Answer:

5

Step-by-step explanation:

The number of cubes that should be on each side of the frame should be considered as the 5.

Since Sally used 8 cubes to make this square frame that has 3 cubes on each side.

So here the no of the cube be like

= 8  - 3

= 5

hence, The number of cubes that should be on each side of the frame should be considered as the 5.

Answer: 8

Step-by-step explanation:

Given

lottery win is inversely proportional to the number of tickets matching the correct number.

Suppose lottery amount is given by A and no. of tickets by n then

[tex]\Rightarrow A\propto \frac{1}{n}\\\Rightarrow A\cdot n=\text{constant}[/tex]

Initially A=£1400, n=20

then A=£3500, n=?

Product in both the case is same

[tex]\therefore \quad 1400\times 20=3500\timesn\\\Rightarrow n=8[/tex]

There are 8 tickets that matched the correct numbers

Answer:

x = 19.06 feet

Step-by-step explanation:

Given that,

The length of a tree, h = 16 feet

It casts a shadow which forms an angle of 40° with the ground.

We need to find the length of the shadow. We can find it using trigonometry such that x be the length of the shadow. So,

[tex]\tan\theta=\dfrac{h}{x}\\\\x=\dfrac{h}{\tan\theta}\\\\x=\dfrac{16}{\tan(40)}\\\\x=19.06\ \text{feet}[/tex]

So, the length of the shadow is 19.06 feet.

Answer:

The slope is 1/3

Step-by-step explanation:

Equation for slope is rise over run or y2-y1/x2-x1

-5,1 -2,2 these are the 2 points, so it could be 2-1/-2--5 which is equal to 1/3.

Answer:

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Step-by-step explanation:

It's possible because they cut cakes into different number of slices.

You know that Luke, Kira and Ali each served [tex]\frac{2}{3}[/tex] of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.

Being x the whole slices of cake, and if Luke served [tex]\frac{2}{3}[/tex] of his cake, which are 4 slices, the whole slices of cake of Luke is:

[tex]\frac{2}{3}*x=4 slices[/tex]

Solving:

x= 4 ÷[tex]\frac{2}{3}[/tex]

x= 6

Then, whole slices of Luke's cake is 6.

Performing the same approach for Kira you get:

[tex]\frac{2}{3}*x=6 slices[/tex]

x= 6 ÷[tex]\frac{2}{3}[/tex]

x= 9

Then, whole slices of Kira's cake is 9.

Finally, performing the same approach for Ali you get:

[tex]\frac{2}{3}*x=8 slices[/tex]

x= 8 ÷[tex]\frac{2}{3}[/tex]

x= 12

Then, whole slices of Ali's cake is 12.

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Answer:

B

Step-by-step explanation:

Answer:

y =9

Step-by-step explanation:

you know the distance is 10 and some of the x,y points. so start filling what you know into the distance formula

10= √((9-1)^2 + (y-3)^2 )

square both sides to get ride of the square root

100 = 64 + (y-3)^2

36 = (y-3)^2

6 = y-3

y = 9

double check by using 9 for Y and you'll see it works.

Answer:

6

Step-by-step explanation:

since it's a right triangle you can use the Pythagorean Theorem

2.7² + b² = 6.5²

7.29 + b² = 42.25

b² = 34.96

b = [tex]\sqrt{34.96}[/tex] which equals 6 when rounded to the nearest tenth

Answer:

Number of non defective bulbs-

400-24

376

Our fraction would be-

376/400

To make it into percentage we need to always multiply it by 100

376/400 x 100

=94%

Thus 94% of the bulbs are non defective

9514 1404 393

Answer:

26

Step-by-step explanation:

100 +(24^2) = 676

square root of 676 = 26

Answer:

either 26 m or 21.8174 m

Step-by-step explanation:

If 24 is the hypotenuse, then 24^2-10^2=x^2

x^2=576-100=476

x=21.8174 m

if x=hypotenuse, then 24^2+10^2=x^2

x^2=576+100=676

x=26 m

Answer:

11.14

Step-by-step explanation:

Mean = sum of numbers / total numbers

the mean of the 7 numbers = sum of the numbers / 7

sum of numbers for the 3 numbers = 10 x 3 = 30

Sum of numbers for the other 4 numbers = 12 x 4 = 48

Sum of the 7 numbers = 48 + 30 = 78

Mean of the 7 numbers = 78 / 7 =  11.14

Answer:

x = 17

Step-by-step explanation:

Assuming you require to find x

4x - 3 and 115 are same- side interior angles and supplementary, sum to 180°

4x - 3 + 115 = 180

4x + 112 = 180 ( subtract 112 from both sides )

4x = 68 ( divide both sides by 4 )

x = 17
