Answer:

Total no. of cups = 25+5n

Step-by-step explanation:

Given that,

Jayden begins with 25 cups with soil at the greenhouse.

Each day he will fill 5 cups more.

We need to find an algebraic expression to represent the number of cups he will have after n days.

Here, 5 cups increases with number of days and 25 cups remain fix.

Total number of cups after n days = 25 + 5n

Hence, the required answer is "25+5n".

Answer:

7x=42°

8x=48°

Step-by-step explanation:

Sum of all interior angles in a triangle=180°

90+8x+7x=180

90+15x=180

15x=180-90

15x=90

x=90/15

x=6

The measure of each acute angle is 42° and 48°.

If an angle is less than 90 degrees, then it is called an Acute angle. Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

Given there is a right triangle. since it's a right triangle angle one angle will always be 90 degrees.

Since the sum of all angles of any triangle is 180 degrees thus,

7x + 8x + 90 = 180

15x = 90

x  = 6

since each acute angles were 7x and 8x

hence those angles would be 42 and 48 degrees.

therefore, Each acute angle is 42° and 48° in size.

Answer:

[tex]m\angle 1=95^{\circ}[/tex]

Step-by-step explanation:

If we drew an auxiliary line parallel to line [tex]p[/tex] and line [tex]q[/tex] that intersects the vertex of [tex]\angle 1[/tex], we would form three angles, one of them being

The largest of these angles corresponds with the angle marked as [tex]148^{\circ}[/tex].

The angle on the bottom right corresponds with the angle next to the one marked as [tex]63^{\circ}[/tex]. Therefore, its measure is [tex]180-63=117^{\circ}[/tex].

Since there are [tex]360^{\circ}[/tex] in a circle, we can now write the following equation:

[tex]m\angle 1+117+148=360,\\m\angle 1=\fbox{$95^{\circ}\checkmark$}[/tex].

Answer:

95

Step-by-step explanation:

The way SkiffMacKinaw did this problem is the way it should be done. There is another way of doing it by extending both arms of <1 until they intersect p and q and solve the triangle hanging from p.

You then find the the angles of the triangle. The vertex angle is the supplement to <1.

This method works but it is not nearly as elegant as the original answer. This is one of the best awarded Brainliests I've seen lately.

Answer:

4 1/8 ounces

Step-by-step explanation:

Total bag of chocolate chips Mary has = 16 1/2 ounces

She will only use 1/4 of the bag for decorating a cake.

How many ounces will she use for decorating

Ounces used in decoration = 1/4 of 16 1/2

= 1/4 × 33/2

= (1*33)/(4*2)

= 33/8

= 4 1/8 ounces of chocolate chips

She will use 4 1/8 ounces of chocolate chips for decorating a cake

Answer:

Pounds of topsoil needs to order to cover an area of 169 square feet is 0.1275

Step-by-step explanation:

GIVEN: relation between the pounds of topsoil and area covered is ( a = 1325 p )

a represent area and b represent pounds of topsoil

To Find : pounds of topsoil needs to order to cover given area .

Solution : since here relation is given

                     a = 1325 p

            value of a = 169 square feet

so putting the value of a in above relation

       so ,  169 = 1325 p

             p = 169 / 1325  = 0.1275

So , pounds of topsoil needs to order to cover given area is 0.1275

  y = kx

where 'k' is the constant of proportionality.

Answer:

sides are 17 cm and 27 cm

Step-by-step explanation:

let the side be x then the adjacent side is x + 10

The perimeter is then

x + x + x + 10 + x + 10 = 88, that is

4x + 20 = 88 ( subtract 20 from both sides )

4x = 68 ( divide both sides by 4 )

x = 17

and x + 10 = 17 + 10 = 27

The sides of the parallelogram are 17 cm and 27 cm

Answer:

20 weeks

Step-by-step explanation:

If 20 kilograms of paper have already been recycled, and the goal is 40 kilograms, subtract the 20 kg from the 40 kg. You are left with a remaining 20 kg to recycle. If the new plan has the office recycling 1 kg a week, mulitply that by 20 kg to get 20 weeks.

It will take the office 20 weeks to reach the total 40 kg of recycled paper.

Answer:

[tex]m\angle N=57^{\circ}[/tex]

Step-by-step explanation:

From the isosceles-base theorem, the measure of the angles adjacent to the pair of congruent sides of the triangle are equal. Since the problem declares [tex]LM\cong LN[/tex], the remaining unknown angles are equal ([tex]m\angle N=m\angle M[/tex]). The sum of the interior angles of a triangle always add up to [tex]180^{\circ}$[/tex].

Therefore:

[tex]m\angle N\cdot 2+66=180,\\m\angle N\cdot 2=114,\\m\angle N=\fbox{$57^{\circ}$}[/tex] .

Answer:

LMN is rectangle in L so LMN= 180° ; ML=66°;N=?  N= 180°- 66°=114=114/2= 57° so N=57°

Step-by-step explanation:

When the angle at the top is close to 0 °, the two of the base get less than 180 °, or less than 90 ° for each. If the angle at the top is 60 °, the other two are: 180 - 60 = 120 °, and each is: 120/2 = 60 °.

Answer:

Sales price = $78

Original price = $61

Step-by-step explanation:

Ulian bought the shows for $120 at a specialty store. This discount store had it at $42 less. The price at the discount store is therefore:

= 120 - 42

= $78

The shoes at the discount store are 61% off and the discounted price is $78. Assume the original price is x. The original price will be:

x - (x * 61%) = 78

x - 0.61x = 78

0.39x = 78

x = 78/0.39

x = $200
