Step-by-step explanation:

Answer:

  301

Step-by-step explanation:

Assuming the proportion holds over longer distances, the ratios can be written ...

  peas/beans = p/133 = 43/19

  p = 133(43/19) = 301

301 peas are equal to 133 beans.

Answer:

1.75 + 1.25 + 1.50 + .75(3) = $6.75 total

Step-by-step explanation:

Make sure to multiply .75 x 3 because there are 3 bags of chips. That gives you $2.25 in chips to add to the hotdog, popcorn, and soda total.

okay so basically we see two rectangles right, so we can subtract the small from the big to leave the shaded region behind: so we take the area of the big rectangle first, (x+5)*4 and then we subtract the small area which is 2*2 so that we get an equation like this: (x+5)*4 - 4 --> 4x+20-4 --> 4x+16

Answer:

x=105, y=75 and z=105.....this is a map of parallellines and a transversal. ....angles x and 75 are supplementary angles x=180-75 ×=105...angles y and 75 are corresponding angles so, y=75..angles x and z are alternate exterior angles z=x

Answer:

c, a, a, c, a

Step-by-step explanation:

let me know if you want me to explain everyone, but I think you're more looking for the answer, so here they are(with short explanations)

11.c, 100. Vertical angles are congruent.

12.a, 70. Supplementary=180*. We know that B=110(from drawing). 110+70=180

13.a, 70. We know that a is 70 from question 12. vertical angles are congruent, so c=70

14.c, 90. from the attached image, we see that 12 and 3 makes 90* angle.

15.a, AY. Both have the letters AY in their names.

let me know if im correct!

Answer: 11,212

Step-by-step explanation:

base-ten numerals: 11,000 + 200 + 12+ = 11,212

number in expanded form:  11,212 =

+  10,000  

+ 1,000  

+ 200  

+ 10  

+ 2  

Answer: 200

Step-by-step explanation:

Let the unknown number be x.

Therefore, 20%*x = 40

20% as a fraction is 1/5.

Therefore x*(1/5) = 40

Multiply both sides by 5:

x = 200

Answer:

Answer:

x = 7

y = 2

--

x = 7

y = −x + 9

- Consider the second equation. Insert the known values of variables into the equation.

y = −7 + 9

Add −7 and 9 to get 2.

y = 2

The system is now solved.

x = 7

y = 2      ( 7,2 )

Answer:

2, because 100,000 is said one hundred thousand which means 1 is in the hundred thousand place, and the same applies to this number meaning 2 is in that place.

Triangle Proportionality Theorem

BD : DE = BA : AC

⇒ 6 : 10 = BA : 16

⇒ [tex]\mathsf{\dfrac{6}{10} = \dfrac{BA}{16}}[/tex]

⇒ [tex]\mathsf{BA=\dfrac{6}{10} \times16}[/tex]

⇒ BA = 9.6

AD = BA - BD

⇒ AD = 9.6 - 6 = 3.6 cm

This is a proportion question. That means that the ratios given are equal. There are 4 facts all together. 3 are given, you have to solve for the 4th. The procedure is the same every time.

Equation (proportion)

cost of apples 1.09/ Number of apples (3) = cost of nearly a dozen (x)/Number = 11.

1.09/3 = x / 11                 Cross Multiply

3x = 1.09 * 11                  Combine the right

3x = 11.99                       Divide by 3

3x/3 = 11.99/3      

x = 3.99

By solving a system of equations, we will see that the values of n and m are 3 and -4.

We need to get two values n and m such that:

n*m = -12

n + m = -1

So this is a system of equations, to solve it, we first need to isolate one of the variables in one of the equations. I will isolate n on the second equation:

n = -1 - m

Then, replacing that on the other equation we get:

(-1 - m)*m = -12

-m - m^2 = -12

-m^2 - m + 12 = 0

This is a quadratic equation, the solutions are given by Bhaskara's formula:

[tex]m = \frac{-(-1) \pm \sqrt{(-1)^2 - 4*(-1)*12} }{2*-1} \\\\m = \frac{1 \pm 7}{-2}[/tex]

Now, let's take the first solution for m:

m = (1 + 7)/-2 = -4

Then the value of n is the other solution, (or we can use the equation for n that we found above):

n = -1 - m = --1 - (-4) = 3

Then the two numbers are 3 and -4, meaning that the correct option is the first one.

[tex]\\ \rm\longmapsto 3x+28+x=180[/tex]

[tex]\\ \rm\longmapsto 4x+28=180[/tex]

[tex]\\ \rm\longmapsto 4x=152[/tex]

[tex]\\ \rm\longmapsto x\approx 38[/tex]

Let's assume that ,

x is the smaller angle

3x+28 is the larger angle

then,

ATQ,

x + 3x+28 = 180°

4x +28 = 180°

4x = 180°-28°

4x = 152°

x = 38°

putting the value of x in the larger angle

⇢3x +28 = 3 x 38° +28° = 142°

hence , the measure of the smaller angle is 38° & the larger one = 142°

With x = -12, Not applicable so x will be 10

Length → x + 5 → 10 + 5 → 15

Breath → x -3 → 10 - 3 → 7

Therefore,

Length : 15 cm

Breadth : 7 cm

Answer:

Given:

i) Length of rectangular shaped lamina = (x + 5) cm

ii) Breadth of rectangular shaped lamina = (x - 3) cm

ii) Area of a rectangle = length × breadth

⇒ area of rectangular shaped lamina = (x + 5)(x - 3) cm²

Given:

⇒ (x + 5)(x - 3) = 105

Expand:

⇒ x² - 3x + 5x - 15 = 105

Combine like terms:

⇒ x² + 2x - 15 = 105

Subtract 105 from both sides:

⇒ x² + 2x - 120 = 0

iv) Solve x² + 2x - 120 = 0

Rewrite:

⇒ x² + 12x - 10x - 120 = 0

Break into groups:

⇒ (x² + 12x) - (10x + 120) = 0

Factorize the parentheses:

⇒ x(x + 12) - 10(x + 12) = 0

Factor out common term:

⇒ (x - 10)(x + 12) = 0

Therefore,

x - 10 = 0  ⇒  x = 10

x + 12 = 0  ⇒  x = -12

As length is positive, x = 10 only

Therefore,

Length of rectangular shaped lamina = 15 cm

Breadth of rectangular shaped lamina = 7 cm

Step-by-step explanation:

Multiply .15 by 900
0.15 x 900 = 135
Hope this helps :)

Answer:

135

Step-by-step explanation:

To find 15% of a number, we can find 10% first then 5%

We can also turn 15% into a decimal by dividing 15 by 100: 15 ÷ 100 = 0.15 Now, we can treat 'of' as × and do 0.15 × 900 which is 135.
