answer:

10 sqrt(3)/3 =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side /adj side

tan 30 = x/10

10 tan 30 =x

10 ( sqrt(3)/3) = x

10 sqrt(3)/3 =x

What is the slope y+2=1/4(x-3)
ioda

Answer:

m=\frac{1}{4}

Step-by-step explanation:

Given

y+2=\frac{1}{4}(x-3)

Required

Find the slope

y+2=\frac{1}{4}(x-3)

Subtract 2 from both sides

y+2-2=\frac{1}{4}(x-3) - 2

y=\frac{1}{4}(x-3) - 2

Open bracket

y=\frac{1}{4}x-\frac{1}{4}*3 - 2

y=\frac{1}{4}x-\frac{3}{4} - 2

Take LCM

y=\frac{1}{4}x+\frac{-3 - 8}{4}

y=\frac{1}{4}x+\frac{-11}{4}

y=\frac{1}{4}x-\frac{11}{4}

An equation has the form:

y = mx + b

Where

m = slope

By comparing: y = mx + b and y=\frac{1}{4}x-\frac{11}{4}

m=\frac{1}{4}

<em>So, the slope is 1/4</em>

How much fabric is needed to create the lateral faces of the tent?
jek_recluse [69]
Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40

40+89.6=129.6

the area of the bottom is 7*8=56

the total area is 129.6+56=185.6

I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice. 
I'd suggest 185.6, the total surface area.

A rectangle has a volume of 912 cubic meters. It has a length of 19 meters and a width of 12 meters. Which equation can be used
Nimfa-mama [501]
The answer would be B because LWH=V, so taking the information given, L(19) times W(12) would equal 228 and 228 times the H would give us volume so B
Hope this helped ;)

In ∆TUV, Y is the centroid. If TW = 30, what is YW?
nasty-shy [4]
The complete question in the attached figure

we know that
t<span>he centroid is always 2/3 the distance of each median to each vertex
TW=30
TW=TY+YW
TY=(2/3)*30---------> TY=20
then
YW=TW-TY-----------> YW=30-20-----------> YW=10

the answer is 
YW=10</span>

In a prior sample of corn, farmer Carl finds that 14% of the sample has worms but the margin of error for his population estimat
Savatey [412]

Answer: 741

Step-by-step explanation:

As per given ,we have

The prior estimate of population proportion: p=0.14

Margin or error : 2.5%=0.025

Critical value for 95% confidence = z_{\alpha/2}=1.96

Formula to find the sample size :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

i.e. n=0.14(1-0.14)(\dfrac{1.96}{0.025})^2

=740.045824\approx741

Hence, the minimum sample size required to obtain this type of accuracy= 741
