Answer:
4 cans of paint will cover 8/9 of the surface
Step-by-step explanation:
One can of paint covers 2/9 of the house.
Garvin has used 4 of those cans.
To get the fraction of the whole surface that has been covered by those 4 cans of paint, we can multiply, following the logic below:
1 can of paint covers = 2/9 of the surface
4 cans of paint will cover = x of the surface
x = 4 X 2/9 = 8/9
Therefore, 4 cans of paint will cover 8/9 of the surface
A school lunch costs $2.50. A monthly lunch pass costs $40.00. Which inequality represents the number x of lunches you must purchase for the monthly pass to be a better deal?
Answer:
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Step-by-step explanation:
Given that:
Cost of each lunch = $2.50
Cost of monthly lunch pass = $40.00
Number of lunches = x
For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore
Cost of lunch * Number of lunches > Cost of monthly lunch pass
2.50x > 40.00
Hence,
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Answer:
2.50x > 40.00
$2.50 times a number of lunches is greater than $40.

which expression is equivalent to 4x^2 sqrt 5x^4 • 3 sqrt 5x^8 if x ≠ 0
Answer:
B
Step-by-step explanation:
The equivalent expression is [tex]16x^{8}[/tex]. So, the correct option is B.
Given:
The given expression is:
[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0[/tex]
To find:
The equivalent expression.
Explanation:
We have,
[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8}[/tex]
On simplification, we get
[tex]=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})[/tex]
[tex]=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})[/tex]
[tex]=12(x^{8})(5)[/tex]
[tex]=16x^{8}[/tex]
Therefore, the correct option is B.

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 3(m∠Y) − 130°. Find m∠Y.
SOLVE AND SHOW WORK PLSSSS!! Find the length of the missing sides. Do not round (leave in simplified radical form).
Answer:
For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13
Step-by-step explanation:
For the first triangle,
cos(45°)=7/hypotenuse
hypotenuse×cos45=7
hypotenuse×√2/2=7
hypotenuse=14/√2=7√2
We can now find the adjacent side using Pythagorean theorem,
√(7√2)²-7²=7
For the second triangle,
cos(30°)=adjacent/hypotenuse
but cos 30=√3/2
√3/2=adjacent/26(cross multiply and simplify)
26√3/2=13√3
To find the opposite length,
√(26)²-(13√3)²=13

Step-by-step explanation:
it's multiplied by 2 as you go to triangle 2
Answer:
x = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{5}{10}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
5x = 40 ( divide both sides by 5 )
x = 8

the denominator of a rational number is greater than the numerator by 6 if the numerator and denominator are both increased by 2 the number becomes 3/5 find the original number
ill mark your question brainliest if u give me corect amswer
Answer:
7/13
Step-by-step explanation:
Let's call x= numerator
We know that :
Denominator= x+6
And
(numerator +2)/(denominator +2) = 3/5
So
(x+2)/(x+6+2)=3/5
(x+2)/(x+8)=3/5
(x+2)*5=(x+8)*3
5x+10=3x+24
2x=14
x=7
In the end
Numerator= x =7
Denominator=x+6 = 13
So the original number is 7/13

Answer:
f(-3) = -16
Step-by-step explanation:
Given piecewise function is,
f(x) = 5x - 1 If x < -2
x + 3 If x ≥ -2
We have to find the value of he function when x = -3
Since x = -3 is less than x = -2,
Piece of the function to be considered,
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -16

Answer:
a=9
Step-by-step explanation:
a^2+b^2=c^2
a^2+5.6^2=10.6^2
a^2+ 31.36=112.36
-31.36 -31.36
a^2=81
a=[tex]\sqrt{81}[/tex]
a=9
Answer:
9in
Step-by-step explanation:
is a right triangle so you can use Pythagorean Th.
(10.6)²= (5.6)² + a², subtract (5.6)² from both sides
(10.6)²- (5.6)² = a²
81 =a², squareroot both sides
√81= √a²
±9 = a we only consider the positive solution because we use it for measurements so a=9
