Answer:

100g : 60g : 80g

Step-by-step explanation:

5+3+4 =12 total parts

(5/12 of 240)

5/12 x 240 = 100g

3/12 x 240 = 60g

4/12 x 240 = 80g

Check:

100g + 60g + 80g = 240g

Answer:

y = 17

17 - 6 is 11, so 17 would be the only number convenient.

Answer:

y = 17!

Step-by-step explanation:

11 + 6 = y - 6 + 6

Answer:

Step-by-step explanation:

Perimeter is sum of all the sides.

Perimeter = 9f + g + 5f + 9h + 2h + 7g

                 = 9f + 5f + g +7g + 9h + 2h   {Combine like terms}

                 =  14f + 8g + 11h

[tex] \frac{1}{15} + \frac{1}{5} + \frac{1}{3} [/tex]

the simplest form.

[tex] \frac{1}{15} + \frac{1 \times 3}{5 \times 3} + \frac{1 \times 5}{3 \times 5} [/tex]

[tex] = \frac{1}{15} + \frac{5}{15} + \frac{3}{15} [/tex]

[tex] = \frac{1 + 3 + 5}{15} [/tex]

[tex] = \frac{9}{15} [/tex]

[tex] = \frac{3}{5} [/tex]

therefore, the correct answer is option A.

Step-by-step explanation:

The Pythagorean theorem is sqrt(a^2 + b^ 2) = c, so:

sqrt(22^2 + 8^2) = c

=========================================================

Explanation:

Problem 1

Focus on one of the triangles (they're identical copies of each other).

Each triangle is a 30-60-90 triangle.

The hypotenuse is 8 which cuts in half to 4 to be the short leg.

The long leg is [tex]\sqrt{3}[/tex] times that of the short leg, meaning the long leg is [tex]4\sqrt{3}[/tex] inches long.

The area is therefore length*width = [tex]4*4\sqrt{3} = 16\sqrt{3}[/tex] square inches.

------------------------------

Problem 2

For a 30-60-90 triangle, the short leg x doubles to 2x when getting the hypotenuse. Only choice A fits with this description when going from 2 to 4.

------------------------------

Problem 3

The legs of a 45-45-90 triangle are the same length. This narrows our answer choices to B and D. We can conclude the final answer is B since the hypotenuse is exactly [tex]\sqrt{2}[/tex] units longer compared to the leg length.

------------------------------

Problem 4

A 30-60-90 triangle forms.

The 60 degree angle is between the ladder and the horizontal ground. The 30 degree angle is placed up top. Opposite the 30 degree angle is the horizontal side, which is of length of 7 feet mentioned. Doubling this gets to 2*7 = 14 feet and it's the hypotenuse.

Answer: 9 x 5 1/3

Step-by-step explanation: 9 x 5 1/3 = 9 x 16/3 which can be simplified to 3 x 16 = 48.

Answer:

Add f(x) = y.

Step-by-step explanation:

Desmos won't like this equation because it says you will need to define
"some of the variables". Assuming you want f(x) to be equal to a x=y line, you can add another equation where you denote f(x) to be equal to y.

Answer:

2 and 4

Step-by-step explanation:

1% of 72 is 0.72
0.72 * 40

is 28.8

10% of 72 is 7.2

7.2 * 4 is also 28.8

40% of 70 is 28.8

Step-by-step explanation:

14.

G must be congruent to B (the vertexes with the right angle).

and then

GH = GF = CB = AB (they are both isoceles triangles meaning both legs have the same length, and then these legs must be congruent bergen the triangles, so, in fact, all 4 sides must have equal length).

therefore,

5y mm = 25 mm

y = 5

(2x + 5) mm = 25 mm

2x + 5 = 25

2x = 20

x = 10

(3z + 14) mm = 35 mm

3z + 14 = 35

3z = 21

z = 7

Answer:

(5x^2-6)*(2x-7)

Step-by-step explanation:

1.(((10 • (x3)) -  (5•7x2)) -  12x) +  42

2.(((2•5x3) -  (5•7x2)) -  12x) +  42

3. 10x3-35x2-12x+42  is not a perfect cube

4.Factoring:  10x3-35x2-12x+42

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  -12x+42

Group 2:  10x3-35x2

Pull out from each group separately :

Group 1:   (2x-7) • (-6)

Group 2:   (2x-7) • (5x2)

              -------------------

Add up the two groups :

              (2x-7)  •  (5x2-6)

5.  Factoring:  5x2-6

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

=  (5x2 - 6) • (2x - 7)

that should be the answer tell me if i got it wrong and ill try to fix it.

Given that Janelle travels at 65 mph. the number of more hours it will

take her to reach her destination is approximately 5 hours.

Possible part of the question that appear missing are;

The distance Janelle drove in 4 hours = 260 miles

The distance from which she started = 575 miles

Required:

The number of extra hours it will take her to reach her destination

Solution:

The remaining distance = 575 miles - 260 miles = 315 miles

[tex]Speed = \mathbf{ \dfrac{Distance}{Time}}[/tex]

[tex]Janelle's \ average \ speed = \dfrac{260 \, miles }{4 \, hours} = \mathbf{ 65 \, mph}[/tex]

[tex]Time = \dfrac{Distance}{Speed}[/tex]

Which gives;

[tex]Time \ to \ reach \ her \ destination = \dfrac{315 \, miles}{65 \, mph} = 4\frac{11}{13} \, hours \approx \mathbf{ 5 \, hours}[/tex]

The time it takes Janelle to reach her destination ≈ 5 hours

Answer: $27 for four large pizzas is cheaper than 32$ for five large pizzas

Step-by-step explanation:

Answer:

$32 for 5 pizzas

Step-by-step explanation:

Assuming you're trying to determine which option is the better deal, the first step would be to determine the price per pizza.

Option 1: $27 for 4 pizzas

$27 / 4 pizzas = $6.75 per pizza

Option 2: $32 for 5 pizzas

$32 / 5 pizzas = $6.40 per pizza

Option 2 is the better deal because each pizza costs less.

Answer:

Linear Equation: y=-44000x+88922000

Year 2009: $526000

By year 2021, they have no more fund

Step-by-step explanation:

Slope formula is difference of y/difference of x. 79000-70200/2003-2005=

-88000/2=-44000.

To find the y intercept, x=0.

It should be year 0. 44000x2003=88132000+790000=88922000

Now put it into y=mx+b

y=-44000x+88922000

Plug in 2009.

It should equal 526000.

Step-by-step explanation:

[tex]x + 3x + 90 \degree = 360 \degree \\ \\ \implies \: 4x = 360 \degree - 90 \degree \\ \\ \implies \: 4x = 270 \degree\\ \\ \implies \: x = \frac{270 \degree}{4} \\ \\ \implies \: x = 67.5 \degree[/tex]
