ngle 6 is 30 degrees. Angle 6 and angle 7 are vertical angles, so they are equivalent. Also, Angle 7 and angle 5 are supplementary, so angle 5 is 180-30 = 150 degrees.i think it is the answer
When measuring distance 43 peas are approximately equal to 19 beans. How many peas are equal to 133 beans?
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.
Three pounds of apples costs $1.09. How much will 11 pounds of apples cost? Round to the nearest cent.
Answer:
Step-by-step explanation:
Comment
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

11. Write a formula for the area of the shaded region in terms of x.

x + 5
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
Solve all 4 Questions . 50 Points + Brainelist
i)
length of rectangle : x + 5ii)
breadth of rectangle : x - 3iii)
area of rectangle = length * breadth105 = (x + 5)(x - 3)105 = x² + 2x - 15 x² + 2x - 15 - 105 = 0 x² + 2x - 15 - 105 = 0 x² + 2x - 120 = 0iv)
x² + 2x - 120 = 0x² + 12x -10x - 120 = 0x( x + 12) -10 (x +12) = 0(x-10)(x+12)x = 10, -12With 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:
The length of the rectangular shaped lamina is 5 cm more than the length of the square shaped lamina.The breadth of the rectangular shaped lamina is 3 cm less than the length of the square shaped lamina.x = side length of squarei) 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:
area of rectangular shaped lamina = 105 cm²⇒ (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

A student orders food from the menu shown below he orders 1 hotdog 1 popcorn 3 bags of chips and one soda how much money did he spend
(1 hotdog : 1.75)
( 1 popcorn : 1.25)
(3 bags of chips : 0.75)
(One soda : 1.50)
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.
Ann started walking to her grandparents' house at 9:38 A.M. It took her 41 minutes to get there. Then, she played in the backyard for 1 hour and 56 minutes.
When did Ann finish playing in the backyard?
The time Ann finished playing in the backyard is 12 : 15 pm
How to find the time Ann finish playing in the backyardTime Ann started walking to her grandparents' house = 9:38 A.MTime taken to get there = 41 minutesTime taken to play in the backyard = 1 hour and 56 minutesTotal time = 9:38 + 41 minutes + 1 hour 56 minutes
= 10:19 + 1 hour 56 minutes

Two angles are supplementary. The measure of the larger angle is 28 more than 3 times the measure of the smaller angle.
Find the measures of both angles.
ATQ
[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]
3x+28=180-38=142Let'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°

Step-by-step explanation:
The Diamond Rule says two factors, m and n, must multiply to get to the top number and add to get to the bottom number.
What are the possible values for m and n?
By solving a system of equations, we will see that the values of n and m are 3 and -4.
How to get the values of n and m?
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.

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:
135
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%
10% of 900 is 90 (900 ÷ 10 = 90)5% of 900 is 45 (half of 10% of 90)Therefore, 15% of 900 is 135We 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.
Hope this helps!
