789845 rounded up to thousand would be 790000 because 845 is close to 1000 so it's counted as a 1000

so 789000 + 1000 = 790000

I NEED HELPPP<br><br> Whats the length of LN?

andre [41]

Answer:

LN = 66 cm

Step-by-step explanation:

The 3 parallel lines divide the 2 sides they intersect in proportion, that is

$\frac{DE}{EF}$ = $\frac{LM}{MN}$ , substitute values

$\frac{7}{15}$ = $\frac{LM}{45}$ ( cross- multiply )

15LM = 315 ( divide both sides by 15 )

LM = 21

Hence

LN = LM + MN = 21 + 45 = 66 cm

Given sin theta= 6/11 and sec theta < 0, find cos theta and tan theta.

bekas [8.4K]

Answer: option a.

Step-by-step explanation:

By definition, we know that:

$cos^2(\theta)=1-sen^2(\theta)\\\\tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

Substitute $sin(\theta)=\frac{6}{11}$ into the first equation, solve for the cosine and simplify. Then, you obtain:

$cos(\theta)=\±\sqrt{1-(\frac{6}{11})^2}\\\\cos(\theta)=\±\sqrt{\frac{85}{121}}\\\\ cos(\theta)=\±\frac{\sqrt{85}}{11}$

As $sec\theta$ then $cos\theta$ :

$cos(\theta)=-\frac{\sqrt{85}}{11}$

Now we can find $tan\theta$ :

$tan\theta=\frac{\frac{6}{11}}{-\frac{\sqrt{85}}{11}}\\\\tan\theta=-\frac{6\sqrt{85}}{85}$

the concrete slab under a garage measures 38 feet by 37 feet and is 6 inches thick. if concrete costs 150$ for a cubic yard, how

Natalka [10]

STEP 1
find cubic feet; multiply the three dimensions together; be sure to use the same unit of measure for all three dimensions: 6 inches is equal to 1/2'.

= 38' * 37' * 1/2'
multiply

= 703 cubic feet

STEP 2
divide cubic feet in step 1 by number of cubic feet in a cubic yard

27 cubic feet= 1 cubic yard

= 703 ÷ 27
= 26.037 cubic yards

STEP 3
multiply cubic yards in step 2 by cost per cubic yard

= 26.037 * $150
= $3,905.555
= $3,906 rounded to nearest dollar

ANSWER: It will cost $3,906 (rounded to nearest dollar).

Hope this helps! :)
