Answer:
ASA
Step-by-step explanation:
The longest side is the same (denoted by the small line).
Assuming the red dot and the x mean the angles are the same, the triangles share two common angles.
As such, the triangles share one common side and two common angles. Hence ASA
A skateboard was originally priced at $53.00. It is on sale for 15% off. What is the sale price of the skateboard?
Answer:
STEP BYy-step explanation:
I need help with this to! When i get the answer ill let ya know
We have given that skateboard was originally priced at $53.00.
It is on sale for 15% off.
We have to determine the sale price of the skateboard.
The discount is 15%.
So we have to find 15% of $53.
What is the method to converting the percentage into desimal ?
Divide the percentage by 100 so we will get the the desimal form of percentage.
convert 15% into desimal
[tex]\frac{15}{100}=0.15[/tex]
Multiply 0.15 by original price,
[tex]0.15\times 53=7.95[/tex]
The original price discounted by this amount
Therfore he save $7.95
Sale price=53$-7.95=45.05
Therefore we get the salling price is $45.05.

we have
f(x)=x²-18x+88
let

In an arithmetic sequence, the 10th term is 37, and the 21st term is 4. Find the common difference and the first term
Answer:
Common difference is 3. And the first term is 64.
Step-by-step explanation:
The differnce between 21 and 10 is 11. So there are 11 unknown numbers in between. And the difference between 37 and 4 is 33. 33/11 is equal to 3. So the pattern is minus three. the first term is 9 terms before 37. 9 times 3 is 27. 37+27 is equal to 64. so the first term is 64

classify this relation as direct, inverse, or neither. if possible, find the constant.
Answer:
inverse, 50
Step-by-step explanation:
By looking at this, we can realize that it cannot be direct, because the y value does not increase when the x value does. Furthermore, we can realize that when the x and y values are multiplied, they all equal 50. This is a property of inverse variation. This means the relation is inverse. Lastly, the constant is 50 because that is the common product.

Which quadratic equation has roots of 5 and 7
Answer:
D
Step-by-step explanation:
Given the root of a quadratic equation x = a then the factor is (x - a)
Here the roots are x = 5 and x = 7 , then the corresponding factors are
(x - 5) , (x - 7)
The equation is then the product of the factors, that is
y = (x - 5)(x - 7) ← expand using FOIL
= x² - 7x - 5x + 35 ← collect like terms
y = x² - 12x + 35 → D
The quadratic equation has roots of 5 and 7 so, the quadratic equation would be equal to [tex]y = x^{2} - 12x + 35[/tex].
How to find the roots of a quadratic equation?Suppose that the given quadratic equation is

In this table, Davis recorded how far he could throw balls of different weights.
He modeled the data with a linear best-fit function. He can throw a certain ball 30 feet. Approximately how many pounds would this ball weigh?
a. 7.5 pounds
b. 8.1 pounds
c. 8.6 pounds
d. 9.1 pounds
Answer:
Option C
Step-by-step explanation:
By using linear best fit calculator for the given data,
Equation of the line of best fit will be,
y = -5.2514x + 74.94413
Here, x = Weight of the ball
y = Distance thrown by Davis
Now substitute y = 30 feet to calculate the weight (x) of the ball.
30 = -5.2514x + 74.94413
5.2514x = 74.94413 - 30
5.2514x = 44.94413
x = 8.5585
x ≈ 8.6 pounds
Therefore, David can throw a ball 30 feet weighing 8.6 pounds.
Option C will be the answer.
James sells two types of cupcakes. A basic chocolate cupcake is $2,75. His speciality chocolate covered strawberry cupcake is $3.75. He knows that he sold 185 cupcakes over the
weekend and made $586.75, but he lost the paper that told him how many of each type of cupcake he sold. How many chocolate cupcakes and chocolate covered strawberry cupcakes
did he sell over the weekend?
Answer:
107 chocolate cupcakes sold
78 chocolate covered strawberry cupcakes sold
Step-by-step explanation:
to solve one of these questions, you need to write two equations and then substitute back and forth to get the answer.
to start, we need to write an equation.
2.75c+3.75s=586.75
and c+s=185
reworking the second equation to isolate s, we'll then substitute it into the first one.
so s=185-c
2.75c+3.75(185-c)=586.75
2.75c+693.75-3.75c=586.75
combine like terms (the ones with a c variable attachment)
2.75c-3.75c=-1c
693.75-1c=586.75
-693.75
-107=-1c
/-1
107=c
put that back into the second equation
107+s=185
78=s

How to get an area for this shape
Answer:
A = 135 cm²
Step-by-step explanation:
The figure is composed of 2 triangles.
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
The total area is the sum of the area of both triangles
A = [tex]\frac{1}{2}[/tex] × 18 × 7 + [tex]\frac{1}{2}[/tex] × 18 × 8
= 9 × 7 + 9 × 8
= 63 + 72
= 135 cm²
26) In triangle ABC, if AB-BC and B
= 70°, ZA will be: *
O a. 70°
O b. 110°
O c. 55°
O d. 130°
Answer:
55degrees
Step-by-step explanation:
Let the other angles of the triangle are x, x degrees. Since the sum of angles in a triangle is 180degrees, hence;
<A + <B+ <C = 180
x + 70 + x = 180
2x+70 = 180
2x = 180 - 70
2x = 110
x = 110/2
x = 55
SInce <A is equal to x, hence <A is 55degrees

The perimeter of a rectangle is 48cm. its length is 4 cm. what is its width?
Answer:
P = 48
4 + 4(two given lengths) = 8
48(perimeter) - 8(length of two given lengths) = 40(length of two unknown sides)
40(length of two unknown lengths) divided by 2(two missing sides) = 20 cm
a heater is turned on in a cold room the scatterplot shows the relationship between the length of time since the heater was on in the temperature of the room the y-intercept of the estimated line of best fit is at (0, b). enter the approximate slope of the estimated line of best fit in the second response box
Answer:
A estimation of the slope is (1/2) °C/min
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through the points (x₁, y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Then we just need to look at the graph and find two points that belong to the graphed line (not the points) and estimate the slope
We can see that the line passes near the points (14 min, 14°C) and (18 min, 16°C)
Then the slope is:
a = (16°C - 14°C)/(18 min - 14 min) = (2°C)/(4 min) = (1/2) °C/min

Simply by adding like terms: -7x^2*y*z + 3y*z^2 - z*x^2*y - 4y
9514 1404 393
Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y

The name of the polygon with the vertices at (0,0), (4,8), (12,8) and (16,0) is a Trapezoid. Option A
How does a Trapezoid look like?A trapezoid is a four-sided flat polygon.
It has two parallel sides that has different lengths. The other two sides are non-parallel and also does have lengths.
A trapezoid has four angles, two of which are acute and two of which are obtuse.
A trapezoid's parallel sides are calld bases, while its non-parallel sides are called legs.
The height of a trapezoid is the perpendicular distance between its two bases. Trapezoids appear in a variety of sizes and forms, but its distinguishing feature is the presence of two parallel sides.
