Answer:

Your small pepperoni pizza would need to bake for 19 minutes

Step-by-step explanation:

Since the small pepperoni pizza has to bake 7 minutes longer that a small plain pizza which takes 12 minutes all you have to do is add 12 + 7

Answer:

1st picture (tri) = 16y+8

2nd picture (tri) = 12x-9

3rd picture (sq) = 21x+35

Step-by-step explanation:

Triangle area = (Base x Height) divided by 2

#1.)  16(2y+1) = 32y + 16            (32y+16)/2 = 16y+8

14/7 = 2

So,

-14/7 = -2

Check:

-2 x 7 = -14

Answer:

-2

Step-by-step explanation:

because 7 can go into 14 2 times and since the 14 is negative the answer is negative

Answer: f(x)

Step-by-step explanation:

Answer:

[tex]P=150+150t[/tex]

Step-by-step explanation:

Let P denotes the total cost and t denotes the time.

Total cost for 2 hours = $300

So,

Cost for 1 hour = [tex]\frac{300}{2} =\$150[/tex]

Also,

Fixed fee to use the studio = $150

The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio.

Therefore,

Total cost = Fixed fee to use the studio + Hourly fee for each hour in the studio

[tex]P=150+150t[/tex]

Answer:

x = 4

Step-by-step explanation:

Right Triangles

In right triangles, where one of the internal angles is 90°, the Pythagora's Theorem is satisfied:

If m is the hypotenuse of a right triangle, and p, q are the shorter sides or legs, then:

[tex]m^2=p^2+q^2[/tex]

If we need to calculate any of the legs, say, p:

[tex]p^2=m^2-q^2[/tex]

The figure below shows two additional variables z and h which will help us to find the value of x.

The triangle with sides 12, 36, z can be solved for z, being 36 the hypotenuse:

[tex]z^2=36^2-12^2=1296-144=1152[/tex]

The base of the triangle to the left is (36-x), the height is h, and the hypotenuse is z, thus:

[tex]h^2=z^2-(36-x)^2[/tex]

Substituting z:

[tex]h^2=1152-(36-x)^2[/tex]

The triangle to the right has dimensions x, h, and 12, and:

[tex]h^2=12^2-x^2[/tex]

Equating both expressions for h:

[tex]1152-(36-x)^2=12^2-x^2[/tex]

Expanding the squares:

[tex]1152-1296+72x-x^2=144-x^2[/tex]

Simplifying the x squared and operating:

-144+72x=144

Adding 144:

72x = 288

Solving:

x = 288 / 72 =4

x = 4

Answer:

A. solid to a liquid

Step-by-step explanation:

When you melt something it is always going to start off as a solid then turns into a liquid.

You can never melt something to make it a solid again like you cant melt water to make it ice, you can melt ice to make it water.

Hence, why the answer is A. solid to a liquid

Answer:

Historically, surnames evolved as a way to sort people into groups - by occupation, place of origin, clan affiliation, patronage, parentage, adoption, and even physical characteristics (like red hair). Many of the modern surnames in the dictionary can be traced back to Britain and Ireland.

Answer:

(3,5)(3,5)= 1

(-1,5)(-1,5)=1

Step-by-step explanation:

14. Question wise,

In ΔRST,

∠R=2x+5

∠S=x+1

∠T=7x-16

we know,

∠R+∠S+∠T=180 [sum of 3 angles of a triangle is 180°]

2x+5+x+1+7x-16=180

10x-10=180

10(x-1)=180

x-1=18

x=19

so,

∠R=(2×19)+5=43

∠S=19+1=20

∠T=(7×19)-16=117

15. Question wise,

In ΔABC,

∠A=∠C-13

∠B=4∠C-11

we know,

∠A+∠B+∠C=180 [,,]

∠C-13+4∠C-11+∠C=180

6∠C-24=180

6∠C=180+24

∠C=204÷6=34

so,

∠A=34-13=21

∠B=(4×34)-11=125

16. Question wise,

In ΔJKL

∠K=∠J+9

∠L=2∠J-21

we know,

∠J+∠K+∠L=180

∠J+∠J+9+2∠J-21=180

4∠J-12=180

4∠J=180+12

∠J=192÷4=48

so,

∠K=48+9=57

∠L=(2×48)-21=75
