Complete Question

Phrases can be used to represent the inequality 6.5x+ 1.5 ≤ 21? Select two options. The product of 6.5 and the sum of a number and 1.5 is no more than 21. The sum of 1.5 and the product of 6.5 and a number is no greater than 21. O The product of 6.5 and a number, when increased by 1.5, is below 21. The sum of 1.5 and the product of 6.5 and a number is at least 21.

Answer:

The product of 6.5 and a number, when increased by 1.5, is at most 21.

The product of 6.5 and a number, when increased by 1.5, is below 21.

Step-by-step explanation:

We are given the inequality is: 6.5x+ 1.5 ≤ 21

The sign ≤ is known as Less than or equal to.

≤ can also be said to be = at most

Therefore, the Phrases that represents the inequality

6.5x+ 1.5 ≤ 21 is:

* The product of 6.5 and a number, when increased by 1.5, is at most 21.

* The product of 6.5 and a number, when increased by 1.5, is below 21.

Answer:

10 i think

Step-by-step explanation:

Answer: 10 pounds per year

The given unit rate is 30 pounds every 3 years.

Now, we will divide 30 pounds by 3 years.

30 pounds ÷ 3 years = 10 pounds per year

The answer is 10 pounds per year.

Answer:

17 animals

Step-by-step explanation:

Rachel has a collection of 40 stuffed animals

3/8 are bears

= 3/8 ×40

= 120/8

= 15

1/5 are dogs

= 1/5×40

= 40/5

= 8

15+8

= 23

Therefore the number of animal she have left can be calculated as follows

= 40-23

= 17

Hence there are 17 animals left

Answer:

30.8

Step-by-step explanation:

1. Write the ratio for the smaller triangle as 14/10 and the ratio for the larger triangle as x/22.

2. Set the ratios equal to each other.

14/10 = x/22

3. Cross multiply and solve for x.

14 x 22 = 308

10 x x = 10x

4. Divide by 10

x = 30.8

Answer:

10 pounds will cost $17.50

Step-by-step explanation:

(5.25 / 3) * 10 = x

1.75 * 10 = x

17.50 = x

Answer:

10 pounds of apples will cost $17.50.

Step-by-step explanation:

First, we need to find the unit rate.

$5.25/3 = $1.75

Now we need to multiply $1.75 by 10 pounds.

$1.75 × 10 = $17.50

The table with the missing number

1       5

2     10

5      25

10    50

Step-by-step explanation:

The form of the equivalent ratios is [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] , where a, b, c, and d are integers

From the given table, we will use the first row in all cases (a = 1 and c = 5)

∵ a = 1 and b = 2

∵ c = 5

→ By using the form of the equivalent ratios above

∴ [tex]\frac{1}{2}[/tex] = [tex]\frac{5}{d}[/tex]

→ By using the cross multiplication

∵ 1 × d = 2 × 5

∴ d = 10

∴ The first missing is 10

∵ a = 1

∵ c = 5 and d = 25

→ By using the form of the equivalent ratios above

∴ [tex]\frac{1}{b}[/tex] = [tex]\frac{5}{25}[/tex]

→ By using the cross multiplication

∵ 5 × b = 1 × 25

∴ 5b = 25

→ Divide both sides by 5

∴ b = 5

∴ The second missing is 5

∵ a = 1 and b = 10

∵ c = 5

→ By using the form of the equivalent ratios above

∴ [tex]\frac{1}{10}[/tex] = [tex]\frac{5}{d}[/tex]

→ By using the cross multiplication

∵ 1 × d = 10 × 5

∴ d = 50

∴ The third missing is 50

∴ The equivalent ratios are [tex]\frac{1}{5}[/tex] = [tex]\frac{2}{10}[/tex] = [tex]\frac{5}{25}[/tex] = [tex]\frac{10}{50}[/tex]

Step-by-step explanation:

Answer:

∠ JHF = 69°

Step-by-step explanation:

Since HJ is a midline then it is parallel to EG , thus

∠ JHF and ∠ GEH are corresponding and congruent, then

7x + 62 = 79 - 10x ( add 10x to both sides )

17x + 62 = 79 ( subtract 62 from both sides )

17x = 17 ( divide both sides by 17 )

x = 1

Thus

∠ JHF = 7x + 62 = 7(1) + 62 = 7 + 62 = 69°

Answer:

7x + 62 = 180

7x= 180 - 62

x = 118 / 7

x = 16

7 × x = 7 × 16

112 + 62 = 174

Step-by-step explanation:

Area of a base: 16 × 15 ÷ 2 = 120

Area of sides:

37 × 15 = 555

37 × 16 = 592

37 × 20 = 740

Area of prism: 2 × 120 + 555 + 592 + 740 = 2127

Answer:

[tex]5y=-x+23\\[/tex]

Step-by-step explanation:

Since the equation of the line is perpendicular to the line y = 5x +6

we can use the formula:

[tex]m_1m_2=-1\\[/tex]

where m1 is the slope of the line we have and,

m2 is the slope of the line we need

so here m1 is 5 as we compare it with the slope-intercept form our slope is:

[tex]y=5x+6\\y=mx+b[/tex]

our m1 is 5 but we need m2 so plugging in the value we get m2 to be:

[tex]m_1m_2=-1\\5m_2=-1\\m_2=-1/5\\[/tex]

and now we have our m2, now furthermore since the line passes through the point (-2 , 5) it means the point must lie on the line and satisfy it. We can use this point and the slope m2 and find out the equation by the point-slope form equation:

[tex]y-y_1=m(x-x_1)\\y-5=-\frac{1}{5}(x-(-2))\\\\5(y-5)=(-1)(x+2)\\5y-25=-x-2\\5y=-x-2+25\\5y=-x+23\\[/tex]

Answer:

[tex]\sqrt{x^2+y^2+1}=18[/tex]

Step-by-step explanation:

We are given:

[tex]x^2=18x+y\qquad\qquad[1][/tex]

[tex]y^2=18y+x\qquad\qquad[2][/tex]

Subtracting [1] and [2]:

[tex]x^2-y^2=18x+y-(18y+x)[/tex]

Operating:

[tex]x^2-y^2=18x+y-18y-x[/tex]

Recall:

[tex]x^2-y^2=(x-y)(x+y)[/tex]

Substituting:

[tex](x-y)(x+y)=18x+y-18y-x[/tex]

Rearranging:

[tex](x-y)(x+y)=18x-18y-(x-y)[/tex]

[tex](x-y)(x+y)=18(x-y)-(x-y)[/tex]

Dividing by x-y (recall x≠y):

[tex]x+y=18-1=17[/tex]

[tex]x+y=17\qquad[3][/tex]

Now we add [1] and [2]:

[tex]x^2+y^2=18x+y+18y+x[/tex]

Rearranging:

[tex]x^2+y^2=18x+18y+x+y[/tex]

[tex]x^2+y^2=18(x+y)+(x+y)[/tex]

[tex]x^2+y^2=19(x+y)[/tex]

Substituting from [3]

[tex]x^2+y^2=19*17=323[/tex]

Adding 1:

[tex]x^2+y^2+1=324[/tex]

Taking the square root:

[tex]\sqrt{x^2+y^2+1}=\sqrt{324}=18[/tex]

Thus:

[tex]\mathbf{\sqrt{x^2+y^2+1}=18}[/tex]

Step-by-step explanation:

Let length is x and breadth is y.

The formula for the area and the perimeter of a rectangle is given by :

A = xy

P = 2(x+y)

Here, A = 8 mi² and P = 16 miles

Putting all the values,

xy = 8

y=8/x ......(1)

2(x+y) = 16

x+y = 8 .....(2)

Put equation (2) in equation (1) as follows :

[tex]x+\dfrac{8}{x}=8\\\\x^2+8=8x\\\\x^2-8x+8=0[/tex]

When we solve, we get :

x = 6.82 miles, 1.17 miles

Put the value of x in equation (1)

When x = 6.82 miles,

y = 8/6.82

y = 1.17 miles

When x = 1.17 miles,

y = 8/1.17

y = 6.82 miles

Hence, the dimension of the field is 6.82 miles and 1.17 miles.

Step-by-step explanation:

Answer:

The elevation is [tex]32.3^{o}[/tex].

Step-by-step explanation:

The home of the meerkat is 8 feet below the surface. So that the root of the stump would not be in his path, he dug 15 feet lower.

This can be represented by the sides of a right angled triangle. Applying the appropriate trigonometric function, let the elevation be represented by θ.

Then,

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

        = [tex]\frac{8}{15}[/tex]

Sin θ = 0.5333

⇒ θ = [tex]Sin^{-1}[/tex] 0.5333

      = 32.287

θ = [tex]32.3^{o}[/tex]

The elevation of the meerkat is [tex]32.3^{o}[/tex].

Answer:

It depends on your situation

Step-by-step explanation:

If you have a mixed fraction, for example: 5 23/3000 + 101 777/3000 you would have to make them irrational numbers and add them. Like so: 3000x5 = 15000. 15000+23 = 15023.  15023/3000. Same process but this time you get 303777/3000. You then add the numerators (top numbers) and you'll get the sum over 3000.

For regular fractions you simply add the numerators. If your denominators are not the same, you need to find a common term that both can fit into. If the denominators are not the same, no matter the size of the fraction, you cannot add it.

Answer:

  x = -7

Step-by-step explanation:

Substitute the given value and solve for x

  n(x) = -6x +2

  44 = -6x + 2

  42 = -6x . . . . . subtract 2

  -7 = x . . . . . . . divide by -7

n(x) will have the value 44 for x = -7.
