Answer:
11.75
Step-by-step explanation:
the angles of a triangle should add to 180
5x + 3x - 4 +90 = 180
now solve for x
8x = 94
94/8 = 11.75

A salsa recipe uses green pepper, onion, and tomato in the extended ratio 2 : 5: 9. How many cups of onion are needed to make 160 cups of salsa?
Answer:
50 cups
Step-by-step explanation:
So rewrite the ratio to be 2x : 5x : 9x
16x = 160
x = 10
5 * 10 = 50
This is only right if the 5 in the ratio is for onions.
Jake made a wooden cone with a diameter of 6 inches and a height of 4.5 inches. What is the volume of this cone?
Answer:
42.42in³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cone
Step one
We know that the volume of a cone is
V= 1/3πr²h
Given data
Diameter d= 6 inches
Radius r= diameter/2= 6/2= 3 inches
Height h = 4.5 inches
Step two
Substituting our given data we have
Volume = 1/3*3.142*3²*4.5
V= 1/3*3.142*9*4.5
V= 127.251/3
V= 42.42in³

What is the domain of the function y = log(x +
3)?
(-0,00) (-0,00)
(-00,-3)
(0,00)
(-3,00)
DONE
Answer:Find the domain of y = log(x + 3)
Logarithms can only be taken for positive numbers. So you must have
x + 3 > 0
x > – 3 ✔
So the domain of the function is
D = {x ∈ R: x > – 3}
or using the interval notation
D = (– 3, +∞)

Which number is greater?
A. 3.33 x 10^7
B. 2.34 x 10^5
Answer:
3.33times 10^7 because when it is possible to substract 2.24times10^5 from it
Answer:
Answer: A) 3.33 x 10⁷
Step-by-step explanation:
A is the correct answer because you're adding 7 to the left. Whereas for B, it's only 5 times, and the number is less than 3.33.
3.33 ⇒ 33.3 ⇒ 333 ⇒ 3330 ⇒ 33300 ⇒ 333000 ⇒ 3330000 ⇒ 33300000
2.34 ⇒ 23.4 ⇒ 234 ⇒ 2340 ⇒ 23400 ⇒ 234000

the measure angles of a hexagon are 4x,5x,6x,7x,8x,and9x calculate the size of the smallest angle
Answer:
Step-by-step explanation:
Sum of interior angles of polygon = (n -2) * 180
Sum of interior angles of hexagon = (6-2)*180 = 4* 180 = 720
4x + 5x +6x +7x + 8x +9x = 180
39x = 180
x = 180/39
x=4.61
Smallest angle = 4x = 4*4.61 = 18.44

AB = 4.5
Step-by-step explanation:
We can cross multiply the sides in order to find the length of AB. Make sure you don't go diagonal, so you can't do 3/6. You can do 3/4 and 3/x, then match it to the same pattern.
This is the one I chose...
[tex]\frac{4}{3} =\frac{6}{x}[/tex]
Notice how I put them in the same order.
Now we can cross multiply...
[tex]4*x[/tex]
= 4x
[tex]6*3[/tex]
= 18
[tex]4x=18[/tex]
Divide by 4.
x = 4.5
The length of AB is 4.5.
How do you answer the picture below?
Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²

box plot question
Answer:
D
Step-by-step explanation:
a. The median, or line in the middle, is the same for both
b. This is the start to end of the box. For the top one, we have 39-33=6. For the bottom one, we have 36-30=6. These are the same.
c. The range is the highest minus the lowest value. For the top one, this is 41-31=10. For the bottom one, this is 38-28=10. These are the same.
This leaves D as our answer
The equation of the circle with center (3, -2) and radius 7 is

(x-3)^2 + (y+2)^2 = 7^2
Answer:
[tex] (x - 3)^{2} + { (y + 2)^{2} = 49[/tex]
Step-by-step explanation:
Center of the circle = (3, - 2) = (h, k)
Therefore, h = 3, k = - 2
Radius r = 7
Equation of circle in centre radius form is given as:
[tex](x - h)^{2} + {(y - k)}^{2} = {r}^{2} \\ \therefore \: (x - 3)^{2} + { \{y - ( - 2) \}}^{2} = {7}^{2} \\ \red{ \boxed{ \bold{\therefore \: (x - 3)^{2} + (y + 2)^{2} = 49}}}[/tex]

Which equation best shows whether or not Amy’s estimate is reasonable?
It is reasonable because 4 + 1 + 4 × 6 = 29.
It is reasonable because 4 + 4 × 7 = 32.
It is not reasonable because 4 + 1 + 4 + 6 = 15.
It is not reasonable because 4 + 4 × 7 = 56.
