Answer:

62.5

Step-by-step explanation:

From the question, we ware told that triangle ABC is similar to XYZ

Hence Aabc/Axyz = AB/XY

Substitute the given values

25/16 = AB/40

Cross multiply

16AB = 40 * 25

16AB = 1000

AB = 62.5

Hence the length of AB is 62.5

Answer:

A

Step-by-step explanation:

y = - 7 is a horizontal line parallel to the x- axis.

A line perpendicular to it must therefore be a vertical line parallel to the y- axis with equation

x = c

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

The line passes through (- 3, - 8) with x- coordinate - 3, then

x = - 3 ← equation of perpendicular line

Since he USES 4/9th of the dough, what is left is 1-4/9=9/9-4/9=5/9 In math, the word 'of' can translate to 'multiplied by' therefore 5/9 OF the 5pounds of douch left can translate to: 5/9*5=25/9 pounds of dough left (about 2.7 pounds)

Answer:

64

Step-by-step explanation:

Answer:

64

Step-by-step explanation:

I've never explained multiplication but here we go:

Multiplication is literally repeated addition

So 16*4 would just be 16+16+16+16 which we can do the addition out and get 64

We can also do 4 sixteen times and do 4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4

If we add that up, we'll get 64

We can also do distributive property, so we do 4^15 which is 60 and then we do 4*1 which equals 4, then we do 60+4 to get 64. The equation will look like this:

4(15+1)

The percentage decrease of the apples will be 17%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

From 90 apples to 75 apples, the percentage decrease will be:

= (90 - 75) / 90 × 100

= 15 / 90 × 100

= 1/6 × 100

= 17%

Answer:

(-2,4) , (0,5) , (2,6) , (4,7)

Step-by-step explanation:

you just substitute every value of x in the equation and you get y

The remaining values of the table are 4,  5, 6, 7.

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

[tex]Y=\frac{X}{2} +5[/tex]

And,

The table is given,

X | -4, -2, 0, 2, 4

Y |  3,   ?,  ?, ?, ?

Now,

To complete the table,

Put the given values of X in the given expression,

Now,

For, X = -2,

[tex]Y=\frac{X}{2} +5=\frac{-2}{2} +5=-1+5[/tex]

Y = 4,

Now,

For, X = -0,

[tex]Y=\frac{X}{2} +5=\frac{0}{2} +5=0+5[/tex]

Y = 5,

Now,

For, X = 2,

[tex]Y=\frac{X}{2} +5=\frac{2}{2} +5=1+5[/tex]

Y = 6,

Now,

For, X = 4,

[tex]Y=\frac{X}{2} +5=\frac{4}{2} +5=2+5[/tex]

Y = 7,

So, the complete table is ,

X | -4, -2, 0, 2, 4

Y |  3,  4,  5, 6, 7

Hence, we can say that the remaining values of the table are 4,  5, 6, 7.

Answer:

Rs240 000

Step-by-step explanation:

Let the length and breadth of the rectangular field be represented by l and b respectively.

Thus,

l = 3b ............. 1

Perimeter of a rectangle = 2(l + b)

The perimeter of the given rectangle = 800 m, so that;

800 = 2(l + b)

l + b = [tex]\frac{800}{2}[/tex]

       = 400

l + b = 400 ............... 2

But, l = 3b. So that,

3b + b = 400

4b = 400

b = [tex]\frac{400}{4}[/tex]

   = 100

b = 100 m

l = 3b

 = 3 x 100

l = 300

The length of the rectangular field is 300 m, while its breadth is 100 m.

Area of the rectangular field = l x b

                        = 300 x 100

                        = 30 000

Area of the rectangular field is 30 000 [tex]m^{2}[/tex].

Cost of digging the ground at the rate of Rs8 per [tex]m^{2}[/tex] = Rs8 x 30 000

                                            = Rs240 000

Answer:

XZ = 36 cm, BC = 12 cm

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{XZ}{AC}[/tex] = [tex]\frac{XY}{AB}[/tex] , substitute values

[tex]\frac{XZ}{9}[/tex] = [tex]\frac{16}{4}[/tex] = 4 ( multiply both sides by 9 )

XZ = 36 cm

and

[tex]\frac{BC}{YZ}[/tex] = [tex]\frac{AB}{XY}[/tex]

[tex]\frac{BC}{48}[/tex] = [tex]\frac{4}{16}[/tex] ( cross- multiply )

16BC = 192 ( divide both sides by 16 )

BC = 12 cm

Answer:

1 a = 70%

b 6.5 times

c  green = 16%

2.  ?????  Very poorly worded question

2. a 54%

b. 46%

c. 70%

d.  27%

Step-by-step explanation:

1. Students in a class were asked to tell their favorite color.

a. What percent said red, blue, or yellow? __% said red, blue, or yellow.  

red is .26

blue is .40

yellow is .04

---------------------

               .70   = 70 %

b. How many times more students said red than yellow?

red  .26

yellow is .04

.26/.04 =  6.5 times

c. What percent of students said green? __% said green.

The circle must total 100 %

Red + blue + yellow + purple + green = 100

26+     40 +     4           + 14     +  green = 100

84 + green = 100

Subtract 84 from each side

84-84 + green = 100-84

green = 16

2. Which two methods could be used to find the percent of students who said green?

We can either convert the percents to decimals or the decimals to percents

The total percents must equal 100%

The total decimal must equal 1

a. Find the sum of the percents given in the circle graph.

If they only want the ones written on the graph as percents

(14+40) = 54%

b. Find the sum of the percent forms of the numbers given in the circle graph. Subtract the result from 100%.

100 - 54% = 46%

c. Find the sum of the decimal forms of the numbers given in the circle graph. Subtract that sum from 1. Change the result to a percent.

.26+.04 = .3

1-.3 = .7

70%

d. Find the sum of half of the percents given in the circle graph. Subtract that total from 50%.

1/2 (46%) = 23%

50 -23 = 27%

I'll try to explain it as best as I can.
