answer:

32 dimes and 14 quarters

step by step:

32 x 10 = 320

14 x 25 = 350

320 + 350 = 670

670¢ =  6.70$

Answer:

E = 41

Step-by-step explanation:

E = (-52) + 13 + 49 + (-15) + (-36) + 82

Take the -ve terms to one side and +ve terms to the other.

E = (13 + 49 + 82) - 15 - 36 - 52

E = 144 - 103

E = 41

so we know m<3=70

m<2=90

m<2+m<1=m<4

try 50?

let me know if it is wrong

h = 2 + 32t - 16t^2 is the function given to model the balls flight and we want to know what time the ball is at 15 feet in the air, which is at 2 points in time since the ball takes a parabolic trajectory.

15 = 2 + 32t - 16t^2

0 = -16t^2 + 32t -13

since the equation isn't factorable we will use the quadratic formula.

(-b +- sqrt(b^2 - 4ac))/2a

=

we end up with t = (4+-sqrt(3))/4 which is t = 1.43 seconds and t = 0.57 seconds when approximated.

Answer:

c  the factor of the inequality is correct - took this test already

Step-by-step explanation:

To solve this issue, first we have to match the denominators, for this we have to take the LCM from the denominators 5.6, Then just solve the fraction normally, See:

[tex]\sf \dfrac{4x}{5}+\dfrac{5x}{6}\to LMC~(5,6)=30\\\\\\\sf =\dfrac{24x}{30}+\dfrac{25x}{30}\\\\\\\sf =\dfrac{24x+25x}{30}\\\\\\\boxed{\sf \frac{49x}{30}}[/tex]

Answer:

15x-18

Step-by-step explanation:

use pemdas

do parenthesis first

6(4x-3)-9x

24x -18 -9x

15x-18

The simplified expression after applying the distributive rule for the expression 6(4x - 3) - 9x becomes 15x - 18

The given expression is:

6(4x-3)-9x

Expanding the expression using the distributive rule

24x - 18 - 9x

Collect like terms

24x - 9x - 18 (since 24x and 9x are similar)

The resulting expression becomes:

15x - 18

The simplified expression after applying the distributive rule for the expression 6(4x - 3) - 9x becomes 15x - 18

Answer:

2.5

Step-by-step explanation:

"Four different positive integers have a mean (average) of 100"

The total of the 4 numbers is then 4* 100 = 400

"the positive difference between the smallest and largest of these integers is as large as possible"

to get the greatest difference the first 3 numbers must be

1, 2 and 3 which totals 6

the 4th number is then 400 - 6 = 394

the four numbers are 1, 2, 3 and 394

The greatest difference is between 1 and 394

"the average of the other two integers"

(2 + 3)/2 = 2.5

The average of the other two integers is 1.5.

An integer is an whole number. An example of an integer is 20.

If the mean of the four integers is 100. It means that the sum of the integers must be 400. If the integers are 0,1,2, 397. The largest number is 397 and the smallest number is 0. The average of the other two integers is (1 + 2 ) / 2 = 1.5

Answer:

x = 7

Step-by-step explanation:

I'm assuming ΔJKL and ΔMNP are similar as you wouldn't be able to solve it otherwise. ∠J≅∠M and ∠K≅∠N, so I assume its just a poorly formed question.

With that assumption made, if 2 triangles are similar, the scale factor on all sides are equal. That means this:

[tex]\frac{JK}{MN} =\frac{JL}{MP}[/tex]

The scale factor is just the new length divided by the old length, and that equation shows the scale factor on both of those side lengths are the same. With 3 of the 4 side lengths, you can plug those values in and solve for the last unknown.

[tex]\frac{25}{30} =\frac{20}{4x-4}[/tex]

I use cross multiplication here:

[tex]25(4x-4)=20(30)\\100x-100=600\\100x=700\\x=7[/tex]

y = 5

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through all points with a y- coordinate of 5 , then

y = 5 ← equation of line

Answer:

(4 + d) × 2

Step-by-step explanation:

Step-by-step explanation:

sum of 2 angles on a straight line = 180°

therefore,

y + 120 = 180

y = 180 - 120 = 60

y = 60°

now apply angle sum property of triangle

now,

50 + x + y = 180

50 + x + 60 = 180

110 + x = 180

x = 180 - 110

x = 70

therefore, x = 70 & y = 60

Answer:

x=21

<1=120

Step-by-step explanation:

So to find x set up an equation like this:

(5x+15)+(3x-3)=180

since the bottom and top lines are congruent they are 'interior angles on the same side of a transversal' which are always supplementary, so that's where 180 comes from.

calculate the equation and you'll get x=21 :D

next to find 1 just put 21 in place of x: 3(21)-3=60

since it's supplementary to angle 1 you take 180-60=120

angle <1=120!
