Stella models a product with algebra tiles. Write a number sentence that best describes her model. Fill in the blanks.

Answer:

285

Step-by-step explanation:

For the top section, we can portion out 20 x 8 = 160.

Next, directly in the middle is a 5 x 5 square = 25.

Finally, we have a right triangle with dimensions 10 x 20 so the area would be 10 x 20 / 2 = 100.

160 + 25 + 100 = 285.

Answer:

take all the numbers and multiply...

Step-by-step explanation:

Step-by-step explanation:

Let the athletes be 3x and 2x.

Now, By the question we get,

(3x-12)/(2x+12) = 5/4

or, 12x-48= 10x+60

or, 2x = 108

so, x = 54

now

3x= 3×54= 162

2x = 2×54=108

The number of athletes were 162 in first team and 108 in second team originally.

x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )

y ----------------------------------------second------------------( y ∈ Nˣ )

The ratio of athletes in the two teams is 3:2

⇒      [tex]\frac{x}{y} =\frac{3}{2}[/tex]              (1)

After 12 athletes move from first team to second, the ratio is 5:4

⇒      [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex]         (2)

(1),(2)  ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]

So: The first team originally has 162 numbers and the second team originally has 108 numbers

ok done. Thank to me :>

2312 FPM for 2.6 minutes

2312 x 2.6 = 6011.2

28 FPM for 2 minutes

28 x 2 = 56

6011.2 descend

55 ascend

0-6011.2 = -6011.2

ans + 56 = -5955.2

:)

Answer:

Descends: 2,312 x 2.6 = - 6,011 (when rounding otherwise known as - 6,011.2, this number is negative because he is descending)

Ascends: 28 x 2 = 56

- 6,011 + 56 = -5,955 (in 4.6 minutes)

Step-by-step explanation: I took the test

Answer: what I think the answer is 480 letter D

Step-by-step explanation:

Answer:

A. 139,799,000 square miles

B. 57,101,000 square miles

Step-by-step explanation:

71% ÷ 100 = 0.71

0.71 x 196,900,000 = 139,799,000

100 - 71 = 29

29 ÷ 100 = 0.29

0.29 x 196,900,000 = 57,101,000

another way; knowledge of A

196,900,000 - 139,799,000

= 57,101,000

8th:   38

9th:   43

10th:  48

11th:   53

Answer:

8.06

Step-by-step explanation:

Decimals go in the order 10ths hundredths thousandths ten thousandths and so on. In rounding any decimal, one number gets added to the left if the number is 5 or over and the number is discarded if it is lower than 5.

for example if the number was 1.2345      5 would make 4 5 1.235 then 5woould make 3 4 1.24 but if you want to round to a smaller number the other numbers would not go up the numbers would just be discarded.

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above.  Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7).  Then,  y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).  

Another way to get this result would be to find m in the usual way:

          rise           14

m = ------------- = --------- = -14/17 (same as before).

           run           -17

I know this is most likely a joke but I'll answer anyways :)

"Mathematically" you might have poor education whether it's bad teachers, bad school, or maybe you're just not working hard enough. Maybe you are educated and you're just comparing yourself against smarter people which might make you seem not very educated. Or maybe you're secretly a super genius prodigy and you're just too lazy too show it. Who knows...

Answer:

-3.57

Step-by-step explanation:

Answer:

1.5 m

Step-by-step explanation:

Area = length * width

or we can say

Area = side1*side2

since they are the same we can say

Area = side * side

which also means area = side^2

so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting

so

sqrt(Area) = side

so

side = sqrt(2.25)

= 1.5 m

Step-by-step explanation:

In the diagram, line p is parallel to line q. Parallel lines p and q are cut by transversals r and s. At the intersection of lines p, r, and s, clockwise from top left, the angles are C, 93 degrees, A, A, C, B. At the intersection of lines q and s, the angles are B, 60 degrees, A, C. At the intersection of r and q, the angles are 27 degree angles, C, A, B.

Answer: the first answer for dropdown menu1. is (an alternate interior angle)

the second dropdown menu answer is ( C. )

the third dropdown menu answer is ( 180 )

Step-by-step explanation:

mAngleA = 27° because it is  

✔ an alternate interior angle

to the 27° angle.

The measure of Angle

✔ C

can be found because it is a vertical angle to the 93° angle.

The sum of the measures of angles A, B, and C is  

✔ 180

the whole thing is 47 so you take away 17 because thats the starting point of c to d so then you have ur answer hope this helped :))))))))))

Answer:

It is D

Step-by-step explanation:

You just do this

[tex]47 - 17 = 30[/tex]

Perimeter of her rectangular back yard is: 200 ft

⇒ 2(30 + 60 + x) = 200

⇒ 30 + 60 + x = 200/2 = 100

⇒ 90 + x = 100

⇒ x = 100 - 90 = 10
