Answer:

Dave had most fun for 1.5 minutes.

explanation:

Let the "fun time" be f

total time * portion of time fun  = fun time

[tex]\sf t * p = f[/tex]

[tex]\sf 6 \ * \frac{1}{4} = f[/tex]

[tex]\sf \frac{6}{4} = f[/tex]

[tex]\sf f = 1.5 \ minutes[/tex]

Question was for how many minutes, Dave had fun, so he had fun for 1.5 minutes

Let that half be x

So

[tex]\\ \rm\Rrightarrow x(4)=6min[/tex]

[tex]\\ \rm\Rrightarrow x=6/4[/tex]

[tex]\\ \rm\Rrightarrow x=1.5min[/tex]

Answer:

C

Step-by-step explanation:

supplementary angles sum to 180° , then

3x + 15 + 60 = 180 , that is

3x + 75 = 180 ( subtract 75 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

Answer:

y=10

Step-by-step explanation:

y=10

Answer:

y=10

Step-by-step explanation:

plug-in 2 to x

[tex]y=4(2)+2[/tex]

multiply 4 and 2

[tex]y=8+2[/tex]

add 8 and 2

[tex]y=10[/tex]

Answer:

98 cm

Step-by-step explanation:

sum the parts of the ratio , 2 + 4 + 7 = 13 parts

divide perimeter by 13 to find the value of one part of the ratio.

182 ÷ 13 = 14 cm ← value of 1 part of the ratio , then

2 parts = 2 × 14 = 28 cm

4 parts = 4 × 14 = 56 cm

7 parts = 7 × 14 = 98 cm

the longest side is 98 cm

Answer:

  5x + 12 = 5x - 7

Step-by-step explanation:

There will be no solution when the coefficients of x are the same on both sides of the equal sign and the constants are different. That is the case for ...

  5x + 12 = 5x - 7

This reduces to ...

  19 = 0 . . . . . no value of x will make this be true: NO SOLUTION

Step-by-step explanation:

Answer:

Well the only answer to this question that I can think of is 360 that's because all of the angles in a circle are equal to 360.

Step-by-step explanation:

Explicación paso a paso:

Dado

an = n + 3

bn = 5n-1

a) an-bn = n + 3- (5n-1)

= n + 3-5n + 1

= n-5n + 3 + 1

= -4n + 4

an-bn = 4-4n

b) an + 3bn = (n + 3) +3 (5n-1)

= n + 3 + 3 (5n) +3 (-1)

= n + 3 + 15n-3

= n + 15n + 3-3

= 16n + 0

= 16n

an + 3bn = 16n

3) Dado a1 = 1, a2 = 1

an = an-1 + an-2

Debemos escribir los primeros ocho términos de la secuencia.

a3 = a3-1 + a3-2

a3 = a2 + a1

a3 = 1 + 1

a3 = 2

a4 = a3 + a2

a4 = 2 + 1

a4 = 3

a5 = a4 + a3

a5 = 3 + 2

a5 = 5

a6 = a5 + a4

a6 = 5 + 3

a6 = 8

a7 = a6-a5

a7 = 8 + 5

a7 = 13

a8 = a7 + a6

a8 = 13 + 8

a8 = 21

Por tanto, los primeros ocho términos de la secuencia son 1, 1, 2, 3, 5, 8, 13 y 21

Step-by-step explanation:

Answer:

B) 0.42

Step-by-step explanation:

population density=number of people/square units

we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π[tex]r^{2}[/tex] so the radius is 40 millimeters so [tex]40^{2}[/tex] =1600 1600*π=5024

2,100/5024=0.417 round it up and it is 0.42

so B) 0.42 is the answer

Answer: 160 miles

Step-by-step explanation: From 10:20 to 12:20 is 2 hours which is 120 minutes and it is 60mph so it is 1 mile per minute. 12:20 to 1:00 is 40 minutes so you add 40 to 120 which makes it 160. So the answer is 160 miles

I might be wrong but i rlly hope this helps u in some way :)

Answer:

[tex]3c > -26[/tex]

Step-by-step explanation:

"The product of c and 3" means to multiply c with 3: [tex]c * 3[/tex] or [tex]3c[/tex]

"is greater than": [tex]>[/tex]

"-26": -26

Put the terms together:

"The product of c and 3 is greater than 3": [tex]3c > -26[/tex]

Rewriting the whole as an Equivalent Fraction

4.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  (x-8)  as the denominator :

         -2     -2 • (x - 8)

   -2 =  ——  =  ————————————

         1        (x - 8)  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3x2 + -2 • (x-8)     3x2 - 2x + 16

————————————————  =  —————————————

   1 • (x-8)          1 • (x - 8)

Trying to factor by splitting the middle term

4.3     Factoring  3x2 - 2x + 16

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   3 • 16 = 48

Step-2 : Find two factors of  48  whose sum equals the coefficient of the middle term, which is   -2 .

     -48    +    -1    =    -49

     -24    +    -2    =    -26

     -16    +    -3    =    -19

     -12    +    -4    =    -16

     -8    +    -6    =    -14

     -6    +    -8    =    -14

Answer:

Part A: 1

Explain: The solution for a pair of lines is where they intersect.

Part B: (3,4)

Explain: (3,4) is the place where the lines intersect.

Step-by-step explanation:

-3/8 × 1 × -9/10 × -8/3

we know

- × - = +

+ × - = -

therefore, since we have 3 negative factors we get a negative result.

we can ignore the completely neutral multiplication by 1.

-3/8 × -9/10 × -8/3 = -(3×9×8)/(8×10×3) = -9/10

Answer:

169

Step-by-step explanation:

Use a proportion:

72/85=x/200

Solve for x

(72)(200)=85x

x=(72)(200)/85

x=169.41≈ 169

She can make 169 of 200 free throws.

P = 40 + 12 + 28 + 16 + 12 + 28

P = 136 ft.
