Answer:

Rift =37.92 pounds

Terraza=2.08 pounds

9514 1404 393

Answer:

Step-by-step explanation:

Let t represent the number of pounds of Terraza blend required. Then 40-t is the number of pounds of Rift Valley blend needed. The cost of the mix will be ...

  13.50t +10.20(40 -t) = 10.37(40)

  3.30t = 6.8 . . . . . . . . . . . . . . . . . . . . subtract 408

  t = 6.8/3.30 = 68/33 = 2 2/33 ≈ 2.06061 . . . . pounds of Terraza

Then the quantity of Rift Valley blend required is ...

  40 -2 2/33 = 37 31/33 ≈ 37.93939 . . . . pounds of Rift Valley

Answer:

Choice D, x = 9

Answer:

Step-by-step explanation:

EG = EF + FG = 9 + x - 3 = 6 + x

AG = AH + HG = 6 +x - 2 =  4 + x

Intersecting secant theorem,

FG * EG = HG * AG

(x - 3)*(6 +x) = (x -2)(x + 4)

Use Foil method

6x + x²  - 18 - 3x = x² + 4x - 2x - 8

x² + 3x  - 18 = x² + 2x - 8

x² - x² + 3x - 2x = -8 + 18

               x = 10

Answer:

  y - 155 = 9(x -15)

Step-by-step explanation:

The given points are ...

  (days, coins) = (15, 155) and (22, 218)

The slope is given by the slope formula:

  m = (y2 -y1)/(x2 -x1) = (218 -155)/(22 -15) = 63/7 = 9

The point-slope form is for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Here, we have m=9 and (h, k) = (15, 155), so the equation can be written ...

  y - 155 = 9(x -15)

b=16*x⁴y³z²=4*4*x⁴*y³*z²

hcf(a,b)=4*x³*y*z²=4x³yz²

a and b are correct

c is wrong

d can't be decided, because it can be true for one case, but not for others.

so only go for a and b

Answer:

B. The function is linear. (A and D COULD work)

Step-by-step explanation:

If the graph of a direct variation function has a slope of -3, then we know that the function is linear, and that m in the equation y = mx + b is -3. However, option A could be incorrect since we don't know if there is a y-intercept or not. C is wrong because of -3 being the slope, and D would only be true if A was also correct. So that leaves B. (If you know that there is more than one option, then A, B, and D are correct.)

[tex]\frac{M(3)+M(2)}{2} =\frac{[-2(3)^{2}] +[-2(2)^{2}]}{2}=\frac{(-2)(9)+(-2)(4)}{2}=\frac{-18-8}{2}=\frac{-26}{2}=-13[/tex]

Given:

[tex]a=1.6,b=\dfrac{1}{-2},c=\dfrac{-5}{-7}[/tex]

To verify:

[tex]a(b-c)=ab-ac[/tex] for the given values.

Solution:

We have,

[tex]a=1.6,b=\dfrac{1}{-2},c=\dfrac{-5}{-7}[/tex]

We need to verify [tex]a(b-c)=ab-ac[/tex].

Taking left hand side, we get

[tex]a(b-c)=1.6\left(\dfrac{1}{-2}-\dfrac{-5}{-7}\right)[/tex]

[tex]a(b-c)=1.6\left(-\dfrac{1}{2}-\dfrac{5}{7}\right)[/tex]

Taking LCM, we get

[tex]a(b-c)=1.6\left(\dfrac{-7-10}{14}\right)[/tex]

[tex]a(b-c)=\dfrac{16}{10}\left(\dfrac{-17}{14}\right)[/tex]

[tex]a(b-c)=\dfrac{8}{5}\left(\dfrac{-17}{14}\right)[/tex]

[tex]a(b-c)=-\dfrac{68}{35}\right)[/tex]

Taking right hand side, we get

[tex]ab-ac=1.6\times \dfrac{1}{-2}-1.6\times \dfrac{-5}{-7}[/tex]

[tex]ab-ac=-\dfrac{16}{20}-\dfrac{8}{7}[/tex]

[tex]ab-ac=-\dfrac{4}{5}-\dfrac{8}{7}[/tex]

Taking LCM, we get

[tex]ab-ac=\dfrac{-28-40}{35}[/tex]

[tex]ab-ac=\dfrac{-68}{35}[/tex]

Now,

[tex]LHS=RHS[/tex]

Hence proved.

[tex]\boxed{\sf Option \ C \ is \ correct .}[/tex]

Step-by-step explanation:

We need to tell which of the given inequality is true . The given inequalities are ,

[tex]\sf A)\pi + 8 <11\\\\\sf B) \dfrac{\pi}{8} > 2 \\\\\sf C) 3\pi > 9 \\\\\sf D) 2\pi - 1 < 5 [/tex]

Let's check the options one by one .

Option A :-

[tex]\sf\longrightarrow \pi + 8 < 11[/tex]

Subtract 8 to both sides ,

[tex]\sf\longrightarrow \pi < 11 - 8 [/tex]

Simplify ,

[tex]\sf\longrightarrow \pi < 3[/tex]

We know the approximate value of pi 3.14 . But the inequality says pi is less than 3 . Therefore the given inequality is incorrect .

______________________________________

Option B :-

[tex]\sf\longrightarrow \dfrac{\pi}{2} > 2 [/tex]

Multiply both sides by 2 ,

[tex]\sf\longrightarrow \pi > 4 [/tex]

We know the approximate value of pi 3.14 . But the inequality says pi is more than 4 . Therefore the given inequality is incorrect .

______________________________________

Option C :-

[tex]\sf\longrightarrow 3 \pi > 9[/tex]

Divide both sides by 3 ,

[tex]\sf\longrightarrow \pi < 9/3[/tex]

Simplify ,

[tex]\sf\longrightarrow \pi > 3 [/tex]

We know the approximate value of pi 3.14 .And the inequality says pi is more than 3 . Therefore the given inequality is correct .

Option C is correct .

(a) Dilation is the process of extending the line segment AB to the longer one A'B'. The scale factor has to be larger than 1, and also it has to be positive.

(b) To get the dilation factor, you should first compute the length of AB, then compare it to the length of A'B'.

A is the point (-4, 2), and B is the point (2, -4). So the length of AB is

√((-4 - 2)² + (2 - (-4))²) = √((-6)² + 6²) = √72

A' is the point (-8, 4) and B' is (4, -8). The coordinates of A' and B' are twice the coordinates of A and B, so the distance is

√((2(-4) - 2(2))² + (2(2) - 2(-4))²) = √(2²×72) = 2√72

Then the dilation factor is

(2√72) / √72 = 2

4/7 / 7/8

32/49

The tons of concrete are required to cover the entire bridge is 32/49 tons.

A fraction is a non-integer that is made up of a numerator and a denominator. An example of a fraction is 4/7.

To determine this value, divide 4/7 by 7/8

4/7 ÷ 7/8

4/7 x 8/7 = 32/49 tons

Answer:

? = 14

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan ? = 8/33

Taking the inverse tan of each side

tan ^-1 ( tan ?) = tan ^-1 ( 8/33)

? =13.62699

To the nearest degree

? = 14

Answer:

14

Step-by-step explanation:

We can solve for either x or y first, but we will choose to solve for x first. The side with length of 8 is opposite the angle x and the side with length of 33 is adjacent. Since we have opposite and adjacent sides, we will use the tangent ratio.

tan(x)= opposite/adjacent

tan(x)= 8/33

To find the measure of angle x, we will use the inverse tan function.

x=tan⁻¹(8/33)= 14
