melamori03 [73]

Answer:

B = 62.9ft

Step-by-step explanation:

The distance where she is from the oak tree is 75ft,

The angle of elevation the stone makes with the top of the oak tree is 40°

The height of the tree is x ft

See attached document for better illustration

Using SOHCAHTOA,

Tanθ = opposite/ adjacent

θ = 40°

Opposite = x ft

Adjacent = 75ft

Tan40 = x / 75

X = 75 × tan40

X = 75 × 0.8390

X = 62.92ft

The height of the oak tree is 62.9ft

Likurg_2 [28]

Answer: 18

Step-by-step explanation:

The options are:

A. 23

B. 18

C. 14

D. 32

Since we are told that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. This simply means that the ratio of flour tortillas to the total number of packages on the shelf was (16 -7 = 9) 9 to 16.

Therefore, to get the number that could represent the number of packages of flour tortillas the clerk put on the shelf we have to find the multiple of 9 in the question given . This will be:

Multiples of 9 = 9, 18, 27, 36, 45 ....

Based on the option, the answer will be 18.

Adding or subtracting fractions with different denominators

Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

$\frac{1}{2} +\frac{1}{3}$ The LCD is six

$\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}$

$\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}$

$\frac{3+2}{6}= \frac{5}{6}$

Hope this helps, have a BLESSED and wonderful day! :-)
