Let p be the number of pens in container. If there are 9 more pencils than pens, then there are p+9 pencils in container.

In total, there are p+p+9=2p+9 utensils in the container.

You know that there are 25 writing utensils in the container in all, thus

2p+9=25.

Answer: correct option is D.

The length of a rope is 21 3/8 feet. James cut 2 3/4 feet from this length of rope to use on a project. What length of rope is r

Nookie1986 [14]

Answer:

18 15/24

Step-by-step explanation:

21 3/8 is equal to 21 9/24, which is equal to 20 33/24 and 2 3/4 is equal to 2 18/24. When you subtract 20 33/24 and 2 18/24, the difference is 18 15/24. The length of rope remained unused is 18 15/24 feet.

VARVARA [1.3K]

Answer:

The answer is " $\bold{\frac{11}{3}}\\\\$ ".

Step-by-step explanation:

Given value:

i) (2010,48) and (2013,59)

ii) (0,48) and (3,59)

Slope for the given point:

Formula:

$\bold{M= \frac{y_2-y_1}{x_2-x_1}}$

In point (i):

$\to M= \frac{59-48}{2013-2010}\\\\$

$= \frac{11}{3}\\\\$

In point (ii):

$\to M= \frac{59-48}{3-0}\\\\$

$= \frac{11}{3}\\\\$

Find f(-2) if f(x) = x + x + 7. f(-2) =

viktelen [127]

Answer:

f(-2) = 3

Step-by-step explanation:

Given that,

f(x) = x + x + 7

We need to find the value of f(-2).

Put x = -2 in the given function.

f(-2) = (-2) + (-2) + 7

= -2-2+7

= -4+7

= 3

Hence, the value of f(-2) is equal to 3.

Can anyone do 4,5 and 6 for me plz

For question 4, $sinA =\frac{a}{c}, cosA= \frac{b}{c}, tan B = \frac{b}{a}, sin J = \frac{j}{l}, cosK = \frac{j}{l}, tanK = \frac{k}{j}.$

Question 5. Option a and question 6. Option j

Step-by-step explanation:

Step 1:

The three basic formula needed to solve these questions are:

$sin\theta = \frac{oppositeside}{hypotenuse} , cos\theta = \frac{adjacentside}{hypotenuse}, tan\theta= \frac{opposite side}{adjacent side}.$

Step 2:

Using the above formula, we solve the following values

$sinA = \frac{oppositeside}{hypotenuse}$ $=\frac{a}{c}.$

$cosA = \frac{adjacentside}{hypotenuse}$ $= \frac{b}{c}.$

$tanB= \frac{opposite side}{adjacent side}$ $= \frac{b}{a}.$

$sinJ = \frac{oppositeside}{hypotenuse}$ $= \frac{j}{l}.$

$cosK = \frac{adjacentside}{hypotenuse}$ $= \frac{j}{l}.$

$tanK= \frac{opposite side}{adjacent side}$ $= \frac{k}{j}.$

Step 3:

For question 5, The triangle's angle = 23°, opposite side = BC inches and hypotenuse = 4 inches.

$sin\theta= \frac{opposite side}{hypotenuse}. sin 23^{\circ}= \frac{BC}{4}, sin23^{\circ} = 0.3907,BC = (0.3907)(4) = 1.5628.$

SO BC is 1.5628 inches, rounding this off to the nearest tenth, we get BC = 1.6 inches which is option a.

Step 4:

For question 6, The triangle's angle = 50°, opposite side = QR m the adjacent side = 8.1 m.

$tan\theta= \frac{opposite side}{adjacentside}. tan 50^{\circ}=\frac{QR}{8.1}, tan50^{\circ} = 1.1917,QR = (1.1917)(8.1) = 9.65277$

SO QR is 9.65277 meters, rounding this off to the nearest tenth, we get QR = 9.7 inches which is option j.
