Answer:

A: $45 for 3 days

B: c=d(15)

Step-by-step explanation:

A: If 105 is the cost for 7 days and we want to find the cost for only 3 we have to find the cost for one day to start with so, 105 divided by 7 which is $15 so its 15 dollars a day then you multiply 15 by the number of days we want (3) and you get $45.

Answer:

x = 4

Step-by-step explanation:

If a line is parallel to a side of the triangle and intersects the other 2 sides then it divides those sides proportionally, that is

[tex]\frac{2}{4}[/tex] = [tex]\frac{x-1}{6}[/tex] ( cross- multiply )

4(x - 1) = 12 ( divide both sides by 4 )

x - 1 = 3 ( add 1 to both sides )

x = 4

Answer:

AC = XY

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.

Two triangles are said to be congruent if all the three sides and three angles of one triangle is equal to the three sides and three angles of the other triangle.

In Δ ABC and ΔXYZ ,∠B=∠X=90. This means that triangle ABC and triangle XYZ are right angled triangle since one of their angles is 90 degrees.

The hypotenuse is the side opposite to right angle (90 degrees).

Therefore AC is the hypotenuse of triangle ABC and YZ is the hypotenuse of triangle XYZ.

If the hypotenuse and one leg of a right angled triangle is equal to the hypotenuse and leg of another right angled triangle, then the two triangles are congruent by RHS rule.

Since BC = XY, for Δ ABC congruent to ΔXYZ by R.H.S condition, the hypotenuse have to be equal, i.e. AC = XY

What is Simple interest?

The cost of borrowing money without accounting for the effects of compounding is called Simple interest.

Given that;

Principal amount (P) = 3,000

Rate (R) = 5.5%

Time (T) = 21 month = 1 9/12 years

Now, The formula for the interest is;

Interest = P × R × T / 100

Where, P is the principal amount of money, R is the interest rate, T is the time.

Substitute all the values we get;

Interest = 3,000 × 5.5 × 1 9/12 / 100

            = 55 × 21 / 4

            = 288.75

Thus, Nina's grandmother earn $288.75 interest after 21 months.

Answer:

2^6

Step-by-step explanation:

The equivalent of the expression, 2 x 2 x 2 x 2 x 2 x 2  is 2⁶.

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.

An equivalent expression is an expression that has the same value or worth as another expression, but does not look the same.

Therefore, let's simplify the expression to find its equivalent as follows:

2 x 2 x 2 x 2 x 2 x 2 = 2⁶

Answer: Lower-right corner  [tex]3^7 \times \frac{1}{3^4}[/tex]

Explanation:

We use the rule that

[tex]a^{-b} = \frac{1}{a^b}[/tex]

The negative exponent tells us to apply the reciprocal if we want the exponent to be positive.

In this case, a = 3 and b = 4

So,

[tex]a^{-b} = \frac{1}{a^b}\\\\3^{-4} = \frac{1}{3^4}[/tex]

which is why overall,

[tex]3^7\times 3^{-4} = 3^7 \times \frac{1}{3^4}[/tex]

The numbers that make the result a whole number are 20 for x and 2 for the gap number.

The first step would be to identify the result of this expression and then add the number that can make this result a whole number.

Answer:

B. The value of y can be negative.

Step-by-step explanation:

The value of y can be negative, which means the beekeeper wasn't able to sell a lot of jars that could compensate the amount he paid for the booth. It also means he didn't have any profit, rather, he incurred a loss.

For example, if the beekeeper sold only 5 jars of honey, the solution will look like this:

Let x be the number of jars of honey the beekeeper sold.

This means that the beekeeper has a loss of $5.

Answer:

y =3 x

Step-by-step explanation:

The standard equation of a line in point slope form is expressed as;

y -y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given the line 3x - y = 5

Get the slope

- y = -3x + 5

y = 3x - 5

Slope m  = 3

Substitute m = 3 and (-1, -5) into the given formula

y - (-5) = 3(x-(-1))

y+5 = 3(x+1)

y + 3 = 3x+3

y = 3x + 3 - 3

y = 3x

Hence the equation in slope intercept form is y =3 x

Answer:

The slope is 3.

Step-by-step explanation:

The equation for slope is either [tex]\frac{y2-y1}{x2-x1}[/tex] or [tex]\frac{y1-y2}{x1-x2}[/tex]. So this should be [tex]\frac{19-13}{6-4}[/tex], which is 3.
