Berry delicious is a popular shop that sells the shop used 60% more strawberries than the previous year when it used 3,090 kilograms how many strawberries did berry delicious use this year
Answer:
4,944 kg of strawberries
Step-by-step explanation:
In order to know the amount of strawberries Berry Delicious used this year, you have to know how much is 60% of 3,090 kg of strawberries. You can solve this by multiplying 3,090 by 60%.
Let's solve.
3,090 kg x 60% (0.60) = 1,854 kgNext, we have to add 1,854 kg to 3,090 kg.
3,090 kg + 1,854 kg = 4,944 kg of strawberriesTherefore, Berry Delicious used 4,944 kg of strawberries this year. This is 1,854 kg more than last year's.

2y=-x+9
3×-6y=-15 whats the solution to the system
Answer:
Step-by-step explanation:
2y = -x +9
3x - 6y = -15
The solution is the value of x and y that will make the two equations true in the same time.
3x-6y = -15; divide both sides by 3
x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equal
x-(-x+9) = -5; open parenthesis
x+x-9 = -5 ; add 9 to both sides and combine like terms
2x = -5 +9; 2x = 4; divide both sides by 2
x= 2
Substitute x for 2
2y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5
Solution is (2, 3.5)

(2, 7/2)

Step 2: Rewrite Systems
2y = -x + 9
[Division Property of Equality] Divide 2 on both sides: y = -x/2 + 9/2Step 3: Redefine Systems
y = -x/2 + 9/2

D Both have an equal sign.
Match the graph with the correct equation.
Answer:
y = 1.2x + 1.5
Step-by-step explanation:
Formula: y = mx + b
m = slope
b = y-intercept
The y-intercept is at "1.5"
slope = y/x or rise over run
r/r = 6/5 = 1.2
Slope is 1.2
Equation form....
y = 1.2x + 1.5
And the slope is positive since the line is increasing

The expression 8x +12y represents the sum of Harry and Mike's total monthly wages, where x represents the number
of hours Harry worked and y represents the number of hours Mike worked. What is another way to write the
expression, and what can you conclude from rewriting it in this way?
8(x +1.5y); Harry's hourly wage is 1.5 times Mike's.
8(x +1.5y); Mike's hourly wage is 1.5 times Harry's.
12(x+y)Harry's hourly wage is 8 times Mike's.
8(x+4y); Mike's hourly wage is 4 times Harry's.

Oscar has elected to have 23% of his federal income tax withheld as state income tax. If $154.00 was withheld as
federal income tax on his last paycheck, how much will be withheld from his paycheck for income tax in all?
a. $35.42
b. $118.58
C. $177.00
d. $189.42
Answer:
D. 189.42
Step-by-step explanation:
The amount that will be withheld from his paycheck for income tax in all is d. $189.42.
Using this formula
Amount withheld=State income tax+( State income tax× Percentage of federal income tax)
Where:
State income tax=$154.00Percentage of federal income tax=23%Let plug in the formula
Amount withheld=$154.00+($154,00×23%)
Amount withheld=$154.00+$35.42
Amount withheld=$189.42
Inconclusion the amount that will be withheld from his paycheck for income tax in all is d. $189.42.

A triangle has two 90° angles and a side 12 centimeters in length.
Select True or False for each statement about this type of triangle.
Answer:
False for the first one
true for the second
true for the last
Step-by-step explanation:
The triangle with 2 angles as 90° is not possible and the statement is false
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ∠ABC
Now , the measures of the angles of the triangle are
A triangle has two 90° angles and a side 12 centimeters in length
So , ∠ABC = ∠BAC = 90°
And , For a Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
Therefore , a triangle cannot be formed with 2 angles as 90°
Hence , the statement is False

4. In the diagram, LW is parallel to ST. RL = 6 centimeters, LS = 3
centimeters, and WT = 4 centimeters.
The solution is, The value of x is 8. so, the correct answer is option C.) 8.
Here, we have,
from the given diagram, we get,
In the diagram, LW is parallel to ST.
RL = 6 centimeters, LS = 3 centimeters, and WT = 4 centimeters.
as, we know that,
if, LW is parallel to ST , by property of triangle,
we get,
LW divides RT & RS proportionally.
i.e. RW: WT = RL : LS
now, here, RW = x
so, we have,
x: 4 = 6 : 3
or, x = 6 *4 / 3
or, x = 8
Hence, The value of x is 8.

Answer:
about 2.1
Step-by-step explanation:
The slope of the secant line is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (121/100 -1)/(11/10 -1) = (21/100)/(1/10) = 2.1
The slope of the tangent is about 2.1.
_____
Additional comment
We can refine our estimate by choosing a secant line between the points (9/10, 81/100) and (11/10, 121/100). That is, points either side of x=1.
That slope is ...
(121/100 -81/100)/(11/10 -9/10) = (40/100)/(2/10) = 2.0
We expect the slope of the tangent at x=1 to be exactly 2.0.
