Answer:

A. 36 x 4 = ?

Answer:

a. 36 x 4

If Justin has 4 times as many coins as Ella, who has 36 coins, he would have 144 coins.

Therefore, 36 x 4 = 144

Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

A recipe requires 1 (2/3) cups of sugar.

That is 1 recipe requires = 1(2/3) cups of sugars

                                        = 5/3 cups of sugar

Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :

1 recipe requires = 5/3 cups of sugar

1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar

3/2 recipe requires = (5/3) x (3/2) cups of sugar

3/2 recipe requires = 5/2 cups of sugar or 2.5  cups of sugar.

Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

Explanation:

Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.

That y value is the input to the f(x) function.

Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.

Answer:

1 inch of drawing = 45 feet

Step-by-step explanation:

Given that:

Length between the bases on a baseball field = 90 feet

As per the scale drawing, the distance between the bases is equal to 2 inches.

To find:

Length of one inch on the drawing is equal to actual length of how many feet?

Solution:

First of all, let us learn about the scale drawings.

Scale drawings are a way to represent the big real world measurements on a paper.

Therefore, small measurements are used to represent the bigger real world measurements.

Here, it is given that:

2 inches on scale is equal to 90 feet of actual length.

Therefore,

1 inch on scale is equal to [tex]\frac{90}{2}[/tex] = 45 feet of actual length.

Therefore, 1 inch of drawing = 45 feet

Answer: The size and shape will only change when the transformation being made to the figure is a dilation. Since it is only being translated, its image and preimage are still congruent in size.

Step-by-step explanation:

For dilation, the size and shape of a figure only changes when transformed while if translated, the image and preimage  of the figure remains congruent in size.

Transformation is a way of changing the size and shape of an object in an xy-plane

Some of the transformation techniques used are translations and dilation

Step-by-step explanation:

Answer:

a) 1.24 g/ml

b) 2.4%

Step-by-step explanation:

density = mass/volume

volume of sample = 28.4 - 15 = 13.4mL

density = 13.4/10.8

=1.24 g/ml

percent error

1.27 - 1.24 = 0.03

0.03/1.24 *100% = 2.4% error

Answer:

Independent Variable: Number of bagels bought

Dependent Variable: Total cost because it depends on the number of bagels bought.

Function: N(x)=1.75x

So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5

Step-by-step explanation:

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is V(x) =1.75x.

So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.

Just do minus two, and you will get 27-100=-73

Step-by-step explanation:

Answer/ explanation: -10 for sure :)

The next two terms after -40 in this pattern are 60 and -160.

The difference between every two subsequent words in a sequence is the same; this is known as an arithmetic progression (AP). An equation for the previous block of the AP may be derived from this kind of development. For instance, the sequence 2, 6, 10, 14,... is a mathematical progression (AP) because it fits a pattern where every other number is acquired by adding 4 to the respective period.

The given data is,

-10, 20, -40

From -10 to 20 it is multiplied by 2 with a positive sign, and from 20 to -40 it is multiplied by 2 with a negative sign. Similarly, the next two numbers are 80 and -160.

Answer:

(4,5)

Explanation: 9-5=4, 4+1=5

Given:

[tex]\dfrac{5}{6+2i}[/tex]

To find:

The  quotient in the form a + bi.

Solution:

We have,

[tex]\dfrac{5}{6+2i}[/tex]

Multiply numerator and denominator by 6-2i.

[tex]=\dfrac{5\times (6-2i)}{(6+2i)\times (6-2i)}[/tex]

[tex]=\dfrac{5(6)+5(-2i)}{6^2+(2i)^2}[/tex]

[tex]=\dfrac{30-10i}{36+4i^2}[/tex]

[tex]=\dfrac{30-10i}{36+4(-1)}[/tex]    [tex][\because i^2=-1][/tex]

On further simplification, we get

[tex]=\dfrac{30-10i}{36-4}[/tex]

[tex]=\dfrac{30-10i}{32}[/tex]

[tex]=\dfrac{30}{32}-\dfrac{10i}{32}[/tex]

[tex]=\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex]

Therefore, the form a+bi is [tex]\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex], where, [tex]a=\dfrac{15}{16}[/tex] and [tex]b=(-\dfrac{5}{16})[/tex].

The value of [tex]y[/tex] will be [tex]4\sqrt{3}[/tex] .

Triangle is a three sides two dimensional surface having three angles.

We have,

[tex]\triangle MRN[/tex] , [tex]\triangle RSM[/tex] and [tex]\triangle RSN[/tex],

And, [tex]NS =6,\ SM=2,\ RM=x,\ NR=y,\ RS=z[/tex]

Now,

We have right angle [tex]\triangle MRN[/tex],

Using Pythagoras theorem,

[tex]x^2+y^2=8^2[/tex]

[tex]x^2+y^2+=64\[/tex]     [tex].....(i)[/tex]

Now, We have right angle [tex]\triangle RSN[/tex],

Again Using Pythagoras theorem,

[tex]z^2+6^2=y^2[/tex]

⇒[tex]z^2=y^2-36[/tex]     [tex].....(ii)[/tex]

Now, We have right angle [tex]\triangle RSM[/tex],

Again Using Pythagoras theorem,

[tex]z^2+2^2=y^2[/tex]

⇒[tex]z^2=x^2-4[/tex]     [tex].....(iii)[/tex]

Now comparing equation [tex](ii)[/tex] and equation  [tex](iii)[/tex],

We get,

[tex]x^2-4=y^2-36[/tex]

We get,

[tex]x^2-y^2=-36+4[/tex]

[tex]x^2-y^2=-32[/tex]     [tex].....(iv)[/tex]

Now,

Adding equation [tex](i)[/tex] and equation  [tex](iv)[/tex], i.e.

[tex]x^2+y^2+=64[/tex]

[tex]x^2-y^2=-32[/tex]

We get,

[tex]2y^2=96[/tex]

[tex]y^2=48[/tex]

[tex]y=\sqrt{48}[/tex]

[tex]y=4\sqrt{3}[/tex]

So, the value of [tex]y[/tex] is [tex]4\sqrt{3}[/tex]

Hence, we can say that the value of [tex]y[/tex] will be [tex]4\sqrt{3}[/tex]  which is given in option (b).
