Answer:
Marina's design uses more cardboard.
in Kristen's design, it uses:
3*4/2*2+10*5+3*10+4*10=132 sq inches.
in Marina's design, it uses:
6*3*2+3*7*2+7*6*2=162 sq inches.
132<162
Therefore Marina's design uses more cardboard.
The difference between 2 designs are:
162-132
=30 sq inches

Graph the values where the x -axis shows the number of dimes and the y- axis shows the paring time.
Answer:
it is a 1-10
Step-by-step explanation:
okay so let's say Luke puts in two dimes he gets 20mins of parking so when doing a table put a zero at the end of number of dimes and you get p
for the graph the slope is 1/10 for every dime you go up one and over 10 times

⇒ x² - 9x + 14
Now, We can find the factor of the expression as;
⇒ x² - 9x + 14
⇒ x² - 7x - 2x + 14
⇒ x (x - 7) - 2 (x - 7)
⇒ (x - 7) (x - 2)
Thus, The factor of the equation x² - 9x + 14 is,

The minimum number of times Johnny needs to use the wheelbarrow until the delivery truck is 70% filled, obtained from the volume of the wheelbarrow and the volume of the truck is about 41 times.
What is the volume of a solid?The volume of a solid is the three dimensional space the solid occupies.
The specified dimensions of the wheelbarrow and truck indicates that the volumes of the wheelbarrow and the truck are;
Volume of the wheelbarrow = 2 ft × 1.5 ft × 3 ft = 9 ft³
Volume of the truck = 11 ft × 8 ft × 6 ft = 528 ft³
70% of the volume of the truck = 70% × 528 ft³ = 369.6 ft³
The number of times Johnny uses the wheelbarrow = 369.6 ft³ ÷ 9 ft³ ≈ 41.0
The number of times Johnny needs to use the wheelbarrow is about 41 times

G Carla, Brenda, Marci, Susan
H Carla, Marci, Brenda, Susan
J Susan Marci Brenda. Carla
Answer:
G. Carla, Brenda, Marci, Susan
Step-by-step explanation:
The time given for all participants are in decimals except for that of Marci and Carla which are given in the form of mixed fractions.
Convert the mixed fractions into decimals, then compare the figures together to do the ranking.
Marci = \( 46\frac{49}{50} = \frac{2,349}{50} = 46.98 \)
Carla = \( 46\frac{9}{10} = \frac{469}{10} = 46.9 \)
The first four finishers from the 1st to the 4th are:
1. Carla - 46.9
2. Brenda - 46.97
3. Marci - 46.98
4. Susan - 47.21

A ramp 35 ft long rises to a platform. The bottom of the platform is 18 ft from the foot of the ramp. Find x, the angle of elevation of the ramp. Round your answer to the nearest tenth of a degree. (PLZ HELP I NEED HELP!)
Answer:
\(x\approx 59.1^\circ\)
Step-by-step explanation:
Since we want to find x and we are given the hypotenuse and the side adjacent to x, we can use the cosine ratio:
\(\displaystyle \cos x=\frac{\text{adjacent}}{\text{hypotenuse}}\)
The adjacent side is 18 and the hypotenuse is 35. Substitute:
\(\displaystyle \cos x=\frac{18}{35}\)
Take the inverse cosine both sides. Use a calculator (make sure you're in Degrees mode!). Hence:
\(\displaystyle x=\cos^{-1}\frac{18}{35}\approx59.1^\circ\)

Puteți determina LCM de 12 și 16 folosind două metode
Step-by-step explanation:
F(x)= 1/x-2 g(x)= 4/x find (fog)(x)
We have the functions f and g:
f(x) = 1/x - 2
g(x) = 4/x
To obtain the composite function (f o g)(x):
(f o g)(x) = f(g(x)) = 1/g(x) - 2
Then:
(f o g)(x) = 1/(4/x) - 2
(f o g)(x) = x/4 - 2
Now, to calculate the composite function (g o f)(x):
(g o f)(x) = g(f(x)) = 4/f(x)
(g o f)(x) = 4/(1/x - 2) = 4/((1 - 2x)/x)
(g o f)(x) = 4x/(1 - 2x)

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
f ( x ) = ( x + 2 )²( x -3 ) be equation (1)
Now , on simplifying the equation , we get
f ( x ) = ( x + 2 )²( x -3 )
f ( x ) = ( x² + 4x + 4 ) ( x - 3 )
Now , multiplying each term with ( x - 3 ) , we get
f ( x ) = ( x - 3 ) x² + ( x - 3 ) 4x + ( x - 3 ) 4
f ( x ) = x³ - 3x² + 4x² - 12x + 4x - 12
On simplifying the equation ,we get
f ( x ) = x³ + x² - 8x - 12
Now , the value of the equation f ( x ) = x³ + x² - 8x - 12
On graphing the equation , we get

1) AB + BC = AC
Length of BC = |6 - 1|
2) ∠JMK = 50°
∠KML = 35°
How to Interpret Number Line intervals?
1) From the given number line interval, we can deduce the interpretation as follows;
AB + BC = AC
Length of BC = 5 units or |6 - 1|
Length of B = 3 Units
2) We can see that ∠JML is an angle triangle. Thus, ∠JML = 85°. Thus;
6x + 2 + 4x + 3 = 85
10x + 5 = 85
10x = 85 - 5
10x = 80
x = 80/10
x = 8°
Thus;
∠JMK = 6(8) + 2

What is the 24th term of -21, -14,-7,0,7,…
Answer:
140
If that's wrong, try 147
Step-by-step explanation:
With this brief sequence of numbers, we can see that the function is linear, and increases by 7 each term, with the first term at -21, and therefore, the "0th" term, or the y-intercept, at -28. With this information we can create a function in slope intercept form (y=mx+b):
\(y=7x-28\\\),
where our m (slope) is 7, and our b (y-intercept) is -28.
If this doesn't make sense, then the easiest way is to just keep adding seven to the previous number until you get to the 24th term.

Georgie spends $160 on clothes. She pays 6.5% in tax. How much does she spend altogether?
The correct answer is $170.4
Explanation:
The total Georgie spent is equal to the money spent on clothes ($160) added to taxes (6.5% of the price of the clothes). Now, to calculate the money spend on taxes follow this process:
1. Divide the total of money spent on clothes into 100 (this number represents 100%)
160 ÷ 100 = 1.6
2. Multiply this number by the specific percentage (6.5)
1.6 x 6.5 = $10.4 (This is the money spent on taxes)
Finally, add the value of taxes and the price of the clothes:
$160 + $10.4 = $170.4
