Step-by-step explanation:

Because if you have the value 4 does not go into 7, so if you have a number line< You 7 from 4 below 0, and YOU will GET -3

Talia bought a home for her pet turtle the rectangular tank is 3 feet long. 1 foot wide and 2 feet high. What is the volume?

Serggg [28]

Answer:

Volume of rectangular tank = 6 cubic feet

Step-by-step explanation:

Length of the rectangular tank = 3 feet

Width of the tank = 1 feet

And height of the rectangular tank = 2 feet

Since, tank is in the shape of a cuboid,

Volume of a cuboid = Length × Width × height

= 3 × 1 × 2

= 6 cubic feet

Therefore, volume of the rectangular tank will be 6 cubic feet.

Pamela ran 7/10 mile on Tuesday and 3/8 mile on Thursday. How much fatter did she run on Tuesday ?

Len [333]

Answer:

$Difference = \frac{13}{40}$

Step-by-step explanation:

Given

$Thursday = \frac{3}{8}\ mile$

$Tuesday = \frac{7}{10}\ mile$

Required

How much farther is she on Tuesday

To do this, we simply calculate the difference between distance covered on both days.

$Difference = Tuesday-Thursday$

$Difference = \frac{7}{10} - \frac{3}{8}$

Take LCM

$Difference = \frac{28- 15}{40}$

$Difference = \frac{13}{40}$

<em>Hence, she ran 13/40 mile farther on Tuesday</em>

The relationship between women’s whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length

ad-work [718]

Answer:

The explicit formula for Arithmetic Sequence is $a_n=7.02+0.33n$

Step-by-step explanation:

Given: Foot length & shoe size in AP.

$a_n$ is foot length and n is shoe size.i.e., $a_{12}=11\:and\:a_7=9.33$

To find: Formula for Arithmetic sequence .i.e., $a_n$

From question,

$a_{12}-a_7=11-9.33=1.67$

Also, we know that

$a_{12}=a_7+5d\\5d=a_{12}-a_7\\5d=1.67\\d=\frac{1.67}{5}\\\\d=0.33$

Now, consider

$a_7=a_1+6d\\a_7=a+6d\\a=a_7-6d\\a=9.33-6\times0.33\\a=9.33-1.98\\a=7.35$

Thus using formula of $a_n$ we get,

$a_n=a+(n-1)d\\a_n=7.35+(n-1)\times0.33\\a_n=7.35+0.33n-0.33\\a_n=7.02+0.33n$

Therefore, The explicit formula for Arithmetic Sequence is $a_n=7.02+0.33n$

The figure is made up of a cylinder and a cone. What is the volume of the composite figure? Use 3.14 for Pi. Round to the neares

Delvig [45]

Answer:

The volume of figure is 310.86 cm³

Step-by-step explanation:

First, you have to calculate the volume of cone and cylinder seperately by applying the formulas :

Cone,

$v = \frac{1}{3} \times \pi \times {r}^{2} \times h$

$let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 9$

$v = \frac{1}{3} \times 3.14 \times {3}^{2} \times 9$

$v = 84.78 \: {cm}^{3}$

Cylinder,

$v = \pi \times {r}^{2} \times h$

$let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 8$

$v = 3.14 \times {3}^{2} \times 8$

$v = 226.08 \: {cm}^{3}$

Next, you have to add up both volumes as the figure are made from cone and cylinder :

$v = 84.78 + 226.08$

$v = 310.86 \: {cm}^{3}$

Find the slope of the line that passes through the points (3, -6) and (6, 12).

Svetradugi [14.3K]

The slope of a line is simply a ratio of the change in y-value to the change in x-value
Change in y = y₂ - y₁
= 12 - (-6) = 18
Change in x = x₂ - x₁
= 6 - 3 = 3
Ratio of change in y to change in x = 18/3 = 6
The slope is 6
