Answer for brainlist with steps

bulgar [2K]

Step-by-step explanation:

2+6x= -10 + 11(x + 4)

2+ 6x = -10 + 11x + 11(4)

2 + 6x = -10 + 11x + 44

2+ 6x = 11x + 34

6x - 11x = 34 - 2

-5x = 32

x= - 32/5

Reduce then calculate 7/8 x 4/15 x 3/7 = ? <br><br> Can you help?

Zepler [3.9K]

since this is a multiplication, all the numerators are just factors of the product numerator and all denominators are just factors of the product denominator, so we can simply reorder them some, without changing the product.

$\bf \cfrac{7}{8}\times \cfrac{4}{15}\times \cfrac{3}{7}\implies \cfrac{7}{7}\times \cfrac{4}{8}\times \cfrac{3}{15}\implies \cfrac{1}{1}\times \cfrac{1}{2}\times \cfrac{1}{5}\implies \cfrac{1\cdot 1\cdot 1}{1\cdot 2\cdot 5}\implies \cfrac{1}{10}$

Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal

cricket20 [7]

Answer:

The arc length of the semicircle is $5 \pi\ units$ or $15.7\ units$

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

$C=\frac{1}{2}\pi D$

where

D is the diameter of the semicircle

we have

$D=10\ units$

substitute

$C=\frac{1}{2}\pi (10)$

$C=5 \pi\ units$ ----> exact value

Assume

$\pi =3.14$

$C=5(3.14)=15.7\ units$ ----> approximate value

therefore

The arc length of the semicircle is $5 \pi\ units$ or $15.7\ units$

Please help!!! I'm super confused with this one, show work so that I can figure out what I did wrong.

Answer: The length of CU is 117 units.

Step-by-step explanation:

Given: ΔWCD≈ΔWUV

We know that if two triangles are similar, then their corresponding sides are proportional.

∴ $\frac{WU}{WC}=\frac{WV}{WD}$

$\frac{36x-1}{26}=\frac{110}{20}\\\Rightarrow\ 36x-1=\frac{11}{2}\times26\\\Rightarrow36x-1=143\\\Rightarrow\ 36x=143+1\\\Rightarrow\ 36x=144\\\Rightarrow\ x=4$

∴ WU= $36(4)-1=143$

Also , WU=WC+CU

⇒CU=WU-WC

⇒CU=143-26=117 units
