Answer: 80 children are in the 3rd grade

Step-by-step explanation:

Call the number of children in the 3rd grade = a

=> 64 = [tex]\frac{4}{5}[/tex] x a

a = 64 : 4/5

a = 80

Answer:

axis of symmtery: x = 3 or h = 3

Step-by-step explanation:

The vertex (h, k) of a parabola is the point wherein the graph intersects the axis of symmetry—the imaginary straight line that bisects a parabola into two symmetrical parts, where x = h.

Regardless of whether the quadratic equation is in standard or vertex form, the x-coordinate (h) of the vertex determines the axis of symmtetry, hence, x = h.

Therefore, given that the vertex of a parabola is at point (3, 5), then it means that the axis of symmetry occurs at x = 3 or h = 3.      

Answer:

The inside angles of a pentagon add up to 540 degrees. The four given angles add up to 433 which means that the interior angle that remains unknown is 107 degrees. That means that the measure of angle a is 73

Answer:

Segment RW congruent to segment XY

Step-by-step explanation:

SAS means side-angle-side.

You are given two congruent angles, so you already have the angle you need for SAS.

By the reflexive property, side XW is congruent to itself, so now you have a side also.

You need another pair of sides, but the two sides must include the angle.

Answer: Segment RW congruent to segment XY

Answer:

the answer is p=10.5

Step-by-step explanation:

5p+3=15

5p=15-3

p=12/5

p=10.5

first lets change this problem into an equation...

0.09*x+0.15*3000=0.12(x+3000)

Step 1: Simplify both sides of the equation.

0.09x+(0.15)(3000)=0.12(x+3000)

0.09x+(0.15)(3000)=(0.12)(x)+(0.12)(3000)

0.09x+450=0.12x+360

Step 2: Subtract 0.12x from both sides.

0.09x+450−0.12x=0.12x+360−0.12x

−0.03x+450=360

Step 3: Subtract 450 from both sides.

−0.03x+450−450=360−450

−0.03x=−90

Step 4: Divide both sides by -0.03.

-0.03x/-0.03=-90/0.03

Answer:

4/3 or 1  1/3

Step-by-step explanation:

Answer:

4/3 or 1and1/3

Step-by-step explanation:

To find the slope, all we need to do is plug in both coordinates into the slope formula and the result will be the slope.

the slope formula is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

to make it easier, we can label each x and y as x2, x1, y2, and y1 (it really doesn't matter which y or x value is the one as long as they are from the same pair like (4,3) can be x1 and y1 but can't be x2 and y1)

(4,3) (x1,y1)            (1,-1)  (x2,y2)

so just plug it into the formula and solve:

[tex]m=\frac{-1-3}{1-4} =\frac{-4}{-3} =\frac{4}{3} or 1\frac{1}{3}[/tex]

Sydney has$42 dollars in her piggy bank Step-by-step explanation: if she put one dollar in her bank for 3 weeks you do 7x3 and get 21 you double that and then you 21x2 and get 41 add that one dollar Tell me if im wrong

Sydney would have $7 in her account in 3 weeks.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following problem -

Sydney put $1 in her Piggy bank. For the next three weeks Sydney doubled the amount she put in her bank.

Assume that she saves $y in [x] weeks. We can model the linear function of her saving as -

y = 1 + 2x

or we can write -

y = 2x + 1

For x = 3, we will have -

y = 7

Therefore, Sydney would have $7 in her account in 3 weeks.

#SPJ2

Answer:

78° +78°+3x-12= 180 {being isosceles triangle and sum of 3angles of a triangle is 180°}

156+ 3x-12=180

144+3x=180

3x=180-144.

3x=36

[tex]x = \frac{36}{3} [/tex]

x=12

[] 10x + 4

(5x) + (2x + 5) + (3x - 1)

5x + 2x + 3x + 5 - 1

10x + 4

[] 4x + 4

Bottom: (1/2) * (3x -1) = 1/2x - 1/2

Left side: (1/2) * (5x) = 5/2x

Right side: (1/2) * (2x+5) = x + 5/2

\/

Add them together:

(x + 5/2) + (5/2x) + (1/2x - 1/2)

x + 5/2x + 1/2x + 5/2 - 1/2

4x + 4

[] The Triangle Midsegment Theorem (midsegment = 1/2 times triangle base) and then calculated by adding the three midsegments together.

     Hope this helps and is correct, have a nice day! :D

check attached file for a diagram I made

     Note: I realized after it was made I did the midsegment wrong so ignore that part! It should be a triangle with the three points in the middle of the sides.
