Answer:

Step-by-step explanation:

Given the ratio of blueberries to strawberries in a fruit salad to be 4:3. The total ratio = 4+3 = 7

If there are 45 strawberries in the salad then we can first calculate the total mixture of both as shown;

amount of strawberries = 3/7 * x = 45

x is the total amount of mixture

from the expression;

3x/7 = 45

cross multiply

3x = 7*45

3x = 315

x = 315/3

x = 105

The amount of blueberries present = 105 - 45 = 60

Hence the amount of blueberries present is 60 blueberries

a= 38.85

Step-by-step explanation:

Answer:

[tex]\boxed {a = 38.85}[/tex]

Step-by-step explanation:

Solve for the value of [tex]a[/tex]:

[tex]\frac{a}{3.5} - 4.8 = 6.3[/tex]

-Add both sides by [tex]4.8[/tex]:

[tex]\frac{a}{3.5} - 4.8 + 4.8 = 6.3 + 4.8[/tex]

[tex]\frac{a}{3.5} = 11.1[/tex]

-Multiply both sides by [tex]3.5[/tex]:

[tex]a = 11.1 \times 3.5[/tex]

[tex]\boxed {a = 38.85}[/tex]

Therefore, the value of [tex]a[/tex] is [tex]38.85[/tex].

Answer:

She paid $8,25 per pound

Step-by-step explanation:

Given

[tex]Weight = 1.6\ lb[/tex]

[tex]Total= \$13.20[/tex]

Required

Determine the amount paid per pound

To do this, we simply divide the amount by the weight of Almonds.

[tex]Amount = \frac{Total}{Weight}[/tex]

[tex]Amount = \frac{\$13.20}{1.6\ lb}[/tex]

[tex]Amount = {\$8.25/\ lb[/tex]

Hence, she paid $8,25 per pound

Answer:

C is the answer.

C has a common difference of "2"

Step-by-step explanation:

Answer:

The ramp must be placed 13.08 feet from the base of the house.

The angle the ramp will make with the ground is 20.92°.

Step-by-step explanation:

An illustrative diagram for the scenario is shown below.

In the diagram, d represents the distance of the door from the ground, r represents the length of the ramp and x represent the distance of the ramp from the base of the house.

To determine how far away from the base of the house the ramp must be placed, that is to determine x in the diagram.

The diagram is a right angle triangle and x can be determine using the Pythagorean theorem which states " the square of the hypotenuse equals sum of the squares of the other two sides"

In the diagram, the hypotenuse is r

∴ r² = d² + x²

r = 14 ft

d = 5 ft

∴ 14² = 5² + x²

196 = 25 + x²

Then, x² = 196 - 25

x² = 171

x = √171

x = 13.08

Hence, the ramp must be placed 13.08 feet from the base of the house.

Now, to determine what angle the ramp will make with the ground, that is θ in the diagram.

From the formula

Sinθ = Opposite / Hypotenuse

In the diagram, opposite = d = 5ft

and Hypotenuse = r = 14ft

∴ Sinθ = 5ft / 14ft

Sinθ = 0.3571

∴ θ = Sin⁻¹(0.3571)

θ = 20.92°

Hence, the angle the ramp will make with the ground is 20.92°.

Answer:

Solution of [tex]14 + 3n = 8n - 3(n-3)[/tex] => x = 5/2

Solution of [tex]22x + 11 = 4x - 7[/tex] => x=-1

Step-by-step explanation:

We will solve the equations one by one

So,

[tex]14 + 3n = 8n - 3(n-3)[/tex]

Applying Distributive property

[tex]14 + 3n = 8n - 3n+9\\14+3n = 5n+9[/tex]

Subtraction property of equality (Subtracting 14 from both sides)

[tex]14+3n-14 = 5n+9-14\\3n = 5n-5[/tex]

Subtraction property of equality (Subtracting 5n from both sides)

[tex]3n-5n = 5n-5-5n\\-2n = -5[/tex]

Division property of equality (Dividing both sides by -2)

[tex]\frac{-2n}{-2} = \frac{-5}{-2}\\n = \frac{5}{2}[/tex]

Second Equation:

[tex]22x + 11 = 4x - 7[/tex]

Subtraction property of equality (Subtracting 11 from both sides)

[tex]22x + 11-11 = 4x - 7-11\\22x = 4x-18[/tex]

Subtraction property of equality (Subtracting 4x from both sides)

[tex]22x-4x = 4x-18-4x\\18x = -18[/tex]

Division property of equality (Dividing both sides by 18)

[tex]\frac{18x}{18} = \frac{-18}{18}\\x = -1[/tex]

Hence

Solution of [tex]14 + 3n = 8n - 3(n-3)[/tex] => x = 5/2

Solution of [tex]22x + 11 = 4x - 7[/tex] => x=-1

Answer: 54%

Step-by-step explanation:

The relative frequency of landing on heads is 0.54 or 54%.

Given that Jamie tossed a coin 50 times.
Head showed for 27 times.

Tails showed for 23 times.

We need to find the relative frequency of landing on heads,

The relative frequency of an event is calculated by dividing the number of times the event occurred by the total number of trials or occurrences.

In this case, Jamie tossed a coin 50 times, and it landed on heads 27 times.

To find the relative frequency of landing on heads, we divide the number of times the coin landed on heads (27) by the total number of tosses (50):

Relative Frequency of landing on heads = Number of heads / Total number of tosses

Relative Frequency of landing on heads = 27 / 50

Simplifying this fraction, we get:

Relative Frequency of landing on heads = 0.54

This means that, based on the given data, the coin landed on heads approximately 54% of the time in the 50 tosses performed by Jamie.

Therefore, the relative frequency of landing on heads is 0.54 or 54%.

Answer:

(a) M + W = Indoor= [26 55] Outdoor = [32 49]

(b) The value indicates the sum of the indoor volunteers ages 18-39 so the Value would be, 34.

(c) M – W = Indoor = [8 15] Outdoor = [-16 3]

(d) This value indicates the difference of the volunteers indoors 40. So the value would be 15.

Step-by-step explanation:

If this is wrong my apologies i tried LOL

but i will let you know when i get the results back asap!

The value of the element t11 is 34 and the value of the element at d12 is 15.

Two matrices are equal if and only if their shapes are same, and they've got the same elements for each corresponding row and column positions.

M + W = Indoor= [26 55] Outdoor = [32 49]

The value indicates the sum of the indoor volunteers ages 18-39,

Therefore, the Value would be, 34.

To create a matrix by subtracting the women's matrix from the mens matrix.

Now the difference;

M – W = Indoor = [8 15] Outdoor = [-16 3]

This value indicates the difference of the volunteers indoors 40 so

Therefore the value would be 15.
