Answer:

1) 128/225

2)1  7/60

Step-by-step explanation:

1)

(3/5+1/9)x4/5

32/45x4/5

128/225

2)

2/3+1/5+1/4

13/15+1/4

1  7/60

1. Answer:

128/225

Step-by-step explanation:

Find the lest common denominator for 3/5 + 1/9 which is 45. 3/5 times 9, 1/9 times 5. So, then you have 27/45 + 5/45 = 32/45. So, then you do 32/45 times 4/5. 45 times 5 is 225. 32 times 4 is 128.

2. Answer:

1 7/60

Step-by-step explanation:

LCD for 3,5,4=60. 3 times 20 = 60. 5 times 12 equals 60. 4 times 15 equals 60.

So, then do 2 times 20 equals 40. 1 times 12 equals 12. 1 times 15 equals 15.

[tex]\frac{40}{60}+\frac{12}{60}+\frac{15}{60}[/tex] = [tex]\frac{67}{60} = 1 \frac{7}{60}[/tex]

Hope this helps!

Answer: 2125 cm^2

Step-by-step explanation:

We will need to find the surface area of the pyramid:

SA = (1/2)Pl(slanted height) + b

SA = (1/2)(25*4)(30) + 25^2

SA = 1500 + 25^2

SA = 2125 cm^2

Answer:

The line with blue dots is steeper.

Step-by-step explanation:

The higher the slope means a steeper line.

If we get 2 points from the line with blue dots (1,3) and (2,6) and plug it into the formula to find the slope, (y1-y2) / (x1-x2), the slope is 3.

To find the slope of the line with black dots, we do the same thing just with different coordinate points, (1,2) and (2,4). The slope is 2, which is less than the slope of the other line.

Therefore the line with blue dots is steeper.

Answer:

First thing i noticed was that the height has a big difference in both graphs. Also blue is more spaced out and has more steepness in it Compared to the black graph. Blues steepness is greater by 4 units.

Step-by-step explanation:

-12s squared +11st -2tsquared

-3s *4s = 12s squared

-3s*-t= 3st

2t*4s=8st

2t*-t=2t squared

Answer:

Solution given

side 1:1 units

side 2=4 units

height =3 units

we have

Area of trapezoid =½*height(side1+side2)

=½*3(1+4)=15/2

areas of the trapezoid is 15/2 or 7.5 square units.

Area

Answer:

1 / y^22

Step-by-step explanation:

We multiply bracket powers and add powers if no brackets when multiplying same numbers on same line (denominator with denominator and numerator with numerator, we could cross multiply with (y^7)^6 / (y^7)^6 but workings below show when we simplify then subtract powers last step to reduce the fraction with no action of cross multiply.

(y^4 )^5 = y^20

(y^7)^6 = y^42

= y^20/ y^42

= 1 / y^22

Answer:

A. The number of days Harrison has read since he started the project.

Answer:

Base = 8x8=64

face 1 = 4x5=20

All faces = 20x4=80

80+64=144m squared

Step-by-step explanation:

70-26= 44°

Might be wrong but hope it helped!

Answer:

Hello! answer: p = 44

Step-by-step explanation:

These are vertical angles!

Meaning that each will equal the same

Since we are given its vertical angle we know that it will have to add up to 70 on the other side as well so...

70 - 26 = 44 therefore p = 44 hope that helps!

Answer:

A

Step-by-step explanation:

Multiply 5 with the expression in the bracket you will get 60y-90-20x

Answer:

w x l is area so 6x7 is 42 a=42

add all of the sides up b=144

Answer:

1.) n ≥ 22/3

2.) t > 44

3.) You can buy 5 hot dogs

Step-by-step explanation:

Question 3 explanation:

You can buy 5 hot dogs at the baseball game because each hot dog is $2. If you have $10 then 5 x 2 = 10

Answer:

both include shooting accuracy

both can be done outdoors

both have to be thrown into some type of goal to score points

both require practice to be good

both involve throwing of some sort

Step-by-step explanation:

Answer: x+x=2x

Step-by-step explanation:

Well, it says there are half of the objects in two baskets of the third one.

So x (first box) + x (second box) = 2x (third box)

(also mayumi needs to learn to save boxes too)

Happy to help :)

Answer:

Step-by-step explanation:

(4-2)^3-3*4

=2^3-12

=8-12

=-4

Answer:

the answer should be -4

Step-by-step explanation:

simplify 4-2 into 2

so 2³-3×4

simplify 2³ to 8

so 8-3×4

simplify 3×4 into 12

so 8-12

which then leads to be -4

this question is not about addition and inequality, i've done elementary work that is as easy as this

Answer:

I belive Joe mowed 51 lawns and Marty mowed 23.

Step-by-step explanation:

Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Joe earns a base amount of $15 and $8 per lawn.

Marty earns a base amount of $45 and $6 per lawn.

Let's suppose they both mow x number of lawns.

Then Joe's total income is given by:

$(15+8x)

And Marty's total income is given by:

$(45+6x)

As they earned the same amount of money, mathematically:

(15+8x) = (45+6x)

15 + 8x - 6x = 45 +6x - 6x   (subtract by 6x on both sides)

15 + 2x -15 = 45 -15              (subtract by 15 on both sides)

2x = 30

x = 15    (divide by 2 on both sides)

If we put x = 15 in Joe's total income expression, we get:

15+8×15 ⇒135

If we put x = 15 in Marty's total income expression, we get:

45+6×15 ⇒135

Thus, Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.
