what is the slant height of a pyramid with surface area of 209 square centimeters and a square base with sides of 7 centimeters? round to the nearest tenth.
Answer:
Step-by-step explanation:
base b = 7
slant height = L
area of base = 49 cm²
lateral area = surface area - base area = 209 - 49 = 160 cm²
area of one lateral face = 160/4 = 40 cm²
½·b·L = 40
L = 80/7 ≅ 11.4 cm
Solve by elimination using subtraction.
2x + y = -5
2x - 5y = 13
Answer:
(- 1, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + y = - 5 → (1)
2x - 5y = 13 → (2)
Subtracting (1) from (2) term by term will eliminate the x-0 term
0 - 5y - y = 13 - (- 5) , that is
- 6y = 18 ( divide both sides by - 6 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
2x - 3 = - 5 ( add 3 to both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
solution is (- 1, - 3 )

A rectangle's perimeter and its area have the same numerical value. The width of the rectangle is 3 units. What is
the length of the rectangle in units?
Answer:
l = 6.00
Step-by-step explanation:
So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so
3l = 2l + 2(3), so l = 6.

The Triangle EHL and MPE by HL Congruence Rule.
What is Congruence Rule?Two triangles are said to be congruent if their sides and angles are the same length. Two triangles can thus be stacked side by side and angle by angle.
Two triangles are said to be congruent if their sides are the same length, their angles are the same measurement, and they may be superimposed on each other.
As, from the figure in Triangle EHL and MPE
EH = MP
EL = ME
<EHL = < MPE = 90
As, If the hypotenuse and a leg of one right triangle are congruent with the hypotenuse and leg of another right triangle, the triangles are congruent.
So, the Triangle EHL and MPE is Congruent by HL Congruence Rule.

ASAP!!! are 7n - 2 and 2 - 7n equal? PLEASE EXPLAIN
Answer: No.
Step-by-step explanation:
They aren't equal because using the order of operations, the two in 7n-2 is subtracted from 7n. In 2-7n, they are subtracting 7n from 2, which would give a totally different answer.
Answer:
no they are not the same or equal. this is because the first part of the expression 2 is the number that is negative while 7n is positive. in the second half of the expression 2 is positive and 7n is negative.

3. 2x=4y is y=1/2x
4. 1/2y=2x+1 is y=4x+2

*I'm so sorry I wasn't able to give you the graphs (I tried uploading them on here from Desmos, and they wouldn't load for some reason). For graphing, you can create random ordered pairs, and can solve for y.
y=-x^2+9
What is the vertex
And how do I graph it
Answer:
You must know the shape of the graph y = x². Its chart is in the form of an upward parabola. The shape of the graph y = -x² is the same except that it is downward. Finally, to draw the shape of the graph y = -x² + 9, we need to move the previously mentioned graph 9 units upwards.
The formula for the vertex length of a parabolic chart is as follows: x= -b/(2a) b=0 , a= 1 → x= 0, y=-(0)²+9=9
vertex: (0,9)
In a 30-60-90 triangle, the long leg is 60, what is the short leg
Answer:
The shorter leg, which is opposite to the 30- degree angle, is labeled as x. The hypotenuse, which is opposite to the 90-degree angle, is twice the shorter leg length (2x). The longer leg, which is opposite to the 60-degree angle, is equal to the shorter leg's product and the square root of three (x√3).

A frozen yogurt shop allows guests to fill a cone shaped cup with frozen yogurt, and customers pay $0.08 per cubic inch. If each cup has a radius of 3 inches and a height of 5 inches, how much yogurt will fill the cone to its full capacity
Answer:
Answer: it will cost $3.768 to fill the cone to its full capacity.
Step-by-step explanation:
The frozen yoghurt is filled in cone shaped cups. The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
Where
h represents the height if the cone.
r represents the radius of base of the cone.
π is a constant whose value is 3.14
From the information given,
r = 3 inches
h = 5 inches
Volume = 1/3 × 3.14 × 3² × 5 = 47.1inches³
If customers pay $0.08 per cubic inch, it means that the amount that it would cost to fill the cone to its full capacity is
0.08 × 47.1 = $3.768

it will cost $3.768 to fill the cone to its full capacity.

Amelia, recuerda que se ha propuesto no consumir más de 260Cal (Calorías) en su desayuno.
Si Amelia se sirve una taza de agua tibia echándole 3 cucharaditas de Nesquik y una cucharadita de azúcar (17 Cal). También va a comer un pan integral (180 Cal).
¿Cumplirá Amelia con lo que se ha propuesto? Explica.
Answer:
¿Cumplirá Amelia con lo que se ha propuesto?
Amelia no cumple con lo que se ha propuesto, porque:
56,4 ÷ 2 = 28,2 ← 1 cucharadita
28,2 + 28.2 = 56,4 + 28,2 = 84.6 Cal ← 3 cucharaditas
84.6 Cal + 17 Cal azúcar = 101,6 Cal
101,6 Cal + 180 Cal pan = 281,6 Cal
Lo que se ha propuesto Amelia = 260 Cal
Lo que está consumiendo = 281 Cal
- Además, si Amelia solo quiere echarse ¾ de una porción de Nesquik, entonces, ¿Cuántas cucharaditas echará a su taza?
¾ × 2 = 1,5 ← cucharaditas
Se echara 1,5 cucharaditas :D
