Answer:

A

Step-by-step explanation:

The answer is A because in the triangle, the two smaller sides added up have to be more than the bigger side, or equal, if it is a right triangle. so 4 is the smallest 4+6=10, so it does not work, but lets see if it is a right triangle

4^2+6^2=16+36=52. it would have to equal 100 to be a right triangle. Use Pythagorean thereon.

For a triangle, the any two sides must be greater than the third side.The measure of AC cannot be equal to 4

A triangle has three sides and angle. For a triangle, the any two sides must be greater than the third side.

Given the following parameters

AB = 10 and

BC = 6

The measure of AC must be 8 for the theorem above to be true

6 +8 > 10

6 +10 > 8

10 + 8 > 6

Hence the measure of AC cannot be equal to 4

Hey There!!

Your answer will be 1.

Step-by-step explanation:

If the coordinates of the point D' are (x, y), then, after translation, it will be

D(x + 6, y - 4).

that is 6 units right and 4 units down

It is given that the point before translation is D'(3, 5).

So, x + 6 = 3 + 6 = 9 and

y - 4 = 5 - 4 = 1

So, the y coordinate of point D after translation is 1.

The statement

Twice the difference of a number and 8 is written as

2( b - 8)

The expression is greater than - 21 so we represent it by the > sign

So we have

2( b - 8) > - 21

Expand

2b - 16 > - 21

2b > - 21 + 16

Answer:

12x=10(25+x)

Step-by-step explanation:

Jim's rate=x

Pete's rate=y

Jim and Pete lays the same number of tiles.

So we have,

12x=10y

Pete's can lay 25 more tiles than Jim per hour

We have

y=25+x

Substitute y=25+x into 12x=10y

12x=10y

12x=10(25+x)

12x=250+10x

12x-10x=250

2x=250

x=250/2

=125

x=125

12x=10(25+x) is the equation used to find the rate that Jim can lay tiles

Answer:

-3, 5/2

Step-by-step explanation:

What are the roots of the function y = 4x2 + 2x – 30?

To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.

Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)

Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)

Use the zero product property and set each factor equal to zero and solve.

x+3=0      2x-5 = 0

x = -3, 5/2

The roots of the function are -3, 5/2.

Hope this helped!

The roots of the function y = 4x² + 2x - 30 are -3, 5/2 after using the zero product property.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

y = 4x² + 2x - 30

To find the roots of the quadratic equation plug y = 0

4x² + 2x - 30 = 0

4x² + 12x - 10x - 30 = 0

4x(x + 3) - 10(x + 3) = 0

(x + 3)(4x -10) = 0

x + 3 = 0  or  4x - 10 = 0

x = -3 or x = 10/4 = 5/2

Thus, the roots of the function y = 4x² + 2x - 30 are -3, 5/2 after using the zero product property.

#SPJ2

Answer:

To use up the remaining 3cups of apples, she would need 3cups of oranges, 12cups of strawberries, 6cups of cherry and 9 cups of grape.

Step-by-step explanation:

This is a continuation of the question on the recipe for making salad. The initial recipe from her grandmother is stated below (found on brainly, ID 6786167).

The fruit salad recipe calls for one part apple, one part orange, four parts strawberry, two parts cherry, and three parts grape.

Priscilla uses the same measuring cup to measure all of the fruit, so one part is equal to one cup of diced fruit.

Number of cups required for each fruit in the original recipe:

apple = 1 cup , orange = 1 cup, strawberry = 4cups, cherry = 2cups, grape = 3cups

Original ratios of the cup of fruit respectively = 1:1:4:2:3

Total number of cups required in the original recipe: 1+1+4+2+3 = 11 cups

Now for this question, 3 cups of apples are remaining. And we want to find number of other fruits she needs in order to use up the remaining apples.

To do this we would use the ratios of the cup of fruit.

When we had 1 apple, the ratio was = 1

Now we have 3apples, the new ratio = 3×original ratio

=3×1 = 3

This means we would multiply each of the fruit ratios by 3

For orange, new ratio = 3×1 = 3

For strawberries, new ratio = 3×4 = 12

For cherry, new ratio = 3×2 = 6

For grape, new ratio = 3×3 = 9

To use up the remaining 3cups of apples, she would need 3cups of oranges, 12cups of strawberries, 6cups of cherry and 9 cups of grape.

Answer:

Priscilla uses one part orange, four parts strawberry, two parts cherry, and three parts grape for every one part apple. So, to use three times the quantity of apples, she will have to use three times the quantity of the other fruits as well. She needs three parts orange, twelve parts strawberry, six parts cherry, and nine parts grape for three parts apple.

Answer:

A) 3,276 ways.

Step-by-step explanation:

In this case, choosing February 1, February 12, and February 20 would be the same thing as choosing February 12, February 1, and February 20. So, since order does not matter, we will use a combination to solve the question.

The formula for combinations is...

n! / [r!(n - r)!], where n = the number of days in February (28) and r = the number of days you are choosing (3).

28! / [3! * (28 - 3)!]

= 28! / (6 * 25!)

= (28 * 27 * 26) / 6

= (14 * 9 * 26) / 1

= 14 * 9 * 26

= 126 * 26

= A) 3,276.

Question:

The volume of a right circular cone with both diameter and height equal to h is 250/7 cm³.

What is the value of h?

Answer:

A. 5

Step-by-step explanation:

Given

Solid Shape: Cone

Volume = 250/7

Diameter = Height

Required

Find the height of the cone

Provided that the diameter (D) and the height (h) are equal; This implies that

D = h ------ (1)

Also, Diameter (D) = 2 * Radius (r)

D = 2r

Substitute 2r for D in (1)

2r = h

Multiply both sides by ½

½ * 2r = ½ * h

r = ½h

Volume of a cone is calculated by;

Volume = ⅓πr²h

⅓πr²h = 250/7

Substitute ½h for r

[tex]\frac{1}{3} * \pi * (\frac{1}{2}h)^2 * h = \frac{250}{7}[/tex]

Take π as 22/7, the expression becomes

[tex]\frac{1}{3} * \frac{22}{7} * (\frac{1}{2}h)^2 * h = \frac{250}{7}[/tex]

Open the bracket

[tex]\frac{1}{3} * \frac{22}{7} * \frac{1}{4}h^2 * h = \frac{250}{7}[/tex]

Multiply both sides by 7

[tex]7 * \frac{1}{3} * \frac{22}{7} * \frac{1}{4}h^2 * h = \frac{250}{7} * 7[/tex]

[tex]\frac{1}{3} * 22 * \frac{1}{4}h^2 * h = 250[/tex]

Multiply both sides by 3

[tex]3 * \frac{1}{3} * 22 * \frac{1}{4}h^2 * h = 250 * 3[/tex]

[tex]22 * \frac{1}{4}h^2 * h = 750[/tex]

Multiply both sides by 4

[tex]4 * 22 * \frac{1}{4}h^2 * h = 750 * 4[/tex]

[tex]22 * h^2 * h = 3000[/tex]

[tex]22 * h^3 = 3000[/tex]

Divide both sides by 22

[tex]h^3 = \frac{3000}{22}[/tex]

[tex]h^3 = 136.36[/tex]

Take cube root of both sides

[tex]h = \sqrt[3]{136.36}[/tex]

[tex]h = 5.15[/tex]

[tex]h = 5[/tex] (Approximated)

1. Homeowners insurance policy

2. Pet insurance policy

Step-by-step explanation:

Homeowners' insurance policy is an insurance policy that covers the damages made to an insured place of residence. The insurance company takes care of damages that occur inside, and outside the house. Damaged furnishing as well as accidents that occur within the house are also catered to by the insurance company. The policyholder pays a deductible out of the total amount of money for the claims of damages while the insurance company takes care of the additional cost. So Selina would resort to a homeowners' insurance policy for her house so as to cover the loss in case of a natural calamity.

The Pet insurance policy also takes care of the veterinary costs of pets just in case they fall ill or suffer any other accidents. Selina would buy a pet insurance policy to take care of this potential problem.

Answer:

============================================================

Explanation:

Pick two points on this diagonal line where (x,y) has whole number coordinates. Two such points that fit the description are (-3,2) and (1,-1)

Use the slope formula to find the slope through these points

m = (y2-y1)/(x2-x1)

m = (-1-2)/(1-(-3))

m = (-1-2)/(1+3)

m = -3/4 is the slope

-------------------------

Extra info:

It doesn't matter which two points you pick as you'll always get the same slope value. Of course, the points must be on the diagonal line.

The negative slope indicates the line goes downhill as you move from left to right.

slope = rise/run = -3/4

rise = -3, a negative rise means we go down 3 units

run = 4, we go to the right 4 units

so we go down 3 and over to the right 4. This will move us from (-3,2) to (1,-1)

Answer:

[1  26  7]

Step-by-step explanation:

[1  26  7]

one row three column

==========================================================

Explanation:

We have a 1x3 matrix multiplied with a 3x3 matrix. This is a valid operation since the number of columns in the first matrix matches with the number of rows in the second matrix.

The resulting answer matrix will be 1x3 as it takes the number of rows of matrix A and the number of columns from matrix B, helping forming the answer matrix C.

The answer matrix looks like

[tex]C = \begin{bmatrix}x & y & z\end{bmatrix}[/tex]

where x, y and z are placeholders for actual numbers.

To get the value of x, we apply the dot product of the left matrix with the first column of the right matrix

x = (-1)(3)+(2)(2)+4(0) = -3+4+0 = 1

We'll do a similar set of steps to find y

Apply the dot product on the second column this time

y = (-1)(6)+2(4)+4(6) = -6+8+24 = 26

and the third column as well

z = (-1)(1)+2(0)+4(2) = -1+0+8 = 7

Since x = 1, y = 26 and z = 7, we can say

[tex]C = \begin{bmatrix}x & y & z\end{bmatrix}[/tex]

becomes

[tex]C = \begin{bmatrix}1 & 26 & 7\end{bmatrix}[/tex]
