Answer:

If you're trying to find the measurement of angle z then it'd be 2x degrees, since its twice that of angle y, which is x degrees

Step-by-step explanation:

Answer:

Slope: -3

Equation: [tex]y=-3x-5[/tex]

Step-by-step explanation:

As x increases by 1, your y decreases by 3, making the rise over run [tex]-3/1=-3[/tex]. That becomes the m in your y=mx+b equation, and since you have the y intercept, you can just plug and chug.

If I helped, a brainliest answer would be greatly appreciated!

Slope = -3

m = -3 / 1 = -3

Step-by-step explanation:

In 1 day we have daytime and night time each 12 hrs

in the day time he climbs 5ft and at night he slips 2 ft

meaning he climbs a total of 3ft(5-2) each day

so to get the number of days he climbed uts 25ft /3 ft

Therefore he takes 25/3 days to reach the top

answer is approximately 8.33 days

Answer:

a)ΔFHA is similar to ΔZIA by hypotenuse side test.

reason:- angle H and angle I are of 90 degrees.

b) FH/ ZI = HA/ IA = FA/ ZA

angle F = angle Z, angle H = angle I , angle angle A = angle A

The scale factor is 3/2......( HA/IA = 12/8 = 3/2)

c) IZ = 3.3 ....( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)

Answer:

The change in the y over the change in the x

Step-by-step explanation:

find the change in x so +4

and the change in they y so 3

3/4 and divide that

Answer:

Sale Price = $61.75 (answer). This means the cost of the item to you is $61.75. You will pay $61.75 for a item with original price of $95 when discounted 35%. In this example, if you buy an item at $95 with 35% discount, you will pay 95 - 33.25 = 61.75 dollars.

Step-by-step explanation:

Answer:

1/8

Step-by-step explanation:

2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8

so the minus sign in the exponent means you can put that factor in the denominator without the minus sign.

Answer:

The radius of the sphere is approximately 62.71 cm

Step-by-step explanation:

The question relates to the definition of a sphere

The given parameters are;

The distance between the sharp parallel blades through which the sphere is rolled = 77 centimeters

The radii of the circular faces left by cutting the sphere with the blade = 39 cm  and 60 cm

From the triangles formed by the cross-section of the sphere, we have;

AB ║ DE Given

∠A ≅ ∠E, ∠D ≅ ∠B Alternate angles

∠C ≅ ∠C by reflective  property

∴ ΔABC ~ ΔDCE by Angle-Angle similarity theorem

CF/CG = AB/DE = 78/120 = 13/20

CF = CG × 13/20

CF + CG = 77

∴ CG × 13/20 + CG = 77

33·CG/20 = 77

∴ CG = 140/3

CF = 13/20 × CG = 13/20 × 140/3 = 91/3

CF = 91/3

The diameter of the sphere AE = AC + EC

By Pythagoras's theorem

AC = √(FA² + CF²) = √(39² + (91/3)²) = 13·√(130)/3

EC = √(CG² + GD²) = √((140/3)² + 60²) = 20·√(130)/3

∴ AE = AC + EC = 13·√(130)/3 + 20·√(130)/3 = 11·√(130)

The diameter, 'D', of the sphere, AE = 11·√(130)

The radius of the sphere = D/2 = 11·√(130)/2 ≈ 62.71 cm

Answer:

Orange per pound= $4.86

Step-by-step explanation:

Giving the following information:

Decrease rate= 20%

Price this week= $3.89 per pound

To calculate the price of oranges last week, we need to use the following formula:

Orange per pound= price this week / (1 - decrease rate)

Orange per pound= 3.89 / (1 - 0.8)

Orange per pound= $4.86

Answer:

459 cm squared

Step-by-step explanation:

The triangle has a base of 18 and a height of 7.

Do 18x7/2 to get 63 cm squared.

The rectangle has a length and width of 22 and 18.

Do 22x18 to get 396 cm squared.

Add 396 and 63 to get a total area of 459 square cm.

[tex] \frac{1}{4} {x}^{2} - 4x + 7[/tex]

Step-by-step explanation:

f(×) = 1/4 (x- 2)^2 + 3

= 1/4 ( x^2 -2x -2x +4) +3

=1/4 x^2 -4x +4 +3

=1/4 x^2 -4x +7

The number is 12.

A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. Word illustration: The product of 8 and 3. Word illustration: The product of 8 and 3 is 11

Given

let number be x.

3x-24 = x

3x-x = 24
