Answer:
$21.9 per gram
Step-by-step explanation:
Take the total price and divide by the number of grams
$162.18/7.4 grams
$21.91621 per gram
Rounding to the nearest tenth
$21.9 per gram
Answer:
$21.90 per gram (to the nearest tenth)
Step-by-step explanation:
Given information:
Weight of gold necklace = 7.4 gPrice of gold necklace = $162.18To find how much the necklace was worth per gram, divide the total cost by the number of grams:
[tex]\sf Worth\:per\:gram = \dfrac{\$162.18}{7.4\:g}=\$21.91621622... \:per\:gram[/tex]
Therefore, the necklace is worth $21.90 per gram (to the nearest tenth).

a plane intersects the coordinate axes at the point (2,0,0), (0,3,0) and (0.0.4) the obteined point is ax+by+cz+d, find value of d
Answer:
d = 12
Step-by-step explanation:
In intercept form, the equation of the plane is ...
x/a +y/b +z/c = 1 . . . . . for x, y, z intercepts a, b, c
You have (a, b, c) = (2, 3, 4), so the equation of the plane is ...
x/2 +y/3 +z/4 = 1
Multiplying by 12 gets rid of the fractions and puts the equation in standard form:
6a +4y +3z = 12
The value of d is 12.

There are 40 students in your class of which 23 are boys. What fraction of the students are girls?
Answer:17/23
Step-by-step explanation:
Answer: 17/40 of the students are girls.
Step-by-step explanation:
First, to find the number of girls in the class, we can subtract the number of boys (23) from the total number of students (40) to get:
40 - 23 = 17
There are 17 girls in the class.
Finally, to get the fraction of the girl students of the class, we can divide the number of girls (17) by the total number of students (40) to get:
17 ÷ 40 = [tex]\frac{17}{40}[/tex]
Since the fraction [tex]\frac{17}{40}[/tex] is already simplified, the final answer comes out to be [tex]\frac{17}{40}[/tex].
The value of a share of stock on the stock market decreased by 14%. If it used to be worth $102.64, what is it worth now? Round to the nearest hundredth.
Answer:
Step-by-step explanation:
The share of stock is $88.33 worth now which is the value of a share of stock on the stock market decreased by 14%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.
The value of a share of stock on the stock market decreased by 14%. If it used to be worth $102.64 which is given in the question.
We have to determine the evaluation of 15% of 60.
⇒ 14% of $102.64
15% is expressed as 15/100 in fractional form
⇒ (14/100)(102.64)
15/100 is expressed as 0.15 in decimal form
⇒ (0.14)(102.64)
Apply the multiplication operation, and we get
⇒ 14.31
Therefore, 14% of $102.64 would be $14.31.
The share of stock is worth now: $102.64 - $14.31 = $88.33.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is

A taxi is travelling in a circlar path of radius 700 m at the rate of 11 km per hour . Find the angle through which it turns in one minute in grade.
Answer:
Approximately [tex]\text{$0.26$ radian}[/tex] every minute.
Step-by-step explanation:
Convert the unit of velocity (kilometers-per-hour) to meters-per-minute so as to match the unit of radius (meters) and angular velocity (per-minute.)
[tex]\begin{aligned}v &= 11\; \rm km \cdot h^{-1} \\ &= 11 \times \frac{1000\; \rm m}{1\; \rm km} \times \frac{1\; \rm h}{60\; \text{minute}} \\ &\approx 183.33\; {\rm m} \cdot\text{minute}^{-1}\end{aligned}[/tex].
Calculate the circumference of this circle:
[tex]\begin{aligned}c &= 2\,\pi\, r \\ &= 2 \, \pi \times 700\; \rm m \\ &\approx 4398.2\; \rm m\end{aligned}[/tex].
Find the time required (in minutes) for this vehicle to go around this circle:
[tex]\begin{aligned}\frac{4398.2\; \rm m}{183.33\; {\rm m} \cdot \text{minute}^{-1}} \approx 23.990\; \text{minute}\end{aligned}[/tex].
A full circle corresponds to an angle of [tex]2\, \pi \; \text{radian}[/tex] ([tex]360^{\circ}[/tex].) In other words, this vehicle would have turned [tex]2\, \pi \; \text{radian}\![/tex] in approximately [tex]23.990\; \text{minute}[/tex] if it travels at a constant speed. The rate at which this vehicle turn would be:
[tex]\begin{aligned}\frac{2\, \pi}{23.990\; \text{minute}} \approx 0.26\; \text{minute}^{-1}\end{aligned}[/tex].
In general, for angular velocity [tex]\omega[/tex], radius [tex]r[/tex], and velocity [tex]v[/tex], [tex]v = \omega\, r[/tex]. After updating the units, the angular velocity of this vehicle (the rate at which it turns) may also be found as:
[tex]\begin{aligned}\omega &= \frac{v}{r} \\ &\approx \frac{183.33\; \rm m \cdot \text{minute}^{-1}}{700\; \rm m} \\ &\approx 0.26\; \text{minute}^{-1}\end{aligned}[/tex].
Morgan Office Supply sells 8 reams of Brand X paper for $40 and 4 reams of Brand Y paper for $19. What is the cost savings per ream of paper for the cheapest brand?
Answer:
$0.25 per ream
Step-by-step explanation:
The costs per ream are ...
X: $40/(8 reams) = $5/ream
Y: $19/(4 reams) = $4.75/ream
The savings per ream is $5.00 -4.75 = $0.25 for the cheapest brand.

59) Two times a number added to another number is 25. Three times the first number minus the other number is 20.
Find the two numbers.
[tex]\huge \bf༆ Answer ༄[/tex]
Let the first number be x and second one be y !
Here's the Expressions representing the above scenario ~
[tex] \sf2x + y = 25[/tex][tex] \sf3x - y = 20[/tex]If we add these two equations we will get ~
[tex] \sf2x + y + 3x - y = 25 + 20[/tex][tex] \sf5x = 45[/tex][tex] \sf x= 45 \div 5[/tex][tex] \sf x = 9[/tex]Now, plug the value of x in first equation ~
[tex] \sf2x + y = 25[/tex][tex] \sf(2 \times 9) + y = 25[/tex][tex] \sf18 + y = 25[/tex][tex] \sf y = 25 - 18[/tex][tex] \sf y = 7[/tex]Therefore, the first number is x = 9 and the second number is y = 7
